Redesign and validation of a computer programming course using Inductive Teaching Method

Inductive Teaching Method (ITM) promotes effective learning in technological education (Felder & Silverman, 1988). Students prefer ITM more as it makes the subject easily understandable (Goltermann, 2011). The ITM motivates the students to actively participate in class activities and therefore could be considered a better approach to teach computer programming. There has been little research on implementing ITM in computer science courses despite its potential to improve effective learning. In this research, an existing computer programming lab course is taught using a traditional Deductive Teaching Method (DTM). The course is redesigned and taught by adopting the ITM instead. Furthermore, a comprehensive plan has been devised to deliver the course content in computer labs. The course was evaluated in an experiment consisting of 81 undergraduate students. The students in the Experimental Group (EG) (N = 45) were taught using the redesigned ITM course, whereas the students in the Control Group (CG) (N = 36) were taught using the DTM course. The performance of both groups was compared in terms of the marks obtained by them. A pre-test conducted to compare pre-course mathematical and analytical abilities showed that CG was better in analytical reasoning with no significant differences in mathematical abilities. Three post-tests were used to evaluate the groups theoretical and practical competence in programming and showed EG improved performance with large, medium, and small effect sizes as compared to CG. The results of this research could help computer programming educators to implement inductive strategies that could improve the learning of the computer programming.

High Order Profile Expansion to tackle the new user problem on recommender systems

Collaborative Filtering algorithms provide users with recommendations based on their opinions, that is, on the ratings given by the user for some items. They are the most popular and widely implemented algorithms in Recommender Systems, especially in e-commerce, considering their good results. However, when the information is extremely sparse, independently of the domain nature, they do not present such good results. In particular, it is difficult to offer recommendations which are accurate enough to a user who has just arrived to a system or who has rated few items. This is the well-known new user problem, a type of cold-start. Profile Expansion techniques had been already presented as a method to alleviate this situation. These techniques increase the size of the user profile, by obtaining information about user tastes in distinct ways. Therefore, recommender algorithms have more information at their disposal, and results improve. In this paper, we present the High Order Profile Expansion techniques, which combine in different ways the Profile Expansion methods. The results show 110% improvement in precision over the algorithm without Profile Expansion, and 10% improvement over Profile Expansion techniques.

Transforming classroom questioning using emerging technology

Classroom questioning is a common teaching and learning strategy in postgraduate nurse education. Technologies such as audience response systems (ARS) may offer advantage over traditional approaches to classroom questioning. However, despite being available since the 1960s, ARSs are still considered novel in many postgraduate nurse education classroom settings. This article aims to explicate the attitudes of postgraduate nursing students in an Irish academic teaching hospital towards classroom questioning (CQ) and the use of ARSs as an alternative to traditional CQ techniques. The results of this small-scale study demonstrate that ARSs have a role to play in CQ in the postgraduate setting, being regarded by students as beneficial to learning, psychological safety and classroom interaction.

BCI-based user training in surgical robotics

Human error is a critical risk in surgery, so an important aim of surgical robotic systems is to improve the performance and the safety of surgical operations. Such systems can be potentially enhanced by a brain-computer interface (BCI) able to monitor the user's mental focus and use this information to improve the level of safety of the procedures. In order to evaluate such potential usage of BCIs, this paper describes a novel framework for training the user to regulate his/her own mental state while performing surgery-like tasks using a robotic system. This self-regulation is based on augmented reality (AR) feedback representing the BCI-monitored mental state, which helps the user's effort in maintaining a high level of mental focus during the task. A comparison between a BCI-based training and a training without a BCI highlighted a reduction of post-training trial times as a result of the enhanced training setup, without any loss in performance or in user experience. Such finding allows the identification of further improvements and novel potential applications of this training and interaction paradigm.

Handling Internet-Based Health Information: Improving Health Information Web Site Literacy Among Undergraduate Nursing Students

BACKGROUND

Patient care problems arise when health care consumers and professionals find health information on the Internet because that information is often inaccurate. To mitigate this problem, nurses can develop Web literacy and share that skill with health care consumers. This study evaluated a Web-literacy intervention for undergraduate nursing students to find reliable Web-based health information.

METHOD

A pre- and postsurvey queried undergraduate nursing students in an informatics course; the intervention comprised lecture, in-class practice, and assignments about health Web site evaluation tools. Data were analyzed using Wilcoxon and ANOVA signed-rank tests.

RESULTS

Pre-intervention, 75.9% of participants reported using Web sites to obtain health information. Postintervention, 87.9% displayed confidence in using an evaluation tool. Both the ability to critique health Web sites (p = .005) and confidence in finding reliable Internet-based health information (p = .058) increased.

CONCLUSION

Web-literacy education guides nursing students to find, evaluate, and use reliable Web sites, which improves their ability to deliver safer patient care. [J Nurs Educ. 2017;56(2):110-114.].

Neural Internet: Web Surfing with Brain Potentials for the Completely Paralyzed

Neural Internet is a new technological advancement in brain-computer interface research, which enables locked-in patients to operate a Web browser directly with their brain potentials. Neural Internet was successfully tested with a locked-in patient diagnosed with amyotrophic lateral sclerosis rendering him the first paralyzed person to surf the Internet solely by regulating his electrical brain activity. The functioning of Neural Internet and its clinical implications for motor-impaired patients are highlighted.

[HYGIENIC EVALUATION OF STUDIES OF PRESCHOOLERS WITH THE USE OF PC TABLETS]

In the article there are presented the results ofphysiological and hygienic evaluation of studies in kindergarten with the use of educational games on an electronic PC tablet. The study involved 44 foster-children. In one of the groups children in the classroom used the interactive game software on electronic PC tablets "Samsung", the same time while working with the PC tablet did not exceed 10 minutes, in the other--the classes were held traditionally. There were investigated the state of health, psychosomatic and psycho-emotional state of children, determined their functional readiness for systematic training in school, mental performance, the functional state of the central nervous system (CNS) by simple visual-motor reaction (SVMR) and reactions to a moving object (RDO). Developing ofgame sessions with the use of electronic PC tablets for 10 minutes were established to contribute to the activation of the central nervous system and increase in children resistance to the development of fatigue.

Top 10 Lessons Learned from Electronic Medical Record Implementation in a Large Academic Medical Center

Electronic medical record (EMR) implementation efforts face many challenges, including individual and organizational barriers and concerns about loss of productivity during the process. These issues may be particularly complex in large and diverse settings with multiple specialties providing inpatient and outpatient care. This case report provides an example of a successful EMR implementation that emphasizes the importance of flexibility and adaptability on the part of the implementation team. It also presents the top 10 lessons learned from this EMR implementation in a large midwestern academic medical center. Included are five overarching lessons related to leadership, initial approach, training, support, and optimization as well as five lessons related to the EMR system itself that are particularly important elements of a successful implementation.

An inquiry-based biochemistry laboratory structure emphasizing competency in the scientific process: a guided approach with an electronic notebook format

The laboratory setting is an exciting and gratifying place to teach because you can actively engage the students in the learning process through hands-on activities; it is a dynamic environment amenable to collaborative work, critical thinking, problem-solving and discovery. The guided inquiry-based approach described here guides the students through their laboratory work at a steady pace that encourages them to focus on quality observations, careful data collection and thought processes surrounding the chemistry involved. It motivates students to work in a collaborative manner with frequent opportunities for feedback, reflection, and modification of their ideas. Each laboratory activity has four stages to keep the students' efforts on track: pre-lab work, an in-lab discussion, in-lab work, and a post-lab assignment. Students are guided at each stage by an instructor created template that directs their learning while giving them the opportunity and flexibility to explore new information, ideas, and questions. These templates are easily transferred into an electronic journal (termed the E-notebook) and form the basic structural framework of the final lab reports the students submit electronically, via a learning management system. The guided-inquiry based approach presented here uses a single laboratory activity for undergraduate Introductory Biochemistry as an example. After implementation of this guided learning approach student surveys reported a higher level of course satisfaction and there was a statistically significant improvement in the quality of the student work. Therefore we firmly believe the described format to be highly effective in promoting student learning and engagement.

Comparative modeling of proteins: a method for engaging students' interest in bioinformatics tools

The huge increase in data being produced in the genomic era has produced a need to incorporate computers into the research process. Sequence generation, its subsequent storage, interpretation, and analysis are now entirely computer-dependent tasks. Universities from all over the world have been challenged to seek a way of encouraging students to incorporate computational and bioinformatics skills since undergraduation in order to understand biological processes. The aim of this article is to report the experience of awakening students' interest in bioinformatics tools during a course focused on comparative modeling of proteins. The authors start by giving a full description of the course environmental context and students' backgrounds. Then they detail each class and present a general overview of the protein modeling protocol. The positive and negative aspects of the course are also reported, and some of the results generated in class and in projects outside the classroom are discussed. In the last section of the article, general perspectives about the course from students' point of view are given. This work can serve as a guide for professors who teach subjects for which bioinformatics tools are useful and for universities that plan to incorporate bioinformatics into the curriculum.

Using an ePortfolio system as an electronic laboratory notebook in undergraduate biochemistry and molecular biology practical classes

Despite many apparent advantages, including security, back-up, remote access, workflow, and data management, the use of electronic laboratory notebooks (ELNs) in the modern research laboratory is still developing. This presents a challenge to instructors who want to give undergraduate students an introduction to the kinds of data curation and notebook keeping skills that will inevitably be required as ELNs penetrate normal laboratory practice. An additional problem for the teacher is that ELNs do not generally have student-administrative functions and are prohibitively expensive. In this report, we describe the use and impact of an ePortfolio system as a surrogate ELN. Introduction of the system led to several pedagogic outcomes, namely: increased preparedness of students for class, encouragement of creativity and reflection with respect to experimental methods, greatly enhanced engagement between students and tutors, and it gave instructors the ability to scrutinize original data files and monitor student-tutor feedback cycles. However, implementation led to a disruption of tutor workloads and incurred new levels of accountability that threatened to undermine the initiative. Through course evaluations and other reflective processes, we reached an appreciation of how an ELN should be introduced into practical class teaching so that it not only becomes an appropriate aid for teaching the laboratory experience, but also becomes a life-long resource for students.

Twenty weeks of computer-training improves sense of agency in children with spastic cerebral palsy

Children with cerebral palsy (CP) show alteration of perceptual and cognitive abilities in addition to motor and sensory deficits, which may include altered sense of agency. The aim of this study was to evaluate whether 20 weeks of internet-based motor, perceptual and cognitive training enhances the ability of CP children to determine whether they or a computer are responsible for the movement of a visually observed object. 40 CP children (8-16 years) were divided into a training (n:20) and control group (n:20). The training group trained 30 min each day for 20 weeks. The ability of the children to judge whether they themselves or a computer were responsible for moving an object on a computer screen was tested before and after the 20-week period. Furthermore, we included a healthy age-matched group to determine a normal functional level of performance. Our results showed a significantly larger increase in the number of correct subjective reporting for the training group (p<0.001). In accordance with this, the training group was also less fooled by computer-induced movements given by a decreased curvature which indicated a compensatory motor strategy when drawing the line to hit the target following the training than the control group (p=0.018). These findings suggest that sense of agency may be altered, and that training of sense of agency may help to increase the outcome of training programmes in children with CP.

Using an alternate reality game to increase physical activity and decrease obesity risk of college students

BACKGROUND

This quasi-experimental study investigated a game intervention--specifically, an alternate reality game (ARG)--as a means to influence college students' physical activity (PA). An ARG is an interactive narrative that takes place in the real world and uses multiple media to reveal a story.

METHOD

Three sections of a college health course (n = 115 freshman students) were assigned either to a game group that played the ARG or to a comparison group that learned how to use exercise equipment in weekly laboratory sessions. Pre- and post-intervention measures included weight, waist circumference, body mass index (BMI), percentage body fat (PBF), and self-reported moderate physical activity (MPA) and vigorous physical activity (VPA), and PA (steps/week).

RESULTS

A significant group x time interaction (p = .001) was detected for PA, with a significant increase in PA for the game (p < .001) versus a significant decrease (p = .001) for the comparison group. Significant within-group increases for weight (p = .001), BMI (p = .001), and PBF (p = .001) were detected. A significant group x time interaction (p = .001) was detected when analyzing self-reported VPA, with both groups reporting decreases in VPA over time; however, the decrease was only significant for the comparison group (p < .001). No significant group differences were found for MPA.

CONCLUSIONS

It is important that any intervention meet the needs and interests of its target population. Here, the ARG was designed in light of the learning preferences of today's college students--collaborative and social, experiential and media-rich. Our results provide preliminary evidence that a game intervention can positively influence PA within the college student population.

[The use of multimedia technologies in otorhinolaryngology]

The possibilities of using computer-assisted technologies in otorhinolaryngology have been analysed with a view to enhancing the efficacy of the teaching activity and improving the quality of diagnostics and treatment of various ENT diseases. It is emphasized that computers may be used not only to reproduce traditional teaching modalities but also to supplement them with new approaches inaccessible with conventional methods; the introduction of these approaches is of special importance for medical universities and institutes. The use of computer-based technologies in otorhinolaryngological practice made it possible to significantly improve the quality of diagnostics and treatment of the most widespread ENT diseases. For all that, however, the potential of computer technologies in otorhinolaryngology is by no means exhausted.

Assisting people with multiple disabilities by improving their computer pointing efficiency with an Automatic Target Acquisition Program

This study evaluated whether two people with multiple disabilities would be able to improve their pointing performance through an Automatic Target Acquisition Program (ATAP) and a newly developed mouse driver (i.e. a new mouse driver replaces standard mouse driver, and is able to monitor mouse movement and intercept click action). Initially, both participants had their baseline sessions. Then intervention started with the first participant. When his performance was consolidated, new baseline and intervention occurred with the second participant. Finally, both participants were exposed to maintenance phase, in which their pointing performance improved significantly. Data indicated that both participants improved their pointing efficiency with the use of ATAP and remained highly successful through maintenance phase. Implications of the findings are discussed.

An adaptive dynamic pointing assistance program to help people with multiple disabilities improve their computer pointing efficiency with hand swing through a standard mouse

The latest research adopted software technology to redesign the mouse driver, and turned a mouse into a useful pointing assistive device for people with multiple disabilities who cannot easily or possibly use a standard mouse, to improve their pointing performance through a new operation method, Extended Dynamic Pointing Assistive Program (EDPAP), where the user can swing his hand on the desktop to quickly move the cursor to a target. However, EDPAP has lower pointing efficiency due to the cursor jumping in sequence amongst the targets once there are many targets on the screen. This study evaluated whether two people with multiple disabilities would be able to improve their pointing performance through a new target acquisition technique based on EDPAP, Adaptive Dynamic Pointing Assistive Program (ADPAP), where the cursor movement path is selected adaptively by users' hand swing direction, as opposed to being sequential. This study used multiple probe design across participants. Participants typically received three 30-min ADPAP training sessions per week, for a period of about 6-7 weeks. Initially, both participants had their baseline sessions. Then intervention started with the first participant. When his performance was consolidated, new baseline and intervention occurred with the second participant. Finally, both participants were exposed to the maintenance phase, in which their pointing performance improved significantly. Data indicated that both participants improved their pointing efficiency with the use of ADPAP and remained highly successful through the maintenance phase. Results of this study showed that, with the assistance of ADPAP, participants can acquire targets quickly, easily, and accurately, thus helping the disabled to solve their pointing problems.

Assisting people with multiple disabilities improve their computer pointing efficiency with thumb poke through a standard trackball

This study evaluated whether two people with multiple disabilities who could not easily use a computer through a standard input device (i.e., mouse or trackball) would be able to improve their pointing performance using thumb poke with a standard trackball through a Dynamic Trackball-Pointing Assistive Program (DTPAP) and a newly developed trackball driver (i.e., a new trackball driver replaces the standard trackball driver, and changes a trackball into a precise thumb poke detector, and intercepts trackball action). Initially, both participants were given baseline sessions, then intervention started with the first participant. When his performance was consolidated, new baseline and intervention occurred with the second participant. Finally, both participants were exposed to the maintenance phase. Data indicated that both participants improved their pointing performance significantly with the use of DTPAP and remained highly successful through the maintenance phase. Implications of the findings are discussed.

Group-item and directed scanning: examining preschoolers' accuracy and efficiency in two augmentative communication symbol selection methods

PURPOSE

The current investigation compared directed scanning and group-item scanning among typically developing 4-year-old children. Of specific interest were their accuracy, selection speed, and efficiency of cursor movement in selecting colored line drawn symbols representing object vocabulary.

METHOD

Twelve 4-year-olds made selections in both directed and group-item scanning conditions using a 36-symbol array that required matching line drawn symbols to pictures.

RESULTS

The majority of participants took more time in the directed scanning condition. Though not statistically significant, participants tended to be more accurate in their use of directed scanning. The cursor movements required (as a proportion of optimal cursor movements) were similar for both scanning selection techniques.

CONCLUSIONS

Among typically developing 4-year-olds, there appears to be a trade-off between speed and accuracy in symbol selection when using directed or group-item scanning. Better accuracy with directed scanning appears to come at the cost of a slower response time. Whereas group-item scanning may be faster, it results in a decreased number of accurate responses. Applications for clinical practice and implications for future research are discussed.

An automatic Drag-and-Drop assistive program developed to assistive people with developmental disabilities to improve Drag-and-Drop efficiency

The latest researches adopted software technology to improve pointing performance; however, Drag-and-Drop (DnD) operation is also commonly used in modern GUI programming. This study evaluated whether two children with developmental disabilities would be able to improve their DnD performance, through an Automatic DnD Assistive Program (ADnDAP). At first, both participants had their baseline sessions. Then the first participant entered into intervention. New intervention began with the second participant when his performance was consolidated. Finally, maintenance phase occurred with both participants, in which their DnD performance improved significantly. Data showed that both participants improved their DnD efficiency with the assistance of ADnDAP, and remained highly successful through maintenance phase. Implications of the findings are discussed.

Assisting people with developmental disabilities improve their collaborative pointing efficiency with a Multiple Cursor Automatic Pointing Assistive Program

This study evaluated whether four persons (two groups) with developmental disabilities would be able to improve their collaborative pointing performance through a Multiple Cursor Automatic Pointing Assistive Program (MCAPAP) with a newly developed mouse driver (i.e., a new mouse driver replaces standard mouse driver, and is able to intercept/simulate mouse action). The study was performed according to an ABAB design, in which A represented baseline and B represented intervention phases. Data showed that both groups of participants improved their collaborative pointing ability through the use of MCAPAP during the B (intervention) phase. Practical and developmental implications of the findings are discussed.

Assisting people with multiple disabilities improve their computer-pointing efficiency with hand swing through a standard mouse

This study evaluated whether two people with multiple disabilities would be able to improve their pointing performance using hand swing with a standard mouse through an Extended Dynamic Pointing Assistive Program (EDPAP) and a newly developed mouse driver (i.e., a new mouse driver replaces standard mouse driver, and changes a mouse into a precise two-dimensional motion detector, and intercepts mouse action). Initially, both participants had their baseline sessions. Then intervention started with the first participant. When his performance was consolidated, new baseline and intervention occurred with the second participant. Finally, both participants were exposed to maintenance phase, in which their pointing performance improved significantly. Data indicated that both participants improved their pointing efficiency with the use of EDPAP and remained highly successful through maintenance phase. Implications of the findings are discussed.

A transdisciplinary approach to faculty development in nursing education technology

The purpose of this article is to describe the creation of a transdisciplinary group, consisting of nurse educators, a medical librarian, lab technologists, and a technology expert. to lead the integration of electronic health technology, including high-fidelity simulation, handheld technology, and electronic health records, within a school of nursing. The use of innovative educational tools by nursing faculty can be daunting because of the steep learning curve. The model described here is effective in developing faculty to use simulation and other technologies as teaching-learning strategies.

Assessment tool for nursing student computer competencies

Computer skills have been established as important for nursing students and for graduate nurses. No current research was found on the best method to evaluate the skills of incoming nursing students. The purpose of this descriptive, correlational study was to compare student ratings of their computer competency to their performance of those skills on a computer-graded assessment. A convenience sample of 87 nursing students was used. There was a low, but significant correlation between the scores on the survey and the assessment. The results suggest that students rate themselves higher on their skills than their actual performance of computer skills. Implications for educators are presented, and the value of using a computer-graded assessment is discussed.

Introducing information literacy into anesthesia curricula

PURPOSE

This review examines the topic of information literacy (IL) and its importance as a component of competency-based education in the health professions, and shares the process and outcome of a collaborative effort between The University of Manitoba Department of Anesthesia and Health Sciences Libraries to create, to introduce and integrate IL training into a new anesthesia curriculum.

PRINCIPLE FINDINGS

Nine IL modules were developed according to standards set by the Association of College and Research Libraries (ACRL) and aligned with the Royal College of Physicians and Surgeons CanMEDS competencies. Taken collectively, they explore modern tools used to approach the medical literature in an organized, efficient manner, and to locate, evaluate and use information effectively to accomplish a specific purpose. Each module forms the basis of one IL session that combines self-study and group projects with librarian-led, computer-based training, designed to build competency in information need awareness, retrieval skills and resource appraisal. Facility with the concepts taught was evaluated though examples relevant to the anesthesia practice environment. The entire collection is available at http://wiki.lib.umanitoba.ca/tiki-index.php?page=Anesthesia+Clinical+Assistants+Programme. While the original impetus for this project was to prepare Anesthesia Clinical Assistants for self-directed, life-long, active learning, what emerged was a curriculum in IL germane to medical specialties and flexible enough to be used by healthcare professions generally.

CONCLUSION

An IL program, directly relevant to current expectations of competent practice, education and lifelong learning, has been created and is discussed within the larger context of curriculum-integrated IL for the health professions.

Trading places: adolescents as teachers

The traditional criteria for granting status to adolescents are no longer appropriate and, unless replaced, could produce alienation and excessive reliance upon peers for communication and acceptance. The status that youth seek can be attained if their technology skills are valued and seen to qualify them as helpful sources of learning for adults. A new perspective for teaching and learning in the digital environment is described. Recommendations are given for shifting from a hierarchical relationship between adults and adolescents to more equitable forms of interaction that acknowledge the strengths and limitations of both generations.

Informatics training for clinicians is more important than hardware and software

OBJECTIVE

The importance of training physicians and nurses in the art, skill and science of clinical informatics has never been greater. What level of training is necessary and sufficient to equip the 21st century healthcare workforce for the transformative opportunity enabled by widespread deployment of EHRs?

METHODS

Building on the success of its 10x10 program, AMIA with support from the Robert Wood Johnson foundation took its next step to create the necessary documents to have clinical informatics recognized as a sub-specialty by the American Board of Medical Specialties (ABMS).

RESULTS

We defined the core content that had to be mastered and describing how physicians interested in the sub-specialty clinical informatics would be trained. The results of this work have been approved by the board of AMIA and have been published in its journal JAMIA.

CONCLUSION

The health challenges of the 21 century require that we rapidly train the clinical workforce in clinical informatics. In addition to buying hardware and software, our health systems need to sponsor this training. Two percent of every Health IT budget should be targeted for clinician education.

A curricular approach to improve the information literacy and academic writing skills of part-time post-registration nursing students in Hong Kong

In today's environment of rapidly changing health care and information technology, nurses require a broad range of skills. One of the key skills required of all health professionals in this environment is information literacy. For registered nurses returning to a university setting to study for their baccalaureate degree, becoming information literate is one of many challenges they face. Also key to students' ability to use and communicate information in an appropriate and effective manner is their writing skills. This article describes a curricular intervention designed to develop and strengthen post-registration nurses' information literacy and academic writing competencies. An introductory information management module was developed and provided to three successive cohorts of students (n=159). Students were predominantly female (85.4%) with a mean age of 34.2 years (SD=6.8). Prior to commencing the program, students reported low information literacy and writing skills, especially in accessing and searching electronic databases and using referencing formats. The post-test evaluation of skills showed substantial and statistically significant increases in all assessed competencies. This intervention demonstrated that with structured but flexible learning activities early in the curriculum, post-registration nursing students can quickly become information literate.

A 6-month follow-up of the effects of an information and communication technology (ICT) training programme on people with intellectual disabilities

We investigated the long-term effects of an information and communication technology (ICT) training programme for people with intellectual disabilities (ID). A community-based ICT training programme was designed to enhance the computer skills of people with ID and prepare them to make use of ICT in their daily life. Of the 100 who had participated in the original ICT training programme, 59 of them and their caregivers agreed to participate in the follow-up interview. A computer skills checklist was used to assess the ICT competence of the participants before training, after training, and at the 6-month follow-up assessment. All caregivers were interviewed at the 6-month follow-up session to explore the use of ICT by people with ID and their needs for further training. Results from repeated measures ANOVA showed that participants maintained at the 6-month follow-up the basic ICT skills that they acquired during training [F=13.86, p<0.001]. Caregivers reported that participants spent more time in using the computers, but still needed occasional guidance. They also reported a need to advance their ICT skills beyond the basic computer training. We concluded that ICT training for people with ID would help them in maximizing the benefits of information technology via computers.

Training older adults to use new technology

Enabling older adults to interact with new technologies is an important immediate and long-term goal for training research. The literature provides general guidance for developing training programs; however, it is important to determine the type of training that works best for younger and older adults, for immediate performance, and for learning. In the present study we assessed the relative benefits of guided action training and guided attention training for younger and older adults learning to use a novel technology system. Guided action training yielded better performance during training for both age groups. However, assessments of learning revealed a clear benefit of guided attention training for both age groups. These data suggest differences in training benefits for immediate performance versus more general learning.

Initial Experience of a Digital Training Resource for Modified Rankin Scale Assessment in Clinical Trials

BACKGROUND AND PURPOSE

The modified Rankin Scale (mRS) is the preferred measure of disability in cerebrovascular clinical trials, but its value is restricted by interobserver variability. Poor reliability reduces the statistical power of clinical trials and leads to underestimation of effect size. Strategies to improve mRS grading are required. Video training has previously improved application of the National Institutes of Health Stroke Scale in clinical research. We developed an mRS training resource in an attempt to minimize interobserver variability.

METHODS

We produced a complete training resource comprising an instructional DVD with accompanying written materials and assessment recordings of patient interviews. Formal assessment of training involved grading of real-life cases. Results of initial training and recertification were collected centrally and scored.

RESULTS

Data from 1564 assessments are presented. The majority of assessors were participating in 2 large prospective clinical stroke trials. Assessors represented a mixed group of disciplines and nationalities. After training, most trainees (90%) achieved certification in mRS assessment. The majority (85%) of investigators who did not reach an acceptable score on initial testing achieved certification after further exposure to the package.

CONCLUSIONS

Mass training in mRS assessment for clinical trials is possible. We outline the development of a video-based training package, including technical issues, patient selection procedures, and methods of scoring and assessment. Certification results suggest that use of the resource can improve mRS grading. Acceptability of the training has been demonstrated by its successful use in 2 international acute stroke trials, SAINT 1 and CHANT.

The non-invasive Berlin Brain–Computer Interface: Fast acquisition of effective performance in untrained subjects

Brain-Computer Interface (BCI) systems establish a direct communication channel from the brain to an output device. These systems use brain signals recorded from the scalp, the surface of the cortex, or from inside the brain to enable users to control a variety of applications. BCI systems that bypass conventional motor output pathways of nerves and muscles can provide novel control options for paralyzed patients. One classical approach to establish EEG-based control is to set up a system that is controlled by a specific EEG feature which is known to be susceptible to conditioning and to let the subjects learn the voluntary control of that feature. In contrast, the Berlin Brain-Computer Interface (BBCI) uses well established motor competencies of its users and a machine learning approach to extract subject-specific patterns from high-dimensional features optimized for detecting the user's intent. Thus the long subject training is replaced by a short calibration measurement (20 min) and machine learning (1 min). We report results from a study in which 10 subjects, who had no or little experience with BCI feedback, controlled computer applications by voluntary imagination of limb movements: these intentions led to modulations of spontaneous brain activity specifically, somatotopically matched sensorimotor 7-30 Hz rhythms were diminished over pericentral cortices. The peak information transfer rate was above 35 bits per minute (bpm) for 3 subjects, above 23 bpm for two, and above 12 bpm for 3 subjects, while one subject could achieve no BCI control. Compared to other BCI systems which need longer subject training to achieve comparable results, we propose that the key to quick efficiency in the BBCI system is its flexibility due to complex but physiologically meaningful features and its adaptivity which respects the enormous inter-subject variability.
