How charismatic trainers inspire others to learn through positive affectivity

Tablet-based versus presentation-based seminars in radiology: Effects of student digital affinity and teacher charisma on didactic quality

Aims

Tablets are being adopted as teaching medium in medical education more frequently. Here we compared two teaching formats in a radiology seminar using a tablet-based student-centred approach guided by teachers and traditional presentation-based, teacher-centred instruction. The aim was to investigate the effects on academic performance, estimated learning gain, didactic quality, as well as how teacher charisma and student digital affinity influence these elements.

Methods

Data from 366 students were collected. Student digital affinity, didactic quality of, and overall satisfaction with the seminars were rated for each teaching format over three semesters, whereby in the last semester, students additionally estimated their learning gain, took a knowledge and image interpretation test, and rated teacher charisma.

Results

The tablet-based seminars yielded significantly higher ratings for didactic quality and overall satisfaction. However, the presentation-based seminars proved superior with respect to academic performance as well as estimated learning gain. When employing tablets, teacher charisma correlated with estimated learning gain, and digital affinity affected didactic quality. Additionally, good seminar organization, comprehensible learning objectives, and optimal variation of learning activities were identified as important factors.

Conclusion

This study suggests a complex interplay of various factors concerning teachers, students, and didactics that can be assessed and improved to assure the successful curricular implementation of tablets. Of note, tablet integration and thereby active engagement of students with imaging analysis skills does not automatically result in greater declarative knowledge. Nevertheless, understanding the complexities of structuring and delivering tablet-based, teacher-guided instruction is essential to creating meaningful educational experiences.

Impact of training design on trainees' motivation: an empirical study

Purpose

This study aims to advance understanding of the critical role of training variables (trainer performance, transfer design and an identical element) and motivation to improve work through learning (MTIWL) the least researched construct of motivation in human resource development (HRD).

Design/methodology/approach

A self-report online survey was conducted to collect responses from 280 managers working in different industries. Participants attended open skills training program organized by an in-house training institute in India.

Findings

The trainer performance and transfer design had a positive and significant impact on MTIWL. However, an identical element found no significant direct impact on MTIWL.

Practical implications

The trainer performance positively cultivates trainees’ MTIWL and training approaches according to trainees’ preferences improve MTIWL. The training content is needed to resemble with work assignment for enhancement of trainees MTIWL.

Originality/value

This study improved understanding of the impact of training variables on a comprehensive and practical aspect of trainees' motivation in HRD, MTIWL.

Robots for Foreign Language Learning: Speaking Style Influences Student Performance

Much previous research suggests that teachers' individual characteristics may affect students' performance; however, which factors are particularly helpful is as yet unclear and methodologically very difficult to assess. In this paper, we study the effects of robots' speaking styles when instructing students on a task. 40 participants saw a brief video in which a robot presented its instructions either in a charismatic or a not so charismatic speaking style. Participants' task was then to produce foreign language sentences on the basis of visualizations of the prosodic properties of these sentences. A subsequent analysis of participants' productions shows that language learners' performance was significantly better when the robot had delivered its instructions in a charismatic voice. The results suggest not only that a charismatic speaking style may be crucial for teachers in general and hence one of the factors causing the interpersonal variation between teachers, but also that students can benefit from instructions by robots delivered in a charismatic speaking style.

Why trainees evaluate the same trainer differently? Examining a dual-process model of training effectiveness

Purpose

It is commonly observed in trainings that all trainees do not get satisfied with the performance of the trainer. The usual way to increase the satisfaction of trainees is a stress on improving task communication of the trainer. It is based on the assumption that effective task communication essentially fosters training effectiveness. This study aims to provide preliminary evidence that effective task communication can also obstruct training effectiveness besides promoting it. To achieve this objective, the authors hypothesized a dual-process model of training effectiveness based on uncertainty reduction theory.

Design/methodology/approach

This was a field study in which the authors collected time-lagged data from seven trainings. The trainings were designed to impart technical knowledge of multilevel analyses to professional social science researchers. Confirmatory factor analysis for ordinal indicators was used to test the measurement properties of the model and scales. Structural equation modeling for ordinal indicators was used to test hypotheses.

Findings

This study provided evidence of an overall positive effect of the trainer’s task communication on the trainee’s communication satisfaction. A complex mediation analysis also revealed the existence of two opposite psychological processes. While the first process transmitted the positive effect of task communication to communication satisfaction, the other process diminished this positive effect. Implications for the theory and practice of training are discussed.

Originality/value

Training scholars and practitioners universally believe that an effective task communication of trainers essentially promotes training effectiveness. This study has provided empirical evidence that this assumption is an incomplete picture of a complex reality that requires further investigation.

Leadership Intellectual Stimulation and Team Learning: the Mediating Role of Team Positive Affect

This study investigates how leadership intellectual stimulation relates to team positive affect and team learning. We explore the role of positive affect as mediator between leadership intellectual stimulation and team learning. Using a cross-sectional sample of 562 employees, nested within 130 teams from 44 small and medium size organizations, we implemented Structural Equation Model analysis at the team level. Results provides evidence of the strong influence that intellectual stimulation have on team learning and team positive affect, as well as the potential of positive affect for stimulate team learning. Team positive affect serves as partial mediator between intellectual stimulation and team learning, contributing to explain significant additional variance. Leadership intellectual stimulation is a relevant team social resource that provides support for team learning. As well, positive affect contributes significantly to improve learning among teams. This suggests the importance of developing leadership behaviors that encourage learning and team positive affect, which contributes to team learning and hence to performance.
