Creating and Presenting an Effective Lecture

Enhancing medical education in respiratory diseases: efficacy of a 3D printing, problem-based, and case-based learning approach

OBJECTIVES

The present study aims to investigate the efficacy of utilizing three-dimensional (3D) printing technology in concert with Problem-Based Learning (PBL) and Case-Based Learning (CBL) pedagogical approaches in educating senior undergraduate clinical medical students on respiratory diseases.

METHODS

A cohort of 422 fourth-year clinical medicical students of from Anhui Medical University, pursuing a five-year program, were arbitrarily segregated into two distinct groups. The experimental group was subjected to a combined pedagogical approach, which included 3D printing technology, PBL and CBL (referred to as DPC). Conversely, the control group was exposed to conventional teaching methodologies for respiratory disease education. The effectiveness of the teaching methods was subsequently appraised using both theoretical test scores and custom questionnaires.

RESULTS

Post-quiz scores indicated a statistically significant improvement in the DPC group as compared to the traditional group (P < 0.01). Self-evaluation and satisfaction questionnaires revealed that the DPC group's self-assessment scores outperformed the traditional group in several aspects, including clinical thinking ability, learning initiative, self-study ability, anatomical knowledge mastery, confidence in learning, ability to analyze and solve problems, comprehension of the knowledge, help to clinical thinking and level of satisfaction on the teaching methods (P < 0.01). However, within the unsatisfied DPC sub-group, none of these self-assessment aspects, except for comprehension of the knowledge, impacted the learning efficacy (P > 0.05).

CONCLUSION

The deployment of the DPC pedagogical approach may confer unique experiential learning opportunities for students, potentially enhancing theoretical test scores and promoting self-evaluation and satisfaction in the context of respiratory disease education. Hence, it may be instrumental in augmenting the overall teaching efficacy.

Understanding and preference toward DOs and OMT before and after an osteopathic principles and practice fellow lecture series

CONTEXT

One of the two major pathways to become a physician in the United States is the Doctor of Osteopathic Medicine (DO) degree. A major distinctive feature is often perceived as the addition of manual training in osteopathic manipulative treatment (OMT) in the DO education. However, the profession also has a distinct philosophy imbedded in the curriculum of all osteopathic medical schools. Many medical schools offer professional degrees with graduates who may choose to continue their education in medicine, such as the Master of Science in Biomedical Sciences (MSBS). At our institution, there is no formal exposure to the differences between osteopathic and allopathic medicine in the MSBS curriculum, and most of this understanding is gained through out-of-classroom conversations. During the SARS-CoV-2 pandemic, virtual learning prohibited the usual gathering and discourse that occurs when students are learning on campus.

OBJECTIVES

The objective of this study is to create a curriculum in the form of a seminar series to assist premedical students in making an informed choice about which profession is the best fit for their own education and to gain an appreciation for osteopathic medicine. This appreciation could also aid in the future collaboration of premedical students with osteopathic providers, recommendations to patients, and potentially their own medical care. Questionnaires were utilized to determine if our osteopathic seminar series was effective at changing the preferences and understanding of MSBS students. We also sought to determine the effectiveness of virtual vs. in-person delivery of our curriculum.

METHODS

A seminar series with pre-established objectives was developed and presented to MSBS students at an osteopathic institution during the Fall of 2020 and 2021. The 2020 seminar was delivered through a virtual conference platform, and the 2021 seminar was delivered in-person. An eight question pre-and postquestionnaire was given to participants to evaluate their preferences and understanding. Internal validity and differences between delivery formats were assessed.

RESULTS

Both seminar series produced equally effective, significant changes in the preferences and perceptions of osteopathic medicine in both virtual and in-person delivery formats. Differences in pre-vs. post understanding across both seminar series were not consistently significant and were smaller than those observed in preferences and perceptions. Positive changes included an increased willingness to see a DO and to recommend a loved one see a DO as their personal physician. Preference changes between the in-person vs. virtual delivery platforms did not show significant differences; however, understanding did show some inconsistent differences.

CONCLUSIONS

This study demonstrates the utility of a virtual or in-person seminar to improve the preferences and perceptions of the osteopathic profession in MSBS students. The seminar series was successful in its goal of offering formal exposure to the osteopathic profession. The improved preferences and perceptions will have potential substantial benefits to the field of osteopathic medicine in the future. Further research is warranted to determine the most effective way to increase understanding of the osteopathic profession.

Effective Medical Lecturing: Practice Becomes Theory: A Narrative Review

Effective lecturing stimulates learning, creates a verbal history for our profession, and is a central basis for evaluating academic promotion. Unfortunately, few resources exist in the medical literature to guide the academician toward success as an effective lecturer. Using evidence-based principles, this review fosters adult learning in academic venues by incorporating the latest innovations in educational theory for both online and traditional teaching. The novice or advanced academic teacher will be guided toward critical self-evaluation of current teaching practices and encouraged to replace ineffective methods with ones more likely to be both rewarding and rewarded. By introducing literature-based learning techniques, emphasizing audience targeting, truncating content to an appropriate level of detail, effectively linking images and text, and accepting the brevity of learners' attentiveness, we show that the audience, not the speaker, is the primary educational focus.
