Effectiveness of peer teaching in health professions education: A systematic review and meta-analysis

BACKGROUND

The reform in health professions education requires the focus to shift from fact memorization to exploring, analyzing, assimilating, and synthesizing information to promote active and collaborative learning. Peer teaching is one of the educational strategies.

AIMS

This review aimed to explore and synthesize quantitative evidence to determine the overall effect of peer teaching in enhancing students' theoretical knowledge and practical skills (e.g., procedural skills and resuscitation) in health professions education.

METHODS

PubMed, ScienceDirect, CINAHL, ERIC, ProQuest, reference lists of relevant studies, and reviews were searched till November 2021. Results were pooled using random-effects meta-analysis or narrative synthesis.

RESULTS

A total of 44 RCTs were included. This review showed a significant effect of peer teaching on procedural skills improvement and a comparable effect on theoretical knowledge and resuscitation skills acquisition compared to the conventional teaching method. Near-peer teaching seemed to be the most effective method for skill improvement. Subgroup analysis showed no significant differences between peer teaching and conventional teaching groups (e.g., expert/faculty teaching, self-study or lectures).

CONCLUSIONS

Peer teaching seems to be a promising teaching and learning strategy in health professions education, positively affecting theoretical knowledge and procedural skills. Future research should explore the effect of peer teaching in developing countries to provide a comprehensive picture of peer teaching.

Psychomotor abilities in diagnostic upper gastrointestinal endoscopy derived from procedural task analysis techniques and expert review

BACKGROUND

Any prediction of a person's ability to succeed in a motor skill depends on the detection and accurate measurement of the basic abilities for the performance of that skill. Task analysis is needed to determine the psychomotor skills and abilities required to perform an action. This study aimed to determine the components of psychomotor abilities for diagnostic upper gastrointestinal (GI) endoscopy through procedural task analysis (PTA) and expert review.

MATERIAL AND METHODS

A multisource, multimethod task analysis was conducted in six metropolitan teaching hospitals affiliated with the adult gastroenterology and hepatology training centers in the Islamic Republic of Iran in 2019. Observation, video-recording, and think-aloud protocols were used while diagnostic upper GI endoscopy was performed. To confirm the accuracy of the PTA, the incorporated the views of the adult gastroenterology and hepatology subspecialty experts through the checklist of PTA assessment criteria. Finally, to determine the psychomotor abilities for each stage of the procedure, the study incorporated a panel of experts from occupational therapy, physical education, physical medicine, and adult gastroenterology and hepatology subspecialty.

RESULTS

Of the 15 psychomotor abilities examined, 11 were determined for upper GI endoscopy procedure, of which six cases (including visuospatial and perceptual abilities, hand-eye coordination, multilimb coordination, finger dexterity, arm-hand steadiness, and manual dexterity) were the most frequent.

CONCLUSIONS

PTA techniques and subsequent expert review were used to identify the components of psychomotor abilities for diagnostic upper GI endoscopy. It is suggested that PTA is performed for other procedures, and after psychomotor abilities are specified, proportional tests are developed.

Video review for measuring and improving skill in urological surgery

Interest is growing within the urological surgery community for objective assessments of technical skill. Surgical video review relies on the use of objective assessment tools to evaluate both global and procedure-specific skill. These evaluations provide structured feedback to surgeons with the aim of improving technique, which has been associated with patient outcomes. Currently, skill assessments can be performed by using expert peer-review, crowdsourcing or computer-based methods. Given the relationship between skill and patient outcomes, surgeons might be required in the future to provide empirical evidence of their technical skill for certification, employment, credentialing and quality improvement. Interventions such as coaching and skills workshops incorporating video review might help surgeons improve their skill, with the ultimate goal of improving patient outcomes.

Advances from the Office of Naval Research STEM Grand Challenge: expanding the boundaries of intelligent tutoring systems

This special issue presents evaluations of four intelligent tutoring systems. These systems were funded under the Office of Naval Research's STEM Grand Challenge for intelligent tutoring systems. The systems each represent aspects of how ITS can address STEM education or how aspects of multiple systems can be integrated to support STEM education. The selected papers also provide empirical evidence for the effectiveness of each system. The current paper provides an overview of the Office of Naval Research STEM Grand Challenge program, the systems funded under the program, and summaries of the articles within this special issue.
