Purpose: Learner engagement is the energy learners exert to remain focused and motivated to learn. The Learner Engagement Instrument (LEI) was developed to measure learner engagement in a short continuing professional development (CPD) activity. The authors validated LEI scores using validity evidence of internal structure and relationships with other variables.

Method: Participants attended 1 of 4 CPD courses (1 in-person, 2 online livestreamed, and 1 either in-person or livestreamed) in 2018, 2020, 2021, and 2022. Confirmatory factor analysis was used to examine model fit for several alternative structural models, separately for each course. The authors also conducted a generalizability study to estimate score reliability. Associations were evaluated between LEI scores and Continuing Medical Education Teaching Effectiveness (CMETE) scores and participant demographics. Statistical methods accounted for repeated measures by participants.

Results: Four hundred fifteen unique participants attended 203 different CPD presentations and completed the LEI 11,567 times. The originally hypothesized 4-domain model of learner engagement (domains: emotional, behavioral, cognitive in-class, cognitive out-of-class) demonstrated best model fit in all 4 courses, with comparative fit index ≥ 0.99, standardized root mean square residual ≤ 0.031, and root mean square error of approximation ≤ 0.047. The reliability for overall scores and domain scores were all acceptable (50-rater G-coefficient ≥ 0.74) except for the cognitive in-class domain (50-rater G-coefficient of 0.55 to 0.66). Findings were similar for both in-person and online delivery modalities. Correlation of LEI scores with teaching effectiveness was confirmed (rho=0.58), and a small correlation was found with participant age (rho=0.19); other associations were small and not statistically significant. Using these findings, we generated a shortened 4-item instrument, the LEI Short Form.

Conclusions: This study confirms a 4-domain model of learner engagement and provides validity evidence that supports using LEI scores to measure learner engagement in both in-person and livestreamed CPD activities.

Problem: Many non-workplace-based assessments do not provide good evidence of a learner's problem representation or ability to provide a rationale for a clinical decision they have made. Exceptions include assessment formats that require resource-intensive administration and scoring. This article reports on research efforts toward building a scalable non-workplace-based assessment format that was specifically developed to capture evidence of a learner's ability to justify a clinical decision.

Approach: The authors developed a 2-step item format called SHARP (SHort Answer, Rationale Provision), referring to the 2 tasks that comprise the item. In collaboration with physician-educators, the authors integrated short-answer questions into a patient medical record-based item starting in October 2021 and arrived at an innovative item format in December 2021. In this format, a test-taker interprets patient medical record data to make a clinical decision, types in their response, and pinpoints medical record details that justify their answers. In January 2022, a total of 177 fourth-year medical students, representing 20 U.S. medical schools, completed 35 SHARP items in a proof-of-concept study.

Outcomes: Primary outcomes were item timing, difficulty, reliability, and scoring ease. There was substantial variability in item difficulty, with the average item answered correctly by 44% of students (range, 4%-76%). The estimated reliability (Cronbach α ) of the set of SHARP items was 0.76 (95% confidence interval, 0.70-0.80). Item scoring is fully automated, minimizing resource requirements.

Next steps: A larger study is planned to gather additional validity evidence about the item format. This study will allow comparisons between performance on SHARP items and other examinations, examination of group differences in performance, and possible use cases for formative assessment. Cognitive interviews are also planned to better understand the thought processes of medical students as they work through the SHARP items.

Purpose: Direct observation (DO) enables assessment of vital competencies, such as clinical skills. Despite national requirement that medical students experience DOs during each clerkship, the frequency, length, quality, and context of these DOs are not well established. This study examines the quality, quantity, and characteristics of DOs obtained during pediatrics clerkships across multiple institutions.

Method: This multimethod study was performed at 6 U.S.-based institutions from March to October 2022. In the qualitative phase, focus groups and/or semistructured interviews were conducted with third-year medical students at the conclusion of pediatrics clerkships. In the quantitative phase, the authors administered an internally developed instrument after focus group discussions or interviews. Qualitative data were analyzed using thematic analysis, and quantitative data were analyzed using anonymous survey responses.

Results: Seventy-three medical students participated in 20 focus groups, and 71 (97.3%) completed the survey. The authors identified 7 themes that were organized into key principles: before, during, and after DO. Most students reported their DOs were conducted primarily by residents (62 [87.3%]) rather than attendings (6 [8.4%]) in inpatient settings. Participants reported daily attending observation of clinical reasoning (38 [53.5%]), communication (39 [54.9%]), and presentation skills (58 [81.7%]). One-third reported they were never observed taking a history by an inpatient attending (23 [32.4%]), and one-quarter reported they were never observed performing a physical exam (18 [25.4%]).

Conclusions: This study revealed that students are not being assessed for performing vital clinical skills in the inpatient setting by attendings as frequently as previously believed. When observers set expectations, create a safe learning environment, and follow up with actionable feedback, medical students perceive the experience as valuable; however, the DO experience is currently suboptimal. Therefore, a high-quality, competency-based clinical education for medical students is necessary to directly drive future patient care by way of a competent physician workforce.

Purpose: To determine whether students' self-reported race/ethnicity and sex were associated with grades earned in 7 core clerkships. A person-centered approach was used to group students based on observed clerkship grade patterns. Predictors of group membership and predictive bias by race/ethnicity and sex were investigated.

Method: Using data from 6 medical student cohorts at Johns Hopkins University School of Medicine (JHUSOM), latent class analysis was used to classify students based on clerkship grades. Multinomial logistic regression was employed to investigate if preclerkship measures and student demographic characteristics predicted clerkship performance-level groups. Marginal effects for United States Medical Licensing Exam (USMLE) Step 1 scores were obtained to assess the predictive validity of the test on group membership by race/ethnicity and sex. Predictive bias was examined by comparing multinomial logistic regression prediction errors across racial/ethnic groups.

Results: Three clerkship performance-level groups emerged from the data: low, middle, and high. Significant predictors of group membership were race/ethnicity, sex, and USMLE Step 1 scores. Black or African American students were more likely (odds ratio [OR] = 4.26) to be low performers than White students. Black or African American (OR = 0.08) and Asian students (OR = 0.41) were less likely to be high performers than White students. Female students (OR = 2.51) were more likely to be high performers than male students. Patterns of prediction errors observed across racial/ethnic groups showed predictive bias when using USMLE Step 1 scores to predict clerkship performance-level groups.

Conclusions: Disparities in clerkship grades associated with race/ethnicity were found among JHUSOM students, which persisted after controlling for USMLE Step 1 scores, sex, and other preclerkship performance measures. Differential predictive validity of USMLE Step 1 exam scores and systematic error predictions by race/ethnicity show predictive bias when using USMLE Step 1 scores to predict clerkship performance across racial/ethnic groups.

Abstract: Trainees (medical students, residents, and fellows) are beginning to make strides in pushing for changes to their education. While there are many examples of successful trainee-led curriculum reform efforts, the path to success remains unclear. To better understand the process of trainee-driven curricular advocacy, the author analyzes this process through the lens of ecological systems theory (EST) not only to provide readers with context for the barriers and facilitators to trainee-driven curricular advocacy but also to further medical education's understanding of the sociopolitical forces influencing the process of trainee-driven curricular advocacy and reform through the lens of the trainee. EST explains how individuals are influenced by a complex web of social and environmental forces. The theory outlines 5 ecological systems of influence: the microsystem, mesosystem, exosystem, macrosystem, and chronosystem. Using EST to explore the process of trainee-driven curricular advocacy therefore clarifies the many layers of influence that trainees must navigate while advocating for curriculum change. The author then draws on this theory and their own experience as a medical student advocating for local and national curriculum reform to develop a model to facilitate trainee-driven curricular advocacy in medical education. The proposed model outlines concrete steps trainees can take while going through the process of curricular advocacy both within their own institutions and on a national level. Through developing this model, the author hopes not only to empower trainees to become agents of change in medical education but also to encourage faculty members and administrators within health professional training programs to support trainees in these efforts.
