Factors affecting pharmacology learning in integrated PBL in diverse medical students: a mixed methods study

INTRODUCTION

Problem-based learning (PBL) was introduced to address passive teaching limitations. However, it is not fully characterised as a teaching modality in pharmacology. The present study investigated the factors affecting pharmacology learning in an integrated PBL-based curriculum in diverse learners.

METHODS

Year 1 undergraduate medical students from two cohorts at St. George's University of London and University of Nicosia, participated. Statistical analysis of pharmacology knowledge scores, at the beginning (pre-test) and end of the academic year (post-test), investigated readiness to benefit from PBL based on diverse student characteristics (educational background, age, gender, country of origin, ethnicity, native language, PBL experience). Focus groups/interviews and a survey investigated aspects of integrated PBL impacting learning in depth.

RESULTS

Pre- and post-test scores were positively correlated. Students with biomedical sciences degrees performed better at the pharmacology pre- and post-tests, while post-graduate degree holders performed better only at the pre-test. Effect size was of moderate magnitude. However, progress in learning (post-test performance after controlling for pre-test scores) was unaffected. Qualitative analysis revealed three major themes: 1) PBL as a learning environment; 2) PBL as a learning environment in pharmacology; and 3) PBL as a learning environment and confidence in prescribing. Under theme one, skill development, knowledge acquisition through collaboration and self-directed learning, group dynamics and preferred teaching methods were discussed. Under theme two, contextual learning, depth of knowledge and material correctness were raised. Under theme 3, students expressed variability in prescribing confidence. They perceived that learning could be improved by better integration, further references earlier on, more lectures and PBL facilitators with greater content expertise. The survey findings were consistent with those from focus groups/interviews.

CONCLUSION

Pharmacology learning in a PBL-based curriculum is facilitated by constructive, collaborative and contextual learning. While baseline pharmacology knowledge may be advantageous, the other aforementioned characteristics studied may not affect readiness to benefit from PBL. However, further instructional scaffolding is needed, for example through further resources, lectures and self-assessment. The results from our study can inform evidence-based curriculum reform to support student learning further. Addressing learning needs could ultimately contribute to reducing medication errors through effective training of future prescribers.

How do medical students differ in their interpersonal needs?

BACKGROUND

Knowing one's interpersonal relationship preferences can be tremendously helpful for medical students' lives. The purpose of this study was to examine the interpersonal needs in medical students.

METHODS

Between 2010 and 2015, a total of 877 students from four Korean medical schools took the Korean version of the Fundamental Interpersonal Relations Orientation - Behaviour (FIRO-B) scale. The FIRO-B results were analyzed by descriptive statistics, frequency, independent t-test, and one-way ANOVA.

RESULTS

The medical students' scores for interpersonal needs were moderate overall, with the highest scores for control (M = 8.63, SD = 3.08), followed by affection (M = 8.14, SD = 4.34), and inclusion (M = 7.81, SD = 4.30). Gender differences showed in three areas: expressed control (male > female, t = 4.137, p < 0.001), wanted affection (male < female, t = -3.148, p = 0.002), and control needs (male > female, t = 2.761, p = 0.006). By school type, differences were shown in expressed control (t = 3.581, p < 0.001), wanted inclusion (t = 2.625, p = 0.009), Inclusion (t = 1.966, p = 0.050), and expressed (t = 2.077, p = 0.038); undergraduate medical college (MC) students' needs were greater than the needs of graduate medical school (MS) students, but for wanted control, the MS students showed greater needs (t = -2.122, p = 0.034).

CONCLUSIONS

There were differences in all categories except for expressed inclusion, wanted control, and control. The FIRO-B is a useful tool for giving insight into students regarding their interpersonal orientations, which will help them to adjust to medical school life. In addition, the FIRO-B can be useful when mentoring and coaching students.
