Short-term effects of problem-based learning curriculum on students' self-directed skills development

Area of Science:

• Medical Education
• Cognitive Science

Background:

• Traditional didactic curricula are common in medical schools.
• Problem-based learning (PBL) is an alternative pedagogical approach.
• The short-term impact of PBL on specific student skills requires investigation.

Purpose of the Study:

• To compare the short-term effects of PBL versus traditional curriculum on medical students' scientific thinking.
• To evaluate the impact of PBL on students' problem-solving abilities.
• To assess the influence of PBL on students' conflict resolution skills.

Main Methods:

• A comparative study was conducted in two Turkish medical schools with differing curricula (PBL vs. traditional).
• Three student groups were assessed: PBL students, and two control groups (traditional curriculum).
• Standardized inventories and questionnaires were administered pre- and post-intervention over 10 months.

Main Results:

• No significant pre-test differences were found in scientific thinking, problem solving, or conflict resolution skills among groups.
• PBL students demonstrated significantly greater improvements in all three assessed skills compared to control groups.
• Control groups showed no significant skill improvement over the study period.

Conclusions:

• Problem-based learning curricula can positively impact students' self-directed skills, including scientific thinking, problem solving, and conflict resolution.
• These positive effects can be observed even within a short academic period.
• PBL may be an effective instructional strategy for developing critical student competencies.
