Description

The article proposes an integrated teaching model centered on a closed-loop "Problem-Learning Objective-Validation" triad for maximizing PBL's impact in EBERs-ISH education. Curriculum design prioritizes "core problems grounded in authentic clinical failures—such as elevated background, weak signals, or false negatives—rather than the direct prescription of standardized protocols"; problems are mapped to explicit learning objectives aligned with technical critical points; and laboratory practice lets students validate their problem-solving hypotheses, "fostering iterative cycles of hypothesis formation, experimental validation, and reflective refinement." The study operationalized PBL through five phases: problem identification, knowledge-gap analysis, independent research, collaborative synthesis, and practical validation with expert feedback.

Design Implications

Context

Requirements

  • Instructors must shift from a "knowledge dispenser" to a "learning facilitator", with faculty development in designing authentic open-ended problems, facilitative questioning, and feedback expertise
  • Minimal resource support remains essential: adequate standardized tissue specimens, comprehensive case repositories with authentic clinical data, and literature access and discussion infrastructure

Constraints

  • The study targeted foundational EBERs-ISH competency development; efficacy of PBL for advanced clinical applications remains unexplored
  • Evidence derives from a single institution with a modest sample, limiting generalizability to resource-limited or community-based settings

Target Learners

  • postgraduate pathology residents and clinical pathology technology trainees

Learning Goals

  • EBERs-ISH theoretical knowledge
  • practical slide preparation and troubleshooting skills
  • higher-order problem-solving and technical reasoning
