Description¶

An instructional element in which first-year pre-service teachers in five small groups worked through an ill-structured, real-life problem scenario about children drinking corrosive substances over five sessions: analysing the scenario, listing key issues, defining the problem state, forming and revising hypotheses, deciding on the best solution, and presenting a report. The article states "The teaching of the acid-base topic was presented in five sessions through the PBL in the experimental group", with the researcher acting as facilitator who guided "with questions without giving any information".

Design Implications¶

Context¶

Requirements¶

Ill-structured problems reflecting real life, presented through scenarios, selected as critical to PBL success
Small-group learning arrangements with active participation of each student

Constraints¶

Implemented with first-year pre-service teachers newly acquainted with the approach, in the acid-base chemistry topic only

Target Learners¶

first-year pre-service science teachers

Learning Goals¶

critical thinking disposition
perception of problem-solving ability
acid-base chemistry content

Claims¶

Problem Based Learning
