Evaluates the effectiveness of safety illustrations in enhancing safety awareness among students, suggesting potential improvements in teaching methods.
Key Points
The research aims to assess the usefulness of unsafe and safe illustrations in safety instruction for scientific experiments.
Developed unsafe illustrations depicting unsafe situations with gas burners and safe illustrations showing proper safety preparations.
Conducted 'Unsafe Detection Test' using only unsafe illustrations and 'Safety Confirmation Mistake Finding' using both unsafe and safe illustrations.
Involved 194 university students from an education faculty, 88 university students from Thailand, and 139 first-year middle school students in the evaluation.
Analyzed results using a one-parameter logistic model from item response theory.
The 'Unsafe Detection Test' demonstrated strong discriminatory ability, especially identifying students with below-average capability.
Significant differences in ability values were found among the groups, with middle school students performing best and Thai university students performing lowest.
More than half of the participants correctly identified all unsafe locations in the 'Safety Confirmation Mistake Finding,' highlighting the materials' potential to unify safety instruction.
