Understanding Of Size And Scale And Order-Of-Magnitude Reasoning In Secondary Science: A Teaching Experiment With Worked Examples As Educational Scaffold
Understanding size and scale (USS) and order-of-magnitude reasoning (OMR) are critical for scientific literacy. This study examines an educational approach to enhance these skills in high school science, considering the cognitive prerequisites and challenges. It explores worked examples (WEs) as an effective method to teach USS and OMR, comparing their impact on students' knowledge and transfer abilities with conventional tasks in a quasi-experimental study. The results indicate significant improvements in procedural and conceptual knowledge, effective for diverse learners regardless of prior knowledge.
