基於QR Code解題範例發展評量策略以增強學習成效：以國中數學三角形的外心、內心與重心為例

Abstract

The purpose of this study was to investigate the influence of learning motivation and effectiveness on different assessment strategies of junior high school students after integrating QR Code solving examples into the unit of circumcenter, incenter and centroid of a triangle. The participants of this study were grade nine students. They were separated into two groups: One was experimental group, and the other was controlled group. There were thirty-three students in experimental group. There were thirty-five students in controlled group. The students in experimental group used QR Code solving examples, and the other group proceeded traditional teaching after the formative assessment. Three weeks later, they were asked to finish learning motivation and effectiveness questionnaire posttests. The results are as follows: 1. Integrating QR Code solving examples into learning materials is better than traditional teaching in learning effectiveness. 2. Students with different learning abilities, no matter in experimental group or controlled group, there are significant differences in their learning effectiveness. 3. With different teaching methods, there are no significant differences between high-level and middle-level ability of students who have the same learning ability. However, there are significant differences in low -level students. 4. The QR Code solving examples could raise students’ learning motivation. The conclusion is that integrating QR Code solving examples into learning materials can improve students' learning effectiveness and learning motivation. It is helpful for low-level students in learning effectiveness. Finally, suggestions are proposed as references for QR Code solving examples design, QR Code solving examples instruction and future research.
