本研究旨在發展評量策略於國中數學三角形的外心、內心與重心單元,探討QR Code解題範例對學習動機與學習成效的影響。研究對象為國中三年級兩班學生,分成一班實驗組33人,一班控制組35人,實驗組在形成性評量後使用QR Code解題範例讓學生自主學習,控制組則在形成性評量後進行傳統教學。三週後進行學習成效後測和動機問卷。 經由研究結果發現: 1.使用QR Code解題範例融入教學的學習成效優於傳統教學。 2.不管何種教學模式下,不同學習能力水準學生間其學習成效有顯著差異。 3.高分組與中分組的學習成效並不因為教學方法的不同而有顯著性差異;但低分組在不同教學法下,其學習成效有顯著性差異存在。 4. QR Code解題範例能激發學生的學習動機。 結論,導入QR Code解題範例可提升學生的學習成效與學習動機。在學習成就方面,對低分組的學生是有幫助的。 最後根據以上結果,研究者針對QR Code解題範例及未來研究提出建議。
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.
