線上繪圖計算機Desmos融入國中學習障礙學生二次函數教學之成效研究

Use of Online Desmos Graphing Calculator to Improving the Quadratic Function Learning Outcomes Among Junior High School Students With Learning Disabilities

本研究旨在探討透過線上繪圖計算機Desmos融入國中學習障礙學生二次函數教學成效。研究以臺北市兩名國中九年級學習障礙學生為研究對象，採用單一受試實驗研究法的跨受試多探試設計。實驗設計分為三個階段，即基線期、介入期及保留期。實驗期間以研究者編製之二次函數圖形課程為內容，進行為期3周的課程。研究發現繪圖計算機Desmos融入二次函數圖形教學對於學習障礙學生有立即及保留的學習效果，這兩位學生在未使用繪圖計算機Desmos的基線期階段其答題的平均正確率為38.3%和40%，到了開始使用繪圖計算機Desmos的介入期階段其答題的平均正確率為84%和70%，使用繪圖計算機Desmos除了能增加答題正確率並能提升其學習態度，使他們學習更加主動、有自信。

This study investigated the effectiveness of Desmos graphing calculator in improving the quadratic function learning outcomes of junior high school students with learning disabilities. A between-subject multiple probe design, which is one of the single-subject research approach, was conducted on 2 ninth grade students with learning disabilities at a junior high school in Taipei. The experiment consisted of 3 stages: baseline, intervention, and retention. A 3-week quadratic function graphics course developed by the investigator was provided, revealing that incorporating Desmos in quadratic function graphics teaching produced immediate and retained learning effects among the students. The average correct rates of these two students were 38.3% and 40% in the baseline period when they did not use Desmos, and their average correct rates were 84% and 70% in the intervention period after they started using Desmos. Using Desmos can not only increase the correct rate of test questions, but also improved their learning attitudes; specifically, the students learned more proactively and confidently.
