本研究旨在以基模化電腦影片協助國民小學聽覺障礙學生解多步驟算術文字題。參加研究之聽障受試者共4位:包括接受巡迴輔導服務國民小學普通班聽障生4年級1位,3年級1位,啟聰班4年級聽障生1位,及資源班3年級聽障生1位。研究設計採單一受試研究法進行電腦輔助教學實驗,分為基期、介入期、維持期及類化期4個階段。基期與類化期採紙筆測驗,介入期和維持期均在電腦上進行。 所得的資料以目視分析探討受試者在多步驟算術文字題的解題表現。本研究結果綜合如下: 一、 聽覺障礙學生在經過基模化電腦影片教學之後,能提升多步驟算術文字題的整體分數。 二、 聽覺障礙學生在經過基模化電腦影片教學之後,四位受試者對多步驟算術文字題解題測驗的答題水準,具有維持效果。 三、 聽覺障礙學生在基模化電腦影片教學後的解題歷程有明顯的正向變化,能有效幫助聽覺障礙學生思考及解多步驟算術文字題。 根據研究結果,研究者提出建議,以作為未來教學及研究之參考。
The purpose of this study was using schematic video to help hearing-impaired students solve multi-step arithmetic word problems involving money. The participants were 4 hearing-impaired students: two 4th graders and two 3rd graders. The single subject multiple-probe design across students was employed with 4 phases: base, intervention, maintenance and transfer. Paper and pencil tests were used in base and transfer phases, and computer tests were used in intervention and maintenance tests. The students were found to be interested in the schematic video software and the schemas help them to think and solve multi-step arithmetic word problems.
