[[alternative]]A Study on The Mathematical Learning Effectiveness of Information Technology Integrated Into Teaching for Student Example of ＂Quadratic Function＂

[[abstract]] 本研究主要應用資訊教學軟體融入教學方式，來探討國中生目前在課堂上學習二次函數之學習情形，試著利用資訊科技融入教學之電腦動態幾何互動軟體當作教學媒介，研究學生在數學學習成效上有何影響。 本研究採用準實驗研究法，以嘉義縣某國中三年級兩個班級共59位學生為實驗之研究對象，以一班29人為實驗組，採用資訊融入教學模式，實驗教學中所使用軟體為GSP動態幾何軟體(Geometer's Sketchpad)；另一班30人為控制組，採用傳統教學模式，進行實驗教學12節課。待實驗結束後，再利用SPSS ( Statistics Package for Social Science ) 統計軟體做為分析工具，分析受試者在學習成效中的差異情形，最後歸納出本研究的實驗結論有：一、在資訊融入教學下，學生在學習數學二次函數時，學習成效相較於傳統非資訊軟體方式有明顯的進步。二、在實驗過程中發現，學習成效之所以有明顯得進步，原因是資訊融入教學有助於學生深入瞭解二次函數幾何之意義與概念，讓學生對數學更產生興趣且有提高學生學習數學技能之精熟度，並增強概念圖像表徵。[[abstract]] The purpose of this study is to apply information technology in teaching. Using information technology assisted teaching with Dynamic Geometer's Sketchpad (GSP for abbrev.) as teaching media to evaluate learning effectiveness on quadratic function (QF) by 59 ninth-grade students of junior high schools in Chiayi County. A quasi-experimental design was used with 59 students of the ninth graders in Chiayi County, and 12 lessons of teaching experiments were conducted. One class was assigned as the GSP experimental group while the other one was traditional teaching control group. ＂The Mathematics Language Attitude Survey ＂, ＂The Mathematics Learning Sheet ＂ , and ＂The Infusing Information Technology Into Mathematics Attitude Survey ＂ were adopted as instruments of analysis. The main findings of this study can be summarized as follows: 1. The learning effectiveness on quadratic function of the experimental group was significantly higher than the control group. 2. Integrating information technology into teaching not only helped the students understand quadratic function's key concepts and motivate their learning but also assist them to increase their proficiencies in acquiring mathematical skills and enhance the concept of iconic reprentations. As a result , the learning effectiveness of the experimental group was significantly improved
