摘要

本研究採質與量的研究法，目的在探討POE教學對國二學生氧化還原單元在學習上的影響。在量的研究上，使用準實驗研究法，藉由不等組前後測實驗設計，進行POE教學實驗五堂課，研究對象為臺中市黎明國中八年級兩個班的學生，分成實驗組37人、控制組34人，每組再區分為高、中、低不同的學習成就群，以比較兩組學生在氧化還原的學習成就、學習態度、學習方法的差異，以便進一步探討POE教學對哪一種成就群的學生有較大的影響。在質的方面，以POE學習單和訪談為作為研究工具，對實驗組蒐集質性的資料，進行歸納、分析和比較，以了解學生對POE教學的感受與評價。
本研究使用的工具為：氧化還原學習成就測驗、自然科學習狀況問卷等。所蒐集之資料以平均數、標準差、共變數分析等統計方法加以分析。研究結果發現如下：
一、POE教學能提升學生氧化還原單元的學習成效。
二、POE教學對高、中、低不同成就群學生的概念保留影響，以增進低分成就群學生的學習概念保留，達顯著差異。
三、POE教學對高、中、低不同成就群男生的學習成效影響，以增進中分群和低分成就群學生的學習成效，達顯著差異。
四、POE教學對高、中、低不同成就群男生的概念保留影響，以增進低分成就群學生的學習概念保留，達顯著差異。
五、POE教學對女生的學習成效及學習概念保留影響，未達顯著差異。
六、POE教學對於學生的學習態度及學習方法沒有顯著提升的效果。
七、實驗組學生對POE教學持正向肯定的態度。
最後根據結果，本研究分別對國中教師及未來研究者提出建議，以供參考。

During the research process, quantitative and qualitative methods were adopted by this study. This study was aimed to explore the effect of using POE Strategies of the learning on the eighth-grade students in junior high school. About quantitative analysis, both quasi-experimental research method and nonequivalent pretest- posttest design were administered to collect data by conducting a five-class POE Strategies experiment in two classes of eighth-grade students at Taichung Municipal Li Ming Junior High School. The participants were divided into the experimental group (37) and the control group (34), and each group was further divided into high, middle and low learning achievement subgroups, which explores the effect of the learning outcome, learning attitude and learning method on these different groups. As for qualitative analysis, data including students' POE learning reports and the researcher's interview transcription from the experimental group were used to analyze and compare in order to investigate the students’reception and evaluation of POE Strategies.
The research tools used included the learning achievement tests about redox concepts and questionnaires. The data collected were processed and analyzed with statistical methods including, mean, standard deviation, and ANCOVA. The results of the research are as follows：
1.Using POE Strategies could enhance the learning outcome of junior high school students on redox concepts.
2.Among the high, middle and low learning achievement groups, POE teaching strategies enhanced the conceptual retention in low learning achievement groups to a statistically significant level.
3.Among the high, middle and low learning achievement boy groups, POE teaching strategies enhanced the learning outcome in middle and low learning achievement boy groups to a statistically significant level.
4.Among the high, middle and low learning achievement boy groups, POE teaching strategies enhanced the conceptual retention in low learning achievement groups to a statistically significant level.
5.Among the learning achievement girl groups, POE teaching strategies had no significant effect on enhancing girl students'learning outcome and the conceptual retention.
6.POE teaching strategies had no significant effect on enhancing students’learning attitude and learning mehtod.
7.Students in the experimental groups held positive attitude toward POE teaching strategies.
Based on the conclusions, several suggestions were offered to junior high schools teachers and further researchers respectively.
