數學焦慮與自我概念對動機與成就中介效果之探討:以PISA 2003香港資料為例 / The Mediating Effects of Mathematics Anxiety and Self-concept on the Motiviaion and Achievement: The Hong Kong Case of PISA 2003韓珮華, Han, Pei Hua Unknown Date (has links)
近年來,大型資料庫的建制與分析逐漸成為一種教育研究趨勢,本研究即以PISA 2003資料庫為例,目的是建立影響數學成就的結構方程式模型。在評閱相關文獻後,研究者採用內在動機、工具性動機、數學焦慮、自我概念與數學成就等變項,探討之間的影響關係模型。此外,為使本研究所建立的模型具有模型穩定之證據,因此,將有效樣本隨機分割為建模樣本與驗證樣本,進行最終模型的交叉驗證。
據此,本研究首先使用描述性統計以瞭解香港學生的整體表現傾向,其次,透過探索性因素分析確立研究問卷的信效度,最後,以結構方程式模型建立模型並交叉驗證。資料蒐集對象為香港十五歲之在學學生,有效樣本達4,389位。
依據統計分析結果顯示,內在動機與工具性動機對數學成就沒有直接影響效果,但是內在動機與工具性動機透過數學焦慮及自我概念對數學成就產生間接影響,本研究歸納出七點結論茲分述如下:
1.工具性動機較內在動機更為強烈
2.數學焦慮在動機與數學成就間扮演中介變項之性質
3.自我概念在動機與數學成就間扮演中介角色
4.自我概念在數學焦慮與數學成就間扮演中介角色
5.在內在動機、工具性動機與數學焦慮中,工具性動機扮演負向壓抑變項角色
6.在內在動機、工具性動機與自我概念中,工具性動機扮演負向壓抑變項角色
最後,根據研究結果提出各項建議,以供教學實務上及未來研究參考。 / Recently, establishing and analyzing databases becomes a trend in the field of education research. This study took PISA 2003 database as an example to create a psychometric model of factors that influence mathematics achievement. Based on the literature review, the researcher decided to put influential factors, including intrinsic motivation, instrumental motivation, mathematics anxiety, self-concept, and mathematics achievement into the model. Afterwards, through cross-validation the present study had verified the model stability.
In the aspect of statistic analysis, the descriptive static shows HK students’ general learning tendency. Moreover, the exploratory factor analysis confirmed the reliability and validity of the questionnaires. Lastly, the structural equation modeling(SEM) was used to set structural model. The valid samples were 4,389 15-year-old students.
According to the results, intrinsic motivation and instrumental motivation had no direct effect on mathematics achievement and had indirect effect through mathematics anxiety and self-concept. The results were summarized as follows:
1.Students had more instrumental motivation than intrinsic one.
2.Mathematics anxiety was a mediator variable between motivations and mathematics achievement.
3.Self-concept was a mediator variable between intrinsic motivations and mathematics achievement.
4.Self-concept was a mediator variable between mathematics anxiety and mathematics achievement.
5.Instrumental motivation was a negative suppressor variable among intrinsic motivation, instrumental motivation, and mathematics anxiety.
6.Instrumental motivation was a negative suppressor variable among intrinsic motivation, instrumental motivation, and self-concept.
Finally, according to the findings, implications and suggestions for teaching of mathematics and future research were discussed.

大學生生活壓力、解釋風格與情緒幸福感之關係研究 / The relationships among life stress, explanatory style, and emotional well-being of college students.楊晴如, Yang, Ching Ju Unknown Date (has links)
在急速變遷與多元渾沌的現今,如何轉化複雜且遽增的壓力以提升個體本身的幸福感實屬一重要的議題。本研究主要目的在建立生活壓力、解釋風格與情緒幸福感的結構方程式模型,藉以探討之間的影響關係,進而瞭解解釋風格在這關係中所扮演的中介效果。
本研究以兩組各644位政治大學的大學生為研究對象,採問卷調查法施以生活壓力量表、解釋風格量表及情緒幸福感量表,使用的資料分析方法包括:t考驗、單因子變異數分析、因素分析、及結構方程式模型。本研究以第一組樣本探究不同性別與不同年級在研究變項上的差異,接著,經建構與修正模式後提出最終的關係模式,最後,以第二組樣本驗證最終模式的穩定性。主要結果茲分述如下:
一、在背景變項方面:
(一)不同性別與不同年級大學生在「生活壓力」與「解釋風格」上有顯著差 異。
(二)不同性別與不同年級大學生在「情緒幸福感」上未有顯著差異。
二、在結構模式方面:
(一)課業壓力、人際壓力對解釋風格有直接正向效果。
(二)課業壓力、人際壓力對情緒幸福感有直接負向效果。
(三)解釋風格對情緒幸福感有直接負向效果。
(四)人際壓力能直接影響情緒幸福感,也能透過解釋風格間接影響情緒幸福感。
(五)解釋風格在課業壓力與情緒幸福感間扮演完全中介變項的角色。
(六)最終模式的交叉驗證具有模式穩定性。
最後,根據研究結果提出建議,供諮商輔導實務及未來研究參考。 / With the rapid change and the multicultural context of the modern society, how to deal with the complicated and hastily increased stress and to promote people’s well-being is an important issue. The main purpose of this study is to construct the structural equation modeling (SEM) of stress, explanatory style, and emotional well-being. By this way, the researcher can explore the relationship among the three variables, and know the mediator variable of explanatory style.
The participants were two groups of students at National Chengchi University, and each group included 644 college students. The data was collected by questionnaires, including the stress scale, the explanatory style scale, and the emotional well-being scale. Moreover, the data were analyzed by t-test, ANOVA, factor analysis, and SEM. The study, firstly, used the first group to explore the differences of gender and grade, and constructed the final structural model after setting and modifying model. Finally, the researcher used the second group to verify the stability of the model. The main results were summarized as follows:
About the background variables:
1.Students with different gender and grade were
significantly different in the scores of stress and explanatory style.
2.Students with different gender and grade were not significantly different in the scores of emotional well-being.
About the structural model:
1.Academic stress and relationship stress had positive influence on explanatory style directly.
2.Academic stress and relationship stress had negative influence on emotional well-being directly.
3.Explanatory style had negative influence on emotional well-being directly.
4.Relationship stress had influence on emotional well-being directly, and it also affected emotional well-being through explanatory style.
5.Explanatory style was a mediator variable between academic stress and emotional well-being.
6.Through the cross-validation, the final structural model was of model stability.
Finally, based on the findings of the study, the researcher made some practical strategies for counselor and some suggestions for further studies.
