父母教養信念與方式經由孩子內在動機資源對孩子成就影響之研究

梅淑鶯, May,Iris Unknown Date (has links)
本研究主要的目的在探討父母教養信念與方式、孩子內在動機資源、以及孩子成就之間的關係,即本研究所假設之「父母教養信念與方式影響孩子成就模式」是否成立。其中父母教養信念與方式是以父母重視學習、父母正向知覺、父母投入、以及父母自我效能為測量變項;孩子內在動機資源是以能力感、自主性、以及連繫性為測量變項;孩子成就是以期末成績、以及老師所評定之五育表現為測量變項。 本研究以雲林縣及台中市共15班的七年級孩子與他們的父母為研究對象。測量工具有三種分別為,測量父母教養信念與方式之「父母教養信念與方式問卷」,測量五育表現的「老師評比問卷」,以及測量孩子內在動機資源的「自我信念領域量表-中文版」。前兩個測量工具為研究者自編,以110份預試問卷,進行選題,建立信、效度,並以正式施測的521個研究樣本考驗問卷之有效性。後者則是譯自學校衡鑑研究工具(Institute for Research and Reform in Education、Inc.、IRRE、1998)的「自我信念領域量表(Beliefs about Self Scale)」。 結構方程模式考驗的結果顯示,「父母教養信念與方式影響孩子成就模式」與觀察資料達到良好適配,表示父母對孩子學習的正向觀感、父母本身認為學習對孩子的重要性、父母參與孩子學習活動的頻率、以及父母認為自己擁有幫助孩子發展的自我效能這四項父母教養信念與方式,能構築成支援性後天環境,除了直接影響孩子成就外,也會經由孩子產生掌握學習活動的能力感、主動參與學習的自主性、以及與環境建立安全連結的連繫性,幫助孩子在學校的表現。 根據逐步迴歸分析,本研究也發現,不論是預測孩子的期末成績是由老師所評定的五育表現,父母認為學習對孩子的重要性、父母對孩子表現的正向知覺、以及孩子所擁有的能力感相對上是較重要的父母教養信念與方式與孩子內在動機資源變項。因此對於七年級孩子的學習,父母較有效介入方式,並非直接的課業教導或監督、安排課後補習或才藝訓練、或對孩子不時的耳提面命,而是秉持重視學習的態度,正向樂觀地看待孩子的表現,這種態度上的潛移默化,孩子就容易建立正向的自我概念或能力感,進而表現得好。 除了上述結果,本研究也提出實務、以及未來研究上的建議,期望能作為家庭與親職教育領域的參考。 / This research is to examine a process model of relations among parental beliefs/practices、child inner resources and child achievement、namely、to validate the proposed 『Model of Influences on Parental Beliefs/Practices and Child achievement』. The parental beliefs/practices are composed of four observed variables: parents』 valuing learning、positive perception、involvement and self-efficacy. The child inner resources includes three observed variables: perceived competence、autonomy and relatedness. The child achievement comprises two observed variables: grade point average (GPA) and school performance. Participants were children in 15 classes of Grade 7 and their parents. Three self-report questionnaires、including 『Parental Beliefs/Practices Questionnaire』,』Teacher Ratings Questionnaire』 and 『Beliefs about Self Scale』 (Institute for Research and Reform in Education、Inc.、1998)、were utilized to measure the observed variables of parental beliefs/practices、child inner resources and child achievement respectively. The former two instruments、designed by the researcher、were established by a process of item selection and testing of reliability and validity based on the data of 110 participants in a pilot study. The factor structure and validity of these two instruments were further validated by 512 participants. The latter one was translated from the Belief about Self Scale (IRRE、1998) of Research Assessment Package for Schools developed by Institute for Research and Reform in Education、Inc. The test result of SEM suggested that the proposed 『Model of Influences on Parental Beliefs/Practices and Child Achievement』 fit the collected data well. That means、besides enhancing children’s achievement directly、all of the four parental beliefs/practices are able to generate a supportive environment to influence the children’s achievement、mediated by child inner resources. By the results of stepwise regression、we found that parents』 valuing learning、parental positive perception and perceived competence are important variables in predicting either GPA or school performance. This finding implied、to children in 7th grade、the effective ways in helping children may not be guiding or monitoring their learning activities、arranging additional training or providing advice、but to emphasize learning and appreciate children’s performance positively. This kind of attitude will enhance children’s positive self-concept or perceived competence so as to improve their performance in school. Besides above results、we raised several advices for parents and school for the sake of parental practices and education. Suggestions were also made for further research.

蕭丞傑, Hsiao, Cheng Chieh Unknown Date (has links)
本研究之目的在於探討線上社群協作與其前置因素之關係,並且檢驗社群投入度之中介效果。首先,本研究應用角色內與角色外行為分類,提出角色內與角色外線上社群協作之類型。其次,依據社會認知理論與社會交換理論,本研究提出線上社群協作之前置因素,包括對個人之結果預期、對社群之結果預期、知覺社群信任、知覺社群規範、知覺社群支持與知覺社群認同。最後,本研究基於投入度觀點,檢驗社群投入度對於線上社群協作及其前置因素之中介效果。 本研究之研究情境為玩家公會社群,本研究自一知名大型多人線上遊戲中收集340份有效問卷進行資料分析與假設檢驗,研究結果顯示:(1) 除社群禮貌外,社群投入度對於社群合作行為、助人行為與運動家精神皆有正向影響;(2) 對個人之結果預期與線上社群協作行為之關係,會受到社群投入度所中介;(3) 對社群之結果預期與線上社群協作行為之關係,會受到社群投入度所中介;(4) 知覺社群信任與線上社群協作行為之關係,會受到社群投入度所中介;(5) 知覺社群規範與線上社群協作行為之關係,會受到社群投入度所中介,但社群規範對於運動家精神亦有直接負向效果;(6) 知覺社群認同與線上社群協作行為之關係,會受到社群投入度所中介,但社群認同亦會直接正向影響社群合作與助人行為;(7) 然而,知覺社群支持與線上社群協作行為之關係,並不會受到社群投入度所中介。針對上述之研究結果,本研究進一步闡述其學術研究意涵、實務管理意涵,以及研究限制與未來研究方向。 / The purpose of this study is to investigate the relationships between online community collaboration and its antecedents by examining the mediating effect of community engagement. First, this study proposes a classification of online community collaboration by following the typology of in-role and extra-role behaviors. Accordingly, this study will further examine some of online community collaboration behaviors, including community cooperation, helping behavior, community courtesy, and sportsmanship. Second, drawing upon social cognitive theory and social exchange theory, this study identifies several antecedents of online community collaboration, including person-relevant outcome expectancy, community-relevant outcome expectancy, perceived community trust, perceived community norms, perceived community support, and perceived community identification. Finally, from the perspective of engagement, this study will examine the mediating effect of community engagement on the proposed model. The research setting of this study is online gaming communities. After collecting 340 valid responses from a famous Massive Multiplayer Online Game (MMOG), our results show that (1) community engagement affects community cooperation, helping behavior and sportsmanship positively, but does not have a significant effect on community courtesy; (2) the relationships between person-relevant outcome expectancy and three online community collaboration behaviors are mediated by community engagement; (3) the relationships between community-relevant outcome expectancy and three online community collaboration behaviors are mediated by community engagement; (4) the relationships between perceived community trust and three online community collaboration behaviors are mediated by community engagement; (5) the relationships between perceived community norms and three online community collaboration behaviors are mediated by community engagement, but perceived community norms also has a direct and negative impact on sportsmanship; (6) the relationships between perceived community identification and three online community collaboration behaviors are mediated by community engagement, but perceived community identification also has direct and positive impacts on community cooperation and helping behavior; (7) the relationships between perceived community support and online community collaboration behaviors are not mediated by community engagement. According to these findings, this study concludes with research implications, managerial implications, research limitations and future research directions.

資訊系統需求擷取之知識互動探討 / A study on knowledge interaction in the process of information system requirement elicitation

黃國華, Huang, Travis K. Unknown Date (has links)
當創新總是發生在不同專業領域的交界之處,團隊成員之間有效的知識互動便成為組織維持其競爭優勢的必要因素,因此為了持續創新,團隊成員必須克服不同專業領域所存在的知識邊界障礙,以便能夠整合團隊成員的知識與專長。在資訊系統的開發過程中,系統分析階段是觀察系統分析人員與使用者知識互動的最佳情境,因此本研究首先探索系統分析情境下影響互動雙方知識分享意願的前因,即創新氣氛與互動雙方的互動投入程度,並檢測這些因素之間的關係及影響。其次,本研究彙整四類邊界物件的內容,即語法的、語意的、實務的與隱喻的邊界物件,探討不同類別的邊界物件之間的關係及對專案創意的影響,並更進一步探究互動雙方的知識分享意願對各類邊界物件的影響。 研究樣本來自258位學生所扮演的系統分析人員及258位業界使用者,研究結果發現創新氣氛會同時影響系統分析人員與使用者的知識分享意願。當系統分析人員的互動投入程度越高,使用者的互動投入程度也會提高。使用者的互動投入程度會正向影響系統分析人員及使用者自身的知識分享意願;但是系統分析人員的互動投入程度卻對使用者的知識分享意願產生直接且負向的影響。 此外,系統分析人員的知識分享意願只對隱喻的邊界物件有正向影響,而使用者的知識分享意願卻對這四類邊界物件皆無顯著影響。在這四類邊界物件之中,只有實務的邊界物件對專案創意具有正向的影響,而隱喻的邊界物件則對於語法的、語意的、實務的邊界物件三者具有正向的影響,因此隱喻的邊界物件可以藉由實務的邊界物件對專案創意產生正向的間接效果。出乎意料之外,語意的邊界物件對專案創意具有負向的影響。在實務方面,本研究建議組織應該藉由增加實務的邊界物件和隱喻的邊界物件,以提高專案創意嶄露的可能性。 / As innovation happens from the boundaries between different specialty domains, effective knowledge interaction among participants has become a competitive necessity for organizations. In order to improve innovation, it is necessary for participants to deal explicitly with the interpretive barriers and further synthesize their expertise. During the development of information system, most knowledge interactions, which are conducted by systems analysts and users, can be observed in the phase of systems analysis. Thus, this study intends to explore not only factors that may affect participants’ intention to share knowledge, but also types of boundary objects in the context of systems analysis. As an innovative organizational climate and participants’ interaction involvement are identified as antecedents of participants’ intention to share knowledge, the relationships among these factors are studied. Besides, while four types of boundary objects are summarized, their effects on project innovativeness are discussed. Then, the influence of participants’ intention to share knowledge on the occurrence of four types of boundary objects was further examined. The results, based on data collected from 258 student analysts and 258 users, indicate that an innovative climate positively and directly influences both systems analysts and users’ intention to share knowledge. While systems analysts’ interaction involvement has a strong influence on users’ interaction involvement, which is measured by responsiveness, perceptiveness and attentiveness, users’ interaction involvement also has positive effects on both systems analysts and users’ intention to share knowledge; unexpectedly, systems analysts’ interaction involvement is negatively related to users’ intention to share knowledge. In addition, while systems analysts’ intention to share knowledge only influences the occurrence of metaphoric boundary objects, users’ intention to share knowledge does not demonstrate any significant effect on four types of boundary objects. Out of syntactic, semantic, pragmatic and metaphoric boundary objects, only pragmatic boundary objects had a strong positive effect on project innovativeness. As metaphoric boundary objects are shown to have positive effects on all other three types of boundary objects, metaphoric boundary object affects project innovativeness indirectly through pragmatic boundary objects. Surprisingly, semantic boundary objects negatively affects project innovativeness, although not very strongly. A practical implication is the possibility of increasing project innovativeness by enhancing both pragmatic boundary objects and metaphoric boundary objects.

曾聖文, TSENG, SHENG-WEN Unknown Date (has links)
中國大陸自「改革開放」以來,在經濟體制和結構上有著急遽的轉變,同時,海峽兩岸的經貿互動與依存程度也愈來愈高。因此,能有效分析中國大陸經濟情勢的政策模型,對於台灣與中國大陸的政策制定者與政策研究分析者而言皆十分重要。可計算一般均衡(Computable General Equilibrium,CGE)模型由於在數據需求的較大彈性及模型結構上的特性,成為中國大陸現今重要的經濟政策模型之一,本研究的目的在於考察、分析中國大陸可計算一般均衡(CGE)模型的研發背景、發展歷程、建模過程、主要政策應用方向及研究結果。   本研究的內容及流程如后:(1)依「歷史研究」、「調查研究」來歸納、分析中國大陸經濟學研究的發展歷程,以及中國大陸可計算一般均衡(CGE)模型的發展歷程;(2)接著依「文獻研究」來分析、分類本研究所蒐集的中國大陸可計算一般均衡(CGE)模型實證文獻(1978年-1998年);(3)接著依「理論研究」來歸納、分析出可計算一般均衡(CGE)模型的發展、基本結構、數據基礎與建模(Modeling);(4)以「可計算一般均衡」(CGE)方法,先依據最新的「1995年度中國投入產出表」,編制出兩張:「中國大陸1995年社會會計矩陣」、「中國大陸1995年金融社會會計矩陣」為模型數據基礎,然後應用中國大陸所研發的兩個可計算一般均衡(CGE)模型(「中國大陸經濟-環境可計算一般均衡模型」、「中國大陸金融可計算一般均衡模型」)的主要結構和方程式,以說明中國大陸可計算一般均衡(CGE)模型的建模過程和政策應用方向及模擬結果。   本研究的研究結果如后:(1)中國大陸經濟學研究的發展、實際經濟情況變化和政策制定需要,導致中國大陸可計算一般均衡(CGE)模型在「改革開放」後的發展可分為「啟蒙研發」和「政策應用」兩個階段;(2)將中國大陸可計算一般均衡(CGE)模型實證文獻(1978年-1998年)有系統地分類出「貿易政策問題」、「能源和環境政策問題」、「財政和稅收問題」、「經濟改革和發展策略問題」、「外來衝擊問題」、「貨幣金融問題」、「社會保險問題」等七類實證文獻;(3)應用兩個中國大陸研發的可計算一般均衡(CGE)模型,來說明建模(Modeling)與數據編制的過程,並延續、拓展相關的政策模擬研究,分析了環境政策(「綠色導向能源政策」,Green-Oriented Energy Policy:2000年-2015年)與匯率政策(「管理浮動匯率政策」,Managed Floating Exchange Rate Policy:1998年)對中國大陸經濟體的影響。 謝 詞 ii 中文提要 iv 英文提要 vi 中文目次 viii 英文目次 ix 表 次 x 圖 次 xi 1. 緒 論 1 1.1 研究動機 1 1.2 研究目的 3 1.3 研究流程與內容 4 2. 文獻探討 5 2.1 中國大陸經濟學研究的發展歷程 5 2.2 中國大陸可計算一般均衡模型的發展 11 2.3 中國大陸可計算一般均衡模型實證文獻回顧 20 3. 可計算一般均衡模型的發展、基本結構、數據基礎與建模 32 3.1 可計算一般均衡模型的概念與發展 32 3.2 可計算一般均衡模型的一般性基本結構 36 3.3 可計算一般均衡模型的數據基礎與校準 40 3.4 可計算一般均衡模型的計算機求解與建模過程 42 4. 中國大陸可計算一般模型之應用(1)─中國大陸經濟-環境可計算一般均衡模型 45 4.1 模型的基本結構 45 4.2 模型方程式 49 4.3 模型的數據基礎與校準 57 4.4 政策應用-中國大陸宏觀調控下環境政策之一般均衡分析 61 5. 中國大陸可計算一般模型之應用(II)─中國大陸金融可計算一般均衡模型 69 5.1 模型的基本結構 69 5.2 模型方程式 71 5.3 模型的數據基礎與校準 73 5.4 政策應用-中國大陸匯率政策之一般均衡分析 78 6. 結 論 83 6.1 本研究主要貢獻 83 6.2 研究限制與建議 84 6.3 後續研究建議 85 參考文獻 86 附錄1. 94 附錄2. 103 / Both the system and structure of Chinese economy have been changed rapidly since the launch of "economic reform and opening to the outside" in Mainland China, and the economic interaction and trade interdependence between Taiwan and Mainland China are intenser and closer. Effective policy analysis models for Chinese economy is very important to the policy makers and policy analysis researcher both in Taiwan and Mainland China. The Computable General Equilibrium (CGE) model has become one of the most important economic policy analysis model because of its characteristic of higher flexibility on benchmark data and structure. The purpose of this study is to review, investigate and analyze the developmental background, developmental progress, modeling procedure, policy simulations and research results.   The brief contents and procedure of this study consist of (1) reviewing on the development of economic research in mainland China and CGE modeling for Chinese economy, (2) reviewing on the literature of CGE models for Chinese economy used on Policy Analysis(1978-1998), (3) reviewing on the development, basic structure, benchmark data and modeling of CGE model, (4) constructing two Chinese Social Accounting Matrix (SAM) tables developed from the most recent 1995 Chinese Input-Output table to be the benchmark data of two CGE models, the "Chinese Economic-Environmental CGE model" and the "Chinese Financial CGE model", which are developed from Chinese government and researchers, and we revise them in this study,(5) applying those two models to show and illustrate the modeling procedure and results of policy simulations of CGE models for Chinese economy.   In conclusion and contribution, it is composed of three parts. (1) The development of CGE model in Mainland China can be divided into two ages, "The Beginning"(1978-1991) and "The Take-off"(1992-), which results from the development of economic research in Mainland China, the rapidly changed economic system and structure of Chinese economy, and government's urgent demands for policy-analysis tools. (2) The literature of CGE models for Chinese economy used on policy analysis from 1978 to 1998 can be classified into seven groups- trade policy, energy and environmental policies, public finance and tax reform policies, economic reform and development strategy, external shocks, monetary and financial policies, and social insurance policy. (3) We apply those two CGE models for Chinese economy to analyze the economic and environmental impacts of environmental policy- " Green-Oriented Energy Policy"(2000-2015) and the economic impacts of the " Managed Floating Exchange Rate Policy"(1998).
