本研究旨在了解職前華語文教師學習外語的歷程、語言學習信念與教學信念，屬質性個案研究。對象為華語文教學研究所四位台籍研究生，聚焦於外語學習歷程、外語學習信念、外語教學信念三大主軸，以深度訪談作為資料收集方法。訪談內容及範圍主要參考了Horwitz（1985）語言學習信念研究的BALLI 模式以及Johnson（1992）與張碧玲（2000）設計的語言教師教學信念問卷。研究發現包括：（一）不同時期的外語學習經歷對個案職前教師的學習及教學信念起了「學徒式的觀察」、信念的轉變及「濾鏡」等作用。（二）透過對個案的學習及教學信念探討，可以看到信念具有多層次的特質。而其中較整體面向的信念與較個別層次的信念，呈現了相互支持、矛盾等關係。（三）教學信念隨著背後所隱藏的動機不同，不能以因果關係作解釋。（四）個案教師基於不同的學習經歷、學習信念及教學信念，在教學上建構了與社會文化情境相關，同時也具有個人意義的教學理論。最後建議華語文師資教育應提供機會讓職前教師了解自我語言學習及教學信念，以及更多教學實務的機會，以讓他們在教學行動中反思，也在反思中進行教學。華語文教師本身亦可以利用自我的外語學習經驗作為反思的工具，時時保持成長的動機與內省的能力。此外，華語文教師也應對教學現場及環境文化等因素有所知覺，這樣才能促進有效的教學。 / This qualitative case study aims to understand the TCSL ( Teaching Chinese as a Second language ) pre-service teachers’ foreign language learning experience, language learning beliefs, and teaching beliefs. The participants are four Taiwanese postgraduate students from the department of TCSL in a university in northern Taiwan. The study focus on three aspects: foreign language learning experience, language learning beliefs, and teaching beliefs. In-depth interviews are conducted as the data collection method, informed by Horwitz’s (1985) BALLI model as well as Johnson (1992) and Zhang (2000). The findings include that (1) the four pre-service TCSL teachers’ foreign language learning experiences, serving as a filter, afford “apprenticeship of observation” which leads to changes in beliefs, and (2)beliefs are multilayered, involving both supportive and contradictory relationships. (3) Teaching beliefs are not necessarily consistent with each other because of different intentions lying behind. It is difficult to regard them as having a simple cause-and-effect relation. (4) Based on different learning experiences, learning and teaching beliefs, the four pre-service teachers construct their own personal theories toward teaching, which are not only socially relevant but also personally meaningful. Finally, the study suggests that language teacher education needs to provide sufficient opportunities for pre-service teachers to understand their own learning and teaching beliefs. It is also necessary to provide opportunities to engage them in authentic teaching contexts so that they could reflect on their teaching beliefs in real-world pratice. TCSL teachers need to be encouraged to use their own learning experiences as a reflective tool to sustain their passions for teaching.

本研究旨在探討如何設計以建構主義為基礎的專題導向式VR學習環境，並進一步藉由教學實驗探討運用此VR學習環境能否提升學童的學習效果，以及配合「配對合作」、「引導輔助」策略之應用，是否能提升VR學習環境輔助學習之效果。最後，則藉由晤談之分析，瞭解學童經過教學後仍存在哪些錯誤概念，並藉由不同學習環境及不同學習成就學童心理模式之比較，進一步推論影響學童概念之因素，期能提供教學者及後續研究者之參考。 本研究兼採發展學習軟體、準實驗研究法、問卷調查法及晤談法。首先設計並製作「地球的運動VR學習環境」。並選取台南市進學國小三個班級125名學童為對象，進行兩週之教學實驗。隨後進行紙筆測驗立即後測，並於四週後進行延宕後測。此外，在教學後依據學習成就及學習環境，分別選取12名學童參與晤談，以瞭解其心理模式。根據研究所獲得的資料，本研究之主要結論如下： 1. 本研究之VR學習環境有助於學童地球的運動相關概念之學習，然而仍有部分設計未達理想。整體而言，建構式虛擬實境學習環境之設計是值得發展的方向。 2. VR學習環境配合引導策略之應用，有助於學童之立即學習，對於問題層次較為抽象的專題報告，也有較好的效果。但在保留學習以及問題架構較明顯的專題報告中，是否給予輔助則無明顯差異。 3. 在地球的運動VR學習環境中，配對學習的效果並未優於個別學習。同時也沒有證據顯示配對學習的過程中，產生增進學習效果的互動過程。 4. 在VR學習環境中，採自由探索方式的學童有較正向的「學習經驗」和「互動經驗」。 5. 不同學習成就的學童其地球的運動相關概念有著極大的差異，一些容易受到直覺觀念影響的錯誤觀念，即使經過教學也很難改變。 6. 課本平面教材在傳達具有空間性質的概念時，易使學童誤解，有必要發展3D空間性質的教材。 根據研究結果，本研究提出建議，以供教育行政單位、國小自然科教師、電腦輔助教學軟體發展者以及未來相關研究之參考。 / The purposes of this dissertation were (1) to design and develop an innovative VR-based learning environment to teach "the motion of the earth" for the 6th grade students, (2) to investigate the effects after two weeks' instruction of VR-based learning environment on students’ learning achievements, which include different cognitive levels and different content areas, (3) to investigate the effects of cooperative dyads and provide guidance within the VR-based learning environment, (4) to analyze what factors may influence on the conceptual knowledge about the earth for sixth graders through interviews. Research approaches of this study included designing a computer-based learning environment, quasi-experiment, questionnaire survey and structured interview. The VR-based learning environment was designed through the processes of literature review, objective analysis, and content analysis. The evaluation of the VR learning environment was conducted through questionnaire surveying 12 experts and 76 students of the 6th grade to elicit their general opinions. This study employed quasi-experimental design to experiment on 3 classes of 125 students from Tainan Jying-Shyue elementary school. Two classes participated in VR learning environment. The members of the two classes were grouped by heterogeneous mixed-ability dyads or individual learning. The members of one of the VR groups learned through the guidance of worksheets; the students of the other VR group explored the environment by themselves. The third class was a control group whose members learned in traditional model based learning environment. After two weeks' instruction, all subjects accepted the test of the unit of "the motion of the earth" and retest after 4 weeks. 12 subjects attending interviews were selected from 125 students by different test achievements and different groups for the analytic framework. Through the design and evaluation of the VR world and the results from quantitative measure and interview data, the results were as follows: 1. We were gaining insights into the virtual reality's potential and limitations for learning. Constructivist VR-based learning environment is a new direction in the future. 2. Students learning by VR learning environment through guidance performed significantly better on the posttest than the other groups. Whether provided guidance or not, students learning by VR outperformed on test after 4 weeks than traditional learning environment. 3. There were no interaction effects between cooperative dyads and other factors. Cooperative dyads had no effect on test achievement in this study. 4. Students exploring the VR environment by themselves had more positive " learning experience" and "interactive experience" toward the environment than those learned through guidance. 5. Students with different achievement levels held extremely different mental models of the earth. The native conceptual knowledge of the earth was difficult to replace even after instruction. 6. The incorrect mental models concerned 3D concepts held by students were ineffectively corrected by the 2D textbooks. Based on the results of the study, recommendations are then made for related educational administration institution, researchers, instructional designers and elementary teachers.

近年來全球學習華語文蔚為風潮，且隨著資通訊科技和網路快速發展，華語文教學更逐漸向「數位學習」發展。臺灣僑務委員會為提供海外華僑及外籍人士學習華語文，設立「全球華文網」，該網站至2011年為止已突破四千萬的瀏覽人次，使用者眾。本研究即以「全球華文網」為研究個案，旨在探討該網站的優使性，進而歸納網站的優勢和尚待改進之處。希望透過本研究了解華語文教學網站使用者平日需求，及理想的網站應具備哪些功能，對未來建置類似的華語文教學網站時有所助益。 本研究之研究目的可分為以下四項：(一)探討華語文教學網站的內容和網站使用者需求。(二)探討優使性評估定義與優使性測試方法。(三)探討華語文教學網站之優使性及使用者滿意度。(四)分析使用者優使性評估結果，找出網站缺失與改善方向，歸納建議作為未來建置華語教學網站之參考。 本研究採用深度訪談、優使性測試和優使性問卷調查三種研究方式，研究對象為華語文教學學位學程博碩士生及華語文教學學分學程大學生二者。透過實證研究得出以下五點結論：(一)華語文教學課程修習者常使用的網站可分為三類：資料查找、教學輔助、提供相關資訊；(二)使用者使用教學網站通常是任務導向；(三)使用者不滿意「全球華文網」之優使性；(四)「全球華文網」亟待加強網站之分類與名稱、資源整合、檢索功能三者；(五)使用者對「全球華文網」抱持正面且期待的態度。 根據以上結論，本研究也提出建議，希望作為建置類似網站時之參考。首先網站應從使用者的角度出發，思考如何給予最簡單有效的功能，如教學網站在建立前應先釐清建置目的和使用對象，才能進一步提供相對應之資料；網站的選單名稱應易於理解，各項資源應給予簡單說明；教學網站可就使用者之身分不同提供其相對應的使用介面和資源，以上各項功能用以幫助使用者節省摸索網站的時間。此外，網站也應定期進行使用者滿意度調查以及優使性評估，使用者提供的寶貴意見是網站改進的依據，而透過優使性測試，則能夠讓網站建置人員了解使用者操作的實際情形，彌平雙方的認知差距。定期的評鑑能讓網站了解優缺並即時改善和加強功能，以符合使用者的需求。
