現今資訊的普及、知識的豐碩,也使得知識日新月異,令人目不暇給。過去常有人戲言:「教師是以過去的知識,教導現在的學生,去適應未來的生活。」教師們所具備的多元知識,若是只隱藏在教師個人身上,對整個學校組織的貢獻是很有限的,所以社群的發展對於學校教育的成效有著不容置疑的價值。若能透過社群發展,讓教師樂於分享個人知識,將可以使教師的知識發揮更高的應用價值。 本研究在探討三需求理論對國小教師社群參與意圖與知識分享意願三者之關係,經蒐集必要資訊,根據相關文獻探討、歸納、整理後,擬定研究架構,並依此架構構面採用問卷調查方式,探求各變項間關係。 研究結果顯示:1.國小教師之成就需求會正向影響其知識分享意願。2.國小教師之權力需求會正向影響其知識分享意願。3.國小教師之成就需求會正向影響其社群參與意圖。4.國小教師之權力需求會正向影響其社群參與意圖。5.國小教師之歸屬需求會正向影響其社群參與意圖。6.國小教師社群參與意圖會正向影響其知識分享意願。7.國小教師之歸屬需求會正向影響其知識分享意願未獲支持。 Nowadays the popularity and diversity of information not only make knowledge change with each passing day but also bring so many things to choose from . If only teachers have a variety of knowledge , it will be limited to contribute to the whole school organization. That’s why the development of the community for effectiveness of school education has unquestionable value . If teachers are willing to share their own knowledge through the development of community , it will make what they know about play a greatly valuable role. The research works on the relation between elementary school teachers and the three theories -----“Three Needs Theory “ , “Community Involvement” and “Knowledge Sharing Willingness .” Through the collection of required information and summarization and organization of the relevant documentation , the research structure can be initially drafted . Then on the basis of the structure , it takes the survey of questionnaires to explore the relation among the variables of the three theories. The following are the results of the study : First , Need for Achievement of elementary school teachers positively affects their knowledge sharing willingness. Second , Need for Power also has a great influence on teachers’ knowledge sharing willingness.Third , Need for Achievement positively has an impact on teachers’ community involvement. Fourth , Need for Power for teachers also plays an important role on their community involvement. Fifth , Need for Affiliation for primary school teachers positively affects their community involvement. Sixth , primary school teachers’ community involvement directly affects their knowledge sharing willingness. Seventh , it isn’t supportable that Need for Affiliation positively affects their knowledge sharing willingness.
