本論文旨在探討九年一貫課程實施後，對於學生在高中學習三角函數所造成的影響，並根據研究結果提出建議，作為教育機關修訂高中課程綱要以及後續研究之參考。 本研究透過內容分析、問卷調查以及訪談之方式收集資料。分析的資料包括九年一貫課程之相關實務現況文件；在調查部分，以自編之「三角函數學習現況調查研究試卷（前測）」、「三角函數學習現況調查研究試卷（後測）」以及「九年一貫後高中生學習三角函數現況之教師意見調查訪問大綱」為研究工具，藉以瞭解學生的先備知識、學習成就以及教師的看法。問卷與訪問調查對象為台灣北部地區4所高中的94學年度高一學生及該班任課教師。從調查資料的整理過程中，歸納九年一貫課程實施後，高中生學習三角函數單元現況的差異性，以及教師觀點中造成此差異性之原因，並進一步提出相關改善的建議。期望本研究對於高中課程綱要的修訂提供有益之參考。 The purpose of the research is to investigate the influence of students learning trigonometry in senior high school after implementing Grade 1-9 Curriculum. And we propose the suggestion according to the result of study as reference to revise the curriculum guidelines of senior high school and follow-up study of the educational authorities. We adopted the ways of content analysis, questionnaire survey and opinion interview to collect the raw data. The analysed materials include the document practically relevant to situation of Grade 1-9 Curriculum. With regards to the questionnaire and interview aspects, we employed those made up by ourselves "The Questionnaire of trigonometry study present situation (pre-test)", "The Questionnaire of trigonometry study present situation (post-test)" and "the outline of opinion interview to teachers about trigonometry study present situation after implementing Grade 1-9 Curriculum" for study tools, for understanding the advanced knowledge and studying achievements of students and the opinions of teachers. The subjects of questionnaire and interview are the first-year students of senior high school in northern Taiwan in 2005 and their mathematics teachers. From the the survey materials, we sum up the differences of trigonometry study situation of senior high school student and the cause of the situation in teachers' points of view, and propose relevant improved suggestions further. We expect this research to offer beneficial reference to the revision of the course.
