探究國中地球科學的核心知識--從地科教師觀點出發

Abstract

本研究主要針對國中地球科學教師作問卷及訪談,希望就第一線教師的觀點,找出可能是國中生最迫切需要學到的地球科學核心知識,並分析不同背景教師觀點的差異。本研究進而分析現有的國中地科教材及九年一貫綱要,呈現教材及課程的現況,以提供未來教材編輯、修訂之參考。本研究的主要發現如下:(一)國中的地球科學教師們認為與生活相關的環境議題,在國中階段是比較重要的知識(二)教師對地球科學核心知識的看法,不會因為其背景不同而有所差異。(三)九年一貫課程綱要中,地球科學的份量約佔自然領域的30.2%,顯見國中地球科學有益受重視的趨勢。(四)九年一貫課程綱要中,地科內容以環境生態佔39%最多,環境議題似乎越顯重要。(五)目前國中各版本地科教材的份量,以國編版約佔自然科總時數22.8%較符合九年一貫課程綱要,其餘版本都只佔10.3% ~ 13.6%,明顯太少。(六)從晤談結果顯示:目前國中地球科學課程實施的情形,最大的困難應該在於教學時間不足。
This research was conducted through questionnaires and interviews on the junior high school Earth Science teachers. The purpose was to identify the most essential Earth Science core knowledge required of junior high school students from teacher's perspectives. The differences among teachers with different educational background were also investigated. The current were also analysis of l Earth Science curriculum and the new Nine-Year Curriculum of junior high school. The results of the current siuby might provide useful reference for future curriculum development. The major findings of this research are:(1)From teacher's perspective, the most important Earth Science knowledge at the junior high school stage is human-related environmental topics.(2)There are no differences in Earth Science core knowledge among teachers with diverse educational background.(3)Earth Science becomes more prominent in the new Nine -Year Curriculum as it takes up around 30.2% of all nature science subjects.(4)Among all Earth Science topics the environmental eco-system takes up around 39% of the Earth Science curriculum. It indicates the importance of environment related topics in the current curriculum.(5)Only the government-based version of textbook matches the guideline of Nine-year curriculum plan with Earth Science taking up 22.8% of total nature science teaching hours. Other textbook versions suggest only 10.3%~13.6% of teaching hours that are obviously less than the recommendations of the guideline.(6)The main difficulty of current Earth Science curriculum implementation in junior high school might the insufficient instruction hours.
