中文摘要 | 摘 要 認識維生素化學名稱、功能與缺乏症實屬不易,學生對維生素概念之低落 亦是必然,為使大學生對維生素有進一步的認識,本研究打破傳統講述教學, 利用概念圖之學習活動進行教學。學習者在教師引導之下,進行概念元素的搜 尋及配對,動手剪貼建立概念圖示,在過程中加深學習印象。首先調查研究參 與者對維生素之俗名、化學名、主要功能、缺乏症的理解情形,視為成就測驗 之前測,進行上述實驗處理後,再施以後測及研究者自行發展的投入量表,調 查研究對象參與實驗處理的程度與概況。研究採32 位大三學生單組前後測設 計,經成對樣本t-檢定統計分析,後測得分顯著提升,甚至在三週後的延宕測 驗,也與前測有顯著差異的效果。雖然後測及延宕測驗並無顯著性的差異,但 在維生素之化學名稱及功能概念的獲得上,具有相當不錯的保留度。 |
英文摘要 | Abstract Understanding the chemical terms, function and deficiency of vitamins is not easy. The vitamins concept of students is inevitably insufficient. To promote college students have a deep understanding of vitamins, this study uses hands-on activity to lay the concept map substitution tradition narration teaching. Under the teacher guides, learners search and match the conceptual elements to lay concept map in order to deepen the learning impression. First, the research investigate the understanding situation belongs to study object about common name, chemical term, the major function and deficiency of vitamins by achievement test, the result can be as the pre-test and retest after carrying on the experimental treatment as post-test. Second, the research measure the investment meter which develops by research for evaluate the degrees of study object engaging the experimental treatment. The treatment was studied using a one-group pretest-posttest design including 32 juniors. Using paired samples t-test statistical analysis, the post-test scores of achievement test are significantly improved, even after three weeks delay in the test, the scores are also significant differences compared with the pretest. Although, there were no significant better performance on the final and reservation test, yet, the chemical term and function in the vitamin concept acquisition, has a fairly good degree reservation. |
