| 中文摘要 | 本文旨在了解四技科大學生對化學實驗藥品使用相關安全衛生概念之認知與差異,以供未來大一化學相關實驗課程教學參考改進之用。研究對象涵蓋南部某科技大學環安、職安、醫技、食營、食科一、二年級學生共400人。研究工具為自行發展之紙筆測驗,並運用百分比統計、t-檢定、單因子變異數分析等統計方法進行資料分析。評量內容包括一般知識、專業常識、分類概念、使用概念、標籤概念等,總計有15題。主要研究發現如下:(1)缺乏廢棄物混合棄置的知識。(2)對於化學藥品酸鹼性的判斷能力不足。(3)對於化學藥品是有機物或無機物的分辨能力不佳。(4)化學藥品圖樣的辨識能力不夠。(5)整體表現上二年級優於一年級,且達顯著差異水準(p<.001)。(6)性別方面男生的表現各年級均優於女生,但未達顯著差異水準。(7)除了醫技系-食營系(p=.030)與醫技系-食科系(p=.010)有顯著差異之外,其他各系之間並沒有顯著差異。 |
| 英文摘要 | The purpose of this study was to explore the cognitive conception of chemical usage in 4-Year Universities, and to find the misconceptions and the cognitive difference among them. The results would be helpful for the experimental curriculum design and teaching. The subjects were undergraduates who were studying in the departments of Safety Health and Environmental Engineering, Occupation Safety and Health, Food Nutrition, Medical Technology, Food Science & Technology of southern Taiwan area. There were totally 400 students completing the test. The research tool was a self-designed test paper. Collected data were analyzed by statistical measures of percentage statistics, T-test and One-Way ANOVA. This test consisted of five main topics: general knowledge, specialized knowledge, the concept of classified chemicals, the concept of chemical use, and the concept of chemical labels. The main findings of this paper were summarized in the following list: 1) Students lacked the knowledge about how to treat hazardous wastes, 2) students were unable to identify whether a chemical is an acid or base, 3) students couldn't distinguish between organic or inorganic compounds, 4) the capability to simply identified a chemicals by its label was clearly inadequate, 5) the total scores of sophomores and in five topics were significant difference (p<0.001), and the sophomores was better than freshmen. 6) In addition, the scores indicate that the boys had a greater degree of understanding of chemical usage than the girls do. But, the difference among them was not apparent. 7) There were significant difference between the departments of Medical Technology and Food Nutrition (p=0.010), also between Medical Technology and Food Science & Technology (p=0.030). The differences among the other departments were not apparent. |
