本研究主要開發STS活動單元“植物色素”和“天然清潔劑”之學習情景／評量策略，並以「實作」為活動重點的教學活動設計。在此等活動單元中，所採用的教學策略有：1.腦力激盪，2.小組合作學習，3.師生共同合作學習，4.班級討論，5.做抉擇，6.解決問題，7.實驗研究，8.口頭報告，9.實驗流程設計，10.活動概念圖。
在活動的設計中儘量讓學生保持高度的興趣，並且能將所學到的化學概念和技能轉移到新的情境中。在活動中所使用的評量策略包括：1.小組及個人表現：學生間的全作程度、參與度及發言次數。2.學科紙筆測驗。3.學習層次評量。活動後學生均表示喜歡這樣的教學活動。在第一次“植物色素”實驗活動單元中參與人數為22人，幾乎所有學生對相關知識之學科成績都有明顯的進步，學科知識測驗成績有20人通過（90.9%）；學科知識測驗成績與參與度正相關為87%；學習層次有17人通過（77.27%）。在第二次“植物色素”實驗活動單元中參與人數為16人，學科知識測驗成績16人通過（100％）；學科知識測驗成績與參與度正相關為70%；學習層次有11人通過（68.75%）。在“天然清潔劑”實驗活動中參與人數為16人，其第一單元活動學科知識測驗成績有12人通過（75%）；第二單元活動學科知識測驗成績有15人通過（93.75%）；在整體活動中，學習層次有11人通過（68.75%）。第一單元活動學科知識測驗成績與參與度正相關為72%；第二單元活動學科知識測驗成績與參與度正相關為70%。

The thesis works on two STS modules, "Pigment of Plants" and "Natural Cleaner", to develop the learning situation/strategies of evaluation, and "putting into practice" is the main part of the design of the teaching activities.The teaching strategies ued are:1.)brainstorming; 2.)group cooperative learning; 3.)cooperation between teachers and students; 4.)discussion; 5.)decision making; 6.)problem-solving; 7.)study on the experiment; 8.)oral report; 9.)designing of experimental procedure; 10.)designing of activity concept map. Through the whole activities, tried to keep the students in high interest, and made what they had learned on chemistry, both concepts and skills, transferred to a new condition. The strategies of evaluation used in the activities were 1.)the performance of each group and each individual: cooperation, participation, and times of speaking; 2.)achievement in subject matter knowledge was assessed with paper-pencil tests; 3.)level of learning. After the activities, the students expressed that they like such teaching activities. In the first part of "Pigment of Plants" STS experimental activity, the total participants were 22, and almost all the students had obvious progress of their grades on the subjects of relative knowledge. There were 20 people passed the subject matter knowledge test, at the of 90.9%; there was strong positive correlation, expressed by percentage consistency, between degree of participation and the grades of written test(87%); 17 people passed the learning level, at the rate of 77.27%.In the second part of "Pingment of Plants" STS experimental activity, the total participants were 16, and all of them passed the subject matter knowledge test, at the rate of 100%; there was strong positive correlation, expressed by percentage consistency, between degree of participation and the grades of written test (70%); 1l people passed the learning level, at the rate of 68.75% .In the first part of "Natural Cleaner" STS experimental activity, the total participants were 16, and 12 people passed the subject matter knowledge test, at the rate of 75%; there was strong positive correlation, expressed by percentage consistency, between degree of participation and the grades of written test(72%).In the second part of "Natural Cleaner" STS experimental activity, there were 15 people passed the subject matter knowledge test, at the rate of 93.75%; there was strong poistive correlation, expressed by percentage consistency, between degree of participation and the grades of written test(70%), There were total 11 people passed the learning level of "Natural Cleaner" STS experimental activity, at the rate of 68.75%.
