本文作者鑑於科學教育在大學通識教育上，應扮演教育大學生成為當下及未來科技化及民主化課程的公民社會之理性知識分子，經由探討美國及臺灣中小學科學教育目標的演化，進而建構大學通識教育中科學園目標，並探討科學(Science)／技學(Technology)／社會(Society)科學教育理念的內涵。其目的在於提出議題導向模式(IOM)的科學教學模式作為達成科學課程目標的可行策略，供學者們參考及批判，藉以達成大學通識教育中科學教學應扮演的教育功能。

In terms of the significance of scientific learning in general college education, the author’s ideology is that the teaching of science should play a role in educating college graduates as rational intellectuals in the science and technology-oriented present, as well as the near future. Therefore, the evolution of goals in science education both in the United States and Taiwan, at the pre-tertiary level, were first discussed, followed by an introduction and elaboration of the essence and educational implications of the Science / Technology /Society (STS) rationale. Lastly, an issue oriented model (IMO) was proposed as one of the strategies for teaching science in college, in helping college students to develop multi-dimensional science literacy. This researcher hopes the IMO will be implemented in the classroom context and critiqued in terms of student achievement and feed back.
