本研究目的在探討國中學生經過性教育援其性知識、性態度的效果及所使用的性教育教材的適用性情形，並了解學生對此次性教育的評價。 本研究立意取樣台北市南門國中二年級四個班的學生為研究對象兵161人，經隨機分派為實驗組（80人），控制組（81人）採不相等實驗組、控制組設計。兩組學生在性教育前，均接受性知識、性態度問卷前測，經12小時的教學後，對二組學生再施以後測，並使實驗組學生作學習過程評價。所得資料以二因子共變數分析，百分率敘述及x^2考驗進行統計分析，得重要結論和建議如下： 一、在「性知識」總分及「青春期的身體變化」、「兩性角色與關係」分測驗上，接受性教育教學的學生比未接受者，在性知識分數上有增加，達到預期效果。其它分測驗「性教育概念」、「友誼關係」、「負青的性行為」、「婚姻與生育」上，則不論接受性教育與否，測驗分數沒有差別。 二、接受性教育的學生比未接受者在性態度的總分上更正向•性別角色態度上則更符合雙性化，自慰態度上，異性交往態度更健康，且對婚前性行為態度上，更趨保守。另女生在教學後對性教育的態度顯示出更正向和支持。 三、這是一值得教育行政單位推廣的計劃。 四、本研究仍具有其類推的限制，如須有受過性教育訓練之師資，校方的行政支援等。

The experiment group participated in a 12-hour sex education activity. After the intervention, both groups attended a post-test, and the experiment group also did a process evaluation. Using The Two-Factor Analysis of Covariance, Percentile Description and X^2-Test to analyze the data, the conclusions were: 1) The experiment group's scores of the ”Sex knowledge”, ”Physcial Changes in Puberty” and ”Gender Roles and Relationship” were higher than those of the control group. On the other hand, the experiment group's scores of the ”Concepts of Sex Education”, ”Friendship”, ”Responsible Sexual Behavior” and ”Marriage and Fertility” did not differ from those of the control group. 2) The experiment group's attitudes toward the ”Sexual Attitude”, ”Gender Roles”, ”Masturbation”, ”Dating” and ”Premarital Sexual Behavior” were more positive than those of the control group. Additionally, female students' attitudes showed more positive than those of male students. 3) This project could be recommended to the educational departments for giving a trial. 4) This study was limited in generalization, because of the lack of sex education training for teachers and administrative unmatch.
