本研究採用準實驗設計之「實驗組對照組前測後測設計」，選取臺北市大直高級中學及臺北縣土地市海山高級工業職業學校二年學生為研究驗組；臺北市西松高級中學及臺北縣淡水高級商工職業學校二年度學生為研究的對照組。在教育介入前一週兩組學生分接受前測問卷作為評量實驗效果的基準。實驗組學生接受五週(共十小時)性教育教三定活動，並探討學生對教學的過程評價及心得，而對照組則未托受教學；教學結束後一週，進行後測以評量此性教育教學之效果。 研究結果發高中實驗組學生在「性社會現況之覺察程度」、「性知識」、「性態度」、「採取安全性行為之自我效能」、「同儕社會支持度」及「採取安全性行為之行為意向」之分析結果，均達到顯著差異；而高職實驗組學生在「性社會況之覺察程度」、「性知識」、「性態度」、「同儕社會支持度」及「採取安全性行為之行為意向」的得分，均顯著優於對照組學生，唯「採取安全性行為之自我效能」並未達到顯著差異，驗證此教學成果是有成效的。
