本文根据“遗传信息的表达——RNA和蛋白质的合成”一节中概念较多的特点,应用5E教学模式,引导学生开展探究性学习活动,促进学生新旧概念的认知冲突,帮助学生自主建构、理解并应用新概念,提高核心概念教学的有效性。
This article uses the 5E teaching model to guide students to carry out exploratory learning activities based on the concept of “expression of genetic information—the synthesis of RNA and proteins” in the section to promote cognitive conflict between students’ old and new concepts. Independently construct, understand and apply new concepts to improve the effectiveness of core concepts teaching.
