摘 要 通过对“抛砖引玉”教学模式的探索,在课堂教学中,运用“抛砖引玉”的技巧,引发学生的探究之欲和思维发展。在科学课教学过程中,围绕教学目标精心设计教学语言,通常能起到知识上的承上启下、内容上的点明主题、战术上的激发兴趣等作用。在教学中运用“抛砖引玉”的方式,巧妙的进行导入,引导学生进入学习状态,最大限度地调动学生探求知识的主动性。

Abstract: Through the exploration of the teaching mode of "throwing a brick to attract jade", in the classroom teaching, the skills of "throwing a brick to attract jade" are used to arouse students' desire for exploration and thinking development. In the process of science teaching, the teaching language is carefully designed around the teaching objectives, which can usually play the role of connecting the preceding and the following in knowledge, pointing out the theme in content and stimulating interest in tactics. In teaching, we should use the method of "casting a brick to attract a jade" to guide students into learning state and mobilize their initiative to explore knowledge to the greatest extent.
Keywords: throwing a brick to attract jade; class teaching; elaborate design; thinking development

文艺演出非常讲究开场,写文章也很注意怎样开篇。在教学中,每堂课如何“抛砖”同样也大有学问。对每堂课开场的抛“砖”,也就是导入的开发利用,是每位教师必须谨慎对待的问题。
课堂不同,“砖”的形态也各异。最普通的“砖”可能只是一件简单的实物。如《果实的形成》一课,教师在上课伊始出示又红又大的苹果、翠绿的黄瓜、红红的辣椒等实物,以引起学生的关注。……
