“好的开始是成功的一半!”对于上课而言,导入作为第一锤很重要,一定要敲在学生心灵上,在敲打下,学生思维的火花四溅。笔者认为,导入要能激发学生的学习兴趣,又不能失去物理味。本文结合笔者的教学案例,介绍一种高中物理有效的课堂导入方法——悬念导入法。“好奇之心,人皆有之。”好奇心是驱动认知发展的积极正情绪。理论研究和实践也证实,高中学生对奇特的事物和现象会比较好奇,对有悬念的事物有一种欲一探究竟的心理需要。悬念导入法就是基于学生的这一特点而提出来的导入方法,也符合物理学观察生活表象然后质疑、猜想和探究的学科特点。一、一般流程悬念导入法,主要有三个部分组成:问题情境;设置悬念;发现问题。操作的一般流程如图1所示,借助于新旧知识联系、物理学史、演示实验、生活 “Good start is half the battle! ” For class, it is important to introduce as the first hammer, be sure to knock on the student’s heart, under the beat, the students’ thinking sparks. I believe that the introduction should be able to stimulate students interest in learning, but also can not lose the physical taste. This article combines the author’s teaching case, introduces a high school physics effective classroom introduction method - suspense into law. “Curiosity, everyone has it.” Curiosity is a positive sentiment that drives cognitive development. Theoretical research and practice also confirm that high school students are curious about strange things and phenomena and have a psychological need to find out suspenseful things. Suspense into law is based on the characteristics of students and put forward the introduction of methods, but also in line with the physical appearance of life and then questioned, guess and explore the characteristics of the discipline. First, the general process Suspense into the law, there are three main components: the problem context; suspense set; find the problem. The general operation of the process shown in Figure 1, with the help of old and new knowledge links, history of physics, demonstration experiments, life
