提高教学效果是作为一名教师亘古不变的主题。也是每位教师的必然追求。学生的注意力是有限的,让一个学生45分钟将所有的注意力都集中在课堂教学中几乎是不可能的。想想看即使你在看一部非常感人的电影,也有可能被周围发出的声音吸引,何况在一间教室里坐着几十个形形色色不同的个体——学生呢?学生在课间玩得很兴奋,如何在上课伊始就抓住学生的眼球、让学生的思路顺着老师引导的路径走呢?下面就结合本人多年的教学,谈谈对这方面的认识。1.创设好的问题情境,让每个学生都有所思。什么样的事物才能触动孩子,使他们大脑细胞变得活跃起来呢?1.1所提问题紧绕学生亲身经历的事情。如在讲述汽化时问题:夏天,人们常用扇子或电扇降温;冬天,寒风吹来觉的特别冷,风能降低温度吗?学生实验验证:对着温度计的玻璃泡扇扇子,观察温度计示数的变化。给温度计穿上棉袄,观察温度计示数的变化。
Improving teaching effectiveness is a permanent theme as a teacher. It is also the inevitable pursuit of each teacher. Students’ attention is limited and it is almost impossible for a student to concentrate all their attention in class teaching for 45 minutes. Think about it Even though you’re watching a very moving movie, it’s possible to be attracted by the sounds around you, not to mention sitting in dozens of different classrooms - students - students have fun in class Excitement, how to catch the eyes of students at the beginning of the class so that students follow the path of teacher guidance to go? The following combination of my years of teaching, to talk about this understanding. 1. Create a good problem situation, so that every student thoughtfully. What kind of things can touch the child, make their brain cells become active? 1.1 questions raised around the students first-hand experience of things. As in the description of the problem of vaporization: In summer, people often cool with fans or fans; In winter, the cold winds feel particularly cold, the wind can reduce the temperature? Student experimental verification: facing the thermometer glass fan fan, observe the thermometer Variety. Put a thermometer on the jacket, observe changes in the thermometer.
