促进学生有效学习的重要途径是课堂教学。课堂教学是双方面的,既有求知的学生,也有传道授业解惑的教师,在课堂教学中教师是引导学生有效学习过程中最关键的人物。在化学课堂上我们发现很多教师积极的教学行为直接影响着学生的学习效率。一、教师的行为必须能激发学生学习的兴奋点尽管进入了高中,但学生对事物的注意力仍然在12min左右。化学教师选择的教学素材必须创设高潮迭起的教学环境,使学生的认知过程始终处于兴奋层面,那么师生间的教与学一定会产生情感上的共鸣。比如,在讲解化学平衡移动时,以氯气溶于水发生反应为例,可 An important way to promote effective learning is classroom teaching. Classroom teaching is two-sided. There are both knowledge-seeking students and teachers who preach puzzles. Teachers are the most important characters in guiding students to learn effectively in class. In the chemistry class, we find that many teachers’ positive teaching behaviors directly affect the learning efficiency of students. First, the teacher’s behavior must be able to inspire students to learn the excitement Despite entering the high school, but the students attention to things is still about 12min. Chemistry teachers choose the teaching material must create a climax of the teaching environment, so that students always have the cognitive process of excitement, then teachers and students of teaching and learning will certainly have emotional resonance. For example, in explaining the chemical equilibrium shift to chlorine dissolved in water reaction occurs, for example
