对于学生来说,渴求知识的欲望往往伴随学习的兴趣而生。开发学生学习动力源,激发学生的学习积极性,有助于培养学生自觉学习、主动学习的意识,更利于引导学生端正学习态度,掌握学习策略,进行探究性学习。如何开发学生的学习动力源?我在化学教学中积极进行“四个转变”的实践,使学生对化学的学习实现了由情动、心动到行动的良性循环,从而促进了教学质量的提高。一、改进表现形式,变“教师独唱”为“师生合唱”我注意选用“发现学习”模式、“集体讨论”模式等教学模式组织课堂教学。最大限度地让学生参与教学活动,并 For students, desires for knowledge are often born with the interest of learning. To develop students ’motivation to learn and motivate their enthusiasm for learning will help to cultivate students’ consciousness of conscious and active learning, and will be more conducive to guiding students to correct learning attitude, master learning strategies and conducting exploratory learning. How to develop students’ motivation to learn? In my teaching of chemistry, I actively carry out the practice of “four transformations” so as to enable students to realize a virtuous cycle of emotion learning and heartbeat to action in chemistry learning so as to promote the teaching quality improve. First, to improve the performance of forms, change “teacher solo ” “teacher and student choir ” I pay attention to choose “discovery learning ” mode, “group discussion ” mode and other teaching modes to organize classroom teaching. Maximize student engagement in teaching activities
