教师仅仅做化学知识的传授者已经不能满足时代的要求,要实现知识课堂到思维课堂的转变,教师则在思维课堂教学中充当着情境的创设者、活动的组织者、学生思维发展的协助者和问题探究的指导者等多重角色。“问题”是贯穿思维课堂的一条主线,根据中学生思维发展的特征,教师指导学生在发现问题、提出问题的过程中,应注重问题的层次性和延展性,将课堂的学习与思维推向更宽广的领域。 Teachers can not meet the requirements of the times just by doing the teaching of chemical knowledge, and change the knowledge-based classroom to the thinking classroom. Teachers are the creators of the situation, the organizers of activities, the facilitators of the development of students’ thinking in thinking classroom teaching And the problem of inquiry mentor and other multiple roles. “Problem ” is a main thread running through the thinking class. According to the characteristics of middle school students’ thinking development, teachers should guide students in the process of discovering problems and asking questions. They should pay attention to the level and extensibility of problems, and push learning and thinking in class To a broader area.
