在传统化学课堂教学中,教师更多是通过自己的讲授而将化学知识告知学生,学生在听的过程做笔记、记忆,教师再以练习来强化对学生的问题能力培养.这种模式以学科知识为本位,目的是让学生在考试中获得一定的分数,而对学生的问题能力、实践能力培养作用较小.新课改下的化学则以学生的实践能力为出发点,注重突出学生的主体性,让学生在教师的引导下积极参与到课堂学习过程中,通过教师问题的引导,在合作探究中分析并解决问题,进而获得知识的构建,培养其实践能力.在初中化学课堂教学中应用问题教学法,以情境创设来提出问题,以问题引导合作探究,这样才能更好的让学生参与
In traditional chemistry classroom teaching, teachers more often inform their students about their knowledge of chemistry through their own lectures. Students take notes and memorize the process of listening. Teachers then practice to strengthen their problem-proficiency abilities. This model is based on subjects. Knowledge-based, the purpose is to allow students to obtain a certain score in the exam, but little effect on the student’s problem-ability, practical ability training. New curriculum reform of chemistry is based on students’ practical ability as a starting point, pay attention to highlight the main body of students Sex allows students to actively participate in the classroom learning process under the guidance of teachers, analyze and solve problems in collaborative inquiry through the guidance of teacher problems, and then gain knowledge construction and develop their practical abilities. This is applied in junior middle school chemistry class teaching. Problem-based teaching methods: raise questions by setting up situational situations, and guide collaborative explorations with problems so that students can better participate
