在高中化学的课堂上,通过创建一定的情景,引导学生在实验或对事物的思考中发现问题,针对提出的问题进行分析探讨得出解决方案,并及时进行反馈评价.通过这样的问题解决教学法,学生亲自来体验对知识的产生和获得的经历,培养学生的问题意识,建立科学高效的解题方法,并在不断的总结反思中,提高学生的能力,是实施问题解决教学的关键所在.一、创设情景,激发问题兴趣问题解决始于良好的问题情景.老师应该结合学生的认知、情感和生活经验,将授课内容隐置在问题情景中,使学生在对有趣、生动情景素材中主动提出问题,与老师一起结合新旧知识共同分析问题、解决问题.因此建立良好的问题情景是关
In the high school chemistry class, through the creation of certain scenarios, guide students in the experiment or in the thinking of things to find problems, analyze and discuss the problems raised to come up with solutions, and timely feedback evaluation. Through such problems to solve teaching Law, students personally experience the generation and acquisition of knowledge, cultivate students’ problem awareness, establish a scientific and efficient method of solving problems, and constantly improve the students’ abilities in summarizing and reflecting, which is the key to implement problem solving teaching. 1. Creating a scenario to stimulate problem interest The problem resolution begins with a good problem scenario. The teacher should combine the students’ cognition, emotion and life experience to hide the content of the lecture in the problem scenario so that the student can have interesting and vivid scene materials. In the initiative to ask questions, together with the teacher to combine the old and new knowledge to analyze problems and solve problems. Therefore establishing a good problem scenario is
