现在的科学课程与过去的《自然》教材相比,内容更加贴近学生生活,活动更加强调学生探究,目标更加注重学生对科学概念本质的把握和理解。然而由于学生年龄特征、认知特点及思维发展水平和经验等的局限,他们往往不能正确理解有关概念,常常产生错误,影响科学课程的教学。教师要进行有效的科学教学,必须对学生的错误概念及其影响有一个正确的认识。 Compared with the past “natural” teaching materials, the current science curriculum is closer to student life. Activities emphasize student inquiry, and the goal is to pay more attention to students’ understanding and understanding of the nature of scientific concepts. However, due to the limitation of age, cognition, level of development and experience of students, they often can not correctly understand the concepts and often make mistakes that affect the teaching of science curriculums. To carry out effective science teaching, teachers must have a correct understanding of the mistaken concept of students and their effects.
