我认为小学科技活动课不仅仅是读读课本,了解一些简单的科学常识,或做做手工,更重要的是通过科技活动激发学生的求知热情、探索科学道理,培养他们的科学精神和实践能力。因此,教师要在备课上下工夫,结合课本内容搞课题设计,课内与课外相结合,实践与认识相结合,个人与集体相结合才能获得实效。教师要鼓励学生到生活和大自然中去观察,去实践,去认识,去创新。给学生充分的时间、空间,让学生有选择、有补充、有创新,让科技活动成为以学生为主体的自主活动。 活动课题设计要根据学生的年龄特点和认识能力, I think primary science and technology activity class is not just reading textbooks, understand some simple scientific knowledge, or do manual, more important is to stimulate students' knowledge and enthusiasm through science and technology activities, to explore the scientific truth, to develop their scientific spirit and practical ability . Therefore, teachers should make efforts to prepare lessons, combine the contents of the textbook with the topic design, the combination of class and extracurricular activities, the combination of practice and cognition, and the combination of individual and collective in order to obtain practical results. Teachers should encourage students to observe life and nature, to practice, to recognize and to innovate. Give students full time and space, so that students have the choice, there is a supplement, innovation, science and technology activities as a student-centered initiative. Activities subject design according to the characteristics of the students' age and cognitive ability,
