根据科学大纲的精神,现在的科学课强调从问题入手,重在提出问题和解决问题,以提高解决问题能力为核心。而过去的自然课是以人自然为认识对象,所以从观察入手,重在认识自然界,以求得解释,提高学生认识能力为核心。所以我们在教自然课时,把前人对自然的客观规律、客观事实告诉学生,让学生能够认识、理解大自然 According to the spirit of the Syllabus, the present science class emphasizes starting with the problem, focusing on asking and solving the problem, and improving the ability to solve the problem as the core. However, the past natural course was based on human nature as the object of understanding. Therefore, starting from observation, we should focus on understanding nature and seeking to explain and improve students’ ability to recognize as the core.
