科学课较之自然常识课的最大区别就是教学目标变革,引起学习内容、活动组织、课堂形态、教学评价等一系列的革新,最终落实到课堂上,表现为教学的主体性和开放性。这给学生的科学学习提供了自主和选择的空间,给教师的教学提供了开放和创新的空间。教师引导学生利用多种教学资源进行自主探究,积累科学事实与现象,丰富探究经历。因此科学课的开放性给教师带来了巨大的挑战,具体主要表现在教师对科学课堂的组织和调控上。
The biggest difference between the science class and the common sense class is the change of the teaching goal, which arouses a series of innovations such as learning content, activity organization, classroom form and teaching evaluation. Finally, it is implemented into the classroom, showing the subjectivity and openness of teaching. This provides students with the space for autonomous learning and choice of science, providing teachers with open and innovative teaching space. Teachers guide students to use a variety of teaching resources for independent exploration, accumulation of scientific facts and phenomena, to enrich the exploration experience. Therefore, the openness of science class has brought great challenges to teachers, especially in the organization and regulation of teachers in science classrooms.
