小学数学开放性教学是指在开放的课堂教学目标和开放的教学环境下,借用现实的、丰富的教育教学资源,采用开放的教学组织形式、自主活泼的教学方式和积极有效的评价方法而进行的最终使学生在知识、技能、情感、态度等方面得到全面、和谐发展的一种教学。实施开放式教学,是一个系统工程,只有保证目标系统、资源系统、环境系统和评价系统等子系统的充分开放,真正激活,才能撑起小学数学开放式的课堂。 Primary school mathematics open teaching refers to the open classroom teaching objectives and open teaching environment, the use of realistic and rich educational resources, the use of open teaching organization, self-active and lively teaching methods and positive and effective evaluation methods Finally, students can get a comprehensive and harmonious teaching of knowledge, skills, emotions and attitudes. The implementation of open teaching is a systematic project. Only when subsystems such as target system, resource system, environmental system and evaluation system are fully open and truly activated can we hold up an open class in elementary mathematics.
