数学基本活动经验是《数学课程标准》(20011版)提出的“四基”之一。作为引导学生积累数学基本活动经验重要载体的“探索与实践”内容,教师教学时仍存在理解偏颇、认识不到位、随意性大等问题。因此,教师要根据“探索与实践”内容的特点,通过省时、交流会等有效教学的策略,引导学生积累数学基本活动经验。
The basic experience of mathematics is one of the “four bases” proposed by the “Mathematical Curriculum Standard” (20011 edition). As a part of “exploration and practice” that guides students to accumulate experience as an important foundation for mathematics activities, there are still problems such as misunderstanding, ignorance and arbitrariness in teacher teaching. Therefore, teachers should guide students to accumulate the experience of basic activities of mathematics through effective teaching strategies such as saving time and exchanging information according to the characteristics of “exploring and practicing” contents.
