“综合与实践”是一类以问题为载体、以学生自主参与为主的学习活动。在学习活动中,学生将综合运用“数与代数”、“图形与几何”、“统计与概率”等知识和方法解决问题。它有别于学习具体知识的探索活动,更有别于课堂上教师的直接讲授。它是教师通过问题引领、学生全程参与、实践过程相对完整的学习活动。“综合与实践”的教学活动应当保证每学期至少一次,可以在课堂上完成,也可以课内外结合。从《全日制义务教育数学课程标准 “Synthesis and Practice ” is a type of learning activities that takes question as the carrier and students’ independent participation as the mainstay. In the learning activities, the students will comprehensively use the knowledge and methods such as “Number and Algebra”, “Graphics and Geometry”, “Statistics and Probability” to solve the problem. It is different from the exploration of learning specific knowledge, more different from the direct teaching of teachers in the classroom. It is a teacher through questions, students participate in the whole process of learning is relatively complete learning activities. “Comprehensive and practical ” teaching activities should be guaranteed at least once a semester, can be completed in the classroom, can also be combined inside and outside the class.
