“解决问题”是数学新课程标准四大目标之一。在实际教学中,“解决问题”是小学数学教学的重点和难点,它可以有效地训练学生的创新思维和表达能力。《义务教育数学新课程标准》要求在数学课堂教学中充分发挥学生的主体性和教师的主导性作用,让学生在合作学习、主动探索中求知。在“解决问题”教学中实施合作交流、主动探索式教学,具体有什么策略呢? “Solving Problems ” is one of the four major goals of the new mathematics curriculum standard. In practical teaching, “solving problems” is the key and difficult point of elementary mathematics teaching, which can effectively train students’ innovative thinking and expressing ability. The new curriculum standard of compulsory education mathematics requires students to give full play to their subjectivity and teachers’ dominant role in mathematics classroom teaching so that students can learn through cooperative learning and active exploration. In the “problem-solving” teaching in the implementation of cooperation and exchange, take the initiative to explore teaching, what are the specific strategies?
