新的《数学课程标准》指出:数学教学应从学生实际出发,创设有助于学生自主学习的问题情境,引导学生通过实践、思考、探索、交流,获得知识,形成技能,发展思维,学会学习,促使学生在教师指导下生动活泼地、主动地、富有个性地学习。因此,精心创设情境是提高数学课堂教学有效性的一项重要策略。然而,新课程下的一些数学课,情境只是为创设而创设,只图表面热闹,而无实际效果,有时甚至成了说话课,夹杂了太多的
The new “Mathematics Curriculum Standard” points out that mathematics teaching should start with students’ actual conditions, create problem situations that help students to learn independently, guide students through practice, thinking, exploring, communicating, acquiring knowledge, developing skills, developing thinking, learning to learn, Promote students to live under the guidance of teachers, active, full of personality learning. Therefore, careful creation of context is an important strategy to improve the effectiveness of classroom teaching in mathematics. However, some math classes under the new curriculum, the situation is only created for the creation, only the surface lively, without the actual effect, and sometimes even become a talking class, mixed with too much
