教学情境是教师和学生展开对话、进行思想和心灵交换的场所,是激活学生已有经验、产生认知冲突和探究欲望的生长点,更是教材走向心理、思维不断升华的载体,因此教师在课堂教学中,首要任务之一应是创设教学情境,激发学生的学习兴趣,使学生乐学、爱学从而引起学生情感的共鸣,从而诱导学生投入到丰富多彩、充满活力的数学学习活动中。《义务教育数学课程标准》也明确要求在课堂上把“学”的权力还给学生,把“想”的时间交给学生,把“做”的机会让给学生。那么,如何从学生的实际出发,创设行之有效的数学情境呢?
The teaching situation is a place where teachers and students can start dialogues and exchange ideas and minds. It is a growth point for activating students’ experience, generating cognitive conflicts and exploring desires. It is also a carrier for teaching materials to move toward psychology and constant sublimation of thinking. Therefore, teachers One of the most important tasks in classroom teaching should be to create a teaching situation and stimulate students ’interest in learning so that students can learn music and learn arousal in order to arouse students’ emotional resonance so as to induce students to devote themselves to colorful and energetic math learning activities. The Compulsory Education Math Curriculum Standard also explicitly requires that students be given the power of learning in class and give their students the chance to do their work. So, how to create effective mathematical situations from the students’ reality?
