根据学生的有效学习的需要,优化教学目标、灵活处理教材,把静止的教材盘活起来,使课堂教学更有效,进而提升学生的学习能力。一、关于目标即使同一个班级,学生的智力水平、数学基础也参差不齐。这就要求教师以优生或学困生的学习情况为依据,应综合考虑知识的难易度以及施教对象的普遍接受能力,提出不同层次的教学目标。以“一元二次方程根与系数的关系”为例:1.低层次目标———掌握一元二次方程根与系数的关系(即
According to the needs of students ’effective learning, the teaching objectives are optimized, the teaching materials are flexibly handled, the stationary teaching materials are revitalized, the classroom teaching is more effective, and the students’ learning ability is enhanced. First, on the goal Even if the same class, the level of intelligence of students, mathematical basis is also uneven. This requires teachers to learn based on the situation of students or students who are poor students, based on the comprehensive consideration of the difficulty of knowledge and the general acceptance of teaching objects, put forward different levels of teaching objectives. Take the example of “the relationship between the root of the quadratic equation and the coefficient ”: 1. Low-level goal --- master the relationship between the root of a quadratic equation and the coefficient
