课堂教学中,教师为了调动学生的学习积极性,激发学生的探索热情,创设了学生喜闻乐见的学习情境,这也是新课程所倡导的。但是,在教师所创设的情境中,有很多是不切实际的,甚至有的还是在欺骗学生,这与教育教学目的——教育学生追求真、善、美是相违背的。因此,教师应做到“一诺千金”! In classroom teaching, in order to arouse students ’enthusiasm for learning, inspire students’ enthusiasm for exploration and create a learning situation that students like to hear, this is also what the new curriculum advocates. However, in the situation created by the teachers, many of them are unrealistic and some even deceive the students. This is against the purpose of education and teaching - to pursue the truth, goodness and beauty of the students. Therefore, the teacher should do “as good as gold ”!
