所谓即时反馈,就是指课堂教学中教师针对学生的学习情况而及时采取的回应与引导,是教师课堂教学中的一项基本功。在“学为中心”的初中化学课堂教学中,引导初中生进行高效化的化学学习是十分重要的。而在构建高效初中化学课堂的过程中,教师的即时反馈是十分重要的教学手段,因为有效的即时反馈能够对学生的化学学习情况进行及时捕捉,并在此基础上引导他们进行深入的化学思考与化学探究。 The so-called instant feedback, refers to the classroom teaching teachers in response to student learning and timely response and guidance, is a basic teaching of teachers. In junior high school chemistry classroom teaching with “learning as center ”, it is very important to guide junior high school students to carry out efficient chemistry study. In the process of constructing a high-efficiency junior high school chemistry class, teachers ’immediate feedback is a very important teaching method because effective immediate feedback can capture the students’ chemistry learning in time and guide them to carry out in-depth chemical thinking And chemical exploration.
