反馈串是指在课堂教学实践中,教师通过设置一系列的检测方式,来对自己在课堂所设置的问题情境、教学活动、教学内容做效果反馈,也是学生学习效果的反馈.在形式多种多样的效果反馈中,要根据学生的课堂活动方式,与高中化学的教学目标相结合,充分考虑学生学习后的目标达成,依次建立的即时评价、连续评价、学习量表、阶段评价等反馈串,才能真正的量化学生的学习,不但是对学习效果的检测,更是效果反馈中的再提高.一、即时评价,树立坚定信心在课堂教学中,教师的口头评价是最直接、最有效的评价方式.为了全面了解学生对化学的学习情况,会随时在课堂上要进行提问和练习,学生的反馈直接揭示了其对知识的理解程 The feedback string means that in the classroom teaching practice, teachers set a series of testing methods to make feedback on the problem situations, teaching activities and teaching contents that they set in the classroom, as well as feedback on the students’ learning effects. According to the students’ classroom activities and the teaching goals of high school chemistry, various feedbacks should be given full consideration of the goals reached by the students after learning, such as instant evaluation, continuous evaluation, learning scale and stage evaluation , In order to truly quantify the learning of students, not only the detection of learning effects, but also the feedback of the effect of the re-increase.Indirect evaluation, establish a firm confidence in the classroom teaching, the teacher’s oral evaluation is the most direct and effective Evaluation methods.In order to fully understand the students learning chemistry, will be in the classroom at any time to ask questions and practice, student feedback directly reveals the knowledge of the process of understanding
