目前高中化学导学案存在设计适切性不强、导学案运用流于形式、导学案沦为“习题集”等问题。教师设计导学案时,应遵循导学诱思原则、梯度性原则、量力性原则、方法性原则、系统性原则,在教学中通过以案导学,引导学生充分预习;以案论学,结合反馈信息组织讨论;以案点学,精讲点拨,启发学生思维。将教师的“引导”与学生的“学习”结合起来,实现“导学合一”。
At present, there are some problems in high school chemistry study case, such as poor design intelligibility, the use of case guides in the form of formalism, Teachers should guide the guiding principle, gradient principle, the principle of compulsion, the principle of principle, the principle of systematization, guide the students to fully preview in the teaching; Combined with feedback information to organize discussions; case study, talkative and refined, inspire students thinking. The teacher’s “guide ” and the student “learning ” combined to achieve “guide to learn together ”.
