高中化学探究教学要遵循适度、适时、适量的原则,精心选择、巧妙设置、及时深化,让探究学习更高效.一、探究教学的“三适”原则在教学实践中,探究教学会受到各种主客观因素的影响.要想使探究教学发挥最佳效果,需遵循几个原则.1.适度教师要控制好探究学习内容的难易程度.过易,学生的探究难免流于肤浅;过难,学生不易开展探究活动.如,NH3是否溶于水就不需要做过多的探究,而氨气溶于水形成的喷泉实验
High school chemistry inquiry teaching should follow the principle of appropriate, timely and appropriate, careful selection, ingenious setting, timely deepening, make inquiry learning more efficient .In order to explore the principle of “three fitness” of teaching, in teaching practice, inquiry teaching will be affected Various subjective and objective factors.If you want to make the best of the teaching of inquiry, you need to follow several principles.1.Some teachers should control the difficulty of exploring the learning content.Over course, the exploration of students will inevitably be superficial; Too difficult for students to explore activities, such as, NH3 is not dissolved in water do not need to do too much exploration, and ammonia dissolved in water formed fountain experiment
