学生是否提高化学能力,关键在于化学课堂,而化学课堂是否做到了真正的优化,取决于教学设计的优劣,即看教师的教学目标、教学方法和手段,教学过程中教与学的双边活动的构思和安排是否达到最优化。下面就化学课堂教学实践和体会,本人认为应注重以下三个原则:一、注重教学目标的落实教学目标是教学双方积极活动的准绳,是衡量教学质量的尺度。明确具体的教学目标对教师的教的方式以及学生学的方式起着决定和制约作用。因此,制订教学目标时要考虑以下问题:(1)使学生学到哪些知识?学到什么程度?(2)巩固哪些 Whether the students improve chemistry ability depends on the chemistry class, but whether the chemistry class truly optimizes or not depends on the advantages and disadvantages of the teaching design, namely, the teaching goal, teaching methods and means, the bilateral activities of teaching and learning in the teaching process Whether the concept and arrangement are optimized. The following chemistry classroom teaching practice and experience, I think we should focus on the following three principles: First, pay attention to the implementation of the teaching objectives Teaching objectives are the yardstick for both teaching and learning activities, is a measure of the quality of teaching. Clearly specific teaching objectives on the teacher’s teaching methods and student learning plays a decisive and restrictive role. Therefore, the following questions need to be considered when formulating teaching objectives: (1) What knowledge should be learned from the students? To what extent? (2) What should be consolidated
