预设性的化学实验教学使我们在教学中有据可依、有章可循,但传统的化学实验课堂教学过分强调预设,使得化学实验教学不可避免地走向模式化,缺乏对智慧的挑战和好奇心的刺激,缺乏生机与活力。新课程下的生成性的课堂教学精彩纷呈,极富生命气息。因此,在精心的预设下求生成,重视实验课堂的丰富性和复杂性,充分发挥师生的互动性、积极性和创造性,使实验教学课堂始终处于动态生成的过程中,力求使实验教学的预设性目标和生成性目标都能落实,并且相互促进、相互融合,已成为新课程改革中化学实验教学改革的核心内容。
The preconceived chemical experiment teaching makes us have basis and rules to follow in the teaching, but the traditional chemical experiment teaching overemphasizes the presupposition, which makes the chemical experiment teaching inevitably go to the pattern and lacks the challenge to wisdom And curiosity, lack of vigor and vitality. Generative classroom teaching under the new curriculum is colorful and life-like. Therefore, under the meticulous preconditions, students should pay attention to the richness and complexity of experimental classes, give full play to the interaction, enthusiasm and creativity of teachers and students, so that the experimental teaching class is always in the process of dynamic generation, and strive to make experimental teaching The preconceived goal and the generative goal can all be implemented, and mutual promotion and integration have become the core contents of the reform of chemistry experiment teaching in the new curriculum reform.
