实验教学是在一定的实验设施条件下,使用一定的实验仪器设备、实验试剂和一些辅助的实验用品,按照一定的操作规范进行的实践教学活动。实验教学过程包括书写实验教案、实验用品准备、预实验、实验讲解与辅导、实验总结、实验报告的批改、实验成绩的评定。其中预实验起着落实实验准备情况、探索影响实验成败的条件、发现可能存在的问题、保证正确的实验效果和学生实验顺利进行等重要的作用。一、落实实验设备和实验器材的准备情况实验教学的准备首先要求教师要认真研究每次实验的教学目的和要求,确定在教学实践中具体可行的方案;钻研与实验有关的原理,启发引导学生理论联系实际;根
Experimental teaching is a practice teaching activity that uses certain experimental equipment, experimental reagents, and some auxiliary laboratory supplies in accordance with a certain operating standard under certain experimental facilities. The experimental teaching process includes the writing of experimental lesson plans, preparation of experimental supplies, pre-experiments, experimental explanations and coaching, experimental summaries, review of experimental reports, and assessment of experimental results. Among them, pre-experimentation plays an important role in the implementation of experimental preparations, exploring the conditions that affect the success or failure of the experiment, discovering possible problems, ensuring correct experimental results, and successfully performing student experiments. First, the implementation of experimental equipment and experimental equipment to prepare for the preparation of experimental teaching First of all teachers are required to carefully study the teaching objectives and requirements of each experiment, to determine the specific and feasible programs in teaching practice; delve into the principles associated with the experiment, inspired to guide students Theory links reality;
