在小学科学课教学活动中,教师需要结合教材内容为学生开展对比实验,帮助学生发现事物变化的自然规律,使学生掌握更多的科学知识,并且还需要培养学生的实验操作能力及观察能力。教师如果优化科学对比实验教学,需要从用心准备实验所需的仪器材料、由指导到独立、逐渐提升学生实验技能、及时调整对比实验方案等方面考虑,积极促进学生实验的主动性,从而促进对比实验能够推动学生科学研究的有效发展。
In the teaching activities of primary science, teachers need to carry out comparative experiments for students according to the content of teaching materials, help students discover the natural laws of things change, enable students to acquire more scientific knowledge, and also need to cultivate students’ experimental skills and observation skills. If teachers optimize scientific comparative experimental teaching, they need to actively prepare students for experimental experiments by actively preparing the necessary instrumental materials for experiments, guiding them to independence, gradually improving students’ experimental skills, and adjusting experimental programs in time so as to promote comparison Experiments can promote the effective development of students’ scientific research.
