观察是一种有目的、有计划、持久的思维知觉,高中化学演示实验需要重点观察实验仪器、实验装置、实验现象,观察教师的操作过程。实验教学能够培养学生的观察能力、思维能力、分析解决问题的能力,从实验演示,培养学生的观察能力;实验操作,培养学生的实践能力;实验探究,培养学生的创新能力等方面探讨了在实验中提升学生的综合能力问题。
Observation is a purposeful, planned, and lasting thinking perception. High school chemistry demonstration experiments need to observe experimental instruments, experimental devices and experimental phenomena, and observe the operation of teachers. Experimental teaching can train students ’observation ability, thinking ability and analyze the ability to solve problems, from the experimental demonstration, training students’ observation ability; experimental operation, cultivating students ’practical ability; experimental exploration, cultivating students’ innovative ability and so on Experiment to enhance the overall ability of students.
