三、突出技能,强调创新的实验题更加注重实验能力的检测,力图避免“背实验”和在黑板上做实验的倾向,出现了许多好的设计实验题。特点:一是跳出教材中学生实验和演示实验的束缚,不再是从学生实验和演示实验中挖掘、编制考题;二是要求学生自己独立设计实验方案,选择实验器材,制定实验步骤;三是试题具有开放性,设计方案的不惟一性给学生提供了很大的灵活运用知识、发挥能 Third, highlighting skills, emphasizing that innovative experimental problems pay more attention to the detection of experimental abilities, trying to avoid “back experiment ” and the tendency to experiment on the blackboard, there have been many good design experiments. Features: The first is to jump out of the constraints of the student’s experiment and demonstration experiment in the teaching materials. It is no longer to dig and prepare the questions from student experiments and demonstration experiments. The second is to require the students to independently design the experimental program, select the experimental equipment, and make experimental steps; It is open, and the uniqueness of the design scheme provides students with a great deal of flexibility in the use of knowledge and performance.
