学生掌握实验技能，远非一日之功，往往要通过较长的时间的反复操作、矫正、强化，才能准确掌握达成目标。为此，我校化学组自1989年始把学生实验技能的检测安排在实验课程的终端，并对学生技能操作的内容及方法进行不断的实践，探究了终结性化学实验技能目标达成度的认定，其 Students’ mastery of experimental skills is far from a day’s work, and it is often through repeated operations, corrections, and reinforcements over a long period of time that the achievement of goals can be accurately grasped. To this end, the chemical group of our school has been arranging the testing of students’ experimental skills at the end of the experimental course since 1989, and has continuously practiced the contents and methods of the students’ skill operations, and explored the determination of the achievement of the final chemical experiment skill target. its
