Activity reflection
Common sense of household appliances is a new course, that is, there are no teaching materials and reference materials, so the teaching difficulty can be imagined. In view of the situation that vocational school students are tired of boring explanations and like flexible and diverse practice plus practical teaching, a large number of media courseware and video materials have been accumulated in recent years, which have played an important role in teaching.
Practice teaching fully mobilized students' learning enthusiasm. They are not afraid of dirt and oil. They squatted underground and began to work, which was completely different from sitting in the classroom. Through practical training, students have a deep and extensive knowledge and are particularly easy to remember.
A few days ago, I made a phased assessment of the common sense of household appliances. I adopted a three-step assessment method:
The first step of the assessment is to fill in the blanks, not close the papers, so that everyone still has to memorize the basic knowledge by heart, accounting for 30 points.
The second step is to investigate the disassembly and assembly of the training, including the disassembly and assembly of the air conditioner and refrigerator. This assessment includes the correct use of electrical appliances, the standardized placement of disassembled items, and finally completely restored to the state when disassembled. Thirty-five points.
The third step is the common sense of using household refrigerators and air conditioners. By drawing lots, which one will be tested, this is an assessment method described while operating. Thirty-five points. It's a hundred points.
Through such teaching and assessment, I think it can not only cultivate students' good study habits of using their hands and brains, but also increase students' initiative in learning and make the teaching progress more complete.
