Teaching plan writing skills

1, preparation before class

Students' preparation for learning; Teachers' teaching preparation; Design and layout of teaching environment; Design and preparation of teaching tools, such as tape recorders, teaching tapes, teaching wall charts, cards, objects (or models), small blackboards, lettering exercises, colored chalk, slides, etc.

2. Teaching procedures

Teaching process is the main part of teaching plan. Write the teaching links clearly. The teaching link, that is, what is the teaching task, should be written clearly and be aware of it. At present, some teachers adopt "three stages and six links" teaching mode, namely: preview stage (free communication, review and inspection), lecture practice stage (course introduction, layered practice) and development stage (consolidation and development, assignment).

Write down the knowledge points and the time spent. Write the knowledge points well, so that teachers can see at a glance when using the lesson plan. Writing down the time used can help teachers master the teaching speed calmly, arrange the time needed for each teaching link reasonably and make full use of classroom time.
