To help the students use more effective words, this teacher should instruct the students to use the thesaurus and use more vocabulary words.
Step-by-step explanation:
A good vocabulary can impress everyone around you. Oftentimes, we see people using non standard English in their day to day lives which may be frowning. Non standard english can be defined as a from of english which uses incorrect grammar or too easy vocabulary.
For example: This is very bad. This phrase seems unpleasant. We can say "this is disgusting" which is much better to hear than the first phrase. Hence the enhancement of vocabulary works like a jewelry to a sentence. Here, the teacher should work on to improve their vocabulary to make their sentences more perfect.
