MASTERY LEARNING OF WRITING SKILLS

Mastery Learning suited teaching of English as a second language. At every PNG school, I had taken all grades from Grades 8-12 in mastering the basics of written English.

I had developed a work book of integrating sentences with 240 exercises to be mastered and revised over a six month period. Capable students mastered the basics in a month or two. 
This is a massive change from the approach of many PNG teachers. They explain once in English. Teachers copy the summary down on the black board. Then they move on with many students none the wiser.
One foolish teacher criticized Mastery Learning to me. He said that he only ever explains once. If students do not understand, it is because they were not listening. That is an insult to him. They deserve to fail. Stupid man.
I drill the same basics 50 times and even then many students do not remember. But more of my students pass the final exam with high marks.
I have a workbook that contains 240 groups of sentences to be combined, one at a time as below. It can begin with primary school children and end with grade 12 students. 
Repeated words are removed and sentences combined with appropriate connector words. Students are being groomed into polished writing. 
High school students use listing in assignments. All students in all grades start at the start of these mastery patterns. They master every pattern from grade to grade.
