The KIS Approach to English Grammar and Composition II is for secular settings. It comes as a result of 35 years of teaching English and hearing legitimate complaints of confusion, consternation, and contempt. So my advise is this: Keep It Simple!
Key--This approach uses the verb as the key to understanding sentence structure built with parts of apeech.
Individual--This approach is a text-workbook comprised of packets with 15 pages or less.
Satisfying--Presenting only necessary knowledge for developing the skill of clear writing, this approach provides a sense of accomplishment without the feeling of being overwhelmed.
