I had always thought that writing should be learned, not in isolation as a separate subject, but in the course of using it to do actual writing about topics that interest the child. TWSS is designed to be incorporated with other school subjects, particularly history, science and literature. Our family used it mainly with our world history studies. Each child was assigned to a particular person or event from a history unit and wrote about it at his or her own level. The younger children practiced their writing skills by making "keyword" outlines of paragraphs I selected for them from their history texts and then orally narrated them to myself or an older sibling. My older children wrote longer summaries from their outlines and learned the various writing "dress-ups" to add to their compositions to improve the style of their writing.
The goal for each child using WSS is to gradually achieve writing independence, choosing the source texts for their own writing and then composing a well-written essay, report, critique or narrative.

Skills taught through Teaching Writing: Structure and Style include: note taking and outlines, summarizing from notes, summarizing a reference, library research reports, essay writing, summarizing narrative stories, writing from pictures, creative writing, and critiques. 

The format of the program is a 2 day seminar presented to the teacher on 6 DVD's. Our recommendation is to not watch the entire seminar before starting, just watch a disc at a time and begin teaching those concepts before moving on to the next. The program includes a seminar notebook, sample lesson plans and three bonus DVD's presenting the first lesson to students at various grade levels. Use this program to learn to teach writing from second grade through High School.

This is a one-time investment in a non-consumable program that you will be able to use with every child, every year!
