I'm a high school English teacher, and what I find is that a lot of kids come into high school without much understanding of grammar and punctuation. A lot of kids tend to have fantastic ideas, but they have a really hard time organizing their ideas and then communicating them in grammatically correct sentences. As far as I can tell, most schools seem to have abandoned traditional grammar instruction, and the grammar/writing instruction that kids do get is very haphazard. Schools and educators tend to prioritize ideas/thoughts/creativity over grammar/punctuation/clarity. I personally think that we need to encourage kids to think deeply and creatively, but we ALSO need to help them learn how to express those ideas as clearly and powerfully as possible.
So here's what I do with my own kids:
- Encourage lots of reading (there's such a clear and obvious correlation between reading and writing)
- Some explicit grammar instruction on weekends (parts of speech, capitalization and punctuation rules, active versus passive, dangling and misplaced modifiers, subject-verb agreement etc.)
- Occasionally (maybe once a month), I get my kids to write paragraphs. I expect my DS, now 11, to write analytical paragraphs, where he analyzes a character or theme in a book he has been reading. I work with him on planning his paragraphs with a topic sentence + supporting evidence and analysis.
I ask my DD, who is 7, to write on any topic of her choice, and I focus more on helping her hone her control over language. With both kids, I'll make them do at least two drafts of their paragraphs, so that they begin to understand the importance of revising and editing their work. I would love to do more writing with them, but between their schoolwork and my work, we don't have as much time as I would like.
And here's a blogpost I wrote some time ago on grammar instruction.
