Why Johnny Can’t Use Good Grammar

Some years back, the principal walked into my room while my student teacher was delivering a lesson. After a few minutes, the principal signaled me to step outside.

“I would never hire Johnny to work at my school,” he said.

Shocked, I asked him why.

“On the board, he has a misplaced comma, and he ended a sentence with a preposition.”

Sounds quite harsh, doesn’t it? That principal certainly had high expectations of his

teachers. Not every educated adult places the same level of importance regarding the proper use of grammar and mechanics as does that principal. However, many do.

Proper grammar is a critically important tool for success in school, work, and life. We are judged, sometimes quite severely, by the words we use and the way we use them in both our speaking and writing. Misused grammar betrays us. The way we talk and write reflects our background, education, and ability to communicate.

The Five Myths of Grammar Instruction

1. Grammar is acquired naturally; it does not need to be taught. Oral language is not always an efficient teacher. In fact, it can be quite a mixed bag. For every proper modeling of the pronoun in the sentence: It is I, students hear at least five models of the incorrect: It is me. Grammar as it is caught must be complemented by a grammar that is taught.

2. Grammar is a meaningless collection of rules—most of which don’t work half the time. This myth may have developed from mindless “drill and kill” grammatical exercises with no application to real writing. Actually, our English grammar is remarkably flexible and consistent.

3. Grammar cannot be learned by students with some learning styles or disabilities.

While it may be true that students learn language differently, at different rates, and vary in proficiency, there has been no research to show that some students cannot learn grammar.

4. English grammar cannot be learned by second language learners. Some teachers think that students who speak other languages get confused between the primary language and English grammars. The research proves otherwise. Intuitively, many of us have significantly increased our own knowledge of English grammar by taking a foreign language.

5. Reading and writing a lot will improve grammar. Reading grammatically rich literature is wonderful, but learning is not passive and does not come by osmosis. Writing poorly may, indeed, reinforce poor grammatical usage.

How we should teach grammar to Johnny…

Don’t waste time teaching Johnny what he already knows. Find out what he does not know and target these areas of grammatical deficits. Use the free diagnostic Grammar Assessment and Mechanics Assessment found on to pinpoint specific skill deficits. Have Johnny practice those weaknesses with specific skill worksheets. You can find these resources at your local bookstore, on the web, or in Teaching Grammar and Mechanics ©2004 Pennington Publishing. Who says teaching grammar in isolation is ineffective? Indeed, it is effective and efficient.

Teach the language of grammar and recognition of the common grammatical structures. Johnny has to know what a prepositional phrase is and how to know one when he sees one. In fact, over 30% of academic writing is composed of this grammatical form. Maybe learning “Conjunction Junction, What’s Your Function” on Sesame Street® was not such a bad idea after all. The “Parts of Speech Rap” in Teaching Grammar and Mechanics serves this need nicely.

Teach grammar in the context of writing. Using the common grammatical structures, have Johnny begin half of his written sentences with different sentence openers. This practice serves two purposes: It teaches recognition and manipulation of grammatical structures and it improves sentence variety. Teaching Grammar and Mechanics has a terrific set of sentence openers, using all of the common grammatical forms found in superior writing.
