3. Understanding involves example, explanation, and practice
At different times structure has been taught in very different ways.
Something, partly because of the language itself, and partly perhaps because of mistake ideas introduced in the student’s earlier learning explicit explanation may be much more important. In fact, all questions follow the same pattern and the explicit statement of a rule may help students to see this.
To make a questions invert the order of the subject and firs auxiliary; if there is no auxiliary introduce (do) as a “dummy” auxiliary, and follow the basic rule.
Understanding is a cycle which involves each of explicit explanation. It is not sufficient for students to understand intellectually; what students “understand” should directly influence their language performance. This is best achieved if teachers constantly bear in mind the important link between explanation, example, and practice.
