We must now go back to the Sentence Completion Exercise, which has also grown out of reproduction, and plan a course of increasing difficulty, using this exercise. At first, the part of the sentence to be added by the children should be Obj., Adv. and Adj.; then adverbial phrases. These will be the easiest to begin on. In the first few lessons, at least, it will be necessary to run through the exercise orally before writing begins. The purpose of this is to give as much help as possible to the class in order to have the written work done correctly, and not allow tot much freedom of choice. After these simple beginnings have been well practiced, longer completions may be demanded; but, again, suggestions should first be discussed orally, especially with slow classes. With a very good class, the pupils could be asked to explain why some suggestions were rejected; they should be able to see where incorrect structure, absurd idea, unintelligibility, untrue fact, etc. account for rejection. This gives a sharp stimulus to the quickest pupils, and will urge to make up better sentences.
