To summarize: if caretaker speech is helpful for language acquisition, it may be the<br />

case that simple codes are useful in much the same way. The teacher, the more<br />

advanced second language performer, <strong>and</strong> the native speaker in casual conversation,<br />

in attempting to communicate with the second language acquirer, may<br />

unconsciously make the "100 or maybe 1000 alterations in his speech" that provide<br />

the acquirer with optimal input for language acquisition.<br />

Re-analysis of Classroom Exercises<br />

In the previous sections, I have attempted to state the following hypothesis: simple<br />

codes such as teacher-talk, interlanguage-talk, <strong>and</strong> foreigner-talk aid second<br />

language acquisition for adults in much the same way that caretaker speech aids<br />

child language acquisition. If this is the case, if our hypothesis is supported by<br />

subsequent research, we can then ask how classroom exercises compare to simple<br />

codes. In this section, I anticipate this discussion with some general comments on<br />

the role of classroom exercises.<br />

There are various possibilities for classroom exercises. First, they can be classified<br />

as to whether their focus is on gaining formal or conscious knowledge of the target<br />

language (Monitor), or whether their goal is on gaining acquired or subconscious<br />

knowledge. The former are grammar exercises, the latter communicative exercises.<br />

Of course, some exercises may do both at once, but we will find it useful to<br />

maintain this distinction for the moment.<br />

Classroom exercises, in considering one grammatical structure of the target<br />

language at a time, may vary as to whether they "hit" the acquirer's i + 1<br />

structure(s). An exercise may undershoot, hitting a structure that has already been<br />

acquired, it may overshoot, hitting far beyond i + 1, <strong>and</strong> of course it may hit the<br />

target, i + 1.<br />

For drills that focus on acquisition, even if they manage to hit the target, i + 1, we<br />

may question whether they actually provide enough input for real acquisition to<br />

occur. Also, they typically lack the anticipation <strong>and</strong> review that simple codes<br />

provide automatically. When acquisition-type activities undershoot, the result of<br />

course may<br />
