The difference between children and adults
is that children want to absorb everything they learn, but adults may not. They
often take the attitude of what I call selective learning. So for instance, in
a business English class, you introduce the expression of, “Mr. A is not in the
office. May I take a message for you?” and a student whose job is to monitor
the merchandise inventory of a warehouse may encounter a few chances to use the
sentences.
Intuitively, selective learning takes a learning
curb that is skewed to right. It means there is a heavier knowledge
concentration towards zero. As the level of knowledge advances the volume of
people who know the knowledge decreases.
By the way, it may not be the purpose of
the teacher to require students to reproduce exactly what is taught. Yes, this statement
is a challenge to TESOL because it implies “not to expect students to reproduce
what they learn exactly in the way they learn.” Adult students are free to
build on what they learn. In fact, such attitudes are recommended. A question is,
“How will the teacher know students have learned?” An answer to this question is
that there is more than one way to assess how knowledge is acquired. In fact,
the discussion is a Second Language Assessment topic of assessing learning in qualitative
ways. Qualitative ways mean assessing in writing and quantitative ways mean assessing with grades.
My question is, “Do adult learners study
English to get good grades or to use knowledge in their work?” To me, the
answer is the latter, and if so, you should aim for a class where students can
build on what they learn and express how they are going to use the knowledge.
