Abstract
Japanese learners of English are said to be relatively familiar with grammar. This is because entrance examinations to universities require a high level of grammatical knowledge. However, there are some typical grammatical errors which the learners continue to make. One of these errors is confusion of the noun clause and the adverbial clause, both of which use the same subordinate conjunction, ifor when. This article attempts to present a rationale for an inductive way of teaching noun clauses and adverbialclauses using subordinate conjunctions “if” and “when” in a Japanese EFL setting.
