Abstract
This action research paper examines the Japanese modified output for questions to beginner-intermediate learners. Through the teaching practices at Akita International University (AIU), adaptation of language should be used according to the level of learners. In particular, the adjustment of difficulty and vagueness of questions will be discussed based on six identified reactions from learners (i.e., proper response, single-word response, nodding, mistaken response, confusion, and no response). The basic sentence structures of Japanese were used as a guideline for judgment along with applied linguistic theories. As a result, adjustments to questioning were made to be as simple, natural, and objective as possible. This action research paper will be a guide for questioning in future classrooms.
