Grammar concepts are among the fundamental concepts of Turkish teaching. Improper teaching of them may cause the rise of certain problems in the teaching of high-level lingual concepts. What is intended herein is to identify if 6th Grade students do encounter misconceptions while learning grammar concepts. Data of the study have been obtained via semi-structured interview technique. Interviews were made in the spring term of the 2011 to 2012 academic year with 20 students at their schools in Usak province. Each student was interviewed separately for around 25 min. It has been ascertained as a result of the study that, students do have misconceptions related to grammar, and that they encounter difficulties in describing the concepts in question.
