Abstract The concept of acid bases is a classical area where students have learning difficulties. Previous studies have focused on studies of misconceptions about acid basin and methods of eliminating misconceptions. Until recently, however, students still have misconceptions and complain about learning difficulties. In addition, during the recent studies on acid bases, science teachers have mostly described the definitions of the three acid bases models in a similar way. Most of the existing acid base concept test items are presented in the form of presenting the given problem situation and checking the view items developed according to the conceptual model. However, this type of testing tool is difficult to understand various types of thinking and concept of students and responds to limited views, so it has limitations in understanding student concept types. The purpose of this study is to measure students' conceptual models by using descriptive questions and visual representations of particles in various contexts, unlike previous tools for measuring acid base concepts. This open - ended conceptual inspection tool is expected to give meaningful implications to the student 's conceptual model.
