A method for teaching English grammar was systematized by classifying textbook sentences based on their “constructions” instead of their grammatical items. The Japan Association of Applied Semiotics for English Teaching (JAASET) method was referred to in systematizing this teaching method, which applies a set of symbols onto English and Japanese sentences to visualize the differences in their constructions in a unified manner. Thus, different grammatical items could be presented in a simple framework to enhance the students’ understanding. It was also clarified that particular types of constructions appear more frequently than others in textbooks. This imbalance may lead to students’ imbalanced exposure to different construction types, which results in students’ imbalanced acquisition of them. This study was based on teaching first-year students in junior high school classes.
