One of the main points of the Course of Study, a national syllabus for formal education at secondary schools in Japan announced in 2017 is that the development of “the ability to think, make judgements, and express themselves” (hereinafter referred to as “the ability to think”) must be interrelated with the skills to be acquired not only in each subject area but also in a cross-curricular perspective. The aim of this study is to prepare for the development of a summative assessment to measure the achievement of the ability to think fostered through cross-curricular learning. First, this study clarified the areas of the ability to think to be measured based on the Can-do Statements of the ability to think, which embody the goals of the ability to think extended from the theoretical framework of “thinking skills” shared by major subjects. Second, A prototype version of the assessment items was developed. Third, based on the results of the analysis of verbal protocol data during answering items and item analysis of its quantitative response data, the authors attempted to collect evidence of the validity of the items and implications for item revision.
