We developed and evaluated a P-CUBE series of block-based, tangible programming tools for beginner programmers, including the visually impaired. We conducted a trial class to create a speech program with P-CUBE3, which included a function to record the operational history data of the programming blocks. We classified the users’ operation patterns using the operation history data obtained in the class and evaluated the results. We propose a method for classifying user operation patterns from the operation history data obtained in the class and visualizing the tendency of block operations using a co-occurrence matrix. We also report the differences in the tendencies of blocking operations based on user characteristics revealed by the proposed method.
