  abstract  = {In this article, we propose a model for an understanding process that learners can use while studying programming. We focus on the "small step" method, in which students learn only a few concepts for one program to avoid having trouble with learning programming. We also analyze the difference in the description order between several C programming textbooks on the basis of the model. We developed a tool to detect "gaps" (a lot of concepts to be learned in a program) in programming textbooks.},
