| Outline of Final Research Achievements |
This study aims to clarify the difficulty of students' understanding of algebraic expressions used in scenes of students' equations and propose learning and teaching to overcome the difficulty. Among the problems that were asked in the National Academic Assessment, we focused on the problem of distributing origami to students, where the correct answer rate was low.In this study, we conducted a questionnaire survey and interview survey for 1st to 3rd grade students at two public junior high schools and summarized the understanding of algebraic expressions of the students who can not formulate the equation in the problem.
As a result, the following three aspects were revealed. (1) letter as object replacing the word of the problem sentence, (2) letter as object replacing the numerical value based on the meaning of the numerical value, and (3) letter replacing the object itself.
