Abstract

There are opinions about approaching the proof in mathematics education need
to change as providing students to understand the mathematical proof rather
than developing formal mathematical proof skills. In this context, proofs
without words described as informal proofs can be used in proof teaching. The
purpose of this study is to investigate the processes of high school students
to do proofs without words. This study was designed as the case study. This
study was conducted in a high school in Turkey. Consequently, activities of
proof without words that allow the student to take an active role in the proof
process can be presented as an alternative method in proof teaching and the
proof without words can be used for teaching students the stages of proof
process. It is necessary for teachers to be aware of the proof process stages
and guide the students.

Keywords
