Matematiksel İspat ve Matematiksel Muhakemenin Gelişimi Üzerine Bir İnceleme

This study investigated mathematical proof and adjudicating.The information about
concept of mathematical proof and related examples are given levels of
prekindergarten years, elemantary school and high school in the National Council of
Teachers of Mathematics principles and standards. The development of reasoning is
investigated during the years of preschool, elementary and high school. Concepts of
classification, matching, comparison are basic concepts for children to develop reasoning
during preschool years. On this basis, suggestions were put forward, and the formation
of resonable thinking were asked for. At the first stage of elementary education, an
individual is at the eriod of concrete thinking. In this direction, relationshipsof pieceand-
whole are dealt with and thus examples were given for the principles of induction.
At the second stage, students are asked to form hypothesis about generalizations and
and to evalluate these hypothesis usşng standards of prooving. Years of high school are
are the ones during which the process of concrete thingking develops and during these
years deduction and induction skills arfe formed. In this direction, kinds of prooving
were examined and sşuggestions were put forward.
