A Development Research on Teaching Unit about Statistics Education: Presentation of Teaching Unit Raising Critical Thinking for a Decision-Making Skill

Abstract

　　 The purpose of this paper is to construct a framework of statistical thinking and to develop teaching unit about the statistics education.

　　 For this purpose, the author clarified a way of statistical thinking in order to decide a view on a development of teaching unit about statistics education, and considered on phenomena caught statistically and critical thinking for catching them.

　　 As a result, the author classified characteristics of the phenomena caught statistically into three, concreteness, operativity and variable tendency, and critical thinking into three, aspirant thinking, reflective thinking and analytic thinking.  Through placing three characteristics on each apex of a triangle and linking their apices with each critical thinking, the author proposed the framework on a way of statistical thinking which attach great importance to critical thinking.  Finally, the author developed teaching unit “Estimate of the Number” about sample survey, made development of classes and analyzed each development through the framework on a way of statistical thinking.
