Teaching Average Through Implementing Cognitively Demanding Statistical Tasks


Vuslat Şeker (TURKEY)


The purpose is to investigate how a mathematics teacher implements cognitively demanding statistical tasks (CDST) and how student learning occurs during the implementation of such tasks. The study is a case study in which a mathematics teacher, Betul, was the case. Two 7th grade classes of Betul teacher during statistics chapter were observed. The CDST were prepared by the researcher and implemented in 18 lessons, also the student artifacts were collected for investigating student learning. In this paper, 8 lessons and the student artifacts will be analyzed since the focus is to explain teaching practices about CDST in the context of teaching average concept. The unit of analysis is CDTS; therefore, The Mathematical Task Framework (Stein &Lane,1996) will be used to analyze CDST.
