In the literature, there have been research examining different grade levels of students’ understanding of geometric shapes such as triangles and their main elements as well as their auxiliary elements. The purpose of the current study is to investigate preservice middle school mathematics teachers’ (PMSMT) conception of auxiliary elements of triangles. In order to achieve this, the activity sheets about definitions, constructions, and properties of auxiliary elements of triangles were designed and conducted to 23 junior PMSMT. The PMSMT engaged in these activity sheets. The data were collected through their written works and it was analyzed based on the content analysis which is a type of qualitative data analysis technique. It was found that, the PMSMT could effectively define auxiliary elements of triangles. However, they had difficulty in the properties and related theorems about auxiliary elements.

Preservice Middle School Mathematics Teachers’ Knowledge about Students’ Mathematical Thinking Related to Perimeter and Area
Güner, Pınar; Akyüz, Didem (2017-10-01)
The purpose of the current study is to examine preservice middle school mathematics teachers’ knowledge about students’ mathematical thinking related to perimeter and area and determine the consistency between this knowledge and students’ actual mathematical thinking. Case study, one of the qualitative research designs, was used to gain an in-depth understanding of the situation. The study was conducted with four senior preservice middle school mathematics teachers who enrolled in the program of elementary ...
Pre-service middle school mathematics teachers’ pedagogical content knowledge regarding the area of triangles
Bilik, Aslı; Işıksal Bostan, Mine; Department of Elementary Science and Mathematics Education (2016)
The purpose of this study was to investigate pre-service middle school mathematics teachers’ pedagogical content knowledge on the concept of the area of triangles. In this respect, pre-service teachers' pedagogical content knowledge with respect to students' possible misconceptions/ difficulties regarding the area of triangles and the strategies that pre-service teachers employed to overcome these misconceptions/difficulties were examined. To conduct an in-depth investigation regarding the purpose of the st...
Preservice teachers' purposes of utilizing concrete materials
Tat, Emel Topbas; Bulut, Safure (2010-02-08)
The purposes of utilizing concrete materials in mathematics courses are not clear for some teachers. For this reason the purpose of the study is to determine preservice teachers’ opinions about using concrete materials in teaching mathematics. This study was designed as a qualitative study. Participants of the study consisted of 45 preservice elementary mathematics teachers. According to the results of the study, participants’ purposes to use concrete materials in school mathematics courses are collected un...
Integrating Light to Foundation Course as a Basic Design Element
Özgen Koçyıldırım, Dalsu (2015-10-15)
Basic Design, the rst year foundation course of METU’s Industrial Design Department, leads students gradually from two-dimensional to three-dimensional abstract compositions. As the assignments gain volume, students experiment with the play of light and shadow that is essential for volume perception and crucial for the professional development of prospective industrial designers. Through the years of teaching Basic Design, authors observed that, students have tendency to accept light as a default and uncont...
Preservice Mathematics Teachers’ Types of Mathematical Thinking: Use of Representations, Visual-Spatial Abilities and Problem Solving Performances
Olgun, Beyza (null; 2017-02-05)
The main purpose of this study was to examine preservice mathematics teachers’ types of mathematical thinking and to investigate whether there are any differences between different types of thinkers based on their problem solving performances, use of representations and visual-spatial abilities. The sample of the study consisted of 113 preservice mathematics teachers in a private and four public universities. The results showed that although problem solving performances were similar for each type of mathema...
