The purpose of this study was to investigate the effects of using a dynamic geometry environment (DGE) together with inquiry-based explorations on the sixth grade students' achievements in polygons and congruency and similarity of polygons. Two groups of sixth grade students were selected for this study: an experimental group composed of 66 students (34 boys and 32 girls); and a control group composed of 68 students (35 boys and 33 girls). The students in the experimental group taught with a DGE, while the students in the control group received textbook-based direct instruction. An achievement test was administered as pre-test, post-test, and delayed post-test in both groups. Qualitative data were collected through videotaped classroom observations. The results showed that the DGE together with open-ended explorations significantly improved students' performances in polygons and congruency and similarity of polygons. Furthermore, students in the experimental group showed greater interest and motivation toward learning geometry compared to those in the control group whom often showed lack of interest and curiosity. Also, students' comments and interpretations during lessons and tests were more accurate and advanced in the experimental group as they engage more in the DGE. Moreover, qualitative data suggested that boys showed greater interest in the computer-based learning environment than girls in the experimental groups although no significant gender effect on achievement was found.

The effect on instruction with concrete models on eighth grade students' geometry achievement and attitudes toward geometry
Bayram, Sibel; Bulut, Safure; Department of Secondary Science and Mathematics Education (2004)
The purpose of the study was to investigate the effects of concrete models on eighth grade students̕ geometry achievement and attitudes toward geometry. The study was conducted on 106 eighth grade students in one of the private school in Ankara. The subjects of the study received instruction with concrete models, and by the traditional method. Cooperative learning method and discovery learning method were also used to provide better classroom environment and to create exciting classroom atmosphere for the u...

Aydoğan, Arzu; Erbaş, Ayhan Kürşat; Department of Secondary Science and Mathematics Education (2007)
The aim of this study was to investigate the effects of using a dynamic geometry environment together with open-ended explorations on sixth grade students’ performance in polygons and congruency and similarity of polygons. Two groups of sixth grade students were selected for this study: (1) An experimental group composed of 66 students whom 34 were boys and 32 were girls; and (2) a control group composed of 68 students whom 35 were boys and 33 were girls. While the students in the control group received ins...
The effects of problem-based learning method on 9th grade students’ achievement in geometry
Apaçık, Mükerrem; Bulut, Safure; Department of Secondary Science and Mathematics Education (2009)
The purpose of the study was to determine the effects of problem-based learning (PBL) on 9th grade students’ geometry achievement. The study was conducted in a rural town of Ankara with 44 ninth-grade high school students. The randomized pretest-posttest control group design was used. The experimental group was instructed with hybrid PBL and the control group was instructed with traditional teaching methods. The treatment was given for 4 hours every week for a total of six weeks. Geometry Achievement Test (...

The aims of this study were to investigate the effects of drama based instruction on seventh grade students̕ achievement on geometry (angles and polygons; circle and cylinder), retention of achievement, van Hiele geometric thinking level, attitudes toward mathematics and attitudes toward geometry compared to the traditional teaching; to get the students̕ views related to the effects of drama based instruction on their learning, friendship relations, awareness of themselves, and the role of teacher and stude...
The effects of computer games on primary school students' achievement and motivation in geography learning
TÜZÜN, HAKAN; Yilmaz-Soylu, Meryem; Karakus, Tuerkan; Inal, Yavuz; Kizilkaya, Gonca (Elsevier BV, 2009-01-01)
The implementation of a computer game for learning about geography by primary school students is the focus of this article. Researchers designed and developed a three-dimensional educational computer game. Twenty four students in fourth and fifth grades in a private school in Ankara, Turkey learnt about world continents and countries through this game for three weeks. The effects of the game environment on students' achievement and motivation and related implementation issues were examined through both quan...
