The purpose of the study was to investigate the effects of mathematics instruction supported by dynamic geometry activities on seventh grade students’ achievements in the area of quadrilaterals, based on their van Hiele geometric thinking levels. The study followed a nonrandomized control group pretest and posttest research design. Participants of the study were 76 seventh grade students. Students in the experimental group worked in a learning environment supported by dynamic geometry software while other students worked in their conventional settings. The results of the study indicated that there is a significant interaction between the effects of method of teaching and van Hiele geometric thinking levels on students’ achievement levels in area of quadrilaterals. In addition, mathematics instruction supported by dynamic geometry activities has significant effects on seventh grade students’ achievement in the area of quadrilaterals. Moreover, the results revealed that students in the dynamic geometry supported instruction group received significantly higher scores in the area of quadrilaterals than students in the traditional instruction group when students are at second level of van Hiele geometric thinking.

The Effects of mathematics instruction supported by dynamic geometry activities on seventh grade students’ achievement in area of quadrilaterals
Özçakır, Bilal; Çakıroğlu, Erdinç; Department of Elementary Science and Mathematics Education (2013)
The aim of this study was to investigate the effects of mathematics instruction supported by dynamics geometry activities on students’ achievement in area of quadrilaterals and students’ achievements according to their van Hiele geometric thinking levels. The study was conducted in a public elementary school in Kırşehir in 2012 – 2013 spring semester and lasted two weeks. The participants in the study were 76 seventh grade students. The study was examined through nonrandomized control group pretest-posttest...
Effect of inquiry-based instruction enriched with origami activities on achievement, and self-efficacy in geometry
Kandil, Semanur; Işıksal-Bostan, Mine (2019-05-19)
The purpose of the study was to investigate the effect of inquiry-based instruction enriched with origami activities on 7th grade students' achievement in reflection symmetry and self-efficacy in geometry. Two classes, instructed by the first author of the paper, were randomly assigned as experimental and control groups. In order to gather data, participants were administered Reflection Symmetry Achievement Test, and Geometry Self-Efficacy Scale as pre-test and post-test. The Analysis of Covariance was perf...
Impact of 5e learning cycle on sixth grade students' mathematics achievement on and attitudes toward mathematics
Pulat, Selma; Bulut, Safure; Department of Educational Sciences (2009)
The purpose of the study was to investigate the impact of 5E learning cycle on sixth grade students’ mathematics achievement on and attitudes toward mathematics. The study was carried out in a public school in one of the towns of the Central Anatolia Region with 28 sixth-grade elementary school students. One group pretest-posttest design was used. Mathematics Achievement Test and Mathematics Attitude Scale were administered to collect the necessary data. The instruction will be applied by the researcher fiv...
Effects of using manipulatives on seventh grade students' achievement in transformation geometry and orthogonal views of geometric figures
Enki, Kerim; Haser, Çiğdem; Department of Elementary Science and Mathematics Education (2014)
The purpose of the present study was to investigate the effects of using manipulatives on seventh grade students’ achievement in transformation geometry and orthogonal views of geometric figures. This study also aimed to investigate students’ views about using manipulatives. The study was conducted in one elementary school in Keçiören district of Ankara in the Spring semester of 2012-2013 academic year. The study employed a static group pretest-posttest research design with 73 seventh grade students. Two cl...
Effects of graphing calculators on eighth grade students' achievement in graphs of linear equations and concept of slope
Önür, Yurdagül; Erbaş, Ayhan Kürşat; Department of Educational Sciences (2008)
The purpose of this study was to investigate the effects of graphing calculators on eight grade students’ achievement in graphing linear equations and concept of slope. Pretest-posttest experimental-control group design was utilized in the study. While the students in experimental group (EG) received instruction about graphs of linear equations and concept of slope with graphing calculators, the students in control group (CG) was taught the same topics without using graphing calculators. There were 27 stude...
