Concrete manipulatives and dynamic geometry software (DGS) are both commonly used for geometry education in elementary and middle schools. This study sets out to understand which of the two approaches was better in improving the conceptual understanding of quadrilaterals for fifth graders. A pre-/post-test design was conducted in which the same topic was taught by the same teacher to three groups of students, with each group receiving a different type of instruction, namely concrete manipulative based, DGS based and paper-and-pencil based. The initial levels of the students were almost equal as determined by pre-tests. Quantitative analysis of post-test scores revealed that the DGS based approach contributed most to students' geometrical understanding, followed by the concrete manipulative based approach. Interviews and qualitative analysis were also conducted to gain deeper insights into students' reasoning and the effect of different instruction types. The interview results revealed that more students in the DGS group could overcome the misconceptions and difficulties than the students in other groups.

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...
The Effects of Using Dynamic Geometry on Eighth Grade Students' Achievement and Attitude towards Triangles
Samur Turk, Halime; Akyüz, Didem (2016-07-01)
This study investigates the effects of dynamic geometry based computer instruction on eighth grade students' achievement in geometry and their attitudes toward geometry and technology compared to traditional instruction. Central to the study was a controlled experiment, which contained experimental and control groups both instructed by the same teacher. 36 eight grade students from a middle school located in a rural area in Turkey participated in this experiment. None of the students had past experience in ...
The Effects of dynamic geometry use on eighth grade students’ achievement in geometry and attitude towards geometry on triangle topic
Samur, Halime; Akyüz, Didem; Department of Elementary Science and Mathematics Education (2015)
The purpose of this study was to investigate the effect of dynamic geometry based computer instruction on eighth grade students’ achievement in geometry, attitudes toward geometry and technology compared to traditional instruction. Moreover, it was aimed to get the students’ ideas about the effects of computer based instruction and to interpret their learning process. The study was quasi-experimental design that includes experimental and control groups. The sample of the study was 36 eighth grade students (...
Analysis of analogy use on function concept in the ninth grade mathematics textbook and classrooms
Ünver, Emel; Ubuz, Behiye; Department of Secondary Science and Mathematics Education (2009)
The primary objective of the current study was to examine how analogies are used on function concept in the ninth grade mathematics textbook and classrooms. Using qualitative research procedure comprising textbook analysis and classroom observations, a picture was developed of how analogies used on function concept in ninth grade mathematics textbook and classrooms. One mathematics textbook, the primary source for observed classes was selected and analyzed for the study. Chapter entitled as “functions” in t...
Generating functions and their applications
Bilgin, Begül; Doğanaksoy, Ali; Department of Cryptography (2010)
Generating functions are important tools that are used in many areas of mathematics and especially statistics. Besides analyzing the general structure of sequences and their asymptotic behavior; these functions, which can be roughly thought as the transformation of sequences into functions, are also used effciently to solve combinatorial problems. In this thesis, the effects of the transformations of generating functions on their corresponding sequences and the effects of the change in sequences on the gene...
