My area of research is mathematics education, children's mathematical thinking
Journal of Computers in Mathematics and Science Teaching Vol. 22, No. 1 (2003) pp. 43–56
This study compared the effect of computer versus concrete manipulatives for the learning of two-dimensional geometry. Participants were 93 4th- and 5th- grade students. A pretest, treatment, and posttest experimental design was used. The pre and...
World Conference on Educational Media and Technology 2004 (2004) pp. 4293–4302
This study has important implications for design of microworlds such as Hypergami, and Logo which use interactivity to help students learn spatial mental models involving math and science. This study tested the hypothesis that interactively rotating ...
Technology Leadership and Supervision: An Analysis Based on Turkish Computer Teachers' Professional Memories
Technology, Pedagogy and Education Vol. 18, No. 1 (March 2009) pp. 45–58
This study examined Turkish computer teachers' professional memories telling of their experiences with school administrators and supervisors. Seventy-four computer teachers participated in the study. Content analysis of the memories revealed that...
EdMedia: World Conference on Educational Media and Technology 2003 (2003) pp. 2798–2803
Does interaction with shapes help build internal spatial representations? This has implications for science, math, engineering and other fields. This study tested the hypothesis that interactive manipulation of a shape improves mental rotation....
World Conference on Educational Media and Technology 2008 (Jun 30, 2008) pp. 3407–3412
The purpose of this study was to analyze the professional memories of Turkish computer teachers telling of their experiences with the school administrators and supervisors. Participants were 74 computer teachers. A total of 120 themes were...
Educational Technology & Society Vol. 10, No. 4 (2007) pp. 131–142
This study, using content analysis technique, examined the types of job-related problems that the Turkish computer teachers experienced and the types of social support provided by reciprocal discussions in an online forum. Results indicated that...
Computer-Game Play as Imaginary Stage for Reading: Pentop computers, hardcopy books and spatial situation models
World Conference on Educational Media and Technology 2011 (Jun 27, 2011) pp. 575–582
This study investigated the implicit effects of interactive map books (patent pending), with computer games embedded in books using PenTop computers, (versus regular books) on reading comprehension and retention of spatial details from stories. Two...
Put the story back into story problems: Effect of causal narrative on mathematical word problem comprehension
World Conference on Educational Media and Technology 2011 (Jun 27, 2011) pp. 3629–3634
This study investigated whether combining causal with mathematical elements improves mathematical word problem performance, providing a more meaningful context to construct better situation models. Seventy-two undergraduate students majoring in...
Journal of Educational Computing Research Vol. 32, No. 2 (2005) pp. 93–111
This study has important implications for microworlds such as Logo, HyperGami, and Newton's World, which use interaction to learn spatial mental models for science, math, geometry, etc. This study tested the hypothesis that interactively rotating ...
Development and Evaluation of a Case-Based Digital Learning Tool about Children's Mathematical Thinking for Elementary School Teachers (L-TEST)
European Journal of Teacher Education Vol. 32, No. 2 (May 2009) pp. 151–165
It is important for teachers of mathematics to know how pupils react to certain mathematical situations and what these reactions imply, in order to design more effective instructional environments based on their learning needs. This study reports...
Development of a Digital Learning Tool about Children’s Mathematical Thinking for Elementary School Teachers
World Conference on Educational Media and Technology 2006 (June 2006) pp. 3056–3061
The purpose of this paper is to report the development processes of a digital learning tool with elementary school students and its use by elementary school teachers to learn about children's mathematical thinking. First, elementary school students...
Turkish Online Journal of Educational Technology Vol. 12, No. 3 (July 2013) pp. 33–38
Mathematical skills are becoming increasingly critical for achieving academic and professional success. Developmental dyscalculia (DD) is a childhood-onset disorder characterized by the presence of abnormalities in the acquisition of arithmetic...
Pre-service classroom teachers’ learning of spatial skills through geometric transformations – U.S.A and Turkey
World Conference on Educational Media and Technology 2008 (Jun 30, 2008) pp. 5709–5713
This study investigated how elementary education pre-service teachers in Turkey and the United States learned geometric transformations from structured activities using an interactive computer program, and how these activities transferred to a non...
Stills, not full motion, for interactive spatial training: American, Turkish and Taiwanese female pre-service teachers learn spatial visualization
Computers & Education Vol. 52, No. 1 (January 2009) pp. 201–209
This study investigated how female elementary education pre-service teachers in the United States, Turkey and Taiwan learned spatial skills from structured activities involving discrete, as opposed to continuous, transformations in interactive...
