Effects of Dynamic Geometry Activities on Seventh Graders’ Learning on Area of Quadrilaterals
Özçakır, Bilal; Çakıroğlu, Erdinç (2019-12-01)
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 ot...
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...
Effect of case based learning on 10th grade students’ understanding of gas concepts, their attitude and motivation
Yalçınkaya, Eylem; Boz, Yezdan; Department of Secondary Science and Mathematics Education (2010)
The main purpose of the present study was to investigate the effect of case-based instruction based on conceptual change conditions to overcome 10th grade students’ misconceptions related to gas concepts. Moreover, the effect of this method on students’ attitudes toward chemistry and their perceived motivation was explored. The study was carried out during the 2008-2009 academic year at both a state high school and an Anatolian high school. A total of 128 tenth grade students were the participants of the st...
Effects of web-based multimedia annotated vocabulary learning in context model on foreign language vocabulary retention of ıntermediate level english langauge learners
Baturay, Meltem Huri; Yıldırım, Soner İ.; Department of Computer Education and Instructional Technology (2007)
The aim of this study was to investigate the effects web-based multimedia annotated vocabulary learning in context model and in spaced repetitions on vocabulary retention of intermediate level English language learners. The research study encompassed two main faces which was related to development of the material and implementation of it. In WEBVOCLE, which stands for web-based vocabulary learning material, the contextual presentation of vocabulary were enriched with audible online dictionary, pictures and ...
Effects of epistemologically enhanced instruction on ninth grade students’ physics related personal epistemology and achievement in physics
Özmen, Kübra; Özdemir, Ömer Faruk; Department of Secondary Science and Mathematics Education (2017)
This study investigated the effect of epistemologically enhanced instruction on ninth grade students’ physics related personal epistemologies and physics achievement on heat and temperature unit. The participants of the study were 186 (109 female and 77 male) ninth grade students at one Anatolian teacher training high school in Ankara. For the current study, a quasi-experimental with matching only pretest-posttest control group research design was adopted. Six classes in the school were randomly assigned to...
