This thesis presents content-related and construct-related validity evidence for science sub-tests within Student Selection Test (SST) in Turkey via underlying the content, cognitive processes, item characteristics, factorial structure, and group differences based on high school type. A total number of 126,245 students were present in the research from six type of school in the data of SST 2006. Reliability Analysis, Item Analysis, Principle Component Analysis (PCA) and one-way ANOVA have been carried out to evaluate the content-related and construct-related evidence of validity of SST. SPSS and ITEMAN programs were used to conduct the above-mentioned analyses. According to the results of content analysis, science items in the SST 2006 found to be measuring various cognitive processes under knowledge, understanding and problem solving cognitive domains. Those items loaded under three factors according to PCA findings which were measuring very close dimensions. Moreover, a threat to validity was detected via one-way ANOVA due to significant mean difference across high school types.

Scientific epistemological beliefs, perceptions of constructivist learning environment and attitude towards science as determinants of students approaches to learning
Özkal, Kudret; Öztekin, Ceren; Department of Elementary Science and Mathematics Education (2007)
The purpose of this study was to investigate scientific epistemological beliefs, perceptions of constructivist learning environment, attitude towards science, prior knowledge and gender as determinants of students’ approaches to learning. This study was carried out in 2005-2006 Spring Semester. One thousand, one hundred and fifty two eighth grade students from seven public schools in Çankaya, a district of Ankara participated in this study. Epistemological Beliefs Questionnaire, Constructivist Learning Envi...
The Contribution of Cognitive and Metacognitive Strategy Use to Students Science Achievement
Akyol, Gülsüm; Öztekin, Ceren; Sungur, Semra (Informa UK Limited, 2010-01-01)
This study examined the differences in the level of 7th-grade Turkish students' cognitive and metacognitive strategy use (rehearsal, elaboration, organization, critical thinking, and metacognitive self-regulation) in science and investigated the contribution of cognitive and metacognitive strategy use to students' science achievement. The present study also explored the relationships between students' background characteristics (gender, prior knowledge, socioeconomic status) and their cognitive and metacogn...
Measuring striving for understanding and learning value of geometry: a validity study
Ubuz, Behiye (Informa UK Limited, 2017-01-01)
The current study aimed to construct a questionnaire that measures students' personality traits related to striving for understanding and learning value of geometry and then examine its psychometric properties. Through the use of multiple methods on two independent samples of 402 and 521 middle school students, two studies were performed to address this issue to provide support for its validity. In Study 1, exploratory factor analysis indicated the two-factor model. In Study 2, confirmatory factor analysis ...
INVESTIGATING PLANE GEOMETRY PROBLEM-SOLVING STRATEGIES OF PROSPECTIVE MATHEMATICS TEACHERS IN TECHNOLOGY AND PAPER-AND-PENCIL ENVIRONMENTS
Koyuncu, Ilhan; Akyüz, Didem; Çakıroğlu, Erdinç (Springer Science and Business Media LLC, 2015-08-01)
This study aims to investigate plane geometry problem-solving strategies of prospective mathematics teachers using dynamic geometry software (DGS) and paper-and-pencil (PPB) environments after receiving an instruction with GeoGebra (GGB). Four plane geometry problems were used in a multiple case study design to understand the solution strategies developed by 2 prospective teachers. The results revealed that although the participants mostly used algebraic solutions in the PPB environment, they preferred geom...
Mathematical Knowledge for Teaching the Function Concept and Student Learning Outcomes
Hatisaru, Vesife; Erbaş, Ayhan Kürşat (Springer Science and Business Media LLC, 2017-04-01)
The purpose of this study was to examine the potential interrelationships between teachers' mathematical knowledge for teaching (MKT) the function concept and their students' learning outcomes of this concept. Data were collected from two teachers teaching in a vocational high school and their students through a function concept test for teachers and students, follow-up interviews with teachers, and classroom observations. Findings indicated that teachers' MKT and students' learning outcomes were related to...
