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.

Sevgi, Sevim; Berberoğlu, Halil Giray; Department of Secondary Science and Mathematics Education (2009)
The purpose of study is to investigate the effects of school characteristics on students’ mathematics achievement across Turkey by analyzing the data collected from school questionnaire, student background questionnaire and mathematics achievement test in Trends in International Mathematics and Science Study 2007. The analyzed sample was comprised of 4,498 students in 146 schools. Student level factors were highest level of education of either parent, students speak the language of test at home, students’ p...
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...
A modeling study : the interrelationships among elementary students’ epistemological beliefs, learning enviroment perceptions, learning approaches and science achievement
Uysal, Emel; Eryılmaz, Ali; Department of Secondary Science and Mathematics Education (2010)
This study is aimed to explore the relationships among elementary students’ epistemological beliefs of science, perceptions of learning environments, learning approaches and science achievement. For this purpose, a model of the associations among these variables was proposed and tested by structural equation modeling. In this model, it was hypothesized that a) students’ perceptions of their learning environments would directly influence their epistemological beliefs of science and learning approaches, b) st...
Implementation of case-based instruction on electrochemistry at the 11th grade level
Kondakçı, Esen (2017-10-01)
This study aims to compare the effectiveness of case-based instruction over traditional instruction in improving 11th grade students' understanding of electrochemistry concepts, attitudes toward chemistry, chemistry self-efficacy beliefs, and motivation to learn chemistry. In total, 113 students (47 males and 66 females) from three high schools participated in this study. Two of the classes from each school were randomly assigned to be either the experimental or control group. The experimental group was ins...
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...
