This study investigates the effect of methods of instruction (inquiry-based versus lecture instruction) and their interactions with students’ cognitive styles (field-dependent, field-mixed, and field-independent) and with other independent variables on 11th grade students’ physics achievement in and attitude toward electric circuits concepts in central district of Aydın. Lesson plans, instructional materials were developed for the inquiry-based instruction. Teachers’ regular classroom practices were accepted as lecture method. Physics achievement test, physics attitude scale, observation checklists, and GEFT were used as data collection instruments. Treatment was implemented to 298 11th grade students in central district of Aydın. Physics achievement test and physics attitude scale were administered to the students as pre and post tests while GEFT was administered only as pre test. MANCOVA was used as statistical analysis method to analyze data. The dependent variables of this study were the achievement (PSTACH) and attitude (PSTATT) scores of the students. The covariate and gender were used to statistically equalize the students’ characteristics. Group membership with respect to two groups (inquiry or lecture groups) was named here as “MOI; methods of instruction” (2 level categorical) and used as fixed factor of this study with the other group membership variables, students’ physics achievement pretest scores (PREACH), physics attitude pretest scores (PREATT), School, previous physics course grades (PPCG), cognitive style (CoS, 3 level categorical), and the interaction terms of MOI*PREACH, MOI*PPCG, PREATT*MOI*PPCG*CoS, MOI*PPCG*CoS, PREACH*School, and PREACH*PREATT. In general, inquiry instruction was effective than the lecture instruction with respect to PSTACH in electric circuits subject. However, there was not a significant difference in effectiveness of both methods in improving students’ attitudes toward electric circuits subject. In essence, each method of instruction was not effective on improving students’ attitudes toward electric circuits subject. Although, this study could not find any statistically significant interaction effect of MOI and other independent variables on students’ PSTATT scores, practical significance was investigated for the interaction terms.

An assesment of an on-line course environment based on the perceptions of students and the instructor : a case study Gürbüz, Tarkan; Yıldırım, İbrahim Soner; Department of Computer Education and Instructional Technology (2004) The purpose of this study was to explore the factors that contribute to online collaboration in a web-based course by investigating the impact and the potential of an online learning environment in terms of both the students' and instructor̕s perceptions about learner benefits, learner support, motivation, computer mediated communication, and group work. A mixed methods case study design was thought to be appropriate to match the purpose of the study, thus a combination of components normally found in descr...
Students understanding of limit concept: an apos perspective Çetin, İbrahim; Özden, Yaşar; Department of Computer Education and Instructional Technology (2009) The main purposes of this study is to investigate first year calculus students’ understanding of formal limit concept and change in their understanding after limit instruction designed by the researcher based on APOS theory. The case study method was utilized to explore the research questions. The participants of the study were 25 students attending first year calculus course in Middle East Technical University in Turkey. Students attended five weeks instruction depending on APOS theory in the fall semester...
The influence of argumentation based instruction onsixth grade students' attitudes toward science, conceptual understandings of physical and chemical change topic and argumentativeness Oğuz Çakır, Bahriye Zühal; Çapa Aydın, Yeşim; Department of Educational Sciences (2011) The purpose of this study was to investigate the influence of argumentation based instruction on sixth grade students‟ attitudes toward science, development of conceptual understanding about physical and chemical change topic, and argumentativeness. This study was carried out during 2010-2011 spring semester at a public elementary school in Ankara. A total of 65 sixth grade students from two intact classes were theparticipants of this study. The sample was chosen conveniently. Students in the experimental g...
The Comparative Effects of Prediction/Discussion-Based Learning Cycle, Conceptual Change Text, and Traditional Instructions on Student Understanding of Genetics Yilmaz, Diba; Öztekin, Ceren; Sungur, Semra (Informa UK Limited, 2011-01-01) The present study examined the comparative effects of a prediction/discussion-based learning cycle, conceptual change text (CCT), and traditional instructions on students' understanding of genetics concepts. A quasi-experimental research design of the pre-test-post-test non-equivalent control group was adopted. The three intact classes, taught by the same science teacher, were randomly assigned as prediction/discussion-based learning cycle class (N = 30), CCT class (N = 25), and traditional class (N = 26). ...
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 ...
