The purpose of this study is to investigate the effects of principles aiming to reduce extraneous cognitive load in learning from goal based scenario designed multimedia learning environment for learners having different working memory capacities. In addition, the effects of goal based scenario and the principles of cognitive load theory on students’ perception, motivation and satisfaction has been explored. Two versions of the multimedia were developed for this study. In the first version (+CLT), the principles such as split attention, multimedia, modality, redundancy, coherence and signaling was applied. In the second version (-CLT), these principles were violated. Mixed method was used and two studies were conducted for this study. The first study was conducted with 82 ninth grade students from one of the Anatolian High School in Ankara. However, the participants’ working memory capacities were found very close to each other. Therefore, the second study was conducted with 54 11th grade students having different working memory capacity from the same school. The result of the first study showed that the cognitive load principles aim at reducing extraneous cognitive load increased learning gains, decreased invested mental effort and affected students’ motivation and satisfaction in positive ways. On the other hand, when cognitive load principles were not considered, this decreased learning gains, increased invested mental effort and affected students’ motivation and satisfaction in negative ways. The result of the second study showed that the only difference between high and low WMC students found on the number of errors made in sequencing meiosis sub phases in favor of the first version (+CLT). This might be explained by the task characteristics in that the difference between high and low WMC individuals can be observed when task demanded attention. It can be concluded that students benefited from the cognitive load principles reducing extraneous cognitive based on the findings of both studies.

The effect of the web based asynchronous teaching method course on the pre-service teachers' achievement, metacognition, and attitudes towards computer, www and web based course Topçu, Abdullah; Ubuz, Behiye; Department of Secondary Science and Mathematics Education (2005) This study aimed to explore the effects of instructional methods in the asynchronous web-based أScience and Math Teaching Methods Courseؤ on pre-service teachers̕ achievement, metacognition, and attitudes towards computer, WWW, and the web-based course. It was conducted with two groups, total of 63 third grade pre-service teachers, and one instructor (the researcher), in the Elementary Education Department at Bosphorus University in the academic year of 2003-2004. The Instructor used ̀Direct Instructioǹ me...
Factors Affecting Preservice Mathematics Teachers' Decisions on Probability Teaching Özaytabak, Emel; Bulut, Safure; Department of Secondary Science and Mathematics Education (2004) The purpose of this study was to examine the factors affecting preservice mathematics teachers̕ decisions on probability teaching. The sample of the study was 248 preservice mathematics teachers from Gazi University, Hacettepe University, and Middle East Technical University. According to the gender the number of females and males were 170 and 78 respectively. To obtain necessary data for the study, the following measuring instruments were used: (1) Probability Achievement Test (PAT); (2) Probability Miscon...
The Effects of a professional development program on physics teachers’ classroom practices Oktay, Özlem; Eryılmaz, Ali; Department of Secondary Science and Mathematics Education (2015) The purpose of the study is to examine the effects of a professional development (PD) program on in-service physics teachers’ classroom practices. Changes in teachers’ practices were investigated in terms of four dimensions: content/skill/ misconception, teaching strategy, material/technology, and assessment. Qualitative research methodology was used in the study, and a case study was combined with action research. Data were collected from seven participating teachers (1 male, 6 female) and their 9th grade ...
An assessment of preservice teachers' technology perception in relation to their subject area Tınmaz, Hasan; Kiraz, Ercan; Department of Educational Sciences (2004) The purpose of this study is to explore the factors affecting a preservice teacher̕s perception of technology in relation to subject areas. Study focused on six hundred and ninety six senior preservice teachers (405 female, 288 male, and 3 not stated) from eight different subject areas of Burdur Faculty of Education, Süleyman Demirel University in Turkey in 2003-2004 Spring semester. A none-experimental survey research design was employed by administrating a Technology Perception Scale (TPS) and a Computer ...
A investigation of English language teachers' attitudes toward computer technology and their use of technology in language teaching Karakaya, Kadir; Seferoğlu, Gölge; Department of English Language Teaching (2010) This study aimed at investigating the attitudes of English language teachers in Turkey toward computer technology and the extent to which they use technology in language instruction. The data were collected from a sample of English teachers working at public schools all throughout Turkey. In order to ensure triangulation and complementarity, mixed methods research was used combining both quantitative and qualitative research methods. A questionnaire and semi-structured, face-to-face interview were used in o...
