The Effect of The Common Knowledge Construction Model-Oriented Education on Sixth Grade Students' Views on The Nature of Science
(Sci Methodical Ctr-sci Educologica, 2017) Bakirci, Hasan; Calik, Muammer; Cepni, Salih
The aim of the present research was to explore the effect of the Common Knowledge Construction Model (CKCM)oriented education on sixth grade students' views on the Nature of Science (NOS) and to compare it with the existing learning model (5Es learning model). The research was conducted with a total of 76 students (38 by 38-for experimental and control groups) in 2013-2014 school year. Within a quasi-experimental research design, the Views of Nature of Science Questionnaire (VNOS) and the Student Interview on the Nature of Science Aspects (SINOSA) were used for data collection. Quantitative data from the VNOS were exposed to independent t-test while qualitative data from the interview protocol were analyzed using content analysis. Results of pre-test and pre-interview denoted that both groups properly constructed 'empirical' aspect of the NOS while the other aspects of the NOS were naive and transitional levels. After the intervention, it was found that the control group's views of the NOS, except for the empirical aspect, were transitional level whilst those of the experimental group were informed level. Further, it was elicited that the experimental group performed the highest change in 'imaginary and creative' aspect of the NOS.
Effects of 'environmental Chemistry' Elective Course Via Technology-Embedded Scientific Inquiry Model on Some Variables
(Springer, 2014) Calik, Muammer; Ozsevgec, Tuncay; Ebenezer, Jazlin; Artun, Huseyin; Kucuk, Zeynel
The purpose of this study is to examine the effects of 'environmental chemistry' elective course via Technology-Embedded Scientific Inquiry (TESI) model on senior science student teachers' (SSSTs) conceptions of environmental chemistry concepts/issues, attitudes toward chemistry, and technological pedagogical content knowledge (TPACK) levels. Within one group pre-test-post-test design, the study was conducted with 117 SSSTs (68 females and 49 males-aged 21-23 years) enrolled in an 'environmental chemistry' elective course in the spring semester of 2011-2012 academic-years. Instruments for data collection comprised of Environmental Chemistry Conceptual Understanding Questionnaire, TPACK survey, and Chemistry Attitudes and Experiences Questionnaire. Significant increases in the SSSTs' conceptions of environmental chemistry concepts/issues, attitudes toward chemistry, and TPACK levels are attributed to the SSSTs learning how to use the innovative technologies in the contexts of the 'environmental chemistry' elective course and teaching practicum. The study implies that the TESI model may serve a useful purpose in experimental science courses that use the innovative technologies. However, to generalize feasibility of the TESI model, it should be evaluated with SSSTs in diverse learning contexts.
Improving Science Student Teachers' Self-Perceptions of Fluency With Innovative Technologies and Scientific Inquiry Abilities
(Springer, 2015) Calik, Muammer; Ebenezer, Jazlin; Ozsevgec, Tuncay; Kucuk, Zeynel; Artun, Huseyin
\ The aim of this study was to investigate the effects of "Environmental Chemistry" elective course via Technology-Embedded Scientific Inquiry (TESI) model on senior science student teachers' (SSSTs) self-perceptions of fluency with innovative technologies (InT) and scientific inquiry abilities. The study was conducted with 117 SSSTs (68 females and 49 males-aged 21-23 years) enrolled in the "Environmental Chemistry" elective course in spring semester of 2011-2012 academic year in a Turkish University. Within a simple (causal) experimental design, Innovative Technology Fluency Survey and the SSSTs' environmental research papers were employed to collect data. The results indicate that the "Environmental Chemistry" elective course via the TESI model improved the SSSTs' self-perceptions of fluency with InT and the scientific inquiry abilities. In light of the results, it is recommended that an undergraduate course for improving the SSSTs' higher-order scientific inquiry abilities and preparing academically papers should be devised and added into the science teacher-training programmes.
