The aim of this study is to investigate the effect of making argumentation practices on the conceptual understanding level and decision making styles of pre-service science teachers on socio-scientific subject, genetically modified organisms (GMO). The sample of this study consists of 48 Pre-service science teachers studying in the 2nd grade of the science education department, Faculty of Education, in the 2018-1019 academic year. 24 of the pre-service science teachers are the experimental group and 24 of them are the control group. Case study was used in the study. In the experimental group; within the scope of 5E teaching model; with materials and animations containing Toulmin's argumentation model; the control group was processed with traditional teaching methods. Conceptual understanding levels of Pre-service science teachers, who constitute the experimental and control groups, about GMO before and after the teaching activities, were measured. As a data collection tool in the research; the open-ended question and likert type scale consisting of 12 items, which are based on GMO, based on expert opinions and have scope validity, is the Knowledge Test on Genetically Modified Products of University Students (KTGMOUS), pre-test and post-test. It was applied as a test. In addition, a five-point Likert-type "Decision-Making Styles Scale" consisting of 24 items was applied to the experimental group in the form of pre-test and posttest.

This study examines the impact of argumentation on pre-service science teachers' (PST) conceptual understanding of chemical equilibrium. The sample consisted of 57 first-year PSTs enrolled in a teacher education program in Turkey. Thirty two of the 57 PSTs who participated in this study were in the experimental group and 25 in the control group. The experimental group students learned the concept of chemical equilibrium through argumentation; the control group students learned the same concepts through business as usual (i.e.lectures, supported by laboratory experiments). The intervention lasted for 12 instructional hours, of which 4 were spent in the laboratory. The chemical equilibrium concept test was administered to both groups of students one week after the intervention. The results show that the experimental group students performed significantly better than then control group students on the chemical equilibrium concept test. The mean difference between two groups is 14.026. This difference is statistically significant at (*p< 0.001). However, the control group students performed significantly better on the comprehensive course final exam.

This research aims at investigating the effectiveness of the Predict-Explain-Observe-Discuss-Explain (PEODE) based laboratory work activities on pre-service science teachers’ science process skills. A quasi-experimental research model with pre- and post-test via control group was employed in the research. The semi-experimental study was based on 46 pre-service science teachers enrolled in the primary Science Education Program a state university. In the research, randomly selected two groups were used, one experimental group (EG; n = 22) and one control group (CG; n = 24). While the control group participated in traditional laboratory activities work, the experimental group took part in the PEODE-based laboratory work activities. Laboratory activities were carried out in both groups for a total of 9 weeks, two hours a week. Science process skills test (SPST) measuring five different scientific process skills were presented to them as pre- and post-test in order to assess pre-service science teachers’ science process skills. The test scores were analyzed quantitatively with a statistical analysis program. At the end of the research, while there was no significant differences total score of the SPST, significant statistical differences were found between the experimental and control groups in "Making Operational Comments" and "Designing the Research" sub-skills.

The main purpose of this study was to investigate the effect of the Context-Based Approach (CBA) enriched by Prediction–Observation–Explanation (POE) on 5th grade students’ conceptual understanding of the States of Matter, Heat and Temperature. In this study, quantitative and qualitative data collection methods were employed. The quantitative element used a quasi-experimental design involving a non-equivalent pretest–posttest control group. This research was performed with a total number of 38 (N control group = 18, N experimental group = 20) 5th grade students (aged 10 to 11 years) in a school in a village located in the East Blacksea region in the 2016–2017 academic year. In the study, a two-tier concept questionnaire entitled ‘the States of Matter, Heat and Temperature (SMHTQ)’ and a semi-structured interview were used as data collection tools. In the experimental group, the topics were taught using the CBA enriched with the POE strategy while in the control group the topics were taught using the 5E teaching model (Engage–Explore–Explain–Elaborate–Evaluate) of the constructivist approach. The results indicated that the CBA enriched with the POE strategy was more effective in improving students’ conceptual understanding and reducing students’ alternative concepts than the 5E teaching model on the States of Matter, Heat and Temperature concepts. The results of the study provided helpful information for science teachers and researchers in science/chemistry education since the teaching materials used enriched the learning environment. Similar studies can be applied to different and wider sample groups and concepts.

The aim of this study was to investigate the effects of using a 5Es learning model on the pre-service science teachers? conceptual understanding and science process skills for ?gases and gas laws?. The sample of the study consisted 49 pre-service science teachers enrolled for the ?Science Laboratory Practices-I? course within the department of science education of a Turkish state university. Through a quasi-experimental research method (pre- and post- -test research design), an experimental group was exposed to the 5Es learning model (engage-explore-explain-elaborate-evaluate) with different conceptual change methods/techniques (i.e., worksheets, computer animations, analogies and experiments). A control group was also taught through existing instruction (e.g., experiments, lecture and question?answer). Data were collected through the gas laws test and the science process skills test. The results of partial eta squared (?2) revealed large-size effects for the control (0.61) and experimental groups (0.73). The 5Es learning model was more effective than the existing instruction in overcoming the pre-service science teachers? alternative conceptions of ?gases and gas laws?, as well as in improving their science process skills. The current study recommends that the 5Es learning model be tested with a larger sample throughout a long-term teaching intervention.

The purpose of the current study is to investigate the effect of interdisciplinary approach-based energy instruction on pre-service science teachers’ academic achievement and conceptual understanding regarding the concept of energy. To this end, the current study was designed as a quasi-experimental study in line with the pretest-posttest control group design. The activities related to the concept of energy were conducted by using the interdisciplinary approach and the same activities were conducted by using the methods and techniques based on the existing approaches. A total of 66 pre-service science teachers participated in the study lasting for 10 weeks. In the analysis of the data, ANOVA/Post Hoc Test was used. As a result of the study, it was found that the use of the interdisciplinary instructional approach in teaching the concept of energy increased the pre-service teachers’ academic achievement and conceptual understanding more than the traditional approaches. Thus, it can be suggested that during the instruction of the energy concept, the features of this concept should be taught in a certain developmental order and the interdisciplinary approach should be used in the activities conducted to teach this concept.

AbstractLearning in laboratories for students is not only crucial for conceptual understanding, but also contributes to gaining scientific reasoning skills. Following fast developments in technology, online laboratory environments have been improved considerably and nowadays form an attractive alternative for hands-on laboratories. The study was done in order to reveal pre-service science teachers’ preferences for hands-on or online laboratory environments. Participants of the study were 41 pre-service science teachers who were enrolled in a 13-week course on laboratory applications in science education. Findings showed that more than half of the pre-service science teachers would prefer to use hands-on laboratory environments for both conceptual teaching in their classrooms and to develop their students’ science process skills. The reasons behind their choices are discussed.Keywords: Online lab, hands-on lab, virtual lab, science and technology education, pre-service science teachers.* ADDRESS FOR CORRESPONDENCE: Hasan Özgur Kapıcı , Yıldız Teknik Ünivesitesi, Istanbul, TurkeyE-mail
