    The effect of deduction and induction methods used in modelling current environmental issues with system dynamics approach in science education
    (Ozgen Korkmaz, 2020) Nuhoğlu, H.
    The main goal of this research is to study the effect of modelling with system dynamics on learning. Specifically, this research studies if using inductive or deductive learning methods applied during modelling with system dynamics has any effect on problem solving skills of students. This research has three other goals: Firstly, the successful application of system dynamics approach in teaching environmental topics. Secondly, helping students to be aware of the environmental problems. Thirdly, helping students to build solution-oriented system dynamics models. An experimental design without control group with pretest/posttest is used in the research. The sample of the research consists of 40 students at 7th grade. Experiment continued an hour per week for the entire semester of 14 weeks. The students in the experiment group 1 developed their models using inductive method. The students in the experiment group 2 developed their models using deductive method. Problem solving skill inventory developed by Heppner and Petersen (1982) was used for data collection. The data collected was analyzed statistically. As part of the statistical analysis, the researcher evaluated the model records developed by students, interviews done with students and observational records of teachers. Statistically significant differences were observed in the problem-solving skills of students in both groups after the experimental study. The increase in the mean scores for problem solving skills of the experimental group 1 was higher than the increase in the mean scores of the students in the experimental group 2. System dynamics approach, which is effective in decision making process, also plays an important role in improving students’ problem-solving skills. © 2020, Ozgen Korkmaz. All rights reserved.

    An interdisciplinary nature education program for gifted primary school students and its effect on their environmental literacy
    (Ankara University, 2018) Nuhoğlu, H.; İmamoğlu, Y.
    The aim of this study is to introduce an interdisciplinary nature education program (INEP), developed for gifted students in order to create an opportunity for them to discover nature and approach environmental problems in a systematic way. Another aim is to investigate the effect of the program on environmental literacy. Participants of the study were 20 gifted primary school students. INEP took place in a botanical garden preserving the richest endemic species of Turkey. Effectiveness INEP was measured by Elementary School Environmental Literacy Instrument, consisting test of environmental knowledge (TEK), affective disposition towards environment (ADTES) and responsible environmental behavior (CREBS) scales. In addition, participating students’ performances and their views about the program were evaluated. Results of data analysis revealed significant differences in students’ environmental knowledge and affective disposition towards the environment. Student interviews and observations also support this result. In accordance with the findings, strengths and weaknesses of the program are discussed. © 2018, Ankara University. All rights reserved.
