    Implementing STEAM Activities with Biology Teachers in the Context of Ecology
    (Univ Granada, Fac Ciencias Educacion, 2025) Aydin, Ganime; Tezcan, Gamze; Yalcin, Fehime Sevil
    This study investigates the impact of ecology-based STEAM (Science, Technology, Engineering, Art, and Mathematics) activities on biology teachers' ecological citizenship, STEAM awareness, and attitudes toward art education. Designed as a convergent parallel mixed-methods study, it involved 26 inservice biology teachers from diverse regions in T & uuml;rkiye. Quantitative data were collected using three validated instruments: the Ecological Citizenship Scale, the STEM Awareness Scale for Secondary School Teachers, and the Attitude Toward Art Education Scale, applied as pre- and post-tests. Qualitative data was obtained through teachers' daily reflections, focus group interviews, and lesson plans developed during the training.The results showed significant improvements in teachers' ecological citizenship, STEM awareness, and attitudes toward art education. Teachers appreciated the interdisciplinary nature and classroom applicability of the 26 STEAM activities conducted over six days. While participants expressed high motivation to integrate STEAM practices, some lesson plans revealed insufficient interdisciplinary alignment, particularly in incorporating engineering, mathematics, and technology components. The findings highlight the potential of STEAM-based professional development to support both environmental awareness and pedagogical growth. However, the study also underscores the need for ongoing support in curriculum literacy and integrated instructional design to ensure the effective adoption of STEAM approaches in science education.

    Stimulating growth parameters by magnetic field in irradiated with gamma radiation soybean varieties
    (Taylor & Francis Ltd, 2025) Ozdinc, Name; Yalcin, Fehime Sevil
    All biological systems are affected by radiation and magnetic fields (MFs). This study investigated the effects of gamma radiation and magnetic field treatments, both separately and together, on the seedling percentage, length, and chlorophyll content in the M1(first generation of plants) generation of Defiance, General, and Iraquois soybean cultivars. A magnetic field (MF) with a flux density of 3.8-4.8 mT was applied to the seeds of three soybean cultivars at a speed of 1 m/s for 2.2 s (1 time MF), 6.6 s (3 times MF), and 19.8 s (9 times MF). Additionally, 200 and 250 Gy gamma radiation were applied combined with a magnetic field (200, 250 Gy + MF). The treated seeds were grown in a greenhouse under controlled conditions, and each treatment was repeated three times using a randomised block design. On the 14th day, the seedling emergence percentage, seedling height, and chlorophyll content of seedlings were determined. ANOVA, Tukey, and Kruskal-Wallis tests were used for statistical analysis of the obtained data. The results showed that magnetic fields positively affected germination in Defiance and General; radiation generally reduced growth, but the combination of treatments affected seedling growth and chlorophyll content, with effects varying depending on dose and variety.
