20.500.12556/RUL-166733 Introduction of hydrosphere environmental problems in lower secondary school chemistry lessons The 2030 Agenda for Sustainable Development focuses on ensuring a healthy environment for present and future generations by avoiding risks associated with consumption, exploitation of natural resources and pollution. Maintaining an environmentally aware society to address hydrosphere environmental problems requires environmental literacy, which should be continuously improved through environmental education. The study aimed to evaluate the effectiveness of integrating hydrosphere environmental problems into chemistry lessons through an online workshop, comparing students’ achievements and their situational and individual interest before and after participating in the workshop. Altogether, 145 students from seven Slovenian lower secondary schools participated in the study. Three-tier achievement tests assessed students’ knowledge about hydrosphere environmental problems before and after the workshop, while 15-item and 10-item questionnaires measured individual and situational interest. Results showed that 42.1% of students achieved more than half of the points on the preliminary achievement test, while following the workshop, 61.5% of students achieved better results on the achievement post-test. Students struggled to understand the chemical structures of pollutants and their effects on the hydrosphere. No significant differences in results on the post-test and delayed achievement test were identified, but high individual and situational interest positively influenced students’ results on all achievement tests. hydrosphere environmental problems lower secondary school chemistry education interest na učenca osredotočen pristop učenje na prostem kompetence pripravništvo samoocena hidrosfera srednješolsko izobraževanje true false true Angleški jezik Slovenski jezik Članek v reviji 2025-01-23 12:18:47 2025-01-23 12:18:49 2025-01-24 04:05:29 0000-00-00 00:00:00 2025 0 0 27 str. iss. 1, art. 111 Vol. 15 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 373.5:502.51 2227-7102 10.3390/educsci15010111 223459587 RAZ_Klemen_Taja_2025.pdf RAZ_Klemen_Taja_2025.pdf 1 96121EDBDC420DBD1AB8A4F508D51013 24a9aecf00facdcb96d6065174365a6cd3fa9aa557a3ba43a273abcd0086e08d f1c742ed-d97b-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=198559 https://www.mdpi.com/2227-7102/15/1/111 1 077a3df0-d97b-11ef-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=198558 Pedagoška fakulteta 0 0 0
