The research method employed is quasi-experimental, utilizing a non-equivalent pretest-post-test control group design to gather comprehensive insights. Data collection involves the strategic use of pre-tests, post-tests, and observation sheets to capture nuanced aspects of the learning process. The findings of the research indicate that the application of the discovery learning model, complemented by scaffolding-based Student Worksheets in stoichiometry learning, has a transformative impact. It is observed that students exposed to this method exhibit heightened engagement, reflected in their learning activities categorized as 'very good.' The calculated learning effectiveness, quantified by a substantial n-gain value of 0.71, attests to the high efficacy of this pedagogical approach, placing it in the 'high' category. These results carry significant implications for educational practitioners and curriculum developers. Educators can leverage the discovery learning model augmented with scaffolding-based Student Worksheets to enhance student participation and comprehension in stoichiometry. The demonstrated effectiveness of this approach suggests its potential integration into chemistry education methodologies, promising improved learning outcomes.</p> Maysara Wa Ode Aulia Wahyuni Muh Alim Marhadi Dahlan Aceng Haetami Esnawi Copyright (c) 2024 2024-02-19 2024-02-19 16 1 1 7 10.55217/101.v16i1.744
