Abstract

This study investigated learner and teacher perspectives of chemistry textbooks, alongside a comparative analysis of textbook variations and the presentation of qualitative analysis concepts. A mixed-methods approach was employed, surveying 466 learners and 33 teachers, and evaluating three widely used chemistry textbooks in Ghana senior high schools. The findings revealed learners' positive perspectives of textbooks, but highlighted the need for enhanced visual and digital support. Teachers prioritized curriculum alignment and guidance, yet recognized gaps in concept representation. Textbook analysis exposed varying levels of comprehensiveness, presentation styles, and omissions. The study highlights the importance of considering learner and teacher perspectives, alongside textbook variations, to inform chemistry education. Recommendations include developing learner-centered textbooks, providing teacher professional development, and ensuring curriculum alignment and comprehensive concept representation. This research contributes to the ongoing effort to improve chemistry education, informing teachers, policymakers, and textbook developers. By addressing identified gaps, teachers can foster a deeper understanding of qualitative analysis concepts and promote effective learning outcomes.

Abstract

Chemical change is a fundamental yet challenging concept in Chemistry. This quasi-experimental study used a pretest-posttest non-equivalent groups design to investigate the impact of inquiry-based learning on learners' conceptual understanding of chemical change. Seventy-three learners received inquiry-based instruction, while sixty-nine learners received traditional teaching methods. The results showed significant improvement in the experimental group's conceptual understanding, with medium to high N-Gain scores indicating notable enhancement.  In contrast, the control group demonstrated minimal improvements, with low N-Gain scores indicating limited enhancement. The findings suggest that inquiry-based learning effectively promotes learners' conceptual understanding of chemical change. This approach encourages active engagement with scientific concepts, develops critical thinking skills, and fosters a deeper understanding of complex phenomena. The study's results have implications for science education, highlighting the importance of incorporating inquiry-based learning into the science curriculum. The findings contribute to existing research on inquiry-based learning, underscoring its potential to enhance learners' conceptual understanding and promote excellence in science education.
