Practices and challenges in implementing chemistry laboratory work in secondary schools: A review

Abstract

Laboratory work in secondary schools plays a paramount role in the teaching and learning process of practical activities, aiding students’ understanding of chemical concepts and experimentation. This review aimed to assess the practices and challenges of implementing chemistry laboratory work in different secondary schools in developing countries. The most recent and reputable journal publications were examined and utilized as primary sources. Fifteen studies, gathered through Google Scholar and Eric databases in the time frame from 2016 to 2024, were selected for review. Findings indicate that significant challenges, including shortages of laboratory apparatus, chemicals, and trained technicians, inadequate storage facilities, and limitations in laboratory infrastructure. These challenges hinder effective teaching and learning of chemistry, impacting students' academic achievement and attitudes towards science. Despite positive perceptions towards practical work, resource constraints and other factors limit its implementation. Curriculum expectations often differ, and practical constraints often hinder hands-on learning. Effective collaboration among stakeholders, including educational authorities, policymakers, school administrators, and teachers, is important for enhancing students' learning experiences and promoting scientific literacy.
