The role of practical laboratory work in stimulating students' interest in natural sciences

This study examines the role of practical laboratory work in stimulating students' motivation and perceived learning effectiveness in natural science subjects in lower secondary schools in the Republic of Kosovo. Using quantitative research design, data were collected through structured questionnaires administered to 168 science teachers and 183 seventh grade students across 24 public lower secondary schools. The study focuses on the implementation of laboratory work, the availability and quality of laboratory equipment, and students' perceptions of learning in Biology, Chemistry, and Physics, within the framework of the national curriculum. Descriptive statistics and chi-square tests were used to examine associations between laboratory practices, instructional conditions, and student motivation. The findings show that participation in laboratory activities is positively associated with higher levels of student motivation and perceived learning effectiveness, with statistically significant differences across subjects. Chemistry demonstrates the strongest perceived benefits when laboratory conditions are adequate, whereas limitations in equipment and infrastructure constrain effective implementation in Physics and Biology. Overall, the results underline the pedagogical value of practical laboratory work while highlighting structural inequalities in access to laboratory resources. The study offers evidence-based recommendations for curriculum implementation, teacher professional development, and institutional investment to support more equitable laboratory-based science education in lower secondary schools.
