Abstract


This study developed and validated a Virtual Laboratory Package (VLP) for effective teaching and learning of Biology practicals in Secondary Schools in Nigeria. A Research and Development (R & D) design was used and the population entails all the secondary school Biology teachers and students in Nigeria. 12 Biology teachers and 216 students participated in the study. The participants were selected through a multistage sampling technique across the six geopolitical zones in the country. A comprehensive desk review of the Biology curriculum was used in screening the laboratory activities included in the VLP model and a round table discussion with Biology teachers was carried out for harmonizing the activities used in the VLP model. Python programming language (Django framework) was used for the logic while Hypertext Mark-up Language (HTML) and Cascading Style Sheet (CSS) were used for the user interface. Data was collected through three instruments namely; VLP Content Validation Questionnaire (VLCVQ), VLP Functionality Questionnaire (VLPFQ) and VLP Usability Questionnaire (VLUQ). The data were analysed through charts, percentages, mean and standard deviation. The VLP was developed and found functional, suitable and user-friendly for effective teaching of Biology practicals.
