One issue facing teachers who implement model-based instruction within the school system is the tight curricular schedule. The 'lesson objective tension' calls for investigations to address instructional issues such as how to organise modelling-based instruction at the curriculum level which is across multiple units. We investigated the effect of…

Research has revealed that learning, especially in the field of science, is strongly affected by various factors. These factors include students' attitudes towards the subject matter, and the manner in which the subject is taught. Given their close linkage to students' achievement, attitudes are relevant component in science learning. However,…

As educational settings increasingly integrate innovative technologies into teaching methodologies, it becomes crucial to understand how teachers, especially those in rural schools, develop and apply these integrative competencies. Neglecting this endeavour risks leading to the abandonment or underutilisation of these technologies once they are…

Laboratory courses can help students learn in a meaningful way. In the past, students encountered difficulties in chemistry laboratory courses due to limited access to equipment and space for practicing experimental operations. In recent years, virtual laboratories have allowed students to repeatedly practice in order to achieve their experimental…

This study investigated the learning dimensions that occur in physical and virtual inquiry-based lab investigations, in first-year secondary chemistry classes. This study took place over a 2 year period and utilized an experimental crossover design which consisted of two separate trials of laboratory investigation. Assessment data and attitudinal…

This paper reports findings from a project implementing the VL (virtual labs) site featuring flash-based animations developed at Stanford University. The main conclusion in this paper stresses the need to design for flexibility and adaptability of interactive media to better suit the specific situation teachers encounter in their everyday work, in…
