Practical assessments demand that students not only conduct experiments safely but also understand every stage of the process. This includes selecting the range and number of values for the independent variable, determining the number of replicates, and establishing controls. Additionally, students should be competent in planning comprehensive experiments, encompassing methods of data collection and analysis.
In this blog, we will explore strategies and best practices for integrating effective laboratory work into your teaching. From fostering decision-making skills to ensuring rigorous safety standards, let’s equip our students with the practical expertise they need to excel in their assessments and beyond.
