Supporting students’ inquiry in accurate precipitation titration conditions with a virtual laboratory tool as learning scaffold

Abstract

This work uses a virtual laboratory (VL) as a learning scaffold for students to explore the conditions for accurate titration. A simulation program for precipitation titration and a simulation-based exploration exercise were developed. The exercise consists of three questions/tasks related to conditions for accurate titration, in which students independently design solutions, conduct virtual experiments, analyze the results, and draw conclusions based on the guided questions. After using the program, 22 chemistry education students who do not often use the app found the program to be easy to use, practical, and effective, and achieved a scoring rate of 79.4% in the exercise.
