Abstract
More than ever, there is an increasing need for digital experimental learning environments in chemistry. The variety of digital learning approaches provided to students range from simple videos showing experiments to highly interactive virtual laboratories. Regardless of which approach is chosen, a digital learning environment should be adapted to students’ authentic behavior in the laboratory. A special focus should be placed on their experimental skills to ensure that they are adequately prepared for the laboratory. Herein, we report how we designed a student-centered experimental environment on the basis of our observations of students’ authentic behavior and their actions in the laboratory during a titration. Our work is based on three quality factors: individuality, interactivity, and realism. Therefore, the derived digital environment mimics students’ decisions in the laboratory and allows a high degree of student-centeredness. In this article, we describe three aspects of the study: (I) how to convert students’ actions into decision trees, (II) how to set up the titration digitally, and (III) how the targeted cohort of students rated the usability.
