Geneticus Investigatio: A Classroom-Based Technology-Enhanced Learning Environment for Problem-Solving Process Skills in Genetics

Abstract

Solving problems in science domains requires learners to integrate concepts across topics, along with problem-solving and inquiry process skills. The complexity of these concepts and skills becomes manifold at the tertiary undergraduate level, and are known to be challenging for learners. To support learners in this process, we have designed and developed Geneticus Investigatio (GI), a technology-enhanced learning environment for semi-structured problems in the context of Mendelian genetics. GI facilitates the integration of concepts and problem-solving process skills, through inquiry-based learning activities interspersed with evaluative question prompts and reflective activities. GI is developed using Google site s and H5P as a web-based learning environment to provide easy access to learners and to enable teachers to adapt the learning activities to different topics. In this paper, we present the theoretical basis and design of GI. We report a quasi-experimental classroom study (N=63) in which we investigated learning of problem-solving skills and perceptions of usability and usefulness of GI. The results indicate higher learning gains of problem-solving process skills with GI, and learner perceptions that certain activities in GI are helpful for learning concepts and process skills.
