WERNER COMPLEX: Game-Based Learning in the Classroom for the Construction and Nomenclature of the Coordination Compounds

Abstract

WERNER COMPLEX is a didactic tool designed to reinforce the understanding of nomenclature and the construction of coordination complex compounds according to the IUPAC rules. In this game, students take on the role of inorganic chemists working on the synthesis of coordination complexes in a shared laboratory setting. The primary objective is to accumulate points by synthesizing coordination complexes using a variety of metals and ligands. Initial results of this card game revealed that only 6.9% of students passed a test after conventional instruction, with a mean grade of 1.7 (3.0 is the minimum for approval). However, after the introduction of WERNER COMPLEX, the passing rate increased significantly to 48.3%, and the mean grade improved to 2.6. A paired t test analysis confirmed this improvement in learning outcomes (t(56) = −3.496, p = 0.001) for its design and the possibility to study in teams. The game encourages pattern recognition rather than rote memorization, aiming to enhance motivation, retention, and cognitive engagement. These findings suggest that game-based learning is an effective approach in chemistry education.
