Phet animation of a Plinko machine for teaching binomial distribution in high school

Abstract

This study evaluated the use of the PhET animation of the Plinko machine to teach the binomial distribution in a high school mathematics class, using a collaborative learning approach. Forty-one students aged 16-17 participated, divided into groups. The results show a significant improvement in the understanding of the binomial distribution, with an average increase of 25% on post-activity assessments. Most students rated the simulation positively, highlighting their ability to visualise abstract concepts. Collaborative learning facilitated active participation, especially among students with previous difficulties, who improved significantly when working in mixed groups. The findings suggest that the integration of interactive simulations and collaborative methods in mathematics teaching can be an effective strategy to improve academic performance and student motivation. Their implementation in similar educational contexts is recommended and future research is suggested to evaluate their long-term impact.
