Online education presents challenges in maintaining engagement, interactivity, and effective teamwork. This study is based on a teaching experience in the Applied Statistics for Engineering course at the Polytechnical University of Valencia, where an innovative approach to online problem-solving seminars has been implemented using Microsoft Teams. The current methodology integrates project-based learning and debates to offer a dynamic, flexible, and updated learning experience.

Students worked in permanent groups or "bubbles" throughout the course. The latest innovation introduced team-based competition to enhance learning. Due to technical limitations, these seminars were conducted through Microsoft Teams without predefined room assignments, maintaining competitiveness and engagement.

This study compares this approach with conventional teaching, evaluating student commitment, participation, and learning quality. It analyzes how the combination of dynamism, interaction, and participation enhances problem-solving skills and collaborative learning.
