This research study explored robotics as the catalyst for computational thinking (CT) by sixth-grade students as they are engaged in a science lesson. The interactions, understandings, and applications are discussed, along with the participants' connections and implementations of CT concepts (decomposition, abstraction, pattern recognition, and algorithmic design) utilized within the LEGO® Mindstorms® EV3 robotics unit. The study presents evidence and classroom examples that demonstrate how robotics and problem-based learning are connected to CT in the classroom. The results indicate that the unit activity based on a real-world problem led to proficient and real CT concept experiences of collaboration, communication, critical thinking, creativity, and teamwork ranging throughout the hands-on activities.
