Computational Thinking has been recognized as an essential skill to be developed in individuals of the 21st Century. Various initiatives worldwide have been proposed to establish the most effective educational strategies and resources to support the development of these skills. With the publication of the Standards for Computing in Basic Education in Brazil (Complement to the National Base Common Curricular), Computer Science is expected to be taught as a fundamental science from Early Childhood Education to High School. In this context, this study presents the results of the students’ learning and the usability evaluation of the ThinkCarpet: an interactive educational robotics artifact built using alternative materials and Arduino, with the purpose of aiding in the development of the concept of algorithms in students from Middle School. Regarding the students’ learning, an average of 93.75% of valid solutions was observed for the algorithms validated through the use of the ThinkCarpet. In contrast, only 62% of valid solutions were identified in activities outside the proposed resource. As for the results of the application of the System Usability Scale (SUS), the results show a score of 83.59, which classifies the ThinkCarpet as excellent in a realistic scenario.

计算思维已被认为是 21 世纪个人需要发展的一项基本技能。世界各地提出了各种倡议，以建立最有效的教育策略和资源来支持这些技能的发展。随着巴西基础教育计算标准（国家基础公共课程的补充）的发布，计算机科学预计将作为从幼儿教育到高中的基础科学进行教授。在此背景下，本研究展示了学生的学习结果和 ThinkCarpet 的可用性评估：ThinkCarpet 是一种使用替代材料和 Arduino 构建的交互式教育机器人工件，旨在帮助学生发展算法概念中学。在学生的学习方面，通过使用 ThinkCarpet 验证的算法平均观察到 93.75% 的有效解决方案。相比之下，只有 62% 的有效解决方案是在提议资源之外的活动中找到的。至于系统可用性量表（SUS）的应用结果，ThinkCarpet的得分为83.59，在现实场景中将ThinkCarpet评为优秀。
