A Systematic Review on the use of LEGO® Robotics in Education

Educational Robotics (ER) has revealed several benefits in the educational context, not only helping the teaching of disciplines, but also making possible the development of several abilities, such as teamwork, problem-solving, and creativity. Among various robotics kits, LEGO (R) Robotics has been shown one of the best results considering some evaluated criteria (modularity level, hardware, curriculum, price, etc.). Some studies analyze the teaching practices, some compare technologies, and others evaluate the kits in a pedagogical way. However, it is essential to investigate all these contexts together in order to improve the impact produced by the ER in education and to know the best teaching practices associated with the most powerful technologies. The objective of this Research Full Paper is to identify: a) environments and programming languages adopted in the LEGO (R) Robotics context, b) educational practices applied during classes based on LEGO (R) Robotics, and c) the educational levels in which robotics has been applied with positive results. To achieve these goals, we planned and carried out a systematic review of the literature. Our main findings are: a) the most widely used environment and programming language are LabVIEW along with the LEGO (R)'s block-based programming language, b) we identified LEGO (R) Robotics is used for teaching programming, interdisciplinary contents, participation in tournaments, robotics, and computational thinking, c) LEGO (R) Robotics is used with success by students of different levels, such as K12, undergraduate, and graduated. Finally, we discuss some problems and limitations related to ER and point out that there is no standardization of teaching practices or methodologies for evaluating results, indicating that more research is needed to find the best scenario regarding technologies, methods, and target audience.
