The use of LEGO mindstorms in elementary schools

Abstract

Popular interest in robotics has increased significantly over the last years. It has been claimed that robotics can provide new benefits to the learning process at all levels of education. The main ideas of the present study adhered to the constructionist theory, according to which the learning process is not only transmitted from teacher to pupil, but rather constructed in the mind of the pupil in the form of active learning. The purpose of the present study was to implement a robotic toy (Lego Mindstorms NXT <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">TM</sup> ) in a Greek primary school, in order to teach twelve year-old children some of the basic concepts of geometry. The main hypothesis of the present study was that children who used the Lego Mindstorms NXT platform would score higher on an evaluation questionnaire than children who formed the control group. Descriptive statistical analysis was performed in order to evaluate the correct answers of the questionnaires. Statistical analysis revealed that children who participated in the experimental group performed better in the 21 items of the questionnaire. Moreover, they mentioned that the geometry course became more interesting and drew their attention in comparison to the courses that were taught through the standard teaching process. It is apparent that the present study follows the line of inquiries that supports that robotics can make a significant impact to education. Robots can be a tool that can enhance the skills of children.
