Abstract
Educational robotics provides an excellent opportunity for orchestrating open-ended learning activity sequences in inquiry learning that involve a trajectory with questioning and exploration instead of the more close-ended trajectory with hypotheses and experimentation. In the present study, we developed and implemented an educational intervention in real classroom contexts, which intended to integrate inquiry-based learning and educational robotics. We planned for multiple iterations, where students were engaged in subsequent cycles of design, programming, testing, and revision. To monitor and evaluate student performance, we assessed the quality of learning products delivered by students. Our objective was to examine if student performance improved within and across iterations. Participants were 46 Cypriot primary school students, who worked in groups of two (5 groups) or three (12 groups) to design routes of a robotic vehicle in a hypothetical neighborhood, translate these instructions into block-based programming creating flow diagrams, test the movement and behavior of the GINOBOT and improve their flow diagrams so that the observed movement and behavior match their instructions. The same cycle was repeated in four iterations with increasing programming complexity. In contrast to previous research, which has documented a decreasing trend in achievement when young children were engaged in multiple lessons of block-based programming of increasing difficulty, our results indicate that students progressed within each iteration as well as from one iteration to the next. Our constructionist approach can be exploited for assessing student performance in open-ended learning settings with few participants, where control groups cannot be easily compared to experimental groups, and where pre-post tests would most probably fail to grasp the richness of student actions and paths.
