Current initiatives and laboratories concerning Educational Robotics (ER) are often not based on strong pedagogical backgrounds. Additionally, they are carried out by inadequately trained teachers, and are not evaluated properly in terms of effectiveness. Moreover, according to teachers, ER usability is often neglected. The main goal of the present article is to present a training course on ER (Edu.Ro.Co.), grounded in pedagogical insights, and to discuss the results of the course and teacher's opinion about ER in terms of: (i) teachers' attitudes and perceptions of using ER; (ii) the potential impact of ER on students' key competences for lifelong learning; and (iii) strengths and weaknesses of ER. These aspects were analysed by means of questionnaires specifically designed by the authors, and administered before and after the training course. A total of 339 teachers attended the training course and 254 completed the questionnaires. The article describes the methodology utilised in the realisation of the course and analyses the questionnaire's results. In particular, the number of teachers that considered themselves prepared to apply ER significantly improved after the training course. ER is considered by teachers an important tool for the improvement of students' motivation, planning skills, team working, problem solving and creativity development. Finally, the results from questionnaires indicate that teachers consider ER, a method that improves team-working abilities and motivation in the students. In contrast, the main disadvantage is the cost of the robotic kits. Based on these results, new directions for future research in ER are discussed.
Studies have shown that educational robotics (ER) may impact student learning, especially in relation to STEM (science, technology, engineering, and mathematics) areas.In the STEM framework, particularly for younger children, the "E" and the "T" are considered to be missing letters, because few studies have concentrated on teaching and evaluating technology and engineering through ER activities. This study aimed to develop and test the efficacy of an ER protocol to teach robotics in a sample of 389 students, hypothesizing that girls would be as successful as boys. A Robotics Questionnaire assessing the basics of robotics was developed for this study. A Wilcoxon nonparametric test was performed in order to evaluate improvements (p < 0.05). A Mann-Whitney nonparametric test was performed in order to test the presence of gender differences (p < 0.05). Data indicated significant improvements for all the age ranges considered. No gender differences were found. In order to evaluate the efficacy of a didactic intervention utilizing ER, it is important to assess the impact on children's technological and engineering (robotics, in particular) knowledge.
Catching a flying ball is a difficult task that requires sensory systems to calculate the precise trajectory of the ball to predict its movement, and the motor systems to drive the hand in the right place at the right time. In this paper we have analyzed the human performance in an intercepting task performed in an immersive virtual environment and the possible improvement of the performance by adding some feedback. Virtual balls were launched from a distance of 11 m with 12 trajectories. The volunteers was equipped only with shutter glasses and one maker on backhand to avoid any constriction of natural movements. We ran the experiment in a natural scene, either without feedback or with acoustic feedback to report a corrects intercept. Analysis of performance shows a significant increment of successful trials in feedback condition. Experiment results are better with respect to similar experiment described in literature, but performances are still lower to results in real world.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
