    Get PDF
    Raspberry Pi is a powerful and affordable small computer. It was produced with an aim in education to help young adult learn about computer and programming language. Hence, it consists of high functional features and is sold at low cost for easy access to everybody. Moreover, there are many supports available for Raspberry Pi in both technical and commercial field making it appealing for running various kinds of application. In this thesis, Raspberry Pi computer is studied and evaluated for its features and capability using Matlab software as a code porting tool due to a free availability of the support package. The implementation is done with examples of signal and image processing based on problem from relevant courses in university level as well as real world applications from Simulink Computer Vision toolbox. The model is constructed using Simulink blocks and Matlab scripts. The input is provided in two ways; one as a parameter added through the software and the other is fed directly from a peripheral device. With an aim to provide the use of Raspberry Pi computer in practical courses, a limitation of model compilation time is taken into account for the evaluation. The results from examples show that time taken to generate the code is slower if the model comprises many Simulink blocks or contains Matlab scripts. The larger size and software input parameter also causes the delay compilation. However, these factors fall into an acceptable range. Hence, Raspberry Pi can be used with Matlab as a learning tool for hands-on experience for students. The possibility of the future work would include the use of graphic processor in Matlab and Simulink application. The research would involve determining Matlab code generation method used as a compiler for a graphic processor modified code

    Το Raspberry pi είναι ένας υπολογιστής μικρού μεγέθους και χαμηλού κόστους, ο οποίος χρησιμοποιείται στο πλαίσιο της εκπαίδευσης. Η εν λόγω τεχνολογική καινοτομία παρέχει τη δυνατότητα εξοπλισμού ολόκληρων τάξεων λόγω του χαμηλού κόστους του, την εύκολη μεταφορά του λόγω του μικρού μεγέθους και πλήθος δυνατοτήτων στον μαθητή κατά τη διδασκαλία, όπως αλληλεπίδραση με γλώσσες προγραμματισμού και παρέμβαση στο λογισμικό. Πολλές έρευνες έχουν εντοπίσει τα πλεονεκτήματα της χρήσης του στην εκπαίδευση, όπως παρακίνηση των μαθητών, διατήρηση του ενδιαφέροντος τους, καλύτερα μαθησιακά αποτελέσματα και υψηλότερη παραγωγικότητα και αποτελεσματικότητα του εκπαιδευτικού. Καθώς, αντίθετα με το εξωτερικό, στην Ελλάδα δεν έχει χρησιμοποιηθεί η εν λόγω τεχνολογία, πραγματοποιήθηκε πρωτογενής ποσοτική έρευνα με σκοπό τη διερεύνηση των στάσεων και των πεποιθήσεων των εκπαιδευτικών πρωτοβάθμιας εκπαίδευσης της Ελλάδας σχετικά με τη χρήση του Raspberry pi στην εκπαίδευση. Διαμοιράστηκε δομημένο ερωτηματολόγιο, το οποίο δημιουργήθηκε με βάση 1) τη Θεωρία Προσχεδιασμένης Συμπεριφοράς, η οποία αποτελεί μια προσέγγιση της κοινωνικής ψυχολογίας για την πρόβλεψη της ορθολογικής συμπεριφοράς των ανθρώπων σχετικά με τη λήψη αποφάσεων και 2) το Μοντέλο Αποδοχής της Τεχνολογίας, το οποίο χρησιμοποιείται για να προβλέψει αν μια νέα τεχνολογία θα υιοθετηθεί από άτομα, ομάδες ή οργανισμούς. Το δείγμα αποτέλεσαν 105 εκπαιδευτικοί πρωτοβάθμιας εκπαίδευσης που εργάζονται σε σχολεία του νομού Αττικής. Τα αποτελέσματα έδειξαν πως το δείγμα είναι θετικό απέναντι στη χρήση του Raspberry pi, πιστεύει ότι είναι χρήσιμο και εύκολο στη χρήση, ωστόσο το οικονομικό κόστος είναι ένα στοιχείο που δυσκολεύει τη χρήση του. Επίσης, οι συμμετέχοντες προτίθενται να το χρησιμοποιήσουν μελλοντικά στο πλαίσιο της διδασκαλίας τους. Οι μεγαλύτερης ηλικίας συμμετέχοντες είναι πιο αρνητικοί απέναντι στο Raspberry pi από ότι οι νεότεροι. Τέλος, οι άνδρες έχουν περισσότερους ενδοιασμούς από τις γυναίκες σχετικά με τη δυνατότητα αξιοποίησης του από όλες τις ειδικότητες εκπαιδευτικών και την ευκολία μετακίνησης του από αίθουσα σε αίθουσα.The Raspberry pi is a small, low-cost computer used in education. This technological innovation provides the ability to equip entire classrooms due to its low cost, easy portability due to its small size and many possibilities for the student during teaching, such as interaction with programming languages and software intervention. Many studies have identified the benefits of using it in education, such as motivating students, keeping them interested, better learning outcomes, and higher teacher productivity and efficiency. As, unlike abroad, this technology has not been used in Greece, a primary quantitative survey was conducted to investigate the attitudes and beliefs of Greek primary school teachers regarding the use of Raspberry pi in education. A structured questionnaire was distributed, based on 1) the Theory of Pre-planned Behavior, which is a social psychology approach to predicting people's rational decision-making behavior, and 2) the Technology Acceptance Model, which is used for predict whether a new technology will be adopted by individuals, groups or organizations. The sample consisted of 105 primary school teachers working in schools in the prefecture of Attica. The results showed that the sample is positive for the use of Raspberry pi, he believes that it is useful and easy to use, however the financial cost makes it difficult to provide. Also, the participants intend to use it in their teaching in the future. Older participants are more negative about Raspberry pi than younger ones. Finally, men have more doubts than women about the possibility of using it by all specialties of teachers and the ease of moving it between classrooms
