Resumen

Σκοπός της έρευνας είναι η διερεύνηση των γνώσεων μαθητών Β’, Γ’ Γυμνασίου και Α΄ Λυκείου σχετικά με την αντιμετώπιση ανισοτικών σχέσεων και την επίλυση ανισώσεων α’ βαθμού με ένα άγνωστο. Ειδικότερα, διερευνούμε τη δυνατότητα μαθητών και μαθητριών να «μεταφράζουν» από την λεκτική διατύπωση στη μαθηματική συμβολική γλώσσα και αντίστροφα, καθώς και τη λειτουργική ικανότητα των μαθητών να χρησιμοποιούν τις απαιτούμενες, για την επίλυση ανισώσεων, αλγεβρικές πράξεις. Τα υποκείμενα της έρευνας είναι 24 μαθητές της Β Γυμνασίου, 25 μαθητές της Γ Γυμνασίου και 18 μαθητές της Α Λυκείου που καλούνται να συμπληρώσουν ένα ερωτηματολόγιο με προβλήματα ανισώσεων. Η ποσοτική και ποιοτική ανάλυση των ευρημάτων αναδεικνύει σημαντικά προβλήματα στην ικανότητα χειρισμού των παραπάνω μαθηματικών αντικειμένων.
