PITTORE O SCULTORE?

Si puo’ valorizzare una pietra scolpendola o stimandola. Ci sono abili scultori e abili periti.
Domanda: l’insegnante (rispetto ai suoi ragazzi) è più scultore o perito?

SCOPIAZZARE O BIGIARE?

Perché gli studenti copiano? Se uno pensa che siano a scuola o all’università per imparare, allora copiare non ha senso. Ma anche impedire la copiatura con ronde tra i banchi sarebbe assurdo. Se la scuola rivendica una funzione formativa dovrebbe consentire che lo studente affronti gli esami in tutta tranquillità a casa sua. Qualora invece la scuola abbia la funzione di fornire credenziali tutto cio’ che vediamo nella realtà si spiega facilmente: impedire la copiatura preserva il valore segnaletico del titolo di studio.
Perché gli studenti esultano di fronte ad un’ora buca? Se a scuola si andasse per imparare, come vorrebbe la teoria del capitale umano, dovrebbero rattristarsi. Si puo’ pensare che gli studenti siano immaturi ma all’università l’ipotesi sembra forzata; non solo, all’università potrebbero saltare l’ora di lezione poiché la frequenza non è obbligatoria. La risposta più convincente sta nel fatto che l’ora buca costringe tutti a rinunciare senza penalizzare nessuno nella corsa al pezzo di carte, l’unica cosa che conta.

SCUOLA SU, PROFESSORI GIU'

Gli studenti fanno di tutto per essere ammessi nelle scuole più prestigiose ed esigenti. Poi, quando sono dentro, fanno di tutto per avere i professori più “facili” e di manica larga. Questa modo di fare contrasta con l’assunto che si vada all’università per imparare. I datori di lavoro sanno quali sono le università più esigenti ma non sanno affatto distinguere tra professore e professore.

NON SAPERE = DIMENTICARE

Come sarebbe cambiata la vostra carriera lavorativa se prima degli esami universitari che avete a suo tempo superato brillantemente la vostra preparazione fosse stata quella che avete ora? Presumo che la vostra preparazione odierna, a distanza di anni, sia vicina allo zero e che senza il titolo di studio con cui avete affrontato i vostri colloqui lavorativi non avreste ottenuto l’impiego che avete. Ma che differenza c’è tra “non sapere” e “dimenticare”? Nessuna, in fondo. Anche “dimenticare” è una forma di ignoranza.

Di fronte alla terribile equivalenza tra “non sapere” e “dimenticare” ci si rifugia in calcio d’angolo: studiare ti migliora anche se non impari (= dimentichi) quel che studi. La psicologia educativa lavora da un secolo senza successo per capire in cosa consista questo “miglioramento”. Molto più semplice assumere che l'istruzione formale abbia poco a che fare con l'apprendere e l'insegnare.
