We studied rookie teachers working in really tough neighborhoods, asking which teachers are still going to be here in teaching by the end of the school year, and of those, who will be the most effective at improving learning outcomes for their students?
Vam estudiar professors novells que treballaven a barris molt durs,  i ens preguntàrem quins seguirien ensenyant allà encara a final de curs i quins d'aquests tindrien millors resultats respecte al que aprenien els seus alumnes.
