De conclusie voor korte termijn is inderdaad correct, daar is CSWE de beste treatment. Voor de lange termijn is er geen antwoord geformuleerd. Daar is te zien, net zoals bij de vorige vraag, dat er geen enkele treatment bijdraagt tot een lange termijn leereffect, want er is geen significant verschil op te merken

Om verder te gaan op de feedback van de vorige student: Er is geen effect op lange termijn want actieve, gemotiveerde studenten zullen andere bronnen raadplegen om zo een betere testscore te behalen.
