De student maakt hier duidelijk een herberekening van de originele opgave. Dit wil concreet zeggen dat de student de parameters niet heeft gewijzigd en hierdoor de originele ingevulde cijfers behoud in de berekening. De student bekomt een hierdoor een ander resultaat. Verwijzend naar het word-document waarin deze link is opgenomen, trekt deze student telkens de juiste conclusie.

een gewone herberekening van de oorspronkelijke oefening, student doet dit 3 maal correct en trekt het juist besluit namelijk dat het originele resultaat niet echt heel accuraat omdat je niet kan voortgaan op één enkele berekening.

Zij maakte meerdere reproducties van de originele opgave om daaruit de juiste conclusie te trekken.

Ik denk dat de redeneringen/feedback van de vorige studenten niet meer herhaald moeten worden.
Goede redenering.
