Uitleg oplossing vraag 1a:
De student spreekt zichzelf tegen in zijn antwoord en is niet eenduidig. De student heeft wel ontzettend veel keer de berekening opnieuw uitgevoerd.
2008-10-19 09:56:37 [Joeri Croci] [reply] 
Naar mijn mening is vraag 1 goed opgelost. De student heeft de berekening meerdere malen uitgevoerd, merkt dat deze niet altijd dicht bij elkaar liggen. Dat de student zichzelf in vraag 1 tegenspreekt snap ik wel niet zo goed, bij mijn weten is zijn antwoord juist geformuleerd.
2008-10-20 11:11:12 [0da8ca6c46830c93169756afa1dc11e0] [reply] 
Hier sluit ik mij aan bij mijn voorganger, naar mijn mening is de oplossing correct geformuleerd.
2008-10-20 18:33:16 [Hans Van Rooy] [reply] 
Zelfde opmerking: veel pogingen, alleen de uitleg kan beter geformuleerd worden. De student begrijpt het probleem, maar maakt een fout in de uitleg.

Goede oplossing. De student heeft meerdere keren de vraag opgelost en een goed antwoord geformuleerd.
