Hier ist ein Fass übergelaufen. Zu Recht!

„This is another useless comparative study between online and face-to-face teaching. This study looked at 312 undergraduate students in one microeconomics course in one unnamed state university and found that male, Hispanic and low achieving students did worse online than in face-to-face classes. From this the NBER had the cheek to conclude that online learning is not all that it’s cracked up to be.
…
And will someone please tell researchers that they have to look at other variables besides the mode of delivery – such as the quality of the teaching – when making comparisons? Correlation is not the same as causality.“
