Subclaims¶

q2 i? Moderated regressions show significant interactions between user type and predictors for perceived usefulness and attitude, but not for behavioral intention or frequency of use. → Pynoo 2012

Evidence¶

Pynoo 2012¶

Pynoo, B., Tondeur, J., Van Braak, J., Duyck, W., Sijnave, B. & Duyck, P. (2012). Teachers' acceptance and use of an educational portal. Computers & Education, 58(4), 1308-1317. https://doi.org/10.1016/j.compedu.2011.12.026

q2 · i? · associational · r2

Pairwise moderated linear regressions tested whether path coefficients differed between user types. The results report that "the portal’s usefulness is more important for light users in their attitude formation (β -.09, p=.01)" compared to medium users.

"Comparing the light and medium users, we find that the portal’s usefulness is more important for light users in their attitude formation (β -.09, p=.01). Comparing the light and heavy users, we see that light users draw more on their social environment when evaluating the usefulness of the portal (β -.10, p=.01)."

Discussion¶

Related Claims¶

• Attitude is the strongest predictor of behavioral intention for new users, while perceived usefulness is strongest for light, medium and heavy users — reports the opposite
• Portal users can be classified into four types (new, light, medium, heavy) based on observed usage parameters — a broader claim this one bears on
