Dear All,
I went through one of the suggested papers about self-efficacy (Self-efficacy and mental models in learning to program, Ramalingam et al, 2004). Unfortunately I'm at present totally unable to understand the final results (path analysis of the model):

post Self-Efficacy (R2 = .44) ==23*==> Performance - Grade (R2 = .30)
Mental Model (R2 = .05) ==.40*==> Performance - Grade (R2 = .30)

The paper says that "both what student know, as represented by their internal mental model, and what they believe about themselves, as represented by their self-efficacy, affect their performance in the course."

Is there a naive way of rephrasing the 23* and .40* weights on the arrows from "post Self-Efficacy" to "Performance - Grade" and from "Mental Model" to "Performance - Grade"? I mean, in terms of percentages, meaningfulness or other.

Thanks in advance for all the help you keep giving me
