Experimental and Quasi-Experimental Research in CSCL
, 2021 (Quasi-)experimental designs play an important role in CSCL research. By actively manipulating one or several independent variables while keeping other influencing factors constant and through the use of randomization, they allow to determine the causal effects of such independent variables on one or more dependent variable(s) that may be of interest ...
