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 ...

Is experimental research passé [PDF]
Advances in Health Sciences Education, 2010 In perusing the contents of this issue, I discovered that, once again, the majority of the papers are not experimental. There are several qualitative studies—of teachers’ attitudes to student feedback, reflective learning for continuing education, residents’ perceptions of outpatient teaching, and assessment expert’s view of the framework for ...

Multi-stage analysis of reliability of an example masonry construction [PDF]
Archives of Civil Engineering, 2021 The safety of the masonry structure is determined by the value of the partial factor used, which is influenced by many factors. The variability of these factors determines obtaining significant differences in the load levels of various masonry structures.
