The analysis and answer to the six research questions is presented in this section. For all the corresponding research hypotheses, a reliability analysis is conducted for the scale variables used as dependent variables.
.
Research Hypothesis #1
The following needs to be tested:
No significant difference should be found in overall learning effectiveness between technology-based versus technology-enhanced versus traditional face-to-face courses.
For this research question, the dependent variable (DV) is Learning Effectiveness (from the Learning Objective Instrument). Table 1 below shows the results of a reliability analysis conducted to assess the validity the DV.
| Table 1: Reliability Statistics | |
| Cronbach's Alpha | N of Items |
| .945 | 67 |
The constructed dependent variable Learning Effectiveness is validly constructed, since the value of Cronbach’s Alpha is 0.945, which exceeds the commonly agreed threshold of 0.7. Once it has been assessed the DV is validly constructed, an ANOVA needs to be conducted.
