The results of the measurement will play a critical role in determining the effectiveness of the parenting classes in improving the parenting skills of the learners.
Moreover, the quasi-experimental design does not involve random selection of participants. Therefore, the design will not have a control group, and this means that the effectiveness of the learning program will only be evaluated based on the results obtained from the pretests and the posttests (Campbell & Stanley, 2015). More so, this approach will be pivotal in minimizing the level of attrition in the program. Consequently, the results of the study will be compared with the desired learning outcomes.
Moving on, the expected results will be internally valid because they will indicate the extent to which the program has improved the parenting skills of the learners.
