Reasons for validating scientific reasoning datingand love net
In yet other terms, did we operationalize well the ideas of the cause and the effect?When our research is over, we would like to be able to conclude that we did a credible job of operationalizing our constructs -- we can assess the construct validity of this conclusion.Assume that we took these two constructs, the cause construct (the WWW site) and the effect (understanding), and operationalized them -- turned them into realities by constructing the WWW site and a measure of knowledge of the course material.Here are the four validity types and the question each addresses: In the context of the example we're considering, the question might be worded: in this study, is there a relationship between the WWW site and knowledge of course material?When we want to make a claim that our program or treatment caused the outcomes in our study, we can consider the internal validity of our causal claim.In simpler terms, did we implement the program we intended to implement and did we measure the outcome we wanted to measure?
Imagine that we wish to examine whether use of a World Wide Web (WWW) Virtual Classroom improves student understanding of course material.
We might conclude that there is a positive relationship. We can assess the conclusion validity of each of these conclusions or inferences. Both could, for example, be caused by the same factor.
For instance, it may be that wealthier students who have greater resources would be more likely to use have access to a WWW site and would excel on objective tests.
Technically, we should say that a measure leads to valid conclusions or that a sample enables valid inferences, and so on.
It is a proposition, inference or conclusion that can 'have' validity.
