Measures of Validity

In Chapter 30 of Lee & Owens, it is explained that you must determine how to estimate whether or not the tools for measurment are actually measuring what they are supposed to measure. Face validity is one way. This establishes that a training teaches what was meant to be taught and should be designed during the beginning phases of a project. Content validity is established through technical content review cycles during the development stage. In order to achieve face validity, have experts review course materials and validate that the course content actually is the subject to be taught. To achieve content validity, have the experts review the course materials and ensure there is unity between the objectives, course content and test items. Other types of validity include concurrent validity(similiarities bewteen two tests), construct validity(measure of scores on test in relation to job performance), test item validity(measure of relationship of individual items vs overall test) and predictive validity(measure of a test to predict the future success in a particular area). This chapter provided some great information, and I only wish we had more time to officially do this in our own projects. I would like to know how well my lesson's are actually teaching learners, and I would also like to know if their skills improve after using the training.
