DQs and student responses

 

This requires a substantive, referenced written response with a minimum of 250 words per DQ. as well as reading the writings of other students and responding to at least their primary postings. Additionally, you must read the writings of all other students and respond in a substantive way to at least two of their primary postings. Your responses should contribute scholarly to the discussion by challenging a position, providing additional support, or taking the debate in a new but reasonable direction.

All DQ responses to be supported by current research, i.e. journal articles published within the last 10 years.

In your DQ responses, do not use recently published journal articles for support; using articles I provide as additional readings do not count toward this requirement. An additional twenty points will be deducted from your weekly points if sources are not properly cited. These sources should be integrated into your response, not simply placed in a sentence within the response.

DQ #1

McPhail and Stelly (2010) provided a summary of the alternative approaches for validating workplace assessments and cover the development of new validity evidence. Cizek (2012) argued the problem with validity involves incompatible uses of the term. What are the major arguments from both articles? How do the approaches toward validity differ within the two articles? Given these arguments, is it ever acceptable to use an assessment that has not been validated? As a practitioner, how will you determine the validity of an assessment?

DQ #2

Search the internet for two tests that have a high degree of established reliability and validity along with two tests that do NOT have a high degree of established reliability and validity. How did you determine whether the tests were strong or weak regarding validity and reliability? Specify the tests and where you found the information. (See the text’s Appendix for ideas on tests to search)
