An educational psychologist designs a demanding but fair spelling test that can be administered to grade school children. The te

st is found to be valid and reliable. A researcher selects the test to help evaluate a “cognitive” approach to teaching spelling. A 5th grade class is tested prior to being taught the new method at the beginning of the school year and then again after the new method is taught at the end of the year. The children show improvement on their spelling scores from the first to the second test administration, suggesting that the program was effective in helping children to learn to spell. What is a threat to the internal validity of the study?

The answer is: Testing

One thing that can question the internal validity of the case above is the difficulty between the first and the second test since the psychologists never really mention it.

If, let's say that the questions on the second tests are exactly the same as the first tests or have lower difficulties compared to the first one, the better performance given by the student is not necessarily influenced by the teaching method.

Fittoniya [83]

Answer: C. Making the initial determination that information requires protection against unauthorized disclosure in the interest of national security

Explanation: Derivative classification means the incorporating, paraphrasing, restating, or generating in new form information that is already classified, and marking the newly developed material consistent with the classification markings that apply to the source information. While working with classified information, individuals sometimes generate or create new documents and materials based upon that classified information. These individuals who reproduce, extract, or summarize

classified information, or who apply classification markings derived from

source material or as directed by a classification guide, need not possess

original classification authority. The newly created documents must be classified based upon the classification level of the information from which the new document was developed.
