Learning as a dependent variable in experimental research

I am reading through a number of peer reviewed studies and noticing that there are pieces missing from each. So if you are conducting an experimental study where learning is a dependent variable you must do the the following (note these are the things I keep seeing that are missing):

  1. Pre test. This is to ensure that differences found in your study are due to the condition and not prior knowledge. Be aware that if you give the same pre test as post test, its a violation of validity but it can still be done (its better than no pre test). Thus I recommend giving a different pre test.
  2. Content Validity. Is the content you are using correct? And is the assessment measuring the objectives from the content? How do you know this? Explain this. Has an expert reviewed it? Have you piloted it?
  3. What is the reliability of the test? Please provide us this information.
  4. Provide the M, SD, and Effect.

I know all of this seems like common sense but I am seeing top tier journals publishing articles that do not contain this basic information.
