In 2011, Indiana lawmakers established a system to evaluate teachers using existing standardized assessments as an indicator of student learning. In this study we examined one component of Indiana's evaluation system to determine whether student knowledge of the test's consequences is predictive of test performance. Using an experimental design,…

The paper shows how the methodology for a pedagogical experiment can be improved through including the pre-research stage. If the experiment has the form of a test procedure, an improvement of methodology can be achieved using for example the methods of statistical and didactic analysis of tests which are traditionally used in other areas, i.e.…

A number of potential threats to internal validity in true experiments are discussed. Programmatic research efforts proceeding from established correlational findings to experiments employing random assignment are described and used as referents in discussions of validity considerations. The collection of observational data is recommended for use…
