This shopping service is provided to familiarize you with the nuts and bolts of multiple group post-test only randomized experimental design. There are several options provided in order to enable quick access into different aspects of this topic.
If you are not familiar with this topic, we recommend that you choose the 'best buys' button. This button will take you through a tutorial version of the theory and the common threats to validity experienced by such a design. These buttons are provided separately on the main menu as well, so that you can skip between the options.
The 'shoppers advantage' button will enable you to visit an actual post-test only randomized experimental design in Tenessee. This project is known as STAR which stands for the Student Teacher Achievement Ratio. This randomized experiment is the first and last of its kind within public education that was publically funded for four years. You will find this project to be a useful example to help you understand the dynamics of multiple group posttest-only randomized experiments.
All the buttons in the menu will eventually lead you to an interactive test based on the Project STAR research methodology. Therefore, make sure you go through the Project STAR page before taking the test. This page can be accessed through the 'shoppers advantage' button on the main menu.
All your responses will be rewarded by a reasonable level of feedback from the authors. Be sure to check this test out!
