Why is the Solomon 4 group design considered the most robust design?
Rationale 2: The Solomon four-group design is considered the most prestigious design because it minimizes threats to internal and external validity and controls the reactive effect of the pretest. Experimental research is conducted to establish a cause-and-effect relationship.
How does the Solomon four-group design show the testing effect?
Example. In a teaching experiment the Solomon design shows that testing before and without treatment have similar results, whilst results after teaching are significantly improved. This indicates that the treatment is effective and not subject to priming or learning effects.
What four groups are needed in the Solomon 4 group design?
The four groups have four different experiences: Pre-test, treatment, post-test. Pre-test, no treatment, post-test. Treatment, post-test.
What is the major threat to validity of Solomon four-group design?
When conducting a study with a pre-test/post-test design (i.e., a repeated-measures study), one of the major threats to validity that you will face is the threat of testing effects.
What does a Solomon four-group design assess quizlet?
Solomon four group design: An experimental design that is used to evaluate the effect of pretesting.
Which of the following statements is true of the Solomon four-group design?
Which of the following statements is true of Solomon four-group evaluation design? It combines both pretest/post-test comparison group and post-test-only control group design. Formative evaluation mainly involves collecting quantitative data, whereas summative evaluation involves collecting qualitative data.
What is the purpose of the Solomon four-group design quizlet?
Why does the Solomon four-group design consist of an identical pretest-posttest control group design? to protect against the threats of to internal validity.
Which of the following statements is true about the Solomon four-group design?
What are the advantages of Solomon four-group design?
Implications: The benefits of using the Solomon Four group design far out- weigh the obstacles. This rigorous design provides the researcher confidence in the significance of study results since it guards against both threats to internal and external validity.
