Effects of Teaching Strategies

A psychologist would like to examine the effects of different teaching strategies on the final performance of 6th grade students. One group is taught using material presented in class along with outdoor discovery, one group is taught using material taught in class alone, and the third group is taught using only the outdoor discovery method. At the end of the year, the psychologist interviews each student to get a measure of the student’s overall knowledge of the material.

Use an analysis of variance with α = .05 to determine whether these data indicate any significant mean differences among the treatments (teaching strategies). Remember to;
1) State the null hypothesis,
2) Show all of your calculations,
3) Make a decision about your null hypothesis,
4) Make a conclusion including an APA format summary of your findings (include a measure of effect size if necessary), and
5) Indicate what you would do next given your findings.
