Learning Effectivity Formula
|Posted By: Ely Djulia on May 21, 2006|
|My student is conducting her research to implement cooperative learning on chemistry classroom by applying experimental method. T-test is used to know whether there is significant differences of learning achievement between control group and experimental group. She also wants to know lerning effectivity by using this formula:|
mean score of exp. - mean score of control
learning effectivity = __________________________________________ x 100%
mean score of control
Is the formula above feasible in educational research?
Is anybody can give us your comment, or suggestion?
