This article is focused onvarious issues involved in comparing related groups and measuring change with pretest and posttest data. Different pretest-posttest designs are discussed in a manner that can help researchers to select suitable test in order to maintain internal and external validity ...
While pretests help educators tailor curriculum on the front-end, posttests help educators see where changes need to be made to improve students’ ability to comprehend and retain the material in the future. And comparing pre- and posttest scores lets educators drill down into specific areas of...
The workshops incorporated experiential learning and self-reflection (Loucks-Horsley et al. 1998). Educators demonstrated significant increases in knowledge as revealed by pretest and posttest scores on the same test that was used during the field-testing of the module, Bioinformatics and the Human ...
摘要: Comments on the comparative analytic methods used in pretest-posttest research designs. Analysis of covariance on the posttest score using pretest as covariate; Effects of regression on mean score; Hypothesis on pretest-posttest experiments....

Discusses two approaches to data analysis in pretest-posttest research designs in which researcher has not formed groups based on pretest or used pretest information in assigning participants to groups, thus ruling out two-way analysis of variance. Describes use of repeated-measures analysis of varian...

In previous sets of notes in this series we analyzed a pretest-posttest, two-group, quasi-experimental design using blocking, matching, and analysis of covariance procedures. Those procedures were used to analyze the differences in posttest scores after any pretestOverview, I...
