The effects of an experimental research methods chapter on introductory psychology students' ability to evaluate scientific claims

The lack of the teaching of scientific critical thinking is seen as a major problem in the American educational system by many current educators, theorists, and researchers. Using Introductory Psychology students as subjects, the present study attempted to improve these skills by teaching students using new research method materials as part of classroom instruction. The students were measured with a test developed for the study. The new materials were found to improve students' scientific critical thinking ability over students in courses not using the new materials. These materials can be helpful in improving students' ability to evaluate scientific claims presented in the media.
