In a pre/post quasi-experimental study assessing the impact of a specific curriculum on critical thinking, the authors employed a critical thinking curriculum in two sections of a U.S. foreign policy class. The authors found that the interactive and scaffolded critical thinking curriculum yielded statistically significant critical thinking increases for students scoring below average on the pretest. Within a discussion of the overall need for strengthening critical thinking in higher education, the authors demonstrate that the study's findings support the developmental process of acquiring critical thinking, and illustrate that early jumps in critical thinking can be achieved within one semester. Additionally, the results point to the need for more long-term approaches to assess larger increases for those scoring above average.
