Objective : The present paper examines improvement of critical thinking (CT)among baccalaureate nursing students using an educational intervention that emphasizes student independence. During the intervention, students were expected to be purposeful, systematic, and analytic, and able to draw inference.
Methods : In the educational intervention, which lasted 6 weeks, students learned nursing care using paper patients in small groups. CT disposition and CT ability were measured before and after the intervention. A scale for measuring CT disposition contains 7 subscales which are truth-seeking, open-mindedness, analyticity, systematicity, etc. Two other scales were used for measuring CT ability. One of the scales is to measure nursing CT ability. This includes 26 items which are self-awareness, independence, problem-solving skills, communication skills, etc. Other scale is to measure interpersonal CT ability. This includes 7 subscales which are understanding of essential point, understanding of diversity, considering evidence, understanding of other people, etc.
Results : No significant difference in CT disposition was observed after the intervention. In nursing CT ability, fifteen of 26 items, including problem solving skills, communication skills, confidence in evidence utilization etc, showed significant improvement after the intervention. In interpersonal CT ability, all 7 subscales were significantly improved. Systematicity, a subscale of CT disposition, showed a stronger correlation with improvement in CT ability score than the other dispositions.
Conclusion : It is not easy to improve CT disposition. The present results suggest that nursing students are able to gain a more skeptical attitude, problem-solving, communication, and learning skills, decision making ability, and confidence in evidence utilization through this educational intervention. Systematicity is an important aspect of CT disposition for the improvement of CT ability.
