The first two studies employed an ex-post facto research design with convenience sampling. The sample of student scores in the two studies numbered 1,544 and 3,347, respectively, and these scores were obtained from the total set of scores of students at schools of nursing in programs leading to RN licensure where the electronic case studies were purchased in 2004 and 2005. The students' mean E˛ scores were compared with those of students (N = 21,241) who did not use the Apply case studies. Paired samples t-test demonstrated a significant difference (t = 9.979, p=.000) in mean E˛ scores of students who used the Apply case study scores and those who did not.
Findings indicate that Evolve Apply case study usage is associated with increased mean composite student scores on the E˛, which has also been associated with a higher probability of student success on the NCLEX-RNŽ. The third study will include descriptive data supplied by schools of nursing related to the application and use of Apply case studies in their curricu
