A study of supplemental CAI effects on dosage calculation test scores of low- and high-aptitude/achievement baccalaureate nursing students
Abstract
This study was designed to examine the effect of a researcher-written, supplemental computer-assisted instruction (CAI) dosage calculation drill-and-practice program on dosage calculation test scores of low- and high-aptitude baccalaureate degree nursing students. Specifically, the study sought to determine, first, if nursing students derive benefit from a supplemental CAI dosage calculation program, and, second, if low-aptitude/achievement nursing students derive greater benefit than high-aptitude/achievement nursing students from the program. The research sample consisted of 60 baccalaureate students enrolled in a first-year nursing class at a major midwestern university. The study employed a 2 x 2 factorial design (high-aptitude/achievement vs. low-aptitude/achievement) (supplemental CAI vs. no CAI). One-half of the 30 high-aptitude/achievement and one-half of the 30 low-aptitude/achievement subjects were randomly selected to use the CAI program. The subjects' scores on a dosage calculation exam was the dependent variable in this study. This study posed five research hypotheses and three ancillary questions. Analysis of the data resulted in the following conclusions. (a) Method of instruction is related to student performance in dosage calculation testing: Students who used the CAI program attained higher test scores than those who did not. (b) Student aptitude/achievement is related to student performance in dosage calculation testing: High-aptitude/achievement students attained higher test scores than low-aptitude/achievement students. (c) Low-aptitude/achievement students derive greater benefit than high-aptitude/achievement students from the CAI program: Low-aptitude/achievement students who used the program attained higher test scores than those who did not; high-aptitude/achievement students who used the program did not attain higher test scores than those who did not. (d) Students have a positive attitude toward the use of supplemental CAI programs: Students who used the program had a favorable attitude toward the program; low-aptitude/achievement students had a more positive attitude toward the program than high-aptitude/achievement students.
