title: Comparison of two methods for teaching advanced arrhythmias to nurses.
abstract: An experimental study to compare the effectiveness of assisted self-directed learning (ASD) and traditional lecture methods (TLM) in acquiring competency for electrocardiogram interpretation was conducted within a conceptual framework of developmental and adult learning theory (Erickson, Tomlin & Swain, 1983; Knowles, 1980). After two teaching units were designed and an EKG posttest was constructed (r = .75) from actual patient records, registered nurse volunteers (N = 19) were randomly assigned to groups for simultaneous instruction. Because of the small sample size, statistical procedures were used to determine the effectiveness of randomization and to justify statistical procedures. EKG post-test scores for the experimental group (ASD, M = 81) and the control group (TLM, M = 71) were significantly different (one-tailed t = 1.79; p = .045); however, participants' prior knowledge of basic arrhythmias was not independent of method (ANCOVA, F[1, 16] = 21.373, p = .0003, covariate; F[1.16] = 2.312, p = .1479, main effects). EKG post-test scores were not related to critical care experience, cardiac monitoring experience, education level, or course satisfaction. While both methods are effective, ASD had higher mean scores and is more cost- and time-efficient.
