Abstract
Background
A digital book may support learning instrument names and functions, but knowledge scores do not establish practical competence.
Objective
To compare immediate posttest instrument knowledge between INSTADAN and lecturer PowerPoint groups after baseline adjustment.
Methods
This nonrandomized study analyzed 161 first year midwifery students from four intact classes (INSTADAN, n=78; control, n=83). A 30 item knowledge test was administered before and after teaching. Individual level ANCOVA adjusted for pretest score, age, and information sources with HC3 standard errors.
Results
Mean scores rose from 68.72 to 85.04 with INSTADAN and from 68.84 to 79.88 with PowerPoint. The adjusted difference was 6.08 points (95% CI, 3.99 to 8.17; P<0.001), equivalent to approximately 1.82 correct answers. Student stratified bootstrap gave a 95% interval of 4.05 to 8.14 points. Neither method adjusted for class dependence.
