Procedural fidelity is defined as the extent to which the independent variable is implemented as prescribed. Research using computerized tasks has shown that fidelity errors involving consequences for behavior can hinder skill acquisition. However, studies examining the effects of these errors once skills have been mastered are lacking. Thus, this…

The study investigated the effectiveness of using visual cues to highlight the seams of baseballs, to improve the hitting of curveballs by five undergraduate varsity baseball team candidates. Results indicated that subjects hit a greater percentage of marked than unmarked balls. (Author/DB)

This study evaluated the importance of active student responding while using the microcomputer to deliver the contingencies of programed instruction. Results from 75 undergraduates found that students who covertly responded to frame blanks or were required to type frame answers performed better on a posttest than students who passively read…

The use of overt answer construction in computer-based programmed instruction was studied. Four college students completed an instructional program that alternated between presenting frames with blanks requiring overt responses and complete frames without blanks. All students produced more correct answers corresponding to program segments that…
