Validation of written and video based assessment instruments in physical education

Abstract

A written paper (WP) and a video-based-paper (VP) were used to measure the learning outcomes of three experimental teaching units (ETUs) of athletics. The subjects (n=49) were 16 year olds. The ETUs represented three teaching environments; practice, practice and handouts, and classbased sessions. Pre and post-tests were administered for the content of rules, planning tactics and techniques. Rasch model analysis showed that both tests were unidimensional and reliable (R ranged from 0.86 to 0.92). The efficiency of the three experimental teaching units was evaluated by means of paired sample t-tests. The subjects performed better on the posttests (WP: effect size=1.2 and VP: effect size=0.93). The pre-tests and posttests abilities of the subjects were highly correlated (WP: r=0.380 and VP: r=0.322). The subjects of the class-based sessions achieved significantly better scores on all content areas when video based assessments were used. The findings of this study are applicable to athletics.
