Abstract

The purpose of this study was to seek the validity and reliability of net game’s performance-based assessment on the context of elementary school physical education students’ achievement. Research and development used as a primary research method. The subject were forty students in Yogyakarta’s table tennis school club which chose through random sampling technique. Content Validity Ratio (CVR) is used to test the validity, on the other hand, Anava-general Multifacet model for the inter-rater reliability. the results were as follows: CVR of the decision making is 0.714; CVR of the skill acquisition process is 1; CVR of the skill acquisition product is 1; and CVR of the returning on beginning position is 0.714. as for the decision making inter-rater reliability r = 0.785; skill acquisition process reliability r = 0.872; skill acquisition product r = 0.785; and returning on beginning position r = 0.885. As the conclusion, performance-based assessment instrument of net game, particularly table tennis, has high scores of validity and inter-rater reliability.

Performance-based assessment instrument developed for the net game, particularly table tennis have been tested with high value content validity and reliability. It can be concluded that the performance-based instrument for table tennis is a valid and reliable instrument in measure elementary student acquisition on the table tennis.
