Abstract
This research aims to know the quality of instrument proved through the construct validity and construct reliability of korfball-playing skill assessment. This research and development applied the modified development model of Strand & Wilson. The performance control sheets were used as the main instrument to observe the korfball-playing skills. The data were analyzed using the Exploratory Factor Analysis (EFA) technique, which is prolonged by the Confirmatory Factor Analysis (CFA) technique to make a good instrument for performing korfball-playing skills observation. The EFA analysis uses software support of SPSS 23.0 and CFA analysis uses software LISREL 8.8. This research is obtained that the estimation of construct of reliability is reliable, where the result of estimation of reliability use confirmatory factor analysis in the indicator of skill execution as well as decision making which are about 0.80 to 0.88. This research is also obtained of construct of validity is valid, where the result of estimation of validity use confirmatory factor analysis in the indicator of skill execution which are about 0.87 to 0,95. Estimation of validity in the indicator of decision making is about 0.73 to 0.79. The result of this research shows that the instrument which used to measure korfball-playing skill is considered valid, reliable, and meets the criteria of a good instrument which shows that the developed assessment model is fit to the actual data.
Highlights
Korfball is a game that is relatively new to Indonesia
The calculation of data analysis exploratory factor analysis, assisted by SPSS 17 is as follows Table 1
In the type II regulation of cardiac rhythm there is a significant decrease in expiratory duration (s), which is manifested by a significant increase in the ratio of inspiratory and expiratory phases, which may characterize expiratory insufficiency for this type[10]
Summary
Korfball is a game that is relatively new to Indonesia. The game of korfball requires a field with an area of 40 M x 20 M. This game uses a ball and a basket with a height of 3.50 meters as the target. One team consists of 6 male players and 6 female players. Each team must split the players into 2 male players and 2 female players to play on the defensive field, and 2 male players and 2 female players in the attacking field. The remaining players, 2 male and 2 female players are the substitutes[1]. The basic skill of korfball player consists of shooting, passing, and rebounding
