ABSTRACT
The purpose of this study was to develop and design backspin serving skill tests to assess the learning outcomes of table tennis serving skills. The study employed the following research and development methods: (1) Developing the design and construction of backspin serving skill tests and testing the content validity of the design and construction of the backspin serving skills of table tennis game, (2) Searching for empirical validity and reliability of the backspin serving skill tests. The subjects of the study were students studying table tennis. The data analysis involved content validity ratios, product moment formulas and Cronbach’s Alpha formula. We showed that (1) the content validity of the test was high (content validity ratio = 0.90) with the design and construction of three target marks on the table: the first area (152.5 cm x 35 cm) was scored 5, the second (152.5 cm x 35 cm) was scored 3, and the third area (152.5 cm x 67 cm) was scored 1 with a string set across the table 20 cm above the net. This string was attached according to the procedures of the test and scoring guide, (2) the empirical validity was 0.893, and the reliability was 0.938 for students studying table tennis serving. The design and construction of this backhand serving test can be used to assess learning outcomes of table tennis serving skills.
