ABSTRACT

The groundstroke is the basis of the game of court tennis which determines the control of the court and the ability to defend and attack in a match. For professional athletes, mastery of groundstroke technique and consistency are key to controlling the game and winning important points. The purpose of this study was to develop a valid and reliable assessment instrument to measure basic groundstroke technique skills in junior tennis players. This instrument is expected to help coaches evaluate athletes' abilities objectively and develop more effective training programmes. The method used in this research is Development or Research and Development (R&D). The development of this instrument uses the ADDIE model. The samples in this study were 30 beginner-level junior tennis players aged under 15 years. The ADDIE model analyses the target user athlete to ensure the instrument developed is as needed, designs an assessment instrument that includes indicators of basic groundstroke technique skills including the assessment format, measurement scale, and guidelines for use and is tested for validity and reliability through a limited trial. Validation results showed high content validity (Aiken's V= 0.83-1.00) and strong internal consistency (Cronbach'a Alpha =0.864). These findings confirm that the instrument is both valid and reliable for evaluating the technical proficiency of beginner tennis players. The instrument is practical for use in real training settings and offers coaches a structured tool to assess, monitor, and improve players' technical development. Further refinement and testing with a larger sample are recommended to enhance its applicability and reliability.
