Validity and Reliability of Sport Diving Basic Skill Instrument for Beginner Diver

Abstract

The aim of this study was to validate the instrument used to assess the students' basic knowledge and skills in sports diving. Currently, many training programs are offered by agencies and coaches, and the need for assessment tools to be more objective assessments for beginner diving that meet the requirements for learning achievement in terms of student knowledge and skills. This research uses mixed methods. This study combines two approaches, namely qualitative and quantitative. The six experts' participation was determined by criteria of sport diving and Sport aquatic expert. The qualitative stage for data collection uses the Delphi technique. This research was conducted with content validity with Aiken's V index. Reliability test using Cronbach's Alpha Reliability Test. Aiken's analysis results on the instrument of knowledge and basic diving skills. Based on research results, Aiken's V index stated that the instrument for assessing basic diving knowledge and skills compiled is valid. Furthermore, Cronbach's Alpha reliability test on an interrater assessment of 6 raters, it was found that the overall Cronbach's Alpha value on the test subjects was declared reliable or consistent. Based on the research that has been done and the discussion that has been described, an instrument of knowledge and basic diving skills have high content validity and reliability between raters. It can be concluded that the instrument tool can be used by dive trainers or diving sports teachers in ensuring sufficient skills provision for the safety and comfort of diving in the future and an overview of further self-development regarding the branch of diving expertise through professional training, especially for students of the UNY sports science faculty.
