A CONSTRUCTION OF CRAWL STROKE AND BACK CRAWL STROKE SKILLS MEASUREMENT FOR STUDENTS OF THAILAND NATIONAL SPORTS UNIVERSITY – NORTHEASTERN REGION

Abstract

The purpose of this research was to create and validate the construction of crawl stroke and back crawl stroke skill measurements for students of Thailand National Sports University, Northeastern region. The 30 students at Udon Thani Rajaphat University were selected to validate the construction of crawl stroke and back crawl stroke skill measurements using purposive random sampling. The sample group used to create the normal criteria (benchmark) was 226 students from the Thailand National Sports University in the Northeastern region using stratified random sampling. The research instruments were crawl stroke skill measurements and back crawl stroke skill measurements. Inferential statistics include the Pearson correlation coefficient and T-scores, and then using the information obtained to create a manual for using the measurement. The results are summarized as follows:

             The results of creating swimming skill measurements for crawl stroke skill measurements and back crawl stroke skill measurements in each pose are divided into four sub-skills, including leg skills, arm skills, breathing skills, and relationship skills in swimming. There are 3 practice postures for each skill, using a 4-level rubric scoring system. The content validity (IOC) for all swimming skill measurements was at a very high level. The reliability was high to very high (.734 and .877), and the objective value of the scoring criteria was high to very high (.748 and .850). The results of creating the normal criteria (benchmark) swimming skill measurements for crawl stroke skill measurements and back crawl stroke skill measurements for students of Thailand National Sports University, Northeastern region. The criteria are divided into 5 levels: very good, good, moderate, poor, and very poor. Normal criteria (benchmark) for crawl stroke skill measurement is very good (T-score = 68 and over); good (T-score = 57–67); moderate (T-score = 46–56); poor (T-score = 36–45); and very poor (T-score = 35 and lower). Normal criteria (benchmark) for back crawl stroke skill measurement is very good (T-score = 65 and over); good (T-score = 53–64); moderate (T-score = 41–52); poor (T-score = 28–45); and very poor (T-score = 27 and lower).
