Development of Freestyle Swimming Learning Model Based on Static Swimming Tools

This study aims to: 1). Find a freestyle swimming learning model based on static swimming tools, 2). Researching the effectiveness of free style swimming learning models based on static swimming tools. Research uses the R & D methodology (research & development) which refers to the ten stages of development introduced by Wolter R. Borg and Meredith D. Gall. Through this method a freestyle swimming learning model is produced based on static swimming tools. The effectiveness of the freestyle swimming learning model was obtained through the experimental research design in the form of Randomized Pretest-Posttest Control Group. The study was conducted on sports coaching education students at the Faculty of Sports Science, State University of Medan, semester 1 of Academic Year 2017-2018 conducted at the SCC State University of Medan swimming pool in the field. To the test effectiveness of freestyle swimming learning models based on static swimming tools, the method used is to compare the results of the pre test and post test. Data from the pretest and posttest swimming skills were generated based on the freestyle swimming test instrument with reliability 0.83 with a high positive correlation interpretation. The research subjects were 40 people for the experimental group and 40 for the control group. Data is processed using statistical procedures with steps; determine the average difference, determine the standard deviation is different and determine the effectiveness of the model with t test statistics. Based on the calculation of the experimental group data, the results of t arithmetic = 21.54 and t table = 1.70, resulting in a meaningful test. Then the product learning model effectively improves freestyle swimming skills. The increase in freestyle swimming skills is known by the normalization average analysis procedure (average normalized gain) with the results of low criteria 7 people (17.5 %), medium criteria 33 people (82.5 %) and 0 % high criteria. To find out the differences in the learning outcomes of swimming between the two groups, use statistical procedures with steps; determine the combined standard deviation of the two groups, and determine the value of the paired t test. Based on the statistical analysis of t test, obtained t count = 2.52 and this value is greater than t table = 1.70 means that there is a significant difference between freestyle swimming skills between the experimental group and the control group.
