development model training shooting based on multiple unit offense for basketball athletes 16-18 years of age groups

the goal of this research and development is to produce and develop the effectiveness of the model of drills shooting basketball for basketball athletes 16-18 years age group. this research and development uses qualitative and quantitative approaches and uses development research methods research and development (r d) that adopt the theory of borg w. r and gall. m. d which uses 10 stages of development. the steps in this development research start from the following: (1) research and information collecting, (2) planning, (3) develop preliminary form of product, (4) preliminary field testing, (5) main product revision, (6)) main field testing, (7) operational product revision, (8) operational field testing, (9) final product revision, (10) dissemination and implementation. this development research resulted in practice model products shooting with practice manuals shooting and practice videos shooting. the results of processing normality test data with kolmogorov-smirnov and shapiro-wilk obtained the sig or the p-value of all data for kolmogorov-smirnov 0.05, h0 is accepted or not significant, means the population data is distributed normally. in addition, the results of the t-test value of the post-test experimental group and the control post-test, with the mean (mean) test results of technique shooting the basketball given the based training model multiple unit offense (experimental group) of 103.27 and the standard deviation is 12.556, which means that descriptively the ability of the technique shooting given the based training model multiple unit offense is higher and more developed than the based training model multiple unit offense. in addition, the average n-gain score for the experimental class is 158.71%, this value is included in the effective category, with a minimum value of 20.69% and a maximum value of 750.00%. while the average n-gain score for the control class is 38.76%, this value is included in the ineffective category, with a minimum value of 5.00% and a maximum value of 200.00%. thus it can be concluded that the use of techniques for shooting basketball athletes in the 16-18 year age group based on multiple unit offense is effective in improving the skills of techniques shooting.
