To achieve the purpose of the study was to examine the segregated and collaborated effect of computer supported and traditional methods of training with small side games on selected psychomotor and performance parameters among school basketball players. For that sixty (60) school level basketball players were selected as subjects from Municipal Boys Higher Secondary School, Salem, Salem District, Tamil Nadu, India. The age of the subjects was restricted to 14 to 18 years. The selected subjects were randomly assigned into four groups of fifteen each group I underwent Computer Supported Collaborative Training with Small Side Games Group (CSCTSSGG), group II underwent Traditional Method of Training with Small Side Games Group (TMTSSG), group III underwent Combined Computer Supported Collaborative and Traditional Method of Training with Small Side Games Group (CCSCTMTSSGG) and group IV acted as Control Group. The experimental groups underwent a six-weeks training program of three alternate days per week, ninety minutes per session. The computer supported collaborative training with small side games group received computer-based video demonstration, video analysis (kinovea) and feedback based basketball skill training integrated with small side games, while the traditional method of training with small side games group performed skill development such as demonstration and repetitive drill execution and over the progressive drill based training such as dribbling, passing and shooting. Combined Group will collaborate with the two groups. The control group did not receive any specific training apart from their regular physical activities. The pre and post test data were statistically analyzed using dependent t-tests and ANCOVA at the 0.05 level of significance. The results revealed that all the experimental groups significantly improved in psychomotor and performance parameters
