  • . Based on this problem, a learning model is developed that can improve student competence, especially refereeing material. The model developed in this research is a learning by doing model. The method used in developing the model uses the Borg and Gall method (2007). The subjects used in this students. Data were collected through observations and questionnaires. The data analysis technique uses quantitative analysis techniques with a Liker scale percentage. Based on the results of data analysis obtained from experts related to the feasibility of the by doing learning model for volleyball refereeing material. It can be seen that expert 1 assesses the model by doing from the objective aspect, material aspect and fit aspect of the model to have a percentage level of quality of 90.8% or very good. Then for expert 2 assessing the model by doing from the objective aspect, material aspect and model fit aspect, it has a quality percentage level of 93.4% or very good. Thus, it can be stated that the by doing model deserves to be continued for field trials to determine the efficiency and effectiveness of the model.
