Development of Machining Technology Material by Using Teaching Factory Based on Metacognitive Skill Model

This research is to develop learning material of machining technology with Teaching Factory Model approach based on metacognitive skill on Mechanical Engineering Education in Universitas Negeri Medan. The method used in research and development is development design of ADDIE. The results show that machinery technology lecture with Teaching Factory Model approach based on metacognitive skill is proper to be used with practicability level reach to 80.39%, and it is effective because resulting significant differentiation of study result value between experimental class and control class based on result of t experimental with value of tarithmetic = 2.72 and ttable = 2.021. Thus, Machining Technology Textbook by using Teaching Factory Based on Metacognitive Skill Model can be used practically and effectively in the learning process.
