The general purpose of this action research is to describe the effectivity of the direct instruction (DI) model application in increasing the university students’ potential scientific basis in Basic Physics 2 under the subject of basic electrostatics. To study the materials and solve the problem of physics in this lecture, the scientific basis competence in the form of procedural skill and declarative knowledge is needed. The research result has shown that the effectivity of the instruction application in increasing the university students’ scientific basis competence is 76,4% in the effective category. It is suggested that in the lecture of Basic Physics 2, it is best for the lecturer to apply the direct instruction (DI) model, especially in increasing the university students’ scientific basis competence in depicting, presenting, and explaining the meaning of the basic physical formula of Physics. Key Words: scientific basic competence, basic physics 2, and direct instruction
