Abstract
Pre-service Physics teacher are required to have mathematics procedural ability in solving definite integral problems, because many physics phenomena are related to definite integrals. Besides that ability, they are also expected to have the ability to formulate general procedures in solving them, because this ability is a high-level ability that needs to be trained. So, the aim of this study is to obtain description about the ability of pre-service physics teachers in formulate a procedure of integration by substitution focused on indefinite integrals. This study used qualitative description approach with pre-service physics teachers at one of universities in Palembang, South Sumatera as research subject. It was 12 pre-service physics teachers who take basic mathematics lectures in the first semester. To collect the data, this study used documentation and interview to verify it. The results showed that the procedure formulation is divided into two types- the first type of formulation is still specific by using one particular example, while the second type is general, but both types describing each step are still unclear, and there are some mathematical errors.
