An expert in the field of science is often difficult to teach his knowledge to students. Conversely someone who is expert in the field of education is certainly more expert in transferring knowledge. The purpose of this research is to explore the skill of teaching skill preservice of physics teacher of High School. Samples were taken randomly as many as 50 people in two universities in Indonesia. The data collection used a Self-Regulated Leaning Based on Learning Style (SR2LS) questionnaire to detect their teaching skills through learning styles. The management of the learning class depends largely on the teacher's mastery of teaching materials. A good teaching strategy is needed in teaching abstract concepts to be more effective for students to understand. Students will experience misconception if the concept of teachers is not understood by students as in the lessons of the concept of atoms. Material physics is one of the lessons about the concept of atoms. The results showed that 60% of students had a "visual learning style", 30% "visual" and 10% "kinesthetic". Most preservice teachers can tailor their teaching strategies according to their own learning styles. But most of them have difficulty in analogizing the abstract concept on the atom.
