Abstract: There is a problem that becomes attention to the learning of mathematics at the base in higher education and understanding of the concepts and education of student characteristics. The creative character requires that each foundation must master the concept with good and true as a matter of studying the following materials. In addition to understanding the concepts needed to pay special attention are the student characteristics. One of the negative impacts of the development of world technology has been the moral degradation of students. To overcome the problem, learning is needed which can increase the understanding of concepts as well as the education of student characteristics. One of the ways in which lesson implementation is in learning basic education. Lesson study of learning basic mathematics with a character education approach facilitates the resolution of learning problems. The reflection phase in lesson study explored all findings in the implementation of learning and provided solutions for the implementation of further learning. The aim of reflection is to obtain learning that gives attention to the development of student character. This study used a descriptive qualitative research method that describes the reflection of basic mathematics learning, anti-derivative material, with a character education approach where the learning process used constructivist learning methods assisted by Student Worksheets which the implementation program of student learning in the field technology program. Reflection results indicate that this learning has provided an increase in understanding concepts and developing student characteristics. The results of the understanding are obtained 1) 83.33% of students can restate the concept of derivative definition, 2) 76.2% of students were able to explain verbally about concept discovery, 3) 80.95% of students are able to apply the concept in solving problems given. The character values that arise when implementing learning are hard work, responsibility, discipline, curiosity, independence, tolerance, creative, uplifting, democratic, communicative, and confident. While honesty is still lacking. For further research, it can be investigated about solutions to improve the value of honesty character in basic mathematics learning.
