EFFECT OF SKINNER'S LEARNING THEORY WITH PICTURE AND PICTURE MODEL ON THE ABILITY OF MATHEMATICAL UNDERSTANDING OF STUDENTS IBNU HAJAR MANDIRI

Mathematics is often considered a scourge for the field of study that is considered difficult and boring, the learning carried out is teacher-centered where students are less active and only accept the learning delivered by the teacher. Based on this background, the purpose of this research is to find out the improvement of students' mathematical understanding skills whose learning uses Skinner's learning theory through picture and picture models, to find out the differences in students' mathematical understanding abilities who use Skinner's learning theory through picture and picture models with those who do not use Skinner's learning theory but through the picture and picture model, and knowing the student's response to learning using Skinner's learning theory through the picture and picture model. The research method used is a true experimental method with a population of all eighth-grade students of Ibnu Hajar Mandiri Bekasi Junior High School for the 2020/2021 academic year. Sampling was done purposively. The instrument is a test about the description of students' mathematical understanding abilities on function material and questionnaire sheets. The results showed that learning mathematics using Skinner's learning theory through picture and picture models can improve students' mathematical understanding skills, besides that there are differences in the mathematical understanding of students whose learning uses Skinner's learning theory through picture and picture models with students whose learning does not use Skinner's learning theory but through picture and picture models. The student's response after using Skinner's learning theory through the picture and picture model was considered good. This shows that only a small number of students still consider mathematics a very difficult and boring subject.
