The study aims to investigate the teachers' conceptions about the teaching and learning and the influence on their practice. The subjects were two mathematics teachers who taught in the 7th grade junior high school students in Sukoharjo, Central Java with diverse mathematical ability. The data was collected through observation and interview. The triangulation was conducted to validate the data. Then, the data were analyzed using three stages, namely, data reduction, data display, and drawing the conclusion. The results showed that there were different teachers' conceptions about the teaching and learning of the two teachers. The first teacher following the traditional model where he plays as a source of knowledge. The students are passive learners who receive knowledge from the teacher. In teaching practice, the teacher presents the material with the expository method. Learning emphasizes the student's skills to operate the calculation. Conversely, the second teacher conceptions' in line with the constructivist pattern where she plays as a facilitator and student guide in the learning process. The students are active learner where they discover the knowledge collaboratively. The learning activities involve group discussions and presentation. The results suggest that there is an influence on the teachers' conceptions and their teaching practice. © 2019 IOP Publishing Ltd. All rights reserved.
