Control and rationalism value in mathematics modelling

Learning Mathematical modelling is an important part of mathematics. However, it is difficult to apply in learning. This research is a descriptive study with the aim of studying the learning process of mathematical modelling using worksheets (LKS) based on control and rationalism values in Junior High School Number 13 Palembang. The research subjects consisted of 37 students of class VIII.2. Data collection techniques in this study consisted of observation. Observations were made to see student activities which are appearance of control and rationalism value during the learning process and student activities using worksheets. The results of the study were obtained from student activities based on indicators of control and rationalism value during learning process with an average of 78.375 which were categorized as good result. Besides that, we observe control and rationalism value on worksheet with average of 77.79 which were categorized as good result. All learning processes use modelling stages only at the second meeting the stages of understanding the problem do not arise because the problem used continues from the problem at the first meeting so that it does not result in the emergence of control value indicators in understanding the problem.
