This research was mix methods research with triangulation concurrent model. The population in this research was VII grade students of SMP N 3 Ungaran academic year 2017/2018. The sample was the students of VII-I class. Particularly, the subject of this research was the students of VII-I class who have high, medium, and low mathematical disposition category. This research used quantitative data to test the average of one group and the proportion of the other group. Further, the qualitative data were analyzed by Miles and Huberman model. In the process of the interview, there were two subjects in each mathematical disposition category. Eventually, the result of this research showed that the learning process by using Anchored Instructions (AI) model reached the learning mastery and described the ability of students' creative thinking with Anchored Instructions (AI) model reviewed from mathematical disposition. It was proven through the students with high mathematical disposition who had all of the aspects of mathematical disposition ability namely fluency, flexibility, and novelty. The students with medium mathematical disposition had fluency and flexibility aspect of mathematical disposition ability. The last, the students with low mathematical disposition only had one aspect of creative thinking ability that was fluency. © 2019 Published by Mathematics Department, Universitas Negeri Semarang 1. Introduction Education is an important thing which every nation should have. It has an important character in the process of increasing the grade and quality of human intellectuality in a nation. One of the purpose of management and organization education is to be the base of students' potency development in order to be educated, skillful, critical, creative and innovative human. This case is in the same line with the purpose of mathematical learning given since elementary school up to college. The mathematics subject is given to the students as the equipment with logical thinking ability, analytical thinking ability, systematical thinking ability, critical thinking ability, creative thinking ability and teamwork ability (Depdiknas, 2006). In the process of increasing the students' potential, the critical thinking ability is urgently needed. Solso as cited in Siswono (2004) explains that critical thinking is a cognitive activity which produces a way or a new thing in the view of a problem or situation. According to Silver as cited in Siswono, there are three key components in creative thinking. They are fluency, flexibility, and novelty. The critical thinking ability is because it has been one of the determinants of national excellence. The competitive power of a nation is very determined by the creativity of human sources. Based on Mahmudi (2010), the development of creative thinking ability is very important in the work. Although it is important, it does not work very well by the Indonesian Students. It was proven by the result from Trends in International Mathematics and Science Study
