Abstract

This research aim’s to describing student’s learning trajectory based on student’s learning outcomes (high, middle, and low) in mathematics especially for scale subject matter. This research using qualitative descriptive method. The subject of this research is students with high, middle, and low learning outcomes with two person for each categories. The research is using test, interview, and observation. The result of this research is (1) Students’s learning trajectory with high learning outcome is understanding the scale subject with his intuition. (2) Student’s learning trajectory with middle learning outcome is understanding the scale subject with its concept. (3) Student’s learning trajectory with low learning outcome show that the understanding of scale subject concept was low. They finding the number of the scale aprropiate with its concept but they didn’t know why they using this mathematics model. The different student’s learnnig trajectory based on student’s learning outcomes is student with high learning outcomes finding the scale with his own way based on concept, students with middle learning outcomes finding the scale appropiate with what his learn in class, and students with low learning outcome finding the scale appropiate with mathematics model but they didn’t know the concept clearly.
