Analysis of Student's Mathematical Reflective Thinking Ability in Number Pattern

Abstract

The ability of mathematical reflective thinking must be possessed by students in Industry 4.0. This study used descriptive qualitative research that aims to determine the reflective thinking ability of senior high school students on pattern numbers. The research subjects were 10 students of class XI. Based on data analysis, it is found that: generally students could (a) check the validity of arguments based on the concepts used, (b) identify mathematical concepts used in mathematical solutions accompanied by reasons, and (c) show the difference between relevant data and irrelevant data in solving problems. Whereas only a few students can (a) generalize accompanied by reasoning, and (b) solve problems using various completion strategies.
