Pattern Generalization Strategy From Concrete Operational Students

---

Abstract. Pattern generalization played an important role in the introduction of early algebra
which became a bridge between arithmetic and algebra. However, there are still many students
who have difficulty in generalizing patterns. The difficulty of students in generalizing patterns
lies in the steps of producing general formulas. Students find it difficult to represent
generalizations in the form of variables-n. In addition, students also find it difficult to justify
the resulting generalization. This difficulty is experienced by concrete operational students. For
this reason, this research aims to study students' concrete operational thinking processes in
generalizing patterns. The results of this study provide effective learning strategy solutions for
concrete operational students in generalizing patterns. This research is a qualitative research
with a case study approach to junior high school students. The results indicated that concrete
operational students looked patterns represented in the form of geometric drawings globally
without looking the structure of the images. Concrete operational students use two strategies in
generalizing patterns, namely the guess and check strategy and the explicit visual strategy
