An analysis of students' difficulties in conjecturing process of block paving problems

Abstract

This study aimed to describe students' difficulties in the conjecturing process of block paving problems. The subjects used in study were 32 of 8th grade students of Junior High School. The data were collected using Block Paving Problems (BPP) and interviews. Data collection procedures consisted of two stages. The first stage was the researchers had the student solved BPP while think aloud. The second stage is task-based interview to explore information needed to confirm from the results of think aloud. The result of study revealed that 1) difficulty in interpreting the pattern of, n, 2) The difficulty in finding and predicting the next pattern based on regularity, 3) The difficulty in finding and predicting the next pattern 4) The difficulty in Forming Pattern of n.
