Abstract

This research is descriptive research using a qualitative approach. This research aims to describe the results of students' answers in solving mathematics story problems on fractional number operations based on Polya's steps in class VII SMP. Three research subjects were selected using a purposive sampling technique. Data collection was carried out using tests and non-tests (interviews). The test questions in this research are description questions, which consist of three questions. Based on the research results, it was found that (1) students were not able to understand the problem because students were unable to determine the information they knew and ask; (2) Students have not been able to make a solution plan because students have not been able to make a solution plan based on the information known and asked about the question; (3) Students have not been able to complete the completion plan because the students made a mistake in using the correct formula and were unable to complete the plan they had made; (4) students have not fulfilled the re-checking stage because students do not re-check the results they have obtained and are not sure about the answers.

Abstract

A number system is a system representing numbers. The study was ethnography research. This study explored the counting system Hubula communities use in their daily activities. There were three Hubula indigenous people as participants. Using in-depth interviews, observations, and documentation, the data was from Hubula’s indigenous people. The results of this study indicate that the order of numbers is only one to ten. The base numbers consist of one, two, and three, while the four to ten are repetitions of basic numbers. For naming the numbers five and ten, the Hubula communities use the expression of the finger-fold position, one hand for five and two hands for ten. They also recognize odd and even numbers. The odd number is one, three, five, seven, and nine, while the other is two, four, six, eight, and ten.
