Abstract

The aim of this study was to obtain a description of the analysis of the argumentation abilities of class VIII students at SMP Negeri 6 Palu on function. This type of research is descriptive research type. The approach used in this study is a qualitative approach. The subjects of this study were three students in grade VIII of SMP Negeri 6 Palu for the 2021/2022 academic year. Students at a high level of mathematical ability have good argumentation skills because they are able to state what information is in the problem and at each step of completion (Data), are able to provide statements to solve a problem (Claim), are able to show data as well as provide evidence that is able to support statement put forward (Warrant), and able to reject the statement and explain the conditions under which the statement is not valid (Disclaimer). Students at the moderate level of mathematical ability have fairly good argumentation skills because they are able to provide statements to solve a problem (Claim), are able to show data as well as provide evidence that is able to support the statements put forward (Warrant). Students at low ability levels have less argumentation skills because they have not provided enough information about what is in the problem and at each step of completion (Data), have not been able to provide statements to solve a problem (Claim), have not been able to provide evidence capable of supporting statements made stated (Warrant), and also has not been able to provide an explanation of the conditions under which the statement is not valid (Rebuttal).

Abstract

This research aims to describe the types of errors made by class VII D students of SMP Negeri 7 Palu in solving line and angle problems based on gender. Data was obtained from the results of written assignments and interviews. The research subjects consisted of one male student (AA) and one female student (YS). The results of the research show that there are similarities and differences between male and female students in making written assignments number 1 and 2. Male and female students make the same mistakes in written assignment number 1. The similarities are: 1) Errors of not understanding the concept of the relationship between angles that are supplementary to each other, 2) the error of not understanding the concept of the relationship between the interior and exterior angles of a triangle, 3) the error of not solving the problem according to the instructions, 4) the error of not being coherent in the calculation steps, 5) the error of using arithmetic operation signs, 6) Error calculating the value of a calculation operation. Meanwhile, in written assignment number 2, there were differences in errors made by male and female students. The male students' mistakes were: 1) The male students were correct in doing the questions according to the instructions but not completely or comprehensively, 2) The male students were not careful and rushed in solving the questions. The female student's mistakes in written assignment number 2 were: 1) The female student was correct in choosing the formula but could not apply the formula, 2) The female student solved the problem not according to the procedure ordered. The similarity between male and female students in completing written assignment number 2 is that in the problem solving procedure they can group similar and dissimilar terms in the written assignment.

Abstract

This research aims to obtain a description or portrayal of the conceptual understanding of 8th-grade students in class G at SMP Negeri 3 Palu in solving statistics problems, with a focus on gender differences. This study adopts a descriptive research design with a qualitative approach. The research subjects are 8th-grade students in class G at SMP Negeri 3 Palu. Data were collected through written tests and interviews. The results of this research indicate that male students have a better conceptual understanding compared to female students based on conceptual understanding indicators. Male students can fulfill four out of five indicators, while female students fulfill three out of five conceptual understanding indicators. Both male and female students can articulate the concepts of mean, median, and mode in their own words. They can present data in table form with the correct arrangement. Male and female students can solve mean problems using appropriate algorithms. Male students can classify modes, whereas female students struggle to classify modes accurately. Both male and female students find it challenging to associate the concept of median with the concept of mean.
