Abstract

The purpose of this study is to describe the completion of arithmetic operations, multiplication and division of algebraic forms for students of SMP Negeri 18 SPMI Palu. This type of research is qualitative research. The subjects in this study were 2 students taken from 32 grade VIIA students of SMP Negeri 18 Model SPMI Palu. The results of this study indicate that the completion of students with high mathematical abilities in solving arithmetic operations problems of multiplication and division of algebraic forms, namely: (1) ST writes the given problem, changes the problem using distributive properties so that the results are obtained. But on the results of the ST distributive property, they did not write down the number sign because they forgot to write it down. Then perform multiplication operations, add up similar terms and get the final result, (2) ST writes down the questions given, performs tiered division operations so that the results are obtained. Completion of students with low mathematical ability in solving arithmetic operations problems of multiplication and division of algebraic forms, namely: (1) SR rewrites the given questions, grouping similar terms, operating like terms so that the results are obtained. However, SR incorrectly determines the result of an integer operation. This is due to SR's inaccuracy when operating, (2) SR wrote questions, did not perform tiered division operations so that the results were obtained.

Abstract

This study aims to obtain a description or description of the mathematical literacy of class VIIIA students of SMP Negeri 19 Palu on statistical material. This type of research is descriptive with a qualitative approach. The subjects of this study were students of class VIIIA SMP Negeri 19 Palu who had a visual learning style with the initials ID and auditory with the initials FR. Data was collected through written tests and interviews. The results of this study indicate that the profile of students who have a visual learning style (ID) in solving statistical problems are: (1) ID identifies any information that is known and asked in the question; (2) ID writes down known data using symbols and writes the average in the form of verbal sentences; (3) ID uses the mean or mean formula and substitutes the appropriate data; (4) ID writes the conclusion correctly. Then, the results of this study also show that the profiles of students who have an auditory learning style (FR) in solving statistical problems are: (1) FR identifies any information that is known and asked in the question; (2) FR writes down the known and average data in the form of verbal sentences; (3) FR uses the mean or mean formula and substitutes the appropriate data; (4) FR writes the conclusion correctly.

Abstract

This study aims to obtain a description of the types of errors made by class X students of SMA Negeri 1 Sarudu in solving absolute value equation word problems based on Watson's criteria. This type of research is descriptive research with a qualitative approach. The subject of this research was taken by three students out of 18 students consisting of two students who made many mistakes and one who made few mistakes. The results of this study were (1) the types of errors made by subjects who made the first mistake in solving absolute value equation word problems were inappropriate procedure, and omitted conclusion. (2) the type of mistakes made by subjects who make a lot of second mistakes in solving the absolute value equation story problem is inappropriate data, undirected manipulation, and omitted conclusion. (3) the types of mistakes made by the subjects who make few mistakes in solving the absolute value equation story problem are inappropriate procedure.
