Abstract

This study aims to describe students' errors in solving algebra problems in class VII A of SMP Negeri 3 Dampelas. This research employs a descriptive method with a qualitative approach. Three students from class VII A were selected as research subjects, focusing on conceptual and procedural errors. The identified errors include mistakes in concepts, principles, and facts. Conceptual errors involve misconceptions in the addition of like terms. Principle errors occur when students incorrectly conclude the final answer. Factual errors involve mistakes in writing variables. Procedural errors include general mistakes, arithmetic operation errors, and errors in simplifying algebraic fractions.

Abstract

This research is classroom action research that aims to improve student learning outcomes by using the drill and practice method in the direct learning model. The application of the direct learning model follows the following phases: 1) conveying the objectives and preparing the learners, 2) demonstrating knowledge or skills, 3) guiding the training, 4) checking understanding and providing feedback, and 5) providing opportunities for further training and application. This research was carried out in as many as two cycles by following predetermined stages. The subject of this study is 7th-grade students of SMP Negeri 1 Sindue Tobata, with a total of 23 students. The results of the research from Cycle I and Cycle II showed an increase in student learning in integer counting operations learning using the drill and practice method in the direct learning model, namely in Cycle I by 60.8% and in Cycle II by 87%. Therefore, the drill and practice learning method can improve student learning outcomes in learning integer counting operations.

Abstract

The purpose of this study is to describe the mistakes of male and female students in solving numeracy AKM problems based on Newman procedures. The method used in this study is a qualitative descriptive method. Some of the results obtained from this study are: (1) mistakes made by male students including comprehension errors occurred because students read the questions once quickly and did not know which ones to write because the questions were too long, process skill errors occurred because students were not careful in calculating multiplication and division operations, and encoding errors occurred because students were in a hurry to do the problems; (2) mistakes made by female students include comprehension errors occurring because students read the questions once and do not know which ones to write because the questions are too long, transformation errors occur because students do not know the formula for finding averages, process skills errors occur because students are not able to calculate correctly, and encoding errors occur because students are not careful in reading what is asked in the questions.(3) The most dominant mistake made by male and female students is comprehension error. This mistake occurs because students read the questions only once, making them unable to fully understand the information provided in the questions and not knowing which points to write down due to the questions being too lengthy.
