Abstract

This study aims to analyze the difficulties of SMPN 02 Cililin students in solving algebra word problems in terms of students' ability levels. By understanding students' ability levels, educators can identify difficulties faced by students and develop appropriate teaching strategies to increase their understanding. This study uses a qualitative and descriptive research strategy by analyzing the difficulties experienced by students using the instruments provided. The research subjects taken were class VII students of SMPN 02 Cililin with a total of 20 students. The results of the analysis show variations in the level of students' ability to solve algebra story problems. Students with high abilities are able to correctly identify relevant variables, model mathematical relationships correctly, and reach accurate solutions. Students with moderate abilities can usually understand basic algebraic concepts, but they still need to improve their mathematical modeling and problem solving skills. Students with low abilities often have difficulty understanding basic algebraic concepts and applying them in the context of word problems.

Abstract

This research looks at how difficult it is for grade VIII students of junior high school in working on statistical problems in terms of gender. Qualitative descriptive method was used for this research. 8 students consisting of 4 male students and 4 female students from Madani Middle School in Cihampelas were used as research subjects. The instrument used in this research has four items in the form of descriptions. The results of student test scores based on statistical question instruments are used in collecting research data, with indicators; 1) evaluating the accuracy of the data provided, 2) determining the mean value of a data, 3) analyzing data in the form of diagrams, 4) solving problems to draw a conclusion. Based on the analysis and discussion of the 4 questions describing the statistics material, it can be concluded that the ability of class VIII male students at Madani Middle School in working on statistical problems is still weak compared to female students. The students' lack of understanding of the basic concepts of statistics, the inability to understand the meaning of the questions, and the difficulty in finding strategies to solve problems are the contributing factors.

Abstract

The study aims to analyze the ability of mathematical connections in a sequence and series of materials conducted when learning offline after previously applied online learning. This type of research is qualitative with data collection techniques, namely mathematical connection ability tests and interviews. The subjects of the study consisted of 4 class XI SMK students in Bandung Regency who had previously studied sequence and series online. Analysis carried out on mathematical connection ability seen from indicators of connection ability is understanding the equivalent representation of the same concept or procedure, looking for connections with procedures to other procedures in equivalent representations, using mathematics in everyday life and using connections between mathematical topics, and between mathematical topics and other topics. The results of the analysis conducted show that the achievement of mathematical connection ability for each indicator is still not achieved, so students' mathematical connection ability is still relatively low.
