Abstract

Mathematics is a basic science that is widely used in various aspects of life. However, in learning mathematics in schools there are still many students who have difficulty learning mathematics. The purpose of this study is to (1) describe the difficulties experienced by students in solving math problems in the composition function material for class X MA Al-Muayyad Surakarta (2) to describe the factors causing difficulties in learning mathematics in the composition function material for class X MA Al-Muayyad Surakarta. . The subjects of this study were determined by purposive sampling technique, namely 3 students of class X IPS MA Al-Muayyad Surakarta with high mathematical abilities. This research is a descriptive qualitative research with data collection techniques based on the method of tests, interviews, and documentation. Data validation was carried out by time triangulation, namely by comparing the first and second test data. The data analysis technique used is data reduction, data presentation, and conclusion. The results of the study show that the difficulties felt by students in solving composition function questions include, (1) Difficulty carrying out problem solving and (2) Difficulty checking again. Factors that cause students' learning difficulties are internal factors consisting of: (1) lack of understanding of the material, (2) lack of accuracy in doing (3) lack of accuracy in counting (4) students feel confident in their answers, and (5) students forget and don't used to rechecking. Meanwhile, the external factor causing the difficulty is the non-conducive environment that affects the students' concentration.

Abstract

This study aims to describe students' difficulties in solving word problems on arithmetic sequences and series material with problem solving steps according to the Polya indicator, which consists of understanding the problem, planning a solution, solving the problem, and re-examining. The method used is descriptive qualitative research, with class X subjects totaling 35 students at SMA Negeri 1 Nguter for the 2022/2023 academic year. The research data collection technique is by giving a test in the form of story questions totaling 3 questions, with predetermined indicators. While interviews are used to check the validity of the data and continue the discussion to achieve research objectives. This study concluded that: 1) students are not used to solving word problems, 2) students tend to work on questions without going through the Polya problem solving steps, 3) students are used to working on convergent questions, and 4) errors occur in solving problems caused by students forgot the formulas on arithmetic sequences and series material. Abstrak Penelitian ini bertujuan untuk mendiskripsikan kesulitan siswa dalam menyelesaikan soal cerita pada materi barisan dan deret aritmetika dengan langkah pemecahan masalah menurut indikator Polya, yang terdiri dari memahami masalah, merencanakan penyelesaian, menyelesaikan masalah, serta memeriksa kembali.

Abstract

One of the effective strategies to measure students' mathematical literacy is the mind mapping approach to education. The purpose of this study was to describe the mind mapping model on flat building materials in improving students' mathematical literacy. The approach method used was descriptive qualitative, this study surveyed 21 sixth grade students of SMP Penda Tawangmangu, with three samples selected to reflect high, medium, and poor performance. The strategies used were interviews and test questions. Data analysis procedures included data collection, data reduction, data presentation and conclusions. Three indicators were met by four students in the high mathematical literacy ability category, thirteen by students in the medium mathematical literacy ability category, although the level of completeness and accuracy was lower, and four by students in the low mathematical literacy ability category.

Abstract

Overall, this study aims to assess college students' field-dependent metacognitive skills in mathematics problem-solving. We administered the Group Embedded Figures and Mathematical Ability Tests to 35 future educators from a private school in Sukoharjo, Indonesia. Students' questioning of each group served to gauge their proficiency in solving problems, as shown in the results. Participants also demonstrated partially achieved metacognitive abilities, as measured by the (metacognitive) skills criterion, which encompassed tasks such as planning, monitoring, assessing, and predicting. First, the participants documented and explained the facts given in the question. Second, they checked the results against the plan. Third, they evaluated the success of the objectives by analyzing the results to make sure everything went according to plan. Finally, they predicted and stated the results of the problem-solving process. In light of these findings, researchers and teachers facing comparable obstacles would do well to delve deeper into the function of metacognitive abilities in problem-solving.

Abstract

The goal of this community dedication program is to enhance the quality of scientific articles written in SD N.2 Bangsri Purwantoro Wonogiri, with the aim of publishing them in the indexed journal Sinta. The main problems faced were the lack of knowledge of teachers about the quality of scientific articles, the importance of scientific work in IPTEK's growth, and the significance of the author's reputation in indexed journals. The dedication methods used include training, workshops, seminars, and mentoring. Training and workshops are held on a regular basis with the involvement of experts and practitioners of scientific writing. Seminars and discussions feature relevant case studies to enhance the understanding of participants. Program performance evaluation is carried out through periodic monitoring, qualitative and quantitative assessments, as well as results analysis. Program sustainability strategies include sustainable capacity development, mentoring and support, collaboration and networking, and program evaluation and adaptation. The results of this program showed an improvement in the knowledge and skills of teachers in writing scientific articles, as well as an increase in the number of articles submitted and received by Sinta-indexed journals. In conclusion, the program has improved the quality of writing scientific articles in SD N.2 Bangsri Purwantoro Wonogiri and has made a positive contribution to the development of IPTEK in the school environment. Thus, the program is expected to be a model for other schools in improving the quality of scientific articles and publications in indexed journals.
