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

This study was conducted to address the issue of students' low comprehension of mathematical concepts. Learning videos were explored as a potential instructional medium to improve this comprehension. The purpose of the research was to examine the effectiveness of learning videos on the comprehension of mathematical concepts among grade XI students at SMA Negeri 3 Sukoharjo. A quantitative research method was employed using a true experimental design with a pretest-posttest control group. The sample consisted of 66 students from classes XI F.5A and XI F.5B, selected through a cluster random sampling technique. Data were collected through a test assessing students' comprehension of mathematical concepts. Prerequisite tests, including normality and homogeneity tests, were conducted prior to hypothesis testing, which was carried out using the t-test. The results indicated that learning videos effectively improved students' comprehension of mathematical concepts. This conclusion was supported by the t-test results, where tcount (2.1085) exceeded ttable (1.669), leading to the rejection of H0 and acceptance of H1​. Furthermore, the experimental group showed a significant increase in average scores after the intervention with learning videos, with the pretest average of 76.24 rising to a posttest average of 87.91. Based on these findings, it can be concluded that learning videos are an effective instructional medium for enhancing the comprehension of mathematical concepts among grade XI students at SMA Negeri 3 Sukoharjo in the 2023/2024 academic year.

Abstract

This study explores ethnomathematical elements in the architecture of the Sheikh Zayed Grand Mosque in Surakarta as a representation of mathematics in Islamic culture. The method used is qualitative with an ethnographic approach through observation, interviews, and documentation. The results show that the mosque's architecture contains mathematical concepts, such as geometry in the form of cubes, hemispheres, and triangular pyramids, symmetry in wall and floor ornaments, and translation in decorative motifs. These findings indicate that the mosque is not only aesthetically and religiously valuable but also contains mathematical concepts that can be a source of learning. This study concludes that the Sheikh Zayed Grand Mosque can be an interesting medium for ethnomathematics learning, connecting mathematics with Islamic culture, and enriching ethnomathematics studies in Indonesia.

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 Introduction : Ngargorejo Village, Ngemplak District, Boyolali Regency, the place where the Cengklik Reservoir is located. These reservoirs are the main source of livelihood (fishermen, karamba farmers, tour boat captains, and traders). Based on the SWOT analysis, the condition of Pokdarwis partners has environmental issues related to the very rapid growth of water hyacinths that disrupt the natural ecosystem. The work program appointed is EGO-PURL (Environmental Friendly Fertilizer Water Hyacinth) Fertilizer Manufacturing Training. Objective : Increase the empowerment and knowledge of water hyacinth utilization training participants into, EGO-PURL Compost. Method: This activity involved the Target Partner of Pokdarwis "Kartika" and the Ngargorejo Village Government Partner with, a total of 22 members involved. The activity will be held in July 2025. The activity method uses metacognitive methods which are outlined in the form of lectures, collaborative discussions, and practice. Evaluation was carried out using pretest and pos-tes assessments.  Results: EGO-PALL Fertilizer Making Training, obtained pretest scores to pos-tes which increased by 18 org (81.8%). Where the Mean Pre-test value = 74.6 and the Mean Pos-tes = 95. Conclusion: The results of the evaluation assessment show that there is an increase in knowledge from pre-test scores to pos-tes.  Suggestion: this activity can be developed into an MSME business for the women of the pokdarwis group.       Keywords: Advocacy; EGO-PALL Fertilizer Training; Metacognitive

Abstract

This study aims to determine whether the use of Swishmax software through the Culturally Responsive Teaching (CRT) approach has an effect on students' interest in learning mathematics. This study uses an experimental method in a quantitative approach. The population in this study was grade XI students, with samples selected using the random sampling method. Data collection was carried out through questionnaires and documentation. Data analysis techniques include calculating the average score, standard deviation, normality test, homogeneity test, and hypothesis test. The analysis prerequisite test was carried out through the Liliefors normality test, then continued with the F homogeneity test. For hypothesis analysis, the t-test (Independent t-Test) was used through a significance level of 5%. The results of the study show that if the t-count value is 2.62019, the t-table value at a significance level of 5% at df = 62 is 1.6698. From these data, t_count> t_table was obtained so that it can be concluded that there is an impact of using Swishmax Software through the Culturally Responsive Teaching (CRT) approach on students' interest in learning Mathematics.

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.
