Abstract

The Indonesian province of Medan is known for its unique culture, which includes architecture, linguistics, music, art, and traditional crafts. Each city has its own distinct identity, and Medan is one of them. The Negeri Medan Museum shares its history with us. This research focuses on introducing spatial structures through the contents of historical buildings, namely the State Museum in Medan. This research aims to describe flat shapes in mathematics learning. The research method used is ethnography, where researchers make observations through observation, documentation and literature studies related to the Medan State Museum. This type of research is qualitative which only describes how the contents of the Medan State Museum Since mathematics requires facts to be precise, understandable, and reliable. From the results of the exploration, it can be concluded that the Medan State Museum is related to the mathematics of geometric shapes consisting of circles, tubes, cubes and rectangles.

Abstract

Mathematics and culture are two things that cannot be separated because the application of mathematics is always applied in everyday life. Culture can be used as a source of learning for students in schools. Mathematics related to culture is called ethnomathematics. The Deli Serdang Museum, located on Jalan Petapahan, Lubuk Pakam District, Deli Serdang Regency, is one of the historical places in Deli Serdang. The purpose of this study is ethnomathematics. An ethnomathematics study at the Deli Serdang Museum was conducted. This study conducted qualitative research using an ethnographic approach. Data were collected directly by researchers through observation, interviews, documentation, and literature studies. Based on the research, researchers obtained several mathematical concepts, such as flat buildings and spaces at the Deli Serdang Museum. The results of the investigation at the Deli Serdang Museum showed that mathematical concepts include flat quadrilateral buildings, such as rectangles, squares, or trapezoids, as well as flat curved-sided buildings in the form of circles and cylinders. The results of the exploration of the Deli Serdang Museum showed mathematical concepts such as flat buildings and spatial buildings. Researchers discovered the concept of quadrilateral plane shapes, such as rectangles, squares, and trapezoids, as well as curved-sided plane shapes in the form of circles and cylinders.

Abstract

This study aims to determine whether there are differences in the results of the influence of the application of the Creative Problem Solving (CPS) model, the Problem Based Learning (PBL) model and the Direct Instruction (DI) model in improving mathematical creative thinking skills in the material of quadrilaterals and triangles of class VII students of SMPN 9 Kota Jambi. Using an experimental posttest only control research design, this study involved the population of all class VII students of SMPN 9 Kota Jambi in the 2023/2024 academic year totaling 204 students from 7 classes. Through the Random Sampling technique , three classes were selected as samples, namely VII A, VII B, and VII C. Data collection was carried out using two instruments: observation sheets for the implementation of learning and evaluation tests for mathematical creative thinking skills. To analyze the collected data, statistical analysis using One way Anova showed a significance value of 0.000 which was smaller than 0.005. These findings indicate different effects of the application of the three learning models - CPS, PBL, and DI - on improving mathematical creative thinking skills. Posttest data showed that the group of students who received learning with the CPS model achieved an average score of 16.94, while the PBL group obtained an average of 16.26. Both groups showed superior results compared to the group using the DI (Direct Instruction) learning model

Abstract

The purpose of this study was to test students' ability to solve mathematical problems using Pythagorean theorem material. The subjects of this study were grade VIII students of SMP Ani Idrus perguruan ERIA, a class consisting of twenty children selected using purposive sampling techniques, where six students were selected based on their ability to the instruments in this study, along with supporting instruments such as test instruments for students' mathematical problem-solving abilities and interview procedures. The findings showed that while students in the high-ability category were able to solve problems, they lacked comprehensiveness in reading questions. Advanced students cannot solve a given problem because they can only understand it. Students who are classified as poor in ability are no longer able to answer the challenges given because they continue to struggle to understand the questions given.

Abstract

The learning techniques applied during the independent curriculum era require learning innovations that will be applied in learning, one of which is by implementing the PBL learning model and also the Inquiry model, where the application usually uses the direct instruction model. This study explains how the influence of students' mathematical literacy skills with the material taught, namely algebraic forms, with the learning model applied in each predetermined experimental class. True Experimental Design is a learning method used by researchers, Pretest-Posttest Control Group Design is the data obtained used by researchers. The results of the study found that the application of the inquiry learning model tends to provide a greater tendency towards students ' mathematical literacy skills compared to PBL and direct learning. In accordance with the results of the one-way ANOVA test and Tukey's follow-up test. The significant results obtained from the similarity test showed an increase in students' mathematical literacy skills, namely 0.727> 0.05. The hypothesis was found  accepted, with the results of the difference in the average influence of students' mathematical literacy test scores on the application of PBL, inquiry, and direct instruction learning models.

Abstract

This study aims to describe students' metacognition in solving PtLSV problems regarding field-independent and field-dependent cognitive styles. This research was conducted at SMP Negeri 1 Muaro Jambi in the 2023/2024 academic year. This type of research is qualitative research. The subjects of this study were 4 students of class VIIA of SMP Negeri 1 Muaro Jambi, 2 students each with field-independent cognitive style and field-dependent cognitive style. Data collection methods were the results of the GEFT test to determine students with field-independent and field-dependent cognitive styles , PtLSV problem-solving questions, unstructured interviews and documentation. Data analysis techniques consisted of data collection, data reduction, data presentation and conclusion. The results showed that students with field-independent cognitive style met all indicators of metacognitive activity in problem-solving. However, students with field-dependent cognitive style did not meet the metacognitive evaluation indicators in re-checking the results, and errors were seen in operating PtLSV problem-solving. The second student with a field-dependent cognitive style, he only met the metacognitive activity indicators in understanding problems but did not yet have a strategy in solving PtLSV problem-solving questions.

Abstract

This study aims to determine whether there is a relationship between the level of mathematical anxiety and student learning outcomes. This study uses a quantitative approach using a correlation test . The population consists of fifth-grade students at SD 2 Panjang, Kudus Regency, with a total of 11 students selected using a saturated sampling technique . Data collection techniques are carried out through questionnaires and tests. Data analysis is carried out by applying three statistical methods, namely the normality test, linearity test, and correlation test. The results of the correlation test show that H 0 is accepted with a correlation coefficient of -0.475, so it can be concluded that there is moderate negative relationship between the level of mathematical anxiety and students' mathematics learning outcomes. The higher the level of mathematical anxiety felt by students, the lower the mathematics learning outcomes they obtain. Conversely, the lower the level of mathematical anxiety, the higher the students' mathematics learning outcomes.
