Abstract

Yogyakarta has a nickname as the City of Culture. Yogyakarta has several cultures that are closely related to the context of learning mathematics. However, not many educators in Yogyakarta see this culture as a context that can be a starting point in learning mathematics. Thus, this study aims to explore the culture of Yogyakarta's people that can be used as a context in learning mathematics. This study uses ethnographic studies sourced from literature studies, field observations, and interviews with informants who understand the ancient Javanese language well to clarify and / or provide more understanding of the results of the literature review collected. The results showed some mathematical languages used by the Yogyakarta people in Javanese that could be used as starting points in learning mathematics. This mathematical language includes the mention of numbers, area, angle, volume, indefinite units, and determination of time units.

Abstract

As part of 21st-century skills, communication is an essential skill for students. Students 'mathematical communication tends to below, one of which is influenced by students' self-confidence. For this reason, the purpose of this study is to describe the mathematical communication skills in solving circle problems based on students' self-confidence. Determining the subject using purposive sampling technique, namely from 36 students of class VIII SMP in Madiun, East Java, Indonesia, obtained two subjects with high self-confidence (SCT) and one subject with low self-confidence (SCR). A qualitative descriptive approach was used in this study. Tests and interviews were used as data collection techniques. Data were analyzed through reduction, presentation, and concluding. The results of this study include: SCT is capable while SCR is less able to meet the indicators of mathematical communication skills both in writing and orally at the stages of understanding problems, implementing plans, and checking back; and SCT can meet mathematical communication indicators both written and oral, while SCR is less able to meet written mathematical communication indicators but can verbally at the stage of planning completion. The level of self-confidence of students differentiates their mathematical communication skills in solving problems. Thus, a teacher needs to design an appropriate question to train students' mathematical communication skills with low self-confidence.

Abstract

This research is motivated by the importance of students 'mathematical understanding, but the fact is that students' mathematical understanding is still low in working on algebraic form questions. This problem brings out a learning obstacle, where students cannot interpret the algebraic form elements and cannot operate the algebraic form. This study aimed to design a didactic design phase using fables based on students' mathematical understanding. The research method is descriptive qualitative research. Design is Didactical Design Research (DDR) with 15 junior high school students as subjects. The data was collected using triangulation techniques, then analyzed descriptively. This study results in a didactic design in the form of a situation that can anticipate students' learning obstacles in algebraic form material and facilitate students' thinking process. Situations are created using exciting pictures and stories to motivate student learning. The results show that the situations that have been created make it easier for students to group similar and dissimilar terms and can operate the algebraic form easily and algorithmically. The students also can interpret the elements of the algebraic form along with addition and subtraction operations in the algebraic form based on the understanding of each student.

Abstract

This study aims to develop a mathematics test with the COVID-19 context to measure the student's skill competencies in grade VIII SMP/MTs. This study was a research development by following the test development procedures: compiling blueprints, writing items, reviewing questions, testing, analyzing the results of trials, and revising. The developed test consists of multiple-choice items with four options. These items were validated content by three experts (teacher, lecturer, and mathematics trainer) and were tested to 86 students. This study developed a mathematics test set with the COVID-19 context consisting of ten items that experts declared valid. Trial of ten items showed two items (numbers 7 and 6), which were not good. Item number 7 was too easy, while item number 6 was not good in the discrimination index. Besides, the two distractors in item number 7 did not work correctly. The estimated coefficient of reliability of the measurement results was quite high, indicated by a coefficient value of 0.658. The items that were not good have been revised by modifying the items so that the index of difficulty and discrimination look good. Useful and revised items were assembled into a mathematics test set for grade VIII students.

Abstract

The national exam results show that students still have difficulty solving PISA standardization questions, reinforcing the reason why Indonesian students' mathematical literacy scores on PISA are still very low. This mathematical literacy is part of the mathematical thinking ability, so building it will impact students' mathematical literacy. The comprehensive mathematics instruction (CMI) model is thought to build students' mathematical thinking abilities. This study aims to describe students' mathematical thinking achievement who obtain learning with the CMI model. Besides, this study also analyzed the achievement of students' mathematical thinking through the CMI model by paying attention to the prior knowledge of mathematics (PAM). This research is a quasi-experimental study. Samples were taken purposively from the population of high school students in Subang. The results showed that the achievement of students' mathematical thinking through the CMI model differed significantly from students' mathematical thinking abilities through conventional models. The difference in the achievement of generalizing, conjecturing, and convincing abilities between students who get CMI model learning and those who get conventional model learning occurs in students with moderate PAM. Thus, the CMI model is effective for building students' mathematical thinking abilities.
