The relationship of numeracy literacy skills to self efficacy in junior high school students

Renti Rengganis — 2024-03-30

This study aims to describe the relationship between numeracy literacy skills and self-efficacy of private junior high school students in Bandung City, namely SMP Muhammadiyah 6. This study uses multivariate correlation method with a sample of 10 students with random sampling technique. The instruments used in this research are numeracy literacy test and self-efficacy questionnaire. The data were processed by descriptive and inferential quantitative methods. The results showed that students' numeracy literacy skills from the test results and questionnaire results showed no influence between the two variables. The conclusion of this study is that students who have low or high numeracy literacy skills have no influence on self-efficacy, this is based on the results of student questionnaires.

Learning trajectory for teaching 3D shapes using PMRI approach with a mosque construction context

Rika Amelia — 2024-03-30

The background of this research is based on the importance of students' conceptual understanding of geometry in the context of mosque construction. The geometry of the space has an important role in creating a beautiful and meaningful mosque design. The aim of this research is to understand the extent to which the PMRI approach can be applied to spatial geometry in the context of mosque construction. This research uses a design research method with a PMRI (Indonesian Realistic Mathematics Education) approach for class VIII students at Ulul Albab Takokak Cianjur Integrated Qur'an Middle School with a focus on Geometry and Space Building material. Data collection was carried out by means of observation, interviews and documentation. The results of this research are that students can find out how the concept of building space can be applied to everyday life, especially in building mosques.

An Exploration of ethnomthematics in the Cibuntu Tofu industry

Fahril hakim — 2024-03-30

Ethnomatematics is a science that studies or unites culture with mathematics. Culture is a habit of the people that is often carried out every day and Mathematics has many benefits for human life, so without realizing it, many mathematical concepts are applied in everyday life. Like calculating sizes and drawing a plane shape, buying and selling transactions are related to integer operations. This is in line with the research conducted, namely studying and analyzing ethnomathematics exploration in making tofu in Cibuntu which is a daily livelihood in order to obtain basic information in developing ethnomathematics for learning mathematics in the field of geometry specifically on the shape and size of tofu and learning mathematics in the field of social arithmetic specifically in tofu price. The goal in making Ethnomathematics is to harmonize the culture of the Cibuntu residents into the concept of Mathematics. The method used in this study is the Exploration method, which is to search in depth about Cibuntu Tofu. The instruments used in this study were interviews and documentation.

Research on classroom teaching strategies for junior high school students under the guidance of core literacy

Yujiao Zhong — 2024-03-30

Student-oriented classroom is the fertile ground for students to develop core literacy of mathematics. The new curriculum standard emphasizes the teaching concept of "student-oriented". In the teaching activities, teachers should give full play to the subject status of students, return the classroom to students, so that students can better show themselves, so that they can master mathematical knowledge and develop the core literacy of mathematics subject naturally. However, at present, the classroom atmosphere of some middle school mathematics students' classroom reform pilot middle schools has not reached the ideal effect. There are some problems in the teaching classroom, such as ignoring students' main position, ignoring students' initiative in learning, and teachers' student-oriented concept is not thorough enough. This paper aims to develop students' core literacy. By studying the current situation of the mathematics students-based classroom in junior middle school and putting forward strategies to solve the problems, the teaching mode of the student-oriented classroom is improved.

Development of augmented reality learning media to improve mathematical problem-solving skills of 8th grade junior high school students

Sheila Zalzabilla Al-jabar — 2024-03-30

This research aims to develop learning media that can assist students in enhancing their mathematical problem-solving skills in 8th grade junior high school. This study utilizes a design research method with a development study approach conducted in two phases: initial design and formative evaluation, including self-evaluation, prototyping (expert review, one-to-one, and small groups), and field research conducted at SMP Negeri 7 Cimahi. The research subjects consist of 35 students from class VIII E of the junior high school. Data collection techniques used in this study include documentation, interviews, student response questionnaires, and tests. The research data are analyzed quantitatively and qualitatively. The data analysis results reveal that this study produces a logically reasoned mathematical thinking for Augmented Reality learning media on two-dimensional solid shapes that are valid, practical, and have potential effects. In this regard, the Augmented Reality learning media has valid and constructive content, as well as language validation from expert reviews. Conversely, the practicality of the Augmented Reality learning media has been achieved through revisions based on one-to-one feedback and small group discussions. Furthermore, the prototype of the Augmented Reality learning media has shown potential effects in enhancing students' mathematical problem-solving skills.
