Abstract

The limited usage and repurposing of media in education served as the driving force behind this study. Student Textbooks and Student Worksheets (LKPD) are designed to support instruction. Additionally, Systems of Two Variable Linear Equations (SPLDV) implicit graphical problem solutions are made possible with the use of GeoGebra media. In this inquiry, interactive learning tools for the SPLDV curriculum will be made using GeoGebra. The 4-D Thiagaradjan model serves as a model in this study on development. Define, design, develop, and deploy are the four stages. This experiment involved eighth-graders aged 14 and two eighth-grade math teachers. Utilizing a requirements analysis, interviews, and questionnaires, observational data was gathered. An study of the data collection process's demands, as well as interviews and surveys, are all included. Validity, practicability, and efficacy were three essential development conditions that had to be met before a study could be put into action. Proportion scores were validated by two qualified validators to support the study's conclusions. For learning device formats, graphics, language, and content validation, the average score is 3.78. (Applicable classifications). The effective category, which received an average score of 74.3 on the pretest and 87 on the posttest, the complete category, which served as a gauge of the teacher's capacity to manage learning and received an average score of 4.4 in the very good category, and the practical category, which also received an average score of 4.4 in the very good category, served as the foundation for the research findings.

Abstract

Determinants are conventionally defined only for square matrices, which leaves the theoretical discussion of rectangular matrices relatively undeveloped. This study aims to extend determinant theory by introducing a generalized form of the cofactor expansion applicable to non-square matrices. The method employed in this research is a theoretical–analytical approach that begins with identifying fundamental determinant axioms and proceeds with the construction of a recursive cofactor expansion for   matrices with . Worked examples are used to demonstrate the linearity, antisymmetry under row interchange, and reduction consistency of the proposed formulation when applied to square matrices. The findings indicate that the generalized expansion preserves essential algebraic properties and shows compatibility with established rectangular determinant definitions, including the Radić determinant. Overall, this study provides a coherent theoretical foundation for the generalized determinant of rectangular matrices and contributes to broader applications of determinant-based analysis in linear algebra

Abstract

The implementation of the Kurikulum Merdeka in elementary schools requires teachers to have innovation and adaptation competencies, particularly in social studies learning. It emphasizes student-centered learning and allows teachers the freedom to choose learning methods and media. However, during its implementation, teachers face various challenges that need to be identified in order to improve the quality of learning. This study aims to describe the problems faced by teachers in implementing the Kurikulum Merdeka in social studies learning and examine the role of supervision at Gugus Dua Bintang Bayu Elementary School. The method used is a descriptive qualitative approach, with data collected through interviews, observations, questionnaires, and documentation involving teachers and the principal. The results indicate that the main challenges for teachers include low competency in learning innovation, limited understanding of the curriculum, lack of technology as a learning medium, difficulties in developing learning tools such as lesson plans and modules, and inadequate facilities and learning resources. Existing supervision is more administrative in nature and lacks ongoing practical guidance. These findings emphasize the importance of increasing teacher capacity and strengthening supervision for effective implementation of the Kurikulum Merdeka.   Abstrak Penerapan Kurikulum Merdeka di sekolah dasar yang menuntut guru memiliki kompetensi inovasi dan adaptasi, khususnya dalam pembelajaran IPS menekankan pembelajaran berpusat pada murid dan memberi kebebasan pada guru dalam memilih metode dan media pembelajaran. Namun, pada pelaksanaannya guru dihadapi dengan berbagai tantangan yang perlu diidentifikasi untuk meningkatkan kualitas pembelajaran.
