Abstract

Siswa mengalami kesulitan dalam mempelajari materi mengurutkan pecahan. Salah satu faktor penyebab kesulitan tersebut adalah kurang lengkapnya buku teks matematika dalam menyajikan materi tersebut. Penelitian ini bertujuan untuk menganalisis sajian materi mengurutkan pecahan pada buku teks matematika kelas IV yang berfokus pada bentuk teori dan teknologinya. Jenis penelitian yang digunakan yaitu deskriptif kualitatif. Metode pengumpulan data yang akan digunakan adalah wawancara dan studi dokumentasi. Analisis data pada penelitian ini meliputi penyandian, pengkategorian, pembandingan, dan pembahasan. Hasil analisis menunjukkan bahwa sajian materi mengurutkan pecahan pada buku teks tersebut sudah lengkap. Akan tetapi ada beberapa perbaikan sajian materi yang direkomendasikan di antaranya direkomendasikan untuk menyajikan uji kemampuan prasyarat, direkomendasikan untuk menyajikan bentuk-bentuk pecahan serta menggambarkan bentuk pecahan dalam bentuk konkrit. Direkomensaikan untuk menyajikan cara menyamakan penyebut dengan KPK. Dengan demikian, sajian materi mengurutkan pecahan pada buku teks yang lengkap akan memudahkan siswa dalam memahami dan menguasai materi tersebut.

Abstract

This study aims to develop and test the feasibility and practicality of interactive mathematics learning media based on Canva on the topic of characteristics of flat shapes, grounded in Bruner's learning theory for elementary school students. The study used a Research and Development (R&D) method with the ADDIE model, which includes the stages of Analysis, Design, Development, Implementation, and Evaluation. The research subjects were 28 fourth-grade students of SD Negeri 9 Nagrikaler in a limited trial. Data were collected through expert validation sheets and student response questionnaires. The validation results showed a percentage of 92.4% from media experts and 95.1% from material experts, with an average of 93.75% (very valid). The practicality test obtained percentages of 79.26% for the media aspect, 80.81% for the material aspect, and 83.63% for the usefulness aspect, with an average of 81.18% (very practical). Based on these results, the Canva-based interactive mathematics learning media developed is deemed feasible and practical to use in teaching the characteristics of flat shapes in elementary schools. This media is able to support active, contextual learning and is in line with students' thinking characteristics through the application of enactive, iconic, and symbolic stages in Bruner's theory.

Abstract

This research is motivated by the need for interactive learning media to help elementary school students understand geometry of three-dimensional shapes, particularly in constructing and deconstructing cubes and rectangular prisms, which are abstract in nature. This study aims to examine the feasibility of mathematics learning media on three-dimensional geometry materials through validation by media experts and subject-matter experts, as well as to test the practicality of the CUBYLAND media through student response questionnaires. The research method used is Research and Development (R&D) with the ADDIE model, which includes the stages of analysis, design, development, implementation, and evaluation. The research subjects consisted of 22 sixth-grade elementary school students. Data were collected through subject-matter expert validation sheets, media expert validation sheets, and student response questionnaires. The validation results showed that the learning media obtained a feasibility percentage of 95.96% from subject-matter experts and 90.90% from media experts, with an average of 93.43%, which falls into the “very feasible” category. The implementation results indicated that students gave positive responses to the aspects of visual appearance, ease of use, and engagement in learning. Based on the evaluation results, Canva-based learning media using the Van Hiele theory approach are declared feasible and practical to be used as an alternative mathematics learning media in elementary schools.

Abstract

This study aims to examine the feasibility and practicality of the Ca-Badar (Canva Plane Figures) learning media on plane geometry material for fourth-grade elementary school students. The feasibility of the media was evaluated based on assessments from media experts and subject matter experts, while its practicality was examined based on students’ responses. The Ca-Badar media was developed by integrating the principles of Bruner’s Theory, which include the enactive, iconic, and symbolic stages. The development process employed the ADDIE model, consisting of the analysis, design, development, implementation, and evaluation stages. The Ca-Badar media contains plane geometry materials, activities for matching the characteristics of plane figures, educational videos, interactive quizzes, and a creative project in the form of constructing a house using plane figures by utilizing Canva elements. The validation results from media experts and subject matter experts indicate that the Ca-Badar media falls into the highly valid and feasible category, with an average assessment score of 94.16%. The implementation of the media with 28 fourth-grade students at SDN 5 Sindangkasih shows that Ca-Badar is practical to use through laptops and projectors and is able to encourage student engagement and understanding during the learning process. In addition, the subject matter expert assessment resulted in an average score of 81%, which confirms the feasibility of the media as a learning tool for mathematics in elementary schools. The impact of this study is the availability of a feasible and practical digital learning media that can be used by teachers as an alternative for presenting plane geometry material, as well as a reference for the development of innovative Canva-based learning media in elementary schools.
