Abstract

Due to the Covid-19 pandemic, face-to-face instruction in the field of education has been replaced by online learning. As a result, to meet the learning goals, teachers must be innovative and creative while delivering online learning. Student Achievement with Edmodo is one alternate online learning choice. This analysis aims to explain the effects of the introduction of Edmodo-supported Student Achievement, as well as student reactions to this learning, and to provide a single learning method that is successful and can aid teaching and learning experiences for high school mathematics content during the Covid-19 pandemic. This study employs qualitative analysis approaches. The subjects of this research were five students from Tasikmalaya City's State Senior High School. Based on the outcomes of a few experiments, it was determined that the learning experience was enjoyable and aided students' comprehension of the Trigonometry content. Students are pleased with the learning experience provided, and they believe they have made improvements as a result of their participation in the learning. According to the effects of the impact size estimation, the implementation of the Student Achievement learning model is very accurate. Then, for general student assessment, Student Achievement learning with Edmodo is beneficial to introduce in the middle of the Covid-19 pandemic, so that it can be used as a substitute in online learning.

Abstract

The evaluation of the Independent Curriculum (Kurikulum Merdeka) is currently underway, employing various methods such as the Minimum Competency Assessment (Asesmen Kompetensi Minimum [AKM]). AKM assesses general yet fundamental competencies, including numeracy skills. This assessment method endeavors to delineate students' numeracy skills within the context of website-based learning. Employing a descriptive qualitative method, the study involves 20 eighth-grade students from a Junior High School in Ciamis, West Java, Indonesia. Students are instructed to access a website developed by the researchers, featuring study materials and example problems. Throughout the learning activities, students utilize the Google Meet video conferencing application, activating their cameras for interactive sessions. Following the lesson, students undergo a numeracy skills test comprising validated questions. The research outcomes unveil three distinct levels of numeracy skills among students: high, medium, and low. Those with high-level numeracy skills demonstrate proficiency in mathematical numeracy skills indicators but exhibit errors in applying formulas. Conversely, students with moderate and low mathematical numeracy skills commonly struggle with concept comprehension, identifying relevant formulas, and making calculation errors.

Abstract

Computational thinking is a theory born in computer science that applies computational principles to solve a problem. It is a new concern in the PISA 2021 mathematical assessment to accommodate human resources needs that can compete in the 21st-century digitalization era. This study aims to develop a learning tool called student worksheet (LKPD) that integrates indicators of computational thinking skills into the material ratio. The method used is Research and Development (R&D), with the subject of research being 32 students in one Junior High School in Ciamis Regency. The data collection technique is done by observation, interview, and questionnaire given to material experts, media experts, and students. The data were analyzed quantitatively using descriptive product validity and practicality scores. The results showed that the assessment of material experts, including aspects of legality and morality, the feasibility of content, the feasibility of presentation, and aspects of computational thinking, received a level of validity of 99%, so it is included in the category of very valid. Likewise, the assessment of media experts covering anatomy, graphics, and use of language was declared very valid, with a validity rate of 82 %. The product's practicality gets a very practical category with an average score of 86% covering material aspects, use of language, interest, and aspects of computational thinking. The products that have been developed are considered valid and practical for use as educational resources for learning ratios and enhancing computational thinking ability.

Abstract

Penelitian ini menjawab tantangan pedagogis dalam mengimplementasikan pembelajaran berdiferensiasi dan meningkatkan kemampuan numerasi dalam pembelajaran matematika berbasis teknologi. Secara khusus, penelitian ini bertujuan untuk merancang dan memvalidasi media pembelajaran digital interaktif menggunakan Articulate Storyline pada materi perbandingan dan proporsi untuk siswa Sekolah Menengah Pertama (SMP). Menggunakan metode Research and Development (R&D) dengan model 4D (Define, Design, Develop, dan Disseminate), media yang dikembangkan mengintegrasikan navigasi berbasis avatar, kustomisasi gaya belajar, serta tugas numerasi kontekstual yang relevan dengan situasi dunia nyata. Validitas media dinilai oleh ahli materi dan ahli media, sementara kepraktisannya dievaluasi melibatkan 39 siswa melalui uji coba skala kecil dan besar. Hasil penelitian menunjukkan tingkat validitas yang sangat tinggi, dengan skor 99% untuk kelayakan isi dan 82% untuk kelayakan media. Lebih lanjut, uji kepraktisan menunjukkan respons siswa yang positif, dengan skor rata-rata 86% pada uji coba skala kecil dan 81% pada uji coba skala besar. Temuan ini mengonfirmasi bahwa media berbasis Articulate Storyline ini valid secara pedagogis dan praktis untuk mendukung pembelajaran numerasi yang terpersonalisasi. Studi ini berkontribusi pada pengembangan literatur mengenai media instruksional adaptif dan merekomendasikan penerapannya secara lebih luas untuk memfasilitasi strategi pembelajaran berdiferensiasi. This study addresses the pedagogical challenges of implementing differentiated instruction and fostering numeracy skills in technology-enhanced mathematics classrooms. Specifically, it aims to design and validate interactive digital learning media using Articulate Storyline focused on ratio and proportion for junior high school students. Employing a Research and Development (R&D) approach with the 4D model (Define, Design, Develop, and Disseminate), the developed media integrates avatar-based navigation, learning style customization, and contextual numeracy tasks aligned with real-world situations. The validity of the media was assessed by subject matter and media experts, while its practicality was evaluated involving 39 students through small- and large-scale trials. The results demonstrated a high level of validity, with scores of 99% for content feasibility and 82% for media design. Furthermore, practicality tests revealed positive student engagement, yielding average scores of 86% in small-scale trials and 81% in large-scale trials. These findings confirm that the Articulate Storyline-based media is pedagogically valid and practical for supporting personalized numeracy learning. This study contributes to the literature on adaptive instructional media, suggesting its potential for broader implementation to facilitate differentiated learning strategies.

Abstract

Geometry learning, particularly plane geometry topics at the elementary school level, still faces various challenges, especially related to students’ understanding of abstract concepts and low learning motivation. Conventional instructional media that rely mainly on textbooks and verbal explanations are often insufficient to accommodate the learning characteristics of elementary school students who require concrete visualization and direct interaction. This study aims to examine students’ responses to the use of Heyzine flipbook-based interactive media in plane geometry learning at the elementary school level. This study employed a descriptive survey design involving a single class of second-grade elementary school students to evaluate students’ responses toward the implementation of Heyzine-based interactive media in plane geometry learning.The research instrument was a student response questionnaire covering aspects of presentation, content, and language. Data were analyzed using descriptive percentage techniques. The results showed that the Heyzine-based interactive media obtained a feasibility percentage of 93.33%, which was categorized as very feasible. Overall, these findings indicate that Heyzine flipbook-based interactive media can effectively support plane geometry learning and enhance students’ interest and conceptual understanding, future studies are recommended to investigate the effectiveness of Heyzine-based media on students’ learning outcomes through experimental research designs involving larger samples and different educational levels.
