Abstract

Differentiated learning emphasizes that teachers must pay attention to students' learning differences and initial abilities. It is not easy for educators to deliver lessons in classrooms where students have varying skill levels and learning styles. The use of Canva facilitates all learning styles, whether auditory, visual, or kinesthetic. The application helps students understand lessons because, in addition to text, it also includes animations, audio, images, graphics, and videos, which keep students focused during class. The aim of this research is to develop digital teaching materials based on differentiated learning using Canva for mathematics subjects. The type of research conducted is R&D development using the 4-D model, which includes 1) Define, 2) Design, 3) Develop, and 4) Disseminate. Based on the analysis, the material validator test scored 82.1%, categorized as highly valid. The media validator test scored 88%, also categorized as highly valid, making the average validation test results meet the validity criteria. Additionally, the student response questionnaire regarding the digital teaching materials showed 82.9% positive responses, categorized as practical, and the evaluation test results showed that 80,44 of students achieved mastery, categorized as effective. Therefore, the digital teaching materials based on differentiated learning assisted by Canva meet the criteria of being valid, practical, and effective.

Abstract

This qualitative descriptive study provides a comprehensive profile of scientific academic writing skills among university students enrolled in mathematics education and primary school teacher education programs. Using a self-assessment survey, 110 students evaluated their proficiency across various dimensions of scientific writing, including clarity and coherence, organization of scientific arguments, use of scientific terminology, citation and referencing, critical evaluation of literature, and independent thinking. The data were analyzed using descriptive statistics to identify trends, strengths, and areas for improvement in students' writing skills. The findings revealed that students generally feel confident in their ability to construct clear academic paragraphs and use appropriate vocabulary and tone, but struggle with higher-order writing tasks such as synthesizing information from multiple sources and organizing extended scientific texts. Many students also expressed difficulties in applying proper citation and referencing styles, particularly APA format. Key strengths identified in the study include competence in basic grammar, punctuation, and paragraph structure, while notable weaknesses were found in areas such as critical evaluation, organizing complex arguments, and correct application of citation conventions. These results suggest a need for targeted instructional interventions to help students develop the advanced scientific writing skills necessary for academic success. The study's findings contribute to the ongoing discourse on improving scientific academic writing pedagogy, offering insights for educators to better support students in mastering these critical skills.

Abstract

This study aims to analyze the mathematical concept understanding ability of seventh grade students at SMP Swasta Bhayangkari 3 Rantauprapat regarding the topic of two-dimensional quadrilaterals. The assessment of concept understanding focuses on determining the extent of students' abilities in solving problems related to mathematical concepts, using the following indicators: Understanding mathematical concepts includes the ability to define a concept both verbally and in writing, group objects based on certain properties, provide examples and counter-examples of a concept, present the concept in various forms of representation, and apply concepts or algorithms to solve problems. The research method used is descriptive qualitative, involving 24 students as research subjects. Data were collected through a concept understanding test consisting of 5 questions related to two-dimensional quadrilaterals. The results indicate that 8 students, or 33.3%, are categorized as having high understanding, 12 students, or 50%, are in the moderate category, and 4 students, or 16.6%, fall into the low category. Thus, the mathematical concept understanding ability of the students is considered to be quite good. The research results show that students' understanding of mathematical concepts still needs to be improved, especially in the ability to explain concepts, clarify the nature of objects, and present concepts in various representations.

Abstract

Pelajaran kimia memerlukan kemampuan daya ingat karena beberapa pelajaran kimia berkesinambungan satu dengan yang lain, meliputi ikatan kimia dan struktur atom. Kapasitas daya ingat sebagian siswa dinilai rendah dalam mengingat materi yang disampaikan, oleh karena itu perlu diketahui hubungan antara kemampuan daya ingat konsep struktur atom dengan hasil belajar siswa pada materi ikatan kimia. Lokasi penelitian di MAN 4 Kampar pada semester ganjil tahun ajaran 2023/2024. Metode penelitian yang digunakan adalah penelitian kuantitatif berupa penelitian korelasional. Sampel yang digunakan dalam penelitian ini terdiri dari siswa kelas X1 dan X2 di MAN 4 Kampar. Teknik pengambilan sampel menggunakan teknik purposive sampling. Teknik pengumpulan data untuk penelitian kemampuan daya ingat dan hasil belajar menggunakan tes berbasis soal, angket kemampuan daya ingat, dan dokumentasi. Sedangkan teknik analisis data menggunakan rumus korelasi momen Pearson. Hasil yang diperoleh dari pengumpulan data menunjukkan rhitung = 0,543 dengan nilai sig dua sisi sebesar 0,000, dan nilai rtabel pada taraf signifikansi 5% sebesar 0,316. Nilai signifikansi sebesar 0,000 < 0,05 dan nilai rhitung > nilai rtabel, maka dapat disimpulkan bahwa H0 ditolak dan Ha diterima yang berarti terdapat hubungan antara kemampuan menghafal konsep struktur atom dengan hasil belajar ikatan kimia.

Abstract

Quadrilateral is one of the geometry topics in the curriculum, and students at junior high school must understand the topic. Therefore, we researched 40 students (11/13 years) in Kambera District, East Sumba Regency, East Nusa Tenggara, to identify and describe students' geometric thinking levels. The research is descriptive qualitative research with data collection techniques and is a written test for the quadrilateral case. The data were analyzed using van Hiele's theory. The results showed that 1) only one-third of the students are at level 0 (visualization), i.e., students knew geometric pictures by observing the images or models. At this level, half of the students still need to improve in classifying the types of quadrilaterals, and 2) only a few students are at level 1. They can understand or know the properties of quadrilaterals. The written results found that almost all students needed help understanding the topic of quadrilaterals and their properties well. Nearly all students have yet to be able to recognize and classify the types of quadrilaterals well.

Abstract

In creating educational objectives aligned with the Learning Compass 2030, it is essential to establish a learning environment where students feel comfortable and to apply learning strategies suited to the characteristics of the learners. The objective of this research is to map students' metacognitive skills to understand their learning strategies in solving science-related problems. This study employs a mixed-methods approach, which involves collecting both quantitative and qualitative data, integrating the two forms of data, and using diverse research designs. The quantitative data were obtained from administering metacognitive skills tests and questionnaires, while qualitative data were gathered from student interviews. The research yielded several findings: (1) expert validity results for the metacognitive skills instrument indicated it is valid, (2) trial testing of the instrument showed it to be reliable and valid, (3) the profile of students' metacognitive skills across all indicators was found to be low in three different schools, and (4) there was a high response rate. The novelty of this research lies in mapping students' metacognitive skills in three different regions after the COVID-19 pandemic.
