Abstract

In the present digital age, the utilization of e-learning platforms in education is becoming increasingly significant. This is especially true in the field of Mathematics Education, where there exists a challenge to enhance students' critical and creative thinking abilities. This research aimed to investigate the improvement in students' critical and creative mathematical thinking abilities through the implementation of a team project-based model, Flip-a-Team, within UNP's e-learning platform. A quasi-experimental research design was used, applying a post-test control group approach. The sample involved 64 students from a mathematics study program who were enrolled in the July - December 2022 semester. These students were divided into two groups: 32 students in the experimental group (Class A) that was instructed through the Flip-a-team model, and 32 students in the control group (Class B) that experienced problem-based learning. Based on an independent t-test, the results demonstrated that the mathematical learning process incorporating the Flip-a-Team model had a positive and significant impact on the students' critical and creative mathematical thinking abilities. The Flip-a-Team model is recommended for implementation in mathematics instruction. The UNP e-learning platform could serve as a feasible solution for digitally based mathematics education, particularly in fostering students' critical and creative thinking abilities in mathematics.

Abstract

The low ability of students to understand and transform the concept of reflection to solve everyday problems is the main problem with learning mathematics because the implementation of learning mathematics is mechanical. Mathematics is taught by conveying formulas practically without linking them to students' daily activities. For this reason, this study aims to design a reflection learning trajectory in the context of the Lipa Sabbe Bunga Caramming motif as a starting point in learning to help students understand reflection material for solving everyday problems. The method used in this study is design research, which consists of three stages: preliminary design, design trials, and retrospective analysis. The subjects of this study were 23 students in class VIII-A of SMP Negeri 1 Tanasitolo. The instruments used in this study were student activity sheets (LAS), learning achievement tests, and interview guidelines. Student activity data during learning were analyzed retrospectively, and learning outcomes data were analyzed descriptively. The results of this study found that the learning trajectory of transformation geometry using the context of the lipa sabbe bunga caramming motif has four learning stages: (1) informal; (2) modes of; (3) modes of; and (4) formal. The learning stages can easily increase students' understanding of the concept of reflection. In the learning process, mathematical concepts are connected with daily habits, so students are enthusiastic and active in the learning process. This learning trajectory can assist teachers in optimizing learning so that students can easily understand the concept of reflection, equip them with critical thinking skills, and shape their character (cooperation, empathy, respect for others, awareness of social problems, a social spirit, and responsibility).

Abstract

This study aims to improve mathematics learning outcomes, especially in learning fractional arithmetic operations in fifth grade students of SD Muhammadiyah 01 Paron, Ngawi Regency. In this study, offline and online learning models or what is often called Blended Learning will be implemented using case study problems. This type of research is descriptive qualitative research, the research subjects are students of class Va and class Vb Muhammadiyah Elementary School 01 Paron, totaling 19 students in class Va and 20 students from class Vb, homeroom teachers of class Va and Vb and the principal of SD Muhammadiyah 01 Paron. The object of the research is the learning outcomes of fifth grade elementary school students, especially in mathematics subjects on the material of arithmetic operations on fractions using blended learning model learning. To test the validity of the instrument in this study using data triangulation. The research data were obtained from observations, interviews and learning outcomes tests. The data obtained were analyzed descriptively quantitatively and descriptively qualitatively. The results show that the average learning outcomes of mathematics using online learning models are still not effective because many students are constrained about mathematical concepts and students' understanding of fractional numbers is still low. With this, blended learning is a learning solution for elementary school students to improve learning outcomes and improve mathematical concepts. The average mathematics learning outcomes of students who are taught using a digital-based blended learning model are 70 while the average value of students who are taught using a conventional model is 57.5, it appears that the overall implementation of the learning process in the experimental class using a digital-based blended learning model is more supportive in mastering the material than in the classroom. control using conventional learning models.

Abstract

The ability of mathematical representation helps students solve mathematical problems in forms that are easy to understand and more concrete, so that they can maximize their potential for achievement in learning mathematics. The purpose of this study was to describe the mathematical representation abilities of junior high school students on the concept of congruence in terms of learning styles. The subjects of this study were 35 grade VIII junior high school students using a random sampling technique. Data collection was carried out using mathematical representation ability tests, learning style questionnaires, and interviews. After that, it was analyzed using triangulation techniques to determine the validity of the data. The results showed that on average, students have very good visual representation abilities with auditory, visual, and kinesthetic learning styles because all students can solve questions correctly according to the indicators. Students who have the ability to represent good expressions or equations have a visual learning style. Whereas students with word representation abilities cannot be said to be good because of the existing subjects, there are no students with any learning style who can solve word representation ability questions correctly. Based on this, it can be concluded that the low representation ability of students is not influenced by their learning styles, both visual, auditory, and kinesthetic, especially in the concept of congruence.
