Vietnamese sixth graders' mathematical communication competency developed by teaching fraction topics using the 5E model.

The 5E, an exploratory instructional model with growing popularity in current learner-centered educational practices, aims to develop learners' competencies. The study aims to evaluate the effectiveness of teaching fractions using the 5E instructional model to develop students' mathematical communication competency (MCC). The researchers used mixed methods with data triangulation in a 38-student experiment group (EG) who learned with the 5E model and a 41-student control group (CG) using traditional learning approaches to clarify the impact of the 5E model on the development of MCC, academic performance and learning attitude among learners.

The application of blended learning in mathematics teacher education: Protocol for a systematic review.

Introduction: In recent decades, especially in higher education, blended learning has become the most commonly used active teaching strategy. Because of the COVID-19 pandemic, blended learning, which combines face-to-face and online components, is believed to overcome the shortcomings of conventional teaching methods, particularly in face-to-face interactions. Based on PRISMA guidelines, this study follows the protocol for a systematic review of blended learning applications in mathematics teacher education.

The effectiveness of blended learning on students' academic achievement, self-study skills and learning attitudes: A quasi-experiment study in teaching the conventions for coordinates in the plane.

Individuals attempting to study remotely during the COVID-19 lockdown will find that blended learning is a helpful solution and results in a significant increase in learning engagement. The best benefits for teachers and students are obtained by maximizing the advantages of each teaching method and by combining the advantages of online and face-to-face instruction. The study aims to investigate the effectiveness of the flex model of blended learning in teaching the mathematics subtopic of coordinates in the plane through the improvement of students' academic achievement, self-study skills and learning attitudes.

The improvement of 10 students' mathematical communication skills through learning ellipse topics.

Mathematical education in general, and mathematics education at high schools in particular, creates favorable conditions for students to develop essential and core competencies and assists students in improving their mathematical competence as a foundation for good learning. It also promotes necessary skills for society, in which mathematical communication skills are essential skills. The purpose of the research is to enhance students' mathematical communication skills while studying ellipse topics.
