Abstract

The demands of high school education are not only increasingly complex and difficult subject content, students are also required to be able to think critically and reason in solving everyday problems. This mathematical ability is known as mathematical literacy proficiency. This is where the teacher's role as a facilitator who provides stimulus in the form of learning strategies, guidance and assistance when students experience learning difficulties is a key factor. For this reason, students as prospective mathematics teachers need to have good mathematical literacy skills and knowledge and skills to guide students to achieve 21st century abilities and skills. This research was conducted to apply a STEM approach in learning so that students can improve the mathematical literacy skills of students majoring in Mathematics Education as prospective teachers and introduce and equip them with knowledge about STEM. The research was carried out using problems related to the relationship between mathematics and digital images in STEM. Data is collected through tests and assessments of student activities that integrate STEM in solving problems. The research results show that digital images have the potential to help students understand mathematical concepts in various fields, especially computer graphics. Students' literacy skills also increased significantly at the significance level α = 0.05. Students' mathematical literacy proficiency level increased from 90% at maximum level 1 to 90% at minimum level 5

Abstract

This study aims to evaluate the strengths and weaknesses of teachers in the teaching process in terms of aspects of mathematics teacher competency. It describes how the four teacher competencies have been running in the learning process in the classroom based on students' perceptions related to student competencies themselves using Structural Equation Modeling data analysis techniques (SEM). The study population was all junior high school students in Merauke City, Papua. The method of sampling was used proportional random sampling, which is continued by simple random sampling, to obtain a total sample of 436 students. The data collection was carried out by distributing questionnaires to students' perceptions about the performance of mathematics teachers consisting of 48 questions in the form of a Likert scale. The results obtained that pedagogic and social competencies are competencies that affect student competencies with mathematics teacher pedagogical competence is most influential on student competencies. Therefore, to improve student competency, teachers need to improve pedagogical and social competence.
