The COVID-19 pandemic has catalyzed the widespread adoption of distance learning, necessitating a comprehensive understanding of how teacher knowledge evolves within the context of Teacher Professional Education (TPE) programs. Some research endeavors may employ evaluation methodologies that inadequately capture the nuanced dimensions of knowledge, highlighting the necessity for greater incorporation of evidence-based approaches in the formulation and assessment of teacher development initiatives. This study employs a qualitative methodology to explore the evolution of Mathematics Teachers' Specialized Knowledge (MTSK) within the framework of a TPE program. Data were gathered through the engagement of three educators in the preparation and execution of lessons on permutation and combination via a Learning Management System (LMS), coupled with in-depth interviews. The findings underscore the TPE program's role in fostering collaborative learning environments through participation in online educational communities. Teachers are shown to be increasingly integrating technology into their pedagogical practices, albeit with varying degrees of proficiency. The presence of Professional Learning Communities (PLCs) is identified as instrumental in supporting educators in refining instructional strategies to enhance teaching effectiveness. Nevertheless, there remains a subset of teachers necessitating more profound and more comprehensive content knowledge about their subject matter. These insights emphasize the importance of designing TPE programs that offer sustained and adaptable professional development opportunities to facilitate continuous growth among educators. Consequently, it is recommended that online learning communities geared toward addressing the diverse learning requirements of students be established, thereby aiding in the identification and resolution of pedagogical challenges.

The focus of this article is to identify PBL-based mathematics learning innovations and PBL-based mathematics learning outcomes. The method used is qualitative and the type is a case study. Data collection techniques were carried out using interviews, observation, and documentation and data analysis was carried out in three activity streams that occurred simultaneously in the data collection process, namely: data condensation, data presentation, and conclusion drawing/verification. The research results stated that the stages of PBL-based mathematics learning consisted of three main steps, namely the teacher providing an explanation of the material first before presenting the problem, the teacher giving work papers, and students being directed to complete the work papers in groups. This PBL model indicates that teachers have good managerial skills in the learning process. The results of mathematics learning using the PBL method indicate the delivery of material during the learning process, and students' social skills during learning. The PBL method has an important meaning in seeing the success of learning and education. Both specifically in mathematics and all other subjects. Considering learning outcomes can be used to prepare learning evaluations.

The aim of this research is to determine learning innovation and increase student motivation in mathematics lessons based on the PBL method and QR-Code media. The method used is qualitative with a case study type. Data was obtained through interviews, observation and documentation. Data analysis uses three simultaneous steps, namely data condensation, verification and presentation. The research results state that learning innovations based on QR-Code media can speed up understanding in the learning process, clarify the presentation of material considering that it is displayed using gadgets owned by students, learning time can be conditioned while eliminating students' boredom, and most importantly increase students' learning motivation in mathematics subjects. Student motivation is slowly being built using QR-Code media, making learning more effective, active and fun. The effectiveness of learning is influenced by the learning methods and media used. The two are interrelated, where the choice of a particular method will influence the type of media that will be used. In the sense that there must be a match between the two to realize the goals of mathematics learning.

One of the mathematics materials students considers difficult is integer material. This affects the results of AKM Numeracy, which is not optimal, especially in the number domain. This study aimed to develop a numeracy literacy-based mathematics test instrument on whole number material in grade V elementary school. This type of research is Research & Development with the development stages of the Thiagarajan 4D model (defining, designing, developing, and disseminating). The instruments developed include question grids as guidelines for making questions, questions and answer keys to test students' numeracy skills and scoring guidelines as a tool for giving student scores. The number of questions developed was three multiple-choice questions and seven complex multiple-choice questions. The principal and fifth-grade teacher validated this test instrument and obtained very valid results. The instrument was tested on fifth-grade students of SDN Kasembon 3 in the 2023/2024 school year and received the results of the item validity test getting a valid level on each item, the reliability test getting a high level, the differentiator test getting a sufficient and reasonable level, and the difficulty test getting an easy and moderate level. So, this numeracy literacy-based mathematics test instrument on integer material is feasible and can measure numeracy skills very well

Errors in solving mathematical problems, especially in the material of sets, are still widely found in junior high schools. This study aims to describe the types of student errors and the factors causing them in solving problems about sets based on the Newman Procedure. The study was conducted on 31 eighth-grade students at one of the state junior high schools in Malang City, with three students (S-1 to S-3) selected as subjects by purposive sampling. The main instrument was the researcher, with supporting instruments in the form of tests and interviews. Data analysis was carried out using the Miles & Huberman model. The results of the study showed that subjects S-1 to S-2 misunderstood the problem (misunderstood what was actually known and asked in the problem incompletely), while S-3 did not. All subjects experienced transformation errors (wrong writing of mathematical models/formulas), process skills (miscalculations/not continuing the procedure), and final answers (wrong conclusions). The main causal factors include lack of reading accuracy, weak conceptual understanding, and errors in calculations and procedures. The implications of this study indicate the need for learning strategies that emphasize conceptual understanding, accuracy, and more systematic procedural solutions.

This study aims to describe students’ misconceptions in solving fraction problems based on their level of belief. The research method employed is qualitative, with a descriptive research approach. Subjects were selected students who experienced misconceptions in solving problems. The results of examining students’ answers showed that out of 27 students, 18 did not know the concept, and 9 had misconceptions. Selected 5 students who experienced misconceptions as subjects to ensure data variation due to similarities in the answers or responses given. The misconceptions made by the subjects include: 1) Generalization misconception occurred because the subjects made mistakes in explaining the meaning of numerator and denominator of fractions and mistakes in applying the concept of addition and substructions of fractions; 2) Calculation misconception occurred because the subject made mistakes in calculating fractions and mistakes in simplifying fractions; 3) Notation misconception occurred because the subject made mistakes in using operation symbols and mistakes in writing numbers; 4) Language misconception occurred because the subject made mistakes in converting information into mathematical language. To overcome this problem, teachers are advised to provide a deeper conceptual understanding and practice problems regularly to improve students' understanding.
