Mathematical anxiety has a negative relationship with mathematics performance and achievement. Further explained, mathematics anxiety has an indirect effect on mathematics performance. This research explores sources or factors related to mathematics anxiety among engineering students at a private university in Indonesia. A total of 47 engineering students participated in this survey that randomly chosen based on gender, major, and age. Two main factors are affecting the mathematics anxiety of engineering students, namely internal and external factors. The results show that mathematics anxiety among engineering students is manifested into three aspects. Firstly, the home aspects are talking about the influence of parents and sibling. Secondly, society's issues are discussing self-efficacy, social reinforcement to hate mathematics, and social stereotypes. Lastly, the classroom aspects are talking about the traditional mathematics learning process and classroom culture, namely the experience of learning mathematics in classrooms and relationships between friends during learning. The details of the statements under the aspects also highlight unique problems and are not covered by previous research in mathematical anxiety. Next, differences in mathematics anxiety by gender and faculty were examined.

Indonesia has many cultures that can be used as a starting point in learning mathematics. Yet, many teachers still use conventional methods to provide explicit mathematical content without connecting with students' culture and daily activities. One of the learning approaches that can solve these problems is Realistic Mathematics Education (RME). This approach uses context as one of its characteristics containing students' culture and their daily activities. On the other hand, Wayang (Indonesian shadow puppets) and Mahabharata stories have the characteristics that can be a context in the learning of set. This research aims to design the Hypothetical Learning Trajectory (HLT) of the set using the RME approach through Wayang and Mahabharata stories, which are familiar with students' culture in Yogyakarta. This HLT will then be tested on students in further research until it becomes the Local Instructional Theory (LIT) on set. Students can study about set by grouping Wayang in Mahabharata stories based on their characters. The research result is the HLT of set through the context of wayang and Mahabharata stories containing learning goals, learning activities, and the conjecture of every activity. This HLT can be a promising solution to overcome students' difficulties in understanding the concept of sets and values in the cultural context to improve the students' character.

Applying critical thinking is an essential skill in the 21st century. However, teaching materials that do not facilitate students to improve these skills impact the achievement of learning objectives. Therefore, educators need appropriate teaching materials that encourage students to enhance their thinking skills. This study aims to develop teaching materials based on Realistic Mathematics Education (RME) to improve students’ critical thinking skills. The development model used is ADDIE consisting of Analysis, Design, Development, Implementation, and Evaluation phases. The instruments used, consist of validated student worksheets based on material experts and media experts, pretest questions, posttest questions, and the practicality of student worksheets. The results showed that the student worksheets developed were feasible regarding validity, practicality, and effectiveness. The validity of the student worksheets is indicated by the average score of two material expert validators and two media expert validators, each of which is in the good and excellent categories. The practicality of the student worksheets is denoted by the average value of student assessments included in the practical category. Then its effectiveness is shown by increasing students’ critical thinking skills after being given intervention using the student worksheets.

This descriptive quantitative study explored secondary school students’ reasons for receiving or not receiving private mathematics tutoring. It also explored the prevalent teaching methods private mathematics tutors use. A questionnaire was adapted to collect data from 1,309 Year 7 to Year 12 students (ages 11 to 17 years) in three countries: Brunei, Indonesia, and Iraq. The results highlight that students may receive private mathematics tutoring to pass national examinations and improve examination scores. Teachers also adapt to teaching approaches that enable students to achieve these teaching and learning goals. This study provides an initial understanding of the common reasons and teaching methods used in private mathetics tutoring across different contexts that prioritise high-stakes examination culture. The results provide implications for how private mathematics tutoring can be used to support effective teaching and learning compared to the high-stakes reasons it seems it promotes. The results also accentuate the need for families and other stakeholders to reconsider private mathematics tutoring as an opportunity to remediate the challenges students encounter in their normal classroom instruction to improve student learning.

Several studies have highlighted the existence of demotivated teachers in schools. There are several demotivating factors that influence the decisions and commitment that a teacher can acquire. The literature review allows us to characterize the factors that different authors identify to explain teacher demotivation. This article aims to analyze some of the factors that influence mathematics teachers' demotivation and the evaluation of the degree of demotivation in relation to work environment, teaching autonomy, extrinsic values, and students. The information was collected from a questionnaire consisting of 24 items, which was given to 121 active Albanian teachers teaching at different levels of education. These data were analyzed using a quantitative methodology. The independent variables gender, teacher's age, qualification, pupils' age, and type of school are also considered to perform a multivariate analysis. From the results obtained, we can state that the factors that generate the greatest demotivation are textbooks, political conversion and corruption, aspects related to the curriculum, and the costs they must bear. In addition, school status, curriculum changes, meritocracy, material costs, autonomy, and research significantly explain the demotivation of public sector teachers. It highlights the need to seek structured responses aimed at regulating teaching careers.

The mission of positive psychology is to mitigate negative emotions while bolstering positive ones, thereby influencing student engagement in classroom learning activities, including mathematics. This study elucidates the Realistic Mathematics Education (RME) approach within the framework of Islamic teachings—specifically, inheritance law and charity—in the context of fractions and number operations. Its objective is to alleviate mathematics anxiety, a prevalent negative emotion, and enhance well-being during mathematical learning. Drawing upon flow theory from positive psychology, the research endeavors to optimize mathematical well-being by crafting appropriately challenging questions. Employing a descriptive qualitative methodology, the study focuses on an Indonesian mother and her ten-year-old son, residing in Uithoorn, Amsterdam, Netherlands, belonging to minority groups in ethnicity and identity, with religion being a significant aspect of their lives. Data collection involves observation, interviews, tests, and documentation, with analysis employing data reduction, presentation, triangulation, and verification techniques. The study utilizes socio-religious problems as a context, one of the characteristics of RME, such as inheritance division, to design mathematical challenges. The findings demonstrate a marked transition from math anxiety to math well-being, manifested through heightened enthusiasm and cheerfulness in learning mathematics, particularly by the mother. Noteworthy transformations include increased engagement, generous gestures towards the teacher, and frequent smiling, contrasting with previous instances of math anxiety during learning sessions. Furthermore, the results indicate that RME facilitates comprehension of mathematical concepts and fosters understanding of the intersection between mathematics and Islamic life among minority groups, as detailed in this article.

Recognising the pivotal role of effective teaching practices in enhancing student learning outcomes, the National Council of Teachers of Mathematics (NCTM) has outlined a comprehensive framework of key strategies. However, empirical research on these practices remains limited. Therefore, this study aimed to investigate the extent to which mathematics teachers apply NCTM-identified effective teaching practices and examine potential differences attributable to teachers' gender and teaching experience. Adopting a quantitative approach and employing a descriptive survey, the study systematically assessed eight designated practices using a validated observation checklist in the Jazan Education Administration, observing 38 mathematics teachers during routine classes. The results indicated a moderate level of implementation overall, with ten practices demonstrating high application. Statistical analyses found no significant differences in practice implementation based on gender or teaching experience at the .05 level. The limitations included the study's relatively small sample size, potentially limiting generalisability, and the observational nature of the checklist, which may not fully capture nuanced teaching dynamics. Future research could focus on developing training initiatives to enhance educators' application of NCTM-recommended practices and undertake qualitative inquiries to understand barriers to integration and teachers' attitudes towards these practices. Finally, this study contributes to the discourse on effective mathematics teaching by providing empirical insights into current practices and highlighting avenues for further investigation and professional development in educational settings.
