The main objective of this study is to examine the concept of geometric transformation contained in the Keris motif, the Keris, which is the main object in this study, namely "Keris Kyai Tengara". This research is included in qualitative research using an ethnographic approach. This study's data collection process was done through observation, documentation and interviews with Kris's caretakers and mathematicians. The results of this study indicate that the motifs in the kyai tengara kris apply the concept of geometry transformation. The idea of translation is found in the blue fan motif, the concept of reflection is found in the pattern of animal motifs on the kris frame, and the idea of dilation is found in the pattern of elephant wings on the kris.

Mathematics anxiety is one of the major barriers to students’ achievement and positive attitudes toward learning mathematics. Conversely, a growth mindset is considered a protective factor that fosters learning resilience. This study aims to explore the narratives of students with high levels of mathematics anxiety in relation to their growth mindset. A qualitative narrative approach was employed with three 11th-grade high school students in Malang Regency, Indonesia, selected purposively based on their scores on the Math Anxiety Questionnaire (MAQ). Data were collected through semi-structured interviews, written reflections, and field notes, and analyzed using thematic narrative analysis. The findings reveal five major themes: (1) initial negative perceptions of mathematics, (2) emotional responses to failure such as nervousness, frustration, or shame, (3) efforts to recover through diverse coping strategies, (4) social support from teachers, peers, and families that influences resilience, and (5) indications of growth mindset reflected in the belief that effort is more important than innate talent and mistakes are part of the learning process. These results highlight that although high mathematics anxiety poses challenges, a growth mindset can serve as a protective factor in building students’ learning resilience. This study contributes to the literature on the intersection between mathematics anxiety and growth mindset and provides practical implications for teachers to create a classroom climate that fosters positive mindset development.

In this era of the 4.0 revolution, society is expected to be able to think creatively, namely generating new ideas to solve various problems in daily life and preparing for the future. Enhancing creative thinking ability is considered one of the main learning objectives that is important to be improved in mathematics education. To think creatively in mathematics, students need to understand and actively engage in calculation processes as well as solve problems related to numbers and symbols, which is associated with numerical ability. The objectives of this study are: 1) To describe students' creative thinking abilities in solving mathematical problems based on high numerical ability 2) To describe students' creative thinking abilities in solving mathematical problems based on moderate numerical ability 3) To describe students' creative thinking abilities in solving mathematical problems based on low numerical ability. This research is a qualitative descriptive study. The data collection techniques include tests, interviews, and documentation. The research subjects were students of class VII B at SMP Negeri 1 Tamanan, with six students selected as subjects: two with high, two with moderate, and two with low numerical ability. The results of the study showed that students with high numerical ability met the indicators of fluency and flexibility, students with moderate numerical ability met the fluency indicator, and students with low numerical ability did not meet the indicators of creative thinking ability.
