Prospective teachers' understanding of the use of technology in mathematics learning through the TPACK framework. With technology becoming increasingly important in education, a strong understanding of TPACK is crucial for prospective teachers to design effective learning experiences. This study aims to investigate prospective teachers' understanding of the TPACK framework. This study is a qualitative research that used a single case design to investigate prospective teachers' understanding in the TPACK framework and involved teachers N=6 from mathematics education at Singaperbangsa University in Karawang. Three types of data were collected over 4 weeks, namely weekly observations, descriptions of progress reports, and lesson designs developed. The results of this study showed that most of the pre-service teachers had a limited understanding of technology integration in mathematics teaching. They tended to focus on the use of technology without paying attention to relevant mathematical contexts or effective pedagogical strategies. However, some pre-service teachers showed a better understanding of how technology can be used to support meaningful mathematics learning. The finding of this study is the need to develop training programs that strengthen pre-service teachers' TPACK skills, including integrated practical experiences and reflective learning on the use of technology in mathematics contexts. Through this research, it is expected that prospective teachers can deepen their understanding of how to integrate technology when they teach by considering aspects of content, pedagogy, and technology holistically in accordance with the TPACK Framework. The implication of this finding is the need for training programs in developing prospective teachers' TPACK competencies.

Kata kunci: berpikir aljabar, discovery learning, generalisasi Abstract: This study aimed to analyze the algebraic thinking ability of high school students by implementing the discovery learning model. The indicators used to assess algebraic thinking ability include generalization, abstraction, dynamic thinking, analytical thinking, organizing, and modeling. The study employed a descriptive method with a qualitative approach. The subjects were 17 students from class X-2 at SMA Plus Ulumul Quran Al Mustofa who had undergone learning using a discovery learning model and completed a test on algebraic thinking ability. Three students were selected: one student with the highest score, one with a score around the average, and one with the lowest score. The data were collected through tests and interviews and then analyzed using categorization, reduction, presentation, interpretation, and conclusion-drawing techniques. The results showed that the student with the highest score can implement almost all indicators of algebraic thinking ability except analytical thinking. Students with scores around the average are able to implement generalization and dynamic thinking indicators in algebraic thinking ability. Students with the lowest scores are able to implement generalization indicators in algebraic thinking ability. These findings suggest that the learning process significantly influences students' algebraic thinking ability, so teachers should apply the right learning model to develop students' algebraic thinking ability. Keywords: algebraic thinking, discovery learning, generalization

This research is based on the mathematics learning outcomes of elementary school students which are still low in terms of student learning outcomes. The current study reveals that as many as 66.67% of students have not been able to achieve the minimum requirements, especially in the section of geometry; reflecting a need to improve mathematics learning outcomes. This gap in learning outcome is due to the fact that a majority of students tended to be passive during learning. The STAD learning model is a learning model that emphasizes student activities and interactions for learning mathematics in the classroom. The research design used in this study is a one group pretest posttest design. The sampling method used in the study was purposive sampling from a class of thirty elementary school students with issues related to mathematical abilities. Data collection techniques consist of primary sources in the form of tests, interviews, and observations, while secondary sources include documentation and literature studies. The data analysis technique used is the t-test (or using the Wilcoxon test if the data is not normally distributed), and the Gain Test. The results showed that there is a positive influence of STAD model on learning outcomes.

In Euclidean geometry, parallelism constitutes a foundational concept from which numerous geometric ideas are derived. Despite its fundamental role in geometry and its importance in developing deductive and logical reasoning, research on the concept of parallelism—particularly concerning students’ learning obstacles and corresponding didactical approaches—remains limited, especially in higher education contexts. This study investigates the construction of theorems related to parallelism conditions by examining learning obstacles and implementing a GeoGebra-based didactical design within the framework of the Theory of Didactical Situations. Employing a qualitative approach with a phenomenological hermeneutic design, the study involved 64 undergraduate students from the Mathematics Education Department of a public university in Aceh, Indonesia, to identify the learning obstacles, and 35 students who participated in the implementation of the designed instructional intervention. Data were collected through document analysis, interviews, classroom observations, and audio–video recordings. The data analysis followed the three stages proposed by Miles and Huberman: data reduction, data display, and conclusion drawing. The findings revealed that students’ understanding of the theorems concerning parallelism conditions was impeded by three primary types of learning obstacles: epistemological, didactical, and ontogenic. To address these challenges, a GeoGebra-based didactical design was developed and implemented. The results demonstrated that this design effectively mitigated the identified obstacles and facilitated students’ construction of the theorems of parallelism conditions. Furthermore, the implementation appeared to foster a gradual shift in students’ learning orientation from procedural toward conceptual understanding, although this transition was not entirely uniform. Finally, the study highlights the pedagogical significance of integrating didactical situation theory into the learning process and employing dynamic visualization tools such as GeoGebra to support the transition from empirical to deductive mathematical reasoning.
