Abstract

Abstract: Mathematical understanding, particularly algebra, is essential in education. One effort to reduce student errors in learning can be achieved through an in-depth study of the relationship between students' emotional intelligence and the learning process. Emotional intelligence in learning mathematics is the ability to control one's emotions, manage, and express emotions towards others. Emotional intelligence is crucial for understanding the lessons delivered by the teacher. This research aims to investigate the relationship between student errors and the level of emotional intelligence by applying scaffolding to middle school students. The method used in this study is the correlational research method because it aims to determine the relationship between variable X (emotional intelligence) and variable Y (errors). The study population consisted of eighth-grade students at SMPN 1 Saradan in the 2022/2023 academic year, distributed in one class with a total of 30 students. From this class, 3 students were randomly selected as samples using purposive sampling technique. The instruments used in this research were an emotional intelligence questionnaire about mathematics and a mathematics error test on algebra material. The data processing and analysis technique in this study used correlation tests. The results of the correlation test in this study show that there is a significant relationship between emotional intelligence in mathematics and students' mathematical errors, with a correlation coefficient of 0.887, indicating a strong correlation. Based on these results, the conclusion can be drawn that students with high, moderate, and low emotional intelligence will produce better mathematics learning outcomes with the application of scaffolding. This activity is crucial, especially for teachers to understand students' difficulties and errors, aligning with the teachers' ability to better recognize students' characteristics.         Keywords: emotional quotient, newman’s errors, algebraic arithmetic operations, scaffolding.DOI: http://dx.doi.org/10.23960/jpmipa/v25i1.pp236-247

Abstract

Undergraduate students often struggle to shift froam procedural to conceptual understanding when learning linear transformation. They tend to focus on mechanical procedures while neglecting the underlying concepts. Textbooks play a crucial role in developing conceptual understanding through well-structured and meaningful exercises. Praxeological theory, which maps the relationship among mathematical tasks, techniques, supporting technologies, and underlying theories, provides a comprehensive framework for such analysis. This study aims to analyze linear transformation exercises in Elementary Linear Algebras (11th edition) by Howard Anton and Chris Rorres using a qualitative content analysis based on the praxeological framework. The findings reveal that most exercises have the potential to foster deep conceptual understanding, particularly when learning activities do not stop at the technical stage. Practically, the study offers insights for lecturers and textbook developers in designing exercises that balance procedural demands and conceptual reasoning, thereby enhancing meaningful learning of linear algebra in higher education.

Abstract

Geometric transformation is a branch of mathematics that focuses on the transformation (bijective function) of geometric objects in a plane or transformation in . One of the topics discussed in geometric transformation is the properties of the composition of two isometries. Generally, topics in geometric transformation are studied using an axiomatic geometry approach that requires strong geometric visualization skills. This research aims to study the composition of two isometries through an alternative approach, specifically linear algebra. The study focuses on deriving the properties of the composition of two isometries, namely translations, reflections, and rotations, while considering their algebraic forms. The research methodology employed is literature study and deductive reasoning in accordance with mathematical syllogism. The results of this research are theorems that state the properties of the composition of two isometries. Based on the findings of this study, it can be concluded that the properties of the composition of two isometries can be derived using a linear algebra approach.

Abstract: The concept of reflection in three-dimensional is almost the same as the concept of reflection in the two-dimensional. However, the mirror in three-dimensional is in the form of flat plane.  Reflection in three-dimensional is a function that maps each point in such a way to meet the following requirements: distance between the prapeta point and the mirror is the distance between the mirror to the mapping result, the line connecting prapeta point with the mapping must be perpendicular to the mirror, and the structure and its reflection must be congruent. To get the reflection function, it can be carried out analytically. First, take flat plane as a mirror and the point that will be reflected in three-dimensional. A straight line is made through that point and it is perpendicular to the mirror, so the breakpoint can be determined. By utilizing shifts in three-dimensional, translucent point can be shifted in line with vector where is the point and is the starting point. So, the point as the result of mirroring can be obtained. The results of this study reveal that: mirroring in three-dimensional is a transformation because its function is a bijective. Reflection is involution which means that the results of twice multiplications are identity. Mirroring is not commutative. The result of twice parallel reflection composition can be called as reflection. The result of n multiplication of mirroring composition parallel to the coordinate and there is a distance is called as reflection.Keywords:Involution, Composition, Transformation.

Abstract

The curriculum currently applied at the junior high school level is Curriculum 2013. This curriculum focuses on student learning activities. In a sense, knowledge must be actively built by students themselves. This paradigm has been known for a long time. At least since the introduction of the concept of active student learning in 1984 by Professor Dr. Conny R. Semiawan. However, in reality the teaching and learning process that occurs is that the teacher remains the center of attention when the teaching and learning process takes place in the classroom. In other words, those who are active in learning are still teachers and students sitting quietly listening to the teacher's explanation. The challenge is whether mathematics teachers are willing and brave to change the mindset from "teacher as a learning center" to "students as a learning center". To create a teaching and learning process with "students as the learning center", of course, it must be started from the making of the learning design to the practice of its application in the learning process in the classroom. In line with these wishes and intentions, this service activity answered by providing "Training and Assistance in Mathematics Learning Practices with the" MiKIR "Approach to Improve Analytical and Algebraic Reasoning Ability for mathematics teachers who are members of the Mathematics MGMP SMP Sragen Regency. In this case, the "MiKIR" approach is interpreted as a learning approach which, when applied in a teaching and learning process, occurs in students’ situations and conditions: experiencing, interaction, communication, and reflection both between students and students and students and teachers and that means "Students as a learning center".
