Abstract

Mathematic has characteristics of abstract objects, so mathematical understanding is needed in studying mathematics. Until now, no research has examined students mathematical understanding viewed from multiple intelligences. This study aims to determine the profile of students mathematical understanding through diagnostic tests reviewed from multiple intelligences. This was a quantitative approach with population of all students in one of the junior high schools in Banda Aceh, Indonesia, and sample was 44 students selected by purposive sampling. Data collection was carried using multiple intelligence questionnaire and mathematical understanding test. Data analyzed using descriptive statistics. The results showed that students with mathematical logic intelligence able to define concepts verbally, interpret, identify, and distinguish concepts; students with linguistic, naturalistic, and existential intelligence able to define concepts verbally, interpret, and distinguish concepts; students with musical and kinesthetic intelligence able to define concepts verbally and interpret concepts; students with spatial intelligence able to interpret, identify, and distinguish concepts; and students with interpersonal intelligence able to interpret and distinguish concepts. The implication of this research is that teachers need to understand and realize that students' multiple intelligences are an important aspect that needs to be considered in delivering class material to improve students' mathematical understanding.

Abstract

Variables and expressions serve as bridges where students cross from arithmetic to algebra. Although variables and expressions are important concepts in middle school and high school mathematics, they are topics that many students find challenging, and many, in fact, do not develop a thorough understanding of these topics. This study aims to explore the epistemological obstacles students face in understanding and interpreting the concepts of variables and expressions. Based on these objectives, a qualitative research design with a phenomenological approach was chosen to achieve this research objective. The subjects in this study were 8th grade middle school students in the city of Medan, Indonesia. Tests and interviews were used to collect data. The data obtained were analyzed using an inductive approach. The data obtained are presented in narrative and graphical forms. Based on the research results obtained, six types of student errors in solving problems related to the concept of variables and expressions were identified. Overall, students' limitations in understanding and interpreting variables as something unknown is one of the triggers for epistemological obstacles. Teachers should give chances for pupils to debate and explain variables and expressions in the classroom to assist students gain a comprehensive knowledge of these mathematical tools.

Abstract

The process of solving absolute value problems is not only associated with the simplification of equations or inequalities. Students also need to pay close attention, ask the right questions, carry out the right strategies, and acquire adequate information. This step is essential to prevent students with good metacognitive ability from drawing wrong conclusions. The research discusses the metacognitive characteristics of mathematics education students in solving absolute value problems from the awareness, regulation and evaluation components. Participants consisted of 101 students from four state universities in the city of Malang. Data were obtained through written answers, transcripts of think aloud, and interviews. The data collected were analyzed to determine their metacognitive abilities in terms of awareness, regulation and evaluation components. The result showed that the metacognitive ability of low-skilled students only exists in the awareness component, which is thinking about what is being asked. Furthermore, those medium capable of the awareness component still lack adequate thinking ability. In the regulation and evaluation components, students do not realize that there are still inappropriate steps in solving problems and fail to check the correctness of their answers. However, high-ability students can solve problems in different ways and easily distinguish accurate information using effective strategies. Learn how the metacognitive characteristics of students in solving non-routine absolute value application questions, provides space for educators to be able to create appropriate learning models.

Abstract

Representational transformation skills significantly influence students' success in problem-solving. Students who struggle with representational transformation skills are often less adept at utilizing mathematical ideas and relationships, and vice versa. Therefore, this study used a qualitative, descriptive-interpretive approach to examine students' semiotic representation skills when solving mathematical problems. The research was conducted in a Year 9 classroom in a public school in Bandung, Indonesia, with 30 participants divided into high, middle, and low-ability groups based on their level of mathematical ability. Data was collected using both test and interview techniques. The results indicated that students in the high and middle ability groups had adequate skills in algebraic treatment and conversion from algebra to geometry and verbal expression skills for constructing algebraic expressions and converting verbal statements into mathematical equations. In contrast, the low-ability group demonstrated a lack of semiotic representation skills in problem-solving. These findings highlight the importance of transformation and conversion skills in mathematical problem-solving activities and can be valuable information for teachers and observers of mathematics education.

Abstract

Mathematical creativity provides space for students to express their ideas. Hence, the mathematical activities should support their ability to pose and solve problems. However, students are not used to them and have difficulty in proposing and solving creative problems. The ideas proposed are in the form of problem-posing with free situational and semi-structural types and their solutions. This study aims to describe the level of creativity of students in problem-posing and problem-solving conditional probability problems. The research method used was qualitative, and participants were 35 second-year preservice mathematics teachers. The result indicates that, in posing a free situational type problem, students were generally at level 3 (creative) while, in posing a semi-structural problem, students were generally at level 0 (not creative). Although, the students in each type of problem-posing task were at the category of level 4 (very creative), level 3 (creative), level 2 (quite creative), level 1 (almost creative), and level 0 (not creative). This shows that there is a need for habituation for students to pose and solve problems, especially those that are related to semi-structural type problems.

Abstract

Relational reasoning plays an important role in helping students to understand mathematical concepts. The student's ability to distinguish patterns or objects is one of the understandings of mathematical concept indicators. The anomaly dimension is part of the relational reasoning that students need to be able to determine a pattern or object in mathematics. This study aims to reveal the student's relational reasoning ability of anomaly dimension in solving number pattern problems in terms of gender differences. The subjects of this study are 52 grade-8 students in one of Muhammadiyah Junior High Schools in Kartasura. We used two similar problems on number patterns to disclose the student's ability to identify the pattern deviation in solving problems. The two selected students had relatively similar in their mathematical abilities. The finding showed that female subject met the three anomaly dimension indicators: identification, interpretation, and adaptation. Conversely, male student cannot fulfill the anomaly indicators. He cannot recognize pattern deviation in the formed mathematical model. He also failed to identify a pattern different from the two problems. Although the subjects interviewed were limited, the finding provided the insightful into the differences in anomaly reasoning abilities in male and female students

Abstract

Mathematical literacy is an important ability for students in Indonesia to face the implementation of minimum competency assessment and learning in the 21st century.This study aims to describe students' mathematical literacy skills in solving problems on pattern material in the Bengkulu local context. This study used a descriptive qualitative design. The research subjects were 30 students grade VIII from five schools in Bengkulu City. Subject selection through purposive sampling technique based on the level of intelligence with the number of each school is six students. Data were collected through interviews and mathematical literacy test using description questions that have been validated and tested. The data analysis consists of data reduction, data presentation, and concluding. The findings of this study are that students with low to moderate knowledge tend to have literacy skills at level 2. In contrast, students in the high knowledge group have literacy skills at level 3. Many students have used mathematical arguments to solve literacy problems but did not use concepts correctly.Students have not used the model structurally at the modeling stage, which resulted in errors in problem-solving and representation. Based on this, teachers need to emphasize the concept of material and mathematical modeling in learning.

Abstract

Technology has become a crucial part of the learning process and a facilitator of the interaction between students and teachers. Spatial ability is a crucial ability in mathematics learning and success in STEM. In this case, Augmented Reality (AR) in mathematics learning can facilitate the abstraction of mathematics that represents a new representation of mathematics concept. The objectives of this studywere to develop an application using AR which was further used to improve the spatial ability of Junior High School students.Meanwhile, the method used in this study was RD using the ADDIE model and quantitative approach through t-test. In this case, 64 students of 8thgrade in Junior High School were involved as the research samples, where 32 students were in the control class and 32 students were in the experimental class. The results of this study were that the AR application was feasible to use in mathematics learning and its application enabled teacher and students to learn solid geometry using Augmented Reality with the object that can be manipulated, interact in real-time, and measure objects in the real world. It was also obtained that the learning outcomes of students who used the application were higher than the learning outcomes of students who did not use application, indicating that the application could increase stdudents spatial ability.
