The purpose of this study was to describe how digital natives as preservice mathematics teachers learn mathematics. The research subjects were 30 students of the Mathematics Education Study Program at the Universitas Negeri Gorontalo. This research is a descriptive qualitative research with data collection techniques are semistructured interview, questionnaire using Mentimeter, and documentation. Data collecting held in 2022. First, they were interviewed to obtain information on how they studied college mathematics courses such as calculus or differential equations. After obtaining the methods they used, they were then asked to fill out a questionnaire via Mentimeter. From the results of the interviews and filling out the questionare, it was found that their ways of learning were by watching YouTube, reading books, discussing mathematics material with their peers, searching for learning material from the internet, and also using mathematical applications to help them solving problems. Although everyone has different preferences for which method they like the most, in general, they combine all five learning styles. When they were asked to choose the method they liked the most, 50% of them choose watching YouTube; 43% prefer to learn from books; and 6.67% choose to use mathematical application. The mathematical applications they use are dominated by Photomath. Other applications used are Qanda, Brainly, Colearn, Mathway, MathLab, Mathenchanter, Geogebra, Snap Quiz, and Wolfram Alpha. The results show that book is still relevan to use in this digital age.

This study aims to describe the algebraic reasoning of students with logical-mathematical Intelligence and visual-spatial Intelligence in solving algebraic problems. This research is a qualitative descriptive study. The subjects of this study were students of eighth grade students of junior high school totaling 35 students. The results of the research data were analyzed by describing the algebraic reasoning of students with logical-mathematical Intelligence and students with visual-spatial Intelligence on each of the defined indicators. Data collection techniques are carried out by tests, observation, interviews, and documentation. The results showed that the student with logical-mathematical Intelligence and visual-spatial Intelligence in pattern seeking indicators, were able to identify, represent what was known and asked in the problem and find the constituent elements of the pattern. In the pattern recognition indicator students with logical-mathematical Intelligence find a relationship between elements and the similarity of the relationship of each element by thinking about it and accompanied by logical reasons. Students with visual-spatial Intelligence find a relationship between elements and the similarity of relations between each element by conducting experiments by writing down each process completely. In the generalization indicator, students with logical-mathematical Intelligence and students with visual-spatial Intelligence are able to model the situation or problem given and solve it correctly, and they are able to find a general rule that can be used to solve problems.

The objective of this study is to describe the mathematical reasoning abilities of eleventh-grade students at public senior high school 1 Limboto, focusing on matrix material. This type of research employs quantitative methods and descriptive approaches. The subjects of the research consisted of 30 students from grade XI (IPA 1). Data collection was conducted through tests designed to measure various indicators of mathematical reasoning abilities. The results indicated that, overall, students' mathematical reasoning abilities fell into the moderate category, with a percentage of 69.33%. Further analysis based on the reasoning indicators revealed varied results: the ability to write mathematical statements was categorized as moderate (82.22%); the ability to perform manipulations was categorized as high (86.67%); the ability to find patterns in mathematical phenomena was moderate (74.67%); and the ability to draw conclusions from solutions was categorized as very low (39.26%). These findings highlight the need for greater attention to drawing conclusions in the learning process so that students can enhance their overall mathematical reasoning abilities.

This study aims to improve students' mathematical numeracy skills through the Problem Based Learning (PBL) approach. This research was conducted at SMK Negeri 1 Bonepantai in the 2024/2025 academic year. The subjects of this study were 13 class X-TKJ students. Data collection techniques used were observation and tests. The research instruments used were numeracy ability test instruments, instructor activity observation sheets, and student activity observation sheets. This study was conducted in two rounds. This is evident from the fact that teacher activities with good and very good criteria increased by 19.04 percent from 76.2% in cycle I to 95.24 percent in cycle II. Additionally, with high and very strong criteria, student activities rose by 41.14 percent from 47.06 percent in cycle I to 88.2 percent in cycle II. Additionally, students' arithmetic numeracy skills improved by 23.08 percent, rising from 6 1.54 percent in cycle I to 8 4.62% in cycle II. As a result, the action success indicator has been attained by the success indicators for teacher and student observation activities as well as the students' mathematical numeracy skills. Therefore, the use of the Problem Based Learning (PBL) model has been scientifically proven to improve the mathematical numeracy ability of Class X students of SMK Negeri 1 Bonepantai.

Mathematical reasoning ability is necessary for solving mathematical problems. Therefore, the intent of this study is to enhance students' mathematical reasoning ability through the application of a discovery learning model focused on quadratic function material. This research is Classroom Action Research, designed by Kemmis and McTaggart. The research subjects were 32 students of grade IX at Public Junior High School 1 Tapa. This study used tests for mathematical reasoning, teacher and student activity observation sheets, and questionnaires. The data was analyzed quantitatively and qualitatively using percentages. The findings of this study indicate an increase in students' mathematical reasoning ability after applying the discovery learning model. Teacher activities in cycle I with a percentage of 73.68% increasing in cycle II to 89.47%; student activities in cycle I with a percentage of 72.50% increasing in cycle II to 87.50%; questionnaire results in cycle I only 20 people with a percentage of 62.50% increasing in cycle II to 28 people with a percentage of 87.50%; and the results of students' reasoning ability in cycle I only 23 people with a percentage of 71.87% increasing in cycle II to 28 people with a percentage of 90.62%. There were still 4 people with a percentage of 9.28% who scored <75. In cycle II, the teacher activities, student activities, questionnaires, and reasoning skills met the success indicators.

It is important for schools to improve students' mathematical communication. However, a preliminary study at Public Middle School 1 Bulango Selatan revealed that some students still struggle to solve problems given by the teacher, particularly those related to determining the length of a side of a flat shape, especially in the context of congruence and similarity. Therefore, the intent of this study was to determine the effect of the flipped classroom learning model assisted by Instagram on students' mathematical communication at Public Middle School 1 Bulango Selatan. The method used in this study was an experimental method consisting of an experimental class and a control class with a research design used, namely a post-test-only group design. We conducted a t-test data analysis on both the experimental and control classes. The findings of the study showed that the t-count was greater than the t-table value; specifically, the t-count was 2.083, which is greater than 2.042, leading to the rejection of H0. Thereby, it can be concluded that learning using the flipped classroom learning model on the material of congruence and similarity of flat shapes can affect students' mathematical communication skills.
