Abstract

Mathematics learning in schools is still abstract and not yet relevant to students' lives. Mathematics learning should be linked to student activities such as scouting extracurricular activities. There are many scouting technical activities that can be used as contextualization in mathematics learning such as ceremonies, exploration, estimating, marching, pioneering, and semaphore. Thus, this study aims to identify mathematical concepts contained in scouting activities, especially in the construction of creative flagpole pioneering. This study is a qualitative study with an exploratory approach. Data collection methods used are observation, interviews, and documentation. The study was conducted on students who participate in scouting extracurricular activities at SMAN 2 Kendari, located on Jln. Sisingamangaraja, Rahandouna Village, Poasia District, Kendari City, Southeast Sulawesi Province. The results of the study show that in the pioneering flagpole creation building there are geometric concepts, namely rectangular, square, right triangle, acute triangle, obtuse triangle, right trapezoid, isosceles trapezoid, arbitrary trapezoid, right angle, acute angle, obtuse angle, overlapping lines and intersecting lines. and geometric transformations, namely rotation. These results provide recommendations to teachers to be able to use the pioneering building as an introduction to mathematical concepts.

Abstract

This study seeks to examine students' mathematical procedural fluency in addressing algebraic operation problems through the lens of metacognition. The research is qualitative in nature and employs an exploratory methodology. The instruments utilized in this study include mathematical procedural fluency assessments, metacognitive questionnaires, and interviews. The participants comprised three students from class VII of SMP Muslimin Samarang, each demonstrating fluent criteria in mathematical procedural fluency. The findings revealed that despite sharing the same procedural fluency criteria, the subjects exhibited varying metacognitive criteria: subject S1 displayed strong metacognitive criteria, subject S2 showed moderately strong metacognitive criteria, and subject S3 exhibited weaker metacognitive criteria. Several alternative strategies can be implemented to enhance learning and foster procedural fluency in relation to metacognition, including the use of diverse learning models, the development of instructional materials, the creation of culturally relevant questions, and the incorporation of engaging learning media.

Abstract

Errors in solving math story problems remain a common problem among students. This is due to the lack of in-depth analysis by teachers of the types of errors made by students based on Kastolan's theory, resulting in the same patterns of errors being repeated. Based on this problem, this study aims to identify and describe the types of errors made by students in solving mathematical story problems based on Kastolan's theory. This study uses a quantitative descriptive approach with a sample of 36 students in class X.E6 at SMAN 2 Bukittinggi, selected through purposive sampling. The research instrument was a story problem test on trigonometry consisting of five questions. The data were analyzed using descriptive statistics to obtain the percentage of each type of error. The results showed that 21 students (59.44%) made conceptual errors, 24 students (67.67%) made procedural errors, and 22 students (62.78%) made technical errors. Thus, procedural errors were the most dominant type of error made by students. These findings indicate the need for more systematic learning strategies and an emphasis on procedural understanding in solving mathematical story problems.

Abstract

This research is motivated by the importance of the impact of numeracy literacy skills on learning outcomes. In this literacy and numeracy skills are the basis that must be mastered by students as a reference for basic knowledge to know the next learning or material. This study aims to determine the influence of numeracy literacy on mathematics learning outcomes at SMAN 6 Padang. This study uses a quantitative research type using an ex post facto approach. The object of this research is class XII IPS. Data collection techniques use tests. In the research that the author did, there was no treatment like an experiment but rather what it was. This method uses a hypothesis test, namely to find out how much influence the independent variable has on the dependent variable which is carried out using simple linear regression analysis. The data analysis technique uses a paired sample t-test, which consists of the Shapiro Wilk normality test and the Linearity test. Based on the results of the study, analysis and discussion obtained from the one-sample normality test obtained a significance value of 0.076 0.05 while in the linearity test obtained a significance value (sig 2-tailed) of 0.575 0.05 which means that the data is normally distributed and there is a linear relationship. While in the paired sample t-test obtained a significance (sig. 2-tailed) of 0.027 0.05. In the results of the simple regression analysis Y = 50.713 + 0.249X. This means that the constant of 50.713 means that the consistent value of the learning outcome variable is 50.713. The regression coefficient X of 0.249 states that for every additional one unit of numeracy literacy ability value, there is an effect on learning outcomes of 0.249. The regression coefficient is positive so that it can be said that the direction of the influence of variable X on Y is positive. Based on the table above, it can be seen that 31 respondents produced a correlation value of 0.249. therefore, there is an influence of numeracy literacy on mathematics learning outcomes of SMAN 6 Padang.

Abstract

The implementation of e-didactics through the use of various digital tools and platforms in learning requires appropriate assessment techniques and student skills in using them to measure learning outcomes. This study aims to: (1) determine students' ability to solve Complex Analysis exam questions assisted by mathematical computer applications; (2) identify appropriate question formats to measure mathematical problem-solving abilities; and (3) measure the level of resilience and self-awareness of students during the exam. This study uses a qualitative descriptive approach. The researcher aims to explore the role of e-didactics assisted by the Learning Management System (LMS) and mathematical computer applications on the ability to solve analytical questions, resilience, and self-awareness of sixth-semester students of the Mathematics Education Study Program at a university in Bandung City. The context of this study is when students complete the Mid-Semester Exam (UTS) questions for the Complex Analysis course. The results of the study indicate that: (1) students' analytical abilities are in the sufficient category; (2) appropriate question formats to measure analytical abilities are multiple-choice and essay questions with analytical question types; and (3) the level of self-awareness and resilience of students during the application-assisted mid-term exam was also in the sufficient category. For further research, it is recommended that e-didactic studies not only focus on the evaluation stage, but also be reviewed from the perspective of the entire learning process.
