Abstract

Students' low critical thinking ability in learning mathematics is a major problem in research. This needs to be overcome by implementing learning that provides opportunities for students to develop their thinking ability rationally and well-structured in learning mathematics. One learning model that supports this learning is the Connected Mathematics Project (CMP) learning model. This study aimed to describe quantitatively the implementation of the CMP learning model on students' critical thinking ability in mathematics. This type of research is quasi-experimental with a one-group pre-test and post-test post-test design. The research instruments were observation sheets and tests. The results showed that the application of learning observed in 4 meetings in terms of 9 student activities in learning in the sample group met the criteria for being effective. The student's critical thinking ability through the paired t-test showed a significance value of 0.00, which was smaller than the alpha level of 0.05, meaning that there was a significant difference in the average score from the pre-test to the post-test. Furthermore, the n-gain value obtained is 0.36 (medium). Thus, it was concluded that implementing CMP learning on students' critical thinking ability was effective.

Abstract

This study aims to describe the numeracy literacy skills of PGMI students at UIN Raden Intan Lampung in solving math problems. Referring to the results of international surveys, one of which is PISA, Indonesian students' achievements are still below the global average score. Therefore, PGMI as one of the study programs, is expected to be able to produce qualified MI teachers. As prospective teachers, PGMI students must have the ability to think at a high level. The data obtained shows that the numeracy literacy skills of students still need to be analyzed further to determine the level of numeracy literacy skills. The research method used is the qualitative descriptive analysis method. The instruments used were descriptive tests and interviews. Data analysis used in this study uses the following steps: Data Reduction, Data Display, and Verification. The subjects in this study were 91 PGMI students in the class of 2020. The results showed that the numeracy skills of PGMI UIN Raden Intan Lampung class 2020 students in solving math problems were sufficient. This is shown in the research results that only 22.09% of students can use various kinds of numbers and symbols in the first indicator, 13.08% of students can analyze information displayed in various forms in the second indicator, and only 4.36% can interpret all analysis questions to make the right decision in the third indicator.

Abstract

The focus of the PISA 2022 assessment is on the subjects of Mathematics, Language and Science. Therefore, these subjects are compulsory subjects at every level of education. Because learning activities are the most important activities, the success of a learning activity is measured by the learning outcomes that have reached completeness or failed. Prediction of completeness or failure can be done by classifying data using the K-Nearest Neighbors (KNN) algorithm using the RapidMiner application. The KNN algorithm is one of the classification methods for a set of data based on learning data that has been classified before. The data used are student learning outcomes in Mathematics, Indonesian Language and Science subjects at the junior high school education level in Padang city. This research aims to predict student learning outcomes in Mathematics, Indonesian and Science subjects based on student score completeness by comparing various k values to obtain the best performance of this algorithm. The results obtained after analyzing the KNN algorithm are Classification using the KNN algorithm is most accurate when the value of k = 5 and k = 7. Where by using the value of k, the accuracy of the KNN algorithm reaches the maximum result of 94.12%. Thus, this algorithm can help teachers to predict or find out how appropriate student completeness.

Abstract

Reasoning and proof is the ability to arrange patterns, make conjectures, test conjectures, and carry out logical proof, which can be seen as negative or positive for students when solving proof problems requiring reasoning skills. Prospective mathematics teachers in the Mathematics Education Study Program of FKIP Universitas Sriwijaya became the subject of this study. As the research instrument, the questionnaire was designed to explore students' opinions and responses to problems with significant logical difficulty. Sentiment analysis was used to analyze the opinions of prospective mathematics teachers on reasoning and proof questions by grouping positive and negative opinions. The technique used in this study uses the Naïve Bayes algorithm. The classification results in this study were 58.2% positive and 41.86.7% negative, with a total of 70 data. The final result achieved an accuracy value of 53.33%, signifying the reliability of the Naïve Bayes algorithm in understanding and classifying the complex spectrum of sentiments expressed by students. The implications of these findings go beyond sentiment analysis, providing valuable insights for educators, curriculum developers, and policymakers in designing learning strategies and educational policies that can improve mathematics students' reasoning and proof abilities.

Abstract

Spatial thinking is important in learning Science, Technology, Engineering, and Mathematics. Numerous studies about spatial ability in various fields like mathematics, neuroscience and phycologist considered various factors such as gender, age, or demography. However, a few studies are still about enhancing spatial ability in the context of mediated pedagogies. This study aims to describe spatial research on mathematics education, especially related to the intervention or learning design of spatial reasoning. A bibliometric study is employed to determine the research trend of spatial reasoning, especially related to teaching practice. The review follows a structured design consisting of several stages of the PRISMA method. From 652 documents about spatial in mathematics education gathered from the Scopus data, it is reduced to 40 documents regarding spatial reasoning in mathematics education. Further, only 19 documents about intervention and practice in enhancing spatial reasoning exist. This study may benefit researchers in mathematics education by showing the development and trend of spatial reasoning research and suggesting new directions for future research.

Abstract

Ethnomathematics is a science that studies the existence of mathematical concepts in social culture. One of the cultures in Indonesia is traditional games, which are a reflection of local wisdom. Traditional games can be linked to mathematics learning through an ethnomathematics approach. One example is the game of porok. The Porok game is among the most popular traditional games in Penaga Village, Bintan Bay and the Riau Islands. This game can potentially be explored regarding its use in mathematics learning. Thus, this research aims to dig deeper into the mathematical concepts and activities of the porok game as a form of ethnomathematics. This research uses a qualitative approach with an ethnographic design. The data source for this research is the head of the Dang Merdu studio in Penaga Village, Bintan Regency. Data collection was carried out through observation, interviews and documentation. The data analysis technique is carried out through 4 stages of analysis: domain analysis, taxonomic analysis, componential analysis, and cultural theme analysis. The research found basic activities and mathematical concepts in this game. The mathematical activities obtained are counting, measuring, explaining, playing and planning. Apart from that, this game has mathematical concepts, namely, value comparison, addition, geometric figures and probability, arithmetic sequences and series, probability and rotation.

Abstract

Mathematics taught in schools is often associated with the material needs of students; mathematics not only does not have to be understood in the school environment but also understood in other surrounding environments, such as culture and others. This study aimed to determine the ethnomathematics of Malay traditional floating kelong in Malang Rapat, Bintan Regency. The research method used is a descriptive qualitative method with an ethnomathematical approach. The research instruments used are observation sheets, interviews and documentation. Based on the research results presented, the author concluded, namely, the use of mathematical concepts in certain cultures and societies, such as the use of addition and subtraction in calculating the amount of wood used or the number of barrels used in floating kelongs. Making floating kelongs using basic mathematics, especially addition and subtraction operations, can be used to calculate the amount of wood used to construct floating kelongs and the number of barrels applied. Taxonomy is also applied to analyze and categorize certain elements in research, concerned with understanding how the components of floating kelong are classified or organized. The role of mathematics in identifying and calculating pesky components (materials that bring good luck or maintain security) used in floating kelongs. Ethnomathematics can also involve understanding the cultural themes underlying the use of mathematics in everyday life, such as how mathematical concepts are integrated with cultural beliefs and practices in the construction of floating kelongs.
