Efektivitas Pengembangan Media Pembelajaran Komik Berbasis Kodular untuk Kemampuan Pemahaman Literasi Matematika Siswa SDS Edustar
Get PDFStudents do not understand the basic concepts of mathematics. Even understanding mathematics lessons in class is still difficult, let alone solving mathematical literacy problems. This is due to the lack of learning media facilities that support mathematics literacy learning. So that due to a lack of understanding of the concepts of mathematics, and considers mathematics lessons are boring lessons. Therefore, it is necessary to develop flexible teaching materials that can be used in any situation to support students\u27 understanding of mathematical literacy. Thus, the researcher developed a codular-based comic learning media for students\u27 mathematical literacy comprehension skills. This study aimed to see the effectiveness of the codular-based comics learning media for the ability to understand mathematical literacy of elementary school students Edustar. This research was conducted at SDS Edustar Batam with research subjects in grades 4, 5, and 6. The data collection of this study used the results of the post-test of students on students\u27 mathematical literacy of 62.01%. So it can be concluded that the codular-based comics learning media is effectively used as a medium for learning students\u27 mathematical literacy
Analisis Kemampuan Berpikir Kreatif Matematis Siswa Kelas VIII MTs Nurus Salam Deli Tua Pada Materi Pola Bilangan
Get PDFThis study aims to analyze and describe students\u27 mathematical creative thinking skills and to find out the causes of students\u27 low mathematical creative thinking skills in number pattern material. This descriptive study uses qualitative methods that provide an overview of student\u27s creative thinking skills in solving mathematical problems. The data collection technique used is a test technique using 20 questions of an early mathematical ability test, four questions of a mathematical creative thinking ability test, and interviews. The indicators of mathematical creative thinking skills are fluency, originality, flexibility, and elaboration. Data analysis found that subjects with high, medium, and low abilities could only meet two indicators: fluency and elaboration. Subjects with high abilities were categorized into the criteria for creative thinking skills with a percentage of 62.5%. Meanwhile, students with moderate abilities are categorized into the criteria for creative thinking skills with a percentage of 50%, and students with low abilities are categorized into the criteria for less creative thinking abilities with 25%
Teori Perkembangan Piaget dan Vygotsky : Bagaimana Implikasinya dalam Pembelajaran Matematika Sekolah Dasar?
Get PDFMathematics is an important subject whose applications were widely used in life. However, many students have difficulty in learning mathematics, including elementary school students. This study aimed to examine the depth of Jean Piaget\u27s cognitive development and Lev Vygotsky\u27s sociocultural theory and their implication for mathematics learning at elementary school age. This study used a qualitative approach with the literature study method. Sources of data in the form of books, journals, and the results of previous research related to research problems. Data collection in this study was carried out using online searches. Data analysis was done by content analysis. The results of this study indicate that according to Piaget\u27s theory of cognitive development, the thinking stage of students in elementary schools was generally in the concrete operational stage. So that the recommended mathematics learning was in the form of student-centered active learning such as discovery learning and contextual learning methods. Meanwhile, based on Vygotsky\u27s sociocultural theory, he recommends cooperative and collaborative mathematics learning as well as optimizing the existence of scaffolding and social interaction in learning
Peningkatan Kemampuan Pemecahan Masalah menggunakan Model Problem Based Learning Berbantuan Video Pembelajaran Di Sekolah Dasar
Get PDFThis research uses a quantitative approach. This study aims to determine the increase in problem-solving skills using the Problem-Based Learning Model, which is better than what is taught through conventional learning assisted by Video Learning in Elementary Schools. The type of research used in this research is experimental. Data collection techniques in this study were carried out through tests, namely pre-tests and post-tests, in the form of problem-solving ability tests and observations of the learning. The pre-test was carried out before the learning took place, and the post-test was carried out after the learning took place on both experimental and control groups. This instrument consists of test questions to measure students\u27 problem-solving abilities. Data were analyzed by comparing student scores obtained from student results before and after being treated with conventional learning. The study results concluded that the obtained t-table value could be written as follows; t-table with a significance level of 5% = 1.303 < t-count = 2.076 for t-count or ha is accepted and ho is rejected. This video-based PBL model is suitable for learning mathematics in elementary schools
Analisis Spasial dan Temporal Data Kejadian Bencana Banjir dengan Model Generalized Space Time Autoregressive Integrated Moving Average (GSTARIMA)
Get PDFThe Generalized Space-Time Autoregressive Integrated Moving Average (GSTARIMA) is a model used to model time series data that exhibits spatial dependencies among its locations as well as temporal dependencies. GSTARIMA is applied in various economic contexts, including analyzing exports and imports, exchange rates, production, inflation, and rainfall. This research aims to develop the best GSTARIMA model and utilize it to forecast rainfall in the Medan Belawan District. The GSTARIMA model combines temporal and geographical aspects by adjusting parameters for each observed location. The data used in this study consists of monthly rainfall data for the Medan Belawan District, obtained from the Maritime Class II Meteorological Station in Belawan, spanning from January 2020 to December 2022. The identification of Autoregressive (AR) and Moving Average (MA) orders was performed through the analysis of the Autocorrelation Matrix (MACF) and Partial Autocorrelation Matrix (MPACF). This study employed a spatial order of 1, along with an inverse distance weighting matrix and cross-correlation normalization. Parameter estimation used the generalized least squares (GLS) method. The research results indicate that the GSTARIMA model (2,0,0) with the inverse distance weighting matrix achieved the lowest Mean Absolute Percentage Error (MAPE) rate, specifically at 1.0170. Thus, this model is considered the best for forecasting rainfall in the Medan Belawan District
