Abstract

Subitizing, the ability to rapidly and accurately recognize small quantities of objects without counting, has become a primary focus in developing numeracy understanding in early childhood. The research uses a qualitative approach with literature study techniques. The study aims to provide a comprehensive overview of the concept of subitizing, learning trajectories, and recommendations for teaching it to young children, as well as concrete examples from research involving multidisciplinary approaches. The findings indicate that current research explores various aspects of subitizing, ranging from effective teaching strategies to learning trajectories appropriate for children’s developmental stages. Effective subitizing instruction includes the use of relevant number concepts in everyday interactions, practicing naming small collections of objects with numbers, and repeated experiences in recognizing and naming groups of objects. Subitizing learning trajectories encompass developmental processes and the creation of task-supportive environments, ranging from unconscious number understanding to the ability to recognize quantities up to 10 objects. Various research outcomes also highlight the application of subitizing in technology development, such as subitizing games to enhance children’s mathematical abilities and assistive software for children with dyscalculia. Studies in psychology and health fields reveal the complexity of the relationship between subitizing and cognitive functions, such as in children with specific conditions like Cerebral Palsy or brain injuries. With a multidisciplinary approach, current research continues to expand understanding of the benefits of subitizing and its implications in various contexts, from education to health, aiming to enhance children’s learning and well-being holistically.

Abstract

This research project was conducted to investigate the mathematical aspects, specifically focusing on two-dimensional geometry concepts found in the architectural design of the Tuatunu Grand Masjid, which aimed to integrate these research findings into the mathematics education curriculum. Utilizing a descriptive qualitative methodology from an ethnographic standpoint, information was collected through interviews with two takmir (masjid administrators), as well as through direct observation and documentation. The primary data collection method was direct interaction with participants, which could benefit from further explanation to clarify the specific types of interactions conducted. The analysis process followed Spradley"™s framework, encompassing domain analysis, taxonomy, componential analysis, and identification of cultural themes. The study"™s outcomes highlighted the presence of a variety of geometric shapes within the Tuatunu Grand Masjid, including triangles, quadrilaterals, pentagons, polygons, and circles. These findings suggest that the masjid can serve as a valuable resource for developing educational materials, including worksheets and textbooks, that are grounded in ethnomathematics. By incorporating the architectural features of the masjid into mathematics education, educators can offer students a tangible and practical context for learning two-dimensional geometry, enhancing their understanding and engagement with the subject matter.

Abstract

Micro, Small, and Medium Enterprises (MSMEs) are one of the main drivers of national economic growth, playing a crucial role in establishing a healthy economic structure and performance. The government demonstrates its support for MSME actors through financing initiatives, one of which is provided by Permodalan Nasional Madani (PNM), which since 2015 has offered capital loans to underprivileged women entrepreneurs. This study aims to determine the influence of business capital financing and product innovation on the business development of communities in Lubuk Besar District, particularly the clients of PNM Mekar Syariah. This research uses a quantitative approach with primary data. The population consists of 2,903 individuals, with 97 respondents selected using a random sampling technique. Data analysis was conducted through validity and reliability tests, classical assumption testing, multiple regression analysis, and hypothesis testing with the assistance of SPSS version 30.0. The results of the study show that partially, business capital financing has a significant effect on business development (significance < 0.001; t-count = 3.488 > t-table = 1.985). Product innovation also shows a significant influence (significance = 0.009; t-count = 2.672 > t-table). Simultaneously, both variables significantly affect business development (F-count = 25.317 > F-table = 3.09). The contribution of these two variables to business development is 35%, while the remaining 65% is influenced by other factors not examined in this study.

Abstract

This research aims to analyze the results of the application of Blended Learning with reference to the Project-Based Learning (PjBL) model. Blended Learning and PjBL can be packaged as a learning model, namely Project-Based Blended Learning (PjB2L). The design of learning activities with the help of e-campus media is used to measure its impact on student learning outcomes in Statistics courses. The main focus of the research describes two main things, the description of the application of statistics lectures with the PjB2L model and the results of statistical tests on differences in learning outcomes obtained. Quasi-experimental research was designed to compare student learning outcomes in experimental classes (with the PjB2L model) and control classes (conventional/blended direct learning). 43 students were involved in this study which was divided into two classes, namely the control class which included 20 students, and the experimental class which involved 23 students. In addition, on data analysis technique, analysis of covariance (ANCOVA), was used to compare the results of the control group and the experimental group, with the covariance variable being the pre-test results (initial knowledge). The results showed significant differences. The difference shown in this study leads to the support of the experimental group's better learning achievement.
