Abstract

Numeracy is associated with students' self-efficacy, and it is crucial to examine the elements affecting numeracy proficiency, particularly behavior, including self-efficacy. A lack of research amalgamates both dimensions, encompassing the reciprocal impacts and the impact of contextual factors like gender and educational background. This study seeks to ascertain the influence of mathematics self-efficacy aspects on numeracy among elementary school teacher education students in the Yogyakarta region. The sampling method employed was non-probability sampling, specifically utilizing a convenience sampling methodology with a sample size of 215. The data analysis employed Structural Equation Modeling – Partial Least Squares (SEM–PLS). This study identifies the "strength" dimension of self-efficacy in numeracy as the most influential factor affecting an individual's numeracy skills. Frequent exposure to consistent and relevant learning experiences enhances students' confidence in decision-making when confronted with numeracy challenges. The "strength" of students' mathematics self-efficacy can be affected by various aspects, such as pleasant learning experiences, social support, and achievements in solving mathematical obstacles. Students who frequently confront and successfully resolve mathematical issues experience increased confidence as they trust in their capacity to tackle analogous tasks in the future. If this conduct is consistently exhibited during the student's study period, the numeracy component may enhance and serve as a valuable resource for future teachers.

Abstract

This survey investigates the application of the Data Distribution Service (DDS) within the domains of edge and fog computing architectures. DDS, a middleware architecture conceived by the Object Management Group (OMG), offers robust publish-subscribe functionalities characterized by low latency, high reliability, and scalability attributes, rendering it particularly suitable for real-time data dissemination in distributed systems. The paradigms of edge and fog computing, recognized for their capability to process data in proximity to its origin, leverage the functionalities of DDS to tackle issues such as latency minimization, bandwidth enhancement, and resource efficiency. The research meticulously evaluates the significance of DDS in facilitating scalable and reliable communication for applications spanning industrial automation, healthcare, and smart urban environments. It delineates pivotal implementation obstacles, including resource limitations, interoperability challenges, and security concerns within decentralized frameworks. Mitigation strategies such as lightweight DDS protocols, adaptive Quality of Service (QoS) policies, and artificial intelligence-driven optimizations are underscored to address these constraints. Employing PRISMA guidelines, a total of 16 peer-reviewed studies were scrutinized to respond to research inquiries centered on the role of DDS in edge and fog computing, associated technical hurdles, implications for QoS, and emergent trends. The results underscore the capacity of DDS to converge with cutting-edge tech-nologies such as 5G, blockchain, and digital twins, thereby influencing the evolution of intelligent distributed systems. This survey enhances the existing comprehension of DDS's transformative capabilities within contemporary computing architectures, offering valuable insights into best practices and prospective avenues for the optimization of edge and fog computing environments.

Abstract

This study aims to: 1) Determine the implementation of the Snowball Throwing learning method in the subject of Mathematics with numbered material. 2) Increase the learning activity of students through the Snowball Throwing learning method in the Mathematics subject of numbered numbers. 3) Increase the critical thinking of students through the Snowball Throwing learning method in the subject of Mathematics of numbered material. This research is a Class Action Research (PTK) with a Kemmis and Taggart spiral model consisting of four stages, namely Planning, Action, Observation, and Reflection. The research subjects were 20 students in grade IV of SD Negeri Gedongkiwo Yogyakarta. Data was collected through observation, questionnaires, tests and documentation, then analyzed quantitatively and qualitatively descriptive. The validity of the data is carried out by examining credibility using triangulation techniques. The results of the study showed a significant increase in the activeness of learning and critical thinking in mathematics using the Snowball Throwing method. In the aspect of learning implementation, the percentage increased from 64% (poor category) in the first cycle of the initial meeting. to 71% (quite good in the final meeting. In the second cycle of the initial meeting, the implementation increased to 88% (good) and reached 94% (very good) at the final meeting. The learning activity of students also increased, from pre-cycle by 51% (good), then increased in cycle I to 54% and 68% (good), and experienced an increase in meaning in cycle II to 77% and reached 89% (very good). The students' critical thinking skills also developed, as seen from the overall completeness of 40% of pre-cycle students who obtained an average score of KKM, increased in cycle 1 from 55% to 65%, and in cycle II from 75% to 90% with 18 students who obtained an average score of KKM.
