Abstract

Understanding mathematical concepts plays a crucial role in students achieving favorable learning outcomes. However, there remains room for improvement in students' grasp of these concepts. The main objective of this research was to assess how effective the probing prompting learning model is in improving students' understanding of mathematical concepts. This research employed the quantitative approach with the experimental method. Used tests, observations, and questionnaires to collect the data. The study included 25 students in the experimental group and 26 students in the control group. The findings showed: 1) The average percentage of teacher activity was 96.30% (“very good” category); 2) The t-test analysis findings showed a significant difference in the enhancement of understanding of mathematical concepts between students exposed to the probing prompting learning model (high category) and those using conventional learning approach; 3) Students responded positively to the probing prompting learning model, as evidenced by their attitude. In conclusion, this study suggests that the probing prompting learning model can serve as an effective alternative for facilitating learning and improving students' understanding of mathematical concepts.

Abstract

In today's digital landscape, collaborative work in real-time is on the rise, allowing individuals to connect across different locations through applications facilitated by client-server architecture, enabling users to access and work on the same project simultaneously. However, clients' simultaneous access and modifications to the database can result in data inconsistencies, underscoring the importance of concurrency control. Managing concurrent transactions can introduce complexities and potentially adversely impact server performance. Object caching emerges as a viable solution as an alternative approach to handling transaction traffic. Extended Serial Graph-Validation Queue (Extended SG-VQ) is a control concurrency scheme that operates within the client-server architecture framework and incorporates object caching. The cache component implements a queue-based validation algorithm as part of its validation process. At the same time, the server-side employs a graph-based validation algorithm with locking strategies. Through a series of hypothetical transaction scenarios across three cases, this study validates the effectiveness of the Extended SG-VQ, demonstrating its ability to utilize serial graphs, resolve conflicts, and identify cyclic patterns.
