Abstract:Student engagement, according to educators and numerous researchers, is one of the most important factors in being academically successful. The study determined the level of engagement in mathematics of the first-year students of the University of Northern Philippines. The study's findings show that the respondents are predominantly males, from public high schools, and attained fair grades. The respondents have a fair level of engagement in mathematics. The respondents' engagement in mathematics is associated with their profile. An action plan was formulated. Based on the study's results, it is recommended that other student-related factors and dimensions of student engagement be considered in similar studies, and the action plan must be implemented.

Abstract:Crime such as robbery has been identified as one of the socioeconomic problems across the world, which adverse social, economic, and family conditions have caused. Using discriminant analysis, this study proposed a model for classifying and predicting countries with low and high robbery rates. Robbery rates in 2018 of 42 countries across the world have been extracted from United Nations Office on Drugs and Crime as the dependent variable. Meanwhile, the independent variables included the unemployment rate, average household size, and poverty index. The study originally classified 32 countries with low and 10 with high robbery rates. Pretesting was employed, and the results showed that all the assumptions for discriminant analysis were fulfilled. Using standardized beta and Wilk's Lambda, the average household size is the best predictor variable, while the unemployment rate is the least predictor variable. The overall prediction function model is significant. The classification results by discriminant analysis algorithm for groups with low and high robbery rates show that the proposed model correctly predicts 78.6% of the robbery rates of countries based on the three characteristics, such as their unemployment rate, average household size, and poverty index

Abstract:This study presents an experimental analysis of water jet dynamics using an improvised jet impact apparatus. The research encompassed the design, construction, and testing of the apparatus to evaluate its performance. Testing involved determining and comparing theoretical and experimental impact forces under various experimental setups. These setups included different masses (70.0 g, 100.0 g, 150.0 g) and target vanes with varied angles of impact (90°, 29.5°, 180°). The target vanes were designed with flat, conical, and hemispherical surfaces. The results indicated that the improvised apparatus achieved an overall percentage error of 17.39% in determining impact forces. Among the configurations, the hemispherical target vane combined with a 100 g mass-produced the most accurate results, with a 7.04% error. The highest percentage error of 31.6% occurred with the flat target vane and a 70 g mass. These findings suggest that while the apparatus can yield precise results under optimal conditions (e.g., hemispherical vane and 100 g mass), it may produce less accurate measurements in other configurations. Despite its limitations, the improvised jet impact apparatus demonstrates utility as a teaching and learning tool for exploring fluid dynamics, particularly the behavior of water jets. It provides an accessible means of demonstrating fundamental concepts, even if not suited for experiments requiring high precision. Overall, the apparatus serves as a valuable resource for introducing students to the principles of jet impact and fluid dynamics.
