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.

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: 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: Every academic institution aims to produce competent and highly qualified graduates who can compete locally and globally. The graduates' success in gaining and maintaining employment mirrors the quality of instruction, training, and preparation they have received in school. Tracer studies are important ways of determining graduates' employment status, which may serve as a basis to ascertain the relevance and effectiveness of the program. This study aimed to trace the Master of Science in Teaching Physics (MST Physics) graduates of the University of Northern Philippines. Thirty-six graduates served as respondents. The instrument used was a modified Graduate Tracer Study Questionnaire of the Commission on Higher Education. Data were gathered online using Google Forms, and analyzed using frequency, percentage, and mean. Findings of the study show that all of the graduates are married. There were more female than male graduates. Most of the graduates are from the province of Ilocos Sur, and a majority are BS Physics graduates with honors. The top reasons for enrolling in the program were prospects for career advancement, availability of course offerings in the institution, and a strong passion for the profession. All respondents are currently employed and hold permanent positions in the local education sector. In terms of the competencies they learned from the program, the graduates found critical thinking, problem-solving, and communication skills most helpful in their employment. The respondents averred that all the program outcomes were very highly attained. To improve the program, the graduates suggested the improvement of the curriculum and instruction, facilities, and co-curricular activities.

Abstract: Mathematics education should become holistic, relevant, and connected with learners’ everyday lives, including their culture. This qualitative study aimed to explore the integration of the Ilokano culture in Teaching Mathematics at the University of Northern Philippines (UNP) in Vigan City, Ilocos Sur, through a case study qualitative research approach. Findings showed that there is an integration of Ilokano culture in teaching mathematics in UNP. Ilokano culture is primarily used to motivate students or introduce new concepts. The integration of Ilokano culture establishes connections between the faculty and their students and their cultural heritage. The faculty participants also used culture-related examples and problems to emphasize mathematical concepts. Various elements of Ilokano culture are embedded in the teaching-learning process, the language, practices, values, known figures, landmarks, and crafts included. A culture-responsive structure exists in UNP as evidenced by its vision, mission, and developmental goals, which stress preserving and promoting its rich cultural heritage. Difficulties in Ilokano culture integration include inadequacy in knowledge about culture and formal preparation in culture integration and culture-relevant resource materials. The integration of culture into the mathematics curriculum makes it more relevant to the students; thus, it is recommended that teachers design learning experiences in mathematics classes based on the students' cultural background.
