Teaching experience is the key to becoming effective in imparting knowledge to students. This study aims to develop regression models to determine the various factors of teaching experiences among high school educators. A cross-section of teachers in a Vocational School in Hilongos, Leyte, Philippines was considered as participants in this study. Some descriptive measures and ordinary least square (OLS) regression were employed to describe and make inferences in the survey data, respectively. Results revealed that teachers are" very satisfied" in their (...) teaching experiences on how routinely, challenging, enjoyable, and rewarding their job is. On the other hand, they are" satisfied" with how creative and logical they are in their teaching career. In addition, it is revealed that there are factors that significantly influence the teachers' experiences such as age, gender, civil status, educational attainment, income, room facilities, school compound, leisure, social relationships, and health. Hence, good compensation, support from the government, a conducive school environment, and health benefits for the teachers' hard work and dedication to their job will result in positive teaching experiences. Furthermore, relaxation and health activities, vacation, and good vibes from other teachers result to feel comfortable and confident in teaching. (shrink)

We investigate the algebraic structures of square grid graphs and obtain isomorphism theorems.

In this study, the learning experience and its cognitive factors of Mathematics among senior high school students of Visayas State University were investigated using a correlational research approach. A complete enumeration of 222 grade 11 and 12 senior high students in the second semester of school year 2018-2019 were used as the participants of the survey. Using a developed structured questionnaire, a primary data was employed. Results showed that the mathematics attitude of students influence their learning experience and academic performance. (...) Mathematics anxiety has a negative effect on the students learning experience especially for females. However, mathematical resilience locates itself in a positive psychology which addresses mental wellness and makes the students positively perceived that mathematics is interesting even if it is challenging. Also, results revealed that senior high school students are mostly visual learners in mathematics, which implies that students practice visualizing or pictures numbers/equations and other concepts in their mind. Furthermore, it can be gleaned that an academic performance is not just derived from study habits but to their motivation and interest in mathematics. (shrink)

This paper aims to construct a new formula that generates a generalized version of congruent numbers based on a generalized version of Pythagorean triples. Here, an elliptic curve equation is constructed from the derived generalized version of Pythagorean triples and congruent numbers and gives some new results.

A set D subset of V(G) is a dominating set of a graph G if for all x ϵ V(G)\D, for some y ϵ D such that xy ϵ E(G). A dominating set D subset of V(G) is called a connected dominating set of a graph G if the subgraph <D> induced by D is connected. A connected domination number of G, denoted by γ_c(G), is the minimum cardinality of a connected dominating set D. The triple repetition sequence denoted by (...) {S_n:n ϵ Z+} is a sequence of positive integers which is repeated thrice, i.e., {S_n}={1,1,1,2,2,2,3,3,3, ...}. In this paper, we construct a combinatorial explicit formula for the triple repetition sequence of connected domination numbers of a triangular grid graph. (shrink)
