ON EVEN-TO-ODD MEAN LABELING OF SOME TREES Leomarich F Casinillo
Journal of Fundamental Mathematics and Applications (JFMA) Vol 4, No 1 (2021)
Publisher : Diponegoro University

Let G=(V(G), E(G)) be a connected graph with order |V(G)|=p and size |E(G)|=q. A graph G is said to be even-to-odd mean graph if there exists a bijection function phi:V(G) to {2, 4, ..., 2p} such that the induced mapping phi^*:E(G) to {3, 5, ..., 2p-1} defined by phi^*(uv)=[phi(u)+phi(v)]/2 for all uv element of E(G) is also bijective. The function is called an even-to-odd mean labeling of graph . This paper aimed to introduce a new technique in graph labeling. Hence, the concepts of even-to-odd mean labeling has been evaluated for some trees. In addition, we examined some properties of tree graphs that admits even-to-odd mean labeling and discussed some important results.

ANOTHER LOOK AT A POLYNOMIAL SOLUTION FOR ALTERNATING POWER SUMS Leomarich F Casinillo
Journal of Fundamental Mathematics and Applications (JFMA) Vol 5, No 1 (2022)
Publisher : Diponegoro University

This paper aims to provide a new general explicit polynomial solution on power sums of consecutive positive integers under alternating signs. Moreover, it examines the solution under odd and even number of terms in the series and provides some examples.

Modelling Experiences And Its Factors In General Mathematics: The Case Of Grade 11 Students Leomarich F Casinillo; Emily L Casinillo
Indonesian Journal Of Educational Research and Review Vol. 3 No. 2: July 2020
Publisher : Universitas Pendidikan Ganesha

Student’s experiences in learning plays an essential role in producing quality academic achievement. This study aimed to develop multiple regression models on the students’ experiences in learning mathematics in regards to its influencing factors. A simple random sampling of 112 grade 11 students in the first semester of school year 2018-2019 from Visayas State University were used as the respondents of this study. Result of the study reveals that grade 11 students’ learning experience in general mathematics is challenging and logical. However, it is found out that it is satisfying and rewarding since it develops their critical thinking and decision making in real life. The number of hours in studying and studying with internet positively influence the students’ learning experience in mathematics. It is also revealed that STEM students are more fond learning mathematics compare to non-STEM students. Furthermore, result also shows that a conducive learning environment and religious activities in the campus helps the students to have a peaceful and positive learning experience.

The Impact of Broken Homes on Students’ Academic Performance Leizl F Abrantes; Leomarich F Casinillo
Indonesian Journal Of Educational Research and Review Vol. 3 No. 3: October 2020
Publisher : Universitas Pendidikan Ganesha

This study aimed to analyze the influence of problems encountered from broken homes on academic performance among senior high students. This study adopted a Descriptive-Correlational design. A constructed survey questionnaires were given to 168 students identified through purposive sampling for the response of the problems encountered of being in a broken home. Through simple random sampling, another 168 students from two-parent homes were used as a comparison. Secondary data such as grade point average was taken from the School Registrar. Descriptive statistics were employed to summarize the different variables and Spearman correlation was undertaken to identify the significant relationship between variables. Results revealed that there is no significant difference between the academic performance of students from single-parent homes and two-parent homes. It is also found out that problems encountered by students from single parent homes does not affects their studies and learning attitudes. With the aid of Spearman Rho Correlation Coefficient, it denotes a highly significant relationship between problems encountered by the students and their academic performance. This suggest that students are considering their problems as motivation to strive hard in their studies in order to become successful.
