    Development and Validation of the Mathematics Attitude Scale (MAS) for High School Students in Southern Philippines
    with Elmark Facultad
    International Journal of Innovation, Creativity and Change 8 (2): 146-168. 2019.
    This study developed an instrument that measures the attitude of Filipino high school students towards mathematics, with reliable predictors and factors. Using the responses of 300 high school students from Zamboanga Sibugay, the validity and reliability of the Mathematics Attitude Scale (MAS) was tested using Exploratory Factor Analysis (EFA) and reliability analyses. The EFA showed that four-factor structures of the instrument, regarding the mathematics attitude for high school students, expla…Read more

    Addressing difficulty in Calculus limits using GeoGebra
    with Villa Althea Yap and Juvie Sebial
    Science International Lahore 34 (5): 427-430. 2022.
    This paper aims to address the difficulties of high school students in bridging their computational understanding with their visualization skills in understanding the notion of the limits in their calculus class. This research used a pre-experimental one-group pretest-posttest design research on 62 grade 10 students enrolled in the Science, Technology, and Engineering Program (STEP) in one of the public high schools in Zamboanga del Sur, Philippines. A series of remedial sessions were given to h…Read more

    A Structural Equation Model on Pro-Social Skills and Expectancy-Value of STEM Students
    with Joy Mirasol
    European Journal of Educational Research 12 (2): 967-976. 2023.
    The objective of the study was to develop a structural model that explores the relationship between Mathematics Performance and students’ self-regulated learning skills, grit, and expectancy-value towards science, technology, engineering and mathematics (STEM). The research collected survey data from 664 senior high school students from 17 STEM high schools, and conducted a covariance-based structural equation modeling (SEM) analysis. The results of the SEM analysis indicate that the Re-specifie…Read more
