  1. Development and Validation of E-SelfIMo: E-Learning Self-Directed Interactive Module in Earth Science.Nestor Lasala Jr - 2023 - Recoletos Multidisciplinary Research Journal 11 (1):85-101.
    This study developed and validated E-learning Self-directed Interactive Modules (E-SelfIMo) for Earth Science. The study employed Research and Development method, using the Borg and Gall development procedure, in creating eight e-modules using Kotobee software, evaluating them by experts and students, and determining their effectiveness in terms of students' conceptual understanding. Experts agreed that E-SelfIMo met the DepEd standards for non-printed learning materials, and students attested to their high validity in content, format, and usefulness. Pretest and posttest results for the effectiveness (...)

  2. The 360˚ View: Contextualized Virtual Reality Tours as Innovative Teaching Tool in Ecology for Elementary School Students.Rubert James Gestiada, Frank Joseph Tisoy & Nestor Lasala Jr - 2025 - Journal of Basic Education Research (1):35-48.
    Purpose of the Study. This study aims to develop and validate Contextualized Virtual Reality Tours as instructional materials for teaching ecology concepts to elementary students, focusing on enhancing students' conceptual understanding of ecological relationships and environmental awareness in a local context. Methodology. The study employed a descriptive-developmental research design and used the ADDIE model to create Contextualized Virtual Reality Tours. Tools included a 64MP mobile camera for video production, AI-generated voice narration, and a 4-point Likert scale assessment for validation. Data (...)

  3. Effects of Game-Based Activities on Student's Social Skills and Attitudes toward Learning Science.Nestor Lasala Jr - 2024 - Recoletos Multidisciplinary Research Journal 12 (1):181-194.
    This study evaluated the effectiveness of four game-based activities (GBAs) in teaching ecosystems to Grade 7 Biology students. Involving 69 students (34 control, 35 experimental), the quasi-experimental study used a mixed-methods approach. The researcher utilized a static-group comparison design for the quantitative phase and a thematic analysis for the qualitative phase. Quantitative analysis revealed significant improvements in the experimental group's social skills (p<0.05; Cohen’s d = 0.63) and conceptual understanding (p<0.05; Cohen’s d = 0.86). Descriptive statistical analysis also suggests that (...)

    BEsMART: Board Examinations Mobile Application Reviewer for Pre-Service Science Teachers using Space Repetition and Hypercorrection.Nestor Lasala Jr, Jonel Prado, Noemi Doringo & Jhonner Ricafort - 2025 - Pakistan Journal of Life and Social Sciences 23 (2025):7274-7290.
    This study developed and validated BEsMART, a mobile review application for pre-service science teachers preparing for the Licensure Examination for Teachers (LET). Addressing challenges such as high review costs, inconsistent study habits, and concept retention difficulties, BEsMART integrates spaced repetition for memory retention and hypercorrection techniques to correct misconceptions. Other features include questionbased drills, multimedia resources, instant feedback, and progress tracking. A mixed-method research design was employed, combining ISO/IEC 25010 standards, the U.S.E. Questionnaire, and qualitative feedback from 9 experts and (...)

  5. Effectiveness of Brain-Based Learning Toward Improving Students’ Conceptual Understanding: A Meta-Analysis (17th edition).Aaron Funa, Jhonner Ricafort, Frances Grace Jetomo & Nestor Lasala - 2024 - International Journal of Instruction 7 (1):361-380.
    This study explores the effectiveness of brain-based learning (BBL) as a pedagogical approach to address the challenges of poor conceptual understanding, which may have worsened due to the COVID-19 pandemic aftermath. In this meta- analysis, 14 studies qualified using the Publish or Perish software and the Preferred Reporting Items for Systematic Reviews and Meta-analyses. Statistical analysis conducted using Comprehensive Meta-Analysis (CMA) Version 4 software by Biostat, Inc. Based on the results, the overall effect size (ES = 3.135) indicates that the (...)

  6. EDUTainment: Effectiveness of Game-based Activities in Teaching Ecosystem Topics (2nd edition).Nestor Lasala Jr - 2023 - Recoletos Multidisciplinary Research Journal 11 (2):69-83.
    This study utilized four game-based activities (GBAs) developed by the researcher to determine their effectiveness in teaching Ecosystem topics for Grade 7 Biology in terms of (1) conceptual understanding and (2) nature of engagement. This quasi-experimental study used a mixed-method approach. Pre-test and post-test results show that the integration of GBAs in the lessons significantly improved students’ academic performance in terms of conceptual understanding. Students' reports and teachers' observations also indicated that GBAs could enhance students’ engagement in their lessons and (...)
