Abstract

Multiplication fluency remains a persistent challenge for many Filipino learners, yet community-based evidence on low-cost supplementary interventions is limited. This study examined whether a six-week Trachtenberg speed math intervention was associated with improved multiplication performance among learners aged 8 to 13 years in three local communities in Danao City, Philippines. The study used a one-group pretest-posttest quasi-experimental pilot design conducted during a community-based numeracy intervention. Paired scores from 135 participants were analyzed using paired-samples t-tests, mean gains, 95% confidence intervals (95% CI), and within-subject effect sizes (dz). Scores increased significantly in Maslog from 27.31 to 49.82, in Sabang from 32.68 to 49.84, and in Taytay from 31.91 to 48.78 (all p

Abstract

Faculty promotion in Philippine state universities depends on performance in instruction, research, extension, and professional development, yet institutions often lack evidence on whether faculty are equally prepared across these domains. This study examined perceived competence and developmental needs among regular faculty members at a large, multi-campus Philippine state university. Using a descriptive-analytical cross-sectional design, all 824 regular faculty members were invited to an online survey; 346 responded, and 300 valid responses were analyzed. Descriptive statistics, association tests with false discovery rate adjustment, and thematic analysis of open-ended responses were used. Not applicable responses were excluded from domain score denominators to avoid penalizing faculty for non-applicable promotion indicators. Findings showed uneven competence across the four domains. Instruction remained the strongest area, while research was the most constrained domain, with low levels of indexed publications, scientific presentations, and intellectual property outputs. Qualitative themes highlighted unequal access to opportunities, research support needs, workload pressures, funding constraints, and field-alignment concerns. Promotion-oriented faculty development should therefore prioritize structured research mentoring, protected time, support for converting outputs, and equitable access mechanisms across campuses.
