Abstract (English)

This study aimed to enhance students’ science process skills (SPS) through the development and validation of SPS Proficiency Assessment (SPS-PA) and SPS-Enhanced Science Instructional Framework (SPS-ESIF). The study also identified the SPS Development Proficiency level of the students using the SPS-PA Rasch analysis results. A mixed-methods research design was employed, integrating quantitative and qualitative approaches to ensure the validity, reliability, and practical applicability of the instruments. The validation process included expert review, pilot testing, exploratory factor analysis, CTT and Rasch analysis, followed by full-scale implementation. The results provided empirical evidence supporting the psychometric soundness of the developed tools and enabled the identification of students’ SPS Developmental Proficiency levels. Findings from the study informed the development of a data-driven strategic action plan  through the SPS-ESIF, which emphasize the integration of SPS into curriculum, instruction, and assessment. The framework promotes inquiry-based learning, supports differentiated instruction, and enhances teachers’ capacity to implement SPS-focused pedagogies. Overall, this study contributes to science education by providing a comprehensive and standardized system for assessing and developing science process skills. The findings offer practical implications for improving instructional practices and support efforts to strengthen students’ scientific literacy and readiness for STEM-related careers.

Abstract (Filipino)

Layunin ng pag-aaral na ito na mapahusay ang science process skills (SPS) ng mga mag-aaral sa pamamagitan ng pagbuo at beripikasyon ng SPS Proficiency Assessment (SPS-PA) at SPS-Enhanced Science Instructional Framework (SPS-ESIF). Tinukoy rin ng pag-aaral ang antas ng SPS Development Proficiency ng mga mag-aaral gamit ang mga resulta ng pagsusuring Rasch ng SPS-PA. Gumamit ang pag-aaral ng mixed-methods research design na pinagsama ang kwantitatibo at kwalitatibong pamamaraan upang matiyak ang balididad, reliability, at praktikal na gamit ng mga instrumento.

Kasama sa proseso ng beripikasyon ang pagsusuri ng mga eksperto, paunang pagsubok, exploratory factor analysis, CTT at Rasch analysis, at kasunod nito ang malawakang implementasyon. Nagbigay ang mga resulta ng empirikal na ebidensiyang sumusuporta sa pagiging matatag ng mga psychometric na katangian ng mga nabuong kasangkapan at nagbigay-daan sa pagtukoy ng antas ng SPS Developmental Proficiency ng mga mag-aaral.

Ang mga natuklasan sa pag-aaral ay naging batayan sa pagbuo ng isang data-driven strategic action plan sa pamamagitan ng SPS-ESIF, na nagbibigay-diin sa integrasyon ng SPS sa kurikulum, pagtuturo, at pagtataya. Itinataguyod ng balangkas ang inquiry-based learning, sumusuporta sa differentiated instruction, at pinauunlad ang kakayahan ng mga guro sa pagpapatupad ng mga pedagohiyang nakatuon sa SPS.

Sa kabuuan, nakapag-aambag ang pag-aaral na ito sa edukasyong pang-agham sa pamamagitan ng pagbibigay ng komprehensibo at estandardisadong sistema para sa pagtataya at pagpapaunlad ng science process skills. Nagbibigay ang mga natuklasan ng praktikal na implikasyon sa pagpapabuti ng mga gawaing panturo at sumusuporta sa pagpapatibay ng scientific literacy ng mga mag-aaral at kanilang kahandaan para sa mga karerang may kaugnayan sa STEM.
