Canonical JSON (keys sorted, no spaces, UTF-8). Its SHA-256 is the hash on chain. The abstract here is gemini shortened, not the author's own text.
{"abstract":"This study determined the effects of using contextualized materials on the development of Most Essential Learning Competencies in Araling Panlipunan among selected Junior High School students in a Private School in Gumaca, Quezon. The research profiled 100 respondents by age, sex, and grade level, using a descriptive method and quota sampling. Most respondents were 14-15 years old, with females outnumbering males, and represented Grades 7, 8, 9, and 10. Findings indicated strong agreement on the effects of contextualized materials in developing competencies across several areas: recall (average mean 4.15, interpreted as Agree), association (average mean 4.16, interpreted as Agree), use of multiple channels (average mean 4.29, interpreted as strongly agree), and interest and motivation (average mean 4.23, interpreted as strongly agree). The Kruskal Wallis H-test revealed no significant difference in perceived effects when respondents were grouped by age, sex, or grade level. Recommendations included training for administrators, parental monitoring, teacher-provided activities, student practice, and future parallel studies focusing on contextualized materials for successful internalization.","abstract_source":"gemini_shortened","authors":["Charlene Nuez","Maria Celerina Oreta","Melchor Espiritu","Rochelle Leonor","Donata Cadag"],"date":"2025-06-03","doi":"10.70838/pemj.390404","id":5425,"issue":4,"journal":{"issn":"2822-4353","name":"Psychology and Education: A Multidisciplinary Journal"},"pdf_sha256":"9ff8f5a19289fefe569861996234af662e3f2a0e49ea0177cf94a0722103fcfd","schema":"scimatic-article/1","title":"Using Contextualized Materials in the Development of Most Essential Learning Competencies of Selected Junior High School Students in a Private School in Gumaca, Quezon","volume":39}
