{"abstract":"The study aimed to determine the extent of school heads’ mentoring practices on teachers’ instructional performance of select public elementary school teachers in Sugbongcogon District, Division of Misamis Oriental. Results show that school heads’ mentoring practices are exceptionally high. Teachers always performed their instruction functions, and there was a moderate correlation between school heads’ mentoring practices and teachers’ instructional performance. It was recommended that school heads should continue their mentoring activities to teachers to improve teachers’ instructional performance, and teachers are stimulated to provide appropriate instructional activities to students and design interesting lesson presentations to form relationships and improve students’ learning outcomes.","abstract_source":"original","authors":["Bai Sahara Umbal"],"date":"2026-02-26","doi":"10.70838/pemj.520707","id":7255,"issue":7,"journal":{"issn":"2822-4353","name":"Psychology and Education: A Multidisciplinary Journal"},"pdf_sha256":"e516010fcc34317399b63caa3c8ebd93f91e1e89d15634440318fe674f058425","schema":"scimatic-article/1","title":"School Head Mentoring the Mentors Practices and the Teachers’ Instructional and Work Performance","volume":52}
