Instructional Skills and Work-Based Performance of Junior High School Mathematics Teachers: Basis for Strategic Intervention Plan

Mathematics education plays a vital role in developing learners' critical thinking, problem-solving, and analytical skills. Despite the implementation of various instructional innovations and educational reforms, improving students' mathematics achievement remains a continuing challenge. This highlights the need to strengthen teachers' instructional competencies, as effective teaching is a key factor in promoting meaningful learning and improving educational outcomes.

In response to this gap, this study examined the instructional skills
