ABSTRACT

This study aims to evaluate the validity and reliability of the physical education (PE) teaching implementation instrument in secondary schools. A valid and reliable instrument is a fundamental basis for ensuring data accuracy and teaching effectiveness in fostering an active lifestyle among students. This study employs a quantitative research design in the form of a survey involving physical education teachers. The instrument used is a structured observation checklist covering four main constructs: implementation of teaching strategies, use of resource materials, use of facilities, and implementation of assessment. The content validity process involved two phases: a review by six experts in the field of Physical Education and a second-phase evaluation by PE teachers. The reliability of the instrument was analyzed using the Kuder-Richardson 21 (KR-21) formula and inter-rater reliability. Results from the pilot study showed high reliability coefficients for all dimensions, with values ranging from 0.600 to 0.985, while the inter-rater reliability value for teaching strategies reached 91.7%. The research findings conclude that this instrument has a satisfactory level of validity and reliability for measuring the PE teaching process systematically. The implications of the study suggest this instrument as a standardized evaluation tool to help schools identify the strengths and weaknesses of teacher instruction while supporting continuous professional development.

Keywords: Validity, Reliability, Physical Education, Structured Observation, Teaching Instrument.
