Development of Laboratory Manual as Supplemental Materials in Teaching Technical Vocational Education Program

This study aimed to develop laboratory manual as supplemental materials in teaching technical vocational education program in the College of Education, Technical Vocational Education Department for the academic year 2024-2025. This study employed a mixed-method approach using descriptive, developmental, and experimental designs guided by the ADDIE model (Analysis, Design, Development, Implementation, Evaluation). It involved diagnostic testing, bibliometric review, and quasi-experimental procedures to develop and validate a TESDA-aligned laboratory manual for Civil Technology. Data was gathered from students, teachers, curriculum experts, and academic heads using validated instruments, with results analyzed through average weighted mean and standard deviation. The results indicate that the study identified least learned competencies in Civil Technology II and used these to develop a TESDA-aligned laboratory manual. Bibliometric insights shaped its structure, and experimental results confirmed its effectiveness in improving student learning, earning strong support from students, teachers, and academic heads. It is strongly recommended to may consider adopting and integrate the TESDA-aligned laboratory manual into the Industrial Arts curriculum to strengthen hands-on learning and improve student competency.
