Abstract:
Technology application in the 21st Century teaching and learning setting substantially promotes quality education. The study determined the acceptability and efficiency of the developed lecture demo video as a learning material in teaching Grade-12 EIM in selecting electrical materials and supplies and their specifications. The analysis sought to investigate the outcomes of the assessment rating of the prepared lecture-demo video and the impact of implementation. Teacher experts, student experts, and regular students from secondary schools in Surigao Del Sur Division were the study subjects. The study's tool was the DepEd standard evaluation rating tool for non-print materials obtained from the Surigao del Sur Division Learners Resource Management and Development Office, the developed lecture demo video, and the pretest and posttest questionnaires adopted from Project PPE (Portfolio Predicate on Exemplar) on EIM. The study employed a developmental-quasi experimental design. The developed lecture-demo video was rated Very Satisfactory in content, instructional and technical quality. Analyses found that students who utilized the created lecture-demo video with learning activity sheets outperformed those who used the learning activity sheets on the posttest. The study concluded that the developed lecture-demo video has a positive learning outcome in learners' competency mastery. Likewise, it is widely accepted and recommended for learning purposes as experts evaluate content, instructional, and technical quality.
