Abstract/Summary

Education can play a role in promoting the local citrus industry through the contextualization of science instructional activities which utilize some of the processes involved in citrus production. This study aims to develop a teaching model utilizing citrus as instructional material which is based on the pre-service teachers’ Citrus Industry Awareness (CIA) and Citrus Product Patronage (CPP), perception about waste management in teaching and the use of citrus as instructional material. The Bachelor in Elementary Education, Bachelor in Secondary Education, and Bachelor in Technology and Livelihood Education course programs offer science-oriented course subjects which are related and necessary to improve pre-service teachers’ scientific knowledge, attitudes, and skills. Horizontal articulation across the science-oriented subjects involved the preparation of classroom and laboratory activities that use the same primary instructional material and method; hence, the Zero-waste Material Cycling and Industry-oriented Instructional Activities (ZMCIIA). In this framework, citrus fruits of Nueva Vizcaya, Philippines are used as instructional activities for Earth Science, Analytical Chemistry, and Microbiology subjects for BSED. The citrus products and waste materials from these instructional activities were used in General Chemistry and Ecology subjects for BEED and in Industrial Education and Marketing course subjects for BTLED. Quantitative and qualitative analyses of the survey, essays, reflections, ZMCIIA write-up rating and laboratory skills and performance rating of the pre-service teachers revealed that the instructional material cycling of the citrus products and wastes derived from the activities ensures material efficiency and waste utilization. This articulating teaching model lessens the overall amount of waste materials discarded every after the conduct of the instructional activities while promoting awareness and patronage for the local citrus industry in Nueva Vizcaya and enhances the scientific knowledge, attitude and skills of the pre-service teachers.
