Development and Validation of a Community-Based Learning Resource Package in Inorganic Chemistry

Abstract

The chief aim of this research work was to develop and validate a learning resource package in inorganic chemistry that is community-based. The study underwent four stages of material validation, namely: preparation, development, validation and try-out. The study employed the descriptive method of research to describe and evaluate the developed learning resource package through a questionnaire checklist. Twelve chemistry experts determined the validity of the said package as to content. One hundred two chemistry students of Mountain Province State Polytechnic College determined the learning resource package’s reliability as to parts specifically on objectives, content, assessment and its instructional characteristics. The resource package was further tried out on two inorganic chemistry classes employing the quasi-experimental method. Preliminary tests and post-tests were administered to the two classes to determine their performance in inorganic chemistry in terms of knowledge acquisition. Responses were tallied, tabulated and treated with appropriate statistical treatment. The study found out that the developed learning resource package was very much valid as to content and very much reliable as to parts and instructional characteristics. Further, students exposed to the developed learning resource package performed better than the students taught without the use of it. Inorganic chemistry lessons can thus be made more culturally-relevant and meaningful to the students through the integration of community-based resources in the form of local products, everyday activities, agricultural practices, natural resources and local industries. This study therefore suggests that the developed learning resource package be adopted for use in the teaching and learning of inorganic chemistry.
