{"abstract":"This study which utilized the research and development design aimed to develop instructional module in enhancing the study and thinking skills of learners and to validate their functionality, relevance, and acceptability. It was conducted in December, 2019 in the Schools Division of Iloilo. The respondents of this study are the 177 senior high school and hybrid English teachers, 30 teacher-validators and 5 experts. The data were gathered using the researcher-made needs analysis survey, and the evaluation tools for functionality and relevance and an adopted instrument for the acceptability. The development of learning modules underwent four phases: (1) document and needs analysis; (2) the development of modules; (3) the evaluation by teacher- validators and expert-evaluators; and (4) finalization and reproduction of modules in their final form. Results show that the teacher-validators perceive the instructional module as highly functional and highly relevant while the experts evaluated the instruments as excellent in all areas of the modules such as the objectives, instruction, learning activities, physical aspects and evaluation measures.","abstract_source":"original","authors":["Nestor Paul Pingil"],"date":"2022-08-19","doi":"10.5281/zenodo.7011370","id":517,"issue":9,"journal":{"issn":"2822-4353","name":"Psychology and Education: A Multidisciplinary Journal"},"pdf_sha256":"4a9996d4577839733412a2b5d3e26a199e39075c666f70fe45efa98802b8fea8","schema":"scimatic-article/1","title":"Development and Validation of Instructional Modules in Enhancing the Study and Thinking Skills of Learners","volume":3}
