Development and Validation of Flipbook in Earth and Life Science

Abstract

This paper focused on the development and validation of a Flipbook in Earth and Life Science, a Senior High School subject in the Philippine K-12 curriculum. Purposive sampling technique was employed in determining the validators of the essential learning competencies and the developed Flipbook. Using Lawshe’s content validity formula, 28 out of 67 learning competencies in the subject were identified as essential based on the evaluation of ten subject matter experts who identified the content to be included. The developed Flipbook in Earth and Life Science consisted of twelve lessons and each lesson consisted of the following: a) overview of the lesson, b) learning objectives, c) pre-assessment, d) discussions, e) post-assessment, and d) references. A validation tool was used by eight (8) experts to evaluate the a) content, b) pedagogy, c) format, and d) technological factors of the developed Flipbook. Moreover, descriptive statistics was also used in analyzing the ratings of the experts. The Flipbook undergone revisions until all criteria has been satisfied. Results revealed that the Flipbook in Earth and Life Science is valid and acceptable in terms of content, pedagogy, format, and technological. The experts provided positive overview of the module. Therefore, the Flipbook in Earth and Life Science is generally commendable and can be used as a learning material or reference in teaching Earth and Life Science in Senior High School.
