Content Validity and Acceptability of a Developed Video Tutorial for Grade 7 in Science of Banisil National High School

Abstract

INTRODUCTION

Effective integrated science instruction requires a teacher who is fully committed to using innovative teaching methods, real-life tasks, a variety of assessments, and the ability to adapt instruction to best meet the needs of all students. None of these traits is present in isolation; instead, the teacher employs them in concert to create a learning environment that is rigorous, thoughtful, challenging, and innovative. A great K-12 science teacher engages students, uses multiple assessment methods, adjusts instruction like their goals, and makes a connection just like how teachers continually seek ways to connect the integrated science instruction to other subject areas and real-world experiences and have strong content knowledge.

METHODS

The study utilized the descriptive-correlational method in determining the validity and acceptability of the developed video tutorial and the significant difference between the evaluation of experts/teachers and the student-respondents. A quasi-experimental design was also used to find out if the video tutorial is effective in teaching the subject employing t-test for correlated/uncorrelated samples and t-test for independent samples.

RESULTS

As far as the validity of the video tutorial is concerned, the teachers and students registered a grand mean evaluation of 4.09 and 4.00 with an overall grand mean of 4.04, which means that the content validity as a whole is "very much valid". This indicates that the respondents strongly agreed that its different parts as to the Acceptability, Usability, Relevance, and Effectiveness are useful and related to the different topics included in the Science subject. This further indicates that the validity measures done by the assessors determine the students' knowledge, skills, and other attributes. This conforms to the findings of Gayagay's (2014) study on validating a learning package for Grade 7 Science.

DISCUSSIONS

The Video Tutorial's level of acceptability was determined by the teacher and student-respondents evaluating the different aspects as to acceptability, usability, relevance, and Effectiveness. The result of the evaluation is now presented. The teachers and students rated this with grand means of 4.09 and 4.00 respectively and an overall grand mean of 4.04. This indicates that both groups of respondents strongly agreed that the video tutorial met the criteria set and therefore rated as "very much acceptable".
