INTRODUCTION

The COVID-19 pandemic has brought drastic changes to different countries all across the globe. One of the most affected sectors by the current situation is the educational system in the country. The term “new normal” has become one of the most commonly used terms in the pandemic aftermath in most educational situations. This has brought changes necessary to enhance and improve the quality of learning to meet and satisfy the demands of all educational norms and standards. The new normal currently is a modified educational concept, online learning, where students attend classes online instead of being present in a physical classroom. The changes occurring in education have reshaped and molded students and teachers into people with personalities, intellectual ability, and proficiency in different skills that will make them competent enough to acquire continuous advancement of knowledge and learning.

The emergence of technology in education is one of the gradual changes in the education system. In the 21st century, the role of technology in education is shown in different aspects: technology as part of the curriculum and as a tool for delivering instructions and enhancing the students’ learning process (Raja & Nagasubramani, 2018). The integration of technology into the teaching and learning process can contribute to maintaining the high quality of education, especially in the new mode of online learning. There are different approaches and techniques used in studying, in which the only way to adapt to the new educational set-up continually is through utilizing technology. This has led to the discovery and development of various tools and instructional materials for teaching and learning that are often administered during online classes.

In order to improve teachers’ efficiency and students’ performance, instructional materials are necessary instruments for teaching and learning. Instructional materials are developed to help the students be motivated in learning and improve the teachers’ efficacy in teaching. To encourage students to learn, teachers employ a variety of instructional materials like lectures, textbooks, readings multimedia components. These instructional materials are one of the well-defined solutions to address the problem concerning the difficulties encountered by the students, where it provides the learner a more significant opportunity to understand each lesson presented in the material. The success in acquiring knowledge and skills in a subject matter like Earth Science depends on the materials’ applicability, sufficiency, effectiveness, and suitability. One of the effective instructional materials used in teaching Earth Science is the instructional video lesson.

Video lessons are used as a multimedia representation of a particular topic where the viewers can gain relevant and valuable information. Using videos during online learning seems to be an effective tool for engaging students in online classes or even self-paced learning. Internet websites serve as a medium where students and teachers can access videos to modify, design, and develop other versions of video lessons that can be used in learning and teaching a particular subject. The delivery of lessons through videos supports students’ learning process, as it provides opportunities for in-depth learning where concepts and ideas are well presented using images, text, and audio (Greenberg & Zanetis, 2012). In line with this, the section 16 of Article II of the Commission on Higher Education (CHED) Memorandum No. 62, series of 2016, states that it is permissible to legally modify and utilize open educational resources or any educational materials, including textbooks, curricula, lecture, notes, assignments, audio and video that is publicized and introduce to open sources and public domain. The support of the Commission of Higher Education to the utilization of Open Educational Resources, under section 8 of Article I, promotes the universal access to acquiring information and knowledge that teachers and students can manifest.

The use of videos for educational purposes allows both teachers and students to increase their knowledge of the subject matter. Video is one way to effectively deliver a lesson, where these videos make the students motivated and interested in the topic or lesson due to their content, clarity, audio, and design. Teachers utilize these video lessons to extend the opportunity for students to learn more, even at home or during any vacant hours, which is commendable for the teaching and learning process. Through the use of video lessons, teachers can be more resourceful and creative, as they have the opportunity to develop their video lessons. For students, the use of video lessons will help them be more engaged in studying a particular subject, resulting in higher performance during an online class. Also, it will increase their knowledge of the proper utilization of instructional materials.

Video lessons are an effective tool for students’ learning and acquisition of knowledge that students can use in various ways. It allows the students to pause and repeat watching the material to ensure that they fully comprehend the Earth Science lessons. As a result, a study focusing on the development of an instructional video is deemed essential. Through the data and outcomes, it wanted to demonstrate the importance of instructional video and their influence on education. As a result, it is expected that this research may serve as a strong foundation for developing and enhancing instructional materials like instructional video that will be developed relatively soon by students and teachers to overcome incompetence in subject matter learning.

The COVID-19 pandemic significantly impacted the educational system, causing it to be changed into an online learning system. Students and faculty members must undergo various adjustments as they face numerous problems during the online learning setup. Some instructional materials, such as e-modules, hand-outs, and e-books, may not be sufficient to meet students’ needs when it comes to studying at their own pace; therefore, the development of other instructional materials, such as instructional videos, was considered as a well-defined solution to this pressing problem. Instructional videos are an effective tool during the COVID-19 pandemic’s online learning system. It supports student learning by assisting students in becoming more engaged in their studies. Students and faculty members benefit from the instructional video in their teaching process since it allows them to use it conveniently and flexibly. The contents and designs let them further understand the lessons that will be conveyed. Additionally, students will improve their understanding and performance in lessons, notably in Earth Science, with the support of instructional videos.

Description of final the course-based customized instructional video in Earth Science

The developed course-based customized instructional video contains various parts, such as the title of each chapter; the learning objectives that deal with what should be achieved and obtained in each discussion; the introduction has seen at the beginning of the instructional video to introduce the topic; the discussion that was adapted from various sources; the assessment to check the viewers’ understanding of the discussion; and the references for the discussion. The topics in each instructional video were based on the course syllabus of the Earth Science subject.

Along with that, the developed course-based customized instructional video contains information and essential concepts about Earth Science. It supports and aids the faculty members and students in teaching and learning. It is applicable in teaching and learning considering the situation of our educational system today. The developed course-based customized instructional video comprised the appropriate design for the faculty members to properly present the information and engage and motivate the students. It also utilized audio and video quality suitable for presenting the information through video layout, sounds, graphics, illustrations, and voice-over.

CONCLUSION

Based on the findings of the study, the researchers with this concluded that:

  1. The faculty members and students perceived that utilizing a developed course-based customized video lesson is vital in performing their role in the teaching and learning process. This provides various options for an easy and beneficial way of acquiring information.
  2. The respondents’ evaluation of the developed course-based instructional video in Earth Science in terms of the contents, usefulness, relevance, video lesson design, and audio and video quality were acceptable and favorable based on the gathered results. The respondents also provided suggestions that needed to be considered in improving the instructional video.
  3. The respondents assessed and agreed to all the impacts of the instructional video lesson in Earth Science as these materials contributed to teaching and acquiring learning within the course.
  4. There is a correlation between the evaluation of course-based customized instructional video and the impact of the instructional video lesson on learning Earth science. It shows in the study that there is a high positive correlation between the two variables.
  5. The final course-based customized instructional video in Earth Science was described as having different parts that should be followed when developing an instructional video for effective instructional material.

RECOMMENDATIONS

Based on the findings and conclusions made from the study, the accompanying suggestions are thusly proposed by the researchers:

  1. The university may consider using instructional video in the teaching and learning process within a course among the BatStateU-ARASOF Nasugbu students, especially the science students.
  2. The developed course-based customized instructional video should be subjected to revision and editing process before being used in teaching and learning of Earth Science.
  3. Future researchers are allowed to enhance the developed course-based customized instructional video in terms of content, usefulness, relevance, video lesson design, and audio and video quality in order for the faculty members and students to view the instructional materials as effective and efficient. They may also use this study as one of their related literature and references to construct their study.
