**1. Introduction**

Distance learning is not necessarily a new paradigm; it has existed for many generations, and predates the birth of television and video. It has evolved from using the postal service to the point where online learning has become the norm that can happen anywhere, anytime, from anyone through the internet [1]. In recent years, online education has experienced a remarkable transformation primarily due to the advent of revolutionary videos. In this book chapter, we delve into the exciting realm of online learning and how cutting-edge videos are transforming it. Our focus lies on exploring various aspects of online education, specifically in the domains of declarative learning, asynchronous and synchronous learning, interactive videos, procedural learning in healthcare education, and gamified learning. Throughout the chapter, we unravel the intricate role of videos in learning, illuminating how they not only revolutionized but also fundamentally reshaped online education.

The chapter begins by examining the concept of declarative learning, which involves the acquisition and retention of factual knowledge. The authors explore the role of videos in supporting declarative learning, emphasizing how they can draw in students using both visual and auditory cues. Videos have revolutionized the way learners acquire and retain declarative knowledge by presenting information in an interactive and engaging fashion, leading to more effective and efficient learning.

Next, we explore the domain of synchronous and asynchronous learning within online education. Online learning without videos is like the silent film era of movies. Video recordings and video conferences have become indispensable elements

of learning. Undoubtedly, videos have significantly advanced online learning to an unprecedented level. This chapter highlights how videos have significantly improved the adaptability and practicality of asynchronous learning. Learners can interact with instructional information whenever and wherever they choose by watching pre-recorded videos at their own pace and convenience. We also explore how videos affect synchronous learning, which enables real-time communication and teamwork between students and teachers. Videos have completely changed how students engage in synchronous and asynchronous learning. The revolutionized technology of videos has brought world-class courses to our fingertips, increasing maximum accessibility and flexibility [2].

Interactive movies have become a potent tool in online education for encouraging student involvement and active learning. This chapter examines several interactive components used in videos, including simulations, branching scenarios, and quizzes. These components encourage students to take an active role, make choices, and hone their critical thinking and problem-solving abilities. We explore how the distribution of instructional content can be revolutionized using interactive films, resulting in more engaging content. Video game, a mature industry and persuasive influential factor in certain Western cultures, has also found its place in education from K-12 all the way up to professional schools [3]. Indeed, videos have become influential tools in online learning with the advancement of technology.

A significant focus of the chapter revolves around the impact of videos on procedural learning, especially in healthcare education. We delve into how step-by-step instruction-based procedures and techniques can now be taught and learned with videos. Healthcare professionals can learn and analyze these procedure learning via video demonstrations, ensuring precise skill acquisition and performance. We discuss how videos can revolutionize healthcare education by improving procedural learning results and, eventually, better patient care.

Finally, we investigate how gamified learning might be included within the online learning environment. We explore the idea of "gamification," which adds gaming elements to the educational process to boost student enjoyment and motivation. Through captivating scenarios, videos have been used to deliver gamified learning experiences, amplifying learners' motivation, involvement, and retention of the material. We demonstrate the revolutionary potential of gamified films, which transform online learning by enriching its interactivity, stimulation, and efficacy.

This chapter concludes with a comprehensive examination of the revolutionary influence of videos on various aspects of online education. We hope to shed light on how videos have reshaped the landscape of online education, focusing on declarative learning, asynchronous and synchronous learning, interactive videos, procedural learning in healthcare education, and gamified learning. With this chapter, we aim to further advance the ongoing evolution of online learning practices by encouraging more research and discussion on the integration of videos in education.
