Preface

The concept of virtual/online learning is the next paradigm of education. During the hard times of COVID-19, the whole world was locked in their homes with no option to go to school, colleges, or offices. This led to the rise of virtual learning platforms. Virtual learning signifies the use of digital platforms where in the students are taught by the teacher in a virtual class with the help of live audio and video streaming. The classes are conducted in a real-time (synchronous) environment.

Virtual learning is being chosen over instruction in traditional classrooms by most people. There are several reasons for the same, such as flexibility in virtual learning through which full-time workers who cannot attend the classroom may continue to pursue their education and is also a good option for people who enjoy self-learning. Virtual learning has an option for attending scheduled classes or one can learn at his own pace. With the latter option, one can enjoy the benefits of guided lessons along with autonomy with intensity and overall cadence. It also allows one to explore a skill or subject without any commitment to an in-person class. Short introductory courses or long in-depth masterclasses can be found on multiple subjects and skills.

Virtual learning being online is often convenient, flexible and affordable and has the option to either enroll fully online or choose to enroll for online classes as well as in-person classes. As the students do not require to commute for the class and paper waste is less, virtual learning forms an environment-friendly learning option. However, self-discipline is required for virtual learning. The environment can have an impact on the mindset. The classroom environment trains the brain to be in learning mode. Virtual learning helps to avoid distractions and focus on studies. Having a dedicated place or rotation of places for learning may help.

This book focuses on the virtual learning paradigm keeping in mind the technologies like machine learning, virtual reality, augmented reality, mixed reality, blockchain, data analytics, e-learning and education 4.0.
