The world of education has undergone major changes within the last year that have pushed online instruction to the forefront of learning. Thanks to the COVID-19 pandemic, online learning has become paramount to the continued and uninterrupted teaching of students and has forced students and teachers alike to adjust to an online learning environment. Though some have already returned to the traditional classroom, or plan to very soon, others have begun to appreciate the value of online education - initiatives that had previously been discussed but never acted upon as they have been in the past year. With plenty of positive and negative aspects, online learning is a complex issue with numerous factors to consider. It is an issue that must be studied and examined in order to improve in the future.
