Seminars are one method to enhance, educating and training professionals and students in a specific field. Seminars are now held via technological platforms due to pandemic. It is a recurring question whether web-seminars or webinars are an effective medium for improving knowledge and skills in the same way that seminars have always been. The purpose of this study is to determine whether the teachers, students, and other webinar participants improved their learning after attending. To analyze, an evaluation assessment was done to identify participants' knowledge and skills before and after the webinar. It reveals that the knowledge and skills of the participants before and after the webinar are significantly different. It demonstrates that the percentage of their learning has increased because of attending webinars. Here as result, the study concludes that webinars are an effective medium of teaching and learning, on par with seminars, because they contribute significantly to the improvement of knowledge and skills of all the attendees.
