In my opinion, traditional lectures are more fascinating for the students, allow to establish contact and to interact with the audience.The teacher can demonstrate his skills, respond to the students' reactions, change from different types of assignments, keep attention and engagement. It is difficult to replace lively communication and discussion. Nevertheless, the demand of our time to use innovative technologies of teaching and learning. Students want more interactive sessions. Thanks to the internet, everyone can find and study the materials themselves, so the role of lecturer has changed. I think, the best way to gain knowledge is to learn on their own and to participate in face-to-face teaching. So blended teaching is the most appropriate strategy.
Of course, video lectures cannot be underestimated. Recording a video lecture requires a lot of time and special skills, but it gives a certain result. Video lectures improve knowledge. You can watch it back at any moment. Using video depends on the discipline. I think that more effective to create instructional videos, it keeps a lot of time. It is very effective to create videos of conducting experiments or laboratory exercises, for example. I support any modern technology that improves learning outcomes.
