Some college teachers prefer to ask students to watch or listen to a recorded lecture before class In class they will ask students to do more practices about what they have learned from the lecture Effective or not

It is universally acknowledged that education method is of great importance to humankind as it contributes a large portion to students' intellectual development. The dispute over the specific method that we should used, however, has never come to an end. Recently, some college teachers develop a new teaching style that they ask their students to watch the lecture at home and do more practice in class. While some people prefer this style, I strongly oppose this method from a pedagogy perspective.
To commence with, the concepts studied in university are complicated and abstruse, and it would be difficult for students to grasp them without a teacher explaining to them in person. To be more specific, when watching a video lecture, students are unable to ask their lecturer instantly if they encounter some difficult concepts. They could, of course, ask the lecturer through email. However,they have to wait for the reply before continuing watching the lecture because it is difficult to understand the remaining parts which may be developed on the concept they could not understand. This would lower the study efficiency.
On the top of that, under this teaching method, practicing is overemphasized, and it is putting the cart before the horse. Without a shadow of doubt, the objective of teaching is to let students grasp the concepts. While practicing may help to achieve this, the time teacher spends on elucidating concepts to students is of greater importance. Without understanding the concept beforehand, it would be difficult for students to start practicing. However, in this teaching style, the precious lecture time in which the students and the teacher could interact is used for practicing, and the time of explaining the concepts are depraved. Therefore, this teaching style is not effective.
Despite the manifest reasons above, crictics may still argue that this teaching method is more efficient, because students are allowed to repeatly watch the lecture before they grasp the concepts and they could raise questions when they encounter difficulties during practice time. This kind of opinions, however, has omitted two facts. Firstly, the teacher could record the lesson during a face to face class, which would also allow students to watch the lecture repeatly. Secondly, most of the college courses have tutorial sessions which allow students to practice and raise questions, and it is unnecessary to do that in lecture time again.
Judging from the above evidence, we could safely arrive the conclusion that the teacher should not adopt this teaching style as it lower the teaching efficiency and is unnecessary.
