Various opinions may exist over which style of classes do people prefer, discussions without lectures or lectures without discussions. With respect to this subject, many people are liable to think that lectures should be main things in classes. That being said, from another point of view, sharing opinions in lectures could be more likely to have several advantages in many ways. I also have the same idea on the matter for the following two reasons.
To begin with, Given that the contents students gives in lectures, it tends to have more chances to brainstorm their knowledge about subjects. In this sense, this kind of discussion allows students to attain new information that cannot learn from regular classes and materials. This will be able to help students to have a wide range of background knowledge. To explain this, I will illustrate my compelling experience as an example. When I was a college student, I took an applied physics class. This class mainly consisted of a group discussion and presentations. Although I learned the concept of relative mass in the class, I did not fully understand what the relative mass was at that time. So I put the concept as a topic in my group discussion, and my group members explained the definition of this concept with comparing with the other concepts that is similar to the relative mass. I finally obtained it completely, and I could present the idea of relative mass in front of many students well in the class.
On top of that, this discussion-based lecture generally has better surroundings to study in a greater depth. This atmosphere can make students show their curiosities and lack of knowledge about subjects in good way without being embarrassing. Therefore, the students are easily motivated and enthusiastic to study more and have concrete knowledge taking the others opinions. There was a poll conducted by the Ministry of Education with 500 high school students as respondents. The purpose of the survey was to ascertain the efficiency of two lectures that one was lecture-based and the other was discussion-based. After 2 months taking two different lectures, the students answered questionnaires. An overwhelming 80 percent had responded that lecture that only delivered contents did not impress the students well. However, the discussion-based class makes students put more time to study and get more lesson through the process of sharing other opinions. This corroborates the aforementioned idea that classes having more discussion help students to be motivated well.
In a nutshell, it hardly comes to the convincing conclusion everyone agrees with. Nevertheless, taking the two reasons described above into consideration, it is clear-cut that classes with more discussions have positive impacts on students' academic performances.
