What is an effective way to learn is a hotly debated issue in education. While some university teachers believe that it is helpful for students to listen to the lecture before class, others think that class time should be devoted to active listening and note-taking. I believe that it is more beneficial to listen to the lecture in advance, for students will have a better idea of which content areas they struggle with, can participate in more engaging activities in class, and have a widely accessible resource at hand.
To start off, if students are able to listen to the recorded lecture before class, they would have more in-depth knowledge of the lecture material. For one thing, a more comprehensive grasp means that students would have a greater understanding of areas they need clarification on, resulting in more useful questions for the teacher. If students go into a lecture without any background knowledge, they would be too busy absorbing new information to know specifically which areas they struggle with. For another, greater familiarity means that students can engage more productively with the content during class. Previewing the material beforehand allows students to form their own perspectives and opinions, making it easier to participate in classroom discussions. Combining these two factors together, recorded lectures are an excellent way to aid both student understanding and class participation.
What’s more, listening to the lecture before class enables class time to be given to activities that actively engage with the lecture content. While lectures provide the students with relevant knowledge, class discussions, along with practice in the form of problem-solving exercises or writing tasks, help to solidify that understanding. When students are freed from the pressures of rigorous note-taking, they are able to redirect their attention to actually learning and practicing the course material. By doing so, students are more likely to stay focused, retain what they have learned, and develop a deeper understanding of the material.
Lastly, recorded lectures serve as a valuable and highly accessible resource for students. For example, some students may be slow writers, so they may struggle to write down all the lecture notes in the given time. Others may have trouble determining the key information to record. Still others may not be native English speakers and find it difficult to keep up with everything the professor is saying. With these barriers removed, recorded lectures can widen accessibility to promote more in-class learning.
In conclusion, listening to recorded lectures before class is a very effective way to learn. Not only are the lectures a vital resource in themselves, students who listen to them in advance can ask relevant questions and become more involved in class activities.
Nowadays how to enhance university education has aroused discussion among both students and teachers. It is suggested by some professors that recording lectures before classes can improve effectiveness since students can be much familiar with the lecture
in advance and teachers therefore can focus on practice on class In my opinion, this practice actually does not have desirable effects for no matter students or teachers.
It is true that a great deal of class time can be saved if lectures are watched previously by students. In university classes, students often gather in a huge hall or classroom which is often in a noisy and smelly environment. This condition may distract students from lectures delivered by professors and thus result in a low academic performance. Therefore, if each student can preview the lecture before it is given by teachers, they can avoid distraction on class and apply themselves to the preview study. Thus, class time is saved because teachers do not need to explain everything in detail but to focus on the difficult onesHowever as far as i am concerned if class proceeds in this way, the whole class would be in chaos and much more energy is needed for teachers to prepare the recording class.
For students, they cannot havean organized lecture if the class is only for discussion and practice. although students can familiarize the lecture in advance, they may have different understandings on the lecture. Without teachers' explanation they may have
confusion and misunderstanding, Which cannot guarantee a satisfying result of self-study. Besides, since students' probloms are not always the same it demands teachers to explain each academic point in class this also means that the whole class is unpredictable and teachers cannot organize the class previously or maybe they would give the same lecture as the recording if most of students cannot understand the lecture depending on themselves Another drawback is that teachers must allocate more time and energy to prepare the recorded lecture, which is a waste of resources. As all know it is time consuming to produce a recorded lecture because it involves many modern techniques. Meanwhile many aged and prestige professors are not that skillful in recording, powerpoint and may feel unconfident about their appearance Thus, if this practice becomes a routine, they have no way but to spend more time and energy on coping with this non-academic issues. In fact, university teachers can use this period of time to improve their academic leveland achieve higher academic achievement.
In conclusion, although previewing the recorded lecture and then discussing and practicing on class seems efficient, I believe we need to stick to the tradition alway of teaching and learning at the moment.
