Independent Writing Task
Nowadays, many students are not interested in their classes.
Which of the following ways do you think would be the most effective way that a teacher can use to make students get interested in classes?
1、Using technology in the classroom more often；
2、Ask students to have group talk more often；
3、Explain to the students what they learned is related to the world outside classroom.
至于本题第三个选项，教育与现实世界关系，也并非旧题，2018年9月2日真题：The best way for a teacher to help students interested in a subject is to explain that subject will help them outside school. A/D 与本题第三个选项十分相似，同时重复2014年12月6日真题。
所以，虽然题目是新题，但其实不过是常考题目的一次大融合，新瓶装旧酒罢了。只是同学们在审题时要注意，题目中的核心词，get interested in，最终目的应在让学生们感兴趣。可以思考每个选项与感兴趣之间的关系。
As the old saying goes, interest is the best teacher. Students motivated by intrinsic interest are more likely to achieve academic success, as well as make good preparation for their future development. In order to trigger students’ interest, teachers are doing their utmost. Some choose to take advantage of technology, while other prefer to connect what students learn with the real-world. However, from my perspective, group activities would be much preferable and more practical.
To begin with, group work can easily get students involved in discussions, which can spark their thinking. Compared with interacting with teachers directly, such as answering questions or discussing a task, apparently, participating in group work and communicating with other classmates would be more fascinating. Being curious about what others are thinking and being eager to express their own ideas, students would unconsciously follow suit and become increasingly enthusiasm. Besides, being aware that they can make a contribution in finishing a task together with group members or competing with other groups can help enhance their confidence, encouraging them to participate more.
Making use of technology in class indeed has its merits. For example, some documentaries and video games are quite informative and educational. While imparting the knowledge of Europe’s history during the Renaissance period, such visualized information can make the whole process of learning more interesting. However, we should not neglect the fact that a significant proportion of students are not self-disciplined and can easily get distracted. In other words, the result can not be guaranteed. For instance, they may care too much about the winning or losing of the games, ignoring the what they should learn from them. They may also use electronic products to chat with others or surfing the internet in class.
Explaining the connection between what students learn with the real-world seems to be plausible at first glance. When students have a knowledge of that what they learn can make sense in the future such as landing a well-paid job in the future or even changing the world, they would definitely be more passionate. But the truth is that once students realize that the real-world is actually far away from them, and that it takes a while to apply what they learn, they would lose their enthusiasm in no time, because the interest they have is just related to the achievement in the future, rather than study itself. Extrinsic motivation can not drive people forward for long.
From what has been mentioned above, we can safely draw a conclusion that letting student get engaged in group activities should be the best choice for teachers if they want to stimulate students’ interest in classes since students would be more likely to exchange ideas with others and take the initiative in group work.
