English article about you have heard about a school allows students to decide which subjects are tought​
Inessa [10]

Answer:

In today’s modern world, education has come a really long way. Nowadays, schools are giving their pupils the chance to decide which subjects they are taught, even in early grades such as grade 6. This has sparked many debates on whether giving the students this opportunity is going to be beneficial or not. I believe that this can be advantageous for the students.

Firstly, giving students the opportunity to decide which subjects they are taught can greatly boost the students’ morale. Moreover, as they would be only studying what they want, they would be less likely to drop subjects. Also, the increased motivation can result in the students performing better in their studies. In addition, some students may choose less subjects if they are given this opportunity and this would allow them to spend more time and focus on the subjects of their choice.

Giving students the opportunity to choose which subjects they are taught can make the students feel more responsible. This is because they would feel that their performance is in their hands. This is likely going to make the students think more about their career. Also, they would be more compelled to do better in the subjects that they have chosen because these subjects would be somewhat or even directly related to their dream careers. Additionally, it would also make the students feel more free and independent.

In conclusion, due to its various benefits, I think that schools should be giving its students the opportunity to decide which subjects they are taught. However, there must also be some mandatory subjects like Mathematics and language that are essential for all professions.
