according to some student,what is the true purpose homework

What do you think is the whole point of going to school?

To receive education ofcourse. Good grades come in handy in the future.

Puropose of homework--good grades, appreciation from teacher, effort mark, etc.

By the Way this doesn't look like math to me.

Most information is not retained unless you go over and over it. The time in school is not enough to absorb the information. These articles might give some insight to studying.

The true purpose of homework can vary depending on who you ask, but generally speaking, homework serves several purposes:

1. Practice: Homework provides an opportunity for students to practice what they have learned in class. It helps reinforce the concepts and skills being taught and allows students to apply their knowledge independently.

2. Review and Consolidation: Homework encourages students to review and consolidate their learning. It helps to reinforce key concepts and helps students remember what they have learned over time.

3. Preparation: Homework prepares students for upcoming lessons or activities. It can serve as a way to introduce new material or concepts before they are taught in class, enabling students to be better prepared and participate actively during class discussions.

4. Time Management and Responsibility: Homework teaches students important life skills such as time management, organization, and responsibility. It requires students to manage their time effectively, prioritize tasks, and meet deadlines, which are invaluable skills for academic success and later in life.

5. Independent Learning: Homework fosters independent learning and self-discipline. It encourages students to take initiative, work on their own, and develop problem-solving skills, which are crucial for lifelong learning.

It's important to note that opinions about homework can vary among students. While some students appreciate the benefits it offers, others may find it overwhelming or believe that it doesn't effectively enhance their learning. Ultimately, the purpose and effectiveness of homework may depend on the specific context, the teacher's approach, and the individual student's learning style and preferences.
