how does homework help you

Is Homework Actually Useful?

Homework has been a longstanding tradition in education, often eliciting mixed feelings from students and parents alike. While some argue that homework can be burdensome and counterproductive, numerous studies in neuroscience and educational research suggest that it plays a crucial role in reinforcing classroom learning, fostering essential skills, and preparing students for future success. Understanding the usefulness of homework can make it much easier for us to do it, as individuals will know they aren't wasting their time.

Enhancing Memory

Neuroscientists have found that spaced repetition, a technique often employed through homework assignments, can significantly improve memory retention. According to a study conducted by Pashler et al. (2007), spacing out study sessions over time strengthens memory recall. When students revisit and review material over time, it strengthens the connections in their brains associated with that knowledge. When a subject is learned in school, there is a period of time for the material to stick into your brain, and recalling that information while doing homework makes that connection stronger. It also simultaneously serves as a consolidating tool, where information is transferred from your short term memory to your long term memory in a process known as memory consolidation. In a study done by Ellenbogen et al. (2007), sleep was found to be vital in this process. Doing your homework before bed can enhance the memory consolidation during sleep and improve your learning.

Neuroplasticity

The brain’s ability to change and adapt, known as neuroplasticity, is essential for learning. It allows our minds to grasp onto and apply abstract concepts. Neuroplasticity is most common amongst young children, which allows them to learn so much information so quickly. However, homework provides opportunities for students to engage their brains in different ways, fostering this adaptability. A study by Draganski et al. (2004) found that learning-induced structural changes in the brain are closely related to the amount of time spent practicing a skill, emphasizing the importance of regular homework practice.

Problem-Solving Skills

Homework assignments often require students to apply what they’ve learned to solve new problems. This challenges their brains to think critically and develop problem-solving skills, which are valuable in various aspects of life. According to a study by Trumbull and Lash (2013), problem-based homework assignments can significantly improve students’ critical thinking abilities, as students cannot simply ask for help. This allows them to stick with problems for much longer than they normally would, allowing their brains room to grow.

Time Management

Completing homework tasks within deadlines encourages students to manage their time effectively, a skill that is vital not only in academics but also in future careers. Research by Hafen et al. (2019) suggests that developing time management skills through homework can lead to better academic outcomes and reduced stress levels among students, which will help, not only school related things, but beyond.

Attention and Focus

Doing homework helps improve attention and focus. A study by Anderson and Dill (2000) found that engaging in tasks that require sustained attention, such as homework, can enhance the brain’s ability to focus on specific tasks. This is particularly important in our digital age, where distractions are abundant. Homework trains the brain to concentrate on specific tasks. This will help individuals learn in school as they have an easier time giving their undivided attention to a single task.

Self-Discipline

Neuroscience studies have shown that self-discipline, a trait cultivated through homework, is a better predictor of academic success than IQ. Homework strengthens the brain’s executive function, aiding in planning, organization, and impulse control. Research by Duckworth and Seligman (2005) highlights the significance of self-discipline in achieving long-term goals, including academic success. By continually doing homework, you are training yourself, and by extension, your brain to have a strong sense of discipline.

Metacognition

Homework often requires students to reflect on their own learning processes. This metacognition, or thinking about thinking, helps students become more aware of their strengths and weaknesses, leading to more effective learning strategies. A study by Schraw et al. (2006) underscores the role of metacognition in academic achievement, showing that students who engage in metacognitive practices perform better in their studies.

Personalized Learning

Neuroscience research indicates that personalized learning experiences can have a more profound impact on long-term memory and comprehension. A study by Pellegrino et al. (2001) highlights the importance of adapting educational strategies to individual learning styles, a principle that can be applied to homework assignments. This is especially important for students dealing with subjects on concepts they struggle with, as they are able to practice it more. In neuroscientific terms, practice leads to myelination, the process of building up the protective sheath around neurons that makes them function more efficiently. Homework provides ample practice, helping students master skills and knowledge. A study by Jenkins et al. (2010) suggests that repeated practice of skills, as often seen in homework assignments, leads to improved neural connectivity associated with those skills.

Preparation for Future Learning

Homework not only reinforces current lessons but also prepares students for future learning. It encourages a growth mindset, where challenges are seen as opportunities for growth, a mindset that is beneficial throughout life. Research by Dweck (2006) highlights the significance of a growth mindset in achieving academic success and lifelong learning.

While the debate over the quantity and nature of homework continues, neuroscience studies consistently highlight the cognitive and behavioral benefits of homework when appropriately designed and implemented. Homework is not merely a mundane task; it is a powerful tool for shaping young minds, enhancing their cognitive abilities, and preparing them for a lifetime of learning and success. The evidence from these studies strongly supports the continued use of homework as a valuable educational practice.

Educators should be thrilled by these numbers. Pleasing a majority of parents regarding homework and having equal numbers of dissenters shouting "too much!" and "too little!" is about as good as they can hope for.

But opinions cannot tell us whether homework works; only research can, which is why my colleagues and I have conducted a combined analysis of dozens of homework studies to examine whether homework is beneficial and what amount of homework is appropriate for our children.

The homework question is best answered by comparing students who are assigned homework with students assigned no homework but who are similar in other ways. The results of such studies suggest that homework can improve students' scores on the class tests that come at the end of a topic. Students assigned homework in 2nd grade did better on math, 3rd and 4th graders did better on English skills and vocabulary, 5th graders on social studies, 9th through 12th graders on American history, and 12th graders on Shakespeare.

Less authoritative are 12 studies that link the amount of homework to achievement, but control for lots of other factors that might influence this connection. These types of studies, often based on national samples of students, also find a positive link between time on homework and achievement.

Yet other studies simply correlate homework and achievement with no attempt to control for student differences. In 35 such studies, about 77 percent find the link between homework and achievement is positive. Most interesting, though, is these results suggest little or no relationship between homework and achievement for elementary school students.

Why might that be? Younger children have less developed study habits and are less able to tune out distractions at home. Studies also suggest that young students who are struggling in school take more time to complete homework assignments simply because these assignments are more difficult for them.

These recommendations are consistent with the conclusions reached by our analysis. Practice assignments do improve scores on class tests at all grade levels. A little amount of homework may help elementary school students build study habits. Homework for junior high students appears to reach the point of diminishing returns after about 90 minutes a night. For high school students, the positive line continues to climb until between 90 minutes and 2½ hours of homework a night, after which returns diminish.

Beyond achievement, proponents of homework argue that it can have many other beneficial effects. They claim it can help students develop good study habits so they are ready to grow as their cognitive capacities mature. It can help students recognize that learning can occur at home as well as at school. Homework can foster independent learning and responsible character traits. And it can give parents an opportunity to see what's going on at school and let them express positive attitudes toward achievement.

Opponents of homework counter that it can also have negative effects. They argue it can lead to boredom with schoolwork, since all activities remain interesting only for so long. Homework can deny students access to leisure activities that also teach important life skills. Parents can get too involved in homework -- pressuring their child and confusing him by using different instructional techniques than the teacher.

My feeling is that homework policies should prescribe amounts of homework consistent with the research evidence, but which also give individual schools and teachers some flexibility to take into account the unique needs and circumstances of their students and families. In general, teachers should avoid either extreme.
