A Look at the Evidence
There is a scene in Walt Disney's animated film The Sorcerer's Apprentice where the
young Mickey Mouse is told by Merlin to fill a cistern with water. After carrying a few
buckets, Mickey decides to use his newly learned magic powers to ease the job by turning a
broom into a water carrier. With a single zap, the trick is done. And while the broom
carries water, Mickey naps.
Unfortunately, when Mickey awakes he finds that, though, the cistern is full the broom
continues to carry water. He also discovers that he does not have the magic to stop the
broom so despite his efforts the water keeps coming. In desperation, Mickey strikes the
broom with an axe but each of the splinters turns into a broom and begins carrying water
also. The frantic Mickey watches helplessly in terror as the unstoppable brooms flood the
castle. Suddenly, an angry Merlin appears and clears the mess with a wave of his hand. As
a teacher he has seen "homework" take a nasty turn!
In recent discussions with parents and students I have heard a variety of opinions
expressed about homework. What has impressed me most is that many of the opinions people
hold about homework are based more on impressions than on the relatively well developed
body of knowledge and research about homework.
Below, this literature is summarized in order to provide a review of the current
thinking about homework focused around some questions I often hear.
First, several generalizations can be made about homework:
- Parents expect teachers to assign homework and believe it is a mark of good schooling.
- Students do not like to do homework, often believe it intrudes on their time and is not
- The value of homework is genuinely unclear and the research on the effects of homework
is relatively poor.
- For all parties involved in schooling, homework has been controversial, is so now and
will continue to be so in the future.
Q: What do we know about the effects of homework on students' achievement?
The research indicates two main conclusions. First, there is a long and substantial
tradition of assigning homework. Though the belief in homework waxes and wanes, it has
consistently been used by teachers and expected by parents. Homework tends to become more
important and increase in volume during periods of "reform" such as following
the launch of Sputnik in the late 50's and the current "A Nation at Risk"
inspired basic education revival. It may be that homework is tangible evidence for us that
something is being done to improve education.
Second, the research on homework provides little experimental support for its value in
increasing achievement. Nearly every experimental study which supports homework is
balanced by a study which shows no effect. However, studies of homework appear to show no
negative effects on achievement.
On the other hand, correlational studies tend to indicate that homework is a positive
correlate with achievement. These large scale analyses of data reveal a positive but
modest relationship between homework and achievement. A problem with these studies is that
many other variables are also associated with higher achievement.
One reasonable conclusion may be that better schools with better students assign more
homework. This, of course, does not imply that assigning more homework will result in
either a school's or its students' achievement improving.
Q: Why is the homework "picture" so confusing?
One reason is because the issues are complex. From personal experience most of us know
that homework can be both good and bad. It is very difficult to isolate effects when so
much variation in quality exists. There are some generally accepted types, purposes and
guidelines for homework which may be helpful in understanding the homework confusion.
Researchers Lee and Pruitt (1979) identified three types of homework:
- Practice: This is the most familiar and frequent type of homework which isusually
assigned to reinforce lessons taught during school. Typical practice assignments are to
complete 20 math problems, memorize grammar rules and balance chemical formulas. In other
words, this is mostly drill which is usually repetitive. Some research indicates that
these types of assignments are of questionable value.
A frequent problem with practice
homework is boredom for those who can do the practice. For those who cannot, confusion and
frustration is a difficulty. These latter students may actually be learning to do the work
incorrectly particularly when homework is not corrected.
- Preparation: With this type of homework students are assigned to read over
material to be presented in the future in order to gain sufficient information to more
fully learn. There is little indication that such homework will prepare students without
good directions on what, why and how they should read. Thus, preparation assignments
should be oriented to a specific purpose.
- Extension: These homework assignments go beyond classroom presentations. Examples
include individual or group projects, science fairs and "background" reading.
Often these assignments are long term and production (vs. reproduction) oriented.
homework tends to be more individually and choice focused, also. Building a miniature
Roman catapult, a model of a nuclear reactor or cooking a typical Spanish festival meal
can be a good learning experience and fun, as well. Of course,it can also be time
consuming, distracting and expensive.
Q: Why do teachers assign homework?
According to researchers England and Flatley (1985) there are five reasons. These are
- Teaches self discipline.
- Eases times constraints on the curriculum.
- Teaches independence and responsibility.
- Supplements and reinforces school learning.
- Creates a bond between home and school.
It may be sufficient to say only that there are no data which support a relation
between homework and these purposes. Nonetheless, a survey of teachers conducted in 1966
found that 89 of 90 teachers favored homework; another survey in 1989 found that teachers
did not strongly believe homework was beneficial.
Q: What are the characteristics of "good" homework?
Although there is much equivocation about the value and purposes of homework, there is
considerable agreement about what constitutes good homework.
- First, the purpose must be clear to teachers, to students and to parents. It appears
that parents can be most helpful when they and their children understand what is wanted,
the teacher's expectations, how much homework will be assigned and how child and parent
can work together with the teacher. As a teacher, it is wise to identify these policies at
the beginning of the year so all will know what to expect.
- Second, homework should be corrected and returned. It should count, not just be counted.
Teachers can enlist parents to make homework count by ensuring it is correct and
encouraging them to praise and support their children for completing homework.
- Third, homework should gradually increase through the school years. Primary children
should not have homework but beginning in the fourth to fifth grade homework begins and
increases in amount assigned through high school. There is little agreement about how much
should be assigned.
However, homework that is assigned should be coordinated between
teachers. Children at all levels of schooling are more involved in outside activities
(i.e. sports, civic, social, cultural). If six teachers assign 30-40 minutes of homework,
the result is very problematic for students and parents. This can be a very real problem
as indicated in one study which found that teachers consistently underestimate how long
students will spend on the homework they assign. So, it is a good idea for teachers and
parents to discuss homework policies to ensure a proper balance.
- Fourth, the value of homework varies. Sometimes assigned homework will not be what every
child needs to do. If this happens frequently, propose some alternatives to what is
routinely assigned and to communicate better the purpose of the homework.
- Fifth, regardless of public opinion, recognize that homework, while it can be a valuable
strategy, is not absolutely essential as a daily ingredient of quality education. Most
students will not do homework sometimes. Promote but do not expect total compliance.
Q: What can parents do about homework?
The following suggestions may help parents encourage their children to do the homework
- Set a time and place for study/intellectual development -- make this a priority time
which supersedes everything else. Include study other than assigned homework and reading
- Make school associations positive; include occasional special rewards and always make
study very positive.
- Help by doing what you can whenever you can and avoid frustration. Stay calm and
positive even through tears and rejection.
- Help students plan how to attack their assignments and to use their time well.
- Learn with your children and show interest in their learning; discuss and develop ideas
and review and correct homework.
- Test your children on a regular schedule; do this rigorously and thoroughly It is better
for parents and their children to find out what they do not know before a test.
- Develop an attitude of positive acceptance by relating school success to effort, by
being consistent and by being supportive.
- Set a purpose for homework; discuss this with your children (Why are you doing this?
What can you learn from it?).
Clearly the best approach to make homework a valuable and effective component of
classroom instruction is to make sure students and parents understand the purposes of
homework. This understanding should provide parents with the knowledge and interest to
support you and help their children. In this way homework can become a positive link
between the school and the home.
