He added that when required reading is included as a type of homework, the 10-minute rule might be increased to 15 minutes. Focusing on the amount of time students spend on homework, however, may miss the point. A significant proportion of the research on homework indicates that the positive effects of homework relate to the amount of homework that the student completes rather than the amount of time spent on homework or the amount of homework actually assigned. Thus, simply assigning homework may not produce the desired effect—in fact, ill-structured homework might even have a negative effect on student achievement. Teachers must carefully plan and assign homework in a way that maximizes the potential for student success (see research-Based Homework guidelines). Parent Involvement Another question regarding homework is the extent to which schools should involve parents.
Solving the homework Problem by Flipping the learning
The cooper synthesis (1989a) reported that for junior high school students, the benefits increased as time increased, up to 1 to 2 hours of homework a night, and then decreased. The cooper, robinson, and Patall (2006) study reported similar findings: 7 to 12 hours of homework per week produced the largest effect size for 12th essays grade students. The researchers suggested that for 12th graders the optimum amount of homework might lie between.5 and.5 hours per night, but they cautioned that no hard-and-fast rules are warranted. Still, researchers have offered various recommendations. For example, good and Brophy (2003) cautioned that teachers must take care not to assign too much homework. They suggested that homework must be realistic in length and difficulty given the students' abilities to work independently. Thus, 5 to 10 minutes per subject might be appropriate for 4th graders, whereas 30 to 60 minutes might be appropriate for college-bound high school students. 394) cooper, robinson, and Patall (2006) also issued a strong warning about too much homework: even for these oldest students, too much homework may diminish its effectiveness or even become counterproductive. (p 53) cooper (2007) suggested that research findings support the common 10-minute rule (p. 92 which essay states that all daily homework assignments combined should take about as long to complete as 10 minutes multiplied by the student's grade level.
In his early meta-analysis, cooper (1989a) reported the following effect sizes (p. 71 Grades 46:.15 (Percentile gain 6) Grades 79:.31 (Percentile gain 12) Grades 1012:.64 (Percentile gain 24) The pattern clearly indicates that homework has smaller effects at lower grade levels. Even so, cooper (1989b) still recommended homework for elementary students because homework for young children should help them develop good study habits, foster positive attitudes toward school, and communicate to students the idea that learning takes work at home as well as at school. 90) The cooper, robinson, and Patall (2006) meta-analysis found the same pattern of stronger relationships at the secondary level but also identified a number of studies at grades 2, 3, and 4 demonstrating positive effects for homework. In The battle over Homework (2007 cooper noted that homework should have different purposes at different grade levels: For students in the earliest grades, it should foster positive attitudes, habits, and character traits; permit appropriate parent involvement; and reinforce learning of simple skills night introduced. For students in upper elementary grades, it should play a more direct role in fostering improved school achievement. In 6th grade and beyond, it should play an important role in improving standardized test scores and grades. Time Spent on Homework One of the more contentious issues in the homework debate is the amount of time students should spend on homework.
Students spend studying core academic subjects compared with students in other countries that typically outperform the United States academically, such as Japan, germany, and France. The study found that students abroad are required to work on demanding subject matter at least twice as long as are. Students (National Education Commission on Time and learning, 1994,. To drop the use of homework, then, a school or district would be obliged to identify a practice that produces a similar effect within the confines of the school day without taking away or diminishing the benefits of other academic activities—no easy accomplishment. A better approach is to ensure that teachers use homework effectively. To enact effective homework policies, however, schools and districts must address the following issues. Grade level Although teachers across the K12 spectrum commonly assign homework, research has produced no clear-cut consensus on the benefits of homework at the early elementary grade levels.
All three of the books criticizing homework provide compelling anecdotes to this effect. Schools should strengthen their policies to ensure that teachers use homework properly. If a district or school discards homework altogether, however, it will be throwing away a powerful instructional tool. Cooper and colleagues' (2006) comparison of homework with no homework indicates that the average student in a class in which appropriate homework was assigned would score 23 percentile points higher on tests of the knowledge addressed in that class than the average student. Perhaps the most important advantage of homework is that it can enhance achievement by extending learning beyond the school day. This characteristic is important because. Students spend much less time studying academic content than students in other countries. A 1994 report examined the amount of time.

84) he also attacked a section on homework in our book classroom Instruction that Works (Marzano, pickering, pollock, 2001). Kohn concluded that research fails to demonstrate homework's effectiveness as an instructional tool and recommended changing the default state from an expectation that homework will be assigned to an expectation that homework will not vas be assigned. According to kohn, teachers should only assign homework when they can justify that the assignments are beneficial (2006a,. 166)—ideally involving students in activities appropriate for the home, such as performing an experiment in the kitchen, cooking, doing crossword puzzles with the family, watching good tv shows, or reading. Finally, kohn urged teachers to involve students in deciding what homework, and how much, they should. Some of Kohn's recommendations have merit. For example, it makes good sense to only assign homework that is beneficial to student learning instead of assigning homework as a matter of policy.
Many of those who conduct research on homework explicitly or implicitly recommend this practice. However, his misunderstanding or misrepresentation of the research sends the inaccurate message that research does not support homework. As Figure 1 indicates, homework has decades of research supporting its effective use. Kohn's allegations that researchers are trying to mislead practitioners and the general public are unfounded and detract from a useful debate on effective practice. 1 The dangers of Ignoring the research Certainly, inappropriate homework may produce little or no benefit—it may even decrease student achievement.
Culture that overvalues work to the detriment of personal and familial well-being. The authors focused particularly on the harm to economically disadvantaged students, who are unintentionally penalized because their environments often make it almost impossible to complete assignments at home. The authors called for people to unite against homework and to lobby for an extended school day instead. A similar call for action came from Bennett and Kalish (2006) in The case Against Homework: How Homework Is Hurting Our Children and What we can do about. These authors criticized both the quantity and quality of homework.
They provided evidence that too much homework harms students' health and family time, and they asserted that teachers are not well trained in how to assign homework. The authors suggested that individuals and parent groups should insist that teachers reduce the amount of homework, design more valuable assignments, and avoid homework altogether over breaks and holidays. In a third book, the homework myth: Why our Kids Get too much of a bad Thing (2006a kohn took direct aim at the research on homework. In this book and in a recent article in Phi delta kappan (2006b he became quite personal in his condemnation of researchers. For example, referring to harris cooper, the lead author of the two leading meta-analyses on homework, kohn noted, a careful reading of cooper's own studies. Reveals further examples of his determination to massage the numbers until they yield something—anything—on which to construct a defense of homework for younger children.

Figure 1 reports only those results from experimental/control comparisons for these two studies. 1 Reported in Fraser, walberg, welch, hattie, 1987. 2 Reported in kavale, 1988. Two meta-analyses by cooper and colleagues (Cooper, 1989a; cooper, robinson, patall, 2006) are the most comprehensive and rigorous. The 1989 meta-analysis reviewed research dating as far back as the 1930s; the 2006 study reviewed research from 1987 to 2003. Commenting on studies that attempted to examine the causal relationship between homework and student achievement by comparing experimental (homework) real and control (no homework) groups, cooper, robinson, and Patall (2006) noted, with only rare exceptions, the relationship between the amount of homework students do and their. Therefore, we think it would not be imprudent, based on the evidence in hand, to conclude that doing homework causes improved academic achievement. 48) The case Against Homework Although the research support for homework is compelling, the case against homework is popular. The End of Homework: How Homework disrupts Families, overburdens Children, and Limits learning by Kralovec and buell (2000 considered by many to be the first high-profile attack on homework, asserted that homework contributes to a corporate-style, competitive.

Homework is typically defined as any tasks assigned to students by school teachers that are meant to be carried out during nonschool hours (Cooper, 1989a,. A number of synthesis studies have been conducted on homework, spanning a broad range of methodologies and levels of specificity (see fig. Some are quite general and mix the results from experimental studies with correlational studies.
Don't be afraid to rearrange things to suit your taste. 3 graphically, the solution is: The only difference between the linear equation " 4 x 6 3 x 5 " and this inequality is thesis the "less than or equal to" sign in place of a plain "equals" sign. The solution method is exactly the same. Note that the solution to a "less than or equal to" inequality is graphed with a square bracket (or else a closed dot) at the endpoint, indicating that the endpoint is included within the solution. 4 graphically, the solution is: The solution method here is to divide both sides by a positive two.

Solving Inequalities: An overview (page 1 of 3 sections: Linear inequalities, quadratic inequalities, other inequalities, solving linear inequalities is very similar to solving linear equations, except for one small but important detail: you flip the inequality sign whenever you multiply or divide the inequality. The easiest way to show this is with some examples: 1). Graphically, the solution is: The only difference between the linear equation " x 3 2 " and this linear inequality is that I have a "less than" sign, instead of an "equals" sign. The solution method is exactly the same: subtract 3 from either side. Note that the solution to a "less than, but not equal to" inequality is graphed with a parentheses (or else an open dot) at the endpoint, indicating that the endpoint is not included within the solution. 2 graphically, the solution is: The only difference between the linear equation " 2 x 0 " and this linear inequality is the "greater than" sign in place of an "equals" sign. Note that " x " in the solution does not "have" to be on the left. However, it is often easier fuller to picture what the solution means with the variable on the left.
