Brian Sztabnik, a veteran middle and high school English teacher, suggests that teachers take a step back and ask themselves these five questions :. When students spend too much time on homework-more than two hours each night-it takes up valuable time to rest and spend time with family and friends.

Teachers should also keep in mind that not all students have equal opportunities to finish their homework at home, so incomplete homework may not be a true reflection of their learning-it may be more a result of issues they face outside of school. They may be hindered by issues such as lack of a quiet space at home, resources such as a computer or broadband connectivity, or parental support OECD, In such cases, giving low homework scores may be unfair. Since the quantities of time discussed here are totals, teachers in middle and high school should be aware of how much homework other teachers are assigning.

Marzano homework and practice powerpoint 9. Multimedia Tools Interactives and Simulations Primary Sources Taking the opposite view, researchers Robert Marzano and Debra Pickering have voiced their support for purposeful homework that reinforces learning outside of school hours but still leaves time for other activities. Inprominent homework scholar Harris Cooper published a meta-analysis of more than studies on homework in a survey that found a correlation between homework and performance on standardized tests, but only for certain grade levels.

However, there was no evidence of the same correlation for younger students. As a result, homework can shape family dynamics and weeknight schedules. If a child receives too much homework, or only busywork, it can cause stress within families and resentment among parents. It is no surprise that the debate over homework often spills onto the pages of newspapers and magazines, with calls to abolish homework regularly appearing in the headlines.

Inthe superintendent of Marion County Public Schools in Florida joined districts in Massachusetts and Vermont in announcing a homework ban. To justify his decision, he used research from the University of Tennessee that showed that homework does not improve student achievement. The survey sought to better understand the nature of homework as well as whether the homework assigned was aligned to rigorous academic standards.

Based on the best knowledge of the authors, the CAP survey and this report represent the first-ever national study of homework rigor and alignment to the Common Core State Standards-rigorous academic standards developed in a state-led process inwhich are currently in place in 41 states and Washington, D.

The CAP study adds to existing research on homework by marzano homework and practice powerpoint on the quality of assignments rather than the overall science research papers of homework of any type.

There are previous studies that considered parental involvement and the potential stress on parents related to homework, but the authors believe that this report represents the first national study of parent attitudes toward homework.

In all, parents responded to the survey, with CAP analyzing homework assignments. Admittedly, the methodological approach has limitations. However, research has shown that MTurk yields high-quality, nationally representative results, with data that are at least as reliable as those obtained via traditional methods. In addition, the homework sample is not from a single classroom or school over the course of a year; rather, it is a snapshot of homework across many classrooms during marzano homework effect size span of a few weeks marzano homework effect size May The assumption is that looking at assignments from many classrooms over a short period of time helps to construct a composite picture of mathematics and language arts homework.

Moreover, the design of the CAP study has clear advantages. Many of the previous existing studies evaluated homework in a single district, whereas the CAP study draws from a national sample, and despite its limitations, the authors believe that the findings are robust and contribute significantly to the existing research on homework. Based on these key findings, CAP recommends that states, districts, and schools improve the quality of homework and increase opportunities for students to practice rigorous grade-level content at home.

Specifically, the authors-drawing from this survey and other existing research on homework-recommend the following actions to improve the role of homework in education:. Homework should be engaging and aligned to Common Core standards, which allow students to develop deeper-level learning skills-such as analysis or conceptualization-that help them increase retention of content.

All homework is not created equal. The CAP study sought to evaluate homework quality-specifically, if homework is aligned to rigorous content standards. The authors believe that access to grade-level content at home will increase the positive impact of adopting more rigorous content standards, and they sought to examine if homework is aligned to the topics and skill level in the content standards.

According to Harris Cooper, homework is a valuable tool, but there is such a thing as too much. InCooper and his colleagues argued that spending a lot of time on homework can be counterproductive. He believes that research supports the minute rule-that students should be able to complete their homework in no more than 10 minutes multiplied by their grade.

For example, this would amount to 20 minutes for a second-grade student, 50 minutes for a fifth-grade student, and so on.

In language arts, the standards moved students away from narrative-based assignments, instead concentrating on using evidence to build arguments and reading more nonfiction. The Common Core is not silent in the cognitive demand needed to demonstrate mastery for each standard. There are numerous frameworks to describe levels of cognitive skills.

What works best - The Economics Network

The original levels and terms were knowledge, comprehension, application, analysis, synthesis, and evaluation; however, these terms have changed slightly over time. Yet these categories require individuals to demonstrate a different level of working knowledge of a topic.

With the advent of standards-based reform, the role of cognitive skill-particularly in the area of assessment-has become a much more explicit component of curriculum materials.

Over the past two decades, cognitive science has shown that individuals of any age retain information longer when they demonstrate deeper learning and make their own meaning with the content-using skills such as the abilities to conjecture, generalize, prove, and more-as opposed to only committing ideas to memory or performing rote procedures, using skills such as the ability to memorize or recall. In essence, Common Core created rigorous expectations to guide the instruction of students in all states that chose to adopt its standards.

These standards aimed to increase college preparedness and make students more competitive in the workforce. Policymakers, advocates, and practitioners hoped that Common Core would create greater consistency in academic rigor across states. In addition, with the classroom and homework aligned to these standards, many anticipated that students would graduate from high school prepared for college or career.

As of41 states and the District of Columbia have adopted and are working to implement the standards, although many of these states have modified them slightly. In this study, the authors evaluated homework to determine if it was aligned to Common Core standards in two ways: First, does it reflect grade-level content standards; second, does it require students to use skills similar to those required to demonstrate proficiency in a content area.

This multitiered approach is critical to evaluating alignment between standards and instruction-in this case homework. Instruction must teach content and help students develop necessary levels of cognitive skill. Curricula for each grade should include instructional materials that are sequenced and rigorous, thus enabling students to develop an understanding of all content standards. MTurk is a crowdsourcing marketplace managed by Amazon; it allows organizations to virtually administer surveys for a diverse sample.

A total of parents responded to the survey, and CAP analyzed homework assignments. The researchers dropped a total of 15 homework submissions from analysis either because the subject matter was not math or language arts-but rather, science, music, or social studies-or because the authors could not examine the specific content, for example, in cases where parents only provided a copy of the cover of a textbook.Research cited for younger children.

In each case, the pretest was used as the covariate. It looks at all of the individual studies done on a particular topic and summarizes them. Your Marzano Resources account gives you free access to research reports, the meta-analysis database, and more. For example, time on task, motivation, behaviour, teacher subject knowledge, feedback, home life, welfare, etc.

But, Hattie wavers on this major issue. Problem 5. The difference is in the SD they use. Glass shows that since the effect size is calculated by dividing by the standard dissertation pages see formulas above the standard deviation that is chosen can change the effect size in a significant way!

Glass gives this example p. Suppose that experimental and control groups have means and standard deviations as follows:. Simpson then insightfully explains that sampling from smaller populations is a major reason why effects for influences such as feedback, meta-cognition, etc are high while effects for whole school influences - class size, summer school, etc are low.

For Simpson's detailed argument see here. Kraft and Bakker et al. But, Hattie just ignores these issues and uses meta-analyses from abnormal student populations, e.

Also, he uses abnormal subjects from NON-student populations, e. One of the issues he emphasises is Hattie's use of students from abnormal populations. Some examples from the research Hattie used is Standley that Hattie used in Feedback. Standley reported effect sizes up to That sometimes is all right, but it can create a lot of double counting and weighting problems that play havoc with the results. For example, Hattie combined two meta-analyses of studies on repeated reading.

He indicated that these meta-analyses together included 36 studies. I took a close look myself, and it appears that there were only 35 studies, not 36, but more importantly, four of these studies were double counted. Thus, we have two analyses of 31 studies, not 36, and the effects reported for repeated reading are based on counting four of the studies twice each!

Students who received this intervention outperform those who didn't by 25 percentiles, a sizeable difference in learning. However, because of the double counting, I can't be sure whether this is an over- or underestimate of the actual effects of repeated reading that were found in the studies.

Of course, the more meta-analyses that are combined, and the more studies that are double and triple and quadruple counted, the bigger the problem becomes. I couldn't find marzano homework and practice of the original papers, so I couldn't thoroughly analyze the problems.

However, my comparison of only two of the vocabulary meta-analyses revealed 18 studies that weren't there. Better homework research. In a very telling study inwhich Marzano and Pickering conveniently omit, Cooper states that he found no significant relationship between homework and grades or between homework and scores on standardized test results for younger students.

The study found only a moderate increase in grades for older students doing homework Kohn, p. Marzano and Pickering also dwell on the marzano homework and practice of several meta-analyses on homework by Cooper, John Hattie and others.

Again, the problem with this type of homework research, which Kohn dutifully marzano homework and practice, is that the proponents of homework measure it against grades and test scores. Marzano homework effect size to evaluate the merits of homework against these useless measures only acknowledges that grades and tests are meaningful assessment tools, which they are not; this may be a debate for a future post. What Marzano and Pickering offer that is useful for teachers working at schools which mandate homework is the section of the EL article that supplies guidelines for homework.

For example, they suggest that it should be purposeful and involve parents in appropriate ways. Summarizing So, back to the new teacher who emailed me. Reading, as evidenced hereis really the best thing students can do outside of school.

This too, though, should be their choice, and it should never be connected to any grade or test. Mark Barnes is the Founder of Times 10 Publications, which produces the popular Hack Learning SeriesThe uNseriesand other books from some of education's most reputable teachers and leaders.

The pattern clearly indicates that homework has smaller effects at lower grade levels. Even so, Cooper b 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.

The Cooper, Robinson, and Patall 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 HomeworkCooper noted that homework should have different purposes at different grade levels: For students in the earliest gradesit should foster positive attitudes, habits, and character traits; permit appropriate parent involvement; and reinforce homework help and answers of simple skills introduced in class.

For students in upper elementary gradesit should play a more direct role in fostering improved school achievement. In 6th grade and beyondit should play an important role in improving standardized test scores and grades. One of the more contentious issues in the homework debate is the amount of time students should spend on homework.

The Cooper synthesis a 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 study reported similar findings: 7 to 12 hours of homework per week produced the largest effect size for 12th grade students. The researchers suggested that for 12th graders the optimum amount of homework might lie between 1.

Still, researchers have offered various recommendations. For example, Good and Brophy 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.

Cooper, Robinson, and Patall also marzano homework and practice a strong warning about too much homework: Even for these oldest students, too much homework may diminish its marzano homework and practice powerpoint or even become counterproductive. He added that when required reading is included as a type of homework, the 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.

Another question regarding homework is the extent to which schools should involve parents. Some studies have reported minimal positive effects or even negative effects for parental involvement. They recommended interactive homework in which Parents receive clear guidelines spelling out their role.

Teachers do not expect parents to act as experts regarding content or to attempt to teach the content. Parents ask questions that help students clarify and summarize what they have learned. Such assignments cause students and their marzano homework and practice powerpoint or other family members to become engaged in conversations that relate to the academic curriculum and thus extend the students' learning. Although research has established the overall viability of homework as a tool to enhance student achievement, for the most part the research does not provide recommendations that are specific enough to help busy practitioners.

This is the nature of research-it errs on the side of assuming that something does not work until substantial evidence establishes that it does. The research community takes a long time to formulate firm conclusions on the basis of research. Homework is a perfect example: Figure 1 includes synthesis studies that go back as far as 60 years, yet all that research translates to a handful of recommendations articulated at a very general level.

Meta-Analysis Database of Instructional Strategies

As research becomes more important in policy and practice, understanding them is becoming increasingly important. One constant question is how important a given effect size is. How big is big? An article by Hill, Bloom, Black, and Lipsey considered several ways to determine the importance of effect sizes. They noted that students learn more each year in effect sizes in the early elementary grades than do high school students.

They suggested that therefore a given effect size for an experimental treatment may be more important in secondary marzano homework and practice than the same effect size would be in elementary school. However, in four additional tables in the same article, they show that actual effect sizes from randomized studies are relatively consistent across the grades.

They also found that effect sizes vary greatly depending on methodology and the nature of measures. They end up concluding that it is most reasonable to determine the importance of an effect size by comparing it to effect sizes in other studies with similar measures and designs.
