Effect Size and Classroom Management

ClassThe Critical Role of Classroom Management Teachers play various roles in a typical classroom, but surely one of the most important is that of classroom manager. Effective teaching and learning cannot take place in a poorly managed classroom. If students are disorderly and disrespectful, and no apparent rules and procedures guide behavior, chaos becomes the norm. In these situations, both teachers and students suffer.

Teachers struggle to teach, and students most likely learn much less than they should. In contrast, well-managed classrooms provide an environment In which teaching and learning can flourish.

But a well-managed classroom doesn’t just appear out of nowhere. It takes a good deal of effort to create-?and the person who is most responsible for creating it is the teacher.

We live in an era when research tells us that the teacher is probably the single most important factor affecting student achievement-?at least the single most important factor that we can do much about.

To Illustrate, as a result of their study (1997) note the following: The results of this study will document that the most important factor affecting student learning is the teacher. In addition, the results show wide variation in effectiveness among teachers. The immediate and clear implication of this finding is that seemingly more can be done to improve education by improving the effectiveness of teachers than by any other single factor. Effective teachers appear to be effective with students of all achievement levels regardless of the levels of heterogeneity In their classes.

If the teacher Is Ineffective, students under that teacher’s tutelage will achieve Inadequate progress academically, sugarless of how similar or different they are regarding their academic achievement. (p. 63) [emphasis in original] Researcher Katie Haycock (1998) uses the findings of this study and others conducted by William Sanders and his colleagues (e. G. , Sanders & Horn, 1994) to paint a dramatic picture of the profound impact an Individual teacher can have on student achievement.

The point Is Illustrated In Figure 1 . 1, which depicts the differences In achievement between students who spend a year in class with a highly effective teacher as opposed too highly ineffective teacher. According to Figure 1 . , students in the classes of teachers classified as the most effective can be expected to gain about 52 percentile points in their achievement over a year’s time. Students in the classes of teachers classified as least effective can be expected to gain only about 14 percentile points over a year’s time.

This comparison is even more dramatic when one realizes that some researchers have estimated that students will exhibit a gain In learning of about 6 percentile points simply from maturation-?from growing one year older and gleaning new knowledge and information through everyday life (see Hattie, 1992; Cane & Davis, 1987). The least effective teachers, then, add little to the development of students’ knowledge and skill beyond what would be expected from simply growing one year older in our complex, Information-rich society. Figure 1. . Impact of Teacher Sanders and his colleagues, who gathered their data from elementary school students in Tennessee, are not the only ones to document dramatic differences in achievement between students in classes taught by highly ineffective versus highly effective teachers. Haycock (1998) reports similar findings from studies conducted in Dallas and Boston. I have come to similar conclusions in my work, although I have taken a very different approach from that used in the studies that form the basis for Haycock’s conclusions.

Whereas the studies conducted in Tennessee, Dallas, and Boston were based on data acquired from students over time, I used a research process called meta-analysis to synthesize the research on effective schools over the last 35 years (see Maroon, AAA, Bibb). That approach enabled me to separate the effect on student achievement of a school (in general) from the effect of an individual teacher. Figure 1. 2 illustrates my findings. Figure 1. 2. Effects of a School vs.. Teacher on Student Entering at 50th Percentile To understand the impact that a teacher can make, let’s consider each of the five scenarios in Figure 1. 2. (For a detailed discussion of how the computations in Figure 1. 2 were derived, see Maroon, AAA. ) As depicted in Figure 1. 2, if a student begins at the 50th percentile in mathematics, let’s say, and attends an average school and has an average teacher, her achievement will still be at the 50th percentile at the end of about two years. The student has learned enough to keep pace with her peers.

But what happens to that student if she attends a school that is considered one of the least effective and is unfortunate enough to have a teacher who is classified as one of the least effective? After two years she has dropped from the 50th percentile to the 3rd percentile. She may have learned something about mathematics, but that learning is so sporadic and unrecognized that she has lost considerable ground in a short time. In the third scenario, the same student is in a school classified as most effective, but she has a teacher classified as least effective.

Although the student entered the class at the 50th percentile, two years later she leaves the class at the 37th percentile. In contrast to the two previous scenarios, the fourth presents a very optimistic picture. The student is not only in a school classified as most effective, but also is in the class of a teacher classified as most effective. She enters the class at the 50th percentile, but she leaves at the 96th percentile. The fifth scenario most dramatically depicts the impact of an individual teacher.

Again, the student is in a school that is considered least effective, but she is with a teacher classified as most effective. The student now leaves the class at the 63rd percentile-?13 percentile points higher than the point at which she entered. It is this last scenario that truly depicts the importance of individual teachers. Even if the school they work in is highly ineffective, individual teachers can produce powerful gains in student learning. Although the effect the classroom teacher can have on student achievement is clear, the dynamics of how a teacher produces such an effect are not simple.

Rather, the effective teacher performs many functions. These functions can be organized into three major roles: (1) making wise choices about the most effective instructional strategies to employ, (2) designing classroom curriculum to facilitate The first role deals with instructional strategies and their use. Effective teachers have a wide array of instructional strategies at their disposal. They are skilled in the use of cooperative learning and graphic organizers; they know how best to use homework and how to use questions and advance organizers, and so on.

Additionally, they know when these strategies should be used with specific students and specific content. Although cooperative learning might be highly effective in one lesson, a different approach might be better in another lesson. Some general strategies that have a good research “track record” in terms of enhancing student achievement have been detailed in Classroom Instruction That Works: Research-Based Strategies for Increasing Student Achievement (Maroon, Pickering, & Pollock, 2001). The second role associated with effective teaching is classroom curriculum design.

This means that effective teachers are skilled at identifying and articulating the proper sequence and pacing of their content. Rather than relying totally on the scope and sequence provided by the district or the textbook, they consider the needs of their dents collectively and individually and then determine the content that requires emphasis and the most appropriate sequencing and presentation of that content. They are also highly skilled at constructing and arranging learning activities that present new knowledge in different formats (e. G. Stories, explanations, demonstrations) and different media (e. G. , oral presentations, written presentations, video presentations, Web-based presentations, simulations, hands-on activities). The third role involved in effective teaching is classroom management. This, of course, is the subject of this book. The following chapters detail and exemplify the various components of effective classroom management. Before delving into classroom management, however, it is important to note that each of these three roles is a necessary but not sufficient component of effective teaching.

That is, no single role by itself is sufficient to guarantee student learning, but take one out of the mix and you probably guarantee that students will have difficulty learning. Nevertheless, a strong case can be made that effective instructional strategies and good classroom curriculum design are built on the foundation of effective classroom management. As Long and Frye (1985) note in their book, Making It Till Friday: A Guide to Successful Classroom Management, it is a myth to believe that … Effective teachers can prevent all discipline problems by keeping students interested in learning through the use of exciting classroom materials and activities. The potential for problems exists beyond academics. Students experience difficulties at home which spill over into the classroom; students experience problems with peers during class breaks and in the classroom which often involve the teacher; and students experience mood changes which can generate problems, to name Just a few. Up. -4) Similarly, in their synthesis of the research, Edmund Emmer, Julie Sanford, Barbara Clement, and Jeanne Martin (1982) note that At all public school grade levels, effective classroom management has been recognized as a crucial element in effective teaching. If a teacher cannot obtain students’ cooperation and involve them in instructional activities, it is unlikely that effective teaching will take place In addition, poor management wastes class time, reduces students’ time on task and detracts from the quality of the learning environment. (p. 3) A Brief History of Classroom Management It is probably no exaggeration to say that classroom management has been a primary concern of teachers ever since there have been teachers in classrooms. However, the systematic study of effective classroom management is a relatively recent phenomenon. Here we briefly consider the major studies on classroom management. (For more detailed and comprehensive discussions, see Emmer, 1984; Brooch, 1996; and Doyle, 1986, 1990. ) Arguably, the first high-profile, large-scale, systematic study of classroom management was done by Jacob Cousin (1970).

He analyzed videotapes of 49 first and second grade classrooms and coded the behavior of students and searchers. Cousin’s findings are discussed in more depth in Chapter 5, but it is worth noting here that he identified several critical dimensions of effective classroom management. Those dimensions (among others) are (1) “whiteness,” (2) smoothness and momentum during lesson presentations, (3) letting students know what behavior is expected of them at any given point in time, and (4) variety and challenge in the seawater assigned to students. Whiteness” involves a keen awareness of disruptive behavior or potentially disruptive behavior and immediate attention to that behavior; f the four dimensions, it is the one that most consistently separates the excellent classroom managers from the average or below-average classroom managers. In 1976 Brooch and Version reported the results of one of the major studies in classroom management, up to that point, in a book entitled Learning from Teaching: A Developmental Perspective.

Their sample included some 30 elementary teachers whose students had exhibited consistently better than expected gains in academic achievement. The comparison group consisted of 38 teachers whose performance was more typical. Brooch and Version’s study, then, might be considered a imprison of exceptional teachers with average teachers. Although the study focused on a wide variety of teaching behaviors, classroom management surfaced as one of the critical aspects of effective teaching. Much of what they found relative to classroom management supported the earlier findings of Cousin.

Brooch and Iverson (1976) say this about their study: Much has been said . In the book about our findings concerning classroom management. Probably the most important point to bear in mind is that almost all surveys of teacher effectiveness report that classroom management skills are of primary importance in determining teaching success, whether it is measured by student learning or by ratings. Thus, management skills are crucial and fundamental. A teacher who is grossly inadequate in classroom management skills is probably not going to accomplish much. P. 27) A series of four studies conducted at the Research and Development Center for Teacher Education in Austin, Texas, marked a milestone in the research on classroom management. The first study involved 27 elementary school teachers. The second involved 51 Junior high school teachers. Results from the elementary school study were reported in Emmer, Version, and Anderson (1980) and Anderson, Version, and Emmer (1980). Results from the Junior high study were reported in Version and Emmer (1982) and in Sanford and Version (1981).

Both studies were descriptive and correlation in nature and identified those teacher actions associated with student on-task behavior and disruptive behavior. Again, Cousin’s earlier findings were strongly supported. One of the more significant conclusions from these studies was critical ingredient of a well-run classroom. The third and fourth studies, also conducted in the elementary and Junior high schools, respectively, examined the impact of training in classroom management techniques based on findings from the iris two studies.

The findings from these studies were reported by Emmer, Sanford, Clement, and Martin (1982); Emmer, Sanford, Version, Clement, and Martin (1981); and Version, Emmer, Sanford, and Clement (1983). As described by Emmer (1984), In the later two studies, the interventions occurred at the beginning of the school year and resulted in improved teacher behavior in many, but not all, management areas and also in more appropriate student behavior in experimental group classes as compared to control group classes … P. 17) Together, these studies set the stage or research and practice in classroom management for the late asses through the asses and resulted in two books on classroom management: one for the elementary level (Version, Emmer, & Horsham, 2003) and one for the secondary level (Emmer, Version, & Horsham, 2003); both are now in their sixth edition. To date, these books have been considered the primary resources for the application of the research on classroom management to K-12 education.

The Classroom Strategy Study conducted by Jeer Brooch (see Brooch, 1996; Brooch & Moccasin, 1992) was the next major study addressing classroom management. It involved in-depth interviews with and observations of 98 teachers, some of whom were identified as effective managers and some of whom were not. The study presented teachers with vignettes regarding specific types of students (e. G. , hostile-aggressive students, passive-aggressive students, hyperactive students) in specific situations.

Among the many findings from the study was that effective classroom managers tended to employ different types of strategies with different types of students, whereas ineffective managers tended to use the same strategies regardless of the type of student or the situation. One of the stud’s strong recommendations was that teachers should develop a set of “helping skills” to employ with different types of students. (Chapter 4 presents the implications of Brooch’s study in more depth. In spite of the profound impact of these various studies, classroom management received its strongest endorsement in a comprehensive study by Margaret Wang, Geneva Hearted, and Herbert Halberd (1993). They combined the results of three previous studies. One involved a content analysis of 86 chapters from annual research reviews, 44 handbook chapters, 20 government and commissioned reports, and 11 Journal articles. This analysis produced a list of 228 variables identified as having an impact on student achievement.

The second study involved a survey of 134 education experts who were asked to rate each of the 228 variables in terms of the relative strength of their impact on student achievement. The third study involved an analysis of 91 major research syntheses. The end result of this massive review was that classroom management was rated first in terms of its impact on student achievement. In summary, the research over the past 30 years indicates that classroom management is one of the critical ingredients of effective teaching.

Many studies and many books have been published articulating the specifics of effective classroom management. So what does this book have to offer that has not already been established? Certainly, this book reinforces the findings and suggestions from on a new research methodology not previously employed with the classroom management literature per SE. That methodology is meta-analysis. Meta-Analysis and Classroom Management Meta-analysis is an approach to research that was formally developed by researcher Gene Glass and his colleagues (see Glass, 1976; Glass, McGraw, & Smith, 1981) in he early asses.

In simple terms, it is a technique for quantitatively combining the results from a number of studies. Since its inception, it has been used extensively in the fields of education, psychology, and medicine. The powerful impact that meta- analysis has made on these fields of study is chronicled in the book How Science Takes Stock: The Story of Meta-Analysis by Morton Hunt (1997). In effect, this research technique has allowed us to construct generalizations about education, psychology, and medicine that were previously not available.

A logical question is, Why is the impel act of combining the findings from a number of studies so powerful? The answer is that any single study, no matter how well constructed, will have “uncontrolled error” influencing its outcomes. To illustrate, let’s consider a well- designed study that examines the impact of a specific classroom management strategy on students’ behavior. The study might randomly assign students to two groups-?one that uses the strategy (the experimental group) and one that does not (the control group).

The study might ensure that both groups do everything exactly the same except for the classroom management strategy that is being studied. Even with this level of tight control, the findings that come from the study might be influenced by uncontrolled error. For example, the way student behavior is measured might not be sensitive to behaviors that are important to the study; something might happen to the students in the experimental or the control group that is not related to the study but influences their behavior, and so on.

In fact, it is almost impossible to control all the error that might creep into a study. This is why researchers assign a probability statement to their findings. When researchers report that their findings re significant at the . 05 level, they are saying that there is a very small chance-?less than 5 chances in 100-?that their findings are a function of the uncontrolled error in the study. When researchers report that their findings are significant at the . 01 level, they are saying that there is as an even smaller chance that the findings are a function of uncontrolled error-?less than 1 chance in 100.

By combining the results of many studies, we can say with far more certainty than we can with a single study that certain strategies work or do not work. This concept is considered again in more detail in Chapter 2. To write this book, I undertook a meta-analysis that included the findings from more than 100 separate reports. I discuss, in non-technical terms, the results of that meta-analysis throughout the book, and they form the foundation for my recommendations. (See the Appendix for a more detailed discussion of the meta- analysis and Maroon, AAA, for a technical description. As shown in Figure 1. 3, my meta-analysis addressed four general components of effective classroom management: (1) rules and procedures, (2) disciplinary interventions, (3) teacher- student relationships, and (4) mental set. The remaining chapters of this book address these factors (along with some others) in depth. However, let’s briefly consider the meaning of the scores presented in Figure 1. 3. The fourth column components. The third column reports the total number of students involved in those studies.

The second column presents the average effect size for each of the four general components of classroom management. Figure 1. 3. Meta-analysis Results for Four Management Factors Factor I Average Effect Size I Number of Subjects I Number of Studies I Percentile Decrease in Disruptions I Rules and Procedures 28 | Disciplinary Interventions | -. 09 | 3,322 168 132 1 Teacher-Student Relationships | -. 869 | 1,110 14 1 31 Mental set | -1. 294 150215 140 1 Note: All effect sizes are significant at the . 05 level. I I-. 763 1626110 1 An effect size is a metric used in meta-analyses.

In the context of this book, it tells you how much of a difference in behavior you can expect between classes that effectively employ a given aspect of classroom management and classes that do not. To illustrate, let’s consider the average effect size for disciplinary interventions, as shown in Figure 1. 3. It is -. 909. This average was computed using the findings from 8 studies involving 3,322 students. An average effect size of -. 909 can be interpreted to mean that in classes where disciplinary procedures were used effectively, the average number of classroom disruptions was . 09 standard deviations less than the average number of disruptions in classrooms that did not effectively employ disciplinary procedures. One of the benefits of using the effect size metric is that we can translate it into a percentile change relative to the average number of disruptions that occur in a classroom. Let’s think of a disruption as any type of student behavior not sanctioned by the teacher. A disruption can be as innocuous as a student talking to her neighbor or as severe as a student being disrespectful to the teacher. So, for this example, we are not distinguishing the severity of disruptions, only the number of disruptions.

What does an effect size of -. 909 for disciplinary interventions tell us? In this case, an effect size of -. 909 translates into a decrease of 32 percentile points relative to the average number of disruptions in class. (For a discussion of how effect sizes are translated into percentile changes, see the Appendix. ) This means that the average number of disruptions in classes where capillary interventions are employed effectively will be at the 18th percentile in terms of the distribution of disruptions in classes where disciplinary interventions are not employed effectively.

To further understand the distribution of disruptive behavior, consider Figure 1. 4. Let’s assume that the average number of disruptions per day is 10 in classes where disciplinary interventions are not employed and that the standard deviation is 5. 0. This is depicted in the distribution on the right of Figure 1. 4. Given what we know about normal distributions, this implies that some days there will be many more disruptions than 10. In fact, we can predict that on some days the number of disruptions will be two standard deviations (or more) above the mean.

That is, on some days there will be 20 disruptions in these classrooms. Below the mean-?some days there will be no disruptions. In other words, the classes that don’t employ disciplinary interventions will have a few “low-disruption days” and a few “high-disruption days,” but the average number of disruptions will be 10 per day. Now let’s consider the distribution on the left of Figure 1. 4, which represents the classes that use disciplinary interventions effectively. Here the mean is 5. 46 and the tankard deviation is again 5. 0. On high-disruption days, these classes will have 15. 6 disruptions. On low-disruption days these classes will have none. Figure 1. 4. Effect Size of Disciplinary Interventions In summary, Figure 1. 4 indicates that classes that use disciplinary interventions will have their good days and bad days, as will classes that don’t. However, the average number of disruptions in classes that use disciplinary interventions effectively is substantially fewer than in classes that don’t. Over a year’s time, this decrease in disruptive behavior results in a significantly different atmosphere in the two types of classes.

Over a year’s time, classes that employ disciplinary interventions will have about 980 disruptions, whereas classes that do not will have about 1,800. The effect sizes reported in Figure 1. 3 make a strong case that effective use of classroom management techniques can dramatically decrease the disruptions in your classes. The results of my meta-analysis also demonstrate the impact of effective use of classroom management strategies on student engagement and student achievement (see Figure 1. 5). Figure 1. 5. Effects of Classroom Management on Engagement and Achievement Outcome I Average Effect Size I Number of Subjects I Number of Studies I

Percentile Increase I Engagement 1+. 617 178417 123 1 Achievement | +. 521 1 55315 120 1 Figure 1. 5 reports that classes in which effective classroom management techniques are used have engagement rates for students that are . 617 standard deviations higher than the engagement rates in classes where effective management techniques are not employed. This translates into a 23-percentile-point increase in engagement. Figure 1. 5 also indicates that classes with effective classroom management techniques reach achievement levels that are . 21 standard deviations higher than the achievement in classes without effective classroom management quenches. This translates into a 20-percentile-point increase in achievement. In other words, my meta-analysis indicates that, on the average, students in classes where effective management techniques are employed have achievement scores that are 20 percentile points higher than students in classes where effective management techniques are not employed. By a number of measures, then, effective classroom management has a powerful impact on students. Are Good Classroom Managers Born or Made?

Although the characteristics of an effective classroom manager are clear and even become an effective classroom manager. You might ask the question, Are effective classroom managers born, or can you become one if you are not one already? Fortunately, the answer to this question is that effective classroom managers are made. Good classroom managers are teachers who understand and use specific techniques. Awareness of and training in these techniques can change teacher behavior, which in turn changes student behavior and ultimately affects student achievement positively. Again, research evidence supports this assertion.

To illustrate, consider the research by Walter Borg and Frank Occasions (1982). In a study involving 34 elementary school teachers who were randomly assigned to experimental and control conditions, they found that (1) teachers who had been trained in the use of effective classroom management techniques (the experimental group) improved their use of those techniques when compared to a group of untrained teachers (those in the control group), and (2) the students of the teachers in the experimental group had fewer disruptions and higher engagement rates than those in the control groups.

One of the most promising findings from the research on becoming a skilled classroom manager is that apparently it can happen relatively quickly. For example, in their study of some 40 Junior high school teachers randomly assigned to experimental and control groups, Emmer, Sanford, Clement, and Martin (1982) found that teachers’ skills at classroom management could be significantly improved even by the simple intervention of providing them with a manual and two half-day work-shops.

As described by Emmer and his colleagues, The experimental treatment in the study was mainly informational, with no opportunity for feedback, directed practice, diagnosis with targeted intervention, or continued support and encouragement from staff or colleagues. Thus the treatment conforms to the type noted … As a minimal intervention . . (p. 65) Similar findings were reported for minimal interventions for elementary school teachers by Emmer, Sanford, Version, Clement, and Martin (1981).

How This Book Is Organized The seven remaining chapters in this book cover various aspects of classroom management in greater detail. Chapter 2 addresses classroom rules and procedures. Chapter 3 discusses disciplinary interventions. Chapter 4 addresses teacher-student relationships, and Chapter 5 addresses mental set. Chapter 6 provides a different respective on classroom management. Instead of considering what the teacher can do to enhance the management of the classroom, it considers the role of the student in the effective management of the classroom.

In effect, it discusses student responsibility for classroom management. Chapter 7 considers how to begin the school year in a way that ensures a good start to management. Finally, in a shift from the individual-classroom perspective of Chapters 2 through 7, Chapter 8 considers the role of the school in the business of management. Each chapter begins with a consideration of the research and theory. Next, specific programs that are particularly strong in a given aspect of classroom management are considered.
