In 1994 the National Education Commission on Time and Learning found the issue of how time is spent in schools to be a matter of urgency. Likewise, the National Education Association reported that "across the nation in schools and districts engaged in transforming schools into more effective learning communities, the issue that has emerged as the most intense and the one that universally dominates discussion is time" (p. 9). To spend the "time budget" more wisely, schools use a variety of scheduling arrangements. Discussed here are the various types of schedules that schools use to make optimum use of the school day.
Historical Background of Scheduling
In the early nineteenth century, teachers typically had a limited education and were expected to function well in all subject areas. Staff at all levels taught any subject at any time of the day. In the late 1800s, the Carnegie unit –comprised of approximately fifty-minute class periods in which a single subject is taught, and for which teachers specialize in particular subject areas–became the most frequently used scheduling format. J. Lloyd Trump's An Image of the Future, published in 1958, caused schools to experiment with ungraded instruction, long periods of independent study, and large group instruction. The plan failed, however, partly due to the large amount of unstructured, independent study time for students.
Other scheduling experiments have also failed. In the 1970s, the notion that flexibility in scheduling is beneficial to staff and students led to the Open School concept. Divisions between classrooms in elementary schools were eliminated and students were able to progress at their own speed, moving from one grade area to another. During the 1960s and 1970s, some schools modified the traditional seven-period day, breaking the day up into twenty-minute modules and calling the plan modular flexible scheduling. Neither plan took hold.
In the 1970s, with flexibility continuing to be a priority, fluid block scheduling became popular and successful. This scheduling pattern allots a block of two to three hours to teams of teachers from various subject areas, allowing teachers to schedule instruction according to student needs. Another flexible scheduling alternative that began in the late 1980s and continues in popularity is the zero period schedule. Designated courses begin an hour earlier than the regular school day, allowing some students to leave an hour earlier or enroll in an extra class.
The 1989 publication of Turning Points, by the Carnegie Council on Adolescent Development, brought major changes for middle-level schools. Recognizing that junior high schools were simply mirror images of high schools, the council recommended that schools be reconfigured to fit the developmental needs of young adolescents. Thus, various forms of block scheduling and interdisciplinary teaming took hold in middle schools, and later in high schools as well. With block scheduling, teachers are given longer periods of time–usually ninety minutes–to work with students. Interdisciplinary teaming is a popular arrangement where a group of teachers (usually four or five) works with 125 to 150 students, essentially creating a school within a school. Interdisciplinary units of study help students' understand the connections between subjects. Teaming is sometimes combined with block scheduling.
Throughout the history of school scheduling, the need for flexibility and the need for teachers to work cooperatively for the benefit of students are recurring themes. These themes impact educators' scheduling choices.
Selecting a Schedule
Selecting an appropriate school schedule involves some fundamental assessments, including examining what teachers are doing and determining if classroom instruction is improving student achievement. When teachers make instruction optimally effective for students, it is appropriate to consider how use of time could further enhance learning–the schedule must support, not drive, the instructional program. As teachers become more innovative and experimental in their classroom activities, they adopt flexible and cooperative approaches that demand new organizational arrangements.
What students need is another consideration when choosing a schedule. For example, elementary and middle school students are restless, have short attention spans, and require frequent physical movement, and frequently changing settings allows for such movement. Elementary students need close relationships with adults, and thus need to remain in the care of one teacher, not five or six, during a school day. High school students need opportunities to explore more specialized areas of interest, and thus require a wide variety of courses from which to choose.
Other considerations can impact scheduling. Whether or not to group students by their ability levels is an issue on which parents and teachers do not always agree. If improving student behavior is a priority, reducing the number of times students change classes and interact in the halls is considered. Teachers' preferences for teaching assignments and planning periods, assigning enough lunch periods to accommodate students, arranging for televised classes, including courses that are popular (or eliminating outdated ones), and parents' attitudes about courses all impact scheduling decisions.
Scheduling models are generally described in terms of the amount of time students spend in a specified classroom. The most frequently used scheduling models are (a) the traditional, self-contained classroom, (b) forty-five to fifty-minute class periods, (c) a variety of configurations of block scheduling, and (d) teaming.
Self-contained classrooms. Typically seen in elementary schools, self-contained classrooms are settings where a single teacher is in charge of instructing twenty to thirty students for the major portion of the day. The advantages of self-contained classrooms include strong student-teacher and student-to-student relationships; flexibility in time spent on subject areas; and buildings designed for self-contained classes. The cost of this arrangement is in the loss of high-quality instruction for some subject areas, and possibly in all subjects, if the teacher is not a master of instruction and discipline.
Forty-five to fifty-minute class periods. The traditional high school and middle school schedule, shown in Figure 1, is of fixed length and classes meet the same hour each day. Benefits include daily drill and practice for such subjects as mathematics; students miss only one period in each subject when they are absent; and schools are likely to be similar when
students transfer from one to another. The disadvantages are that periods are too short for extended teaching activities such as science labs; there is not enough time to form quality relationships; discipline problems occur during the frequent passing periods; teachers teach 150 or more students each day; and the class period, not the instruction, determines activity length.
Block scheduling. Of the many configurations possible under the umbrella of block scheduling, the alternate day block schedule–sometimes termed the A/B block –is the most popular (see Figure 2). Classes meet each day for ninety minutes. Four classes meet on A days, and four meet on B days, with days of the week alternating as A or B. Several combinations of forty-minute and longer periods are possible. For example, with the fluid block schedule three periods a day are ninety minutes in length and two are forty minutes long, allowing for such subjects as mathematics to meet daily, while giving subjects such as science longer periods.
Some other forms of block scheduling are available but infrequently used. The semester block schedule allows students to attend just four classes for ninety minutes each day for an entire semester. The following semester students enroll in another four classes. The 75-30-75 plan, proposed by Robert Canady and Michael Rettig, divides the school year into three blocks of time: two seventy-five-day terms and a thirty-day term. During each seventy-five-day term, the school day includes three 112-minute block classes and one forty-eight-minute period. The thirty-day term offers students the opportunity to study one core course intensively. The trimester plan divides the school year into three, rather than two, semesters, and combinations of forty-five-minute and ninety-minute periods are possible. A drawback to all such variations is coordination of schedules for transfer students.
Canady and Rettig designed the parallel block schedule for elementary and middle schools. To reduce class size for key subjects such as reading and mathematics, small groups are rotated out for special education and talented and gifted classes, as well as for computer labs. Advantages of all types of block scheduling arrangements are:
- The number of subjects students take yearly is increased
- Time is available for developing more meaningful relationships
- Daily homework is assigned for half as many classes
- Passing periods are reduced, which may decrease discipline problems
- Teachers have fewer students to instruct in one day
- Opportunities are available for instructional creativity and in-depth learning
Some disadvantages are:
- Some subjects require daily drill and practice
- New instructional methods are necessary to make full use of longer periods
- Staff, central office, parent, and community support must be sought
- An increased staff is necessary and costly
Teaming. For years, elementary school teachers have acknowledged the value of integrating instruction to blur the lines between subject areas and stress the links between fields of knowledge. A shift toward a more student-centered approach to educating middle school students became more prevalent with the publication of Turning Points in 1989. Consequently, interdisciplinary teams are formed and provide continuity for group membership and instruction, similar to what exists at the elementary level. When teaming, two or more teachers of two or more subjects share a common group of students. Students can be grouped and regrouped during the shared time period, depending on the activity. Interdisciplinary teaming requires more complex configurations because instruction is coordinated across subjects to offer a less fragmented and more relevant curriculum. Thematic units of instruction are the usual planning tools. The flexibly blocked team, sometimes termed the team block schedule, incorporates not only the sharing of a common set of students and the opportunity for a coordinated curriculum, but also the flexibility of long class periods, which provide optimum use of the instructional time. Advantages to teaming are:
- Teachers get to know students personally
- Studies report improvement in thinking and learning skills
- Stable friendships can develop
- Class time can be used flexibly
- Changes within the team do not interfere with other teams' plans, such as a scheduled field trip
- The team collectively assumes responsibility for each student's learning and meets with parents as a group
The disadvantages are:
- Ability grouping is more difficult
- Interpersonal problems are intensified
- An adjustment period is required for teachers
- Staff training on integrated instruction is necessary
- Support from central administration, parents, and community must be obtained
- Buildings are not designed for division of classrooms according to teams.
All types of schedules require staff training. For example, teachers need to be able to teach to a variety of learning styles, teach higher-order thinking skills, use problem-solving techniques, and use technology in the classroom. In order to vary instruction during the longer block-scheduled class periods, teachers should additionally be trained to move beyond lecture, drill, and practice and include cooperative learning, learning centers, inductive learning, the use of manipulatives, and student-conducted experiments. When teamed, teachers should understand interdisciplinary instruction and be able to address issues that arise when a small group of students and teachers interact intensely with one another. Training can include team building and teaching, consensus building, conflict resolution techniques, and interdisciplinary instruction.
Whatever the scheduling model, finding a schedule that works best for teachers and students while satisfying community needs is important. If instruction and student achievement drive choices, such satisfaction is more likely to be achieved.
