Educational organization rests to some extent on psychological views about learning, but explicitly it is concerned with the grouping of pupils for educational experience and instruction.

Pupils in general are organized by age into what are usually termed grades, classes, or forms. Each school is also usually either comprehensive (containing students pursuing various academic, commercial, and vocational curricula) or based on the so-called dual plan (containing only students pursuing a particular curriculum). In some countries, the dual system is actually tripartite: there may be schools for classical academic study, schools for technical or vocational study, and schools for more generalized, “modern,” diversified study. Whether comprehensive or dual-plan, schools frequently have some kind of streaming or multitracking whereby students are grouped according to ability so that there are separate classes for the less able and the more able.

Grading and streaming have come in for much criticism. There is a rigidity in the two systems that causes some educators uneasiness, particularly since total education is seen as more than achievement in school subjects. Some countries, notably the United States, have made a start in trying to solve this difficulty by introducing the nongraded school, in which grades are abolished and students are placed individually in “phases” for each subject, through which they progress at their own pace. A similar solution has been to ungrade students for certain basic subjects, such as mathematics and native language, but to have them rejoin their age peers for other school activities. In such systems there is, nevertheless, a kind of grading by intellectual ability, and egalitarians are apt still to be suspicious of them. There is scarcely any clear evidence of the effectiveness of the wholly nongraded system. It would seem probable that the optimum organization may be to combine grading with nongrading. Although that will involve constructing complex timetables, it will also offer the advantages of other, more rigid systems without introducing too many of their disadvantages. For one thing, retaining some grouping by age seems important as a link to extramural activities, in which age peers tend spontaneously to come together.

The modern interest in resources for learning has led to the concepts of general-purpose classrooms, open-plan teaching, and team teaching. The idea of general-purpose classrooms starts from the assumption that the school curriculum can be divided into a few large areas of allied intellectual interests, such as the humanities, languages, and sciences. The total resources available for teaching in each of those areas, including teachers, are then made available in one common teaching space, and ordinary classroom and lesson-period divisions disappear, to be replaced by a real mobility between teachers and learners as they make use of the different resources available, including library and laboratory facilities and various educational aids (see below Instructional media). In the infant and primary schools, similar ideas are introduced in the open-plan system. At both the primary and the secondary levels, however, there is insufficient evidence on the effectiveness of the systems. The attitude and action of teachers remains the strongest factor, and they may still require some privacy for their teaching.

Team teaching represents an attempt to make better use of every teacher’s potential in any subject area, to create a flexible learning situation, and to make nonstreaming more effective. For example, the normal class of 30 pupils with an individual subject teacher is replaced by a larger group of pupils and a team of teachers, who pool their efforts. Although the team plan may take several forms, it generally assumes some variety of the following elements: (1) large-group instruction, in which the total complement of some 50 to 150 students in the program is periodically taught by one teacher (either the same teacher or several teachers in rotation) in a lecture hall; (2) small-group instruction, which alternates with large-group instruction so as to allow small numbers of students and a member of the teaching team to discuss, report, and exchange ideas; (3) independent study, whereby students are given individual projects or library work; and (4) team planning sessions, in which, daily or weekly, the teachers plan, coordinate, report on, and evaluate their programs. The presumed benefits of team teaching are that it makes better use of each teacher’s individual interests and strengths; that it avoids unnecessary replication, particularly in such basic subjects as native literature, in which ordinarily several classes led by different teachers cover the same ground; and that teaching in front of one’s colleagues is a beneficial practice providing some evaluative feedback. Also, it is said that the less able children do not feel so segregated as in ordinary streamed classes; although they may gain little from the large-group sessions and individual projects, they seem to make real progress in the small seminar groups, without becoming overaware of their more limited capabilities. The reasons for that are obscure. In any event, the most obvious advantage of team teaching is its flexibility, in affording a great variety of possible combinations of student groupings and of educational resources. The major problem is that team teaching cannot be used in all subject areas. Although it may be useful in such areas as the humanities and the social sciences, its provision for lecture-size audiences does not aid the teaching of such subjects as mathematics, in which there are too many individual differences in ability. The same is true of arts and other subjects. Furthermore, without expert leadership, seminars are apt to degenerate into scenes of rather woolly discussions.

The grouping of children by ability, though still practiced, remains a problem. Formal tests are used to separate students according to their ability, and many people feel that separations by such means are neither reliable nor socially desirable. Even with regard to separating the intellectually disabled, there is growing opinion that, wherever possible, such children should be given basic instruction in special centres and remedial classes in schools for normal children. Disabled and normal children would thereby share much of their education. Separation of the sexes has also declined in most countries, as the mixing of girls and boys has come to be recognized as healthy and socializing.
