This bulletin is for those who sincerely want to understand the nature of a modern elementary school program. It presents a point of view, offers many illustrations of what happens in a classroom in the course of a school day, and interprets what children do, say, and learn as they work together with their teacher. Education should consist of meaningful, purposeful experiences if it is to be of practical use in everyday life, and if it is to have permanence. Such experiences that have real meaning for children and for which they can see an immediate use, rather than subjects as such, form the basis for teaching and learning in the modern elementary school. Through continuous planning, the curriculum of any group of children in any year becomes rich, broad, and practical. This bulletin describes a day with a group of real fourth grade students. Along with the story of what the children did, goes a running commentary explaining what these experiences mean, reasons why things went on as they did, some of the advance planning on the part of the teacher, ways in which the children and teachers planned together, and ways this group of nine- and ten-year olds are learning to meet and solve problems which confront them. Each situation in the story with its interpretation needs to be read in sequence before going on to the next one. Then there is a summarizing statement which points up implications for those who teach children and for parents who wonder about the quality of the school program, which may be different from the one they experienced.
