Criticisms of the printed medium of instruction are made with the implication that a system which relies upon one medium of instruction is unlikely to provide either the kind of resource or the answers a teacher needs. (MN)

A Keller-plan, mathematics laboratory-based review program initiated in response to the problem of forgotten relevant mathematical skills, new and different terminology and gaps in mathematics backgrounds, is described. (MN)

Introducing variety into the high school mathematics classroom by using activity units and small groups work is discussed. (DT)

The most significant feature of this program is the sorting of students into small groups managed by student teachers. This serves the purpose of teacher education as well as student remediation. (MP)

A mathematics center is described, including a list of basic equipment for the laboratory. The main focus of the article is on teaching method. Three discovery-oriented procedures are noted, and successful activities and materials are discussed. (DT)

A scheme for diagnostic teaching is discussed, and aspects of the approach are illustrated from three teaching experiments. Instruction that aims towards free and relaxed discussion of single points of difficulty or conflicts and towards pupils seeking to learn how a particular system works is promoted. (MP)

Students' misconceptions in mathematics and how teaching may be directed to diagnose and eliminate these misconceptions are discussed. Four main types of misconceptions during problem-solving are noted. It is also noted that the basic mathematical processes of generalizing, representing, and explaining are used in selected student self-help…

A series of worksheets dealing with the Morse Code are presented. The material incorporates vocabulary knowledge, substitution, and patterns, and is viewed suitable for any student. The initial activities are followed by three optional challenges. Pupils can develop a basis for reflecting on mathematical symbols and words. (MP)

A description of mathematics as a game'' with a statement of rules and an investigation of the consequences is applied to a finite geometry problem concerning sets and subsets of club members and lunches. (DT)

Mathematics teachers are seen working in a context affected by three major revolutions. The first, mass secondary education, has been dealt with. The second, technological revolution, is taking place. The third, humanizing mathematics, is viewed as heaving into sight, and seen as possibly a greater upheaval than the others. (Author/MP)

The role of the teacher in discovery teaching is discussed; examples of non-directed and of directed discovery methods are provided. (DT)
