Student teachers given microteaching and traditional observation treatments were compared with a no-preparation control group. Results revealed that students taught by student teachers trained through microteaching achieved higher mean mathematics scores and demonstrated higher frequency counts of participation in classroom activities.

The use of a computer program written in BASIC to help prove a theorem in geometry is discussed. Ideas used in this example could be applied to writing programs for other geometric proofs. (MP)

Some examples of typical nonrelevant textbook problems on probability are followed by more complex problems pulled from the real world. The resource used in this report is Newsweek magazine; and is used to help demonstrate that from the very beginning, lessons on conditional probability can have relevance. (MP)

In this study with 132 secondary school geometry students, three significant aptitude by treatment interactions were found. Students with high reasoning scores and those with high processing scores profited more from the transformational treatment on point and line symmetry. (MP)

Objectives are defined in a manner that eliminates many of their attributes that have been criticized as being harmful or unappealing. Examples of objectives appropriate for secondary school mathematics are given and the relationship between classroom processes and objectives is discussed. (MK)

A basis is given for interdisciplinary activities for students studying transformational geometry. (MK)

The results of a school district's move to proficiency testing in mathematics are described and discussed. (MK)

This annotated bibliography includes activities with calculators in the areas of computational skills, geometry, measurement, number pattern recognition, and probability. (MK)

Communication of mathematical structure from curriculum developers to teachers and then to classes of secondary students was investigated. A high correspondence among the cognitive structure of curriculum developers, content structure, and teachers' cognitive structures, and between cognitive structure of a class and that of its particular…

Masters of worksheets containing flowchart activities are given. Sheets appropriate for levels 1 through 8 are included. (MK)

A team mathematics competition for students from a junior high school is described. A method for assuring that all ability levels are represented on each team is included. (MK)

Calculator-based activities are presented that may be used as the framework for a unit to replace much of the usual algebra material on exponential functions and logarithms. (MP)

The calculator is used to help students discover the Rule of 72 which is, in turn, used to investigate problems involving population, inflation, and energy reserves. (MP)

A description is given of a teacher's technique for teaching mathematics to mixed-ability groups. Examples from two lessons are given. (MK)

A discussion is given of the techniques for and advantages of using teaching aids based on the "rotogram." (MK)
