A problem-solving network (flow chart) constructed for use in calculating titration is described. Points out that use of the network has greatly improved student confidence and skill in performing these calculations. (Author/JN)

Examples of four interviews are presented to serve as sample evidence in support of more comprehensive diagnostic procedures in assessing reliably and validly the weaknessess and strengths of learners. The search for computational errors is seen to go beyond standard paper and pencil tests. (Author/MP)

Conducted a study to determine the level of basic skills achievement among Ohio high school business education seniors. Found that these students lacked competency in general knowledge and in computational skills, basic English skills, and typewriting skills. (GC)

The computer is in the process of becoming an important aid to the teaching of statistics and probability at the middle and secondary levels. Examples show ways in which the computer can facilitate learning of mathematical concepts through tutoring, simulation, and computation. (JN)

A way to cast computational practice or review in a problem-solving context without moving into word problems is presented. The game described is viewed as an instructional tool that will allow pupils to explore and help them to develop forerunners of important mathematical problem-solving skills. (MP)

Three alternative methods of finding averages of two numbers are presented. (MP)

An introductory multiplication lesson, used successfully with second graders, is detailed. The method takes advantage of prior knowledge acquired in a geometry unit of study. The lesson is seen to have potential for other grades teaching multiplication for remedial work, and explaining the commutative law. (MP)

The use of pictures in the early instruction of doubles in basic addition is promoted. The process used in the Illinois University Mathematics Learning Clinic is detailed. Doubles are seen to be among the easy facts that children are capable of learning first. (MP)

This heat transfer problem requires students to analyze the feasibility of moving icebergs from the Antarctic to Saudi Arabia to provide fresh water. (BB)

This problem requires the student to calculate the volume of air breathed by a bicyclist every hour in Denver, Colorado, and New York City. (BB)

A calculator solution of a simple computational problem is discussed with emphasis on its ramifications for the understanding of some fundamental theorems of pure mathematics and techniques of computing. (Author/MK)

This is a preliminary report on research into computational errors made by six- and seven-year-olds. (Author/MK)

Discussed is the classical partition function for the ideal gas and how it differs from the exact value for bosons or fermions in the classical regime. The differences in the two values are negligible hence the classical treatment leads in the end to correct answers for all observables. (Author/DS)

A teacher describes the experiences of her fourth-grade students when using calculators during mathematics class. (MK)

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