Suitable for secondary school students, the workbook provides flowcharting activities to help students understand the logical steps used in problem solving. Before applying the flowcharting procedures to mathematical problems, students are first introduced to familiar non-mathematical problems such as sharpening a pencil or eating peanuts. Section…

The teaching of non-numerical flow charting to all pupils is advocated as a means of preparing students for decision making. Several sample problems are provided. (SD)

Discusses the development and use of flowcharts to involve students in the major stages of experimental design and hypothesizing. The progress of stages attempts to simplify the complexity involved during problem-solving in science investigations. Several illustrative flowcharts are included. (JN)

Presents a classroom technique designed to aid student understanding of science that involves a flow chart of the scientific method. Affords a conceptual framework for organizing many research concepts taught in introductory science classes. Contains 19 references. (DDR)

An activity for secondary schools is presented and discussed which may be explored with a programmable calculator. The activity is non-standard and could not be easily explored without the use of a programmable calculator. Related activities are also discussed. Flow charts and programs for different programmable calculators are presented. (MP)

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)

The application of the programmable calculator to evaluating complicated formulas is illustrated by considering the formula for finding the area of any triangle when only the lengths of the three sides are known. Other advantages of the programmable calculator are discussed such as freeing the student to explore more challenging problems and…

Three teaching ideas are presented: a way to solve problems based on the attitude to the hypotenuse in a right triangle, some interesting applications of percentages in determining pay raises, and a flowchart guide for reducing polynomials. (MP)

Presents a method to enhance the teaching of computer programing to secondary students that establishes a connection between logic, truth tables, switching circuits, gating symbols, flow charts, and pseudocode. The author asserts that the method prepares students for thinking processes related to programing. (MDH)

The message of this article is that there are many types of problems ordinarily requiring advanced techniques or special insight to solve which can now be done as simple programming exercises on inexpensive programmable calculators. Several examples appropriate for the secondary school curriculum are given. These are: (1) evaluating polynomials;…

A problem from number theory is used to illustrate the use of the computer and programable calculators in solving problems. Programs are included. (MP)

The probability of winning the contest was analyzed, with the mathematical solution and a computer simulation given. A flowchart and computer program are both included. (MNS)

Describes two studies conducted in the United Kingdom that tested the effectiveness of flowcharts versus contingency statements for solving complex problems, one with secondary school students and one with senior citizens. Two measures of effectiveness are considered, speed and accuracy; and the effects of practice upon using the materials are…

Problems were presented to 13 university students in which letters were to be added or subtracted (e.g., B + D = ? or F - ? = D). After each problem, each subject gave a retrospective protocol indicating the way in which the problem was solved. Models of performance by each subject in each experimental session shared major properties; choices by…

Hierarchically organized knowledge about actions has been postulated to explain planning in problem solving. Perdix, a simulation of problem solving in geometry with schematic planning knowledge, is described. Perdix' planning knowledge enables it to augment the problem space it is given by constructing auxiliary lines. The planning system also…
