This study investigates the use of using complexity theory--the study of nonlinear dynamical systems of which chaos and catastrophe theory are subsets--in the analysis of a non temporal data set to derive valuable insights into the functioning of university schools of business. The approach is unusual in that studies of nonlinearity in complex…

The use of computer-based automated assignment systems in economics has expanded significantly in recent years. The most widely used system is Aplia which was developed by Paul Romer in 2000. Aplia is a computer application designed to replace traditional paper-based assignments in economics. The main features of Aplia are: (1) interactive content…

The author discusses a method to produce a cluster of focused nursing research projects. Her method includes (1) focal topic identification, (2) development, (3) communication, (4) integration, (5) collaboration, and (6) balance. (CH)

Examples of problems based on the division of property mutually owned or mutually claimed are discussed. (DT)

It is common to find students believing that they have a high skill level in computer use yet this does not normally include proficiency in the use of computer packages for data presentation. This exercise develops team work in data collection, requires the production of a simple spreadsheet, and the exporting of the data from that into one or…

FIFTEEN DAILY DRILLS EMPHASIZING MASTERY OF BASIC NUMBER FACTS, SUCH AS ARITHMETIC OPERATIONS AND UNITS OF MEASUREMENT WERE CONSTRUCTED TO ENCOMPASS 7 PREVIOUSLY REPORTED ATTRIBUTES OF AN EFFECTIVE DRILL. ATTRIBUTES ARE MIXED DRILL, TIME LIMIT, INCREASINGLY DIFFICULT EXAMPLES, THOROUGH COVERAGE, FREQUENT AND SMALL AMOUNTS, VERBAL PROBLEMS,…

The author of this article, while recently working through some problem sets on determining volumes by triple integrals in cylindrical and spherical coordinate systems, realized that, although the textbook he was using included many interesting problems involving spheres, cylinders and cones and the increasingly complex solids that arose from the…

The study of preservice elementary teachers' knowledge of fractions is important because fractions are notoriously difficult to learn and teach. Unfortunately, studies of preservice teachers' fraction knowledge are limited and have focused primarily on division. The present study included all four operations to provide a more comprehensive…

The current study investigated the discreet task completion hypothesis presented by C. H. Skinner (2002) by investigating how the rate of interspersing affects performance on and preferences for academic assignments. Specifically, 70 sixth-, seventh-, and eighth-grade students were presented with four assignment pairs of multiplication problems.…

Presented are the six problems that were given to 120 secondary school students representing 15 countries at the 12th International Olympiad in Budapest, June, 1970. (JG)

Another way to divide a line segment discovered by Nathan Besteman is described along with Euclid's and the GLaD construction. The related projects and problems that teachers of geometry can assign to their students are also presented.

The results of an experimental study investigating the influence of problem familiarity on learning in a problem-based psychology course are presented. Participants worked with either a "familiar" or an "unfamiliar" version of the same problem. The following measurements were taken (1) a measure of problem quality as perceived by students, (2)…

An innovative concept of an electronic learning system has been established in an attempt to achieve a technology that provides engineering students with an instructive and affordable framework for learning engineering-related courses. This system utilizes an existing Computational Fluid Dynamics (CFD) package, Active Server Pages programming,…

This article describes a problem-centered curriculum for grades 9-12, using problem sets developed by a mathematics department and designed to take the place of textbooks. The students discover mathematical concepts in the context of the problems and activities in the materials.
