What are microcomputer-based laboratories (MBLs) for? An example from introductory kinematics.
September 22, 2002... Teaching physics in the laboratory, and more specifically, the use of computers in the physics laboratory is a question of worldwide concern. In this article the authors shall try to validate the use of microcomputer-based laboratories (MBL),...

The effect of web-based homework on test performance in large enrollment introductory physics courses.
September 22, 2002... This study compares the effect of web-based homework (WBH) and paper-and-pencil homework (PPH) on student achievement as measured by exam performance. Various offerings of two large introductory physics sequences were examined over a three-year...

Learning chemistry through the use of a representation-based knowledge building environment.
September 22, 2002... Many students leave high school chemistry courses with profound misunderstandings about the nature of matter, chemical processes, and chemical systems. The ChemSense project is addressing this problem through a multidisciplinary program of...

Computers for mathematics: theoretical solution versus constructive solution.
September 22, 2002... In this article the role of technology and its pivotal--in many cases, indispensable--role in solving real-world problems is underscored. It is demonstrated that the existence of a solution to a problem, which has been proven by any means, does...

Object-oriented implementation of the backpropagation algorithm.
September 22, 2002... The Error-Backpropagation (or simply, backpropagation) algorithm is the most important algorithm for the supervised training of multilayer feed-forward Artificial Neural Networks (ANN). It derives its name from the fact that error signals are...
