Description

The computer-assisted homework consists of over 40 individual assignments for the introductory sequence of college physics courses. Each of these individual assignments contains several problems that relate to one or more fundamental principles. Where appropriate, the programs use diagrams, animation, sound, and simulations based on numerical methods.

When wrong answers are entered, students are usually shown how to do the problem correctly. A random number generator changes the values in a problem or changes the problem type the next time through the same assignment so that a sudent repeating an assignment doesn't get the exact same problems. At CBU, student scores are recorded and used in determining a student's final grade.

We offer ungraded versions of the programs to the general public free of charge. In these versions, the score for a particular assignment is displayed but not recorded. These ungraded assignments are designed to help the student practice doing physics problems. The programs should work on any pc that is running a version of Windows. Instructors that want an on-line graded homework system should browse the many options available from text book publishers.

The programs were written by Dr. Johnny Holmes and Dr. John Varriano using TrueBasic. They are fully executable programs (*.exe). No additional software is necessary.

List of Programs

The programs are grouped into the following seven volumes. The list of programs on each volume can be viewed by clicking on the volume number. Static screen images from programs can be viewed for those programs that are highlighted in the volume lists.

Vol. 0: Review of Mathematics
Vol. 1: Motion and Newton's Laws Vol. 2: Energy and Rotations
Vol. 3: Electricity and Magnetism I Vol. 4: Electricity and Magnetism II
Vol. 5: Light Vol. 6: Relativity and Radioactivity

You may obtain these programs free of charge, provided you fill out a short form.
