Delta-K Volume 23 Issue 2

Journal of the Mathematics Council of the Alberta Teachers’ Association

Volume 23 Issue 2, May 1984

This long-awaited edition contains some obvious changes in design, function, and content. Your comments “to the editor” would be appreciated. We hope to continue expanding the interest and appeal of delta-K to meet the changing needs of our readers.

Problem Solving

This issue explores a new approach, and we welcome Professor John Percevault as a regular contributor. Thanks to Ron for a problem type.
Computer Applications We also welcome back delta-K’s former editor, Professor George Cathcart, as a regular contributor to the “Microcomputer Corner,” which has an elementary emphasis. The results of his delta-K readership study are included as well.

Perspective

Many thanks to Professor Ediger for leading our thinking.

Letter to the Editor

I read John Curda ‘s article in the October 1983 issue of delta-K with great interest, and I enjoyed the manner in which he integrated the use of a microcomputer with the teaching of the coordinate plane.

I would, however, like to point out a small bug in the program listed on page 10. Statement 30 as written (FOR Y = l to 119 STEP-1) does not start the
“rocket” at the bottom of the screen and move it to the top as indicated in the description. However, by changing the statement to read “FOR Y = 119 TO l STEP-1” (as I’m sure John intended) , the “rocket” does indeed perform as it should.

delta-K agrees. Thanks for pointing this out.
