Delta-K Volume 18 Issue 3

Journal of the Mathematics Council of the Alberta Teachers’ Association

Volume 18 Issue 3, March 1979

This issue of delta-k was unfortunately delayed due to a car accident I was involved in. Also, after a six-week rest at the U of A hospital, I felt that a holiday was in order, which should be ended by the time you read this.

During the Easter week holiday in April, I will be taking a trip to Boston, Mass., as NCTM representative for MCATA. The report on that trip will come with next September’s delta-k and/or next October’s business meeting.

Those of you who applied for membership in NCTM at the time of our fall conference may wonder why your memberships have not yet been acknowledged. Unfortunately the process has been slightly delayed because of an error in quoted rates on the part of MCATA executive. The error has now been corrected, and memberships are being handled at the time of this writing.

Remember – an NCTM “name of site” will be held in October, in Calgary, where we will host a meeting that attracts participants from western Canada and the northwestern United States and a few from more distant parts of the continent.

I am very pleased to report that this and the next edition of delta-k will be filled with articles that are original submissions. This is very encouraging for me after having to frequently use reprinted articles because of a lack of original material. Also, most or all of the activities are more universal in nature.

I recently received a copy of Ergo, a paper published by Athabasca University, 14515 – 122 Avenue, Edmonton T5L 2W4. The copy was sent to me as publicity chairman of MCATA. After perusing the paper, I would say that many of you who are interested in broadening your education into areas of interest for personal satisfaction would find this publication useful. Since there is no information in the paper concerning subscriptions, I must assume that a letter to Ergo would get you on the mailing list, and thus, information on how to further your education through “TV” and “Radio” courses. I recommend the paper to all who desire home study and have the time and initiative to pursue it.
