Opis

Practical work in astronomy at elementary and intermediate levels presents a difficulty for teachers. Unlike laboratory sciences, astronomy does not easily lend itself to bench experiments. Astronomical photographs supply an answer; they show what celestial objects actually look like, and are at the same time capable of being used to set problems relevant to the course work.

Recenzje

"This book will undoubtedly prove to be an admirable adjunct to class tuition which is normally greatly restricted in scope as practical work in astronomy at elementary and intermediate level presents difficulty for teachers."
-Spaceflight, February 1991

"This book fills a need in astronomy for more advanced resources using real data and it will appeal to teachers as well as students."
-GNOMON

"I don't hesitate to recommend the book …"
-Darrel Hoff, Sky and Telescope, September 1991

"The book is a pleasure to read … the book is strongly recommended as a text to accompany introductory astronomy courses …"
-D.K. Aitken, Australian & New Zealand Physicist, vol. 28, no. 6, June 1991

"… attractively presented … will be enjoyed by sixth-formers, students at college, and the amateur astronomer."
-J. Br. Astron. Assoc., 101, 3, 1991
