Since its beginnings the Sandstone Tutorial has been 'field tested' with undergraduate students engaged in the challenge of learning sandstone petrology. At the earliest stages of development, input from these willing participants was invaluable in ferreting out programming flaws and errors in the text. Over the longer term however, the more important impact has been the influence of student users on the path of tutorial development. Are the explanations clear? Is a point made too often or not often enough? What new or enhanced features would be the most useful to add? What did you like the most? What stinks? Semester by semester, the answers that have come back to us from student evaluations have given us insights into how best to devote our development efforts.

Posted here are results from the student evaluations. Look through them to see how well our tutorial has served the students who have tested it and to get an impression of how this interactive development process has worked. This is a process we heartily recommend to anyone who is in the process of developing multimedia curriculum materials.

We are interested to gather information more widely, so if you have been using the tutorial in a classroom setting we want to hear from you! Just click the "Feedback" link at left.
