I'm struggling to access the articles on the ACM website (http://portal.acm.org/portal) that is needed to complete assignment 1. Every time when I'm trying to view an article such as the one needed for question 2 "Valuing computer science education research?" by T Clear, a message is displayed indicating that (at the looks of it) I must register to access the article. Is there an easier way to access the articles, or must I register to access it, or am I doing some wrong some where?
Any ideas?
