Wow – that is quite the rumor! Do you know where you heard that one? I'd like to head that off at the pass!
No, there are no plans to change CS1315 at all! We will be using a new book, but only because we're finally getting a nationally-published version (from Prentice-Hall) rather than having a custom book produced. Yes, we'll still use JES.
What starts next semester is CS1316 – the new SECOND course. CS1316 has CS1315 as its pre-req, and it meets the pre-req for CS1322.
Seriously – if there's an advisor who's misinforming students, I'd like to know and address it.
