Getting Started with GradianceIndexIntroductionGradiance (also known as GOAL, for Gradiance Online Accelerated Learning) is a system pioneered by Prof. Jeffrey Ullman. It offers many advantages over traditional written assignments. Given one "root question," Gradiance can generate different instances of this question. Therefore, you are permitted to test yourself on the same root question as many times as you like, and receive immediate feedback for each attempt. Gradiance also has a lab component that automatically tests your solutions on different inputs. Hence, it avoids the shortcoming of the traditional submit-and-then-wait-for-grades assignments where one error in understanding can permeate solutions to multiple problems and does not get rectified until much later. We encourage you to continue testing on each topic until you complete the assignment with a 100% score. For each Gradiance problem set or lab, your score is the highest score achieved as of 11:59PM on the due date. Purchasing accessYou can purchase Gradiance access online at https://register.pearsoncmg.com/reg/buy/buy1.jsp?productID=37277. (The last time I check the price was $34.00.) You will get a 6-word access code. Keep it safely for your records. Another way to obtain Gradiance access is to purchase a valuepack which bundles the book together with a Gradiance access kit. The combined price might be cheaper. You will find a 6-word access code inside the kit. If you are buying a used valuepack, beware that the access code might have already been used. If that is the case, you will not be able to sign up with the access code. Signing upPoint your browser to http://esminfo.prenhall.com/goal/students.html, and register for "Garcia-Molina/Ullman/Widom: Database Systems: The Complete Book, 2e." Follow the instructions. (If you purchased access online, you probably have already created a Pearson Education account.) During the registration process, enter the access code that you obtained earlier. Logging inPoint your browser to http://www.gradiance.com/pearson and follow the instructions to log into Gradiance. If this is the first time that log in, enter the class token 4106477C to sign up for CPS 116. From this point on, CPS 116 will be listed automatically as one your classes (at the top of the Web page) as you log in. Click on CPS 116 to continue. Additional informationYou might want to read this Gradiance Guide for Students before starting your first Gradiance assignemnt. This document is very short and provides very useful hints on how to approach Gradiance-style multiple-choice questions. Note that Section 1 of the guide is outdated; please refer to the updated sign-up and login instructions on this Web page. |
