Prentice Hall’s modern on-line homework and java learning labs for Introduction to Java Programming, 6/e  by Daniel E. Liang. 

GOAL (Gradiance Online Accelerated Learning) was created with the intent to change homework from a traditionally one-sided, sometimes frustrating, exercise into a truly interactive, online tutoring system that makes learning a more efficient and effective experience.  GOAL's function is to offer immediate assessment and feedback to the student through two kinds of assignments: homework and Java programming labs.  

• On-line homework consists of a set of questions that instructors may assign.  The questions are phrased as problems for a student to solve completely.  However, instead of having the student write down a solution, the student's knowledge is sampled, repeatedly if necessary, by a multiple-choice question. This methodology, the proprietary technique called “root questions,” distinguishes GOAL from other on-line homework programs. 
•  The Java programming labs portion of GOAL also takes an innovative approach to engaging students.  GOAL programming labs are more than just compilers or syntax checkers.  GOAL tests submitted code for both syntactic and semantic errors so that  students no longer “write to the test,” but are compelled to write code that works in all cases, not just the test cases.

 Prentice Hall is proud to offer such a ground-breaking learning toolset.
