This text employs the problem method, together with case dissection, to develop students' interest, increase their store of knowledge, and help them exercise analytical thinking and master basic contracts. Used in conjunction with the hornbook, Calamari & Perillo on Contracts, this methodology allows the students to explore a rich array of practical applications of the cases. UCC Articles 1 and 2 are included as appendixes. Many new cases in this edition were decided in the 21st century and involve current issues. Materials are streamlined to facilitate coverage in courses of fewer than 6 hours. These materials, together with the teacher's manual, provide exceptional guidance, especially for new teachers.
