【正确答案】CAI refers to computer-assisted instruction, which is the use of a computer in a teaching program. They may include:
a)A teaching program which is presented by a computer in a sequence. The student responds on the computer, and the computer indicates whether the responses are correct or incorrect.
b)The use of computers to monitor student progress, to direct students into appropriate lessons, material, etc. This is also called computer-managed instruction.
CAL refers to computer-assisted learning.CAL and CAI deal with teaching and learning in general. The first kind of CAL programs which were developed reflected principles similar to programmed instruction. The computer leads the students through a learning task step-by-step, asking questions to check comprehension. Depending on the student's response, the computer gives the student further practice or progresses to new material. In more recently, CAL courseware students are able to interact with the computer and perform higher-level tasks while exploring a subject or problem.

【答案解析】[解析] 本题考查CAI(computer assistant instruction计算机辅助教学)和CAL(computer assistant learning计算机辅助学习)的区别。前者注重于教师教的问题，后者强调在教和学两方面使用计算机，帮助学习者达到教学目标。
