Computer Assisted Instruction(CAI①)
At the present time，there is a great deal of interest in the use of computers in education. The
use of computers in education has important benefits for both students and teachers.
Computers enhance② a student’s learning experience in many ways. First of all，the computer has the ability to accommodate③ individual differences in learning speed because the user is the one who controls the pace of the lessons. In addition，cai打头成语，because a computer is nonjudgmental④，the learner does not have to be afraid of humiliation⑤ when making errors. For example，because computers can repeat information over and over，the user can ask for many repetitions of a lesson without fearing a judgmental response about his ability to learn. Another advantage of CAI is that a computer can give a student immediate feedback⑥. It can tell the student why he is wrong as soon as an error is made，and it can even provide an appropriate hint as to⑦ how to figure out what the correct answer is.

“菜”字开头的成语有哪些？菜果之物 [ cài guǒ zhī wù ] ：比喻没有才能的人。出 处：汉·王充《论衡·状留》：“大器晚成，宝货难售，不崇一朝，辄成贾者，菜果之物也。”例句：他就是个菜果之物。
Not only do computers benefit students，they also make the teacher’s job easier. One advantage lies in⑧ the preparation of instructional materials. Schools and colleges can purchase educational computer programs that can be adapted to⑨ any learning situation. In addition，the computer offers numerous advantages to teachers in managing their classrooms. A computer laboratory can free the teacher to meet individually with students while the rest of the class is occupied with⑩ computer lessons. Finally，computers can help teachers keep students records and chart student progress，thereby cutting down on time-consuming paperwork.
With all of these advantages for both teachers and students，it is easy to see why there is so much interest in using computers in education.
