老师的不可替代性范文1with the development of new techonology and science,computer are widely used in education.therefore,some people think we dont need teachers anymore.i totally disagree with the above point.there is no denying that the computer bring great benefit to people and are of great help to students.computer can be programmed to simple digits of question,as the students answer these digits,their theoritical knowledge can be reinforced.however,in practice and learning of complex questions,computer can never replace the humain brain or surpass the human intelligence.computer only can tell your the final correct answer.but it cant provide students opportunity to think over it,which limited their creativity.teaching itself is an art rather than a machnican activity.therefore,teachers function can not be neglected.firstlly.computer only can do work according to the procedure fomulated previously.they can not answer all question in defferent way.teachers,however,can teach students according their attitute.some students who have better ability to accept knowledge,under teachersguidance,can be save time to gain other knowledge.secondly,facing the vivid dilivery from teachers,students can be improved their motivation and concentration.the effective communication operated by teachers not only can help students understand the knowledge,teachers also can teach students how to be a valuable people,which cant be done by computer.in addition,various teaching methods can help student absorb the knowledge rapidly.when students meet with the thorny question,teachers not only can explain it in different way,they also can show them the important deductive process.therefore,i would say teacher is the good compesation for flexiabilly lacting in the computer.i totally disagree with view that we dont need teachers anymore!范文2“Get up, boy, it is time to go to school.”“I dislike having get up early. I can take an on-line lesson at anytime I like.” It is a completely ordinary dialogue occurring in modern life. Yes, it is the computer, whose ever-accelerated updating brings about tremendous changes in our school lives. A typical application is Computer Assisted Instruction (CAI), which aids teacher to impart knowledge to student more efficiently by its multimedia characters. However, a vigorous debate over the issue whether or not teacher are by no means important in pedagogy field has intrigued the public. In my submission, the computer can be great help of teacher but they can never replace or surpass the position of teacher. I will offer the following reasons.Firstly, CAI are designed and programmed by human instructor. They only condense parts of teachers experience and intelligence. Moreover, being a successful instructor requires not just these factors but a wealth of experience and interpret new experiences using that information. The computer after all are man-made machine.Secondly, the progress of instruction is complicated and complex, and the educational achievement of CAI is limited. Some sorts of course, such as basic educational course( 想想什么课程用电脑教不好), are not necessarily to be expressed by the computer to reach productive effect.Finally, communications and interactions with teacher and computer are quite different. The latter is too impersonal, which ruins the pleasure of emotional exchanges. Sometimes gazing at the cold flickering screen is a disinteresting and tiring experience.Admittedly, though computer may help teacher to provide student with a richer and more effective learning environment, yet they can not substitute the position of teacher, not only today, but the future.范文3Computer, as the most powerful tool in 21 century, is widely used in education areas. Whether computers can instead of teachers become a controversial issue. From my point, I dont think computers can take the place of teachers.First and foremost, computer cannot communicate with students. Every human being has feeling. Teachers are not only teaching students knowledge but also showing their loves to students when they are teaching. How to have a conversation with others and how to take care of others can be learned from teachers. For example, teacher can take you to the hospital when you are sick. In comparison, computers cannot likely to it.Secondly, computers cannot help students when the get confused. Asking teachers is the best way to do when students get any quires. However, computers do not have this function. Study is a two-way process, teachers can excite students imaginations and fire their creations.Last but not least, computers cannot organize teaching activities instead of teachers. Take England as an example, students need to do a lot of practical experiments, especially in physics and chemistry. When they do these experiments, students usually work together as a group and discuss with teachers. Team work is a very important part to shape students
