Electronic Teaching
The potential of closed-circuit television and other new electronic teaching tools is so great that it is fascinating to visualize" the school of tomorrow".
Televised lessons will originate from a central building having perhaps four or five master studios.The lessons will be carried into classrooms all over a city,or even an entire country.
After a televised lesson has been given,the classroom teacher will take over for the all important"follow-up"period.The students will ask any troublesome questions,and difficult points will be cleared up through discussion.
The teacher in the classroom will have additional electronic tools.On the teacher's desk,the traditional chalk and erasers will have been replaced by a multiple-control panel and magnetic tape players.The tape machines will run pre-recorded lessons which pupils will follow by headphones. The lessons will be specifically geared to the students' levels of ability.For instance,while the class as a whole studies history,each student will receive an individual history lesson,directed to his par-ticular level of ability.
Should question arise,the students will be able to talk directly to the teacher on individual intercoms without disturbing the rest of the class.In this way,the teacher will be able to conduct as many as three classes at the same time.
With the rapid development of computer science,students will be aided with specially prepared multi-media software to study their subjects better. Homework will possibly be assigned and handed in via electronic mail system. Students can even take examinations on their computer linked with the teachers' and get the score instantly.They will get certificates or diplomas if they pass all the required examinations.Experts believe that this type of education will be very popular in the years ahead.
When having lessons,the students will_________.
A.always listen to the same pre-recorded lessons together
B.usually have individual lessons according to their ability levels
C.control the multiple-control panel and magnetic tape players
D.receive face-to-face instructions from the teacher in the same classroom
