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 On the teacher’s desk, the traditional chalk and erasers will have been replaced by a multiple-control panel and magnetic tape player. The tape machines will run pre-recorded lessons which pupils will follow by headphones. The lessons will be specifically geared to
A. The school with a central building.
B. The school with four or five master studios.
C. The school with television.
D. The school with televised lessons and electronic teaching tools.

In a new study about the way kids learn math in elementary school, the psychologists at the University of Chicago Sian Beilock and Susan Levine found a surprising relationship between what female teachers think and what female students learn: If a female teacher is uncomfortable with her own math skills, then her female students are more likely to believe that boys are better than girls at math.
"If these girls keep getting math-anxious female teachers in later grades, it may create a snowball effect on their math achievement, " said Levine. In other words, girls may end up learning math anxiety from their teachers. The study suggests that if these girls grow up believing that boys are better at math than girls are, then these girls may not do as well as they would have if they were more confident.
