How fit are your teeth? Are you lazy about brushing them? Never fear: An inventor is on the case. An electric toothbrush senses how long and how well you brush, and it lets you track your performance on your phone. The Kolibree toothbrush was exhibited at the International Consumer Electronics Show in Las Vegas this week. It senses how it is moved and can send the information to an Android phone or iPhone via a Bluetooth wireless connection. The toothbrush will be able to teach you to brush right (don’ t forget the insides of the teeth!) and make sure you’ re brushing long enough. “It’ s kind of like having a dentist actually watch your brushing on a day-to-day basis, “ says Thomas Serval, the French inventor. The toothbrush will also be able to talk to other applications on your phone, so developers could, for instance, create a game controlled by your toothbrush. You could score points for beating monsters among your teeth. “We try to make it smart but also fun, “ Several says. Serval says he was inspired by his experience as a father. He would come home from work and ask his kids if they had brushed their teeth. They said “yes“ , but Serval would find their toothbrush heads dry. He decided he needed a brush that really told him how well his children brushed. The company says the Kolibree will go on sale this summer, for $ 99 to $ 199, developing on features. The U. S. is the first target market. Serval says that one day, it’ll be possible to replace the brush on the handle with a brushing unit that also has a camera. The camera can even examine holes in your teeth while you brush.

Imagine a school that expected its students to become literate without any formal instruction. Most parents would be alarmed by such an approach, which would leave their children confused and with gaps in their understanding. This however has been the philosophy on character development in many of our schools. Why is the development of character seen as somehow different from the other skills that we teach? Of course there will always be learning by osmosis (耳濡目染) in any school, but as a teacher and primary school head I have found that a child’ s moral literacy is strengthened when they acquire the building blocks of good character such as consideration, courage and honor: qualities which are commonly known as virtue. I personally find that exploring a virtue over a two-week period provides a simple and effective program that allows for the creative input of both teacher and student and a chance for the virtue to embed itself. Once a lesson on a virtue such as honesty has been completed, we need to allow time for children to practice this concept just as would be the case with fractions or verbs. Allowing children to role play a situation such as making up excuses to cover a mistake can be enormously interesting, and the drama can be frozen allowing the characters to be questioned about their feelings and motives. It’ s also a safe way for children to experience for themselves how a lie usually goes out of control. Our role as educators is also to look for opportunities to help our students as they attempt to strengthen their characters. When something goes wrong we guide the young person to the virtue that will prevent it from happening again. For instance, when a student thoughtlessly disturbs the calm atmosphere of the library, instead of a response such as, “ that was really disrespectful and selfish of you!“ we draw out from them the required virtue: “ When you’ re walking through the library, what virtues do you need to use?“

The theme of the International Literacy Day this year is the connection between literacy and sustainable development. Literacy helps reduce poverty and enables people to find jobs and obtain higher salaries. It is one of the most efficient ways of improving the health of mothers and children, understanding doctors’ prescriptions and gaining access to healthcare. The lives of more than two million children under the age of five were saved between 1990 and 2009 thanks to improvements in the education of women of reproductive age. Literacy facilitates access to knowledge and triggers a process of empowerment and self-esteem that benefits everyone.

Interviewer: How long did you live in the States? Interviewee: I was there for two years, in New York, and I enjoyed it tremendously.

The old idea that child prodigies “burn themselves“ or “overtax their brains“ in the early years, therefore, are prey to failure and (at worst) mental illness is just a myth. As a matter of fact, the outstanding thing that happens to bright children is that they are very likely to grow into bright adults. To find this out, 1, 500 gifted persons were followed up to their thirty-fifth year with these results. On adult intelligence tests, they scored as high as they did as children. They were, as a group, in good health, physically and mentally. Eighty-four percent of their group were married and seemed content with their life. About 70 percent had graduated from colleges, though only 30 percent had graduated with honors. A few had even flunked out (退学) , but nearly half of these had returned to graduate. Of the men, 80 percent were in one of the professions or in business, managers or semi-professional jobs. The women who had remained single had offices, business, or professional occupations. The group had published 90 books and 1, 500 articles in scientific, scholarly, and literary magazines and had collected more than 100 patents. In a material way they didn’ t do badly either. Average income was considerably higher among the gifted people, especially the men, than for the country as a whole, despite their comparative youth when last surveyed. In fact, far from being strange, maladjusted (难以适应) people locked in an ivory tower, most of the gifted were turning their early promises into practical reality.
