It's every parent's worst nightmare.
Dr Gary Smith, a co－author of the research from the Nationwide Children's hospital in Ohio and his colleagues report how they compared the effects of four different smoke alarms on 176 children aged between 5 and 12 years old.

【推荐3】Being social and emotional from an early age is likely to help children win acceptance by their peers, build better relationships with teachers, and facilitate academic learning. According to research, pretend play is a teaching tool that can be used to stimulate a child's all-round development.
A curriculum based on this approach has been introduced in classes of pupils aged five and six by a research team from the University of Geneva. The study shows that pupils who followed the curriculum increased their emotional recognition capacities and emotional level compared to a control group. The use of pretend play as a teaching tool enables children to acquire emotional skills, with a potential positive effect on their prosocial (亲社会的) behavior and, in the longer term, on their academic success.
“Potential leads for learning do exist,” says Sylvie Richard. “We know already that pretend play promotes the understanding and regulation of emotions together with prosocial behavior in the early stages of schooling.”
Pretend play gives children the opportunity to use their imagination, in particular by means of scenarios (剧本) that they invent and the roles they play. “For instance, they can pretend to be a wizard or a witch who's making a kind of magic water that will send a dangerous dragon to sleep. The child creates the rules, adjusts them to suit their situation, and calls on their imagination,” explains Sylvie Richard.
A total of 79 children took part in the research, with the result showing an improvement in the recognition of emotions, particularly anger. The children also build up their emotional vocabulary. "The results suggest, on the one hand, that it's essential to design a teaching system that takes pretend play into account as areas of knowledge that should be taught. On the other hand, the study shows that using this kind of play helps children experiment," concludes Sylvie Richard. Given its success, the study is continuing with a more extensive curriculum, which is being carried out now in Valais.
