Cambridge Schools Conference 2015 - book your place today
Inspiring teachers, inspiring learners: How we prepare learners for a lifetime of learning.
Dear Colleague
The Cambridge Schools Conference is taking place in Colombo, Sri Lanka from 3-5 Jan 2015. Booking for the conference closes on 24December 2014, book now to secure your place.
Feedback from schools that attended our recent conference in Cambridge includes:
“Outstanding keynote presentation by Guy Claxton”
Roland Ebiye-Koripamo, Cita International School
“A Cambridge Conference shoots up the expectation level of the representativesand when it not just reaches that level but surpasses it with excellence, you define it as the Cambridge Schools Conference, 2015!”
SeemaAnis, Al Waha International School, Jeddah
“I have met so many interesting people. Having the opportunity to meet educators from all over the world is a unique experience.”
Luciana Fernandez, ESSARP, ArgentinaThe conference brings together a community of teachers representing schools from many different countries and contexts, to consider approaches to common challenges. Our programme is designed to support professional learning by offering a range of perspectives on the conference theme. Discuss and debate these in our panel sessions (小组会议) and explore their implications in group discussions and workshops.
We look forward to welcoming you to Colombo.

Big trees are incredibly important ecologically. For a start, they provide food for countless other species and shelter for many animals. With their tall branches in the sun, they capture vast amounts of energy. This allows them to produce massive crops of fruit and flowers that sustain much of the animal life in the forest.
Only a small number of tree species have the genetic abilityto grow really big. The biggest are native to North America, but big trees grow all over the globe, from the tropics to the forests of the high latitudes(纬度). To achieve giant size, a tree needs three things: the right place to establish its seedling, good growing conditions and lots of time with low adult death rate. Lose any of these, and you will lose your biggest trees.
In some parts of the world, populations of big trees are dwindling because their seedlings cannot survive. In southern India, for instance, an aggressive non-native bush, Lantana camara, is invading the floor of many forests. Lantana grows so thickly that young trees often fail to take root. With no young trees to replace them, it is only a matter of time before most of the big trees disappear.
Without the right growing conditions, trees cannot get really bigand there is some evidence to suggest tree growth could slow in a warmer world, particularly in environments that are already warm. Having worked for decades at La Selva Biological Station in Puerto Viejo de Sarapiqui, Costa Rica, David and Deborah Clark and colleagues have shown that tree growth there declines markedly in warmer years. “During the day, their growth shuts down when it gets too warm, and at night they consume more energy because theirmetabolic(新陈代谢的) rate increases,” explains David Clark. With less energy produced in warmer years and more being consumed just to survive, there is even less energy available for growth.
The Clarks’ theory, if correct, means tropical forests would shrink over time.The largest, oldest trees would progressively die off and tend not to be replaced. According to the Clarks, this might cause a destabilization of the climate; as older trees die, forests would release some of their stored carbon into the atmosphere, causing a cycle of further warming, forest shrinkage and carbon emissions.
Besides, big trees face threats from elsewhere.
