试述建构主义关于学习与教学的基本思想及其对当前教育实践的启示。
(1)基本观点:建构主义者提出了建构主义的知识观、学习观和学生观。在知识观上强调知识的动态性;在学习观上强调学习的主动建构性、社会互动性和情境性;在学生观上强调学习者本身已有的经验结构。
(2)对当前教育实践的启示:①从建构主义的知识观出发,建构主义强调知识是个体对于现实的理解和假设,其受到特定经验和文化等的影响,因此每个人对知识所建构的理解都是不同的。教师在教育教学过程中应当要更加重视学生的个性化特点,因材施教。②从教学的角度来看,建构主义认为学习就是主体对学习客体的主动探索、不断变革,从而建构对客体意义理解的过程。因此,在教学中应当注意学生的有意义建构,通过适当的教学策略启发学生能够自主建构认知结构。③从学习者的角度出发,建构主义认为学生是意义的主动建构者,而不是外部刺激的被动接受者和被灌输的对象,因此,在教学过程中除了传统知识的传授,还应当充分发挥学生的主体地位,强调学生的自主性和能动性,在学习过程中能够主动发现、分析、解决问题。

For the futurist
The T-Mobile G1 is very popular as it is thefirst phone to offer a Google browser, meaning that you′re getting the real webon your phone, but it′s the phone′s potential that qualifies it for the futurist.The exciting applications are interesting, but they don′t always work smoothly.Sometimes it is hard to use the applications it comes with. The system shouldimprove as it becomes more popular, so it holds great promise. With fewrestrictions on the design of applications for the phone,
the G1 could be the first phone toincorporate (整合) some of the coolest.
For the road warrior
The new BlackBerry Storm is something likethe equivalent (等同物) of a mullet--a business up front, party in the back. It stillincorporates the serious mail and organization features that have endeared (使受钟爱) these phones to business people. The 3.25-inch is bright anddetailed and it′s a decent size for watching videos on the go.
For the Luddite (反对技术进步的人)
