关于IPV6对泛在学习支持的探索研究

以IPV6网络协议为基础的网络技术是下一代信息技术的核心,它以其先进性能够解决目前网络上所存在的许多问题,克服许多的弊端。未来的泛在学习只有在一个充满信息和通信的环境下才能实现,而IPV6则是实现这一进程的有力支持,它为泛在学习的实现提供了很大的可能。     

大鼠运动后不同时相血浆IL-6变化的比较

取股动脉血检测,并对比目鱼肌做电镜和光镜的观察.结果:(1)大鼠运动后骨骼肌纤维结构发生明显改变,其变化以运动后24小时较为显著.(2)大鼠运动后血浆IL-6水平较运动前出现显著增高,且在运动后48h出现峰值.(3)运动后血清LDH活性较运动前显著增高,出现先升后降,且峰值出现在运动后即刻.运动后血清Ca2 水平较运动前显著降低.结论:(1)运动后超微结构的损伤明显,且损伤较严重的时相出现在运动后24h左右,可能是离心运动致机械损伤和运动强度及持续时间共同作用的结果.(2)大鼠血清IL-6水平在运动后显著增高,结合电镜和光镜结果,表明IL-6与运动性骨骼肌损伤有重要关联性可作为运动性骨骼肌损伤检测的一个重要指标.

The keyword method compared to alternative vocabulary-learning strategies

Imagery and sentence versions of the keyword method of vocabulary learning were contrasted with three nonkeyword verbal-contextual alternatives. Subjects' definition learning in the imagery keyword condition was substantially higher than when subjects were presented the vocabulary in sentence contexts, when they generated sentence contexts for the words, when they made decisions about whether the words were used correctly in sentences, or when they were left to their own devices to learn the words. The learning benefits associated with the sentence keyword version were not as dramatic as in the imagery keyword condition. They were more evident when recall of any part of the definition was considered correct than when recall of the entire definition was necessary. These results indicate that the keyword method is a potent alternative to vocabulary-learning techniques that are regarded as effective by curriculum experts in reading.     

The stage-learning hypothesis: Strategies for instructional design

According to the stage-learning hypothesis, children's ability to learn various concepts is constrained by their pretraining stages of cognitive development. Although this hypothesis has important instructional and theoretical implications, little progress has been made on obtaining unconfounded tests of the hypothesis. Some procedures for obtaining such tests are developed in this paper, and some applications to factorial experiments are considered.
