一类随机时滞抛物型模糊细胞神经网络的指数学习同步

探讨一类随机时滞抛物型模糊细胞神经网络的指数同步控制问题。利用Lyapunov–Krasovskii–like复合能量函数和自适应学习控制方法,建立了两个具有随机扰动的混沌时滞抛物型模糊细胞神经网络的指数同步控制的判据,这些结果容易检验且依赖于空间测度,与先前结果相比具有较少保守性。最后,通过仿真实验验证了所得结果的有效性。

An Investigation of English Language Learning in Synchronous （SL） and Asynchronous （ASL） E-Learning

This study investigated the factors affecting the English language learning of students in SL （synchronous） and ASL （asynchronous） e-learning. The subjects were 102 undergraduate students at Bang Khen and Kamphaengsaen Campus, Kasetsart University. Before the experiment, the subjects answered an online questionnaire adopted from Reid （1998） to measure their perceptual learning style preferences. Then, they were grouped according to their English grades and were randomly assigned to two experimental groups. Each group was given learning tasks requiring different cognitive strategies. The two groups received two treatments with SL and ASL simultaneously. After each treatment, both groups were tested. They were given a questionnaire at the end of the treatments to retrieve their opinions, Data from both tests were analyzed using 2 ~ 2 factorial ANOVA repeated measures. The results showed no significant difference between the two tasks and no interaction effect among types of tasks and SL and ASL. However, a significant difference was found between SL and ASL. The results of the survey showed that the subjects preferred ASL which was in contrast to the results from statistical analyses. The learning style preferences of the two experiment groups were not different; therefore, they were not the factors in the analysis

学本视角下同步课堂教学的困境与对策

随着网络技术的发展,异地学校同步课堂在优质资源共享、促进区域教育均衡方面取得了一定成效。然而,当前同步课堂的教本属性制约了其效能的发挥。结合教学实践的成效考察,从学本视角出发对同步课堂的剖析发现,教与学的割裂、学情的差异、内容的传输受限、教学交互的离身四个因素导致了难以同步的课堂现状,增强同步课堂效能需要以学定教,弥合学情鸿沟;先学后教,提高课堂效能;适性互动,调节课堂氛围;具身设计,提升学习体验等策略。
