Film scenes in interdisciplinary education: teaching the Internet of Things*

The Internet of Things (IoT) is gaining importance in education owing to its rapid development. This study addresses the importance of interdisciplinary education between technology and the humanities. The use of films as a teaching resource is suitable for interdisciplinary education because films represent creative forecasts and predictions on future human society, helping the public realize what could occur in the future. By utilizing films in instruction, students can be trained to understand the three key functions of IoT and acquire the ability to develop creative applications of IoT. An IoT teaching model using the films Minority Report (2002), Big Hero 6 (2014), Iron Man 3 (2013), Her (2013), and Transcendence (2014), all of which depict various applications of IoT that could be helpful in the teaching of the functions and concepts of IoT, is suggested; an interdisciplinary class is carried out for 15 weeks following the model. The effectiveness of the class is measured using quantitative analysis, qualitative analysis, and reflection journals. The findings show that students developed interdisciplinary capacity through education using films.

Convergence in education policy? A quantitative analysis of policy change and stability in OECD countries

In this article, we quantitatively assess education policy change in OECD countries. While research has frequently underlined the importance of international exchange for national policy development, it is yet unclear whether resulting policies are converging. By distinguishing different kinds of education policy goals, we hypothesise that indicators related to macro-level goals are more likely to converge than those related to implementation. We then analyse the development of several education policies since the 1990s. We find strong convergence of some indicators and among some groups of countries, but no clear pattern emerges. Convergence is only partially influenced by the abstractness of education policy goals, and in particular the Scandinavian countries seem to pursue their own approaches in important education policy options.     

网络融合对普通高校体育选项课微格教学的影响分析与对策

中国努力推动的"三网融合"让此前竖立在计算机网、广播电视网和电信业务网之前的藩篱逐步撤除,将引发微格教学模式的深远变革。本文就其相关问题进行分析,从技术革新的视角探讨体育微格教学的应用模式,提出一个基于终端设备小型化的体育选项课微格教学系统设计思路,利用三大网络素材库,引进非线性视频编制、多维动画及网络3D互动等新技术,采用网络群组式教学等对策,以期发挥小型化课堂优势,增强体育微格教学的实效性。     

关于牛顿迭代公式的改进

经典的牛顿迭代公式是求解非线性方程的一个基本方法,它在单根具有平方收敛,在重根处只具有线性收敛,这里给出解非线性方程的牛顿迭代公式的一种改进,使得牛顿迭代公式在重根处也具有二阶收敛速度.

体育强国背景下体育产业融合研究

体育产业产值占据国民经济的比重越来越大、新型业态层出不穷,结合产业演进发展规律研究体育产业融合路径对于新时代发展体育产业经济构建体育强国具有重要意义。目前研究多是从体育产业发展现状和产业演进客观规律角度研究体育产业融合路径,缺乏对时代性体育强国政治和经济诉求分析。采用文献资料法和统计分析法,分析新时代体育产业融合动因,整理归纳体育产业融合的时代性、必要性,结合产业演进客观规律总结体育产业融合路径。研究表明：我国体育产业是基于体育强国政策导向、体育消费需求升级和产业发展规律下融合的,融合策略是技术融合、功能复合式融合、资源有效整合三种方式。
