浅谈高职英语口语教学

高等职业技术教育中英语专业口语课堂教学不同于以往的口语教学课，因为时代的发展，社会对应用型人才的需求，高职学生的口语课应遵循下列规则：“听”领先于“说”；提高学生的口语交际能力即让他们的表述达意并且得体；注重英语的社会化因素；课堂应以学生为中心，把创造性教育融于职业教育中，教学内容要有时代气息。     

话语分析:如何为媒介社会语言实践提供说明?--兼评《话语与社会变迁》的传播学意义

当代英国语言学家诺曼?费尔克拉夫是西方传播学中批判的话语分析学派的著名代表人。他通过自己的著述和教学活动，为当代媒介等社会语言实践提供了独特的分析视角。本文侧重于他的《话语与社会变迁》的传播学意义的问题，讨论话语分析与媒介话语实践之间的关系。     

高等师范工笔花鸟画教学中的几个问题及对策

目前师范类美术专业的很多学生进校时仅有一点素描和色彩的基础,对民族传统绘画知之甚少,而需要学习的各类文化、专业课程多,在工笔花鸟画课程方面的课时较少。在教学中,学生面对丰富的工笔画形式无法着手学习传统的基础技法、学习基础技法后不知如何结合现当代的美学思想及工笔画发展趋势,拓展思维,培养创作意识。因此指导学生选择临本、熟悉工具材料性能、选择典型题材进行教学、大胆进行新材料、新技法的尝试等,在有限的教学时间内就能提高学生的学习效果。     

媒介集团化的喜悦与尴尬

媒介集团化被认为是我国媒介走向世界的重要措施，但媒介集团化应该是市场经济的产物，还是行政命令的结果，并没有取得共识。违背新闻传播媒介自身发展规律的集团化过程遭遇了预料之外的尴尬。集团化以后的媒介社会性质和社会地位应该怎样确定，如何尽快掌握世界传播市场一体化背景下的媒介集团运行规律、规则和各种惯例，成为媒介集团化能否加速进行的重要问题。     

论加强高职教育中珠算教育的必要性

高等职业技术教育作为高等教育的重要级成部分，在华夏大地迅猛发展，珠算教育在高职教育中至关重要，从培养目标，招生对象，专业设置，职业资格，国情实际，国际经验，科学知识淘汰率及党和国家领导人重视珠算等诸多方面都可以看到加强高职教育中的珠算教育的必要性。     

信息技术与课程整合不等同于CAI

该文从历史发展背景、内涵、目标、教学过程以及对教师和学生的要求等方面对信息技术与课程整合、计算机辅助教学加以区分,并对二者的发展前景做出展望。     

农远工程中信息化教学的“公开课情结”分析及对策研究

"公开课情结"是农远工程中信息化教学挥之不去的一种普遍现象,即信息技术与课程整合仅仅停留在公开课层面,难以持续、深入到常态课中。该文就这一现象进行了剖析,并提出了理性应用合适技术,应用发展性评价,基于校本资源建设以及多因素协同构建良好支持环境的解决对策。     

Hybrid ants-like search algorithms for P2P media streaming distribution in ad hoc networks

Media streaming delivery in wireless ad hoc networks is challenging due to the stringent resource restrictions,po-tential high loss rate and the decentralized architecture. To support long and high-quality streams,one viable approach is that a media stream is partitioned into segments,and then the segments are replicated in a network and served in a peer-to-peer(P2P) fashion. However,the searching strategy for segments is one key problem with the approach. This paper proposes a hybrid ants-like search algorithm(HASA) for P2P media streaming distribution in ad hoc networks. It takes the advantages of random walks and ants-like algorithms for searching in unstructured P2P networks,such as low transmitting latency,less jitter times,and low unnecessary traffic. We quantify the performance of our scheme in terms of response time,jitter times,and network messages for media streaming distribution. Simulation results showed that it can effectively improve the search efficiency for P2P media streaming distribution in ad hoc networks.     

Teachers’ technology adoption and practices: lessons learned from the IWB phenomenon

The twenty-first century has seen unprecedented investment from governments around the world in educational technologies in schools. This paper investigates Australian teachers’ adoption and use of a popular technology that has been extensively supported by governments and school systems: the interactive whiteboard (IWB). The study suggests that a number of the barriers identified in the early days of adoption and use of this technology, such as professional support and access, still remain for many teachers, thereby impeding effective practices. The research also found that primary school teachers were using the technology in diverse ways, in contrast to secondary teachers who were using the IWB mainly for instructionist, presentational purposes. We conclude by considering various ways of reducing the effect of the identified barriers to support implementation of educational technologies in the classroom, especially the next generation of technologies promoted by governments and systems.
