谈航海职业院校英语师资队伍的建设

国际贸易、世界海运业的发展对从事航海职业技术教育院校的英语师资提出了新的要求与挑战,但目前航海职业技术院校航海英语教师比例偏低与结构不合理的现状,已经严重制约了我国高等航海职业技术教育教学质量,阻碍了我国海员向国际海员劳务市场进军的步伐。为此,笔者提出了自主培养为主、人才引进为辅、加强国际人才交流、完善配备设施等建设航海职业院校英语师资队伍的方法与途径,以满足航海英语教育教学的需要。     

The Virtual Learning Environment ROODA: An Institutional Project of Long Distance Education

This article describes ROODA (), a virtual learning environment and one of the official Long Distance Education platforms that has been in use since 2005 at the Federal University of Rio Grande do Sul (UFRGS), Porto Alegre, Brazil. It is free software that integrates syncronous and assyncronous interaction/communication tools and publications. In this study, details about institutional demands in relation to long distance education are discussed and ROODA is described with the components that were part of its development such as: modelling and programming, graphic interface and documents for users. Moreover, 19 functions were conceived. Finally, project investigation paths are presented where the platform described is inserted.

世代特征，信息环境变迁与大学生信息素养教育创新

当前世代大学生偏好的教育活动是个性化服务,电子媒介交互式学习,任务参与型学习甚至自主的学习;他们具备一定的信息素养能力,但差异巨大。本文指出:随着Internet技术及应用的深入发展,大学生信息素养能力包括三个层次,低层次是信息检索技能,然后是批判性思维能力和与自己专业密切相关的IT能力,更高层次是独立思考、认识论认知能力,最终达到解决实际问题的目的;高校图书馆已经不能独立满足学生多层次信息素养能力的要求及当前世代大学生对教育培训的偏好。本文提出信息素养教育五分策略:培养目标分层,教学内容分级,学科专业分类,培养过程分段,学生管理分流,并建议从网络课堂、图书馆、学院、学校、教育部、第三方平台等多个层面,共同推动我国大学生信息素养教育。图3。表3。参考文献63。     

完善我国海洋资源政策的思考

海洋资源的合理开发利用是我国社会经济发展的重要保证.目前我国海洋资源政策存在不少问题:政策的政出多门容易损害渔民利益;政策单项居多导致海洋资源的综合优势不能发挥;政策制定目标偏差导致海洋资源受损;政策执行不力影响渔业的可持续性发展.针对上述问题提出几项改善对策:设立中央级别的海洋政策机构;加快制定综合性的海洋资源政策;加强以生态理念为导向的政策目标;加强海洋资源政策执行的监督与评估.     

Mapping beliefs about teaching to patterns of instruction within science,technology, engineering,and mathematics

In this paper, we identify beliefs about teaching and patterns of instruction valued and emphasized by science, technology, engineering, and mathematics faculty in higher education in the USA. Drawing on the notion that effective teaching is student-centered rather than teacher-centered and must include a balance of knowledge-, learner-, community-, and assessment-centered learning environments; we use qualitative interview data to explore how faculty's reported beliefs about teaching are associated with their consideration of these four types of environments. Findings indicated that although a range of beliefs about teaching emerged, most were firmly located in knowledge-centered learning environments, with little or no focus on the remaining three learning environments. Furthermore, even patterns of instruction that were heavily student-centered were situated within a knowledge-centered learning framework. We argue that for student-centered instruction to be truly successful, faculty must consider all four learning environments in crafting and facilitating the classroom environment.

The role of model building in problem solving and conceptual change

This study examines the effects of the activity of building systems models for school-based problems on problem solving and on conceptual change in elementary science classes. During a unit on the water cycle in an Asian elementary school, students constructed systems models of the water cycle. We found that representing ill-structured problems as system models improves problem solving as well as creating beneficial conceptual change related to the topic.     

The Promise of Ecological Inquiry in Writing Research

Ecological inquiry (EI) in research of academic and workplace writing explores interactions between individuals and environments as these entities interpenetrate. This article provides a brief history from the past 3 decades of developments in writing theory. It then outlines the key tenets of EI, highlights how EI is compatible with other models, and presents new and interesting possibilities afforded by this type of inquiry.     

Characterizing navigation in interactive learning environments

Interactive learning environments (ILEs) are increasingly used to support and enhance instruction and learning experiences. ILEs maintain and display information, allowing learners to interact with this information. One important method of interacting with information is navigation. Often, learners are required to navigate through the information space of an ILE, a process which can be quite difficult and cognitively exacting as the information space becomes very large and complex. Proper design can make this process less exacting and, at the same time, facilitate better learning of the information space. However, this is not easy to do, especially for ILEs. Frameworks can assist in the effective analysis and design of interactive environments. However, there is lack of conceptual frameworks for guiding the analysis and design of navigation in ILEs. This paper tries to address this issue by presenting a framework which can be used to characterize navigation within ILEs. To create this framework, this paper brings together research from various disciplines, such as human-computer interaction design, educational multimedia design, cognitive technologies and learning sciences. This framework prescribes a three-stage process for designing and analyzing navigation: 1. content structuring; 2. information navigation modeling; 3. interface presentation structuring. By bringing these three stages together, it is intended to provide a conceptual framework to assist and guide designers in the proper analysis and design of navigation in ILEs.
