Research into Practice: Current Trends in Educational Technology Research: The Study of Learning Environments

Educational technology research has passed through a number of stages, focusing, in turn, on the content to be learned, the format of instructional messages, and the interaction between computers and students. The field is now concerned with the study of learning in complete, complex, and interactive learning environments. These environments allow both the simulation of experiences that students might have in the real world and also the creation of compelling experiences that cannot normally be experienced directly. Learning environments also often allow students to communicate their own ideas with the use of a variety of symbol systems. These environments are also frequently inhabited by more than one person, making learning within them a social activity where learning is distributed among both people and artifacts. Finally, these learning environments are complex. Studying how they contribute to learning therefore requires research methods other than controlled experiments. This paper reviews research on learning environments to give both an historical perspective on educational technology research and a selective view of the current state of the discipline. It concludes by identifying implications for both practice and future research.     

远程教育的时间观--从人类学的观点看

通过梳理时间概念的历史,以及借鉴教育人类学对时间问题的研究成果,可以得出这样的结论：远程教育利用其媒体技术创造了一种可以称作为“虚时间”的新的时间形态,这使得远程教育在克服时间距离方面出现了可能,但同时也在师生沟通方面增加了其他难度,     

Developing a virtual engineering management community

The paper reviews the lessons of planning and running an Engineering Management practitioner development programme in a partnership between BP and the University of Manchester. This distance-learning programme is for professional engineers in mid-career experienced in the engineering and support activities for delivering safe, compliant and reliable projects and operations worldwide. The programme concentrates on the why and how of leadership and judgement in managing the engineering of large and small projects and operational support. Two intensive residential weeks are combined with a virtual learning environment over one year. Assessed assignments between and after the residential weeks provide opportunities for individual reflective learning for each delegate through applying concepts and the lessons of case studies to their experience, current challenges and expected responsibilities. This successful partnership between a major global company and a university rich in research and teaching required a significant dedication of intellectual and leadership effort by all concerned. The rewards for both parties and most importantly for the engineers themselves are extensive.

基于虚拟现实技术的企业认知实践教学设计与仿真实验开发

机械类专业学生企业认知学习的目标和任务是使学生了解企业生产和工作环境,增加学生对机械专业工作岗位群的感性认识,并通过理论联系实际初步培养学生的工程意识、工程素质和工程实践能力,为今后进一步学好各门专业课奠定基础。而由于实习学生人数多、学生实习既耽误工作又妨碍生产,因此很多企业都不太愿意接收学生在企业实习,实习企业难找是目前大部分机械类专业面临的共性问题。本论文针对实习企业难找的问题,利用虚拟现实技术设计了以真实存在企业环境为基础的虚拟认知实践教学环境,并开发了可完成仿真实验的数字化虚拟工厂。基于虚拟现实技术的数字化工厂有效解决了学生实习企业难找的问题,为实习学生提供了不到工厂也能参观企业的各个部门及生产车间、了解生产流程、熟悉各类生产设备和工艺的平台。     

Entering the occupational category of ‘Farmer’: new pathways through professional agricultural education in Ireland

Purpose: Understand the emergence of new potential career trajectories in the liberalised Irish dairy farming sector through analysis of the narratives of students of a Professional Diploma in Dairy Farm Management

Design/methodology/approach: A review of the literature highlights that entry to a working life in agriculture has been characterised by protracted farm succession processes; a strong association between being a farmer and owning land in the family name; lingering male identities esteeming manual labour; and a pragmatic need at farm level for manual work. The abolition of milk quota in 2015 was predicted to catalyse expansion of production on dairy farms with an increase in milk production; accompanied by a demand for qualified personnel. The BNIM method was employed.

Findings: Results confirm that agricultural education is perceived and experienced as offering new pathways for young farmers to enter the occupational category of ‘farmer’, helping to manoeuvre around the constraints of non-inheritance. The students’ narratives evidenced managerial identities, being strongly influenced by encountering management approaches through their agricultural education. All students desired to eventually own a farm someday and to be to employed as a professional dairy farm manager was a perceived as an intermediary goal.

Practical implication: Discontinuation of the traditional family farming model based on family farm/land ownership is not imminent even among a cohort qualified to become employed dairy farm managers.

Theoretical implication: This paper contributes to theoretical framework which highlights the shift in farmer masculine identity and the career trajectory of graduates of specialised agricultural education programmes.
