Education is intimately associated with communication, and so may utilize any technology that is able to support a process that enables information to be transferred from one location to another. This paper describes the meaning of the term multi-media data base and presents a model of its potential role in aiding message creation for the purposes of communicating educational material using many parallel channels. Some of the problems associated with the implementation of such systems are outlined. 相似文献

John G. Paterson Carl A. Blashko 《International journal for the advancement of counseling》1985,8(1):25-30
The authors are co-hosts of a popular open line radio show in Western Canada. In this article the term media counseling is explored and strategies in bringing expertise from the fields of Psychology and Psychiatry to the public are outlined. The authors have been convinced of the value of their approach, and outline purposes, as well as providing data relevant to this radio show That's Living. 相似文献

A cowse‐integrated programme of library instruction has been developed for the School of Civil Engineering at the Queensland University of Technology, Australia; library instruction being one of the means selected to improve the research efforts of fourth year project students. The programme has been developed through consultation between the Civil Engineering Research Project Coordinator and the Civil Engineering Reference Librarian. Its aims are derived from those established for the fourth year research projects. Attention is focussed on the nature of the programme and the impact of instruction on fourth year research project students. Students who had received extended library instruction were compared with students from the previous year. Evidence suggests that the instruction has improved the information seeking behaviour of the students and their literature reviews. 相似文献

The success of an intervention depends not only upon its theoretical soundness, but also on proper implementation that reflects
the guidelines derived from its theoretical conception. Debates surrounding the effectiveness of problem-based learning (PBL)
have focused on its theoretical conception and students’ learning outcomes, but implementation is seemingly absent from the
picture. This paper attempts to describe what research evidence is needed to fill in this missing information and provide
a clearer picture of PBL. The author examines current PBL implementation practices and identifies potentially confounding
variables that may play a role in inconsistent or conflicting research results in PBL. For example, various models of PBL
have been developed and implemented to afford the specific instructional needs of the institution or learner population. These
PBL models are in fact quite different in terms of the nature of problem solving and the degrees of self-directed learning,
which theoretically, should result in different types of learning outcomes. Without distinguishing the models used, the results
of comparative PBL research could have been confounded. Furthermore, human factors are another set of confounding variables
that could influence the students’ learning processes and consequently affect PBL implementations and research results. To
remedy these problems and reach PBL’s full potential, as well as obtain a more accurate picture of PBL as an instructional
method and its effects on students’ learning, some fundamental changes are needed. 相似文献

This study employed a qualitative research design to investigate how instructional designers use evaluation in everyday design
practice. While past research has examined how designers spend their time, how they generally make decisions, and expert-novice
differences, little attention has been paid to use of context, input, process, or product evaluation, from the perspective
of practicing designers. Based on interviews of practitioners, our findings included ten themes regarding how designers use
evaluation to improve their products. While these results substantiate to some degree the claim that practitioners believe
clients will not pay for formal evaluations, they also suggest that practitioners use evaluation in important but less formal
ways. Other conclusions regarding the role of evaluation in design are provided and future directions for training and research
are discussed. 相似文献

Radio is migrating to digital transmission, expanding its offerings to include captioning for individuals with hearing loss. Text display radio requires a large amount of word throughput with minimal screen display area, making good user interface design crucial to its success. In two experiments, we presented hearing, hard-of-hearing, and deaf consumers with National Public Radio stories converted to text and examined their preferences for and reactions to midsized and small radio text displays. We focused on physical display attributes such as text color, font style, line length, and scrolling type as well as emergency alert messages and emergency prompts for drivers, announcer identification schemes, and synchronization of audio and text. Results suggest that midsized, Global Positioning System (GPS)-style displays were well liked, synchronization of audio and text was important to comprehension and retrieval of story details, identification of announcers was served best with a combination of name change in parenthesis and color change, and a mixture of color and flashing symbols was preferred for emergency alerting. 相似文献

Akindele Matthew Ige 《Early Childhood Education Journal》2011,39(2):161-167
Early childhood is a critical period of rapid physical, cognitive, and psycho-social development of a child. The quality of
care and education which a child receives at this crucial age will determine to a great extent the level of his/her physical
and cognitive development in the future. In Nigeria, Early Childhood Care, Development and Education (ECCDE) is an aspect
of Universal Basic Education which was introduced in 1999 to increase the access of children to basic education and improve
the state of education in the country. While all hands are on deck to ensure successful implementation and achievement of
the objectives of the scheme, it is unfortunate that ECCDE is facing some challenges thus making it unrecognized in Nigeria.
This paper examines the challenges of early childhood education in Nigeria. To improve the situation, the following measures
are recommended: establishment of more public crèche, kindergarten, and nursery schools by the government; enforcement of
the use of mother tongue in the teaching of children; training more personnel in the field of early childhood education in
tertiary institutions; and introducing unified curriculum as well as providing more infrastructures. 相似文献

Lynne Cherry Brandwein Lecture March 2010 National Science Teachers Association (NSTA) Conference, Philadelphia, PA. Young
Voices on Climate Change: Inspired and Empowered Youth Tackle Climate Science and Find Climate Solutions. As a child, Lynne
Cherry was profoundly connected to the natural world and a special place. She watched the destruction of her world. Now, through
her Young Voices on Climate Change project, she is trying to give teachers and young people the tools to prevent planetary
meltdown on a greater scale. Global climate change is upon us and the need for education and action is immediate. Outreach,
visual storytelling, and scientific understanding are especially necessary in light of the recent polls that show that the
public is becoming more confused and less concerned about climate change. Cherry’s climate book, co-authored with photojournalist
Gary Braasch, and her Young Voices on Climate Change films feature climate solutions. They’re about win–win—save the environment,
protect human health, reduce global warming gases, demonstrate youth making a difference with practical tools, motivate engagement
in climate science, take pride in increased science literacy, reach young people through their hearts as well as their minds,
and save money. Although young people can help their parents, peers and communities understand climate science, they can also
show them that reducing CO2 is in their economic interest, and spur them to take action. School carbon reduction initiatives are spilling over into communities
yielding measurable results in both global warming gas reductions and significant monetary savings. 相似文献
