Materials handling is a vital function in a manufacturing or distribution system. Efficient handling of material allows such systems to operate at high levels of productivity. US companies invest over US$60 billion annually in materials handling technology. It is therefore extremely important for universities to prepare materials handling engineers who understand the principles of materials handling, as well as the design, implementation, operation and control of materials handling systems so that they can ensure the cost-effectiveness of this investment. This paper pertains to development of an interactive, multimedia-based system for use in materials handling classes. Modules in the system introduce students to: the 10 principles of materials handling; and two major equipment categories—conveyors and automated storage and retrieval systems. They illustrate industrial applications of material handling equipment and teach the problem-solving process through a case study and an extensive series of models, algorithms, problems and solutions. The modules have been formally evaluated and results are summarized. They are being distributed at a nominal cost to US and international universities. The module described in this paper on the ‘10 principles of materials handling’ was selected as a finalist for the 2002 PREMIER Award for Excellence in Engineering Education Courseware. 相似文献

Students from three different British Columbia grade six classes were followed through two weeks of instruction on climate change. Pre, post, and follow-up surveys were used to determine the differences in knowledge gained and retained by students that received direct instruction from their science teacher, and by those who received equivalent content instruction from outside presenters. The teacher participant also completed a survey on her experience with the researcher-designed lesson plans. Students’ results on the surveys were compared to results from a control group with no intervention. The teacher-based setting resulted in significantly higher knowledge gain, although no difference was found between the groups’ rate of knowledge decline thereafter. Highest gains in knowledge were for the carbon cycle and the human impacts topic, followed by understanding the difference between climate and weather. The students and teacher alike appeared to struggle with the topic of global warming and the greenhouse effect. The research suggests that with the appropriate background information the classroom teacher is likely to be more effective at conveying the science of climate change, particularly when it is taught through an understanding of the carbon cycle and its human impacts. It also suggests that those non-governmental organizations engaged in climate change education might be better served by investing their limited resources in the development of learning materials and subsequent professional development for teachers rather than focusing on in-school presentations. 相似文献

Basal reading manuals have been found to be utilized with gifted readers (Cagney &; Sakiey, 1984). Therefore, this study attempted to determine if the eight components delineated to be more important to gifted than nongifted readers by reading and gifted educators in the Dole and Adams (1983) study were included in basal materials. Three basal series were examined and it was found that seven of the eight components were included, mainly in the enrichment section of the manual. Therefore, basal manuals can meet the needs of gifted readers if utilized appropriately. 相似文献
