In the project Technology in Secondary Education: Problem-solving in Teaching/learning Packages, two experiments regarding a construction problem and an explanation problem were conducted, in which two variants of a teching/learning package (strongly structuredvs. weakly structured) were compared. Only with the strongly structured instructional variant of the package for the explanation problem did the pupils come to a quick solution of the problem. In both experiments, the factors that influenced the problem-solving processes of the pupils were investigated. The results are of importance for curriculum developers and the authors of teaching/learning packages for Technology but further research into the factors influencing the problem solving process of pupils is necessary. 相似文献

The Effects of Megamergers on Efficiency and Prices: Evidence from a Bank Profit Function 总被引:4,自引:0,他引:4
Akhavein JALAL D. Berger Allen N. Humphrey David B. 《Review of Industrial Organization》1997,12(1):95-139
This paper examines the efficiency and price effects of mergers by applying a frontier profit function to data on bank megamergers. We find that merged banks experience a statistically significant 16 percentage point average increase in profit efficiency rank relative to other large banks. Most of the improvement is from increasing revenues, including a shift in outputs from securities to loans, a higher-valued product. Improvements were greatest for the banks with the lowest efficiencies prior to merging, who therefore had the greatest capacity for improvement. By comparison, the effects on profits from merger-related changes in prices were found to be very small. 相似文献

Decisions regarding health care practices and technology are never static. As new information becomes available, and internal and external forces shift, new decisions may have to be made. Such is the decision regarding reusable versus disposable linen. Until very recently, reusable linens were not comparable with disposable linen in the quality characteristics that directly impact patient and staff safety and health. Given the current test results on the latest generation of reusable fabrics, it is time to go back to reconsider this decision for the future. 相似文献

If it is accepted that both the system and the individual can act as barriers to development at the micro‐level, development policy could be aimed at identifying the major causes and sources of inefficiency and removing the existing barriers to the achievement of efficiency.
In this article the major barriers to system efficiency are identified as being physical and institutional, and they include the physical structure of irrigation schemes, the land tenure system and the marketing structure. A theoretical discussion of each of these factors is used to propose more specific strategies for micro‐level rural development. 相似文献
