Size and scale cognition is a critical ability associated with reasoning with concepts in different disciplines of science, technology, engineering, and mathematics. As such, researchers and educators have identified the need for young learners and their educators to become scale-literate. Informed by developmental psychology literature and recent findings in nanoscale science and engineering education, we propose an integrated knowledge framework for characterizing and scaffolding size and scale cognition called the FS2C framework. Five ad hoc assessment tasks were designed informed by the FS2C framework with the goal of identifying participants' understandings of size and scale. Findings identified participants' difficulties to discern different sizes of microscale and nanoscale objects and a low level of sophistication on identifying scale worlds among participants. Results also identified that as bigger the difference between the sizes of the objects is, the more difficult was for participants to identify how many times an object is bigger or smaller than another one. Similarly, participants showed difficulties to estimate approximate sizes of sub-macroscopic objects as well as a difficulty for participants to estimate the size of very large objects. Participants' accurate location of objects on a logarithmic scale was also challenging.  相似文献

Training Alone Is Not Enough

Improving healthcare services in the developing world remains a major goal for many organizations and despite enormous training and program investments from international organizations, service improvements have been modest. This study looks at how to improve results by examining the relationship between the conditions in a healthcare providers' work environment and his or her performance. Drawing upon a human performance model that assumes that performance expectations, timely feedback, adequate environment, incentives, and skills and knowledge are required for a worker to perform well, this study explores how these conditions might affect healthcare provider performance in four countries. The study successfully shows that although multiple conditions were deficient or missing in every country, significant association is found between the performance of workers and conditions in the workers environment. Further, when viewed across all countries, non‐monetary incentives is the most powerful “predictor‘ of performance when compared with other factors. Of particular interest to Performance Improvement practitioners, knowledge and skills surfaced as important in only three of eight possible cases (with multiple cases in each country)—the least influential factor overall.  相似文献

Navigating OER: The Library’s Role in Bringing OER to Campus     

Julia I. Hess  Alejandra J. Nann  Kelly E. Riddle 《期刊图书馆员》2016,70(1-4):128-134

In 2014, three librarians at the University of San Diego came together to explore open educational resources (OER). Coming from both technical services and digital collections, we were well-versed in the economic challenges facing today’s libraries. In order to formulate the approach that would work best for our campus, we first had to educate ourselves on the past, present, and possible future of the Open Access movement. While traditionally Open Access has focused on serials, OER offer the opportunity to expand its benefits to other formats. This article examines opportunities and tensions surrounding OER, as well as highlighting major players on the OER landscape. Our efforts began with a focus group for faculty to assess their own knowledge of and opinions on OER. After establishing a stipend budget, we sent out a call for proposals to faculty who were interested in participating in the Copley OER Initiative.  相似文献
