A methodological alternative to media comparison studies: Linking information utilization strategies
Literature reviews on hypermedia learning have yet failed to show consistent positive effects of learner-controlled nonlinear information access. We argue that a possible reason for this lack of evidence in favor of hypermedia learning results from the fact that not sufficient attention is paid to the strategies of information utilization learners deploy. The few studies that do analyze these strategies fail to link them to an instructional approach, which hampers a deeper interpretation of stra
Grid and Peer-to-Peer middleware for Cooperative Learning Environments
This paper presents the work done by the research group of the Open University of Catalonia within the coordinated project towards the definition of adequate grid and peer-to-peer middleware for cooperative learning environments. The main results of our research consist in designing a layered framework for modelling online collaborative learning interactions which in turns leads to the development of a computational platform, called Collaborative Learning Purpose Library (CLPL), that can be used
International Nutrition
Presents major nutritional problems that influence the health, survival, and developmental capacity of populations in developing societies. Covers approaches implemented at the household, community, national, and international levels to improve nutritional status. Explores the degree to which malnutrition can be prevented or reduced prior to achieving full economic development through targeted public and private sector interventions that address the causes of malnutrition.

This volume has some general topics for the whole ancient county of Middlesex except the city of Westminster, and articles on 7 parishes. Part of the area now lies within the London Borough of Hounslow, the rest within London boroughs in Surrey
Papers of George Washington
In this section of our site, we have endeavored to provide teachers and students with useful primary and secondary materials to help foster understanding of early America through the life of George Washington. These resources can work on several levels. First, the twelve slides themselves provide a general chronology of the life of George Washington as well as secondary information on the larger historical context. Ideally, this background material reiterates your own class text readings and dis

Musical Games (Part 1)
Two musical games for use with children at all levels. One game is based on rhythm patterns while the other is based on responding with movement.
Social Capital and the Distribution of Household Income in the United States: 1980, 1990, and 2000
Social capital is a person or group's sympathy or sense of obligation for another person or group. The objects of sympathetic feelings have social capital. Those holding sympathetic feelings for others provide social capital. Because social capital providers internalize the consequences of their choices, they trade with each other on different terms and at different levels that would occur in arm's length transactions, all other things equal. But changes in the terms and level of trade al
Digital Documentation: Merging the Traditional Laboratory Experience with Digital Imaging Technology
In this investigation, students will become proficient in the use of integrated digital technology as they capture images of exemplary specimens with digital microscopes. Students can later use these images individually to compose and illustrate original lab manuals (digital notebooks) or in collaborative groups to design multimedia presentations. Students actively engage in their learning and participate in high levels of cognitive functioning as they construct knowledge about the phyla they ar
Hundred Board Activities 1
Students learn the patterns in the hundred board by assembling puzzles. Teachers are able to assess student use of patterns in rows and columns by observing the student at work. This task is easily differentiated to accommodate the varied levels in a first grade class by changing the number of pieces and the shape of the pieces. Puzzle bags should be sequentially lettered so that students progress through harder versions of the task. Finally, students are asked to create their own puzzles for cl
Instructional Strategies for Mental Math
These strategies support active student participation in math lessons and allow teachers to assess the developing proficiency levels of all students in the class by walking around to monitor student responses. These strategies are especially effective during the Mental Math part of an Everyday Mathematics lesson.
Towards a targeted surfactant stabilized ultrasound contrast agent
Gas-filled microbubbles are highly effective when used as ultrasound contrast agents due to the large difference in acoustic impedance between the gas in the bubble and the surrounding blood. The surfactant-based contrast agent ST68 (Span 60, Tween 80) developed in our laboratory (US Patent # 5, 352, 436) and filled with sulfur hexafluoride (SF6), was modified in an attempt to make the agent target specific. Modifications to the agent were done by incorporation an anchor molecule, phosphatidylet
Biomechanical evaluation of the intact, injured and surgically reconstructed ulnar collateral ligame
The ulnar collateral ligament (UCL) of the elbow is a major passive stabilizer againstvalgus moments and is a frequent site of injury for the professional throwing athlete. Due to theimportance of the UCL in elbow stabilization, many clinical and biomechanical studies wereconducted in the past to understand its role; however, no study has evaluated the stabilizingfunction of the UCL when subjected to a pure valgus-varus moment at varying degrees of flexion.In addition, few comparative studies ha
Spectroscopic Simulator
This applet covers an aspect of the Physical Chemistry II course that students often find confusing. Although it is based on relatively simple mathematics, a complete understanding of the phenomenon requires assimilating the following concepts: The energy levels of a diatomic molecule are given by the formula: E(v,J) = hv (v + ½) + BJ (J + 1); v = 0..infinity, J=0..infinity. A molecule absorbs light at frequencies that correspond to difference between energy levels. In this case, we are interes
Organization of Parties
Political parties in America are organized much like the federal government—each has offices at the national, state, and local levels. Each level has a committee and chairperson to oversee party activities. (Video is narrated with slides and speeches.)
SIMply Prairie: Prairie Advocates
In this multidisciplinary, inquiry-based project students prepare a plan and give a persuasive oral presentation to create a reconstructed prairie based on research. Teachers can use this unit with their students to justify enlarging or keeping an existing prairie. This project can serve as the organizing structure for prairie study where materials from units such as The Prairie – Our Heartland become research materials. It can be used in conjunction with the unit which is taught best in the f
