Who's Protecting Public Health? Part 2
Local E. coli scares and a measles outbreak are fresh reminders that infectious diseases continue to be major causes of sickness and death. Bioterrorism and biological disaster are on everyone's mind. Keeping one step ahead of these killers is one of the greatest challenges facing medicine and public health.
Swinging with Style
Students experientially learn about the characteristics of a simple physics phenomenon the pendulum by riding on playground swings. They use pendulum terms and a timer to experiment with swing variables. They extend their knowledge by following the steps of the engineering design process to design timekeeping devices powered by human swinging.
The use of NLP tools for Basque in a multiple user CALL environment and its feedback
In this article, we present a Computer Assisted Language Learning (CALL) environment for Basque. The environment has different aims: on the one hand, to offer the users (teachers, learners and computational linguists) different tools and language resources to clarify the linguistic doubts they might have about the language, and on the other hand, to store information about language learners, deviations and errors as the basis for further studies in CALL and Natural Language Processing (NLP). The
A Framework System for Intelligent Support in Open Distributed Learning Environments
Recent trends in the design of learning support systems are characterized by considering group interaction, by combining intelligent support with interactive learning environments, by providing reusable domain-independent components, and by using agent-structured architectures. Taking these trends into account, an open framework system has been developed for integrating distributed intelligent support components with an interactive and collaborative learning environment. Work in shared activity
Balancing situativity and formality: the importance of relating a formal language to interactive gra
A situated cognition theory is presented in which situated learning is viewed from a Vygotskian perspective: the developmental situativity theory. It is assumed that learning is basically a non-symbolic inductive process that is greatly enhanced by formal systems which act as tools. Instruction should provide students with an environment containing elements to allow for situated activity as well as with appropriate formal tools. Tarski's World, which is an instructional Interactive Graphical Rep
Semantic Description of Grid Based Learning Services
Grid technology has emerged as a powerful tool to increase the capabilities of e-learning frameworks. Learning services are fundamental components representing functionalities that can be easily reused without knowing the details of how services have been implemented. On the one hand, a problem that still remains unsolved is how to use and integrate low-level learning services to compose more complex high-level services or tools that make sense to both tutors and learners. On the other hand, the
Enabling Students to Construct Theories of Collaborative Inquiry and Reflective Learning: Computer S
To develop lifelong learning skills, we argue that students need to learn how to learn via inquiry and understand the sociocognitive and metacognitive processes that are involved. We illustrate how software could play a central role in enabling students to develop such expertise. Our hypothesis is that sociocognitive systems, such as those needed for collaborative inquiry and reflective learning, can best be understood as a community of interacting agents, who each have expertise in accomplishin
Effects of pictures, age and experience on learning to use a computer program
This study examines the effects of pictures of screen captures and input devices on documentation for older novices. There was no main effect of pictures, but there were statistically significant interactions between the type of picture and the factors of age and computer experience. As predicted, the most optimized designsthe ones presenting screen capturesmoderated the negative effects of age. We argue that screen captures help reduce two problems in the cognitive area that are especially
Internet Scout Project
Developed by the Information Institute of Syracuse, the Educator's Reference Desk offers a large assortment of science lessons plans for students of all ages. This amazing resource covers topics in earth science, chemistry, space science, geology, physics, and physical science, as well as life science subjects. Besides scanning the hands-on activities created by teachers throughout the United States, visitors can search the abundant lesson plans by key words or education level. The website provi
Selecting Theories in an Ontology-Based ITS Authoring Environment
This paper introduces the rationale for concrete situations in the authoring process that can exploit a theory-aware Authoring Environment. It illustrates how Ontological Engineering (OE) can be instrumental in representing the declarative knowledge needed, and how an added value in terms of intelligence can be expected for both authoring and for learning environments.
Assembly of Proteins in Membranes I from the course General Biochemistry and Molecular Biology
General Biochemistry and Molecular Biology - Fall 2006. This course covers molecular biology of prokaryotic and eukaryotic cells and their viruses. Mechanisms of DNA replication, transcription, translation. Structure of genes and chromosomes. Regulation of gene expression. Biochemical processes and principles in membrane structure and function, intracellular trafficking and subcellular compartmentation, cytoskeletal architecture, nucleocytoplasmic transport, signal transduction mechanisms, and c
Introduction to Synchronous Digital Systems - Part II Fall 2007
Machine Structures - Fall 2007. The CS61 series is an introduction to computer science, with particular emphasis on software and on machines from a programmer's point of view. The first two courses considered programming at a high level of abstraction, introducing a range of programming paradigms and common techniques. This course, the last in the series, concentrates on machines and how they carry out the programs you write. The main topics of CS61C involve the low-level system software and th
Cyberinfrastructure for Education and Learning for the Future: a vision and research agenda
This report is the result of a series of workshops organized by the Computing Research Association and the International Society of the Learning Sciences with support from the National Science Foundation (Grant No. REC-0449247). The purpose of the workshop series was to explore where we are in the application of pervasive computing power to education, and where we need to be. In particular, the intent was to develop a map of where NSF can strategically place its resources in creating the learni
Huntington Archive of Buddhist and Related Art
This site contains nearly 300,000 slides and photos of Asian art and architecture. Materials are predominantly Buddhist but include Hindu, Jain, Islamic, and other works (dating back to 2500 BC). This archive is the most comprehensive collection of its kind. It includes the largest photo archive of Nepali art and architecture in the world and represents the only formal collection that photographically records Nepali's artistic heritage.
NIST Time and Frequency Information
The Time and Frequency Division, part of NIST's Physics Laboratory, maintains the standard for frequency and time interval for the United States, provides official time to the United States, and carries out a broad program of research and service activities in time and frequency metrology.

Pressure in a Graduated Cylinder
As you go farther below the surface of a fluid, the pressure increases. Professor Ephraim Fischbach demonstrates pressure in a graduated cylinder in this video from Thinkwell's online Physics series. Run time 03:18.
Mr Magoo-Noah's Ark-Part 2 of 3
In part 2 of this video, Noah, played by Mr. Magoo, continues to do as God commands--to build an ark, collect food, and gather 2 of every kind of animal. The family and animals become restless and begin bickering. This is a wonderful teaching resource for the Christian classroom, for a church function, and/or for home to share this special Bible story. It would also be beneficial for a study on ancient history (10:00)
