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
The impact of example comparisons on schema acquisition: Do learners really need multiple examples?
Comparing multiple examples within problem categories is usually considered a necessary prerequisite for schema acquisition. However, there is an evident lack of conclusive empirical evidence supporting this claim. Moreover, there are findings indicating that carefully designed one-example conditions may allow for profitable processes of example comparison as well. In line with this reasoning, we present an experiment - that builds up on a series of studies conducted by Quilici and Mayer (1996)
Cognitive tools for discovery learning
Cognitive tools, defined here as instruments that support or perform cognitive processes for learners in order to support learning, can bridge the difference between open learning environments, like discovery learning environments and traditional supportive instructional environments. This article discusses a definition of the concept of cognitive tool and its use in learning. Two examples of cognitive tools for discovery environments are presented, and it is made clear how these tools can serve
Problems and Opportunities of Learning together in a Virtual Learning Environment
This chapter explores new ways of collaborative learning in a virtual learning environment based on our acquisition of knowledge from previous experience. We identify both the problems faced in real collaborative learning practices and the ways these problems can be overcome and become opportunities for more efficient learning. These issues concern pedagogical, organisational and technical elements and constraints that influence the successful application of collaborative learning in distance ed
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
22.68J Superconducting Magnets (MIT)
This course focuses on one important engineering application of superconductors -- the generation of large-scale and intense magnetic fields. It includes a review of electromagnetic theory; detailed treatment of magnet design and operational issues, including "usable" superconductors, field and stress analyses, magnet instabilities, ac losses and mechanical disturbances, quench and protection, experimental techniques, and cryogenics. The course also examines new high-temperature superconductors
Internet Scout Project
Chicago's Field Museum of Natural History (FMNH) Web site currently features museum-sponsored research on the phylogeny of Madagascar's living Carnivora. Previously thought to represent two to four separate lineages, the island's carnivores are now known to have descended from a single species. These findings, recently published in the journal Nature, are presented in the FMNH Web site as a 4-page press release that should appeal to general readers as well as interested researchers.
8.022 Physics II: Electricity and Magnetism (MIT)
Course 8.022 is one of several second-term freshman physics courses offered at MIT. It is geared towards students who are looking for a thorough and challenging introduction to electricity and magnetism. Topics covered include: Electric and magnetic field and potential; introduction to special relativity; Maxwell's equations, in both differential and integral form; and properties of dielectrics and magnetic materials. In addition to the theoretical subject matter, several experiments in electric
3D Digital View of Los Amigos Conservation Area
The availability of the Digital Elevation Model now allows for a carefully directed research design for sampling biotic and abiotic diversity. With an emphasis on plant diversity, the Los Amigos Botany team, consisting of an international group of Ph.D. scientists, graduate students, undergraduate students, and local field collaborators, will run landscape-scale transects that traverse a diversity of habitats.
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
The UChannel (also known as the University Channel) makes videos of academic lectures and events from all over the world available to the public. It is a place where academics can air their ideas and present research in a full-length, uncut format. Participating universities contribute video and audio recordings of lectures, seminars, panels and interviews to a virtual pool of academic content. Participants produce their own content, under their own name. The UChannel provides the audience for
Lecture notes for 1st semester are on titrations, gravimetry, kinetics and electrochemistry (redox). Potentiometry, coulometry, voltammetry, spectroscopic and separation methods are presented during 2nd semester, illustrated with QuickTime animations.
Dr. Carol Miller - Academic Spotlight
Dr. Carol Miller, distinguished professor of business law, was recently selected as the recipient of the Women's Justice Legal Scholar award. The award is presented by the Missouri Lawyer's Weekly Media. The Legal Scholar award is awarded to women faculty members or administrators who have fulfilled the women's justice ideals through their own work with the justice system through their research or scholarship, or through teaching and inspiring others. The award recognizes women across Missouri

Auburn vs. Alabama (1953)
"The two best teams in the SEC met for their annual intrastate battle in Birmingham with a "Winner Take All" situation facing them. Both teams had strong offenses and stout defenses. The defenses played the major role in the game however, as neither team could muster more than one touchdown drive. The X and Y teams played outstanding ball and deserved to win this, the most important game of the season. Dooley's x unit was probably the more effective that afternoon, but Vince was injured in the t
