Self-directed learning in simulation-based discovery environments
SIMQUEST1 is an authoring system for designing and creating simulation-based learn-ing environments. The special character of SIMQUEST learning environments is that they include cognitive support for learners which means that they provide learners with support in the discovery process. In SIMQUEST learning environments we try to find the balance between direct guidance of the learning process and sufficient free-dom for learners to regulate the learning process themselves. In this article we de-
Students' adaptation to a new situation:
the design of an experimental procedure
Different studies (Arce and Betancourt, 1997; Séré, 2002) emphasize the importance of the task of experimental procedure design in a learning context. However, the required design is a difficult task for students (Séré and Beney, 1997). Consequently, students are hardly ever allowed to design their own experiment. The study by Tiberghien et al. (2001) showed that to learn how to plan an investigation in order to address a specific question or problem was the least frequent process object
Adaptive FIR Filtering
In this laboratory, students implement a real-time adaptive FIR filter, investigate the convergence of the least mean squares (LMS) algorithm, and apply the adaptive filter to the problems of system identification and echo cancellation.
Adaptive Filtering: LMS Algorithm
This module introduces adaptive filters through the example of system identification using the LMS algorithm. The adaptive filter adjusts its coefficients to minimize the mean-square error between its output and that of an unknown system.
Directory of Open Access Journals
Directory of Open Access Journals. This service covers free, full text, quality controlled scientific and scholarly journals. We aim to cover all subjects and languages. There are now 1964 journals in the directory. Currently 482 journals are searchable at article level. As of today 81975 articles are included in the DOAJ service. The aim of the Directory of Open Access Journals is to increase the visibility and ease of use of open access scientific and scholarly journals thereby promoting thei
3.2 - Clock System on the ez430
Describes how the clock system works on the ez430.
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
African Americans and the United States judicial system
Harvard law professor Alan Dershowitz comments on the inability for Black Americans to receive fair treatment in the United States judicial system.
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

Parts of a Corn Seedling
This illustrated guide to a corn seedling (Zea mays, Monocotyledon) is designed to help students recognize and learn the plant's individual parts. Along with an explanation of monocotyledon embryos, it includes a short description of the root system and coleoptile.
Make Your Own Astro Stationery
This OLogy activity gives kids a stellar way to present their thoughts with three ready-to-print letterheads, which are provided as downloadable PDFs.
This site features Flash animations that illustrate how the Global Positioning System (GPS) works. The animations depict how GPS signals are derived, compare geostationary and polar orbits, and explain satellites, ground control, and user segments, which comprise the three main GPS components. These resources are suitable for use in lectures, labs, or other teaching activities.
The Generative Multi-Performance Design System
This paper proposes a framework for an integrated computational design system. This design system builds on the strengths inherent in both generative synthesis models and multi-performance analysis and optimization. Four main design mechanisms and their mathematical models are discussed and their integration proposed. The process of building the design system begins by a top-down decomposition of a design concept. The different disciplines involved are decomposed into modules that simulate the r
This animation shows how velocity and position of an aircraft are resolved in a 3-D Cartesian coordinate system.
American Visionaries: Thomas Moran
features paintings and sketches of the noted American landscape painter. Moran's pencil and watercolor field sketches and paintings captured the grandeur and documented the extraordinary terrain and natural features of the Yellowstone region. His artwork was presented to members of Congress by park proponents and helped inspire Congress to establish the National Park System in 1916.
Allegheny Portage Railroad: Developing Transportation Technology
shows the innovative transportation system used in the 1820s-1840s to tow railroad cars up and down the steep slopes of the Allegheny Mountains.
Can Public Health Researchers and Agencies Reconcile the Push From Funding Bodies and the Pull From
Responding to growing impatience with the limited application of research findings to health practices and policies, both funding bodies and communities are demanding that research show greater sensitivity to communities’ perceptions, needs, and unique circumstances. One way to assure this is to employ participatory research—to engage communities at least in formulating research questions and interpreting and applying research findings and possibly also in selecting methods and analyzing dat
After the Civil War, freed slaves in the South faced an uncertain future. Economically destitute, they struggled to establish schools and buy their own land. The establishment of the sharecropping system, the rise of the Ku Klux Klan and the entrenchment of segregation made their chances for success remote. In 1877, when Reconstruction ended, and federal troops withdrew,Black families began to leave the South by the thousands, looking for a better future. They were called Exodusters. Excerpts fr
Enhancing Physics Knowledge for Teaching – Maxwell’s Equations
In this session we’re going to look at how electricity and magnetism can be unified into a system of equations, named after James Clerk Maxwell, the Scottish physicist who first proposed them. Then we’ll see how this leads to an understanding of the nature of electromagnetic radiation.
