What Predicts Middle School Girls' Interest in Computing?
No full textIn this 17 page article from the International Journal of Gender, Science and Technology, researchers analyzed data from 140 Latina and Caucasian girls in a California middle school during the first day of an IT-intensive after school program. They found that a young womanâs interest in computer science could be predicted from her curiosity about technology and the support of her peers and teachers
Introduction to Alternative and Renewable Energy: Introduction and Energy Statistical Data Module
No full textThis module is intended for use in a college-level introductory course in alternative and renewable energy. The document includes an overview of energy, details on US and world energy consumption statistics as well as alternative and renewable energy statistics. The material includes useful data and a number of graphical representations of the information. This module may be downloaded in PDF file format
FOA Lecture 23: Total Internal Reflection in Optical Fiber
No full textThis is Lecture 23 in the Fiber Optics Association's series of lectures on fiber optics. In this lecture, the presenter discusses "refraction" and "total internal reflection," the optical terms for how light is bent or reflected at the boundary of two different materials. Total internal reflection is important in fiber optics as it is the reason that light can be trapped in the core of the fiber, making optical fiber transmission possible. Using a visible red laser from a VFL, the video demonstrates total internal reflection in a large core plastic fiber. Running time for the lecture is 5:03. Flash is required to view the video
Tsunami Visualizations
No full textThis collection provides a wide array of visual resources and supporting material about the December 26, 2004 Indian Ocean Tsunami. Visualizations include simple animations, satellite photographs, Quicktime animations and tsunami models. The collection also contains visualizations related to other historical tsunamis and additional resources (beyond visualizations) about tsunamis. Resources can be incorporated into lectures, labs, or other activities
Wetlands Management I - Determination and Delineation
No full textThis instructional guide is designed to provide instructors with lecture and laboratory materials that introduce the concepts and practices of wetland determination and delineation. Student objectives, a general lecture outline and a more detailed PowerPoint presentation with instructor notes are provided. Criteria for the identification of wetlands and accepted delineation methods as established by the U.S. Army Corps of Engineers are reviewed including field indicators of hydric soils, hydrology and wetland vegetation. Various sources of archived information commonly used in wetland determination and delineation are also described. A combination laboratory/field exercise is also fully described that guides students through a hands-on experience to illustrate how determinations are performed and how the boundaries of a wetland are defined. Instructors who are looking for videos or additional print and web-based resources on the topics covered here should consult the resources list provided at the end of this module where these resources are summarized and cited.Upon successful completion of this module students should be able to:* Distinguish between âwetland determinationâ and âwetland delineationâ* Describe the need for wetland identification and delineation in wetland management* Identify current and archived sources of information that could be accessed to perform a wetland determination or delineation* Describe field indicators of wetlands based on soils, hydrology and vegetation criteri
Wetlands - An Introduction
No full textThis instructional guide is designed to provide instructors with lecture materials and resources that introduce wetlands as ecosystems. Student objectives, a general lecture outline and a more detailed PowerPoint presentation with instructor notes are provided. Wetland definitions and their importance are discussed as well as the criteria that are used to distinguish wetlands from uplands. The structural and physiological adaptations of wetland plants, wetland functions and the economic value of ecological services provided by wetlands are also presented. Instructors who are looking for videos or additional print and web-based resources on the topics covered here should consult the resources list provided at the end of this module where these resources are summarized and cited.Upon successful completion of this module students should be able to:* Distinguish between wetlands and uplands using soils, hydrological and vegetation criteria* Describe the structural and physiological adaptations of wetland plants* Describe the various ecosystem functions that are provided by wetlands* Evaluate the economic value of ecological services provided by wetland
Occupational Employment and Wages, May 2010: 17-3023 Electrical and Electronics Engineering Technicians
No full textThis is the background of employment numbers and wages for electrical and electronics engineering technicians complied by the Bureau of Labor Statistics; these are the latest numbers as of March 2011. This group is described as individuals who "apply electrical and electronic theory and related knowledge, usually under the direction of engineering staff, to design, build, repair, calibrate, and modify electrical components, circuitry, controls, and machinery for subsequent evaluation and use by engineering staff in making engineering design decisions." Number of individuals employed, mean hourly wage and mean annual wage are just some of the figures provided
Council on Undergraduate Research on the Web
No full textThe mission of the Council of Undergraduate Research (CUR) is to "support and promote high-quality undergraduate student-faculty collaborative research and scholarship." CUR disseminates some of its work and findings through the Council of Undergraduate Research Quarterly (CURQ) and this site provides access to some of the articles from that publication. Currently, visitors can search past articles back to 2008, and visitors can browse through articles like "Putting Undergraduate Research on the Map for Women," "Peer Mentoring in an Introductory Biology Laboratory," and "Undergraduate Research on Writing: Benefits to Faculty and Curriculum Development." All told, the site provides a cornucopia of articles related to making the undergraduate research experience a bit more meaningful, and educators will find much to enjoy here
Index of Refraction and Snellâs Law
No full textIn this video from the ICT Center, learn about the index of refraction and Snellâs law. Review a simple example of refraction, the speed of light in materials, and the formula for calculating the index of refraction. Explore a table of the refractive indices of common media and materials used in fiber optics and semiconductors. Finally, examine Snell's law to understand the relationship between incident and refracted angles.The video runs 4:04 and is accompanied by a background essay, standards alignment, and discussion questions. Users who sign up for a free account can save the resource and download the video as well
Introduction to Electric Power Systems
No full textThis fine course is offered as a welcome addition to MIT's OpenCourseWare initiative. The materials from this version of "Introduction to Electric Power Systems" are from the iteration taught by Professor James Kirtley in Spring 2011.
