Study Goals: Students learn about renewable energy sources, name
Cavitation on Ship Propellers
Summary: Cavitation is the transition of a fluid into vapour due to local reduction of pressure which is generated by high local flow velocities. The transition of a fluid into vapour also occurs during cooking of water by an increase of the local temperature. The term cavitation is generally reserved for conditions in which the temperature of the bulk fluid is not changed. Although cavitation can occur in many situations this course focuses on ship hydrodynamics and ship propellers. The course

This a 2-day short course on Fluidics on a Compact disc for medical diagnostics. The course is intended for scientists and engineers in academia, government institutes and industry. Some background in physics, micro-fluidics and point of care (POC) diagn
Implementing the Challenge Based Learning in Classroom Scenarios
Our Challenge Based Learning (CBL) method can be described as a special form of problem-based learning, in which the problems are of realistic, open-ended nature. Additionally, CBL contains features of experiential and project-based learning approaches. CBL is supported by the provision of Digital Experimentation Toolkits (DExTs) which comprise materials, initial instructions, references to web resources and specific software tools. Within the COLDEX project, a number of remote sites which gener
From mirroring to guiding: A review of the state of art technology for supporting collaborative lear
We review systems that support the management of collaborative interaction, and propose a classification framework built on a simple model of coaching. Our framework distinguishes between mirroring systems, which display basic actions to collaborators, metacognitive tools, which represent the state of interaction via a set of key indicators, and coaching systems, which offer advice based on an interpretation of those indicators. The reviewed systems are further characterized by the type of inter
Internet Scout Project
With the exception of orchestral performances and truly "unplugged" concerts, today's music has evolved into a very hi-tech industry. It takes elements from many disciplines, including computer science, electrical and mechanical engineering, mathematics, and physics. Because music technology encompasses everything from audio compression and encoding to advanced sound equipment, this Topic in Depth has quite a broad scope.A decent introduction to some aspects of music technology (1) mainly deals
Shared conceptualisations in weblogs
In this paper we investigate how conceptualisations can be identified in weblogs using language technology (automated text analysis). We focus on getting a handle on both the concepts bloggers use and the way they think these concepts are related. The analysis of these conceptualisations can then be applied to a single weblog, resulting in a visualisation of potential conceptualisations the blogger wants to share with the outside world. Another type of analysis is to determine the overlap, or sh
From Stargazers to Starships
This is a self-contained book-on-the-web course on basic astronomy, Newtonian mechanics, the sun (and associated physics), and spaceflight and spacecraft. covers elementary astronomy, Newtonian mechanics, the Sun and related physics and spaceflight. Also included are a Spanish translation, 46 lesson plans, a short but complete math course (algebra + trig), teachers' guides, glossary, timelines, 345 questions (current tally) by users and their answers, over 100 problems to solve, and more.
Using Stress and Strain to Detect Cancer!
This module was written for a first year accelerated or AP physics class. It is intended to provide hands-on activities to teach the concepts of stress, strain and Hooke’s law. During the unit, students will apply the concepts learned through the lessons to solve the following engineering challenge: Breast cancer is the second-leading cause of cancer related death among women (Papas, 253) and the American Cancer Society has indicated that mammography is the best early-detection tool available.
Data Plotting and Fitting
This Data Plotting and Fitting page was developed as a third year laboratory for the School of Physics, University of New South Wales. The program will plot data into several different graphs. Graphs include a line graph, linear regression fit, exponential fit, power fit, Gaussian fit and Cos squared fit. The program can also calculate fit for the data if required.
Conservation Ecology: Lessons from the physics education reform effort
Starting in 1992, introductory physics students at Indiana University were pre- and post-tested on their knowledge of general physics. Some students received standard classes of lectures and tests, while others were taught using interactive engagement (IE) techniques. The goal of the study was this: can IE methods increase the effectiveness of introductory mechanics courses? Though the study focused on physics and mechanics specifically, the techniques used can be applied in teaching other scien
This site from SERC describes ConcepTests, which are conceptual multiple-choice questions that were originally designed by Eric Mazur at Harvard University for students in large physics classes. ConcepTests are generally short, and as they are multiple-choice, they are useful for immediate quantitative assessment of student understanding. It may be useful to the instructor to know how many correct responses there are to a question both before and after peer instruction to better gauge student un
Soil Science and Technology Home Page
This site looks at soil fertility, nitrogen in soil, soil chemistry, soils as electrical systems, soils as filters, soil physics and particle sizes (silt, sand, and clay), microorganisms in soil, nutrients that plants need, soil morphology, judging soil by feel, structures and shapes of soil, and soil profile images from Arizona, Florida, Michigan, and other states. Learn how soil is formed and how long it takes to create an inch of soil.
