What is wrong with knee replacement?
Modern knee replacement is a highly successful operation, relieving the pain and disability of knee osteoarthritis. However, it has limitations and these, combined with the changes in population demographics, present significant challenges for both current and future healthcare systems. Professor Richie Gill's inaugural lecture 'What is wrong with knee replacement?' explores these issues and the research being done to overcome them.Author(s): No creator set

Machines that change climate: Porsche 911 Turbo vs. Toyota Prius
This activity asks students make 'back-of-the-envelope' calculations to estimate the amount of carbon dioxide released to the environment by different types of automobiles. It shows students that decisions they make can significantly alter the amount of greenhouse gases they release to the environment. It also helps students learn about exponential growth by calculating how the money saved by purchasing an inexpensive car can be invested to great advantage. The exercise is designed for non-scien

The First Decade of Informatics in Dutch High Schools
Informatics is currently being taught in high schools all over the world. In the Netherlands, where all students are expected to become computer literate in the lower grades of high school (Hulsen et al., 2005), it has been decided not to consider computer literacy as being part of Informatics. What, then, should be the content of the Informatics curriculum taught in the higher grades? What should be taught, how and to whom? How should students' achievements be assessed? The answers to these que

Crime, Heredity and Insanity in American History
This course will give students an opportunity to learn more about the ways in which Americans have thought about crime and insanity and how their ideas have changed over time. The 19th century witnessed a transformation in the understanding of the origins of criminal behavior in the United States. For many, a religious emphasis on humankind as sinful gave way to a belief in its inherent goodness. But if humans were naturally good, how could their evil actions be explained? Drawing on studies don

Flow Rates of Faucets and Rivers
In the Flow Rate Experiment, students perform hands-on experiments with a common faucet, as well as work with the Engineering Our Water Living Lab to gain a better understanding of flow rate and how it pertains to engineering and applied science. Students calculate the flow rate of a faucet for three different levels (quarter blast, half blast, and full blast). Building on these calculations, students hypothesize about the flow rate in a nearby river, and then use the Engineering Our Water Livin

Pollution Solutions
To develop an understanding of modern industrial technologies that clean up and prevent air pollution, students build and observe a variety of simple models of engineering pollutant recovery methods: scrubber, electrostatic precipitator, cyclone and baghouse. In an associated literacy activity, students become more aware of global environmental problems and play a part in their solution by writing environmental action campaign letters.

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.

Enhancing the Adaptivity of an Existing Website with an Epiphyte Recommender System
In this paper we propose an approach to enhance the adaptivity of an existing Website by plugging on top of it (“epiphyte approach”) a recommender system that displays additional tips and functionalities in a separate window. The recommender system analyzes the way the user browses through the Website according to predefined prototypical ways of using the Website (“models of use”) and then proposes information or functionalities that appear useful according to this model of use.

Implementation of a computer algebra based assessment system
This article describes the design and implementation of the CABLE computer aided assessment system. Introducing a computer algebra system (CAS) to assist in marking allows instructors to design effective assessment schemes that are valid and reliable. A modular design approach allows system components, including a virtual learning environment (VLE), CAS and database, to be used for their respective strengths.
