Mixing Microworld and Cas Features in Building Computer Systems that Help Students Learn Algebra
We present the design principles for a new kind of computer system that helps students learn algebra. The fundamental idea is to have a system based on the microworld paradigm that allows students to make their own calculations, as they do with paper and pencil, without being obliged to use commands, and to verify the correctness of these calculations. This requires an advanced editor for algebraic expressions, an editor for algebraic reasoning and an algorithm that calculates the equivalence of
Red Rover Robotics
This lesson begins with a brief history of robotics, describing how robots are beneficial to engineering and society and then explores how robots have been used in recent space exploration efforts. The engineering design of the two Mars rovers, Spirit and Opportunity, are examples of advanced engineering design for space research. The maneuverability of these two spacecraft's robotic arms and the functionality of their tools is discussed.
The Amazing Red Planet
The purpose of this lesson is to introduce students to the planet Mars. This lesson will begin by discussing the location and size of Mars relative to Earth, as well as introduce many interesting facts about this red planet. Next, the history of Martian exploration is reviewed and students discover why scientists are so interested in studying this mysterious planet. The lesson concludes with students learning about future plans to visit Mars.
Landfills: Building Them Better
Waste disposal has been an ongoing societal problem since medieval times. In this lesson, students learn about the three methods of waste disposal in use by modern communities. They also investigate how engineers design sanitary landfills to prevent leachate from polluting the underlining groundwater.
A River Ran Through It
Students learn how water is used to generate electricity. They investigate water’s potential-to-kinetic energy transformation in hands-on activities about falling water and waterwheels. During the activities, they take measurements, calculate averages and graph results. Students also learn the history of the waterwheel and how engineers use water turbines in hydroelectric power plants today. They discover the advantages and disadvantages of hydroelectric power. In a literacy activity, students
Utopian Hope and Apocalyptic Religion
Editor's note: The original event recording started slightly after the beginning of the introduction by Professor Lord Meghnad Desai. Where does the utopian impulse in politics originate, and does it have a future? John Gray argues that though they often claimed to be rooted in a scientific analysis of history and society the revolutionary political movements of the past were informed by a utopian vision which derives from religion. Is the age of secular utopianism over, and if so how will relig
Professor Paul Franco, Sep. 8, 2006

Mr. Franco is the author of The Political Philosophy of Michael Oakeshott, Hegel’s Philosophy of Freedom, and most recently Michael Oakeshott: An Introduction.
Reading picture books
Two strategies for helping children understand a story through illustrations.
A History of the County of Wiltshire: Volume 17 Calne
Calne, a small town in north Wiltshire, stood on a large royal estate, and the witan met there - St Dunstan survived the partial collapse of a building at one meeting.
Pairwise Comparisons in SAS and SPSS
This site provides information for SAS or SPSS software users, who would like to use multiple comparison methods available in either software package to carry out pairwise comparisons. The site provides a short description of available methods and a recommendation based on the comparisons of the procedures. Some of the methods, namely step-down Holm-Bonferroni and Holm-Sidak, are not directly available in SAS or SPSS, but can be easily implemented using results of appropriate SAS or SPSS procedu
The purpose of this resource is to observe budburst on selected trees at a Land Cover or Phenology Site. All students will learn about hummingbird natural history and ecology. Students will learn how to identify and age male and female Ruby-throated Hummingbirds and to observe migration and feeding behavior. Students will learn how to make connections among hummingbird behavior and weather, climate, food availability, seasonality, photoperiod (day length), and other environmental factors.
The Nuts and Bolts of Empire
All great empires have required a sophisticated logistical system, and a secure communications system to sustain themselves. In a world of endless challenges imperial ambitions soon collapse. This lecture will examine the hard, infrastructural underpinnings of the Roman, Spanish and British Empires, and reflect on how the USA compares in this regard. Paul Kennedy is J Richardson Dilworth Professor of History at Yale University and Philippe Roman Chair in History and International Affairs at LSE.
The Pivot of the 20th Century
Winston Churchill said in 1945 that 'the United States stands at this moment at the summit of the world'. Yet just five years earlier America had been an economic catastrophe and an isolationist bastion. How that transformation came about, and its consequences, will be the subject of this lecture. David M Kennedy is Donald J McLachlan Professor of History at Stanford University.
Hot, Flat and Crowded
Thomas L Friedman takes a fresh and provocative look at two of our biggest challenges - the global environmental crisis and America's surprising loss of focus and national purpose since 9-11 - and shows how they're linked. He argues that we need American commitment and leadership in a green revolution, a revolution that will be the biggest innovation project in history, one that will inspire us to summon all the intelligence, creativity, boldness and concern for the common good that are our grea
In Sickness and In Power
The course of world history has been critically shaped by the physical and mental illnesses of heads of state, sometimes in the public eye but usually in secrecy. Long fascinated with the inter-relationship between politics and medicine, David Owen uses his deep knowledge of both to undertake a unique study of illness in Heads of Government during the last 100 years. Owen expertly scrutinises such diverse political personalities as Sir Anthony Eden at the time of Suez in 1956; John F. Kennedy an
Black Panther, the revolutionary art of Emory Douglas
Emory Douglas, ex Minister of Culture for the Black Panther party, will speak about the history behind the art of the party, and take a look at some more recent works. Emory Douglas was born May 24th, 1943 in Grand Rapids, Michigan. Douglas attended City College of San Francisco where he majored in commercial art. He was politically involved as Revolutionary Artist and then Minister of Culture for the Black Panther party in Oakland, CA from February, 1967 until its discontinuance in the Early
Kosovo's Independence and the Balkans: regional implications and challenges
Uncertainty over the status of Kosovo had undermined stability in the Balkans since the early 1990s. The panel of experts discusses Kosovo's declaration of independence and its political, economic and security impact on the Balkans. Jelena Bjelica is the editor-in-chief of the weekly Gradjanski Glasnik, Kosovo. Anna Di Lellio is the editor of the book The Case for Kosova: passage to independence. Enver Hoxhaj is the current minister of education, science and technology of the Republic of Kosovo.
Keeping Score: new approaches to the standard of living
Measuring social performance is an important task in the social sciences, and the complexity of the problem has given rise to numerous approaches. In this lecture, Professor Steckel will discuss the use of anthropomorphic measures in this field, and explain the advantages of height as a measure of standard of living. Richard H Steckel is SBS Distinguished Professor of Economics, Anthropology and History at Ohio State University. The Space for Thought Lecture series celebrates the completion of t
The Islamic Republic of Iran After 30 Years
Thirty years after the fall of the Shah of Iran and the advent of Ayatollah Khomeini to power, the Iranian revolution continues to exert a dynamic ideological and political influence across the Middle East. In a retrospective analysis of the revolutionary period itself, some of whose decisive moments he witnessed at first hand, and of the subsequent development of the Islamic Republic Professor Fred Halliday will attempt to set these dramatic events in context, as much that of the comparative st
