This lesson plan looks at the major ideas in the Declaration of Independence, their origins, the Americans' key grievances against the King and Parliament, their assertion of sovereignty, and the Declaration's process of revision.

This collection uses primary sources to explore the Declaration of the Rights of Man and of the Citizen. Digital Public Library of America Primary Source Sets are designed to help students develop their critical thinking skills and draw diverse material from libraries, archives, and museums across the United States. Each set includes an overview, ten to fifteen primary sources, links to related resources, and a teaching guide. These sets were created and reviewed by the teachers on the DPLA's Education Advisory Committee.

In this activity students analyze a timeline and official and unofficial documents that reveal the events of the Iran-Contra Affair. This activity also models the types of questions that can help students analyze foreign policy documents from other events. The activity instructions include suggestions for how to differentiate the activity for students with different reading levels.

This video explains design of the Arecibo Message transmitted in the 1970s by SETI pioneers.

This short video and interactive assessment activity is designed to teach second graders about decomposing decimals into place values up to hundredths.

This short video and interactive assessment activity is designed to teach second graders about decomposing decimals into place values to tenths.

Are you bored by textbooks? Are you overwhelmed trying to keep up with the reading in all your college classes? Deconstructing Management is a podcast created by college students for college students. We make learning management not suck. Each episode is produced by different teams of students and aligns with the OpenStax Principles of Management textbook. We believe it's a better way to learn management, but we might be biased ;-)

Sal discusses the conditions of matrix dimensions for which addition or multiplication are defined. Created by Sal Khan.

Students learn about nanocomposites, compression and strain as they design and program robots that compress materials. Student groups conduct experiments to determine how many LEGO MINDSTORMS(TM) NXT motor rotations it takes to compress soft nanocomposites, including mini marshmallows, Play-Doh®, bread and foam. They measure the length and width of their nanocomposite objects before and after compression to determine the change in length and width as a function of motor rotation.

This art history video discussion examines Edgar Degas' "The Bellelli Family", 1858-67, oil on canvas (Musee d'Orsay, Paris). Degas was in his mid-twenties when he painted this canvas. It depicts from left to right, the ten-year-old Giovanna, her mother, the artist's paternal aunt Laura, her younger daughter, Giula age 7, and the Baron Gennaro Bellelli. Preperatory sketches for the painting may have been made in Florence where the family was living, the Baron had been exiled from Naples. The picture may have been completed in Paris.

This art history video discussion examines Edgar Degas' "The Dance Class" oil on canvas, 1874 (Metropolitan Museum of Art).

This art history video discussion examines Edgar Degas' "At the Races in the Countryside", 1869, oil on canvas, 36.5 x 55.9 cm / 14-3/8 x 22 inches (Museum of Fine Arts, Boston).

This art history video discussion examines Edgar Degas', "Visit to a Museum", c. 1879--90, oil on canvas, 91.8 x 68 cm / 36-1/8 x 26-3/4 inches (Museum of Fine Arts, Boston).

This art history video discussion examines Eugene Delacroix's "Scene of the Massacre at Chios": Greek families awaiting death or slavery, 1824 Salon, oil on canvas, 164" x 139" (419 cm x 354 cm) (Musee du Louvre, Paris) .

This art history video discussion examines Eugene Delacroix's "The Death of Sardanapalus", 1827, oil on canvas (Musee du Louvre, Paris).

The design of concurrent distributed hardware systems is a major challenge for engineers today and is bound to escalate in the future, but engineering education continues to emphasize traditional tools of logic design that are just not up to the job. For engineers tackling realistic projects, improvised attempts at synchronization across multiple clock domains have long been a fact of life. Prone to hazards and metastability, these ad hoc interfaces could well be the least trustworthy aspects of a system, and typically also the least able to benefit from any readily familiar textbook techniques of analysis or verification.

Progress in the long run depends on a change of tactics. Instead of the customary but inevitably losing battle to describe complex systems in terms of their stepwise time evolution, taking their causal relationships and handshaking protocols as a starting point cuts to the chase by putting the emphasis where it belongs. This way of thinking may call for setting aside a hard earned legacy of practice and experience, but it leads ultimately to a more robust and scalable methodology.

Delay insensitive circuits rely on local coordination and control from the ground up. The most remarkable consequence of adhering to this course is that circuits can get useful things done without any clock distribution network whatsoever. Because a handshake acknowledgment concludes each interaction among primitive components and higher level subsystems alike, a clock pulse to mark them would be superfluous. This effect can bring a welcome relief to projects whose timing infrastructure would otherwise tend to create more problems than it solves.

The theory of delay insensitive circuits is not new but has not yet attracted much attention outside of its research community. At best ignored and at worst discouraged in standard curricula, this topic until now has been accessible only by navigating a sea of conference papers and journal articles, some of them paywalled. Popular misconceptions and differing conventions about terminology and notation have posed further barriers to entry. To address this need, this book presents a unified account of delay insensitive circuits from first principles to cutting edge concepts, subject only to an undergraduate-level understanding of discrete math. In an approachable tutorial format with numerous illustrations, exercises, and over three hundred references, it guides an engineering professional or advanced student towards proficiency in this extensive field.

In our daily lives we use hundreds or even thousands of products and services. They are all designed, some with more success than others. The ‘Delft Design Approach’ is a structured approach that helps designers to tackle complex design challenges: from formulating a strategic vision, to mapping user behaviors, their needs and their environment, to developing and selecting meaningful proposals for products and services.

DDA691x offers a college-level introduction to the Delft Design Approach through lectures and exercises on design fundamentals and 6 methods. You will understand basic models and concepts that underlie the Delft approach. You will also develop the capability to use 6 basic methods in a design context. You will do so by applying the methods to realistic design challenges and by reflecting on your own performance by comparing it to that of expert designers as well as through peer discussion.

In dredging, trenching, (deep sea) mining, drilling, tunnel boring and many other applications, sand, clay or rock has to be excavated. This book gives an overview of cutting theories. It starts with a generic model, which is valid for all types of soil (sand, clay and rock) after which the specifics of dry sand, water saturated sand, clay, atmospheric rock and hyperbaric rock are covered. For each soil type small blade angles and large blade angles, resulting in a wedge in front of the blade, are discussed. For each case considered, the equations/model for the cutting forces, power and specific energy are given. The models are verified with laboratory research, mainly at the Delft University of Technology, but also with data from literature.

Delftse Foundations of Computation is a textbook for a one quarter introductory course in theoretical computer science. It includes topics from propositional and predicate logic, proof techniques, set theory and the theory of computation, along with practical applications to computer science. It has no prerequisites other than a general familiarity with computer programming.
