Allies during World War II, the U.S. and the Soviet Union disagreed over a number of issues after the war. These included control of Eastern Europe, division of Germany, atomic energy, international loans, and the Middle East. On February 9, 1946, Soviet premier Josef Stalin asserted that the continued existence of capitalism in the West would inevitably lead to war. Foreign Service senior diplomat George Kennan sent President Harry Truman, still forming a Soviet policy, a lengthy telegram advocating containment. Commerce Secretary Henry A. Wallace--Secretary of Agriculture (1933-1941) and Vice-President from (1941-1945)--was one of the few liberal idealists in Truman's cabinet. Wallace envisioned a "century of the common man" marked by global peace and prosperity. In the following excerpt from a letter dated July 23, 1946, Wallace urged Truman to build "mutual trust and confidence" in order to achieve "an enduring international order." Truman asked Wallace to resign. In March 1947, Truman asked Congress for money "to support free peoples who are resisting attempted subjugation by armed minorities or by outside pressures." Thus articulated, the "Truman Doctrine" of containment served as the rationale for future American Cold War foreign policy initiatives.

In this "clicker case," a three-year-old girl gets into the medicine cabinet and ingests an unknown number of aspirin tablets. Her brother calls 911 and the girl is taken to a nearby hospital, where she is treated. The case is used to discuss the Law of Mass Action, chemical equilibrium and equilibrium constants, pH, and weak acids and buffers in the context of medical management of a life-threatening emergency. It is called a "clicker" case because it is designed to be presented in a class that uses personal response systems, or "clickers." The case is presented via a series of PowerPoint slides (~400KB) punctuated by multiple-choice questions, which the students answer using their clickers. It could be adapted for use without these technologies. The case is suitable for use in an introductory biology course where integration with biologically relevant chemistry is an important course objective. It could also be used in a chemistry course.

In this project, students explore how levers work, by making a puppet with moving limbs. After showing students how to make the arms, students are challenged to construct the rest of the puppet on their own. This activity engages learners in a way that is educational, fun, and encourages creativity.

This course covers techniques for and critical thinking about the evaluation of changes in educational practices and policies in schools, organizations, and informal contexts. Topics include quantitative and qualitative methods for design and analysis, participatory design of practices and policies, institutional learning, the wider reception or discounting of evaluations, and selected case studies, including those arising from semester-long student projects.

Active Lessons are engaging, technology-based, student-centered (pupil-centered) learning activities designed by teachers using PowerPoint (or other presentation tool). The idea is to empower teachers to easily create technology-based activities that draw upon variety of existing and new digital resources from internet, repositories of learning objects and other sources, and require students to use technology and create artifacts demonstrating their understanding. This idea partially challenges WebQuest approach and proposes that instead of getting teachers to design web sites, more effective strategy would be to use a presentation tool to design in more productive way. Active Lessons are technologically simple because PowerPoint is used for design and there is no need to struggle with technicalities of web publishing. With reduction in technicalities teachers can concentrate on pedagogy. The central hypothesis in this proposal is that if teachers develop understanding of technology-supported pedagogy, technicalities will synch in naturally through experience and emerging needs.

The Malpighian tubules of insects are an excellent model for examining the properties of secretion in a transporting epithelium. In this exercise students expose tubules from cockroaches or crickets to chlorophenol red and visually estimate the dye concentration in the lumen. By adding metabolic inhibitors and competitors or by substituting ion-free media they can demonstrate competition, specificity, and energy- or ion-dependence of active transport. Advanced students can design their own experiments after a review of the literature. This simple and inexpensive exercise provides students with a challenging and rewarding introduction to experimental design in the laboratory.

Students study the patterns of bird flight and learn that four main forces affect the flight abilities of birds (lift, thrust, drag, gravity). They investigate the shape, feather structure and resulting differences in the pattern of flight. Then they look at several articles that feature newly designed planes and their bird inspirations. They watch the Nature documentary, "Raptor Force," which chronicles the flight patterns of birds, how researchers study these animals and what interests the military and aeronautical engineers about these natural adaptations. This activity serves as an extension to the biomimetics lesson. Although students will not be using this information in the design process for their desert resort, it provides interesting information pertaining to the current use of biomimetics in the field of aviation. Students may extend their design process by using this information to create a means of transportation to and from the resort, if they chose to.

This e-study gathers resources for practitioners who seek to design and implement culturally responsive evaluations. The study highlights the expansion of the field of evaluation to national and contexts where evaluation has been historically missing. In doing so, the study engages the learners in critical thinking about the nature and dissemination of evaluation evidence for decision-making that leads to equitable distribution of resources.

In this activity, learners explore the concept of how engineering has made possible the development of--and ongoing improvements to--adaptive devices that serve to help individuals with a wide range of physical challenges adapt to the world and participate fully in society. Learners investigate the engineering process to solve problems, and work in teams to improve the design of a current or proposed adaptive device. Learners start with eyeglasses, disassembling, examining component design and shape, and reassembling. Then, learners re-engineer the product seeking improvements to the current product.
