Nikos Valence on Organizing Against the North American Free Trade Agreement
During the 1980's and 1990's international free trade agreements encouraged by the United States government increased the power and global reach of multinational corporations. The most controversial of these agreements, the North American Free Trade Agreement (NAFTA), made it easier for U.S. companies to buy low cost goods from Mexico, which were often produced by U.S. subsidiaries that migrated to take advantage of low-cost labor. Organized labor and most liberal Democrats opposed NAFTA because
Optical Powers: Telescopes and Imaging
Many astronomy curricula tap young people's natural curiosity about the universe. Generating interest in astronomical images is not a problem. The challenge is providing an approach that engages students in scientific thinking and analysis of images that leads to an understanding of the technology of telescopes, optical systems, and imaging cameras. Our effort has been to find a way for teachers with only minimal experience in this area to guide their students efficiently through the maze of
Digital Storytelling Multimedia Archive
Digital stories are multimedia-authoring projects combining texts, images, and audio files into a short film clip (mostly 3-5 minutes). In recent years, digital storytelling has turned college and university classrooms into spaces of creative critical production. Digital stories have proven to be a powerful medium for students to represent a theoretically-informed understanding of texts and contexts in a form other than “traditional” writing. This multimedia archive on digital storytelli
eBird's goal is to maximize the utility and accessibility of the vast numbers of bird observations made each year by recreational and professional bird watchers. It is amassing one of the largest and fastest growing biodiversity data resources in existence. For example, in 2006, participants reported more than 4.3 million bird observations across North America. The observations of each participant join those of others in an international network of eBird users. eBird then shares these observati
Learning Interdisciplinarity: A Course Portfolio
Linkon's research focused on evaluating the effectiveness of her incremental learning assignments in an interdisciplinary course. She gathered a variety of kinds of evidence of students' learning, ranging from surveys and interviews to students' projects and her own reflections. The three-assignment incremental learning sequence worked well for most students. Linkon's analysis of their work showed a clear development of analytical complexity in their writing over the course of the term. Students
Peer Review of Teaching - Course Portfolio
In this course portfolio, Dan Bernstein reports on changes he has made over three semesters in a psychology course on learning. He has succeeded in getting more students to achieve higher levels of understanding by changing the assessment from short abstract essay questions to problems that asked students to apply concepts in new contexts, and providing web-based opportunities for students to identify what makes some answers better than others. The portfolio includes examples of the assessments
Revealing Student Understanding in a Problem-Based Educational Psychology Course
This 'class anatomy' includes the full documentation of one of the problems on the application of a technique for teaching reading as well as some video excerpts from the class, and analyses of the development of students' understanding. It represents the first attempt of a Carnegie Scholar and KML staff to produce a multi-media website. This site was revised in 2004 to emphasize the multimedia components of Cerbin's work from an original course portfolio which is located at http://gallery.carne
CuraÁao is a computer program that simulates the sterile insect release method (SIRM) of pest population suppression, first conceived by E. F. Knipling (1955). The user can investigate the effects of several variables on the effectiveness of the method and discover what happens when some of the basic assumptions of the model are relaxed or violated in some way. The user should gain some understanding of the sorts of things that complicate the application of the technique in situations that are
Environmental Decision Making
Using the Extend 'connect-the-components' visual programming, students can model and simulate ecosystems including social and economic forces as well as study parameter variations to develop an understanding of ecosystem function and productivity. By making 'what if...' changes in the model, the effects of various proposed decisions about the environment can then be shown. EDM includes three ecological systems: Ponds, Grasslands, and Logging. Students can predict results of changes in the mode
