USGS Bedform Sedimentology
This site presents a collection of photographs, short movies, classifications, and computer-generated images for identifying various types of bedforms. Viewing of movies and 3D dynamic computer-modeled bedforms allows students to observe the creation, internal structure, and migration of bedforms through time. Photographs depict these processes in the real world. In addition, software for simulating ripple and dune bedforms and crossbedding is available for a free download. The site also feature
National Atlas of the United States
This is a primary source of U.S. maps and geographic information. Zoom in on your state and make your own map by selecting features to display: cities and counties, roads and rivers, population and 109th congressional districts, crops and livestock, amphibians and butterflies, air and water quality, earthquakes and land cover, forest types, and more. Print a U.S. map (with or without names of states and capitals). Find an aerial photo of your neighborhood.
Cell Differentials offers a visual dataset of white blood cells that gives students practice in developing strategies and techniques for the recognition of these blood cell types. Over 100 different cell images are randomly presented with feedback on successful identification. In traditional labs, the recognition of white blood cell types can be compromised by several factors. Developmental changes can make recognition difficult and some cell types exhibit similar features. Microscopy can be a
Activities for children to learn about weather and tools for teachers and parents to help them explain the different types of weather to children.
When I started teaching this subject I found three kinds of texts. There were applications books that avoid proofs and cover the linear algebra only as needed for their applications. There were advanced books that assume that students can understand their elegant proofs and know how to answer the homework questions having seen only one or two examples. And, there were books that spend a good part of the semester multiplying matrices and computing determinants and then suddenly change level to wo
Lecture on fieldwork in the Soviet Union, 1988-9
Public lecture given in October 1989 by Professor Ernest Gellner. He reflected on his year spent in the Soviet Union on the eve of the collapse of communism.,The lecture was given to a Cambridge Audience in the Rayleigh Lecture theatre in the Social and Political Sciences Faculty. Professor Gellner had flown in that morning from America. It was filmed, using a video 8 camera, by Humphrey Hinton. It was chaired by Dr. Alan Macfarlane. The video is unedited. The lecture lasts for about 65 minutes.
Patient Communication Skills, 2009
The materials on this page represent a curriculum for teaching effective patient communication to dentistry students. These techniques could be useful for other healthcare providers, as well: medical students, nursing students, public health providers, and in-practice health care providers. There are two main types of resources: performance keys and videos. Performance Keys are text documents that articulate key patient interaction skills, and give examples of more and less effective techniques
Object of History
The Object of History is a cooperative project between the Smithsonian’s National Museum of American History and George Mason University’s Center for History and New Media. The project was conceived of in an effort to find a low cost way for students and teacher of U.S. History to have access to the museum’s collections and the expertise of the curators. As a result the materials on the site are designed to improve students’ content knowledge of standard topics in U.S. History and to imp
Essential Science for Teachers: Earth and Space Science
In-depth interviews with children that uncover their ideas about the topic at hand.,The interviewer shows the student two different representations of mountains, one smooth and one jagged, and asks her to describe what she sees. As she describes a volcano, the interviewer probes to find out why she thinks it is a volcano, whether a volcano is a mountain, and how a volcano forms a mountain.
Essential Science for Teachers: Earth and Space Science
In-depth interviews with children that uncover their ideas about the topic at hand.,In this segment the interviewer is trying to find out if the student has prior knowledge about types of rocks by asking her about the stripes on the rock and why she thinks it is striped. She uses the word "metamorphic" and goes on to explain what a metamorphic rock is. The interviewer probes further by asking her why rocks get pressed together and where the stripes may have come from. He then shows her a picture
Whippo Problem Space
What! You haven't ever seen a Whippo? What about a Whammel? Well, how do you think that whales evolved? Which mammals do you think are their closest living relatives? Trying to make sense of whale evolution is a great place to engage in some evolutionary reasoning and look closely at the way scientists work through difficult historical problems. By the way, the term Whippo is used as a sort of shorthand for the hypothesis that whale and hippos represent sister groups—that is, they are each oth
Consonant Digraphs: sh, ch, wh, th (Mr. H and His Four Girlfriends)
This is an amusing teacher-created story from 40 years ago to help
first-grade students remember the sounds represented by the consonant digraphs sh, ch, wh, and th.
Study of Place: Antarctic Exploration
Each two-week module in the Study of Place curriculum is framed by an historical event that makes a connection between the physical environment and human activity. The activities focus primarily on physical and earth science content, geography, and inquiry skills. Assessments and scoring rubrics, including a pre-assessment that can be used for both modules, are embedded in each module, providing opportunities for tracking student learning. The Antarctic Exploration module is framed by Sir Ernest
Analysis of a selection of educational ICT systems for mathematics
The deliverable describes a grid that has been designed to study ILEs (Iteractive Learning Environments) in arithmetic and algebra, a process for choosing 6 ILEs to be studied and the result of the studies. The studied ILES are: ActiveMath, AnimalWatch, Cognitive Tutor, Math-Teacher Plus, MatXpert, Ms. Lindquist.,deliverable D20.5.1 from ERT Telma in the NoE Kaleidscope
Analysing the significance of problem solving expertise and computational tool proficiency in design
This paper presents a pilot study to analyze the role of problem solving expertise (PSE) and computational tool proficiency (CTP) of expert and novice architects in the ideation process within a distributed cognition environment. To analyze PSE, we studied the frequency of occurrence of unique problem solving tasks per limited commitment mode (LCM) revisit. We also devised a quantitative measure for analyzing CTP based on the frequency of unique and normally distributed modeling activities per d

The Western Soundscape Archive (WSA)
The Western Soundscape Archive (WSA) recognizes the vital connection between places and their soundscapes and features audio recordings of animals and environments throughout the western United States. The WSA typically features three types of recordings: those of individual species, ambient soundscapes and interviews. The project's geographic focus includes eleven contiguous western states — Arizona, California, Colorado, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington and Wyomi
Thinking Like a Social Scientist: a lecture by Professor Saul Estrin
In this new series of lunchtime lectures, nine of LSE's most senior academics explain the latest thinking on how social scientists work to address the critical problems of the day. They survey the leading ideas and contributions made by their discipline, explain the types of problems that are addressed and the tools that are used, and explore the kinds of solutions proposed. Saul Estrin is head of the Department of Management at LSE.
