http://www.causeweb.org/cwis/index.php?P=FullRecord&ResourceId=2325
http://www.causeweb.org/cwis/index.php?P=FullRecord&ResourceId=2325Calibrated Peer Review (CPR) is a program, for networked computers, that enables frequent writing assignments without any increase in instructor work. In fact, CPR can reduce the time an instructor now spends reading and assessing student writing. CPR offers instructors the choice of creating their own writing assignments or using the rapidly expanding assignment library. If you believe in constructivist learning, writing is the most important tool that you have. But if you have a class of 300 students, grading essays challenges even the true believer. Calibrated Peer Review (CPR)can be used in classes of any size. CPR is based on the model of peer review in science. The student reads a document, either on-line or hard copy, then writes about it. When the student has demonstrated competence as a reviewer, the program delivers three peer documents on for review. The student answers content and style questions and assigns scores. Finally, the student does a self-review. The student grade comes from writing and reviewing. Even though the program is only in its third year, approximately 100,000 students have used it. Although CPR was designed for use in large chemistry classes, experience has shown that it can serve in many other disciplines, as well. Currently, business, chemistry, economics, English, and life science instructors are using CPR in college, graduate and professional, high schools and middle schools. CPR was developed in the Chemistry Department at U.C.L.A. with funding provided by the National Science Foundation and Howard Hughes Medical Institute.Mon, 16 May 2011 02:11:16 -0400**Power Tutorial

WISE Power Tutorial can be used in a variety of settings including as a tutorial for an individual student, during a lab, and after a lecture. The applet embedded in the tutorial could be used during an in-class demonstration.Sun, 30 Jan 2011 01:36:32 -0500**Statistics Online Computational Resource (SOCR) Modeler

http://www.causeweb.org/cwis/index.php?P=FullRecord&ResourceId=2099In this module, students can test their knowledge of levels of measurement by attempting to determine the the level of measurement of ten different variables. For each variable, a statement is also provided and students can indicate whether the statement about the variable is valid or invalid (given the way in which the variable was measured). There is also a brief "refresher" included here about levels of measurement.Fri, 9 Jul 2010 02:37:04 -0400**Many Eyes

This site has an area for featured data sets and is constantly be updated by its users. In its About Us section Many Eyes proclaims that it "is a bet on the power of human visual intelligence to find patterns. Our goal is to "democratize" visualization and to enable a new social kind of data analysis. Jump right to our visualizations now, take a tour, or read on for a leisurely explanation of the project. " While its use is free Many Eyes does require "an alphaWorks Services Use Agreement" that spells our terms of use,copy right, liability, etc. Users must agree to terms and conditions.Wed, 16 Jun 2010 01:23:12 -0400**Stat2Labs

This material is designed to give students a sense of the importance and allure of statistics early in their college career. By incorporating many of the successful reforms of the introductory statistics course into a wide range of more advanced topics we hope that students in any discipline can realize the intellectual content and broad applicability of statistics."Wed, 28 Apr 2010 11:29:41 -0400Virtual Statistician
