It is not a numerical calculator; rather it visually and holistically demonstrates the relations among important concepts. Visual ANOVA is supported by online instructions and by an extensive online lecture explaining the theory behind the Analysis of Variance. The online lecture is supported by two types of assignments: 1) Online computer-graded homework, and 2) A pdf file that gives students the opportunity to do handwritten homework problems with answer keys. http://www.merlot.org/merlot/viewMaterial.htm?id=89373 The Utah online Virtual Lab is a JAVA program run dynamically off a database. Instructors author a statistical virtual reality simulating theories and data in a specific research focus area by defining independent, predictor, and dependent variables and the relations among them. Students work in an online virtual environment to discover the principles of this simulated reality: they go to a library, read theoretical overviews and scientific puzzles, and then go to a lab, design a study, collect and analyze data, and write a report. A student's design and data analysis decisions are computer-graded and recorded in a database; the written research report can be read by the instructor or by other students in peer groups simulating scientific conventions. http://www.merlot.org/merlot/viewMaterial.htm?id=89959 With so many claims about education products and practices, what does it mean to be "research-based" when it comes to knowledge of the brain? Whether you want to learn about brain-based teaching methods, help students improve reading and writing skills, or explore the possibilities brain research provides, the Education Connection of BrainConnection.com is for you. http://www.merlot.org/merlot/viewMaterial.htm?id=89228 Difference to Inference is an online JAVA program simulating theory testing and falsification through research design and data collection in a game format. The program, based on cognitive and epistemological principles, is designed to support the learning of thinking skills underlying deductive and inductive logic and statistical reasoning. Students must strategically plan a series of studies and then use the data from those studies to eliminate competing theories. Difference to Inference has database connectivity so that game scores can be counted as part of course grades. No other assignments are necessary. Difference to Inference is supported by an online tutorial for its use and by an online course lecture explaining the principles of scientific methodology behind its play. A companion game whose play fits extremely well with Difference to Inference (for teaching scientific methodology) is called "Detect Difference." Articles about Difference to Inference can be found in the May 2001 issue of Behavior Research Methods Instruments & Computers and in The Journal of Infomation Technology in Medicine (2000). http://www.merlot.org/merlot/viewMaterial.htm?id=89958 The United States participated along with 40 other nations in the Third International Mathematics and Science Study (TIMSS), a comparative achievement test of mathematics and science at the fourth, eighth, and twelfth grade levels. This site contains many resources for learning about and discussing TIMSS, including Attaining Excellence: A TIMSS Resource Kit, developed by the U.S. Department of Education. Additional materials and contact information will help educators, teacher educators, parents, and students understand and work with TIMSS data.
