AMSER: Applied Math and Science Education Repository Abstract:

The SOCR philosophy has four parts: "1. Tools must be freely available on the Web (SOCR Motto: It˘ď‹ď_s online, therefore it exists!) 2. Newly developed materials must be useful, extensible, factually correct, validated and deployed on the web. 3. Tools must be well designed, extensible, platform-independent and open-source; 4. Materials must explicitly utilize some SOCR interactive resources (e.g., activities with applet demos) and provide the means of cross reference by various SOCR tools (e.g., applet calculations citing formulas in instructional materials)." Each section of the site consists of an instructional applet with many customizable settings, and three sections are worth noting. First, Interactive Distributions provides graphical illustrations of over 30 different statistical data distributions. An especially useful feature of this applet is the Info button -- when pressed, it takes the user to a detailed description of the selected distribution. The second section allows the user to perform a variety of statistical analyses on pre-defined or manually input data. These include analysis of variance (ANOVA), regression and correlation, and more. The third section is a modeler for a user-defined function. The user can draw a curve and the applet will fit a trend line to the curve. A serious shortcoming of this site is the lack of documentation provided with certain applets; while this is not an issue with the aforementioned sections, it makes the two remaining sections nearly unusable.

NSDL Staff Abstract:

The Statistics Online Computational Resource (SOCR) is a collection of downloadable applets, computational and graphing tools, and instructional materials for use in online data analysis, visualization, and integration. The tools are organized into categories by use: distributions (interactive graphs and calculators); experiments (computer-generated analogs of popular games and processes); analyses (tools for statistical data analysis); games (interfaces and simulations to real-life processes); data modelers (tools for distribution, polynomial and spectral model-fitting and simulation); and graphs, plots, and charts (comprehensive web-based tools for exploratory data analysis). There is also a collaborative collection (Wiki) of activities and educational materials that use these tools.

Internet Scout Project Abstract:

Teaching statistics can be a stochastic nightmare, but all of those dark clouds will part as users make their way through the fine resources offered on this site. The Statistics Online Computational Resource (SOCR) is based at UCLA, and their site includes online aids for probability and statistics education, including such handy tools as interactive applets, computational and graphing tools, and classroom activities. Teachers and those with a bent towards the world of statistics can look through the "Interactive SOCR Tools" area for items to use in their classes. The "Games" area includes an interactive scatterplot, along with a few other extras. Visitors will also appreciate their in-house wiki, which includes their latest educational offerings, such as free online datasets and even a curriculum for an AP statistics course.
