Authentic Assessment in Mathematics Home Page The Geometry Forum Summer '94 Workshop at Swarthmore College, Swarthmore, PA. The goal of this project was to collect and organize available INTERNET resources on Authentic Mathematical Assessment applicable to Secondary Schools. What is it? Are there examples? Where can I find additional information? S-Lang Library Information Page S-Lang is a multi-platform programmer's library designed to allow a developer to create robust multi-platform software. It provides facilities required by interactive applications such as display/screen management, keyboard input, keymaps, and so on. The most exciting feature of the library is the slang interpreter that may be easily embedded into a program to make it extensible. While the emphasis has always been on the embedded nature of the interpreter, it may also be used in a stand-alone fashion through the use of slsh, which is part of the S-Lang distribution.

GNU Octave GNU Octave is a high-level interpreted language, primarily intended for numerical computations. It provides capabilities for the numerical solution of linear and nonlinear problems, and for performing other numerical experiments. It also provides extensive graphics capabilities for data visualization and manipulation. Octave is normally used through its interactive command line interface, but it can also be used to write non-interactive programs. The Octave language is quite similar to Matlab so that most programs are easily portable. Octave is distributed under the terms of the GNU General Public License.

Welcome to the Mathematics Assessment Project News New – TRU Math: Teaching for Robust Understanding of Mathematics is a suite of tools for professional develompent and research - the alpha versions of these documents are available here… More International Awards for Team: Hugh Burkhardt and Malcolm Swan, leaders of the Shell Centre team, have been chosen by the International Commission on Mathematical instruction (ICMI) as the first recipients of the Emma Castelnuovo Medal for Excellence in the Practice of Mathematics Education. This complements the award by ICMI to Alan Schoenfeld of the 2011 Felix Klein Medal for Lifetime Achievement in research. Read more… The project is working to design and develop well-engineered assessment tools to support US schools in implementing the Common Core State Standards for Mathematics.

Relational Relational an educational tool to provide a workspace for experimenting with relational algebra, an offshoot of first-order logic. It provides GUI that can be used for executing relational queries, and also provides a command line interface. Provides a standalone Python module that can be used for executing relational queries, parsing relational expressions and optimizing them. The UI now implements sessions and remembers where you left off the previous time. It was also redesigned to be able to fit smaller screens.

Free Mathematics Resources OnLine What about free graphing and algebra on your mobile phone? XCalc is a free Java Applet which offers a graphing calculator for any mobile phone which runs Java (which is nearly all of them now!) Think about the possibilities for classes that do not yet have access to graphing calculators! While limited (it does not yet have a trace facility) it DOES offer 2d and 3d graphing which is quite fast and powerful. Well worth a play! Now, combine that with quite a useful algebraic workpad that allows you to define variables and formulas and evaluate these.

Shift Shift is a programming language for describing dynamic networks of hybrid automata. Such systems consist of components which can be created, interconnected and destroyed as the system evolves. Components exhibit hybrid behavior, consisting of continuous-time phases separated by discrete-event transitions. Components may evolve independently, or they may interact through their inputs, outputs and exported events. The interaction network itself may evolve. We believe that the Shift model offers the proper level of abstraction for describing complex applications such as automated highway systems, air traffic control systems, robotic shopfloors, coordinated submarines and other systems whose operation cannot be captured easily by conventional models.

Factorization of Quadratic Expressions with Negative Coefficients ( Read ) What if you had a quadratic expression like or in which some or all the coefficients were negative? How could you factor that expression? After completing this Concept, you'll be able to factor quadratic expressions like these for various negative coefficient values.
