The Global Education and Learning Community welcomes more great projects. This time we have big integer software, a digital logic simulator, ad a problem-based learning simulator.

Take a look at these great new projects and join them if you can help them out.

BigAI

A free program for calculating really big numbers

BigAl is a command line tool, it is written entirely in Java. With BigAl, you can calculate really BIG numbers, the only restriction is the power of your computer. Not only basic calculations are supported but also special functions like factorial, fibonacci, lucas-sequence, periods, fraction reducing, binomial coefficient calculation and many more.

Pibel - a powerful Learning Management System using Problem-based learning (PBL)

Problem-based learning (PBL) has recently been introduced into the curricula of many universities and medical schools throughout the world. It is an active way of learning in which students are initially presented with a problem. Then, it is the realization of what they know and don't know about the problem that drives the learning process.

In the PBL setting, students are usually divided into small groups and presented with the problem in a progressive way. This method demands, and at the same time has the potential to develop, problem solving skills and learner independence.

Pure object-oriented design for digital circuit simulation

This project is a circuit simulator using object oriented techniques, The first multi-threaded implementation released and tested for moderately large circuits. Although there could be rooms for improvements on efficiency, the package should be readily useful for everyone.

The single threaded version is up and running - feel free to use / test them out. Current available components:
Buffer, NOT, AND, NAND, OR, NOR, XOR, XNOR, D-Latch, D-Flip-Flop. Any other recommended components would be appreciated.

This another Brazilian project and is used to publish the Pernambuco's Annals

From a new e-learning system to a simulation on digital logic, we are again happy to welcome new projects into The Global Education and Learning Community. This time we have
