Open Source Computer Aided Instruction (CAI) Software

Over 1,000,000 page views per month. Jmol/JSmol is a molecular viewer for 3D chemical structures that runs in four independent modes: an HTML5-only web application utilizing jQuery, a Java applet, a stand-alone Java program (Jmol.jar), and a "headless" server-side component (JmolData.jar). Jmol can read many file types, including PDB, CIF, SDF, MOL, PyMOL PSE files, and Spartan files, as well as output from Gaussian, GAMESS, MOPAC, VASP, CRYSTAL, CASTEP, QuantumEspresso, VMD, and many other quantum chemistry programs. Files can be transferred directly from several databases, including RCSB, EDS, NCI, PubChem, and MaterialsProject. Multiple files can be loaded and compared. A rich scripting language and a well-developed web API allow easy customization of the user interface. Features include interactive animation and linear morphing. Jmol interfaces well with JSpecView for spectroscopy, JSME for 2D->3D conversion, POV-Ray for images, and CAD programs for 3D printing (VRML export).

EduMIPS64 (aka edumips) is a cross-platform MIPS 64 ISA simulator. It can be used to run and debug MIPS programs that are written using the MIPS64 instruction set. It supports visual debugging and lets you see what instructions do in the pipeline.

JMCAD is an program for the modeling and simulation of complex dynamic systems. This includes the ability to construct and simulate block diagrams. The visual block diagram interface offers a simple method for constructing, modifying and maintaining complex system models. The simulation engine provides fast and accurate solutions for linear, nonlinear, continuous time, discrete time, time varying and hybrid system designs. With JMCAD, users can quickly develop software or "virtual" prototypes of systems or processes to demonstrate their behavior prior to building physical prototypes. The user builds his system model by selecting predefined blocks from a block library and simply wiring the blocks together. Each block of the diagram performs a function. Users can also create custom blocks in Java and add them to the JMCAD block library. JMCAD is a block diagram language for creating complex nonlinear dynamic systems.

Myrtle is a simple programmable spreadsheet and statistical analysis software specifically designed for learning statistics. It provides the standard spreadsheet functionality one would expect like multiple tabbed sheets, relative and absolute row and column referencing in formulas, and a large catalog of built-in functions. Functions specific to logic and computer science, mathematics, probability, and statistics are available. Student's can easily create, customize, and update plots and graphical summaries of their analyses. Myrtle offers a unique bookmarking facility which allows students to create and reuse named references to their favorite cell ranges. This can help students focus attention on the important relationships among particular rows or columns of data. Myrtle's graphics and reporting features allow students to report back to their instructors their mastery of course content.

Argunet is a client-server software for computer-supported argument visualization (CSAV). Reconstructed debates are visualized as argument maps and can be shared through the Argunet Server.

GoGraph is a tutorial software giving informatics students an easy, interactive and ergonomic way to learn and exercise the graph theory. It is based on JGraph, an open-source graph component for Java.

IMathAS is a web-based math assessment and homework system. It is a course/learning management system (CMS/LMS/VLE) and testing system featuring algorithmic questions, similar to WebWork, Webassign, and publisher systems like iLrn, MathXL, etc.

JBioFramework (JBF) is a set of two different chemical separations simulations (2D Electrophoresis and Mass Spectrometry) that are frequently used in chemistry, biochemistry and proteomics research. It is written in the Java programming language and will run on any and all systems that have the JVM installed. As we continue to develop the software over the coming months/years and attempt to quantify the success of our efforts with testing and reviews, user input is very important. Please don't hesitate to review the software below or email Paul Craig [pac8612@rit.edu] with larger descriptions/bugs/feature ideas. Our next scheduled release will contain (in addition to 2DE and MassSpec) a 1D Electrophoresis simulation as well as a tab containing ChemAxon's MarvinSketch [http://www.chemaxon.com/products/marvin/] along with some improved functionality. It should be out shortly as we complete the creation and modification of a permanent domain for the project.
