## Open-Source Textbooks, Software, and Resources

- MySFA
- SFA A-Z
*CoCalc*, a collaborative environment for doing mathematics by W. Stein.- My open source textbooks
*Abstract Algebra: Theory and Applications*and*The Ordinary Differential Equations Project*have a new home at judsonbooks.org. - Open Textbook Initiative. The The American Institute of Mathematics (AIM) has developed evaluation criteria to identify the open source textbooks that are suitable for use in traditional university courses. The Editorial Board maintains a list of approved textbooks which have been judged to meet these criteria.
- UTMOST: Undergraduate Teaching in Mathematics with Open Software and Textbooks. The UTMOST project is an NSF IUSE grant focusing how students understand and faculty actually use textbooks in undergraduate mathematics courses. UTMOST will use this understanding to produce textbooks that are more effective in promoting student learning. The major components of the project involve education research, resource development, dissemination, and evaluation.
- UTMOST Sage Cell Repository. The Sage cell repository is a highly structured catalog of reusable Sage cells that can be easily embedded into online documents. Each Sage cell is tagged with important attributes to make it easy for instructors, authors, and anyone using Sage to find examples of Sage code appropriate for their needs. Below is an example of a Sage cell that plots a sine curve.

- PreTeXt is a lightweight XML application for authors of scientific articles, textbooks and monographs that incorporates the best of DocBook, LaTeX, and HTML. When a document is written in PreTeXt, it is possible to quickly produce print, PDF, web, HTML, Sage Notebooks, Jupyter Notebooks, and even Braille from a single source.
*Logic and Proof for Teachers*, an open source textbook by Lesa L. Beverly, K.M. Childs, T. W. Judson, and D. A. Pace available in PDF format and online.*A First Course in linear Algebra*, an open source textbook by R. Beezer.*Sage*, open source mathematics software founded by W. Stein.- ODE Reviews. Reviews of articles relating to the teaching and learning of ODEs.
- The CODEE Journal. The CODEE Journal is a peer-reviewed, open-access publication, distributed by the CODEE (Community of Ordinary Differential Equations Educators) and published by the Claremont Colleges Library, for original materials that promote the teaching and learning of ordinary differential equations.
- SIMIODE (Systemic Initiative for Modeling Investigations and Opportunities with Differential Equations). SIMIODE is a resource for faculty members and students who want to focus on compelling applications, modeling, motivation for studying differential equations, and instructional technologies and make investigation of realistic scenarios possible. SIMIODE provides a comprehensive and cohesive community approach to studying differential equations.
