Beginning and Intermediate Algebra , by Tyler Wallace is licensed under a Creative Commons Attribution 3.0 Unported License. The course was originally created for the Open Course Library project, funded by the Bill and Melinda Gates Foundation and managed by the Washington State Board of Community and Technical Colleges. The text is designed for two terms, and is most appropriate for face to face settings. This text is fully integrated with our online learning system, Lumen OHM. The source files for this text are written with TexMacs, should you wish to edit them, otherwise the fully integrated course contains pdfs for each chapter.Topic Overview

Online Content
Each module of the fully integrated Lumen OHM course contains two kinds of assessments:- Video Lessons: These assessments contain video lessons. After each video there are two questions that correspond with the examples in the video. These assessments are intended as learning materials. Optionally, there are workbooks available to guide students in taking notes on the videos.
- Practice: These assessments contain additional problems beyond the types covered in the video lessons. These assessments are intended to serve the role of homework. Video help is turned off on these assignments so students have to practice without video help.

Many questions in the Lumen OHM libraries are randomized, algorithmic questions. Students get immediate feedback after they submit an answer. Question types include:- Entering an integer, fraction, decimal
- Graphing
- Reading information from a graph
- Multiple choice
- Free-writing (instructor graded)
