What is the difference between the topic text links and the open textbooks?

Some of the primary differences between the “open textbook” PDF files and the HTML “texts” are:

HTML texts  - include interactive features

• organized by individual topic
• include pop-up glossary terms
• include show/hide problems
• includes manipulatives

Open textbook PDFs - static, no interaction

• organized by unit
• include a Table of Contents at the beginning
• include objective identification throughout the content
• includes a ‘unit recap’ and glossary at the end of each unit
• the show/hide problems are identified as ‘self check’ with the answers at the end of each topic
