- 2. Humanities Three Principal Aspects of how the LibreTexts is used The LibreTexts as a Curated Repository of “living” Content – largest on the net The LibreTexts as a Construction and Dissemination Platform – 100s of course The LibreTexts as Student Assessment/Performance Tool – 60M students annually
- 3. Humanities The Textbook Problem #1: Costs, inflexibility, & wasted effort The amount that students are spending on books and supplies topped out at $1,200 this year, according to the College Board. That’s equivalent to 14% percent of tuition at a four-year, public college – and 39% percent of tuition at community college. CHART by www.aei-ideas.org Data by WashPIRG

Humanities The Textbook Problem #2: Textbooks can be limiting, not empowering Textbooks should be tool to aid in the building of a robust knowledge base in students Textbooks should not be a crutch to limit content development, pedagogy, assessment and advancement Public Domain CC BY SA 4.0; PageMaker787 @ Wikicommons

Humanities The Textbook Problem #3: Textbooks hinder Education Advances Textbook publishers operate as de facto “gatekeepers” that hinders the modernization of education separating (wide-spread) students from SOTL researchers.

- 8. Humanities DOEd RFP Issued July 29, 2018 Proposals due August 29, 2018 Award to LibreTexts announced October 1, 2018 • Absolute Priority 1—Improving Collaboration and Dissemination Through Consortia Arrangements. • • Absolute Priority 2—Addressing Gaps in the Open Textbook Marketplace and Bringing Solutions to Scale. • Absolute Priority 3—Promoting Degree Completion. • Competitive Preference Priority— Using Technology-Based Strategies for Personalized Learning and Continuous Improvement
- 9. Humanities Very Short upshot of Proposal • Libretexts is a community effort • All are welcome to join • Libretexts is a construction/dissemination/usage platform with all you expect (or will expect) • Content integrated into LibreTexts has the same formatting allowing fast and easy remixing into textbooks and other OER • LibreTexts will work with any faculty, campus or OER team to move forward together

- 11. Humanities LibreTexts Teams The proposal called for five teams • Content creation • Content harvesting • Dissemination and outreach • Technology development and implementation • Assessment and analysis

- 13. Humanities • Ease of dissemination • Seamlessly integrates content over multiple sub-fields or across different fields • Facilitates highly-collaborative and highly-distributed construction efforts • Provides a mechanism for more advanced features than a PDF or paper-based book Online Homework system (adaptive) • 3D capabilities • Multimedia including videos and simulations • Numerical calculations infrastructure • Student tracking and assessment • Integrated annotation infrastructure Why Online? We focus on building an integrated online platform.

Textmaps are complemented by the modules in the Core. Textmaps
