In their own words
CK-12 FlexBook 2.0
CK-12 FlexBook 2.0 provides customizable digital textbooks for K–12 subjects including science, math, and social studies. Lessons can combine text with PLIX interactives, simulations, adaptive practice, and related learning materials. Adaptive Practice draws questions from a library of more than 150,000 and adjusts selections based on student answers. Teachers can assign lessons, videos, interactives, and practice to whole classes or differentiated groups, then view progress reports. Educators can reorder chapters and edit or add content in customized FlexBooks. The service works in browsers on laptops, desktops, Chromebooks, tablets, and mobile devices, and is listed at free. Standalone Simulations and PLIX Interactives require a tablet-size screen or larger. Users may download PDFs of FlexBooks they create or customize, though interactive content may not render; CK-12-created PDFs are not downloadable. CK-12 says it is still converting all core content to FlexBook 2.0. Listed SSO or LMS partners include Google Classroom, Canvas, Schoology, Kiddom, Clever, and ClassLink.
OpenLearn
OpenLearn is a free web learning platform delivered by The Open University. It offers courses, articles, quizzes, interactive games, videos and audio across many subjects, with short courses described as taking 1 to 24 hours. The listed Free courses plan includes nearly 1,000 courses at free. After completion, learners can download a free Statement of Participation, and some courses award a digital badge. OpenLearn courses do not carry formal credit toward a qualification. A free account enables enrolment, progress tracking and activity-record downloads; general content is available without an account, though users must be at least 13 to create one. Materials can be shared through other learning systems in IMS Common Cartridge, HTML and Moodle formats. OpenLearn says its software tools are open source and its main learning environments use Moodle and Drupal. The site reports partial WCAG 2.2 AA compliance, with issues in some legacy images and interactive activities. It was founded in 2006 and is based at Walton Hall, Milton Keynes.
