CK-12 FlexBook 2.0 vs mozaik3D

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.

mozaik3D is an educational app for exploring more than 1,300 interactive 3D scenes across school subjects. It is designed mainly for students aged 8 to 18. Learners can rotate and enlarge scenes or view them from preset angles; most scenes include narration, animation, captions, and quizzes. Listed tools also include exercises, virtual reality, search and filtering, freehand drawing, and games. More than 110 scenes offer native VR through the Meta and Pico app stores, with additional scenes being added. A free mozaWeb account allows access to five 3D scenes or educational videos and five educational tools or games each week. The Mozaik STUDENT subscription provides unlimited access to scenes, videos, media library items, tools, and games, plus mozaBook use and the ability to connect to a teacher's mozaBook. A licence works across multiple devices, but only one device can be logged in at a time. The free account costs nothing; the STUDENT list price is €36 a year, or €26 a year per student for packs of at least 30. Web scenes require installing a listed player.
