CK-12 FlexBook 2.0 vs Nearpod

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.

Nearpod helps educators create and deliver interactive lessons, with options for live participation, student-paced work or front-of-class teaching. Teachers can build lessons from scratch or import PowerPoints, Google Slides, PDFs, videos and YouTube videos, then add formative assessments and media activities such as Draw It, Polls, Drag & Drop, VR Field Trips and PhET simulations. Its library contains more than 22,000 customizable, standards-aligned lessons, videos and activities, including K–12 content. Teachers can review real-time feedback and post-session reports to assess student understanding and work.
