Need high-quality OER for your application or platform? We can help.


We employ teachers to harvest and curate only the best K-12 OER using a consistent process and time-tested rubric that ensures quality and usability for teaching and learning.

What are your unique OER curation requirements?


We have developed a rich set of metadata, applied by teacher curators, to each resource included in the OER Metadata Collection. This metadata well describes OER and enables highly customized integrations.

What OER metadata is critical for your application?


OER is dynamic – a benefit but also a challenge to manage for availability at the point of teaching and learning. We partner proprietary technology with teacher curator review to ensure both availability and appropriateness for the classrom.

Is OER availability important to your users’ experience?

OER Playlists by Academic Standard

In conversations across a broad spectrum of K-12 Districts and organizations that serve them, Knovation noticed teachers struggling to find quality, aligned resources for instruction. No longer will teachers sort and sift through an oversupply of content, curated or not. They are looking for very small, specifically curated collections of the best resources to address an academic standard. In response, Knovation's seasoned teacher curation specialists targeted the best resources aligned to Common Core State Standards (CCSS) for Math and English Language Arts, and the Next Generation Science Standards (NGSS). The result of this work is Knovation’s highly curated “Teacher Recommended” Playlists, tightly correlated for CCSS and NGSS.

What does “Teacher Recommended” resources mean?

Teacher Recommended resources are first evaluated using Knovation’s quality rubric to assure relevance, appropriateness, and value of the resources. Then, Knovation teacher curators review and hand select resources they know work in their classrooms and feel confident would work in other teachers’ classrooms that specifically align to the respective academic standard.

What else did Knovation’s teacher curators consider when recommending resources?

In curating this Collection, Knovation teacher curators considered different learning styles and the reasons why teachers use digital content. These teacher curators have done everything in their power to locate, evaluate, and align reliable content that is freely available and meets expectations of quality.

What can a teacher accessing resources in the Teacher Recommended Collections expect?

Teachers can expect the Teacher Recommended Collection to meet certain scale requirements – 6-10 digital resources per education standard. As well, resources in the Teacher Recommended Collection represent:

  1. A broad range of digital content publishers
  2. Diversity of learning resource types (video, audio, interactive media, etc.)
  3. Resources both for practice and instruction
  4. Resources that appropriately span complexity/readability ranges

Additionally, Knovation uses advanced technology to continuously monitor and maintain Teacher Recommended Collections resources giving teachers comfort that resources are available and appropriate at the point of instruction.
