OpenEd - OpenEd Catalog

The OpenEd Catalog is built by deep semantic crawling of Internet-based educational resources and hosting sites; it imports extensive metadata on each resource (videos, games, exercises and other content) determining their creator, subject area, duration, quality, and grade level. The resulting catalog of resources is then aligned to standards probabilistically via machine learning. The results are then curated and validated through professional educators and then posted live on OpenEd.

OpenEd - Technology

The OpenEd site consists of several components, working together to help teachers find resources for their class and the standards they might be teaching.

OpenEd - History

OpenEd was founded in August 2012, with the purpose of providing a catalog of educational resources and aligning them to Common Core and other standards. The OpenEd cataloging process is not consistent with the current industry standard of crowdsourcing and curating individually, rather OpenEd has implemented the use of algorithms for automated alignment of resources combined with professional educator curators to validate those alignments. The process allows for a bigger scale of aligned content. At present moment the site contains over 750,000 resources, most of them aligned to the Common Core.


OpenEd is an online catalog of educational assessments, homework assignments, videos, games and lesson plans aligned to every Common Core standard and several other standards, and includes the only open source formative item bank. The site offers the ability for teachers to assign resources to their students online, letting students take assessments, do homework etc on their own computers or tablets. Assignments done online are graded automatically and presented to the teacher in a mastery chart. OpenEd's slogan mentions "assessment to instruction" meaning, formative assessments given on OpenEd can access OpenEd's large catalog on a per student basis to recommend the right resource to each student individually. The company has stated that functionality of searching the site and most of its resources are free and will continue to be free going forward. However, the company is also distributing premium content from publishers such as Pearson and Houghton Mifflin Harcourt to teachers for $9.95 per month.

OpenEd - History

The site also initially launched with the goal of providing materials cataloged to Common Core and later expanded to include other standards, such as Next Generation Science Standards and Texas Essential Knowledge and Skills. OpenEd is continuing to add other standards across the USA and internationally. In May 2015, the company changed its domain name from www.opened.io to www.opened.com.

Denishawn school - Schools opened

The first school that St. Denis and Shawn opened as partners was an older Spanish-style mansion in the hills of Los Angeles on St. Paul Street. It had an indoor room that was perfectly sized to fit smaller classes, a swimming pool and a tennis court for additional endurance training and/or leisure time, and the estate was filled with eucalyptus trees. Once they settled in, they built their own dancing platform over the tennis court. They also strategically built canopies over the outside space so that they could use it year-round.

Dead Eyes Opened - Background

Initially, Since the Accident was a cassette tape recorded between 1982 and 1983, and "Dead Eyes Opened" was only left on said tape to help fill up the blank space. The song includes a spoken word sample, which was credited by Tom Ellard in 2006 to be Edgar Lustgarten in the television series Scales of Justice. Lustgarten is the narrator, but the sample is from the episode Death on the Crumbles from the earlier BBC radio series of the same name. The show was based on the 1924 murder of Emily Kaye.
