Apps & Extensions

This page provides a link to apps and extensions that have been created by and for the Doceo Center for Innovation + Learning.

Doceo Center Trailblazer Extension

This extension allows you to contribute anonymous data to the Doceo Center regarding the web resources you use to provide metrics and suggestions for other users.

The goal of collecting this anonymous data is to provide researchers with an understanding of patterns of behavior across schools and regions. All data collected through this extension is anonymous, and researchers have no method for determining the source of specific pieces of data. This extension does not have any location or identity tracking ability.

All data collected in this manner is stored in a database within four tables: an anonymous user table, a history table, a url table, and a bookmark table.

Anonymous User Table


This table lists all of the anonymous users that are contributing data to the database. Each user is given a random, unique id (sid), which is stored on their computer and in the database. Whenever data is sent to the database, this id is used to tell the database where the data should be assigned. The profile cell is used to differentiate users (e.g., researchers, teachers, and students) and helps researchers to organize data in a way that is useful for analysis (e.g., by knowing which websites teachers visit, researchers can determine what websites have educational value). The dcuid cell is used to connect the sid to data in the history and bookmark tables.

History, URL, and Bookmark Tables


These tables store data on webpages visited and bookmarks created. Information that is stored about websites include the base url, page title, the last time the anonymous user visited the site, and how many times the anonymous user visited the site. This data uses the dcuid to connect it to the anonymous sid value in the user table.

Data Anonymity

Anonymity of data is essential to ensure user privacy. For this reason, researchers have taken great pains to ensure that collected data cannot be traced to a user. The only person who has the ability to see who an sid belongs to is the owner of that sid, and this can only be accomplished by the user looking for this information on his/her own computer. There is no record of which sid belongs to which computer in the database, and no other information (e.g., names, emails, ip addresses) is recorded that could be used to link activities to a person's identity, location, or school.

To understand this level of data anonymity, a hypothetical situation may be instructive. Let us assume that a user visits a particular website. Could someone with access to the database conceivably determine that person's identity? Since no identifying information is sent to or stored in the database (e.g., names, ip addresses, schools), the only identifier that the webpage visit could be linked to would be a randomly generated sid (e.g., "40e25ef878122e33bbd9aa2a3fea4d"). Since this sid is not connected to anyone in the database or in any records (other than on the user's own computer), it would not be possible to connect the sid to the person's identity, and anonymity is maintained.

Decisions to maintain anonymity were made, because researchers have no interest in understanding individual behavior patterns but only group dynamics. By making all user contributions anonymous, researchers are able to analyze patterns across groups and over time without knowing specifics about individuals.

Incognito Mode

If you would like to temporarily prevent the extension from collecting web history data, you may use Google Chrome's built-in Incognito mode. When enabled, the extension will ignore web history.

Doceo Center Common Core Explorer

This early alpha version allows you to navigate through the Common Core standards by grade level.
