OATutor 1.7

Version 1.7 includes expanded content coverage to new courses, including Calculus content specifically curated for UC Berkeley's MATH 1B Calculus Course. Additional content added to the existing content library includes lessons tailored to active deployments at other higher learning institutions using OATutor in the classroom.

Equivalent content to the OpenStax Calculus Content has also been added to the library in Swedish to support our first international classroom deployments. In addition to the content, a new framework has been developed for localization and UI language switching to supported languages (English, Spanish, Swedish) based on the selected textbook, modifying the UI elements to correspond accordingly with what is specified in the language locale file. The platform default language can be changed from the current English default in the config file, with the course language set to automatically override the default.

A completion based mode for lessons has also been added, with the lesson level toggle between mastery and completion as the enableCompletionMode meta tag for the coursePlans file. Instead of completing the lesson upon reaching a BKT-calculated mastery threshold, the lesson is finished when all problems in the lesson are exhausted.

This new version also includes significant upgrades to platform Cloud infrastructure, migrating a majority of the codebase to be hosted via an AWS backend integration. We have also transitioned to an Amazon cloud-based LTI support system for improved integration of the platform with Canvas courses.

Release also addresses various bug fixes, including the equation editor not correctly rendering for certain algebra problems and incorrect message popups appearing for students upon reaching completion and mastery stages.

Full Changelog: v1.6...v1.7

OATutor 1.6

This major version (1.6) adds UI language localization support and an LTI reliability improvement by porting the LTI middleware that the production system relies on to AWS Lambda.

This commit also rectifies a long standing bug in the BKT-based next item selection logic whereby a user could never master out of a multi-skill lesson. We have also updated the upper right “Mastery” label to “Lesson Mastery” which is the average mastery of all the skills in the lesson.

For flexibility, we also introduce a configuration to turn off A/B testing (for production environments). This option is set to off by default. Example adaptive next-item selection and BKT parameter A/B tests have been better described in the codebase.

Finally, content areas have also expanded to include OpenStax: Calculus Volume 1, equivalent to AP Calculus AB.
