A Powerful Learning Platform for your Course

Expert TA is an online homework system equipped with a full suite of class management tools. Expert TA’s Introductory Physics resource is an independent and comprehensive library of questions designed to work with any text.

Expert TA has expanded its offering to provide a complete teaching solution for textbooks published by OpenStax. Each package provides access to the full eText, and an online homework platform containing end-of-chapter questions from the text as well as access to the supplemental “instructor test-bank” questions.

Question Authoring

Expert TA provides a powerful authoring tool to instructors and our broad range of question types allows for support of almost any subject. We have extensive libraries of questions that can be leveraged in Introductory Physics, Astronomy, Biology, and American Government and we are developing a number of new subjects currently. Instructors can easily create new original questions or copy any question from one of the main Expert TA libraries and modified as needed.

The Benefits of Textbook Independence

Expert TA’s textbook independent libraries provide instructors with flexibility from semester to semester that allows them the opportunity to change textbooks without having to switch their homework platform. Each library has been developed by a team of authors who both author original questions as well as supplement with enhanced versions of questions from OpenStax.

Enhanced OpenStax

Note: A surprising number of instructors use a textbook from a traditional publisher, but use the enhanced OpenStax online question collections via Expert TA for their homework, quizzes and exams.For these titles we have more than doubled the number of total questions available to assign. We also enhance each question as it is coded into our system by adding hints, feedback, and doing a full review and language polish. We also convert most of these questions into multi-step “scaffolded” questions and take full advantage of all of our engaging questions types.

Other OpenStax Titles

Coming in Fall 2026 – Online Homework for All OpenStax Titles: In mid-2024, Expert TA began a major initiative to expand our subject offerings. Almost two years later, we are about to release computer graded assessment collections for essentially all* OpenStax titles. What to expect in the collections: a) automatically graded versions for the vast majority of end-of-chapter questions from the texts, and b) additional original questions to supplement those. The majority of these questions will be implemented in the more engaging question type forms of drag-and-drop sorting, ranking, matching and in other compelling forms like graded simulations and “click on an image” questions.
