Classroom Networks & Digital Textbooks

Work studies on networked digital textbooks, formative assessment, and adaptive learning



This page includes various work I produced while a in a Product Strategy Role at Texas Instruments between 2010-2012. This is an extension of my prior work on the TI-Navigator Classroom Network for graphing calculators; pivoting emphasis to tablet based apps and digital math textbooks paired with a teacher desktop software.

Role & Contribution

Senior UX Designer, Product Strategy

In this role, my responsibilities included producing concepts for future products and services. These designs explored how networked digital textbooks and other formative assessment tools could be used in the emerging tablet market.


In the early 2000s, TI introduced a classroom network system that allowed teachers to send quizzes and tests to students for completion on their graphing calculators. Results could be aggregated and added to a gradebook from the teacher's laptop computer. Functionality was later added to allow for students to participate in polling and collaborative classroom activities.

Although the system could be engaging, it required new hardware, software, and suffered from a complicated setup process that some users found too troublesome for everyday usage.

With growing adoption of iPads in the classroom, I was tasked with exploring what a classroom network could look like with tablet clients rather than graphing calculators.

Networked Digital Textbooks

Traditional textbooks typically introduce concepts with examples and practice questions. Instructional technology (such as graphing calculators) are often used as standalone tools that help reinforce or explore the lesson, and a separate quiz or test is used to measure student understanding. This process can be quite inefficient and requires a fair amount of task switching where intructional time is spent on adminsistrative tasks, and in many cases, the teacher is not aware of the class understanding until quizzes and tests are administered and graded.

Although digital textbooks were not new, they mostly represented 1:1 digital copies of their hardcover counterparts. While there were some inherent advantages to this, their usage in the classroom still basically followed the existing pattern (concept introduction, practice / exploration, assessment). For these concepts, I wanted to illustrate how a truly interactive digital textbook could streamline the process - providing the concepts, exploratory tools, and formative assessment into a networked experience.

Even after leaving the Educational Technology market in 2013, I still get excited about the possibilities of a networked digital textbook. While this was a great project to work on, I am not sure that it would have been considered as a viable product offering due to how much it diverged from the core business. In any case, it was a fun exercise and I am glad I was given an opportunity to work through these ideas!
