R2D2: A model for using technology in education

The Cyber Security Education Consortium has more than 1,200 students.

The R2D2 learning model helps instructors accommodate diverse learning styles.

(Editor’s note: This article was written with college-level instructors in mind, but it’s just as applicable to secondary-school classrooms.)

“We’re doomed.” –C3PO to R2-D2

Frustrated. Challenged. Excited. Passionate. Overwhelmed. Opportunities. Waiting. These are the things I hear when I ask college professors around the world for two or three words to describe the use of web technologies in their classes. It does not matter if I am in Thailand, Taiwan, or Transylvania: I hear the same words. Many view technology as simultaneously a transformative tool for teaching and learning and one that should be avoided where possible. That is not surprising, given the barrage of new technologies to consider since the start of the millennium–including wikibooks, podcasting, Twitter, Second Life, digital books, open educational resources, shared online video, Facebook, and much more.

During the past two decades, I have designed several models and frameworks to help college professors sort through their options. The Read, Reflect, Display, and Do (R2D2) model is one such framework. While some look at it as a learning-style model, it is intended as a problem-solving wheel that represents phases of learning–from reading and exploration, to reflective writing, to visualization of the content learned, to attempts to try it out. R2D2 is also a means to help instructors consider diverse learner needs. At its core, it is also a tool for reflecting on one’s teaching practices. The four phases are described below.

Phase One: Read

The web contains countless resources for reading, researching, and listening. You can have your students discover and read online articles from open-access journals, expert web sites, or online portals of famous scientists like Albert Einstein, Jane Goodall, or Charles Darwin or writers like William Shakespeare, Jane Austen, or Edgar Allan Poe. There are tens of millions of online documents to read, discuss, debate, juxtapose, connect, compare and contrast, and perhaps turn into something totally different. Your students might also download and read scores of free eBooks made available by Google, the Internet Archive,, Bookyards, and others. Instead of reading from experts, students also might listen to podcasts that relate to course content. Some professors are currently pushing the edges of the risk continuum in this phase of the R2D2 model by using Twitter as a teaching tool. For example, students might be assigned to track the activities of a world-famous person who tweets.

Phase Two: Reflect

A natural next step is for students to blog about the concepts or ideas that they learned from their reading or listening activities. Such blogging might be done individually or in teams. Critical friends within the class or experts outside it might provide feedback on their blog posts. Your students might also read or track the blog posts of experts that relate to the topic of a class or program of studies. To push beyond the instructor as the sole source of knowledge, they might watch and reflect upon keynote speeches and the teachings of other participants from online conferences. Your students might also reflect on cases or scenarios that are posted online.

Phase Three: Display

The third phase involves pictures, timelines, flow charts, diagrams, and films. Such resources can now be found online in nearly any discipline. There are timelines of U.S. presidents, flash animations of cash flow principles, simulations of chemistry experiments, or stunning overviews of statistical procedures. Pubcasts from SciVee bring your students into the world of scientists. They can see and hear from the people who wrote the articles they have read. Shared online videos posted to YouTube, TeacherTube,, Link TV, CNN Video, Google Videos, NASA TV, TV Lesson, and other such places provide tremendous video content to help clarify or explain key course concepts or principles in visual ways.
