BU mechanical engineering professor Lorena Barba has used several new technologies to transform the classroom experience, integrating iTunes, digital inking, screen casting, and blogging. Her classes often “flip” the classroom – that is, they deliver course content outside of class and refocus in-classroom time on discussion and activity – and allow a blended learning experience, where discussion and activity also happens on the Internet as well as in class.
Using a USB connected graphical tablet and her laptop, Barba was able to annotate her Keynote & Powerpoint slides to derive, in real time, solutions to complex mathematical operations. Further, using a screen capture application and a simple microphone, she recorded the lectures which were then posted for download through iTunes. Lectures for Fluid Mechanics (ME303), Bio-aerial Locomotion (EK131/132), and Computation Fluid Dynamics (ME702) can be subscribed to and downloaded from Boston University’s iTunes U page via iTunes or the iTunes U mobile app. Barba’s innovative courses were recognized among the Top 30 iTunes U Engineering Courses by the Degree Central (2010). Some of her courses have student blogs that allow dialogue about the course materials, screencasts, and Skype interviews.
At the First Annual Instructional Innovation Conference, Barba presented a paper describing the technology and techniques used for Digital Inking and Lecture Screencasts, which can be watched via screencast on YouTube. More information about Barba can be found via her people site, her research group, and at the BU:ENG-Mechanical Engineering website.
