Laura GuertinLaura Guertin at Penn State Brandywine uses podcasting and Google Earth in her earth and geoscience courses to help students grasp science principles. She has discovered that when students use these technologies, the quality of their science improves, they care more deeply about the subject matter, and they are eager to share their learning with a wider audience.

In 2005, Guertin began to record her classroom lectures in MP3 format. She makes them available to students via iTunes U , allowing them to engage in course content outside class.

Additionally, she recorded review sessions consisting of questions to help students prepare for exams. She asked them to listen to each question, pause, and try to answer it. Guertin explained, “These were fundamental questions to make sure they understood the basics, then during the test, I asked synthesis-type questions.” She said these recorded reviews are beneficial because Brandywine is a commuter campus and it is difficult to get the class together for face-to-face review. “This way,” Guertin said, “all the students had access to it.”

Now that Brandywine has a Digital Commons studio, Guertin assigns projects that ask the students to be the creators of podcasts and other digital media.

As one project in her Environment Earth course, students created an audio tour of tree species marked on a trail at Ridley Creek State Park. Each student recorded a podcast about a species, then added photos to it. Guertin said her students worked hard to create high-quality work. She observed, “They were not happy turning in something that wasn’t to their satisfaction. I think it’s because the projects they did are being viewed by an outside audience. I saw a sense of pride and professionalism in a way that I wouldn’t have gotten if I just had them write a paper. Their voice had this inflection to it because they were excited to talk about the tree. I don’t think I would have gotten as good a result in terms of the quality of the science, either.”

In October, her students visited the Solar Decathlon in Washington, D.C., a competition for energy-efficient home design. Carrying cameras and iPods with microphones, the students viewed the model homes, recorded observations, and interviewed attendees. From this, they created a virtual tour of the event, which was tied into Google Earth, an application that allows users to view a satellite image of a location. “What we’ve created can be shared throughout the Penn State community,” she said.

Guertin’s students entered the SCA/Mazda Conservation in Action Multimedia Contest, which asks young people to pick an environmental issue, describe it, and come up with a solution. The entry could be in the form of a podcast, movie, or song. She said her students chose a range of topics and technologies and that she was thrilled with the creativity of their work.

She said she was struck when a student commented, “I didn’t realize I cared about this subject. Now I realize I can do something about it.” Guertin explained, “That ‘do something’ means the technology is there for them to help communicate what they’ve learned. They cared about the science and what got them into the science was learning not just that you need technology to take measurements in the field, but also that it can help communicate the science.”
