ASU Online science course brings to life a new way of teaching
Arizona State University’s School of Earth and Space Exploration recently released new research on its flagship Smart Course, "Habitable Worlds," published in the peer-reviewed journal, Astrobiology. The study found that its student-centered, exploration-focused design resulted in high course grades and demonstrable mastery of content.
Created for non-science majors, Habitable Worlds (HabWorlds) uses interactive simulations and virtual field trips to introduce astronomy, biology, chemistry, geology and physics to students as they explore the search for life beyond Earth. The online course was created by the Center for Education Through eXploration (ETX) at ASU, with support from NASA and the National Science Foundation. Since 2011, it has been taken by more than 5,000 ASU students and adopted by instructors at nearly 40 other institutions globally.
In the published research, co-creator of the course Lev Horodyskyj and the team of researchers, instructors, and programmers who created HabWorlds describe the digital design philosophy they used to develop and implement the course.
“With HabWorlds, we wanted to bring to life a new way of teaching science. Our goal was to create an interactive, game-like science course that teaches science as it really is — a systematic process of exploring the unknown, not just memorization of known facts,” said Ariel Anbar, fellow co-creator of the course and director of ETX.
Through the use of Smart Sparrow’s learning platform, instructors are able to access learner analytics captured throughout the learning experiences. They can identify common trouble areas for their students and make rapid design and content improvements to ensure students meet the learning objectives of every lesson.
“Because of the way HabWorlds is designed and our ability to use Smart Sparrow’s course analytics to dig deeper into what students do throughout the lesson, we can clearly measure their understanding and mastery of content as demonstrated through their behaviors,” Horodyskyj said.
The research also shared student learning outcomes and evaluation data from over the past six years. Analysis showed that the consistently higher grades through use of the course are a result of better concept mastery and efficient problem-solving, not simplified concepts or easier grading than the traditional instruction.
“What’s fascinating about this research is it provides evidence that the students who received high grades are actually reasoning more effectively that those who didn’t, based on how they behaved in the gameful learning system,” said Dror Ben-Naim, CEO of Smart Sparrow. “This demonstrates the kinds of novel assessments that are made possible with technology that’s married with smart design.”

Students taking the Habitable Worlds online course use interactive simulators, like this one, to poke and prod scientific models, helping them understand concepts better than static images. This stellar nursery simulator allows students to create stars and watch as they live and die.
The carbon cycle simulator allows students to explore how carbon interacts with geological systems like mountains, volcanoes, and plate tectonics.
The Drake Equation simulator allows students to manipulate the terms of the Drake Equation to see which stars in the night sky might have communicating alien civilizations.
The redox simulator allows students to power a virtual organism using a variety of food molecules from glucose to selenium.
