San Diego, Oct. 30, 2012 -- Computer scientists at the University of California, San Diego and at St. Petersburg Academic University in Russia, have developed a one-of-a-kind, hands-on online learning tool that weaves together for the first time science and programming education—and automatically grades homework too.
Rosalind primarily targets biologists who want to learn bioinformatics, and is also helpful for biology or computer science professionals who want to learn more about bioinformatics. The platform has already attracted more than 1,600 beta testers from more than 50 countries. “Rosalind is already helping students who are brave enough to dive into bioinformatics without waiting for their universities to update their curricula, and it’s only a matter of time before this model spreads to other disciplines,” Pevzner said.
The beta version of Rosalind became available only six weeks ago, but students from six different continents have already solved all the problems in the platform, said Vyahhi. “To keep up with them, the Rosalind team aims to add 100 new problems by the end of the year.”
Rosalind begins with a simple computational problem: given a strand of DNA, count the number of times that each of the four nucleotides appears in the strand. Subsequent exercises steadily grow in complexity, creating a problem tree in which the students’ biological and computational knowledge is constructed simultaneously. After solving only a few dozen problems, students will possess a wide arsenal of bioinformatics algorithms and will be prepared to tackle advanced problems that even graduate students may find challenging.
“The way in which Rosalind problems build on each other ensures that students are continuing to process the material instead of simply regurgitating notes for a test,” said Pevzner. “Completing Rosalind problems constitutes mastery of the subject, which is difficult to achieve with traditional courses online. I am happy to give top Rosalind students an A even though they have not attended my class.”
Rosalind is a joint project between UC San Diego and St. Petersburg Academic University. The project is supported by the Howard Hughes Medical Institute and the Russian Ministry of Science and Education.
Rosalind was named after Rosalind Franklin, a British X-ray crystallographer whose findings were used by Francis Crick and James Watson to formulate their hypothesis that DNA is structured as a double helix.
