Spec score 7.2 #20 of 24 in Biology Learning Software

What it is

Rosalind is a free web learning platform that teaches bioinformatics and programming through problem solving. Its tracks include Python Village, Bioinformatics Stronghold, Bioinformatics Armory, Bioinformatics Textbook Track, and Algorithmic Heights. Python Village introduces programming basics, while Stronghold covers mass spectrometry, sequence alignment, genome assembly, phylogeny, probability, and string algorithms. Submissions are checked automatically. Learners may code on their own computers and upload or paste answers, using any programming language. Rosalind targets biologists developing programming skills and programmers new to computational molecular-biology problems. Faculty can create classes, assign problems, monitor progress, review submissions, and use a grade sheet; Faculty accounts are free. Problems impose time limits and waiting after incorrect answers. The Faculty page says plagiarism checking was being implemented, requiring instructors to compare code themselves meanwhile. Public access costs nothing.
