For the first decades of computing, the term “algorithm” wasn’t much mentioned. But as computer science departments began sprouting across campuses in the 60s, the term acquired a new cachet. Its vogue was the product of status anxiety. Programmers, especially in the academy, were anxious to show that they weren’t mere technicians. They began to describe their work as algorithmic, in part because it tied them to one of the greatest of all mathematicians – the Persian polymath Muhammad ibn Musa al-Khwarizmi, or as he was known in Latin, Algoritmi. During the 12th century, translations of al-Khwarizmi introduced Arabic numerals to the west; his treatises pioneered algebra and trigonometry. By describing the algorithm as the fundamental element of programming, the computer scientists were attaching themselves to a grand history. It was a savvy piece of name-dropping: See, we’re not arriviste, we’re working with abstractions and theories, just like the mathematicians!
John Pearce on 02 Jun 12In some ways, the flipped model is an improvement. Research shows that tailored tutoring is more effective than lectures for understanding, mastery, and retention. But the flipped classroom doesn't come close to preparing students for the challenges of today's world and workforce. As progressive educational activist Alfie Kohn notes, great teaching isn't just about content but motivation and empowerment: Real learning gives you the mental habits, practice, and confidence to know that, in a crisis, you can count on yourself to learn something new. That's crucial in a world where, according to the U.S. Department of Labor Statistics, adults change careers (not just jobs) four to six times or where, as an Australian study predicts, 65% of today's teens will end up in careers that haven't even been invented yet. We don't need to flip the classroom. We need to make it do cartwheels.
