<From Thomas Lotze thomas@xxxxxxxxxxx> We at Grockit have just posted a new educational data mining competition focused on analyzing student performance and figuring out how to predict whether they can correctly answer future practice questions: ( http://www.kaggle.com/c/WhatDoYouKnow ). We're very excited to be reaching out to the data mining community to try to improve outcomes for education, and we hope some of you will be interested in taking part. Cash prizes will also be awarded to the top three finishers. This a data set from students studying for the GMAT, SAT, and ACT by answering practice questions at http://grockit.com -- we're hoping to find better ways of understanding students' abilities and the areas of knowledge that can be tested using these (mainly multiple-choice) questions. Using that, we hope to make our assessment better and help students really improve their learning. Almost 5,000,000 item responses (with 17 data fields each) are included in the training set provided, covering responses from >175,000 students working through 6,000+ questions. Details on the dataset, the prizes, and the competition are all available at: http://www.kaggle.com/c/WhatDoYouKnow You are, of course, more than welcome to publish work based on your techniques and results. Thanks for reading, and we hope you check it out!
