Automatic grading systems, such as WebWork, are becoming much more widely used as they relieve the instructor from needing to grade student work, provide students with automatic feedback, and can allow for immediate resubmission. They have also been shown to improve the effectiveness of teaching and learning. In this paper, we apply Item Response Theory (IRT) to a large WebWork Calculus homework dataset...
In this paper we introduce new tools for measuring and visualizing the learning process of students in large classes where students are required to use a computer-supported problem solving learning environment (PSLE) either in class or as homework. These learning environments give students unlimited opportunities to propose a solution to the problem and give them immediate feedback. We show how to...
We have designed and built CalcTutor, an online educational tool for Calculus that employs the Teachers Dilemma methodology. This methodology is centered around a game framework where students take on, and are rewarded for playing well, both the role of learner and teacher. Students create machine-verifiable questions for each other and gain points based on not only correct answers but also asking...
We study an analog of Serreʼs conjecture over imaginary quadratic fields. In particular, we ask whether the weight recipe of Buzzard, Diamond and Jarvis will hold in this setting. Using a program written by the author, we provide computational evidence that this is in fact the case. In order to justify the method used in the program, we prove that a modular symbols method will work for arbitrary weights...
