In peer mechanisms, the competitors for a prize also determine who wins. Each competitor
may be asked to rank, grade, or nominate peers for the prize. Since the prize can be …

In peer assessment, students assess a task done by their peers, provide feedback and
usually a grade. The extent to which these peer grades can be used to formally grade the …

We propose measurement integrity, a property related to ex post reward fairness, as a novel
desideratum for peer prediction mechanisms in many natural applications. Like robustness …

In this thesis, we use various AI techniques to address several scalability challenges in two
academic environments: large university classrooms and large peer-review conferences. In …

Mechanical TA 2 (MTA2) is an open-source, distributed peer grading system that boosts
performance by leveraging both trusted TAs and computationally intensive algorithms. The …

We develop a game-theoretical model of a classroom scenario, where n students
collaborate on a common task. We assume that there exists an objective truth known to the …

The mathematical study of information elicitation has led to elegant theories about the
behavior of economic agents asked to share their private information. Similarly, the study of …

The" free rider" problem has long plagued pedagogies based on collaborative learning. The
most common solution to the free rider problem is peer evaluation. As well other existing …

Most peer-evaluation practices rely on the evaluator's goodwill and model them as
potentially noisy evaluators. But what if graders are competitive, ie, enjoy higher utility when …
