We consider a model of strategic trading with asymmetric information of an asset whose value follows a Brownian motion. An insider continuously observes a signal that tracks the evolution of the asset’s fundamental value. The value of the asset is publicly revealed at a random time. The equilibrium has two regimes separated by an endogenously determined time T . In [0 T ), the insider gradually...

We built software to support student reasoning about a phenomenon and development of hypotheses to explain it. The goal is to engage students in asking questions, generating hypotheses and testing predictions. Rashi, an intelligent tutor, tracks students’ investigations (e.g., hypotheses, questions, data collection, and inferences) and helps articulate how evidence and theories are related. The...

Ziel des Beitrags ist, einen Überblick über aktuelle Entwicklungen und Ausprägungen von MOOCs sowie die Erfahrungen und Ergebnisse aus der Untersuchung von zwei MOOCs vorzustellen, die 2011 und 2012 durchgeführt wurden. Besondere Schwerpunkte liegen dabei auf der Bedeutung und Ausprägung der Beteiligungsformen in den verschiedenen MOOC-Formaten, der Beteiligung in den beiden untersuchten MOOCs ...

SPOC is not only a MOOC supplement but also the product of MOOC and traditional teaching method’s integration innovation, which cause the extensive concern of the global education. This article starts with mastering advanced concepts and the basic process of mastery learning theory, followed by a deep analysisof SPOC through mastery learning theory, and finally put forwards enlightenment on tea...

The following paper describes the results of an experiment in the hybrid use a newly developed online platform for what we are calling contemplative reading. First taught in face to face courses, the platform was developed to help students engage with Dante’s Divine Comedy at multiple levels by mimicking in digital form the medieval manuscript’s marginalia and reflective aspects. The analysis d...

This paper studies a model of strategic trading with asymmetric information of an asset whose value follows a Brownian motion. An insider continuously observes a signal that tracks the evolution of the asset’s fundamental value. The value of the asset is publicly revealed at a random time. The equilibrium has two regimes separated by an endogenously determined time T . In [0, T ), the insider g...

University-based program (University track) was established in 1843 and Cleveland Clinic-based Cleveland Clinic Lerner College of Medicine (College track) was established in 2002. University track implemented a major curriculum revision in 2006, focusing on development of lifelong learners and incorporating themes of scholarship, clinical mastery, leadership, and civic professionalism. A dedica...

Observations show that large variations in the strength of the stratospheric circulation, appearing first above approximately 50 kilometers, descend to the lowermost stratosphere and are followed by anomalous tropospheric weather regimes. During the 60 days after the onset of these events, average surface pressure maps resemble closely the Arctic Oscillation pattern. These stratospheric events ...

In this paper we introduce an automated assessment service for online learning support in the context of communities of learners. The goal is to introduce automatic tools to support the task of assessing massive number of students as needed in Massive Open Online Courses (MOOC). The final assessments are a combination of tutor’s assessment and peer assessment. We build a trust graph over the re...
