We describe our on-going work in the creation of a web-based Intelligent Tutoring System (ITS) for the mathematics section of the Scholastic Aptitude Test (SAT). Wayang Oupost focuses on geometry problems, and uses web-based multimedia to communicate concepts to the student. Decisions about problem and help selection made on a remote web server, which stores data on student-system interactions ...

Due to its inherent discretion, passive detection is a convenient way for acoustic monitoring of maritime zone. In a context of harbour protection, one of the stakes is intruders detection e.g. scuba divers. However, the need for instantaneous reaction opens a field of research to improve the human operators’ detection tools. This article proposes a new approach of the SMF as a real-time passiv...

This paper reviews the state of the art of research on individual decision-making in high-stakes, low-probability settings. A central theme is that resolving high-stakes decisions optimally poses a formidable challenge not only to naı̈ve decision makers, but also to users of more sophisticated tools, such as decision analysis. Such decisions are difficult to make because precise information abou...

Cognitive functioning is critical as in our daily life a host of real-world complex decisions in high-stakes markets have to be made. The decision-making process can be vulnerable to environmental stressors. Summarizing the growing economic and epidemiologic evidence linking air pollution, cognition performance and real-world decision-making, we first illustrate key physiological and psychologi...

Recent work demonstrates that process data from intelligent tutoring systems (ITSs) can be used to predict student outcomes on high-stakes, standardized tests. Such models are important if ITSs are to be used for formative assessment and as replacements for external assessments. Recent work used various measures of learning efficiency and performance from problem-level, aggregate data from Carn...

Automatic essay scoring is nowadays successfully used even in high-stakes tests, but this is mainly limited to holistic scoring of learner essays. We present a new dataset of essays written by highly proficient German native speakers that is scored using a fine-grained rubric with the goal to provide detailed feedback. Our experiments with two state-of-the-art scoring systems (a neural and a SV...

Many factors have been proposed to explain the attrition of women in science, technology, engineering and math fields, among them the lower performance of women in introductory courses resulting from deficits in incoming preparation. We focus on the impact of mixed methods of assessment, which minimizes the impact of high-stakes exams and rewards other methods of assessment such as group partic...

We investigate whether math tests taken by German primary and secondary students during a high stakes grade produce higher scores than done low grades. define as the final of or school, because good performance in that can affect future opportunities. Our difference-in-differences estimates show increase on average 0.17 to 0.22 standard deviations grades, sizeable effect. Reading scores, howeve...

We report experimental results for a twice-played prisoners’ dilemma in which the players can choose the allocation of the stakes across the two periods. Our point of departure is the assumption that some (but not all) people are willing to cooperate, as long as their opponent is sufficiently likely to do so. The presence of such types can be exploited to enhance cooperation by structuring the ...

Experiments have shown that people have a natural taste for cooperation. This paper takes a first step in understanding how formal and informal institutions might be designed to utilize these private tastes to facilitate more efficient economic interactions. We examine a twice-played prisoner’ dilemma in which the total of the stakes in the two periods is fixed, but the distribution of these st...
