automotive threat Assessment Design for combined braking and steering maneuvers
IEEE Transactions on Vehicular Technology, 2013Co-Authors: Mohammad Ali, Esteban R Gelso, Jonas SjöbergAbstract:The active safety systems available in passenger cars today automatically deploy automated safety interventions in situations where the driver is in need of assistance. In this paper, we consider the process of determining whether such interventions are needed. In particular, we Design a threat Assessment method that evaluates the risk that the vehicle will either leave the road or its maneuverability will be significantly reduced within a finite time horizon. The proposed threat Assessment method accounts for combined braking and steering maneuvers, which results in a nonlinear dynamical vehicle behavior. We formulate the threat Assessment problem as a nonconvex constraint satisfaction problem (CSP) and implement an algorithm that solves it through interval-based consistency techniques. Experimental validation of the proposed approach indicates that constraint violation can be predicted while avoiding the detection of false threats.

CDC - Threat Assessment Design under driver parameter uncertainty
2012 IEEE 51st IEEE Conference on Decision and Control (CDC), 2012Co-Authors: Paolo Falcone, Jonas SjöbergAbstract:We consider a model-based threat Assessment method, which enables the activation of assisting safety interventions in case an accident threat to the driver is detected. The method relies on vehicle and driver mathematical models and reachability analysis tools. In particular, we focus on the problem of false threats detection that can occur due to uncertainties in the driver model, i.e., the driver is incorrectly deemed incapable of accomplishing a driving task. This paper proposes a novel approach, to compensate for uncertainties in the driver model, for the considered threat Assessment method. In particular, we show how the considered threat Assessment method can be Designed such that, if a threat is detected, the driver is guaranteed to be unable to perform the assigned driving task. In such case, an automated assisting intervention can be motivated.

Evidence-Centered Assessment Design
Assessing Model-Based Reasoning using Evidence- Centered Design, 2017Co-Authors: Robert J. Mislevy, Geneva Haertel, Michelle Riconscente, Daisy Rutstein, Cindy ZikerAbstract:Design patterns are tools to support task authoring under an evidence-centered approach to Assessment Design (ECD). This chapter reviews the basic concepts of ECD, focusing on evidentiary arguments. It defines the attributes of Design patterns, and shows the roles they play in creating tasks around valid Assessment arguments.

The Biomass Measurement Model
Bayesian Networks in Educational Assessment, 2015Co-Authors: Russell G. Almond, Robert J. Mislevy, Linda S. Steinberg, Duanli Yan, David M. WilliamsonAbstract:From one perspective, evidence-centered Assessment Design and Bayesian networks are just notations. In particular, it is easy to express familiar Assessment Design patterns using these notations. Bayesian networks are just a way to parameterize multidimensional latent class models. What have we gained?

Evidence-centered Design for simulation-based Assessment.
Military medicine, 2013Co-Authors: Robert J. MislevyAbstract:ABSTRACTSimulations provide opportunities for people to learn and to develop skills for situations that are expensive, time-consuming, or dangerous. Careful Design can support their learning by tailoring the features of situations to their levels of skill, allowing repeated attempts, and providing timely feedback. The same environments provide opportunities for assessing people's capabilities to act in these situations. This article describes an Assessment Design framework that can help projects develop effective simulation-based Assessments. It reviews the rationale and terminology of the “evidence-centered” Assessment Design framework, discusses how it aligns with the principles of simulation Design, and illustrates ideas with examples from engineering and medicine. Advice is offered for Designing a new simulation-based Assessment and for adapting an existing simulation system for Assessment purposes.

Three Things Game Designers Need to Know About Assessment
Assessment in Game-Based Learning, 2012Co-Authors: Robert J. Mislevy, John T. Behrens, Dennis C. Frezzo, Kristen E. Dicerbo, Patti WestAbstract:Designing game-based Assessments requires coordinating the work of people from communities with little overlap, such as subject matter experts, game Designers, software engineers, Assessment specialists, and psychometricians. This chapter discusses three things that game Designers should know about Assessment to help their work come together toward the common goal: (1) Assessment Design is compatible with game Design, because they build on the same principles of learning. (2) Assessment is not really about numbers; it is about the structure of reasoning. (3) The key constraints of Assessment Design and game Design need to be addressed, even if in rudimentary form, from the very beginning of the Design process. The Assessment Design framework called “evidenced centered Design” is introduced to complement game Design principles, so that Designers can address Assessment criteria such as reliability and validity jointly with game criteria such as engagement and interactivity. The ideas are illustrated with examples from the Packet Tracer simulation environment and Aspire game that are used in the Cisco Networking Academies for learning and assessing computer network engineering.

On the roles of external knowledge representations in Assessment Design
2010Co-Authors: Robert J. Mislevy, Daisy Rutstein, John T. Behrens, Randy E. Bennett, Sarah F. Demark, Dennis C. Frezzo, Roy Levy, Daniel H. Robinson, Valerie J. Shute, Ken StanleyAbstract:People use external knowledge representations (EKRs) to identify, depict, transform, store, share, and archive information. Learning how to work with EKRs is central to be-coming proficient in virtually every discipline. As such, EKRs play central roles in cur-riculum, instruction, and Assessment. Five key roles of EKRs in educational Assessment are described: (1) An Assessment is itself an EKR, which makes explicit the knowledge that is valued, ways it is used, and standards of good work. (2) The analysis of any domain in which learning is to be assessed must include the iden-tification and analysis of the EKRs in that domain. (3) Assessment tasks can be structured around the knowledge, relationships, and uses of domain EKRs. (4) "Design EKRs" can be created to organize knowledge about a domain in forms that support the Design of Assessment. (5) EKRs in the discipline of Assessment Design can guide and structure the domain analyses (#2), task construction (#3), and the creation and use of Design EKRs (#4). The third and fourth roles are discussed and illustrated in greater detail, through the per-spective of an "evidence-centered" Assessment Design framework that reflects the fifth role. Connections with automated task construction and scoring are highlighted. Ideas are illustrated with two examples: "generate examples" tasks and simulation-based tasks for assessing computer network Design and troubleshooting skills.
