A Bayesian-optimal principle for learner-friendly adaptation in learning games

Adaptive learning games should provide opportunities for the student to learn as well as motivate playing until goals have been reached. In this paper, we give a mathematically rigorous treatment of the problem in the framework of Bayesian decision theory. To quantify the opportunities for learning, we assume that the learning tasks that yield the most information about the current skills of the student, while being desirable for measurement in their own right, would also be among those that are efficient for learning. Indeed, optimization of the expected information gain appears to naturally avoid tasks that are exceedingly demanding or exceedingly easy as their results are predictable and thus uninformative. Still, tasks that are efficient for learning may be experienced as too challenging, and the resulting failures can lower motivation. Therefore, in addition to quantifying the expected informational benefit for learning of any prospective task to be presented next, we also model the expected motivational cost of its presentation, measured simply as the estimated probability of failure in our example model. We propose a “learner-friendly” adaptation algorithm that chooses the learning tasks by optimizing the expected benefit divided by the expected cost. We apply this algorithm to a Rasch-like student model implemented within a real-world application and present initial results of a pilot experiment.     

观察者公正敏感性对不公正信息加工的影响

为考查观察者公正敏感性对不公正信息加工（注意、解释）的影响,该研究开展了两个实验研究。在实验一中,让被试观看不公正影片剪辑或中性剪辑后,要求他们完成视觉探测任务,判断探测刺激是在不公正词汇还是中性词汇的左边或右边;在实验二中,让被试对一个模糊的暗含不公正意义的影片剪辑中的主角进行公正性评价。结果表明,当被试不公正概念被激活后,观察者公正敏感性高的被试比观察者公正敏感性低的被试对不公正信息的注意加工更集中和更自动,同时他们对模糊的信息解释为更不公正。     

最大信息量法在CCSPC评分中应用的效度证据

采用基于最大信息量法的多维项目反应理论模型估计计算机模拟心理咨询病例系统（CCSPC）的合成分数及四个模块分数,并收集效标效度证据、成长变化效度证据和内容效度证据,结果表明：五个指标与心理咨询师考试三级技能成绩的相关均达到显著,且高于其与三级理论成绩的相关;所有指标得分均随着心理学学历升高而升高;多数指标分数随心理学本科年级提高而提高;获得心理咨询师资格认证的被试在CCSPC上有更高的得分.     

登机牌信息要素及其布局研究

随着民航行业的快速发展,飞机登机牌的使用率越来越高,而不同航空公司所采用的登机牌在信息内容和布局设计等方面均缺乏相关的设计规范,因此有必要从可用性角度对登机牌进行系统的研究.首先,采用KANO问卷法对登机牌上的文字信息要素进行研究,并基于研究结果设计出新登机牌;然后,从搜索绩效和主观偏好两个方面对新旧登机牌进行比较评价研究.结果显示：①登机牌上必须呈现的信息主要包括登机时间、登机口、航班号、座位号、姓名、日期和目的地七项必要信息,以及可提高旅客使用体验的预计飞行时间信息,但登机牌上不能呈现旅客身份证号码等个人隐私信息;②基于信息要素研究结果重新布局设计的新登机牌在搜索绩效和主观偏好方面均显著优于现有登机牌.本研究结果可为将来的登机牌设计提供科学依据.     

Exercising Research Skills: An Information Literacy Boot Camp for Religious Studies Graduate Assistants

Instructional librarians at the University of Dayton collaborated with a religious studies graduate program to offer a three-day information literacy workshop, or “boot camp,” to the program's graduate research assistants. The graduate program had found that the assistants' research skills did not meet the expectations of their faculty mentors, and the workshop sought to address these deficiencies. With input from the religious studies faculty, the workshop focused on catalog and database searching, Boolean logic, primary sources, and the Chicago citation style. The librarians incorporated active learning exercises into each workshop session. Assessment of the workshop suggested that the assistants gained confidence in these information literacy skills. Feedback from faculty also indicated that the assistants' research skills had improved.     

Online Primary Sources in Religious Studies: Active Learning Exercises for Information Literacy Instruction

Online primary sources are a valuable resource for undergraduate students in religious studies courses. They provide firsthand, factual information about the beliefs and practices of religious traditions, movements, cults, and so on. In addition, they are readily and freely accessible online. Given their value as an information resource, undergraduate students need to be able to identify primary sources and understand how to use them in academic research. The purpose of this article is to describe activities for information literacy instruction that focus on primary sources in religious studies. These activities are intended as a resource for academic librarians who are teaching—or who plan to teach—undergraduate students how to identify and use primary sources.     

New Horizons: A Center for Research into Information and Religion

This article introduces the creation of a new research center focused on the study of information and religion. The Center, located at Kent State University, provides a new opportunity for scholars in the field of library and information science to collaborate with researchers in other disciplines in the exploration of many potential intersections of information and religion. The Center founders have already begun to present and publish in this area. Planned symposia and an annual conference add to the exposure of interested parties to ongoing studies in this field.     

Core Resources for a Cooperative Program in Diaconal Ministry

Abstract

This article provides an annotated listing of print and electronic resources to support a graduate Diaconal Ministries program based at the Lutheran Theological Seminary at Gettysburg, Pennsylvania. Suggested resources are categorized and related to all facets of the curriculum of the program that involve academic preparation in the areas of Lutheran theology, ministry and social service.     

Orthodox Worship

Abstract

This article attempts to convey both the riches of the experience of Orthodox Christian worship and the wealth of materials used in the liturgical celebration. There will be a discussion of the setting, the temple, and the modes of participation in the worship experience. The place of the senses in the experience will be noted, along with a sampling of the texts used. The article also contains a full discussion of the many liturgical texts required. An annotated bibliography of books and list of websites, together with a select glossary, are included.
