Predicting Robust Learning With the Visual Form of the Moment-by-Moment Learning Curve

We present a new method for analyzing a student's learning over time for a specific skill: analysis of the graph of the student's moment-by-moment learning over time. Moment-by-moment learning is calculated using a data-mined model that assesses the probability that a student learned a skill or concept at a specific time during learning (Baker, Goldstein, & Heffernan, 2010 Baker, R. S. J. d., Goldstein, A. B. and Heffernan, N. T. 2010. “Detecting the moment of learning”. In Proceedings of the 10th Annual Conference on Intelligent Tutoring Systems 25–34. In V. Aleven, J. Kay, & J. Mostow (Eds.),pp.Heidelberg, Germany: Springer.[Crossref] , [Google Scholar], 2011). Two coders labeled data from students who used an intelligent tutoring system for college genetics. They coded in terms of 7 forms that the moment-by-moment learning curve can take. These labels are correlated to test data on the robustness of students’ learning. We find that different visual forms are correlated with very different learning outcomes. This work suggests that analysis of moment-by-moment learning curves may be able to shed light on the implications of students’ different patterns of learning over time.  相似文献   

Relationships Among Measures as Empirical Evidence of Validity: Incorporating Multiple Indicators of Achievement and School Context     

Pete Goldschmidt  Jose Felipe Martinez  David Niemi  Eva L. Baker 《Educational Assessment》2013,18(3-4):239-266

In this article we examine empirical evidence on the criterion, predictive, transfer, and fairness aspects of validity of a large-scale language arts performance assessment, referred to as the Performance Assignment (PA). We use multilevel models to avoid biased inferences that might result from the naturally nested data. Specifically, we examine the relationships of the assessment with the Stanford Achievement Test, 9th Edition and the California High School Exit Examination. The results indicate that the measures are related, that students demonstrate a degree of transfer, and that the language arts PA is relatively more fair than comparison assessments. The results are robust to various model specifications and demonstrate that benefits do not accrue to all students equally.  相似文献   

Students' Perception of School Violence and Math Achievement in Middle Schools of Southern Italy     

Andrea Caputo 《Educational Assessment》2013,18(4):269-284

This study aims at both investigating bullying episodes occurring at school across different grades (from 6 to 8) and evaluating whether educational achievement in math can be predicted on the ground of students' perception of school violence. The sample was composed of 11,064 students coming from middle schools of Southern Italy. Standardized tests were submitted to measure students' performance in mathematics. Background questionnaires were used to assess students' perception of school violence in relation to some bullying episodes occurring in the last month. Students' perception of school violence, which tends to decrease from Grade 6 to 8, can be considered a valid predictor of their math performance, also controlling for both individual and family background, school context, and geographical characteristics.  相似文献   

Building Relationships through a Digital Branch Library: Finding the Community in Community College Library Websites     

Andrea M. Pampaloni  Nora J. Bird 《Community College Journal of Research & Practice》2013,37(12):1125-1141

This study evaluates whether or not community college libraries have in place the characteristics necessary to develop digital branch libraries to meet the expanding and changing needs of their publics. Using Hon and Grunig’s (1999) relationship building criteria as a framework, 98 community college library websites were analyzed to determine if they can be considered digital branch libraries (King, 2009). Digital branches go beyond offering mere functionality to embody relational aspects that are critical to the success of service-based organizations. That is, they provide at least the same level of services as their brick and mortar counterparts through real staff, real collection, real building, and real community. Findings indicate that while aspects of all of King’s criteria were present, representation was inconsistent and often weak; further, the emphasis was on functional features, suggesting a need for greater relationship building practices in order to engage with their publics. Collective results are discussed, and recommendations for improvement and areas of future research are offered.  相似文献   

THE IMPACT OF COLLECTIVE BARGAINING ON FACULTY COMPENSATION IN COMMUNITY COLLEGES     

H. Kent Baker 《Community College Journal of Research & Practice》2013,37(1-4):193-204

This study examines the impact of collective bargaining on faculty compensation at two‐year colleges over the period 1970‐81. The results show that faculty at unionized community colleges have not experienced significantly greater increases in compensation than their nonunionized brethren. In fact, the nonunion institutions actually experienced higher relative gains in compensation for the first three years after the unionized colleges first engaged in collective bargaining.  相似文献

Integration of knowledge management and collaborative learning by technical supported communication processes     

Andrea Kienle 《Education and Information Technologies》2006,11(2):161-185

To date the development of technical systems to support learning either in schools and universities (CSCL-systems), or in companies (knowledge-management systems) have largely developed separately concurrent, with no or little mutual exchange of experience. The approach presented here seeks to combine the strengths of both lines of development in order that both benefits from each others advantages achieve advantages for each development. Detailed requirements engineering is presented regarding, three research fields: communication theory; learning processes; and a study in companies. The requirements collected led to a sophisticated concept of annotations where annotations serve as communicative contributions, and (segmented) material is used as context. The combination and distinction between communicative contributions, and the material itself is a suitable approach for integrating the advantages of CSCL-systems (communication support) and knowledge management systems (support of content storage). These requirements are combined in a software system, KOLUMBUS, presented with its key features. To gather experience with KOLUMBUS and to convey potential for further improvement, two case studies were conducted. The main results, advantages and further potentials derived from these two case studies are described in this paper. The paper concludes with design recommendations for similar technical systems, as well as organizational hints for CSCL-groups (in schools or universities as well as in companies).  相似文献   

Sonic Oppression,Echoes of Resistance and the Changing Soundscapes of Rio’s Favelas in the Build-Up to the Olympics     

Andrea Medrado  Renata Souza 《Journal of Radio & Audio Media》2017,24(2):289-301

This article aims to explore the ways in which the transformations that Rio de Janeiro experienced prior to hosting the Olympics echo in the soundscapes of Favela da Maré. Here, we draw from an (auto)ethnographic approach, and combine theoretical perspectives from sound studies, auditory culture, and studies of activist media. Our research indicates that some of the authorities’ oppressive impositions on favela residents’ daily lives manifest precisely through the suppression of sounds. We would like to argue that activist media in Latin America can be better understood if situated in a complex set of daily rhythms.  相似文献
