On Being a Virtual World Librarian: Experiences in Offering Live Reference Services in a Virtual World

The reference collection holds an important place within the library. The proper maintenance of this collection through weeding is a critical yet often overlooked aspect of collection management. This article offers a case study describing a reference collection weeding project, including the development of a reference collection policy, a review of standing orders, the goals and outcomes of the review, and a discussion of the benefits of the project.     

Testing Expert-Based Versus Student-Based Cognitive Models for a Grade 3 Diagnostic Mathematics Assessment

The purpose of this study was to evaluate the adequacy of three cognitive models, one developed by content experts and two generated from student verbal reports for explaining examinee performance on a grade 3 diagnostic mathematics test. For this study, the items were developed to directly measure the attributes in the cognitive model. The performance of each cognitive model was evaluated by examining its fit to different data samples: verbal report, total, high-, moderate-, and low ability using the Hierarchy Consistency Index (Cui & Leighton, 2009), a model-data fit index. This study utilized cognitive diagnostic assessments developed under the framework of construct-centered test design and analyzed using the Attribute Hierarchy Method (Gierl, Wang, & Zhou, 2008; Leighton, Gierl, & Hunka, 2004). Both the expert-based and the student-based cognitive models provided excellent fit to the verbal report and high ability samples, but moderate to poor fit to the total, moderate and low ability samples. Implications for cognitive model development for cognitive diagnostic assessment are discussed.     

Systems Analysis,Interviewing, and the Improv

Interviewing is a critical skill for systems analysts. This article describes an experiment using student actors as interviewees for in‐class exercises to teach interviewing in the junior‐level systems analysis course. The experiment proved beneficial to the class, to the actors, and to the senior IS majors who helped the actors prepare.     

Supporting Educators to Implement Mand Training for a Student with Multiple Disabilities

ABSTRACT

The purposes of the study were to assess the effects of an online learning module on the implementation of mand training by a classroom team and determine whether training improved manding for a student with multiple disabilities. The classroom team utilized the Support Needs Assessment and Planning (SNAP) process to identify supports and guide implementation of the mand training procedures. The results indicate that both the special education teacher and paraprofessional were able to implement the mand training strategy with fidelity after completing the online module and student manding increased. The classroom team reported that both the online learning module and SNAP process were valuable for planning and implementing research-based supports. Limitations, implications for practice, and future research considerations are addressed.     

Significance,Effect Sizes,Stepwise Methods,and Other Issues: Strong Arguments Move the Field

The author asserts that editors should publicly declare their expectations and expose the rationales for editorial policies to public scrutiny. He argues that editorial policies ought to require effect size reporting, as those at 17 journals now do. He also argues (a) that score reliabilities should be reported; (b) that stepwise methods should not be used; (c) that structure coefficients should be interpreted; and (d) that if used wisely, confidence intervals differ from hypothesis tests in important ways. The use of noncentral t and F distributions to create confidence intervals about effect sizes also is appealing.     

Statistical Techniques Employed in AERJ and JCP Articles from 1988 to 1997: A Methodological Review

The authors of the present methodological review investigated the patterns of statistical usage and reporting practices in 756 articles published in the American Educational Research Journal (AERJ) and in the Journal of Counseling Psychology (JCP) over a 10-year period. First, some findings from other similar reviews are summarized. Second, the authors present a framework for characterizing selected research practices that emphasizes, in part, elements of the recent report of the American Psychological Association (APA) Task Force on Statistical Inference (Wilkinson & APA Task Force on Statistical Inference, 1999). Third, characterizations of 10 years of analytic practices in 2 journals are presented and evaluated within that framework. The article concludes with a discussion of the changes that may be necessary to improve the statistical state of affairs in behavioral research.     

A new approach to an old problem

Applying theories of cognition and affect that predict emotional responses to a stimulus on the basis of prior affect toward specific cues included in that stimulus, a study was conducted assessing individuals' fear and enjoyment reactions to horror films. Prior fear of specific cues included in each film was a significant predictor of overall fear reactions, after controlling for prior exposure to the film, fear of specific cues not included in the film, and manifest anxiety. Prior liking of specific cues included in each film did not emerge as a significant predictor of overall enjoyment. The contributions of gender and of level of forewarning about the film's content were also assessed.     

Adult learners’ perceptions of an undergraduate HRD degree completion programme: reasons for entering,attitudes towards programme and impact of programme

The purpose of the study was to evaluate an undergraduate distance education (DE) programme based upon adult learners’ perceptions. The study investigated the value of the Human Resource Development programme at the University of Arkansas by examining the students’ reasons for returning to college, their attitudes towards the programme and the impact that the programme has had upon their lives. The respondents viewed DE as the best opportunity for adult students to complete their degrees. Female participants had significantly more positive attitudes towards DE than male participants did. The respondents had positive attitudes towards the learning environment, the instructors in the programme, the cohort design of the programme and the content of the programme. However, there were mixed opinions concerning the economic benefit of participation in the programme.     

Does student engagement in self-assessment calibrate their judgement over time?

One of the implicit aims of higher education is to enable students to become better judges of their own work. This paper examines whether students who voluntarily engage in self-assessment improve in their capacity to make those judgements. The study utilises data from a web-based marking system that provides students with the opportunity to assess themselves on each criterion for each assessment task throughout a programme of study. Student marks were compared with those from tutors to plot changes over time. The findings suggest that overall students’ judgements do converge with those of tutors, but that there is considerable variation across achievement levels, with weaker students showing little improvement. Whilst the study is limited by the exigencies of voluntary participation and thus consequential gaps in the data set, it shows how judgement over time can be demonstrated and points to the potential for more systematic interventions to improve students’ judgements. It also illustrates the use of the web-based marking and feedback software (ReView) that has considerable utility in aiding self-assessment research.
