An Information-Based Approach to Identifying Rapid-Guessing Thresholds

ABSTRACT

The identification of rapid guessing is important to promote the validity of achievement test scores, particularly with low-stakes tests. Effective methods for identifying rapid guesses require reliable threshold methods that are also aligned with test taker behavior. Although several common threshold methods are based on rapid guessing response accuracy or visual inspection of response time distributions, this paper describes a new information-based approach to setting thresholds that does not share the limitations of other methods. A pair of information-based methods are introduced, and an empirical comparison study found the new methods to more reliably set thresholds than methods based on response accuracy or visual inspection.     

Examination of the gender–student engagement relationship at one university

Research examining the relationship between gender and student engagement at the post secondary level has provided mixed results. The current study explores two possible reasons for lack of clarity regarding this relationship: improper parameter estimation resulting from a lack of multi‐level analyses and inconsistent conceptions/measures of ‘student engagement’. Data from the 2006 administration of the National Survey for Student Engagement (NSSE) at a southeastern university were analysed. Results indicated that the relationship between gender and engagement is related to engagement type as well as an institution level factor (gender composition). Implications and directions for future research are discussed.     

Podcasting in higher education: What are the implications for teaching and learning?

A podcast is any digital media file, or series of files, distributed over the Internet for playback on portable media players and personal computers. This study explored the attitudes, perceptions, and use of podcasting as reported by instructors and students at a large American Midwestern university. The results of two online surveys were examined, focusing specifically on items related to teaching and learning. Findings suggest that students use podcast materials largely for reviewing concepts and issues raised in lectures that they have previously attended. While instructors and students agree that podcasts help students learn, students are less sure about whether podcasts improve instructors' teaching. The authors argue that podcasts can help instructors change face-to-face instruction from traditional didactic lectures to more constructivist learning practices.     

Ultrasound imaging in medical student education: Impact on learning anatomy and physical diagnosis

Ultrasound use has expanded dramatically among the medical specialties for diagnostic and interventional purposes, due to its affordability, portability, and practicality. This imaging modality, which permits real‐time visualization of anatomic structures and relationships in vivo, holds potential for pre‐clinical instruction of students in anatomy and physical diagnosis, as well as providing a bridge to the eventual use of bedside ultrasound by clinicians to assess patients and guide invasive procedures. In many studies, but not all, improved understanding of anatomy has been demonstrated, and in others, improved accuracy in selected aspects of physical diagnosis is evident. Most students have expressed a highly favorable impression of this technology for anatomy education when surveyed. Logistic issues or obstacles to the integration of ultrasound imaging into anatomy teaching appear to be readily overcome. The enthusiasm of students and anatomists for teaching with ultrasound has led to widespread implementation of ultrasound‐based teaching initiatives in medical schools the world over, including some with integration throughout the entire curriculum; a trend that likely will continue to grow.

Policy mobilities and methodology: a proposition for inventive methods in education policy studies

ABSTRACT

The argument of this paper is that new methodologies associated with the emerging field of ‘policy mobilities’ can be applied, and are in fact required, to examine and research the networked and relational, or ‘topological’, nature of globalised education policy, which cuts across the new spaces of policymaking and new modes of global educational governance. In this paper, we examine the methodological issues pertaining to the study of the movement of policy. Informed by contemporary methodological thinking around social network analysis and the ethnographic notion of ‘following the policy’, we discuss the limitations of these approaches to adequately address presence in policy network analysis, and the problem of representing speed and intensity of policy mobility, even while these attempt to solve the problem of relationality and territoriality. We conclude that the methodologies of policy mobility are inexorably intertwined with the (constantly) changing phenomena under examination, and hence require what Lury and Wakeford describe as ‘inventive methods’.     

Exploring Changes in Pre-service Elementary Teachers' Mathematical Beliefs

Research literature (e.g., Thompson, 1992)suggests that teachers' beliefs about thenature of mathematics provide a strongindicator of their future teaching practices. Moreover, current reform efforts (e.g., NCTM,2000) ask teachers to lead mathematicalexplorations that allow their own students toconstruct mathematics. Understandingprospective teachers' mathematical beliefs andthe circumstances under which these beliefsmight be changed is therefore critical toteacher educators. In this paper we describethe culture of a mathematics content course forprospective elementary teachers that isdesigned to provide participants with authenticmathematical experiences and to fosterautonomous mathematical behaviors. Using bothsurvey and interview data, we exploredparticipants' beliefs about the nature ofmathematical behavior both at the commencementand at the completion of the course. We arguethat the participants' beliefs became moresupportive of autonomous behaviors during thecourse. We report that students attributedchanges in beliefs to specific classroom socialnorms and sociomathematical norms that includedfacets of work on ``big' problems withunderlying structures, a broadening in theacceptable methods of solving problems, a focuson explanation and argument, and theopportunity to generate mathematics as aclassroom community.     

The influence of a peer-tutoring training model for implementing cooperative groupings with elementary students

This study examined the effects of peer-tutoring training on elementary school student communication and collaboration skills when used in conjunction with cooperative learning. Within six classes (grades 2–6) in an inner-city school, cooperative learning pairs were randomly assigned to two groups (control and training). Multivariate analyses of variance (MANOVA) of quantitative data from a systematic observation instrument used over an entire year showed that, in general, the training group surpassed the control group in both communication and collaborative skills. Students in grades 2–3 showed substantially more improvement than students in grades 4–6; also, students with average or below-average reading levels required more time to acquire these skills than did above-average students. The qualitative data further substantiated these findings while revealing a large variation among teachers in implementing cooperative learning. and is Editor of the Research section of this journal.     

Family of origin environments in two clinical samples of survivors of intra-familial, extra-familial, and both types of sexual abuse

OBJECTIVE: It has been suggested that survivors of ongoing childhood sexual abuse (CSA) tend to have been reared in ineffective family environments that render them particularly vulnerable to maltreatment and which foster psychological difficulties beyond those accounted for solely by their abuse. If this conjecture is valid, one would expect that the family of origin environments of CSA survivors would be disturbed whether their abuser was intra-familial or extra-familial. To assess this hypothesis, two studies compared the childhood family of origin environments and supportive parenting characteristics of a clinical sample of women sexually abused by family members only (the intra-familial group), by non-family members only (the extra-familial group), and by both family and non-family members (the "both" group). METHOD: Study 1 compared the three groups (total N = 213) using the Family Environment Scale (FES). Study 2 compared groups (total N = 86) on the positive parenting scales of the Exposure to Abusive and Supportive Environments Parenting Inventory (EASE-PI). RESULTS: In Study 1, multivariate analyses indicated significant differences on the independence, cohesion, and conflict subscales of the FES. Pairwise comparisons revealed that the extra-familial group reported significantly higher levels of family independence and lower levels of conflict than the other two groups. In addition, the extra-familial group reported higher levels of cohesion than the intra-familial group. However, the effect sizes of these comparisons were extremely small. In Study 2, multivariate analyses revealed no group differences on the EASE-PI scales. CONCLUSIONS: Low effect sizes on the three significant FES scales, non-significance on the remaining seven FES scales, and non-significance on the EASE-PI scales suggest that there is considerable similarity in the family of origin environments of adult female CSA survivors seeking therapy regardless of whether their perpetrators were family members, non-family members, or both family and non-family members.
