A Comparison of Self-Adapted and Computerized Adaptive Tests

According to item response theory (IRT), examinee ability estimation is independent of the particular set of test items administered from a calibrated pool. Although the most popular application of this feature of IRT is computerized adaptive (CA) testing, a recently proposed alternative is self-adapted (SA) testing, in which examinees choose the difficulty level of each of their test items. This study compared examinee performance under SA and CA tests, finding that examinees taking the SA test (a) obtained significantly higher ability scores and (b) reported significantly lower posttest state anxiety. The results of this study suggest that SA testing is a desirable format for computer-based testing.     

Academics’ perceptions of the benefits and challenges of self and peer assessment in higher education

Despite compelling evidence of its potential effectiveness, uptake of self and peer assessment in higher education has been slower than expected. As with other assessment practices, self and peer assessment is ultimately enabled, or inhibited, by the actions of individual academics. This paper explores what academics see as the benefits and challenges of implementing self and peer assessment, through the analysis of interviews with 13 Australian academics. Thematic analysis of our qualitative data identified seven themes of benefits and five challenges. Our academics showed strong belief in the power of self and peer assessment as formative assessment, contrary to past literature which has focussed on the accuracy of students’ marking. This paper therefore brings insights as to not only what academics value about self and peer assessment but also identifies potential inhibitors in practice. Recommendations are made about improving the design and implementation of self and peer assessment in higher education.     

Effects of “Like Type” Sex Pairings between Applicants–Principals and Type of Focal Position Considered at the Screening Stage of the Selection Process

This study addresses the screening decisions for a national random sample of high school principals as viewed from the attraction-similarity theory of interpersonal perceptions. Independent variables are the sex of principals, sex of applicants, and the type of focal positions sought by hypothetical job applicants (teacher or counselor). Dependent variables are principals’ assessments of job candidates’ skills on specific job related criteria and the perceived probability of extending job candidates an interview opportunity. Principals’ assessments of hypothetical applicants were cast into a 2×2×2 completely crossed factorial design and were analyzed through a stepdown analysis of variance procedure. By approaching selection as a process, these results fit within the tenets as suggested by the attraction-similarity paradigm. Similar sex pairings between principals and applicants were more likely to be extended interview offers than dissimilar sex pairings regardless of the focal position under consideration.This research was supported in part by the University of California Educational Research Center (UCERC).

Reciprocal teaching and reading comprehension: a review

Reading researchers recently have turned their attention to co-operative forms of learning and teaching. One particular form of co-operative teaching is reciprocal teaching which involves the reciprocal interaction of experts and novices in explicit, overt demonstrations of strategy use. Scaffolding, active meaningful involvement, feedback, and fading of the expert's leading the interactions are seen as critical elements of the technique. This paper outlines the theoretical underpinnings of the technique and reviews research examining the effects of reciprocal teaching of comprehension strategies (summarising, predicting, clarifying, questioning) on comprehension disabled subjects. In general the findings show powerful effects, effects that transfer and generalise. The potential of the technique for enhancing other reading skills is discussed.     

Structure,Impact, and Deficiencies of Beginning Counselor Educators' Doctoral Teaching Preparation

The authors utilized the consensual qualitative research method (Hill, Thompson, & Williams, 1997 ) to explore beginning counselor educators' (N = 9) experiences of doctoral teaching preparation, including helpful and missing components. Emerging themes included a lack of intentionality in teaching‐related program design and a need for stronger preparation in pedagogy and content delivery methods.     

Teachers’Choice of Storybooks: What Messages do Children Hear?

An important dimension to the teaching of literacy must be the quality of the texts provided for children to read. The features of reading texts in schools have only recently become the object of sustained inquiry but it appears there are some interesting issues in the different perceptions children and teachers may have of these texts. Phil Kirby explores some of these issues in this article and provides excellent evidence that choice of story books is not the simple issue it might appear.     

Femoral indicator injection for transpulmonary thermodilution using the EV1000/VolumeView®: do the same criteria apply as for the PiCCO®?

Objective

Comparison of global end-diastolic volume index (GEDVI) obtained by femoral and jugular transpulmonary thermodilution (TPTD) indicator injections using the EV1000/VolumnView® device (Edwards Lifesciences, Irvine, USA).

Methods

In an 87-year-old woman with hypovolemic shock and equipped with both jugular and femoral vein access and monitored with the EV1000/VolumeView® device, we recorded 10 datasets, each comprising duplicate TPTD via femoral access and duplicate TPTD (20 ml cold saline) via jugular access.

Results

Mean femoral GEDVI ((674.6±52.3) ml/m²) was significantly higher than jugular GEDVI ((552.3±69.7) ml/m²), with P=0.003. Bland-Altman analysis demonstrated a bias of (+122±61) ml/m², limits of agreement of ?16 and +260 ml/m², and a percentage error of 22%. Use of the correction-formula recently suggested for the PiCCO® device significantly reduced bias and percentage error. Similarly, mean values of parameters derived from GEDVI such as pulmonary vascular permeability index (PVPI; 1.244±0.101 vs. 1.522±0.139; P<0.001) and global ejection fraction (GEF; (24.7±1.6)% vs. (28.1±1.8)%; P<0.001) were significantly different in the case of femoral compared to jugular indicator injection. Furthermore, the mean cardiac index derived from femoral indicator injection ((4.50±0.36) L/(min·m²)) was significantly higher (P=0.02) than that derived from jugular indicator injection ((4.12±0.44) L/(min·m²)), resulting in a bias of (+0.38±0.37) L/(min·m²) and a percentage error of 19.4%.

Conclusions

Femoral access for indicator injection results in markedly altered values provided by the EV1000/VolumeView®, particularly for GEDVI, PVPI, and GEF.

     

A framework for designing,implementing, communicating and researching peer assessment

The term ‘peer assessment’ may apply to a range of student activities. This imprecision may impact on the uptake of peer assessment pedagogies. To better describe peer assessment approaches, typologies of peer assessment diversity were previously derived from the education literature. However, these typologies have not yet been tested with ‘real-life’ peer assessment examples, nor do they consider broader contextual matters. We present an augmented peer assessment framework, refined through analysing faculty accounts of their peer assessment practices. Our framework subsumes previous attempts to classify peer assessment, and extends them to include technology use, resources and policy, which were new features of our data not present in previous frameworks. In the current higher education climate, these considerations may be crucial for the scalability and success of peer assessment. The framework proposed in this paper provides both precision and concision for researchers and educators in studying and implementing peer assessment.
