Examination standards and the limits of linking

There is a tendency in the literature to characterize linking as equating done somewhat less rigorously. The ambiguity of this conception can lead to confusion amongst policy‐makers and members of the public and can result in the proliferation of comparability myths. As the constructs assessed by two tests decrease in similarity, so the difference between equating and linking becomes one of kind rather than degree. To help make sense of linking in different contexts, a general model is proposed, based upon the idea of a ‘linking construct’. This general model is used to define the limits of linking and to clarify what users and stakeholders need to know about linking and linked scores. Finally, a distinction is drawn between judgemental linking as a method (e.g., social moderation) and judgemental linking as a theory (i.e., the value judgement theory of linking). The latter presents a challenge to the general model, which is defended.     

Deficiency,Contamination, and the Signal Processing Metaphor

Educational assessment involves eliciting, transmitting, and receiving information concerning the level of proficiency of a learner in a specified domain. With that in mind, it is perhaps surprising that the literature seems to make very little use of the signal processing metaphor. The present article begins by making a general case for greater use of this metaphor, as a simple and intuitive thinking tool for helping to explain how educational assessment works. The main body of the article extends this argument by demonstrating the utility of the metaphor in helping to explain how educational assessment can go wrong. During the 1980s and 1990s, Samuel Messick extensively discussed two major ways in which educational assessment can go wrong via construct-irrelevant variance and construct underrepresentation, respectively. Despite their importance, these concepts have had only a limited impact on the literature. Part of the reason for this may be a lack of clarity and comprehensiveness in their articulation. The present article aims to articulate these concepts more clearly and comprehensively, within a framework provided by the signal processing metaphor, reconfiguring them as signal contamination and signal deficiency, respectively.     

Why Are We Here? A Five‐year Study of Institutional Development in a Secondary School

A process of survey feedback for internal renewal in a secondary school is analyzed in this article. Both qualitative and quantitative data, collected over a five‐year period, reveal that a number of interacting factors affected the process at various stages. Implications of the study center around school culture (norms), the community context, the importance of continuity of leadership and the integration of school‐level and system‐level initiatives.     

An exploration of the professional competencies required in engineering asset management

Engineering asset management (EAM) is a rapidly growing and developing field. However, efforts to select and develop engineers in this area are complicated by our lack of understanding of the full range of competencies required to perform. This exploratory study sought to clarify and categorise the professional competencies required of individuals at different hierarchical levels within EAM. Data from 14 field interviews, 61 online surveys, and 10 expert panel interviews were used to develop an initial professional competency framework. Overall, nine competency clusters were identified. These clusters indicate that engineers working in this field need to be able to collaborate and influence others, complete objectives within organisational guidelines, and be able to manage themselves effectively. Limitations and potential uses of this framework in engineering education and research are discussed.     

Dissection versus Prosection: A Comparative Assessment of the Course Experiences,Approaches to Learning,and Academic Performance of Non-medical Undergraduate Students in Human Anatomy

Many institutions rely upon prosection-based laboratories as more resource-efficient and time-effective alternatives to traditional cadaver dissection for human anatomy education. To facilitate growing enrollment numbers despite resource limitations, the University of Guelph (a non-medical institution) introduced a modified “stepwise” prosection-based laboratory cohort to supplement a dissection-based course. In this design, all students attended the same lectures, but those in the dissection-based cohort learned by performing regional dissections and students in the prosection-based cohort studied from those dissections. Prosection students thereby witnessed a “slow reveal” of structures throughout the course. This study compared the perceived course experiences, student approaches to learning, and academic performance between the two groups. Multiple linear regression analyses were used to isolate the effect of the laboratory environment on student approaches to learning and academic performance from demographic and situational covariates. Both groups reported positive course experience ratings and high average final grades that were not statistically dissimilar (P > 0.05), increased reliance on deep approaches to learning (P = 0.002), and decreased reliance on surface approaches to learning (P = 0.023). When controlling for covariates, participation in dissection had small but statistically significant positive associations with deep approaches to learning (P = 0.043), performance on laboratory oral assessments (P < 0.001), and average final grades (P = 0.039). Ultimately, both designs promoted meaningful learning and desirable performance outcomes, indicating that both dissection and stepwise prosection have the potential to facilitate high quality human anatomy instruction.
