Ageing and skills: The case of literacy skills

The relationship between ageing and skills is of growing policy significance due to population ageing, the changing nature of work and the importance of literacy for social and economic well‐being. This article examines the relationship between age and literacy skills in a sample of OECD countries using three internationally comparable surveys. By pooling the survey data across time we can separate birth cohort and ageing effects. In doing so, we find that literacy skills decline with age and that, in most of our sample countries, successive birth cohorts tend to have poorer literacy outcomes. Therefore, once we control for cohort effects, the rate at which literacy proficiency falls with age is much more pronounced than that which is apparent, based on the cross‐sectional relationship between age and literacy skills at a point in time. Further, in studying the literacy‐age relationship across the skill distribution in Canada we find a more pronounced decline in literacy skills with age at lower percentiles, which suggests that higher initial literacy moderates the influence of cognitive ageing.     

The Twelve Cranial Nerves of Christmas: Mnemonics,Rhyme, and Anatomy – Seeing the Lighter Side

Anatomy, has in history, been linked to helpful ways to remember structures, branches of nerves, structures passing through foramina, etc. Scalp is even a mnemonic in itself (S kin, C onnective tissue, A poneurosis, L oose areolar tissue, P ericranium). There has been concern by some educators that using mnemonics or rhymes promotes a surface approach to learning and is unhelpful in establishing long-term and meaningful deep learning. This article argues that mnemonics and rhyme can be used, in the appropriate way, at the right time, by students as an important learning strategy. That strategy can help lay a foundation of knowledge to be developed and later built upon, or simply recall information more easily. Mnemonics, like all information that is to be recalled, is consolidated by rehearsal. In examining the neuroanatomy of learning theories, it is therefore possible to suggest that when students begin to learn an area of anatomy, such as the cranial nerves, using a mnemonic or rhyme, it can help students remember the names and facilitate the engagement of the working memory processes assisting the student to build a construct for subsequent deeper layers of knowledge. Modern approaches to anatomy education involve a myriad of learning opportunities, but educators must assess the value of each one before recommending them to students. It appears that using mnemonics and rhyme is as valid today as it has been for centuries.     

What Does a Modern Anatomist Look like? Current Trends in the Training of Anatomy Educators

Anatomical sciences are foundational to the health professions, yet little is known about the qualifications of anatomy educators at the graduate and professional level in the United States. Moreover, there is concern that the number of qualified anatomy educators being trained may be insufficient to meet the growing demand posed by new and expanded programs in medicine and allied health specialties. The authors surveyed anatomists from across the country to (i) characterize the educational credentials of current anatomy educators and (ii) assess the perceived need for education-focused postdoctoral positions or formal mentorships to prepare anatomists for teaching-intensive faculty positions. To probe the survey responses more deeply, one-on-one interviews were conducted with eight individuals selected to represent a diverse sample of respondents in terms of institution, gender, and academic rank. Results indicate that 30–40% of educators at the graduate level and approximately 60% of those at the undergraduate level lack graduate coursework in histology, embryology, and neuroanatomy. Forty-five percent of respondents had completed a postdoctoral fellowship. Eighty-six percent replied “yes/maybe” to the question of whether an anatomy education postdoctoral fellowship would benefit doctoral graduates. The top 3 reasons for this recommendation were to (i) establish independent educational research, (ii) improve a publication record, and (iii) gain additional teaching experience. Notable weaknesses of education-focused postdoctoral training were related to finances, fear of exploitation, and undervaluing of teaching. Moving forward, postdoctoral fellowships and other forms of postgraduate training may represent a key strategy for training anatomists in the current educational climate.

Assessing the severity of behavior disorders: Rankings based on clinical and empirical criteria

School psychologists need to assess the severity of behavior disorders accurately to facilitate comprehensive diagnosis, to provide appropriate intervention, to enlighten research efforts, and to be in compliance with state and federal guidelines. Although clinicians in fields such as mental retardation categorize severity of behavior to make diagnostic and general treatment decisions, school psychologists rarely attempt to assess severity in any systematic or comprehensive way. The primary purpose of this study is to see how 92 practicing school psychologists rank 11 variables in their assessments of SED in school-age children. A secondary purpose is to examine the extent of school psychologists' reliance upon clinical and empirical criteria in assessing the severity of SED. It is concluded that school psychologists agree in their rankings of variables from most to least important and that they do not consider empirical criteria more important than clinically based criteria when assessing SED. Implications for practice are presented.     

On the Performance of Semi- and Nonparametric Item Response Functions in Computer Adaptive Tests

Large-scale assessments often use a computer adaptive test (CAT) for selection of items and for scoring respondents. Such tests often assume a parametric form for the relationship between item responses and the underlying construct. Although semi- and nonparametric response functions could be used, there is scant research on their performance in a CAT. In this work, we compare parametric response functions versus those estimated using kernel smoothing and a logistic function of a monotonic polynomial. Monotonic polynomial items can be used with traditional CAT item selection algorithms that use analytical derivatives. We compared these approaches in CAT simulations with a variety of item selection algorithms. Our simulations also varied the features of the calibration and item pool: sample size, the presence of missing data, and the percentage of nonstandard items. In general, the results support the use of semi- and nonparametric item response functions in a CAT.     

Assessing severity in behavior disorders: Empirically based criteria

School psychologists are routinely required to make judgments about the severity of behavior disorders in children. While federal law demands that a child exhibit an emotional problem “to a marked degree,” school psychologists are given few clearcut guidelines for making judgments about the severity of students' adjustment problems. The purpose of this paper is to present a list of empirically based criteria for assessing the severity of behavior disorders in children. To this end, research on major behavior disorders in children of interest to school psychologists is reviewed.
