Cadaveric Dissection in Relation to Problem-Based Learning Case Sequencing: A Report of Medical Student Musculoskeletal Examination Performances and Self-Confidence

Mercer University School of Medicine utilizes a problem-based learning (PBL) curriculum for educating medical students in the basic clinical sciences. In 2014, an adjustment was piloted that enabled PBL cases to align with their corresponding cadaver dissection that reviewed the content of anatomy contained in the PBL cases. Faculty had the option of giving PBL cases in sequence with the cadaveric dissection schedule (sequential group) or maintaining PBL cases out of sequence with dissections (traditional group). During this adjustment, students’ academic performances were compared. Students’ perception of their own preparedness for cadaveric dissection, their perceived utility of the cadaver dissections, and free-response comments were solicited via an online survey. There were no statistically significant differences when comparing student mean examination score values between the sequential and traditional groups on both multidisciplinary examinations (79.39 ± 7.63 vs. 79.88 ± 7.31, P = 0.738) and gross anatomy questions alone (78.15 ± 10.31 vs. 79.98 ± 9.31, P = 0.314). A statistically significant difference was found between the sequential group's and traditional group's (63% vs. 29%; P = 0.005) self-perceived preparedness for cadaveric dissections in the 2017 class. Analysis of free-response comments found that students in the traditional group believed their performance in PBL group, participation in PBL group and examination performance was adversely affected when compared to students with the sequential schedule. This study provides evidence that cadaveric dissections scheduled in sequence with PBL cases can lead to increased student self-confidence with learning anatomy but may not lead to improved examination scores.     

A faculty team works to create content linkages among various courses to increase meaningful learning of targeted concepts of microbiology

As research faculty with expertise in the area of host–pathogen interactions (HPI), we used a research group model to effect our professional development as scientific educators. We have established a working hypothesis: The implementation of a curriculum that forms bridges between our seven HPI courses allows our students to achieve deep and meaningful learning of HPI concepts. Working collaboratively, we identified common learning goals, and we chose two microorganisms to serve as anchors for student learning. We instituted variations of published active-learning methods to engage students in research-oriented learning. In parallel, we are developing an assessment tool. The value of this work is in the development of a teaching model that successfully allowed faculty who already work collaboratively in the research area of HPI to apply a “research group approach” to further scientific teaching initiatives at a research university. We achieved results that could not be accomplished by even the most dedicated instructor working in isolation.     

Pubertal development of the understanding of social emotions: Implications for education

Recent developmental cognitive neuroscience research has supported the notion that puberty and adolescence are periods of profound socio-emotional development. The current study was designed to investigate whether the onset of puberty marks an increase in the awareness of complex, or “mixed,” emotions. Eighty-three female participants (aged 9–16 years) were divided into three groups according to a self-report measure of puberty stage (early-, mid- and post-puberty). Participants were presented with emotional scenarios, and used four linear scales to rate their emotional response to each scenario. Scenarios were designed to evoke social emotions (embarrassment or guilt) or basic emotions (anger or fear), where social emotions are defined as those which require the representation of others' mental states. We measured the relative complexity or “mixedness” of emotional responses, that is, the degree to which participants reported feeling more than one emotion for a given scenario. We found that mixed emotion reporting increased between early- and post-puberty for social emotion scenarios, and showed no relationship with age, whereas there was no change in mixed emotion reporting for basic emotion scenarios across age or puberty groups. This suggests that the awareness of mixed emotions develops during the course of puberty, and that this development is specific to social emotions. Results are discussed in the context of brain development across puberty and adolescence, with speculation regarding the potential implications for education.     

TOTs: A time‐on‐task analysis of ethnic minority children in a multilingual nursery school

This paper presents a time‐on‐task analysis for a group of six 3‐year‐old children during their first term in a multilingual nursery school. The children are third‐generation British, born to families who are settled migrants. Data were collected using observation schedules specially designed to gather contextual data (Geertz, 1975), to describe the ways in which these young pupils spent their time in the nursery school. The children were observed on two separate occasions, on their first day in the nursery and then again 12 weeks later towards the end of their first term in formal education. Data analysis will be presented in the form of graphs to demonstrate the change in the patterns of time‐on‐task during the period of enculturation into the school environment. Findings differ from previous time‐on‐task analyses for monolingual children of a comparable age in a similar setting (Sylva et al., 1980).     

The I files,the truth is out there: science teachers’ constructs of inquiry

This article is concerned with the personal constructs of science teachers about inquiry in selected schools in the Yorkshire and the Humber region of England. While there is a large volume of existing literature which advocates the use of inquiry in the science classroom to enhance students' engagement with, and learning of science, relatively few of these studies represent teachers' voice. Therefore, we believe that it is important and distinctive to report teachers' constructs of inquiry and related concerns regarding its use in the science classroom. We identify the key constructs from 10 participating teachers and discuss these amongst a backdrop of policy implications for inquiry approaches in English secondary school science classrooms. Personal Construct Theory was used to underpin the study and frame data collection and analysis. Key findings show that the teachers identify an inquiry approach as being effective in stimulating students' independent learning and interest in science but issues such as time and confidence inhibit their deployment of inquiry approaches.     

Diagnosing the Poor Performance of Self‐worth Protective Students: A product of future outcome uncertainty,evaluative threat,or both?

Self‐worth protective students characteristically perform well on some occasions yet on other occasions they perform poorly. In this study, two accounts of the poor performance of self‐worth protective students are assessed. The first is that their poor performance is an outcome of evaluative threat. The second is that their poor performance is an outcome of future outcome uncertainty: a product of their uncertain global self‐esteem and uncertainty about the causes of achievement outcomes. Students high or low in self‐worth protection were exposed to either noncontingent success (creating future outcome uncertainty), noncontingent failure (evoking evaluative threat), or contingent success. Their ability to solve two tasks that involved a high degree of uncertainty was then assessed. Students high in self‐worth protection performed poorly following both noncontingent failure and noncontingent success, supporting the roles of both evaluative threat and future outcome uncertainty. The implications in terms of enhancing the achievement of students high in self‐worth protection are discussed.     

Education and Nationhood in Wales: An Historiographical Analysis

Throughout the centuries, a sense of national identity in Wales has manifested itself in a variety of ways – aspirations to statehood, a unique language, cultural distinctiveness, religious affiliation, sporting achievement and, most recently, political devolution. Educational institutions in myriad forms have reflected aspects of these manifestations and themselves shed some light on their nature. In turn, the historiography of education in Wales is itself a product of national, educational, social and scholarly preoccupations which both reflect the ideas and priorities of the time and shed some light on their nature and significance. It is the purpose of this article to make a preliminary exploration into some of these interactions and, in so doing, provide an introduction to some of the major secondary sources of information on Welsh education. To this end, the article outlines in very general terms outstanding landmarks in those elements of Welsh education since the early modern period which might be claimed to be distinctive and the way in which the historiography reflects and reinforces such claims. Although the article sketches the picture in the centuries from the Tudors to industrialisation, its main thrust, reflecting the historiography, is on the period since the nineteenth century when the England/Wales state took over the financing of the education of its citizens to an ever increasing extent. Within this period, there is particular emphasis on such episodes as the ‘Treason of the Blue Books’ in 1847, the Welsh Intermediate Education Act of 1889, the ‘Welsh Revolt’ following the Education Act of 1902 and the more subtle but steady devolutionary episodes evident in the twentieth century, culminating in the creation of the National Assembly for Wales in 1999. All have generated a range of secondary works which itself reflects the priorities of historians in a scholarly environment which, since the 1960s, has seen changes in approach to the study of history which have allowed historians of Welsh education to take their place in the mainstream of historical studies.     

Auditory delayed discriminations by the dolphin: Nonequivalence with delayed-matching performance

Working memory in a bottlenosed dolphin was tested in both indirect and direct auditory delayed-discrimination tasks in which a correct spatial response was conditional upon the nature of a preceding sound. In the indirect task, either one of two possible sounds was briefly presented. After a prescribed delay, the dolphin was cued to go either to a left-hand or right-hand paddle pair. Responses to the outer paddle of a pair were rewarded following sound A, and responses to the inner paddle of a pair were rewarded after sound B. In the direct delayed-discrimination task, only one paddle pair was used in each session. In both tasks, the delay interval between the discriminative sound stimulus and the opportunity for a spatial response was progressively increased over sessions until the animal failed to meet a specified performance criterion or self-terminated a session. Delay limits of about 30 and 60 sec were obtained in the indirect and direct tasks, respectively. The increase in delay limit in the latter task was attributable to the use of an overt mediational response during the longer delays. In both cases, however, the obtained delay limits fell considerably short of the 2- to 3-min limits obtained in auditory delayed-matching studies using the same test sounds and the same subject. The task differences indicate that working memory functions cannot depend upon memory of the predelay stimulus alone, but must be determined in part by additional processes.
