Emergent literacy activities in the final preschool year in the German federal states of Bavaria and Hesse

Emergent literacy activities are considered to be important for promoting children’s emergent literacy skills. However, little research exists, especially in Germany, regarding how often such activities occur and in what context. The purpose of this study was to determine the extent of emergent literacy activities occurring in the final preschool year, and their dependence on structural characteristics. Ninety-six children (mean age = 5.9) from 50 preschools in two German federal states were observed in their final preschool year. Results show that emergent literacy activities relating to print materials play a minor role, whereas activities involving oral language play a major role, compared with other activities in children’s preschool experience. Results also indicate a significant link between child-related, family and distal characteristics (i.e. geographic location and federal state affiliation) and the frequency of emergent literacy activities.     

A study on a set of drawings by Parmigianino: integration of art-historical analysis with imaging spectroscopy

Due to the extreme fragility of paper-based artefacts, few techniques are available for scientific investigation and characterisation of ancient drawings or paper-based artefacts. Image reflectance spectroscopy represents an almost unique tool for scientific analysis on precious drawings, for which even micro-invasive techniques of analysis cannot be used. Indeed, beside the high fragility of the support, drawings and graphical works are typically characterised by a very limited number of artistic materials, which in principle could give information on the work of art. In this paper an interdisciplinary study on a set of drawings by Parmigianino (1503–1540), selected from the collection of the Uffizi Gallery in Florence, is presented. Non-invasive measurements of image spectroscopy (IS) have been employed to support the work of art-historians in the critical re-examination and interpretation of the graphical work of the artist. The multispectral analysis has been carried out over the extended spectral region (400–1700 nm), in order to provide simultaneous indications both on the pictorial materials and on possibly underlying hatches. The data processing has been performed by means of Principal Component Analysis (PCA) and the elaboration of each case has been addressed to specifically respond to questions related to the art-historical problem.     

Deleterious effects of obesity on physical fitness in pre-pubertal children

The prevalence of obesity in children has increased dramatically during the past decades in Europe and understanding physical fitness and its components in children is critical to design and implement effective interventions. The objective of the present study was to analyse the association between physical fitness (aerobic, speed, agility, power, flexibility and balance) and body mass index (BMI) in pre-pubertal children. A total of 2411 healthy schoolchildren (7–11 years) participated in this study. Anthropometric characteristics and body composition were assessed by skinfold thickness. Physical fitness was measured by nine physical fitness tests: endurance running, 20 m running speed, agility, handgrip strength, standing long jump and squat jump, sit and reach, medicine ball forward throw and static balance. No relevant differences were observed between boys and girls regarding anthropometric characteristics, body composition and physical fitness. However, overweight and obese children showed significantly lower physical fitness levels in endurance running, speed and agility (mean: +18.8, +5.5 and +14.5% of time to complete tasks, respectively), lower limb power normalised to body mass (?23.3%) and balance tests (number of falls: +165.5%) than their normal weight counterparts. On the other hand, obesity did not affect handgrip, throwing and flexibility. In conclusion, increased BMI was associated with lower performance capabilities limiting proper motor skill development, which directly affects the ability of children to take on sports skills. Actions undertaken to promote children's wellness and fitness should be prioritised and introduced early in life with the aim of enhancing physical fitness as well as preventing overweight and obesity.     

Implementing process-based instruction in regular university teaching: Conceptual,methodological and practical issues

This paper reports an experimental field study aimed at examining whether a process-oriented form of instruction (combining program planning and interactive teaching) which produced outstanding results when implemented by a tutor/researcher (see Volet, 1991) could be used successfully by regular university tutors given detailed guidelines but minimal training. A second aim of the study was to establish the respective contribution of the two sub-components of the instructional package. The results of the study were inconclusive and raise a number of conceptual, methodological and practical issues. As in the initial study, experimental students were more satisfied with their learning and for those who had the choice, more inclined to undertake further studies in computing but the intervention did not affect students’ achievement. The results of the study are discussed in relation to the earlier work, and suggestions are made for bridging the gap between educational research and educational practice in higher education.     

The effect of external representation on constructing computer models of complex phenomena

Computer modeling – creating executable modelsof science domains – has been recognized as animportant teaching method. Still not much isknown about the factors making modelingenvironments effective in use. We investigatethe effect of different externalrepresentations on the construction of computermodels. Representations can significantlyinfluence the processes of modeling. In orderto find the specific benefits of two differentrepresentations, we compare dyads working on acollaborative modeling task using a text-basedmodel representation, in which correctequations are required to make the model run,with others using a graphical representation,in which the model is built by qualitativelylinking variables. The learners, secondaryschool students and modeling novices, workedwith the representations on a task in thedomain of physics. Results indicate that thetwo representations induce differentbehaviours, which are appropriate for differentphases of the modeling process.     

Teacher education research and education policy-makers: an Australian perspective

As teacher educators, we want our research to be influential in contributing to educational policy and practice, but there remains little understanding about ways in which teacher educators might more productively engage with each other and policy-makers so as to maximise their research impact. Drawing on an empirical study and policy document analysis, this paper seeks to foster a generative ‘researcher-policy-maker dialogue’ by understanding more about policy-makers’ perspectives of what shapes their decision-making and the current role of research evidence in those decisions. Using a research utilisation theoretical framework and discourse analysis, data revealed various factors that served as barriers or enablers to using research in making education policy decisions. Results indicated that policy-makers largely position research as key to solving their policy problems. As such they sought better communication strategies to utilise research findings in a timely, free and publicly accessible, user-friendly manner. Overall, they called for a greater dialogue and engagement at all stages of the policy process and criticised what they perceived as a ‘fly in-fly out’ research approach. Recommendations suggest new collaborative approaches and genres are needed for the teacher education research community to have a greater impact in influencing policy.     

Retrospective cytological evaluation of indeterminate thyroid nodules according to the British Thyroid Association 2014 classification and comparison of clinical evaluation and outcomes

The cytology of 130 indeterminate nodules (Thy 3) was retrospectively reviewed according to the British Thyroid Association 2014 classification. Nodules were divided into Thy 3a (atypical features) and Thy 3f (follicular lesion) categories. Histology was available as a reference for 97 nodules. Pre-surgical evaluations comprised biochemical tests, color-Doppler ultrasonography (US), semi-quantitative elastography-US (USE), contrast-enhanced US (CEUS), and mutation analysis from cytological slides. Thyroid malignancy was the final diagnosis for 19% of surgically-treated nodules. No statistically significant difference in the risk of malignancy was found between Thy 3a (26%) and Thy 3f (14%) nodules. Histology of the Thy 3a and Thy 3f nodules showed a higher incidence of Hurtle cell adenomas in Thy 3f (29%) than in Thy 3a (3%) nodules (P=0.01). The only pre-surgical difference concerned the BRAF V600E mutation, which was positive in some Thy 3a but not in any Thy 3f nodules (P=0.04). Receiver-operating characteristic (ROC) analysis was used to obtain cut-off values from US (score), USE (ELX 2/1 strain index), and CEUS (time-topeak index and peak index) data. The cut-off values were similar for Thy 3a and Thy 3f nodules. Data showed that malignancy can be suspected if the US score is >2, ELX 1/2 strain index >1, time-to-peak index >1, and peak index <1. In a sub-group of 24 revised nodules (12 Thy 3a and 12 Thy 3f) with histology as a reference, the diagnostic power of cumulative pre-surgical analysis by means of US, USE, and CEUS showed high positive and negative predictive values (83% and 100%, respectively) for the presence of malignancy in Thy 3a and Thy 3f nodules. In conclusion, in our series of revised Thy 3 nodules, malignancy was low and displayed no significant differences between Thy 3a and Thy 3f categories. The use of cut-offs based on histology as a reference could reduce surgery. Our data support the conviction that, in mutation-negative Thy 3a and Thy 3f nodules, observation should be the first choice when not all instrumental results are suspect.     

Group work at university: significance of personal goals in the regulation strategies of students with positive and negative appraisals

This paper examines the mediating role of students’ goals in group work at university. Research on cooperative and collaborative learning has provided empirical support for the cognitive, motivational and social benefits of group work but the antecedents of motivation and ongoing management of emerging motivational and socio‐emotional issues have received less attention. A theory of self‐regulation that incorporates students’ personal goals and perceptions of context, combined with a sociocultural perspective on co‐regulation of individuals and contexts, can help understand why and how some groups resolve their social challenges while others are less successful. An empirical study highlighted the mediating role of students’ goals in their appraisals of group assignments, perceptions of various aspects of the contexts, and in turn regulation strategies to achieve their goals. Qualitative differences were found in the regulation strategies of students with positive and negative appraisals.     

Action research in science education – an analytical review of the literature

Action research is suggested as a way to engage teachers in curriculum development and the betterment of teaching practices in schools based on educational research activities. As in other educational domains, action research in science education is employed with both aims to better understand and develop teaching practices and to contribute to teacher continuous professional development. A variety of methodological approaches using action research in science education exists, from more technical toward more emancipatory interpretations. The range of educational settings and goals for which action research is performed is also quite broad. The purpose of this analytical review of the international available literature is to provide an overview of the main aspects in applying action research in science education.     

Early Childhood Education and Care for Children with Disabilities: Facilitating Inclusive Practice*

In this case study, a co-operative inquiry process was used to facilitate the expansion of inclusive early childhood education and care practices in a rural community in the Midwest. A university and a community researcher first engaged in interviews and site visits, during which they learned how a three-member inclusion team of early care and education professionals initiated changes in practice from self-contained to inclusive special education and therapy. Key practices included responding to families’ priorities, changing roles, and providing integrated services and support for children’s successful transitions into Kindergarten. The second part of the research consisted of action planning during focus groups and community meetings, which resulted in social recognition from the school district, technical assistance through state improvement grant funding, and better preschool options for young children with disabilities. *We gratefully acknowledge partial funding of this research by the Dean's Office at the University of Wisconsin-Whitewater and State Improvement Grant funding by the Department of Public Instruction.
