Associations of Number Line Estimation With Mathematical Competence: A Meta‐analysis

The number line estimation task is widely used to investigate mathematical learning and development. The present meta‐analysis statistically synthesized the extensive evidence on the correlation between number line estimation and broader mathematical competence. Averaged over 263 effect sizes with 10,576 participants with sample mean ages from 4 to 14 years, this correlation was r = .443. The correlation increased with age, mainly because it was higher for fractions than for whole numbers. The correlation remained stable across a wide range of task variants and mathematical competence measures (i.e., counting, arithmetic, school achievement). These findings demonstrate that the task is a robust tool for diagnosing and predicting broader mathematical competence and should be further investigated in developmental and experimental training studies.     

The impact of early metalinguistic competencies and memory capacity on reading and spelling in elementary school: Results of the Munich Longitudinal Study on the Genesis of Individual Competencies (LOGIC)

This paper reports on a longitudinal study dealing with the development of literacy in young children. A total of 163 children were first tested during their last year in kindergarten using a variety of tasks that tapped phonological processing, memory capacity, early literacy, and intelligence. Children’s word decoding, reading comprehension, and spelling skills were assessed in elementary school several years later. As a main result, all of the predictor domains had a significant impact on the acquisition of literacy in elementary school, although the contribution of each domain differed as a function of the criterion measure. An attempt to identify children-at-risk using a kindergarten screening test provided encouraging results. Nonetheless, it was shown that whereas group predictions of reading and spelling performance can be quite accurate, the individual prognosis of school problems is far from perfect.

he Challenges of Teaching Good Information Processing to Learning Disabled Students

A MODEL of good information processing is sketched, describing how metacognitive knowledge influences strategy selection and use. Three factors pose particular problems for learning disabled students as they attempt to acquire metacognitive knowledge and to use study strategies productively: neurological impairments; deficiencies in general world knowledge; and negative beliefs, attitudes, and styles that limit self‐efficacy. Creating an educational atmosphere that explicitly builds conceptual (domain‐specific) knowledge and teaches positive beliefs about learning potential is essential in promoting metacognitively‐oriented instruction.     

Wege in die Wissenschaft

Zusammenfassung Dieser Artikel besch?ftigt sich mit einem Themengebiet, das in der erziehungswissenschaftlichen Wissenschafts-, Hochschul-und Berufsforschung bislang kaum analysiert worden ist. Unter Bezug auf die Ergebnisse einer schriftlichen Befragung von rund 3.800 Absolventen erziehungswissenschaftlicher Hauptfachstudieng?nge (Diplom, Magister) in ganz Deutschland wird die Frage untersucht, wie gro? die Gruppe der Studierenden aus diesen Studieng?ngen ist, die sich einige Jahre nach dem Studienabschluss im Arbeitsfeld Hochschule und Forschung beruflich platzieren kann bzw. promoviert, durch welche Merkmale diese Gruppe gekennzeichnet ist und welche Bedingungsfaktoren den Weg in die Wissenschaft beeinflussen. Nach einem überblick über den bisherigen Stand der Forschung und der Darstellung zentraler Resultate des Diplom-und Magister-Surveys zum Weg in die Wissenschaft werden abschlie?end einige Konsequenzen diskutiert, die sich aus den Befunden für eine Reform der bisherigen Hauptfachstudieng?nge bzw. für die zukünftige Gestaltung neuer Studieng?nge mit Blick auf eine Verbesserung der Nachwuchsf?rderung für das Fach Erziehungswissenschaft ergeben.

Summary Paths into Science: The Results of a National Survey of Graduates from Diplom and Magister Programs in Educational Science This article examines a topic which has hardly been dealt with in the field of Educational Science. A survey of around 3,800 graduates of Educational Science in both Diplom and Magister programs in Germany asked what proportion of graduates went on to work or commence a Ph.D. in higher education. It also investigated the characteristics of such graduates and the conditions which determined their path into science. Following an overview of preceding research in this area and a presentation of the central results of the survey, the consequences of the findings for a reform of courses and an improvement in the training of academics in the field of Educational Science will be discussed.

     

Sensory Processing in Rhesus Monkeys: Developmental Continuity,Prenatal Treatment,and Genetic Influences

Neonatal sensory processing (tactile and vestibular function) was tested in 78 rhesus macaques from two experiments. At ages 4–5 years, striatal dopamine D₂ receptor binding was examined using positron emission tomography. At ages 5–7 years, adult sensory processing was assessed. Findings were: (a) prenatal stress exposure yielded less optimal neonatal sensory processing; (b) animals carrying the short rh5‐HTTLPR allele had less optimal neonatal sensory scores than monkeys homozygous for the long allele; (c) neonatal sensory processing was significantly related to striatal D₂ receptor binding for carriers of the short allele, but not for animals homozygous for the long allele; and (d) there was moderate developmental continuity in sensory processing from the neonatal period to adulthood.     

Sensory processing disorder in a primate model: evidence from a longitudinal study of prenatal alcohol and prenatal stress effects

Disrupted sensory processing, characterized by over- or underresponsiveness to environmental stimuli, has been reported in children with a variety of developmental disabilities. This study examined the effects of prenatal stress and moderate-level prenatal alcohol exposure on tactile sensitivity and its relationship to striatal dopamine system function in thirty-eight 5- to 7-year-old rhesus monkeys. The monkeys were from four experimental conditions: (a) prenatal alcohol exposed, (b) prenatal stress, (c) prenatal alcohol exposed + prenatal stress, and (d) sucrose controls. Increased D(2) receptor binding in the striatum, evaluated using positron emission tomography neuroimaging, was related to increased withdrawal (aversion) responses to repetitive tactile stimuli and reduced habituation across trials. Moreover, prenatal stress significantly increased overall withdrawal responses to repetitive tactile stimulation compared to no prenatal stress.     

Von der Hauptschule in die Sekundarstufe II ein aufstiegsbedingter Abstieg

Efforts to break the link between the school type attended and the qualification awarded are seen as an important step towards more permeability and upward mobility of Germany’s tracked secondary school system. Results from a biographical longitudinal study, which explored the transition from the low-ability school type Hauptschule to upper secondary education in general and vocational Gymnasium (grammar schools) yet show that from the students’ perspective, it is very challenging to take on the transition from lower-level ability to upper-level secondary school types , even though this may be institutionally possible, and desirable from an educational political perspective. For the students, this transition brings along the experience of severe degradation     

‘The rules above the bed’: academic language and learning as hospitality

ABSTRACT

In times of widening participation, Australian universities trade on notions of diversity, framing themselves as hospitable places of access and inclusion. In this space, Academic Language and Learning (ALL) practitioners may be seen as extending the welcome of the university through practices aimed at addressing students’ diverse needs. These include identifying students ‘at-risk’ of failure and attrition, conducting one-to-one appointments, and embedding academic literacies by team-teaching within disciplines. In this paper, we reflect on these practices through the lens of Derrida’s notion of hospitality, drawing on key themes such as the constitutive power relationships of hospitality, the aporia between conditional and unconditional hospitality, and hospitality as an ethics of difference and openness to the ‘arrival of the new’. For each of the explored practices, we problematise the institutionalised framing of ALL practitioners as hosts in benevolent universities providing an unreserved welcome to the student ‘foreigner’. We examine the practice of identifying students-at-risk and question a conditional hospitality that risks closing the door on the unforeseeable that students may bring. Our reflection on the managerially devalued one-to-one appointments highlights hospitality as ethics, with each appointment presenting a crisis of choice in responsibly welcoming student difference. Team-teaching exposes the ambiguity of the ALL practitioner ‘being at-home’ in embedded contexts while presenting the possibility for disrupting established roles and practices. Engaging with Derrida’s hospitality thus allows us to uncover power dynamics shaping the role of ALL practitioners and offers the possibility of ethical responsiveness to student difference and a radical opening to the new.     

A cross-cultural comparison of German and Canadian student teachers’ assessment competence

ABSTRACT

Teachers’ competence in educational assessment is a key feature in teacher professionalism. Understanding of assessment competence has evolved from the learning of technical skills in assessment to a context-dependent, socially defined understanding encompassing a multitude of approaches to assessment. Thus, a holistic approach to assessment competence is used in this research to specifically consider the role of education culture on assessment competence. In particular, we compared Canadian and German student teachers with regard to their self-rated competence in, and approaches towards, educational assessment. While structural analysis revealed that the overall dimensions in which assessment is perceived do not depend on culture, ANOVAs pointed at some differences between the two countries, particularly concerning assessment purposes and approaches to fairness.
