The Contribution of RAN Pause Time and Articulation Time to Reading Across Languages: Evidence From a More Representative Sample of Children

We examined the relationship between rapid automatized naming (RAN) components—articulation time and pause time—and reading fluency across languages varying in orthographic consistency. Three hundred forty-seven Grade 4 children (82 Chinese-speaking Taiwanese children, 90 English-speaking Canadian children, 90 Greek-speaking Cypriot children, and 85 Finnish-speaking children) were assessed on RAN (colors and digits) and reading fluency (word reading efficiency and text reading speed). The results showed that articulation time accounted for more unique variance in reading in the alphabetic orthographies than in Chinese, and pause time for more unique variance in reading in Chinese than in alphabetic orthographies. If automaticity in RAN is manifested with a higher contribution of articulation time to reading fluency than pause time and with a strong relationship between articulation time and pause time, then our findings suggest that automaticity in RAN is reached earlier in alphabetic orthographies than in Chinese.     

Development of an Instrument for Measuring Learner–Teacher Transactional Distance

An instrument was developed to assess the perceived learner–teacher transactional distance in the context of the Hellenic Open University and to provide psychometric evidence of reliability and validity of the interpretation of the scores derived from the scale. First, an elicitation study gathered information on students’ beliefs and feelings about their teachers’ behavior. Two dimensions of learner–teacher transactional distance, namely, co-understanding and awareness, were revealed. Then, an item pool was developed and the preliminary questionnaires (one for each dimension) were field tested on 60 postgraduate students who commented on their clarity. Reliability and validity were then tested using exploratory and confirmatory factor analysis with two samples of 220 and 201 postgraduate students. The confirmatory factor analysis results indicated good model fit for the dimensions of co-understanding and awareness. Univariate F tests showed no significant difference between males and females for (a) co-understanding of cognitive skills and aptitudes, (b) co-understanding of emotional state, (c) awareness of cognitive skills and aptitudes, and (d) awareness of emotional state. A final questionnaire included ten items for the co-understanding dimension and fifteen items for the awareness dimension.     

The impact of national educational policies on student achievement: a European study

This paper investigates the impact of national policies for improving teaching and the school learning environment (SLE) on student achievement. In each participating country (i.e., Belgium/Flanders, Cyprus, Germany, Greece, Ireland, and Slovenia), a sample of at least 50 schools was drawn and tests in mathematics and science were administered to all Grade 4 students (N = 10,742) at the beginning and end of school year 2010–2011. National policies were measured through (a) content analysis of policy documents, (b) interviews with policymakers, and (c) head-teacher questionnaires. Multilevel analyses revealed that most aspects of national policies for teaching and SLE were associated with student achievement in each subject irrespective of the source of data used to measure them. Implications are, finally, drawn.     

The role of achievement strategies on literacy acquisition across languages

We examined the importance of children’s achievement strategies in different literacy outcomes in three languages varying in orthographic consistency: Chinese, English, and Greek. Eighty Chinese-speaking Taiwanese children, 51 English-speaking Canadian children and 70 Greek children were assessed on measures of phonological awareness, rapid automatized naming, reading fluency, and spelling. The children’s use of a task-focused versus task-avoidant achievement strategy in the classroom context was rated by their teachers. The results indicated that the teacher-rated task-focused behavior was a significant predictor of spelling and to a lesser extent of reading fluency and that its effects were comparable across languages.     

Assessment of energy expenditure in children using the RT3 accelerometer

The aim of this study was to evaluate the utility of the RT3 accelerometer in young children, compare its accuracy with heart rate monitoring, and develop an equation to predict energy expenditure from RT3 output. Forty-two volunteers (mean age 12.2 years, s = 1.1) exercised at two horizontal and graded walking speeds (4 and 6 km.h(-1), 0% grade and 6% grade), and one horizontal running speed (8 km.h(-1), 0% grade), on a treadmill. Energy expenditure and oxygen consumption (VO2) served as the criterion measures. Comparison of RT3 estimates (counts and energy expenditure) demonstrated significant differences at 4, 6, and 8 km.h(-1) on level ground (P < 0.01), while no significant differences were noted between horizontal and graded walking at 4 and 6 km.h(-1). Correlation and regression analyses indicated no advantage of vector magnitude over the vertical plane (X) alone. A strong relationship between RT3 estimates and indirect calorimetry across all speeds was obtained (r = 0.633-0.850, P < 0.01). A child-specific prediction equation (adjusted R2 = 0.753) was derived and cross-validated that offered a valid energy expenditure estimate for walking/running activities. Despite recognized limitations, the RT3 may be a useful tool for the assessment of children's physical activity during walking and running.     

Reading and Spelling Development Across Languages Varying in Orthographic Consistency: Do Their Paths Cross?

We examined the cross-lagged relations between reading and spelling in five alphabetic orthographies varying in consistency (English, French, Dutch, German, and Greek). Nine hundred and forty-one children were followed from Grade 1 to Grade 2 and were tested on word and pseudoword reading fluency and on spelling to dictation. Results indicated that the relations across languages were unidirectional: Earlier reading predicted subsequent spelling. However, we also found significant differences between languages in the strength of the effects of earlier reading on subsequent spelling. These findings suggest that, once children master decoding, the observed differences between languages are not related to the direction of the effects but to the strength of the effects from reading to spelling. Theoretical and practical implications are discussed.     

Classroom assessment in Greek primary schools

ABSTRACT

This paper briefly presents some of the main findings concerning the implementation of assessment in Greek primary classrooms, from a study which explored the relation between teaching, learning and assessment in the primary classroom. It examines the assessment practices used; the purposes teachers attempted to fulfil when assessing; and the content of these assessments. The broader aim of the study was to present a general picture of assessment procedures in a typical Greek primary classroom. Classroom observations, a questionnaire and informal interviews with observed teachers and pupils provided rich data regarding teachers’ practices and their views of assessment.     

Bridging distant technological domains: A longitudinal study of the determinants of breadth of innovation diffusion

The diffusion of innovations is identified as an important aspect of technological and social change. Innovations diffuse through segmented networks of knowledge that limit the flow of knowledge from any one technological domain to any other. Despite this segmentation, some organizations are capable of developing pieces of knowledge that overcome these limitations. Within this context, we develop four hypotheses regarding specific R&D strategies that affect a firm’s ability to develop inventions that diffuse beyond the firm’s technological boundaries. Specifically, we examine how a firm's scientific intensity, technological collaborations, technological diversity, and internal focus impact breadth of innovation diffusion. We use two of the main determinants of innovation diffusion, namely, the relative advantage and the observability, as theoretical mechanisms to build our arguments. We empirically test our hypotheses on longitudinal data from the industries of pharmaceuticals, biotechnology, and chemicals. Our findings show that the extent to which the knowledge embedded in a firm’s inventions diffuses in distant technological areas is positively related to the firm’s scientific intensity and to its extent of collaboration, but it is negatively related to its technological diversity.     

Football fan culture and politics in modern Greece: the process of fandom radicalization during the austerity era

The article explores the intersection between politics and football focusing on political activism in football fandom starting from its origin in late 1970s to the contemporary mass protests against austerity policies. The analysis focused on ideological conflicts between fascist and anti-fascist fans within football lifeworlds and the ways organized fans use current political circumstances to negotiate and re-interpret their identities. In the context of the Greek economic crisis, the intersection between fandom and political activism as well the newly emerged political formations that come from football elites and big business signify an important turn towards the ‘footballization’ of Greek politics. This trend reflects the growing disillusionment of Greeks towards a discredited political system and their anxious seeking of some savours come from outside the politics, as a magical solution to the social pressures and deadlocks of a society in crisis.
