The Nature of Argumentation in School Mathematics and Physics Texts: The Case of Periodicity

The present study explores reasoning and argumentation in Greek mathematics and physics texts in specific topics related to the notion of periodicity. In our study, argumentation is taken as the sequence of the modes of reasoning (MsoR) that an author develops in a text when organizing and presenting new knowledge. Inductive content analysis was applied on 71 thematic units taken from 4 mathematics and 4 physics textbooks, and a coding system of categories and subcategories of MsoR was produced. Our analysis discerned 4 main categories of MsoR: empirical, logical-empirical, nomological, and mathematical; we argue that each mode of reasoning (MoR) plays a different role in conceptualizing aspects of periodicity. Analysis of the sequence of MsoR in two thematic units raised pragmatic considerations on the text understanding in relation to the scientific argumentation discourse and highlights ontological differences in the two subjects when ascending from observations to generalizations. Educational implications of the findings are discussed.     

Children’s Teleological Intuitions: What Kind of Explanations Do 7–8 Year Olds Give for the Features of Organisms, Artifacts and Natural Objects?

Research has shown that children usually provide teleological explanations for the features of organisms from a very early age (3?C4?years old). However, it is not clear if teleology is applied selectively for organisms, or if it is generally applied to other objects as well (artifacts and non-living natural objects). The present study examined whether 7?C8?year old students provided teleological explanations for particular organisms, artifacts and natural objects. We investigated whether children's familiarity with these objects influenced the types of explanations they gave. Finally, we also investigated correlations between 'teleology' and 'usefulness' in children's explanations. The results indicate that 7?C8?year olds are able to distinguish between living and non-living entities, as well as that they provide teleological explanations mostly for organisms and artifacts. This may have important implications for biological education, since teleological explanations in classrooms are likely to pose important conceptual obstacles to the development of a scientific understanding of evolution.     

Examining the effects of home literacy and numeracy environment on early reading and math acquisition

The present study examined how the home literacy and numeracy environment in kindergarten influences reading and math acquisition in grade 1. Eighty-two Greek children from mainly middle socioeconomic backgrounds were followed from kindergarten to grade 1 and were assessed on measures of nonverbal intelligence, emergent literacy skills, early math concepts, verbal counting, reading, and math fluency. The parents of the children also responded to a questionnaire regarding the frequency of home literacy and numeracy activities. The results of path analyses indicated that parents’ teaching of literacy skills predicted reading fluency through the effects of letter knowledge and phonological awareness. Storybook exposure predicted reading fluency through the effects of vocabulary on phonological awareness. Finally, parents’ teaching of numeracy skills predicted math fluency through the effects of verbal counting. These findings suggest that both the home literacy and the home numeracy environments are important for early reading and math acquisition, but their effects are mediated by emergent literacy and numeracy skills.     

Bullying and empathy: a short‐term longitudinal investigation

The aim of this study was to test the direction of effect in the relationship between bullying and empathy. The participants were 205 sixth‐grade students, randomly selected from urban and rural schools in Cyprus. A six‐month, two‐time‐point longitudinal design was used in which the participants completed the bullying subscale of the Revised Bullying and Victimisation Questionnaire (BVQ‐R) and the Basic Empathy Scale. The results of this study showed that bullying at Time 1 negatively predicted the affective component of empathy at Time 2. Moreover, children’s affective empathy at Time 1 negatively predicted bullying at Time 2. The results of this study indicate towards a reciprocal model of understanding the relationship between bullying and empathy.     

A study of the information seeking behaviour of hospital pharmacists: empirical evidence from Greece

Background: Hospital pharmacists need access to high‐quality information in order to constantly update their knowledge and improve their skills. In their modern role, they are expected to address three types of challenges: scientific, organizational and administrative, thus having an increased need for adequate information and library services. Objectives: This study investigates the information‐seeking behaviour of public hospital pharmacists providing evidence from Greece that could be used to encourage the development of effective information hospital services and study the links between the information seeking behaviour of hospital pharmacists and their modern scientific and professional role. Method: An empirical research was conducted between January and February 2010 with the development and distribution of a structured questionnaire. The questionnaire was filled in and returned by 88 public hospital pharmacists from a total of 286 working in all Greek public hospitals, providing a response rate of 31%. Results: The hospital pharmacists in Greece are in search of scientific information and, more particularly, pharmaceutical information (e.g., drug indications, storage, dosage and prices). The Internet and the National Organization of Medicines are their main information sources, while the lack of time and organized information are the main obstacles they have to face when seeking information. Conclusions: The modern professional role of hospital pharmacists as invaluable contributors to efficient and safer healthcare services may be further supported through the development of specialized libraries and information services within Greek public hospitals.     

Effects of Home Literacy,Parents' Beliefs,and Children's Task-Focused Behavior on Emergent Literacy and Word Reading Skills

We examined the effects of home literacy (shared book reading, teaching activities, and number of books), children's task-focused behavior, and parents' beliefs and expectations about their child's reading and academic ability on kindergarten children's (N = 61) phonological sensitivity and letter knowledge and on Grade 1 word reading. The results showed that, after controlling for nonverbal IQ and vocabulary, home literacy instruction prior to kindergarten, parents' beliefs about their children's reading ability, and children's task-focused behavior were significant predictors of two or more of the dependent variables. Storybook reading did not account for unique variance in any of the dependent variables.     

How physically literate are children today? A baseline assessment of Greek children 8-12 years of age

ABSTRACT

Developing Physical Literacy (PL) in children is considered a promising concept for establishing active lifestyle habits; yet research evidence is scarce. This study aimed at comprehensively assessing PL in 8-12-year-old Greek children. For that purpose, the Canadian Assessment of Physical Literacy (CAPL-2) was administered to 715 children (M age = 10.2, SD = 1.3 years). Analyses of variance were applied on participants’ total, domain and individual measures scores, examining potential gender and age differences; whereas, participants’ classification and proportion across CAPL-2 interpretive categories were computed. Results revealed that there were no practically important differences (η² < .14) between boys and girls or younger (grades 3 & 4) and older children (grades 5 & 6). Greek children presented insufficient levels of PL (their total score classified them into “progressing” PL level). CAPL-2 domains and individual measures scores showed that participants were highly motivated and felt confident to participate in physical activity (PA); however, they exhibited low PA as well as unsatisfactory physical competence, knowledge, and understanding to value and take responsibility for engagement in PA. Although further research is needed for a comprehensive picture of PL correlates, our findings highlight the need for providing Greek children with ample opportunities to enhance their PL.     

Exploring the validity of a teachers’ self-efficacy scale in five countries

The purpose of this article was twofold. The first purpose was to test the validity of the Teachers’ Sense of Self-Efficacy Scale (TSES) in five settings—Canada, Cyprus, Korea, Singapore, and the United States. The second purpose was, by extension, to establish the importance of the teacher self-efficacy construct across diverse teaching conditions. Multi-group confirmatory factor analysis was used to better understand the measurement invariance of the scale across countries, after which the relationship between the TSES, its three factors, and job satisfaction was explored. The TSES showed convincing evidence of reliability and measurement invariance across the five countries, and the relationship between the TSES and job satisfaction was similar across settings. The study provides general evidence that teachers’ self-efficacy is a valid construct across culturally diverse settings and specific evidence that teachers’ self-efficacy showed a similar relationship with teachers’ job satisfaction in five contrasting settings.
