DO UNIVERSITIES HELP THE ECONOMY? THE CASE OF THE DEMOCRITUS UNIVERSITY OF THRACE

This article analyses the relationship between a dispersed‐campus regional university in Greece, the Democritus University of Thrace, and the local economy. The author is led to conclude that little connection or balance exists between the financial consequences of the operation of the university and regional development. The presence of the university has increased consumption without having created new jobs or research areas linked to the social structure or to the economic needs of the region.

     

Complex and Non-Regular Shapes: Their Evolution in Greek Textbooks (1749–1971)

Current research suggests that problem solving concerning complex and non-regular shapes can enhance the acquisition of the concept of area. Despite the fact that this topic was always present in Greek mathematical textbooks it disappeared in the modern ones. In this paper we deal with the way the specific topic has been presented for a long period (since 1749 until 1971). We describe the methods that known Greek scholars proposed for the calculation of the area of complex and non-regular shapes and how the content of the relevant problems varies through these three centuries according to the social circumstances that affected the philosophy of the educational system.     

Exploring the association between teachers’ perceived student misbehaviour and emotional exhaustion: the importance of teacher efficacy beliefs and emotion regulation

The purpose of this study is to examine the relationship between teachers’ perceived student misbehaviour and emotional exhaustion, and the role of teacher efficacy beliefs (related to handling student misbehaviour) and emotion regulation in this relationship. Additionally, we examined teacher turnover intentions in relation to emotional exhaustion. Data were collected from 610 elementary, middle‐ and high‐school teachers using an online survey. Results indicate that despite the significant direct effect between the two emotion regulation strategies (cognitive reappraisal, expressive suppression) on emotional exhaustion, both strategies failed to show a mediating effect between perceived student misbehaviour and emotional exhaustion. However, teacher efficacy in handling student misbehaviour was found to mediate the relationship between perceived student misbehaviour and emotional exhaustion. In turn, a significant relationship was found between emotional exhaustion and turnover intentions. Furthermore, teacher perception of student misbehaviour was found to have a considerable indirect effect on teacher turnover intentions. Findings signify the importance of developing strategies that enhance teachers’ situation‐specific efficacy beliefs.     

Children’s orthographic representations in English and Greek

Two experiments were conducted to compare the development of orthographic representations in children learning to read English and Greek. Nonsense words that either shared both orthography and phonology at the level of the rhyme with real words (comic-bomic), phonology only (comic-bommick), or neither (dilotaff) were created for each orthography. Experiment 1 compared children’s reading of bisyllabic and trisyllabic nonsense words likebomic vs.bommick, taffodil vs.tafoddyl, and found a significant facilitatory effect of orthographic rhyme familiarity for English only. Experiment 2 compared children’s reading of trisyllabic nonsense words that either shared rhyme phonology with real words (tafoddyl) or did not (dilotaff). Significant facilitation in reading accuracy was found for shared rhyme phonology in English, with a significant speed advantage in Greek. These results are interpreted in terms of the level of phonology that is represented in the orthographic recognition units being developed by children who are learning to read more and less transparent orthographies.     

An adaptive mechanism for Moodle based on automatic detection of learning styles

This paper proposes an automatic approach that detects students’ learning styles in order to provide adaptive courses in Moodle. This approach is based on students’ responses to the ILS and the analysis of their interaction behavior within Moodle by applying a data mining technique. In conjunction to this, an adaptive mechanism that was implemented in Moodle is presented. This adaptive mechanism builds the user model based mainly on the proposed approach for automatic detection of learning styles in order to adapt the presentation and the proposed navigation to students’ different learning styles and educational objectives. An evaluation study was conducted to evaluate the proposed approach for automatic detection of learning styles and the effect of the adaptive mechanism. Two groups of students were formed, namely the experimental and the control. The first had access to a Moodle course that automatically detected their learning styles and exploited the adaptive mechanism, whilst the second had access to the standard version of a Moodle course. The results were promising since they indicated that our proposed approach for automatic detection of learning styles attained adequate precision compared to other works, even though the patterns considered are less complex. Additionally, the results indicated that the adaptive mechanism positively affected students’ motivation and performance.     

Enhancing student teachers’ epistemological beliefs about models and conceptual understanding through a model-based inquiry process

In this study we present the structure and implementation of a model-based inquiry teaching–learning sequence (TLS) integrating expressive, experimental and exploratory modelling pedagogies in a cyclic manner, with the aim of enhancing primary education student teachers’ epistemological beliefs about the aspects, nature, purpose and change of models as well as their conceptual understanding of light phenomena related to properties of optical fibres. The subjects were 16 prospective primary teachers involved in modelling activities, employing both hands-on experiments and computer modelling activities, based on the application of the ray model. Student teachers were tested before and after the implementation of the TLS by semi-structured interviews and a written questionnaire. Results show that before the TLS most students adopted epistemologically naïve realistic beliefs about models, whereas after the TLS there was an overall significant transition from naïve to more sophisticated epistemological beliefs, as well as significant improvements in their conceptual knowledge about light phenomena. Nevertheless, the relation between epistemological beliefs and conceptual understanding seems to be aspect-dependent, so our evidence suggests that more educational effort is required in order to establish a coherent relationship between them.     

Creative approaches to staff development: global education in ITE in The Gambia

The elements of global education should be at the heart of all learning and teaching. In ITE we often protect ‘our subject’ in the belief that it should have more prominence in the curriculum and more teaching time in school. In this article a group of ITE tutors comment on their learning about global education and its inclusion in their subject following a study trip, with students and teachers, to The Gambia. A truly cross-curricular strand develops and ideas within subjects are matched to key concepts of global education. An experiential model of tutor CPD evolves which includes personal challenge of values and attitudes.     

Hyperhydration using different hydration agents does not affect the haematological markers of the athlete biological passport in euhydrated volunteers

ABSTRACT

Athlete Biological Passport (ABP) is an indirect approach, implemented by WADA, aimed at detecting blood manipulation based on abnormal changes in haematological markers. Cases report the use of hyperhydration as masking method during anti-doping urine sample collection which could potentially mask suspicious fluctuations on ABP profiles. This study investigated the hyperhydration effect on haemoglobin concentration, reticulocyte percentage and OFF-hr score (an algorithm based on haemoglobin concentration and reticulocyte percentage), with and without recombinant human erythropoietin (rHuEPO) administration. A five-week clinical study performed; Baseline and rHuEPO Phase. Water and a sports drink were used as hyperhydration agents. To examine the hyperhydration effect on the normal ABP profile per volunteer, hyperhydration was implemented at 0, 24 and 48 hours during the baseline. During the rHuEPO phase, volunteers received Epoetin beta (3000 IU) with hyperhydration to be implemented at 0, 24 and 48 hours after drug administration. Blood and urine samples were collected and analysed according to WADA guidelines. No significant effect on ABP markers was observed due to hyperhydration at any time during the study. Pre- and post-hyperhydration data were not statistically different compared to individual baseline data. In conclusion, hyperhydration does not affect the ABP haematological markers under the examined conditions.     

Lecturers＇ attitudes on electronically supported pre-lecturing material for intensive programs： A case study

In 2006 and 2008, two large trans-national residential summer schools on conservation science were organized as intensive programs. Learners were not only second/third cycle students in both exact sciences and humanities, but further practicing restorers; consequently their educational background, and even their way of approaching scientific problems, were very diversified, and evaluation of the feedback brought about an urgent need for leveling knowledge and skills. The 3rd summer school, scheduled for July 2009, is addressing the issue by offering self-paced preparatory material authored by the lecturers, and obeying patterns that satisfy the specific needs of both an e-learning environment and a homogenization procedure. Before being offered to the attendees, the pre-lecturing material underwent an interim evaluation concerning its conformity to the Bologna process concepts, as well as to generally accepted methodologies for electronically supported distance learning. Furthermore, teachers were asked on their attitudes towards the proposed scheme. Evaluation of the answers permits drawing conclusions on how far lecturers are capable of and/or willing to accept the abovementioned course structure, in order to fit with a framework designed according to the student-centred Bologna approach, and the fundamental e-learning practices.
