The role of digital stories and civic actions on student-teachers’ understanding about social sustainability in urban settings

Abstract

The present study aims to explore student-teachers’ (STs’) progress in understanding social urban sustainability and how it is affected through the development of digital stories and engagement in civic actions. Participants were 44 STs enrolled in a Department of Primary Education located in Northern Greece. Although participants were aware of the principles of sustainable development and education for sustainability, none of them had familiarity with social or urban sustainability. Three individual digital concept maps constructed before, intermediate and after the end of the course served as data sources. Both quantitative (significance testing, effect sizes, and confidence intervals) and qualitative (categories development) methods of analysis were implemented. Results indicate a sound improvement of STs’ understanding even in the intermediate concept maps with the most significant proposition gains associated with the society pillar. Moreover, despite the significant improvement in understanding of all main pillars of sustainability, this improvement was unbalanced because a minority of subcategories constituted the majority of STs’ propositions in all settings, indicating a strong and constructive combination between theory and praxis for the advancement of STs’ learning.     

A critical review of 13 years of mobile game-based learning

With the increasing popularity of smartphones and tablets, game-based learning (GBL) is undergoing a rapid shift to mobile platforms. This transformation is driven by mobility, wireless interfaces, and built-in sensors that these smart devices offer in order to enable blended and context-sensitive mobile learning (m-Learning) activities. Thus, m-Learning is becoming more independent and ubiquitous (u-Learning). In order to identify and analyze the main trends and the future challenging issues involved in designing mGBL learning strategies, as well as to bring to the foreground important issues pertaining to mobile and context-aware ubiquitous GBL, the work at hand conducts a comprehensive survey of this particular area. Specifically, it introduces and applies a six-dimensional framework consisted of Spatio-temporal, Collaboration/Social, Session, Personalization, Data security & privacy, and Pedagogy, with the aim of scrutinizing the contributions in the field of mGBL published from 2004 to 2016. It was found that the transition to mGBL presents several difficulties, and therefore cannot be conceived as a simple and quick modification of existing GBL solutions. In this respect, this work is anticipated to foster the development of well-designed solutions that are intensive not only in their technological aspect, but in pedagogical qualities as well.     

Adjusting athletes' body mass index to better reflect adiposity in epidemiological research

Abstract

The aim of the present study was to identify when body mass index (BMI) is unlikely to be a valid measure of adiposity in athletic populations and to propose a simple adjustment that will allow the BMI of athletes to reflect the adiposity normally associated with non-athletic populations. Using data from three previously published studies containing 236 athletes from seven sports and 293 age-matched controls, the association between adiposity (sum of 4 skinfold thicknesses, in millimetres) and BMI was explored using correlation, linear regression, and analysis of covariance (ANCOVA). As anticipated, there were strong positive correlations (r = 0.83 for both men and women) and slope parameters between adiposity and BMI in age-matched controls from Study 1 (all P < 0.001). The standard of sport participation reduced these associations. Of the correlations and linear-regression slope parameters between adiposity and BMI in the sports from Studies 2 and 3, although still positive in most groups, less than half of the correlations and slope parameters were statistically significant. When data from the three studies were combined, the ANCOVA identified that the BMI slope parameter of controls (5.81 mm · (kg · m^?2)^?1) was greater than the BMI slope parameter for sports (2.62 mm · (kg · m^?2)^?1) and middle-distance runners (0.94 mm · (kg · m^?2)^?1) (P < 0.001). Based on these contrasting associations, we calculated how the BMI of athletes can be adjusted to reflect the same adiposity associated with age-matched controls. This simple adjustment allows the BMI of athletes and non-athletes to be used with greater confidence when investigating the effect of BMI as a risk factor in epidemiological research.     

Exercising with Passion: Initial Validation of the Passion Scale in Exercise

Adequate response to mail health surveys by minority populations has proved problematic. The impact of mail survey design features utilized to promote Orthodox Jews' responses (N = 138; 82 eligible synagogue member households) to a mailed questionnaire used to measure walking behavior are described and assessed. An examination of response characteristics by wave as an estimate of nonresponse bias and calculations of response speed and cost-effectiveness were conducted. Response rates of 54.8% and 52.9% for eligible households and individuals, respectively, were accumulated by using 9 of 14 recommended mail survey techniques for this particular population (e.g., culturally appropriate salutation and closing, religious iconography, Talmudic aphorisms, and incentives linked to Hebraic numerology and the synagogue's building fund). Nonrespondents most frequently cited business, forgetfulness, or lack of topic salience as reasons for not responding. No differences on sociodemographic items and 9 of 11 continuous variables were observed by response wave; response speed was slowest in response to later mailing waves; and cost-effectiveness was maximal during postcard follow-up (E statistic = 3.74). Nonresponse bias may not be problematic with a > 50% response rate in this particular population. Front-loading incentives may prompt quicker response and improve cost-effectiveness. Specific design considerations for future consideration and testing are provided.     

Culture and the school: The degree of educational integration of Roma and Gypsies in the Peloponnese region of Greece

This article examines the degree of integration of Roma and Gypsy children in formal education in the Peloponnese region of Greece. It is based on field research conducted by the University of Patras during the school year 2006/07 within the framework of the Greek Ministry of Education’s “Integration of Roma children in school” programme, funded by the European Union. Despite governmental incentives for poor families to enrol their school-aged children, school attendance of Roma and Gypsy children was found to decline from primary year one to primary year six, with hardly any of them entering secondary school at all. Besides looking at school attendance figures and Roma and Gypsy children’s proficiency in reading, writing and numeracy, this paper also considers gender, family composition, living conditions and economic situation, as well as culturally constructed perceptions of childhood and a person’s life cycle. The aim of this article is to highlight the contradictions and ambiguities involved in the process of incorporating Roma and Gypsy children in formal education, and to evaluate their school performance and assess their academic choices.     

Students’ Reasoning about the Future of Disturbed or Protected Ecosystems & the Idea of the ‘Balance of Nature’

This paper is part of a larger study that aims at highlighting students’ interpretations of the idea of the ‘Balance of Nature’, as well as its use in their reasoning about the future of an ecosystem, in order to subsequently develop a learning environment that might promote a reconsideration of its validity and usefulness. Our focus here is particularly set on whether and how non biology-major students use this idea when making predictions about (a) the future of an ecosystem that is supposed to have suffered a human-driven disturbance, and (b) the future of an ecosystem that is supposed to be protected against such disturbances. Administering a questionnaire of 12 items - 4 of which concern us here - to 61 1st-year educational sciences students at the University of Patras, we traced - among others - their reasoning about (a) the future of three ecosystems (forest, sea, lake), supposed to have suffered different human-driven disturbances (fire, oil spill, new population introduction), and (b) the future of a protected forest ecosystem of a national park. According to our findings, most of the students found it very likely for a disturbed ecosystem to fully recover its initial state - mainly due to a ‘recovery process’ or inherent ‘recovery mechanisms’ - showing a strong belief in an extremely resilient ‘Balance of Nature’. Moreover, most of them appeared to believe that if human-protected, an ecosystem will be in a continuous ‘balance’, while very few were skeptical enough to claim a non-predictable future for it.     

Effective special teacher characteristics: perceptions of preschool special educators in Greece

The aim of the present study was to evaluate six characteristics of effective special pre‐school teachers, similar to those used in the relevant literature. The study participants were all special teachers (n = 226), serving in Greek state and community pre‐primary educational institutions (i.e. kindergartens and day nurseries) for children with learning disabilities. Data were collected through a two‐part questionnaire sent to the targeted special teachers (response rate 100%) and through focused group discussion with teachers. Three characteristics emerged as salient features of an effective teacher: love for the children; competent pre‐service training and ongoing professional development; and professionalism and commitment. The remaining three characteristics assessed (i.e. effective communication skills, a well‐rounded personality, and instructional ability) were also judged to be essential. Based on each characteristic’s analysis, the paper discusses the implications of pre‐service and in‐service training for special teachers.     

Achievement Goals and Persistence Across Tasks: The Roles of Failure and Success

The focus of this study is on the role of achievement goals in students’ persistence. The authors administered 5 puzzles to 96 college students: 4 unsolvable and 1 relatively easy (acting as a hope probe). They examined whether and how persistence may deteriorate as a function of failing the puzzles, as well as whether and how persistence may rebound after an event of success. Time spent engaging in the task comprised the dependent variable persistence (representing a behavioral aspect of engagement). Results suggested that mastery-oriented students persisted significantly longer compared with performance approach–oriented, performance avoidance–oriented, and amotivated students across failure trials. However, performance approach–oriented students were more likely to rebound after experiencing success. Qualitative data provided insights into the affective processes that accompanied engagement with the task.     

Relative age effect: implications for effective practice

Physical and psychological differences related to birthdate amongst athletes of the same selection year have been characterised as the “relative age effects” (RAEs). RAEs have been identified in a variety of sports, both at youth and adult level, and are linked with dropout of athletes and a reduction of the talent pool. This study examined the existence, mechanisms and possible solutions to RAEs using qualitative methodology. Seven experts in the field of talent identification and development were interviewed. Inductive analysis of the data showed that, while there was mixed evidence for the existence of RAEs across sports, the eradication of RAEs was attributed to controllable features of the development environment. The factors reported included the structure of “categories” used to group athletes within the sport (e.g. age, weight, size, skills), recognition and prioritisation of long-term development over “short term win focus.” Education of relevant parties (e.g. coaches, scouts, clubs) about RAEs and the nature of “talent” within a long-term context was suggested, along with careful consideration of the structure of the development environment (e.g. delayed selection, provision for late developers, focus on skills not results, use of challenge). Implications for research and practice are discussed.
