Approaches and Strategies to Improve Writing Skills

I believe and, I hope others believe that writing well is not only a personal accomplishment but also a valuable form of social participation and leadership. After reviewing the literature, this work tries to identify the problem and to identify the key issues to EFL writing so as to suggest a remedial procedure that may help the learners to express themselves better in English. It aims at finding areas of difficulty in the writing skill among the students and to work out remedial procedures to help them overcome their weakness. A survey carried out on 12th grade students, regarding their comprehension, shows that organizing idea on paper is one of the factors which influences their ability to write. It also shows that students feel the need to be instructed on strategies of writing success and consequently improving their writing. There are a lot systematic approaches and methods for discerning which skills and type of writing teacher should focus on and meaningful classroom activities and strategies that teacher can use to help students improving their writing.

Socio-cultural determinants of adiposity and physical activity in preschool children: a cross-sectional study.

Both individual socio-cultural determinants such as selected parental characteristics (migrant background, low educational level and workload) as well as the regional environment are related to childhood overweight and physical activity (PA). The purpose of the study was to compare the impact of distinct socio-cultural determinants such as the regional environment and selected parental characteristics on adiposity, PA and motor skills in preschool children. Forty preschools (N = 542 children) of two culturally different urban regions (German and French speaking part of Switzerland) participated in the study (Ballabeina Study). Outcome measures included adiposity (BMI and skinfold thickness), objectively measured sedentary activities and PA (accelerometers) and agility performance (obstacle course). Parental characteristics (migrant status, educational level and workload) were assessed by questionnaire. Children from the French speaking areas had higher adiposity, lower levels of total and of more intense PA, were more sedentary and less agile than children from the German speaking regions (percent differences for all outcome parameters except for BMI ≥10%; all p ≤ 0.04). Differences in skinfold thickness, sedentary activities and agility, but not in PA, were also found between children of Swiss and migrant parents, though they were ≤8% (p ≤ 0.02). While paternal workload had no effect, maternal workload and parental education resulted in differences in some PA measures and/or agility performance (percent differences in both: ≤9%, p ≤ 0.008), but not in adiposity or sedentary activities (p = NS). Regional differences in skinfold thickness, PA, sedentary activities and agility performance persisted after adjustment for parental socio-cultural characteristics, parental BMI and, where applicable, children's skinfolds (all p ≤ 0.01). The regional environment, especially the broader social environment, plays a prominent role in determining adiposity, PA and motor skills of young children and should be implicated in the prevention of obesity and promotion of PA in children. clinicaltrials.gov NCT00674544.

Práticas de Apoio à Supervisão Pedagógica com Recurso a um Ambiente Virtual na Universidade de Cabo Verde

Neste artigo pretendemos relatar uma experiência de apoio à supervisão de estágio e de dinamização de duas disciplinas na licenciatura de Ciências da Educação – Percurso de Desenvolvimento Pessoal e Social na Universidade de Cabo Verde (Uni-CV), com recurso à Moodle. Esta experiência, em curso, enquadra-se num projeto de Investigação-Ação (IA) a decorrer e com o qual se pretende melhorar a prática de orientação/supervisão de estágios pedagógicos no contexto da Uni-CV. Este texto reporta-se a um dos momentos de desenvolvimento do projeto, relativo à caraterização das competências tecnológicas dos estagiários/estudantes, principais destinatários desta ação e das suas expectativas em relação ao trabalho com ambientes virtuais de aprendizagem. Os dados foram recolhidos com recurso a um inquérito por questionário e a partir da sua análise constatamos que os inquiridos têm alguma facilidade de navegação na Web, possuem também competências básicas para o trabalho em ambientes online, assim como vontade experienciar trabalhar em diferentes ambientes de aprendizagem. As principais dificuldades identificadas, prendem-se com a dificuldade de acesso a um computador e à Internet.

A constituição e o funcionamento de uma comunidade de prática de professores em educação para o desenvolvimento sustentável

Os conceitos de desenvolvimento sustentável e de educação para o desenvolvimento sustentável estão ainda em evolução o que torna pertinente, hoje, a tentativa de uma clarificação conceptual e sua posterior operacionalização. Além de promover a definição e uso correto dos termos, compete também ao ensino criar e desenvolver as competências necessárias para a sua operacionalidade. Esta investigação pretende contribuir para a autoformação de professores, nomeadamente de professores de Física e Química, em educação para o desenvolvimento sustentável. Pretende que os professores, e aqueles que beneficiam da sua ação, possam ser cidadãos críticos e responsáveis, numa sociedade local e simultaneamente global, que vive num tempo concreto mas, cada vez mais, consciente das repercussões futuras das suas ações e decisões. Tendo por base este objetivo criou-se uma comunidade de prática virtual constituída por professores de Física e Química de Portugal e de países africanos de língua oficial portuguesa. A formação em educação para o desenvolvimento sustentável constituiu o domínio da comunidade de prática. A água foi o tema motivador e aglutinador, pois sendo essencial à vida, torna-se no contexto educativo, e concretamente em educação para o desenvolvimento sustentável, num desafio ético, simultaneamente social, económico, ambiental e político. A prática reflexiva constituiu uma ferramenta fundamental da atividade da comunidade. Da análise da prática desta comunidade, que constituiu o objeto desta investigação, verificámos que os diferentes contextos geográficos, educacionais, culturais e de desenvolvimento dos professores proporcionaram uma participação diversificada na comunidade de prática. Esta participação permitiu, aos membros da referida comunidade, a criação e/ou o desenvolvimento das competências requeridas em educação para o desenvolvimento sustentável. Apesar da pertinência do tema confrontámo-nos com a falta de projetos de investigação semelhantes ao desta investigação, o que constituiu um maior desafio à sua realização.

TV or not TV? Subtitling and English skills

We study the influence of television translation techniques on the quality of the English spoken across the EU and OCDE. We identify a large positive effect for subtitled original version as opposed to dubbed television, which loosely corresponds to between four and twenty years of compulsory English education at school. We also show that the importance of subtitled television is robust to a wide array of specifications.We then find that subtitling and better English skills have an influence on high-tech exports, international student mobility, and other economic and social outcomes.

Between Equity and Differentiation: An Analytical Schema of the Social Function of Education

The educational sphere has an internal function relatively agreed by social scientists. Nonetheless, the contribution that educational systems provide to the society (i.e., their social function) does not have the same degree of consensus. Taking into consideration such theoretical precedent, the current article raises an analytical schema to grasp the social function of education considering a sociological perspective. Starting from the assumption that there is an intrinsic relationship between the internal and social functions of social systems, we suggest there are particular stratification determinants modifying the internal pedagogical function of education, which impact on its social function by creating simultaneous conditions of equity and differentiation. Throughout the paper this social function is considered a paradoxical mechanism. We highlight how this paradoxical dynamic is deployed in different structural levels of the educational sphere. Additionally, we discuss eventual consequences of this paradoxical social function for the inclusion possibilities that educational systems offer to individuals.

Returns to Foreign Language Skills in a Developing Country: The Case of Turkey

Foreign language skills represent a form of human capital that can be rewarded in the labor market. Drawing on data from the Adult Education Survey of 2007, this is the first study estimating returns to foreign language skills in Turkey. We contribute to the literature on the economic value of language knowledge, with a special focus on a country characterized by fast economic and social development. Although English is the most widely spoken foreign language in Turkey, we initially consider the economic value of different foreign languages among the employed males aged 25 to 65. We find positive and significant returns to proficiency in English and Russian, which increase with the level of competence. Knowledge of French and German also appears to be positively rewarded in the Turkish labor market, although their economic value seems mostly linked to an increased likelihood to hold specific occupations rather than increased earnings within occupations. Focusing on English, we also explore the heterogeneity in returns to different levels of proficiency by frequency of English use at work, birth-cohort, education, occupation and rural/urban location. The results are also robust to the endogenous specification of English language skills.

Cardiovascular risk factor profiles and their social gradient from adolescence to age 74 in a Swiss region.

BACKGROUND: Few European studies have investigated how cardiovascular risk factors (CRF) in adults relate to those observed in younger generations. OBJECTIVE: To explore this issue in a Swiss region using two population health surveys of 3636 adolescents ages 9-19 years and 3299 adults ages 25-74 years. METHODS: Age patterns of continuous CRF were estimated by robust locally weighted regression and those of high-risk groups were calculated using adult criteria with appropriate adjustment for children. RESULTS: Gender differences in height, weight, blood pressure, and HDL cholesterol observed in adults were found to emerge in adolescents. Overweight, affecting 10-12% of adolescents, was increasing steeply in young adults (three times among males and twice among females) in parallel with inactivity. Median age at smoking initiation was decreasing rapidly from 18 to 20 years in young adults to 15 in adolescents. A statistically significant social gradient in disfavor of the lower education level was observed for overweight in all age groups of women above 16 (odds ratios (ORs) 2.4 to 3.3, P < 0.01), for inactivity in adult males (ORs 1.6 to 2.0, P < 0.05), and for regular smoking in older adolescents (OR 1.9 for males, 2.7 for females, P < 0.005), but not for elevated blood pressure. CONCLUSION: Discontinuities in the cross-sectional age patterns of CRF indicated the emergence of a social gradient and the need for preventive actions against the early adoption of persistent unhealthy behaviors, to which low-educated girls and women are particularly exposed.

Educational expansion, intergenerational mobility and over-education

[eng] There is a vast literature on intergenerational mobility in sociology and economics. Similar interest has emerged for the phenomenon of over-education in both disciplines. There are no studies, however, linking these two research lines. We study the relationship between social mobility and over-education in a context of educational expansion. Our framework allows for the evaluation of several policies, including those affecting social segregation, early intervention programs and the power of unions. Results show the evolution of social mobility, over-education, income inequality and equality of opportunity under each scenario.

Age and gender differences in the social patterning of cardiovascular risk factors in Switzerland: the CoLaus study.

OBJECTIVES: We examined the social distribution of a comprehensive range of cardiovascular risk factors (CVRF) in a Swiss population and assessed whether socioeconomic differences varied by age and gender. METHODS: Participants were 2960 men and 3343 women aged 35-75 years from a population-based survey conducted in Lausanne, Switzerland (CoLaus study). Educational level was the indicator of socioeconomic status used in this study. Analyses were stratified by gender and age group (35-54 years; 55-75 years). RESULTS: There were large educational differences in the prevalence of CVRF such as current smoking (Δ = absolute difference in prevalence between highest and lowest educational group:15.1%/12.6% in men/women aged 35-54 years), physical inactivity (Δ = 25.3%/22.7% in men/women aged 35-54 years), overweight and obesity (Δ = 14.6%/14.8% in men/women aged 55-75 years for obesity), hypertension (Δ = 16.7%/11.4% in men/women aged 55-75 years), dyslipidemia (Δ = 2.8%/6.2% in men/women aged 35-54 years for high LDL-cholesterol) and diabetes (Δ = 6.0%/2.6% in men/women aged 55-75 years). Educational inequalities in the distribution of CVRF were larger in women than in men for alcohol consumption, obesity, hypertension and dyslipidemia (p<0.05). Relative educational inequalities in CVRF tended to be greater among the younger (35-54 years) than among the older age group (55-75 years), particularly for behavioral CVRF and abdominal obesity among men and for physiological CVRF among women (p<0.05). CONCLUSION: Large absolute differences in the prevalence of CVRF according to education categories were observed in this Swiss population. The socioeconomic gradient in CVRF tended to be larger in women and in younger persons.

Educational attainment and timing of fertility decisions

This paper focuses on timing of fertility decisions, conditional on the level of educational attainment of parents. Timing of fertility and educational attainment of parents rationalize the negative relationship observed in the data between hourly wages and childbearing. It is shown how the recent evolution in total fertility rates observed in developed countries could be in part the result of a transition from an early childbearing regime to a late childbearing regime. I develop a general equilibrium overlapping generations model in order to understand the joint determination of timing of childbearing decisions together with other household economic decisions in a life cycle framework. I show how idiosyncratic uncertainty might have asymmetric efects on completed fertility depending on timing of childbearing, generating the diferences in completed fertility observed between households that difer in their level of educational attainment.

Design of Optical Systems With Extended Depth of Field: an Educational Approach to Wavefront Coding Techniques

A practical activity designed to introduce wavefront coding techniques as a method to extend the depth of field in optical systems is presented. The activity is suitable for advanced undergraduate students since it combines different topics in optical engineering such as optical system design, aberration theory, Fourier optics, and digital image processing. This paper provides the theoretical background and technical information for performing the experiment. The proposed activity requires students able to develop a wide range of skills since they are expected to deal with optical components, including spatial light modulators, and develop scripts to perform some calculations.
