This paper addresses beginning teachers thinking about the nature and purposes of their subject and the impact of this on their practice. Individual qualitative interviews were undertaken with 11 history teachers at the beginning of their teaching careers. Data was analysed using writing as the method of analysis and revealed that teachers whose thinking was at odds with dominant discourses, for example in the form of a national curriculum, encountered difficulties embracing pedagogies and aspects of the curriculum that do not accord with their own deep-seated beliefs, demonstrating a need for the initial training and professional development of teachers to forefront consideration of subject understandings.

This paper focuses on young children’s scientific preconceptions and discusses teachers’ identification of these preconceptions when teaching science in the early years, on which research is still limited. This paper is based on the theoretical framework of constructivism and it defines preconceptions as children’s erroneous concepts prior to formal education. A two phase case study approach was employed, facilitating in-depth investigation though the use of questionnaires, interviews and observations. The results indicate that the teachers did not dedicate time to identify children’s preconceptions when planning and teaching science, even when acknowledging preconceptions’ possible existence. This indicates a possible lack of appreciation of the importance of children’s preconceptions of the consequences when ignoring them. The results also indicate the need for further training and professional development in relation to the teaching of early-years science, especially since only a very small percentage of early years teachers tend to study science during their years compulsory education. A number of suggestions are also provided for practice and policy that can be useful for other subjects as well.

Aimed at reducing deficiencies in representing the Madden-Julian oscillation (MJO) in general circulation models (GCMs), a global model evaluation project on vertical structure and physical processes of the MJO was coordinated. In this paper, results from the climate simulation component of this project are reported. It is shown that the MJO remains a great challenge in these latest generation GCMs. The systematic eastward propagation of the MJO is only well simulated in about one-fourth of the total participating models. The observed vertical westward tilt with altitude of the MJO is well simulated in good MJO models, but not in the poor ones. Damped Kelvin wave responses to the east of convection in the lower troposphere could be responsible for the missing MJO preconditioning process in these poor MJO models. Several process-oriented diagnostics were conducted to discriminate key processes for realistic MJO simulations. While large-scale rainfall partition and low-level mean zonal winds over the Indo-Pacific in a model are not found to be closely associated with its MJO skill, two metrics, including the low-level relative humidity difference between high and low rain events and seasonal mean gross moist stability, exhibit statistically significant correlations with the MJO performance. It is further indicated that increased cloud-radiative feedback tends to be associated with reduced amplitude of intraseasonal variability, which is incompatible with the radiative instability theory previously proposed for the MJO. Results in this study confirm that inclusion of air-sea interaction can lead to significant improvement in simulating the MJO.

It has been suggested that Assessment for Learning (AfL) plays a significant role in enhancing teaching and learning in mainstream educational contexts. However, little empirical evidence can support these claims. As AfL has been shown to be enacted predominantly through interactions in primary classes, there is a need to understand if it is appropriate, whether it can be efficiently used in teaching English to Young Learners (TEYL) and how it can facilitate learning in such a context. This emerging research focus gains currency especially in the light of SLA research, which suggests the important role of interactions in foreign language learning. This mixed-method, descriptive and exploratory study aims to investigate how teachers of learners aged 7-11 understand AfL; how they implement it; and the impact that such implementation could have on interactions which occur during lessons. The data were collected through lesson observations, scrutiny of school documents, semi-structured interviews and a focus group interview with teachers. The findings indicate that fitness for purpose guides the implementation of AfL in TEYL classrooms. Significantly, the study has revealed differences in the implementation of AfL between classes of 7-9 and 10-11 year olds within each of the three purposes (setting objectives and expectations; monitoring performance; and checking achievement) identified through the data. Another important finding of this study is the empirical evidence suggesting that the use of AfL could facilitate creating conditions conducive to learning in TEYL classes during collaborative and expert/novice interactions. The findings suggest that teachers’ understanding of AfL is largely aligned with the theoretical frameworks (Black & Wiliam, 2009; Swaffield, 2011) already available. However, they also demonstrate that there are TEYL specific characteristics. This research has important pedagogical implications and indicates a number of areas for further research.

School reform is a major concern in many countries that seek to improve their educational systems and enhance their performances. In consequence, many global schemes, theories, studies, attempts, and programmes have been introduced to promote education in recent years. Saudi Arabia is one of these countries that implemented educational change by introducing many initiatives. The Tatweer Programme is one of these initiatives and is considered as a major recent reform. The main purpose of this study is to investigate this reform in depth by examining the perceptions and experiences of the Tatweer leaders and teachers to find out which extent they have been enabled to be innovative, and to examine the types of leadership and decision-making that have been undertaken by such schools. This study adopted a qualitative case study that employed interviews, focus groups and documentary analysis. The design of the study has been divided into two phases; the first phase was the feasibility study and the second phase was the main study. The research sample of the feasibility study was head teachers, educational experts and Tatweer Unit’s members. The sample of the main study was three Tatweer schools, Tatweer Unit members and one official of Tatweer Project in Riyadh. The findings of this study identified the level of autonomy in managing the school; the Tatweer schools’ system is semi-autonomous when it comes to the internal management, but it lacks autonomy when it comes to staff appointment, student assessment, and curriculum development. In addition, the managerial work has been distributed through teams and members; the Excellence Team plays a critical role in school effectiveness leading an efficient change. Moreover, Professional Learning Communities have been used to enhance the work within Tatweer schools. Finally the findings show that there have been major shifts in the Tatweer schools’ system; the shifting from centralisation to semi-decentralisation; from the culture of the individual to the culture of community; from the traditional school to one focused on self-evaluation and planning; from management to leadership; and from an isolated school being open to society. These shifts have impacted positively on the attitudes of students, parents and staff.

We present a minor but essential modification to the CODEX 1D-MAS exchange experiment. The new CONTRA method, which requires minor changes of the original sequence only, has advantages over the previously introduced S-CODEX, since it is less sensitive to artefacts caused by finite pulse lengths. The performance of this variant, including the finite pulse effect, was confirmed by SIMPSON calculations and demonstrated on a number of dynamic systems. (C) 2007 Elsevier Inc. All rights reserved.

The aim of this article is to describe how the Learning Study method (LS) was implemented in a Swedish upper secondary school, as well as how the principals and the teachers involved perceived this to affect teaching at, and the development of, the school. It is an empirical study that was conducted as an action research project over a period of three years. The project to implement the LS method was based on the assumption that proper training is the result of collegial activity that occurs when teachers learn from each other. The teachers in this study were, in general, positive about using the LS method. It created opportunities to meet and talk about teaching skills, developed better professional relationships between colleagues, and offered a systematic method for planning, implementing and monitoring teaching. However, working together requires that time be set aside to allow for implementation of the LS method. This is crucial, as the LS method is a rather expensive way to make school development work. This places heavy demands on principals to create the necessary conditions for the implementation of the LS method.

Vocational teachers in Swedish upper secondary schools are a heterogeneous category of teachers, connected to different types of trade. These teachers represent a broad set of trade skills varying in content and character. In their teacher role, they continue to wear the clothes, speak the language, share the culture and remain mentally in their former professions. Still, it is central that they keep up this contact to be able to school the pupils into the environment of the trade in question, but also to help them to understand what skills a profession demands. However, the individual teacher also has to distance himself from the negative elements in the culture of the profession: patterns and habits that, for various reasons, have to be broken or changed. This paper draws attention to the ways in which a group of vocational teachers, who were participants in a project that aimed to train unauthorized vocational teachers, expressed their ambitions to prepare the pupils for a future professional career. When collecting information, we used the degree dissertations they produced and discussed in seminars, and informal dialogues. The result shows that it is important that the instruction location resembles a real working site as far as possible. These places are more or less realistic copies of a garage, a restaurant kitchen, a hairdressing salon, and so on, in order to give the pupils a realistic setting for instruction. However, the fact that these simulated workplaces lack the necessary support functions that exist in a company creates problems, problems which make a lot of extra work for the teachers. Vocational teachers also have to instruct the pupil in the experienced practitioner’s professional skills and working situation, but the pupil herself/himself must learn the job by doing it in practice. Some vocational upper secondary programs lack relevant course literature and the businesses give little support. This also makes extra work for the teachers. Moreover, the distance between the vocational programs and the trainee jobs was experienced as being difficult to overcome. One reason seems to be differences between businesses and differing preconditions between small and big companies’ abilities to take care of these pupils. The upper secondary school vocational programs also play a role in cementing existing gender roles, as well as perpetuating class-related patterns on the labour market.

O objetivo do presente trabalho tem duplo sentido,em primeiro lugar sugerir um tipo de universidade dirigido ma1S para a pratí ca profissional, selecionando, orientando e formando o estudante atraves de um acompanhamento pela Psicologia Aplicada, assim corno contri - buir com os estudantes de nível médio e superior, através de uma visão do funcionamento do ensino regido por outras universidades de alguns paises do mundo. E bastante exíguo o numero de publicações sobre universidades, principalmente no Brasil, o que coloca os estudiosos do assunto em dificuldades no conhecimento de outros métodos de ensino assim como a sua forma ou técnica de funcionamento. Obras existentes, sobre o assunto, em sua ma10r1a, se limitam a publicações apenas das atividades internas das universidades, ma1S no sentido administrativo e de sua direção, assim como divulga çoes estatísticas de número de formando, sem menC10nar contudo o fluxo grama de sua estrutura psico-pedagógica. O trabalho é rigorosamente fundamentado nas pesqu1sas, ob servações e conclusões advindas de vários anos de experiência no magi~ terio, nao so na area do ensino médio, inclusive industrial, como no ensino superior. Aborda inicialmente uma V1sao concisa da evolução da un1- vers idade, comp lemen tada por uma exp lanação detalhada do ens ino em var1as universidades de outros países, inclusive com seus pré-requisitos. Outra abordagem fundamental, e feita tambem, no sentido ' dos relacionamentos da universidade com o ensino técnico profissional' de nível medio, abordando paralelamente a importância do mercado de trabalho e da Pesquisa Tecnológica. são abordados aspectos da formação de professores e da atualização e especialização para a terceira idade frente a sua experiencia profissional. Finalmente é apresentado um novo tipo de Universidade,que acreditamos ser de alta relevância para o País, tal a gama de areas de ensino que ira atingir, conduzindo os estudantes do maternal ã terceira idade, dentro de uma seleção técnica justa, uma orientação profis - sional autêntica e dentro de seus dotes, assim como uma formação rea lista dentro da ciência, das letras e das artes para cada estudante. Uma comparação do ensino na Universidade Técnica propostacom o enS1no seguido pelas outras universidades, do mundo, facilita uma visão mais clara para que o trabalho nao possa ser considerado como um resumo arbitrário ou "utópico", ou que possa deformar a realidade do ensino complexo, até hoje existente.

O presente estudo teve como objetivo investigar a atitude do professor face à sua profissão. Pretendeu-se determinar, nesta atitude, a influência dos fatores tempo de atuação no magistério, tipo de formação universitária e pertinência à rede de ensino oficial ou particular. Uma vez que não há uma definição de atitude que cubra todos os tipos de determinação atitudinal, na presente investigação, considerou-se que a atitude envolve um estado de satisfação ou insatisfação em relação aos seguintes objetos atitudinais considerados como pertinentes à profissão de professor: desempenho no trabalho, motivação para o trabalho, status social da profissão, status econômico da profissão, formação técnica, atualização profissional, apoio à profissão, coesão na classe e contribuição para a educação. A amostra foi retirada da população de professores da Rede Estadual e Particular de Ensino do Município de Cabo Frio, no Estado do Rio de Janeiro. Para a pesquisa, elaborou-se uma escala de atitude em duas fases distintas: a escala de atitude - forma experimental e a escala de atitude -forma definitiva. Os resultados encontrados permitem concluir que o fator tempo de atuação no magistério provoca uma diferença significativa quanto ao estado de satisfação do professor, pois o escore médio obtido na escala pelos professores com 5 anos ou mais de atuação foi significativamente superior ao escore médio obtido pelos professores com menos de 5 anos de atuação no magistério. Os outros fatores, tipo de formação universitária e pertinência à rede de ensino particular ou oficial, não se mostraram significativos para o estabelecimento de diferenças significativas quanto ao estado de satisfação do professor.

In this paper we test whether the disclosure of test scores has direct impacts on student performance, school composition and school inputs. We take advantage of the discontinuity on the disclosure rules of The National Secondary Education Examination (ENEM) run in Brazil by the Ministry of Education: In 2006 it was established that the 2005 mean score results would be disclosed for schools with ten or more students who took the exam in the previous year. We use a regression discontinuity design to estimate the e ects of test disclosure. Our results indicate that private schools that had their average scores released in 2005 outperformed those that did not by 0.2-0.6 in 2007. We did not nd same results for public schools. Moreover, we did not nd evidence that treated schools adjusted their inputs or that there was major changes in the students composition of treated schools. These ndings allow us to interpret that the main mechanism driving the di erences in performance was the increased levels of students', teachers' and principals' e ort exerted by those in schools that had scores publicized.

Companies are moving to a more international structure; going into new markets and having an increased competition in all fronts. Therefore, the practices that lead companies to a more efficient and competitive position are praised. The management of the workforce comes as one of the main concerns of companies, aiming at performance enhancing and at creating better environments that both attract and maintain the professional talents. In an increasingly international environment, companies tend to look for the specialists and best professionals, regardless of their nationality. This new structure with several different nationalities working together poses new challenges for companies. Understanding if and how a more diverse has a relationship with financial performance is the starting point for better managing this new corporate structure.

This paper discusses who the legal directors are in private companies in Brazil, emphasizing their profile, career, and performance, focusing on the period of 2008- 2013, investigating changes which have occurred to legal departments in those companies, and to legal directors’ careers. Our argument is that since the expansion of legal departments in Brazil in the 1990s, with expanding privatizing of companies and further opening of the Brazilian market to foreign capital, the profiles and careers of legal directors have undergone several transformations, culminating in more value and prestige being given to those professionals inside companies. This paper explores these transformations and the a series of implications generated for the corporate legal market in the country, ranging from changing the criteria for hiring professionals, to creating new demands for more sophisticated legal services.
