POR UM ENSINO APRENDENTE: A FORMAÇÃO DE PROFESSORES DAS CIÊNCIAS NO SÉCULO XXI

A presente pesquisa investiga a formação de professores das ciências e sua perspectiva para o século XXI, a partir da análise das manifestações acadêmico-científicas de docentes doutores pesquisadores em educação científica nas áreas de Biologia, Química, Física, Matemática e Ciências da Natureza. Trata-se de uma pesquisa de natureza qualitativa, cuja narrativa procura contemplar aspectos de formação dessas áreas em meio aos conflitos, embates, especificidades e necessidades do atual contexto educacional. Busco tratar de visões e assumir posições sobre o que os professores das Ciências precisam aprender, pela configuração das tendências de formação e das práticas de ensino e de aprendizagem consideradas no século XX, bem como das projeções do que se põe como desejável para o século XXI. Nesse âmbito, identifico cinco categorias analíticas que são postas a partir de entrevistas junto aos meus sujeitos de pesquisa. Em relação à primeira categoria de pesquisa as tendências apontam que os conteúdos científicos são imprescindíveis, porém não suficientes durante o processo educativo, havendo necessidade de juntar o seu valor formativo. A segunda categoria traz a consideração do aluno no processo de aprender e ensinar ciências. Dentre o que não pode mais ser admissível neste século, a terceira categoria discute a dissociação entre ciência, tecnologia e sociedade atrelada a uma visão fragmentada de ciência. A quarta categoria aponta o que é posto de novidade na formação de professores das ciências, e a quinta categoria põe em discussão as necessidades formativas de professores das ciências para o século XXI. As análises dessas tendências em função dos relatos e entrevistas desses sujeitos de pesquisa são responsáveis pela integração entre o ensinar e o aprender, compartilhando os saberes pedagógicos, filosóficos, sociológicos, científicos. A partir da literatura atual sobre a formação de professores de ciências, procuro dar conta de algumas inquietações que permeiam a investigação e corroboram com uma mudança epistemológica do ensino: Quais aspectos devem ser prioritariamente considerados no âmbito da formação de professores das ciências? Quais as necessidades formativas desses professores? As contribuições acadêmicas a respeito dos saberes profissionais dos professores têm contribuído sobremaneira para o estabelecimento de uma cultura reflexiva em torno da prática docente de forma bastante crítica. Palavras-chave: 1. Formação de professores; 2. Ensino das ciências; 3. Necessidades formativas no século XXI.

School mathematics and dyslexia: aspects of the interrelationship

This investigation sought to explore the nature and extent of school mathematical difficulties among the dyslexic population. Anecdotal reports have suggested that many dyslexics may have difficulties in arithmetic, but few systematic studies have previously been undertaken. The literature pertaining to dyslexia and school mathematics respectively is reviewed. Clues are sought in studies of dyscalculia. These seem inadequate in accounting for dyslexics' reported mathematical difficulties. Similarities between aspects of language and mathematics are examined for underlying commonalities that may partially account for concomitant problems in mathematics, in individuals with a written language dysfunction. The performance of children taught using different mathematics work-schemes is assessed to ascertain if these are associated with differential levels of achievement that may be reflected in the dyslexic population few are found. Findings from studies designed to assess the relationship between written language failure and achievement in mathematics are reported. Study 1 reveals large correlational differences between subtest scores (Wechsler Intelligence Scale for Children, Wechsler, 1976) and three mathematics tests, for young dyslexics and children without literacy difficulties. However, few differences are found between levels of attainment, at this age (6 ½ - 9 years). Further studies indicate that, for dyslexics, achievement in school mathematics, may be independent of measured intelligence, as is the case with their literacy skills. Studies 3 and 4 reveal that dyslexics' performances on a range of school mathematical topics gets relatively worse compared with that of Controls (age range 8 - 17 years), as they get older. Extensive item analyses reveal many errors relating strongly to known deficits in the dyslexics' learning style - poor short-term memory, sequencing skills and verbal labelling strategies. Subgroups of dyslexics are identified on the basis of mathematical performance. Tentative explanations, involving alternative neuropsychological approaches, are offered for the measured differences in attainment between these groups.

How habits, social ties, and economic switching barriers affect customer loyalty in contractual service settings

While existing literature acknowledges positive effects of satisfaction and economic switching barriers for building customer loyalty, studies analyzing interactions of these antecedents reveal mixed findings. Prior research does not consider, as antecedents of switching barriers, either habits or social ties that result from shared service-usage within a family or community. This paper contributes to the literature, first, by replicating the effects of satisfaction, economic switching barriers, and their interaction with customer loyalty and word-of-mouth of subscribers to a contractual service. Second, the study empirically tests the role of social ties as a social switching barrier. Third, the study introduces and tests the effects of habits as a precursor of economic and social switching barriers. Results reveal significant positive effects of satisfaction, economic switching barriers, and social ties on customer loyalty and word-of-mouth. Additionally, economic switching barriers and social ties interact significantly with satisfaction and habits act as a precursor of economic switching barriers and social ties.

Networks of learning : how motorsport companies collaborate and share knowledge:evidence from the UK and Italian motorsport industries

The motorsport industry is a high value-added and highly innovative business sector. The UK’s leading racing car manufacturers are world class centres of research, development and engineering. However, individual firms in the sector do not have the range and depth of capabilities to compete independently in motorsport’s dynamic and competitive environment. Industry attention has therefore progressively focused on how networks of collaborating firms can work together to develop new products, improve business processes and reduce costs. This report presents findings from a three year Cardiff Business School study which examined the ways in which firms collaborate as part of wider networks. The research involved gathering data from over 120 firms in the UK and Italian motorsport sectors.

How brand attribute typicality and consumer commitment moderate the influence of comparative advertising

This study examines how product attribute typicality and brand commitment influence the effects of comparative versus non-comparative ads on brand attitudes. Employing perspectives from the literatures on typicality and commitment, the study examines the effects of commitment to the comparison brand on the effectiveness of comparative versus non-comparative advertising. A between-informants experiment uses data from 466 student informants. It is hypothesized that (a) when the attribute under consideration is typical (atypical), among comparison brand committed informants, a non-comparative ad is more (no more) persuasive than a comparative ad, (b) when the attribute under consideration is typical, among comparison brand non-committed informants, a comparative ad is more persuasive than a non-comparative ad, and (c) when the attribute under consideration is atypical, among comparison brand non-committed informants, a comparative ad is likely to be more persuasive than a non-comparative ad, but the effect will be weaker than in the case of a typical attribute. Hypothesis (a) is supported while (b) has directional support. The results support a three-way interaction between consumer commitment, attribute typicality, and type of advertisement. The findings are relevant to a variety of contexts, such as markets characterized by high levels of market share and commitment for the market leader as well as fragmented markets where market share and commitment levels are low.

How are task reflexivity and intercultural sensitivity related to the academic performance of MBA students?

Higher education in business school environments is increasingly focused on how to best equip students with the skills necessary for leadership in the global workplace. This paper examines the impact of two particularly important cognitive capabilities - task reflexivity and intercultural sensitivity, on academic performance in an MBA programme. It was hypothesised that in an intercultural learning environment, task reflexivity would be associated with higher academic performance, and that this relationship would be mediated via intercultural sensitivity. Questionnaire data from 77 MBA students was analysed alongside academic performance. Results demonstrated that task reflexivity was indirectly related to academic performance through intercultural sensitivity. These findings suggest that engagement in task reflexivity enables students to develop greater levels of intercultural sensitivity, allowing them to reap the positive effects of diversity in their peer group for their own learning and performance. Limitations and practical implications of the research for professional practice are discussed. © 2014 © 2014 Society for Research into Higher Education.

How doctors' communication style and race concordance influence African-Caribbean patients when disclosing depression

Objective: To determine the impact of doctors' communication style and doctor-patient race concordance on UK African-Caribbeans' comfort in disclosing depression. Methods: 160 African-Caribbean and 160 white British subjects, stratified by gender and history of depression, participated in simulated depression consultations with video-recorded doctors. Doctors were stratified by black or white race, gender and a high (HPC) or low patient-centred (LPC) communication style, giving a full 2. ×. 2. ×. 2 factorial design. Afterwards, participants rated aspects of doctors' communication style, their comfort in disclosing depression and treatment preferences. Results: Race concordance had no impact on African-Caribbeans' comfort in disclosing depression. However a HPC versus LPC communication style made them significantly more positive about their interactions with doctors (p = 0.000), their overall comfort (p = 0.003), their comfort in disclosing their emotional state (p = 0.001), and about considering talking therapy (p = 0.01); but less positive about considering antidepressant medication (p =0.01). Conclusion: Doctors' communication style was shown to be more important than patient race or race concordance in influencing African Caribbeans' depression consultation experiences. Changing doctors' communication style may help reduce disparities in depression care. Practice Implications: Practitioners should cultivate a HPC style to make African-Caribbeans more comfortable when disclosing depression, so that it is less likely to be missed.

Exploring how social workers experience and cope with public perception of their profession

The public’s perception of the social work profession is a rarely considered perspective, and yet a topic that is a concern to front Thepublic’sperceptionofthesocialworkprofessionisararelyconsideredperspective and yet a topic that is a concern to front line professionals. This paper explores how social workers experience and attempt to cope with public perception of their profession. It highlights the impact of these concerns on social workers’ personal experiences and professional practice. Using semi-structured interviews with sixteen UK social workers, from local authorities and private organisations,we explore the experiences of this group.Thematic analysis of the data identified four concerns: the experience of public perception, drivers of public perception, coping with public perception, and mechanisms to raise the professions profile. Examining public perception through the eyes of social workers provides valuable insights into the lived experiences of these professionals, and offers practical implications at both the micro and macro levels. It reveals two key ways in which the profession can begin to address the prevailing negative perception considered to be emanating from the public: through developing a more co-operative relationship with external sources of public perception (e.g. government and the media) and by engaging in more pro-active self-promotion of the service.

Jury decision making and the Story Model: How do deliberation style and evidence order influence the story that juries create?

This study investigated the utility of the Story Model for decision making at the jury level by examining the influence of evidence order and deliberation style on story consistency and guilt. Participants were shown a video-taped trial stimulus and then provided case perceptions including a guilt judgment and a narrative about what occurred during the incident. Participants then deliberated for approximately thirty minutes using either an evidence-driven or verdict-driven deliberation style before again providing case perceptions, including a guilt determination, a narrative about what happened during the incident, and an evidence recognition test. Multi-level regression analyses revealed that evidence order, deliberation style and sample interacted to influence both story consistency measures and guilt. Among students, participants in the verdict-driven deliberation condition formed more consistent pro-prosecution stories when the prosecution presented their case in story-order, while participants in the evidence-driven deliberation condition formed more consistent pro-prosecution stories when the defense's case was presented in story-order. Findings were the opposite among community members, with participants in the verdict-driven deliberation condition forming more consistent pro-prosecution stories when the defense's case was presented in story-order, and participants in the evidence-driven deliberation condition forming more consistent pro-prosecution stories when the prosecution's case was presented in story-order. Additionally several story consistency measures influenced guilt decisions. Thus there is some support for the hypothesis that story consistency mediates the influence of evidence order and deliberation style on guilt decisions.
