Criterios para el análisis, selección, secuenciación y organización de los contenidos educativos en el currículo: aplicación a la secuenciación de contenidos de biología en la educación primaria

L'objectiu bàsic d'aquesta investigació es elaborar una proposta de criteris útil per a l'elaboració i revisió de les seqüències de continguts educatius al currículum. Per dur-lo a terme, s'han desenvolupat les tasques següents: - Revisió critica de les diferents aportacions al tema des de la psicologia, l'epis¬temologia i la didàctica. - Elaboració d'un conjunt de criteris, fonamentals i relacionats, per orientar el professorat i els dissenyadors de currículums i materials curriculars en la presa de decisions sobre la manera de presentar i desenvolupar els continguts educatius en els plans d'ensenyament, englobant de manera simultània les dife¬rents variables que intervenen. - Estudi d'un cas en el qual un equip docent d'Educació Primària elabora una seqüència educativa per a l'estudi dels essers vius, i l'experimenta a l'aula, ba¬sant-se en la proposta de criteris realitzada. L'estudi del cas ha cobert un període de quatre anys de treball conjunt de l'investigador i l'equip docent. Hipòtesis de treball: L'establiment d'un conjunt de criteris explícits que orientin l'anàlisi i l'elaboració de seqüències de continguts educatius per part dels equips docents pot ajudar a millorar el disseny i el desenvolupament del currículum als centres. Se suposa que els criteris esmentats: 1. Proporcionaran als docents una millor comprensió dels continguts educatius que ensenyen, de la seva estructura lògica i psicològica i, en conseqüència dels as¬pectes més rellevants per a l'ensenyament. 2. Situaran el professorat en unes millors condicions per elaborar seqüències d'ensenyament fonamentades i progressives. 3. Facilitaran l'adaptació de Is continguts educatius a les capacitats, el conei¬xements i les experiències prèvies de l'alumnat. 4. Afavoriran una presentació dels continguts a l'alumnat més organitzada i relacionada. 5. Comentaran un tractament mes equilibrat i integrat dels diferents tipus de continguts. Conclusions: - Els criteris proposats s'han mostrat útils i coherents per ajudar a analitzar i reconduir les seqüències educatives, mitjançant hipòtesis explícites fonamentades que els donin més coherència. - El tipus d'intervenció realitzada i la metodologia utilitzada en l'estudi del cas, basades a l'observació participant s'han mostrat útils per tractar els pro¬blemes plantejats. - Els resultats del treball realitzat tenen repercussions en la formació inicial i permanent del professorat i en el disseny dels currículums i materials curri¬culars. D'una altra banda, la seva generalització faria necessari la seva rèplica en altres etapes i àrees curriculars.

Metabolic profiles and progesterone cycles in first lactation dairy cows

This study investigated the ovarian function, metabolic profiles and fertility in first lactation Holstein-Friesian dairy cows (mean 305 day milk yield: 7417 +/- 191 kg, n = 37). Reproductive profiles obtained from milk progesterone analysis were categorized into normal (n = 17) and four abnormal profiles (delayed ovulation, DOV1, n = 9; DOV2, n = 2; persistent corpus luteum, PCL1, n = 6; PCL2, n = 4; 1: immediately post-calving, 2: subsequent cycles). Fifty-five percent of cows had abnormal profiles with half of these being categorized as DOV1. Fertility of DOV1 and DOV2 cows was reduced whereas PCL1 and PCL2 cows had similar reproductive competence to normal profile cows. DOV1 animals had higher milk energy values, lower energy balances, lower dry matter intakes (DMI) and greater body weight and body condition score (BCS) losses post-calving than normal profile animals. DOV1 animals also had lower insulin-like growth factor-I (IGF-I) and higher betahydroxybutyrate (BHB) concentrations and tended to have the lower insulin and glucose concentrations in the pre-service period than normal profile cows. All PCL animals had vulval discharges postpartum. Despite this, the DMI, body weight and BCS changes, IGF-I concentrations and fertility of PCL1 animals was similar to normal profile cows. In conclusion, the high prevalence of delayed ovulation post-calving (DOV1) in primiparous high yielding cows lasted long enough (71 +/- 8.3 days) to have a detrimental impact on fertility and was associated with significant physiological changes. This study did not establish any detrimental effects of PCL profiles on fertility or production parameters. (C) 2002 Elsevier Science Inc. All rights reserved.

The status of literature: English teaching and the condition of literature teaching in schools

Although the curriculum subject of English is continually reviewed and revised in all English speaking countries, the status of literature is rarely questioned i.e. that it is of high cultural value and all students should be taught about it. The concerns of any review, in any country, are typically about what counts as literature, especially in terms of national heritage and then how much of the curriculum should it occupy. This article reports on three inter-related pieces of research that examine the views of in-service, and pre-service, English teachers about their experiences of teaching literature and their perceptions of its ‘status’ and significance at official level and in the actual classroom; it draws attention to how England compares to some other English speaking countries and draws attention to the need to learn from the negative outcomes of political policy in England. The findings suggest that the nature of engagement with literature for teachers and their students has been distorted by official rhetorics and assessment regimes and that English teachers are deeply concerned to reverse this pattern.

Inclusive approaches to teaching and learning mathematics

This chapter explores the role of mentors in supporting pre-service teachers to include all children in mathematics teaching, no matter what their individual needs.

Om lärarskapets moraliska dimension : ett perspektiv och en studie av lärarstuderandes nätbaserade seminariesamtal

In this dissertation, an educational perspective called the moral dimension of teaching is developed. The work includes a theoretically informed discussion from a pragmatist point of view in which the concept of pedagogical rhythm is introduced. The concept captures the need for teachers to regularly shift their intentions and occasionally act in contradictory ways as a consequence of the moral which emerges from interaction in pedagogical situations. Using this perspective, criteria are developed for the characteristics of discussions of the work of teachers, which are desirable in order for students in pre-service teacher education to have opportunities to develop their teachership. Secondly, the educational perspective as it is conceptualised serves as a theoretical framework for a study of discussions taking place in net-based seminars among students in teacher education. The study consists of 14 recorded seminars in which discussions of the work of teachers are analysed in terms of content and direction for reflection. The result of the analysis is a construction of four different focal points for processes of making judgements: existential, performative, critical and professional. Mainly the performative, and to some extent the critical, focal points appear to be supported by the net-based environment, although potential for the professional focal point is found when available tools in net-based settings are used in deliberate ways. Finally, based on these four focal points, possible future predispositions among student teachers are deliberated. Student teachers’ future opportunities to develop a moral and epistemological authority are discussed, as well as teachers’ general opportunities to exercise professional responsibility. The conclusion emphasises that a perspective such as the one developed in the dissertation is important, as it creates an understanding for the need to educate student teachers to exercise a form of responsibility that goes beyond being accountable to society.

Narrativas de professores em formação sobre a didatização de podcasts para o ensino de inglês na floresta

Considering the following conditions: (1) the fluency demands of students in an undergraduate program in Languages and Literatures/English in the Amazon region; (2) the listening and speaking needs of pre-service teachers of English as a Foreign Language (EFL); (3) my continuing education as a professor of EFL and my academic literacy as a teacher-researcher and pre-service-teacher trainer, this study, which is based on Narrative Inquiry, reports on a teacher experience of working didactically with oral genres through podcasting an activity that emerged with the advent of Information and Communication Technology (ICT). Through this process, I engage with some theorists who promote teaching as a process that is driven by a concept of language as social practice. Subsequently, I make use of the notions of context of culture and context of situation, derived from Systemic Functional Linguistics, as well as the concept of genre and register derived from the perspective of this theory. Based on these principles and beliefs, the Amazon region constitutes the register (situation) of the genres used in this study. These principles also provide, opportunities for building learning strategies appropriate to this local context, and also to teach listening and speaking skills from a task-based approach. During the experience, based on the reflective teacher-education model, the participants produced narratives about the process, which I then analyzed according to Ely, Vinz, Downing and Anzul (2001), who propose possibilities of composing meanings in Narrative Inquiry. Based on this perspective, I discuss the following topics, which were highly emphasized in the participants narratives: the lack of didactic activities using oral genres; the relevance of context within teacher education; and collaborative work as a strategy to overcome gaps in digital literacy, language fluency and teaching skills. The meanings I thereby compose point to a paradigm shift in English language teaching within this context. I also argue for a pedagogical practice that is engaged with historical and socio-cultural issues, and with the development of language skills, also one that promotes the implementation of ICTs at the very start of teacher training programs, adopting teaching and learning strategies that correspond to the demands of fluency in this particular context, and deficiencies imposed by geographical isolation

Formação inicial de professores de Biologia: a metodologia colaborativa mediada pelo computador e a aprendizagem para a docência

Este artigo apresenta os resultados da implantação e aplicação da metodologia colaborativa mediada pelo computador desenvolvida com alunos de Prática de Ensino de Biologia da UEM. Apoiando-se na abordagem qualitativa, os dados foram coletados em questionários, documentos e observações, e a análise sobre as ideias, concepções e reflexões dos sujeitos da pesquisa processou-se de acordo com três grupos de elementos formativos para docência construindo a identidade profissional, construção do conhecimento compartilhado e mediação. Concluiu-se que os Alunos-Professores (AP) passaram por significativas mudanças atitudinais com relação ao processo de ensino-aprendizagem e ao papel do professor, na medida em que, ao compreenderem a importância de se valorizar o uso da metodologia colaborativa e do computador, como recurso pedagógico no ensino-aprendizagem de Biologia, contemplando-os na experiência vivida, construíram saberes para a docência.

Reflexão e identidade profissional do professor de LE: que histórias contam os futuros professores?

Este artigo relata os resultados de um estudo realizado com alunas de graduação em Letras, Português - Língua Estrangeira (Inglês, Espanhol, Italiano, Japonês, Francês e Alemão). Objetivou verificar as metáforas, regras da prática e princípios que as alunas identificaram durante um processo de reflexão sobre suas formações profissionais. Foi possível identificar o impacto desses elementos em seus processos individuais de desenvolvimento de identidades como professoras. O resultado foi um conjunto de histórias biográficas escritas (fontes de experiências) nas quais as participantes se baseavam para constituir suas identidades profissionais como professoras de línguas estrangeiras. Nesses processos, elas puderam construir ligações significativas entre os aspectos teóricos evidenciados nas leituras que realizaram durante o período da pesquisa e os vários eventos marcantes de suas narrativas orais acerca da carreira profissional. A associação dos vários aspectos de suas histórias pessoais às questões teóricas que foram discutidas durante a pesquisa revela processos de construções de identidades profissionais como professoras de línguas estrangeiras.
