This paper intends to reflect on the search, in the process of teaching formation, of pre-defined contents for the teaching of Geography and History in the series of primary school. This desire for clarity about the appropriated contents for the various series often overshadows the real need to clarify what is the goal of teaching this or that content. It is necessary, in the teacher training, resume and historically contextualize this search for curriculum contents. The risk of prioritizing the discussion about contents is transforming the contents itself into the content goals of education. Reifying the contents contributes to the common process of disconnect teaching from learning. In this case, the educational process becomes a contest of teaching contents, not bothering if these contents were or not learned by the students, which makes education extremely conservative. This phenomenon has it origins in the 1970s, during the curriculum discussions of the various areas of school knowledge. Since then, the concept of didactic transposition has been questioned progressively, in which the curricula were designed as adapted teaching to lower levels of scientific knowledge produced in universities – the place for higher education. The school knowledge, since the 1970s, is considered as autonomous. In other words, knowledge in dialogue with university science, but with typical characteristics of education in school systems. If the curriculum of primary and secondary educations is not the result of the didactic transposition, what content it should be made of? The current paper touches this issue, but subordinates it to most relevant questions about the purposes of learning in inseparable connection with teaching.

The current research compared resting heart rate variability (VFC) before and after 10 weeks of strength training in groups that used and did not use a vibration platform. Seventeen healthy men were divided into conventional strength training (TF) or strength training using a vibration platform with a frequency of 30 Hz (TF+V30) training groups. One repetition maximum load (1-RM) on half squat exercise and VFC measurements were determined pre- and post-training program. Both groups had improved 1-RM load after the program (15.1% in TF group and 16.4% in TF+V30 group), although this increase was changed in the same extent for the two groups and there was no difference in 1-RM load between groups pre- and post-training program. No significant difference was observed in resting VFC measurements between groups pre and post-training program, however the magnitude of the effect size was moderated (ES = 0.50-0.80) for some variables (R-R interval, standard deviation of all R-R interval - SDNN, RMSSD, log-transformed of low frequency - InLF, and log-transformed of high frequency - InHF) in TF+V30 group. It was concluded that 10 weeks of strength training program with or without the vibration platform provided similar increase in 1-RM load in both groups, and although some evidences in this study indicate that vibration can increase vagal activity analyzed by ES, in neither groups the strength training was able to change VFC significantly.

Tobacco use is a major health hazard, and the onset of tobacco use occurs almost entirely in the teenage years. For this reason, schools are an ideal site for tobacco prevention programs. Although studies have shown that effective school-based tobacco prevention programs exist, all too frequently these programs are not used. In order for effective programs to achieve their potential impact, strategies for speeding the diffusion of these programs to school districts and seeing that, once adopted, programs are implemented as they are intended, must be developed and tested.^ This study (SC2) set out to replicate the findings of an earlier quasi-experimental study (The Smart Choices Diffusion Study, or SC1) in which strategies based on diffusion theory and social learning theory were found to be effective in encouraging adoption and implementation of an effective tobacco prevention program in schools. To increase awareness and encourage adoption, intervention strategies in both studies utilized opinion leaders, messages highlighting positive aspects of the program, and modeling of benefits and effective use through videotape and newsletters. To encourage accurate implementation of the curriculum, teacher training for the two studies utilized videotaped modeling and practice of activities by teachers. SC2 subjects were 38 school districts that make up one of Texas' 20 education service regions. These districts had served as the comparison group in SC1, and findings for the SC1 comparison and intervention groups were utilized as historic controls.^ SC2 achieved a 76.3% adoption rate and found that an average of 84% of the curriculum was taught with an 82% fidelity to methods utilized by the curriculum. These rates and rates for implementation of dissemination strategies were equal to or greater than corresponding rates for SC1. The proportion of teachers implementing the curriculum in SC2 was found to be equal to SC1's video-trained districts but lower than the SC1 workshop-trained group.^ SC2's findings corroborate and support the findings from the earlier study, and increase our confidence in its findings. Taken together, the findings from SC2 and SC1 point to the effectiveness of their theory-based intervention strategies in encouraging adoption and accurate implementation of the tobacco prevention curriculum. ^

O objetivo da presente tese é realizar uma abordagem acerca da realidade das entidades científicas no contexto da formação de professores de física. A literatura em ensino de ciências destaca a importância do entendimento de aspectos da natureza da ciência por professores. Dentre esses aspectos, exploramos a questão da realidade das entidades inobserváveis descritas pelas teorias científicas, tratando sobretudo de critérios utilizados para a caracterização dessa realidade por licenciandos, bem como possíveis influências na constituição desses critérios. Consideramos que um professor de física, durante sua atuação profissional, precisará lidar com a questão da realidade de entidades não acessíveis aos sentidos, tendo talvez de explicar em que se baseia uma proposição sobre sua existência. No desenvolvimento do presente trabalho, trouxemos alguns elementos de uma discussão que se dá no âmbito filosófico a respeito do realismo científico e também abordamos formulações teóricas que tratam da questão da realidade em perspectivas que se referem ao campo cotidiano e ao senso comum. Como referencial mais geral, utilizamos uma abordagem sobre cultura, que aponta para a influência de diversas estruturas culturais nas formas de entendimento do mundo e permite conceber a ciência como uma dessas estruturas. Entre outras coisas, a aprendizagem da ciência envolveria a compreensão de suas formas específicas de atribuir realidade, em contraposição às formas de outras estruturas culturais. Foram desenvolvidos três estudos, com análises fundamentadas em metodologias qualitativas. No primeiro, investigamos critérios usados por licenciandos em física para definir a realidade de entidades da ciência e de entes relacionados a outros domínios; no segundo, analisamos formas pelas quais certas entidades científicas são caracterizadas e tomadas como reais em uma coleção de livros didáticos de física do ensino superior; e, por fim, o terceiro consistiu na construção e utilização de um heurístico, com o objetivo de proporcionar reflexões acerca de questões relacionadas ao conhecimento científico e a elementos de outras estruturas culturais e foram analisadas as entrevistas de quatro estudantes de licenciatura sobre o uso desse instrumento. Os resultados obtidos parecem mostrar que há influência de elementos vindos de fora da ciência nos critérios utilizados por estudantes para a definição da realidade das entidades. Além disso, mostram que esse tema não é comumente trazido à reflexão dos alunos, o que não contribui para a reelaboração dos critérios de realidade já trazidos por eles de outros campos que não o científico. O heurístico utilizado no terceiro estudo serviu para trazer à tona as bases do pensamento dos estudantes e lhes indicar certos elementos para reflexão; existiram diferenças nos tipos de reflexão suscitados pelo instrumento, o que consideramos ser uma espécie de \"contextualização cultural\" na maneira de compreender as questões trazidas por ele. O desenvolvimento dos três estudos nos permitiu compreender alguns aspectos relevantes sobre os modos de entendimento das entidades da ciência e pensar sobre suas formas de tratamento em um curso de física.

Esta investigación presenta un estudio cuyo objetivo es identificar aspectos que apoyan el desarrollo de la mirada profesional en estudiantes para profesores de matemáticas en un contexto b-learning. Analizamos las producciones de un grupo de estudiantes para profesores de matemáticas de educación secundaria (documentos escritos y participaciones en un debate on-line) cuando analizaban el razonamiento proporcional de estudiantes de educación secundaria. Los resultados indican que la interacción en el debate en línea permitió a algunos estudiantes para profesor mejorar su capacidad de identificar e interpretar aspectos relevantes del pensamiento matemático de los estudiantes de educación secundaria. Estos resultados indican que el desarrollo de “una mirada profesional” del profesor es un proceso complicado pero que la posibilidad de construir un discurso progresivo en línea es un factor importante para su desarrollo.

El objetivo de esta investigación es caracterizar grados de desarrollo de la competencia docente “mirar con sentido” el pensamiento matemático de los estudiantes en el ámbito específico de la derivada de una función en un punto. A partir de los resultados de las investigaciones previas sobre la derivada diseñamos un cuestionario formado por tres tareas a partir de las respuestas de estudiantes a 3 problemas sobre el concepto de derivada en un punto. Los resultados han permitido generar descriptores de niveles de desarrollo de la competencia docente “mirar con sentido” el pensamiento matemático de los estudiantes. Estos resultados aportan información para el diseño de intervenciones en la formación de profesores de matemáticas que tengan como uno de sus objetivos el desarrollo de la competencia docente “mirar con sentido” el pensamiento matemático de los estudiantes.

El objetivo de esta investigación es indagar en el conocimiento especializado de contenido matemático de estudiantes para maestro (EPM) sobre problemas de división-medida. Los EPM respondieron a dos cuestionarios en los que resolvieron dos problemas de división-medida e interpretaron respuestas dadas por alumnos de primaria. Un alto porcentaje de EPM resolvieron con éxito los dos problemas, pero pocos fueron capaces de interpretar de forma adecuada las respuestas de los alumnos de primaria cuando empleaban un procedimiento correcto alternativo a la división. Los resultados obtenidos ofrecen a los formadores referencias iniciales acerca de los conocimientos de los EPM sobre problemas de división-medida y sobre el uso que hacen de estos conocimientos en una de sus tareas profesionales: interpretar las respuestas de los alumnos.

El objetivo de esta investigación es caracterizar perspectivas de estudiantes para profesores de educación secundaria (EPS) sobre el papel que puede desempeñar la tecnología para apoyar el aprendizaje matemático de los estudiantes. Los datos proceden de la planificación de una lección basada en la resolución de problemas mediante el uso de tecnología. Las perspectivas de los estudiantes para profesor se situaron a lo largo de un continuo considerando la relación entre: (i) lo que se pretendía con el uso de recursos tecnológicos y (ii) la naturaleza de la actividad matemática generada. La relación entre ambos aspectos ayuda a reconocer el papel que pueden desempeñar las perspectivas de los estudiantes para profesor cuando están aprendiendo a integrar la tecnología en la enseñanza de la resolución de problemas.

El objetivo de esta comunicación es caracterizar la mirada profesional de los estudiantes para maestro (EPM) cuando describen e interpretan respuestas de alumnos de Primaria a problemas de identificación de patrones. El estudio conjunto de los grados de evidencia de la identificación de los elementos matemáticos relevantes en el proceso de generalización de patrones y de la interpretación de la comprensión de los estudiantes, nos permitió identificar cinco perfiles de EPM con una gradación entre ellos. Esto nos ha llevado a caracterizar cinco perfiles de EPM que muestran que el conocimiento de matemáticas es necesario pero no suficiente para el desarrollo de una “mirada profesional”.

An on-line survey of experts was conducted to solicit their views on policy priorities in the area of information and communication technologies (ICT) in the Caribbean. The experts considered the goal to “promote teacher training in the use of ICTs in the classroom” to be the highest priority, followed by goals to “reduce the cost of broadband services” and “promote the use of ICT in emergency and disaster prevention, preparedness and response.” Goals in the areas of cybercrime, e-commerce, egovernment, universal service funds, consumer protection, and on-line privacy rounded out the top 10. Some of the lowest ranked goals were those related to coordinating the management of infrastructure changes. These included the switchover for digital terrestrial television (DTT) and digital FM radio, cloud computing for government ICT, the introduction of satellite-based internet services, and the installation of content distribution networks (CDNs). Initiatives aimed at using ICT to promote specific industries, or specific means of promoting the digital economy, tended toward the centre of the rankings. Thus, a general pattern emerged which elevated the importance of focusing on how ICT is integrated into the broader society, with economic issues a lower priority, and concerns about coordination on infrastructure issues lower still.

In order to examine the influence of sprint training on metabolism and exercise performance during sprint exercise, 16 recreationally-active, untrained, men (TO2peak= 3.8+/-0.1 1.min(-1)) were randomly assigned to either a training (n=8) or control group (n=8). Each subject performed a 30-sec cycle sprint and a test to measure VO2peak before and after eight weeks of sprint training. The training group completed a series of sprints three times per week which progressed from three 30-sec cycle sprints in weeks 1 and 2, to six 30-sec sprints in weeks 7 and 8. Three mins of passive recovery separated each sprint throughout the training period. Muscle samples were obtained at rest and immediately following the pre- and post-training sprints and analysed for high energy phosphagens, glycogen and lactate; the activities of both phosphofructokinase (PFK) and citrate synthase (CS) were also measured and muscle fibre types were quantified, Training resulted in a 7.1% increase in mean power output (p
