O ensino e a surpresa: experimentos surpreendentes e suas possibilidades no ensino de Física

Some experiments in Physics teaching have an amazing effect among the students, that is, generally be characterized by counteracting the initial expectations of students. This characteristic may contribute to the emergence of learning situations extremely promising. However, the privilege, by the teacher, the description of certain results shortens the involvement that the student could establish on teaching situations favor a more careful observation that can be done. We discuss in this paper, the that surprise may be manifested in the student on an experimental demonstration and its ability to mobilize the interest and curiosity of this student. We intend to observe the pedagogic value that represents the amazing effect such in situations of teaching and learning, particularly for the Teaching of Physics, as well as the possibilities for educational approaches.Through an extensive analysis of several authors who address about experimental learning activities, Epistemology of Science and Education, we found some results that lead us to understand some of the possibilities that the surprise element can propose. We describe a demonstration activity that we consider amazingly from our point of view and that was realized in a regular classroom in a of Rio Claro Public High School in the year of 2011

Elastic band causing exfoliation of the upper permanent central incisors

Objective. This study reports a case in which elastic band use culminated in the loss of the incisors. Case Report. An 11-year-old white girl was seen complaining of pain, with purulent discharge and severe tooth mobility. The bone destruction detected radiographically in the region, despite its single location and absence in posterior quadrants of the maxilla and/or mandible, was similar to that observed in Langerhans cell disease. To our surprise, an elastic band involving the midportion of the roots of the two upper central incisors was found during biopsy. The debris was removed and a metal wire was placed in permanent maxillary right and left incisors. The patient was followed up, but no improvement in tooth mobility was observed. Bone loss increased, and internal resorption and root exposure occurred, which culminated in the extraction of permanent maxillary right and left incisors. Conclusion. The present case highlights the fact that professionals sometimes are confronted by anamnestic reports never seen before.

O ensino de física e a curiosidade epistemológica: o uso de experimentos de eletricidade em atividades educacionais

We analyzed with this work the importance of using experiments in the classroom, especially the low-cost experiments for better learning of Physics, discussing the context where this discipline is inserted, which in general, has been presented to students in a traditional, mechanistic way. We worked with the electrostatic theme and low cost didactic experiments, focusing on the pizza electrophorus. About the handling of this experiment, we can see the surprise and curiosity in students, depending on how it is used in didactic activities in order to make it meaningful to the student. We discussed how the curiosity can be harnessed in the classroom, the types of curiosity according to Freire, how to overcome the curiosity to become epistemological, the physics involved in the experiment and the teacher's role in this context

Gramsci, o capital supranacional e o novo teorema da política

Gramsci é um autor da atualidade, teórico da mundialização do capitalismo, mas ainda desconhecido, mesmo no campo do marxismo, entre as suas tendências dominantes. Pensar a globalização, o século XXI, a nova conjuntura política nos quadros da contemporaneidade é um desafio intelectual da maior relevância que tem, em Gramsci – certamente para surpresa de uns e negação de outros –, uma de suas fontes mais estimulantes e reveladoras. É fascinante desvendar em seus escritos teses indispensáveis para refletirmos alguns dos principais temas do momento em horizontes mundiais.

Book Review of Twilight of the Mammoths: Ice Age Extinctions and the Rewilding of America by Paul S. Martin

Applying ecological studies to the adaptations of prehistoric human hunter-gatherer groups has greatly increased our abilities to interpret effects of an ever-changing environment and our access to critical resources on these populations. The Pleistocene/Holocene transition, its climate and human genesis in the new world, draws intensive interest from a number of scientific communities. In Twilight of the Mammoths, Paul Martin adds his views, which are of no surprise, on the megafaunal extirpations during a cultural period referred to in North America as Clovis.

Enhancing Problem Solving Through Math Clubs

This action research paper was about a mandatory math club of seventh graders that met once per week over a 12-week period. The students gathered in the classroom during their regularly scheduled math class. The focus of the math club was to solve challenging math problems, usually cooperatively, and sometimes competitively. The math club activities varied from week to week to offer an element of surprise. Frequently, the students presented their solutions to peers, along with an explanation of the way they solved the problem. Instruments were used to collect information about problem-solving accuracy, student attitudes, and student and teacher behaviors. I discovered a slight improvement in problem solving. Also, on Math Club days, the teaching was less teacher-centered and more student-centered. As a result of this research, I plan to offer my middle school students more problem-solving opportunities and I plan to allow my students to work cooperatively on a regular basis.

There’s a story that a construction foreman one day noticed one of his workers pushing his wheelbarrow upside down around the work site. “Hey,” the foreman shouted, “turn that thing right side up!” The man with the wheelbarrow looked at him in surprise. “Don’t be silly,” he said. “Every time I do that, they put bricks in it!” I think of that story sometimes, in the midst of these difficult economic times, as our states, its people, and its university, in turn, wrestle with budge cuts. Wouldn’t it be great if we all could just turn our wheelbarrows over and say, “No thanks, no more brick! No more heavy loads to haul!”

Being the mother of a pregnant adolescent: experiences and expectations

OBJECTIVE: To understand the typical actions of the mother during the pregnancy of her teenage daughter. METHODS: Qualitative study, based on the theoretical-methodological framework of social phenomenology of Alfred Schütz. The data were collected in 2009, and the subjects were nine mothers of adolescent primigravidae. RESULTS: The mother of the pregnant adolescent is typified as one that reacts with surprise and disappointment to being notified of the pregnancy and who, subsequently, conforms to the new reality. In reflecting on her own experience of an adolescent mother, she has expectations to support her daughter during the pregnancy and to offer support, so that the course of her life is not impaired as a result of pregnancy. CONCLUSION: Considering the experience and expectations of the mother of the pregnant adolescent, this study could give subsidies to the planning and execution of the care for this binomial, decreasing the distance between the demands made by it and the practice of health professionals.

Role of the amygdala in the reinforcement omission effect

The reinforcement omission effect (ROE) has been attributed to both motivational and attentional consequences of surprising reinforcement omission. Recent evidence suggests that the basolateral complex of the amygdala is involved in motivational components related to reinforcement value, whereas the central nucleus of the amygdala is involved in the processing of the attentional consequences of surprise. This study was designed to verify whether the mechanisms involved in the ROE depend on the integrity of either the basolateral amygdala complex or central nucleus of the amygdala. The ROE was evaluated in rats with lesions of either the central nucleus or basolateral complex of the amygdala and trained on a fixed-interval schedule procedure (Experiment 1) and fixed-interval with limited hold signaled schedule procedure (Experiment 2). The results of Experiment 1 showed that sham-operated rats and rats with lesions of either the central nucleus or basolateral area displayed the ROE. In contrast, in Experiment 2, subjects with lesions of the central nucleus or basolateral complex of the amygdala exhibited a smaller ROE compared with sham-operated subjects. Thus, the effects of selective lesions of amygdala subregions on the ROE in rats depended on the training procedure. Furthermore, the absence of differences between the lesioned groups in either experiment did not allow the dissociation of attentional or motivational components of the ROE with functions of specific areas of the amygdala. Thus, results did not show a functional double-dissociation between the central nucleus and basolateral area in the ROE.

Community-acquired pneumonia in Chile: the clinical relevance in the detection of viruses and atypical bacteria

Background Adult community-acquired pneumonia (CAP) is a relevant worldwide cause of morbidity and mortality, however the aetiology often remains uncertain and the therapy is empirical. We applied conventional and molecular diagnostics to identify viruses and atypical bacteria associated with CAP in Chile. Methods We used sputum and blood cultures, IgG/IgM serology and molecular diagnostic techniques (PCR, reverse transcriptase PCR) for detection of classical and atypical bacteria (Mycoplasma pneumoniae, Chlamydia pneumoniae, Legionella pneumoniae) and respiratory viruses (adenovirus, respiratory syncytial virus (RSV), human metapneumovirus, influenza virus, parainfluenzavirus, rhinovirus, coronavirus) in adults >18 years old presenting with CAP in Santiago from February 2005 to September 2007. Severity was qualified at admission by Fine's pneumonia severity index. Results Overall detection in 356 enrolled adults were 92 (26%) cases of a single bacterial pathogen, 80 (22%) cases of a single viral pathogen, 60 (17%) cases with mixed bacterial and viral infection and 124 (35%) cases with no identified pathogen. Streptococcus pneumoniae and RSV were the most common bacterial and viral pathogens identified. Infectious agent detection by PCR provided greater sensitivity than conventional techniques. To our surprise, no relationship was observed between clinical severity and sole or coinfections. Conclusions The use of molecular diagnostics expanded the detection of viruses and atypical bacteria in adults with CAP, as unique or coinfections. Clinical severity and outcome were independent of the aetiological agents detected.

La sorpresa come fattore critico indicatore di sintonizzazione emotiva in bambini normali e con disturbi pervasivi dello sviluppo

The topic of this study is surprise, re gard as an evolutionary complex process, with manifold implication in different fields, from neurological, since aspecific correlate of surprise exist more or less at every level of neuronal processes (e.g. Rao e Ballard, 1999.), to behavioral , inasmuch a s our ability to quickly valuate(assess), recognize and learn from surprising events, are be regarded as pivotal for survival (e.g. Ranganath e Rainer, 2003). In particular this work, going from belief that surprise is really a psychoevolutive mechanism of primary relevance, has the objective to investigate if there may be a substantial connection between development of surprise' emotion and specific developmental problems, or, if in subjects with pervasive developmental disorders surprise may embody (represent) a essential mechanism of emotional tuning, and consequently if abnormalities in such process may be at the base of at least a part of cognitive and behavioural problems that determine (describe) this pathology. Theoretical reasons lead us to conside r this particular pathologic condition, recall to a broad area of research concern the comprehension of belief as marker of ability to reasons about mental states of others (i.e. Theory of Mind), and in addition, at the detection of specific subjects' diff iculty in this field. On the experimental side, as well as limited of this work, we have to compare comprehension and expression of surprise in a sample of 21 children with pervasive developmental disorders (PDD), with a sample of 35 children without deve lopmental problems, in a range of age 3-12. Method After the customary approach to become friendly with the child, an experimenter and an accomplice showed three boxes of nuts, easily to distinguish one from the other because of their different colours an d , working together with the child, the contents of one of the boxes were replaced and a different material (macaroni, pebbles) was put in the box. for the purpose of preparing a surprise for someone. At this stage, the accomplice excused himself/herself and left and the experimenter suggested to the child that he prepare another surprise, replacing the contents in the second box. When the accomplice came back, the child was asked to prepare a surprise for him by picking out the box that he thought was the right one for the purpose. After, and the child doesn't know it, the accomplice change the content of one of the boxes with candies and asked out to the children to open the box, in order to see if he show surprise. Result Date have obtain a significant difference between autistic and normal group, in all four tests. The expression of surprise too, is present in significantly lower degree in autistic group than in control group. Moreover, autistic children do not provide appropriate metarappresentative explanations. Conclusion Our outcome, with knowledge of the limit of our investigation at an experimental level (low number of the champions, no possibility of video registration to firm the expressions ) orient to consider eventuality that surprise, may be seen as relevant component, or indicative, in autistic spectrum disorders.
