Educação matemática através de interfaces computacionais: o papel de componentes interativos na postura exploratória e na aprendizagem

Neste trabalho, investigamos o papel de componentes interativos, frequentemente utilizados na construção de interfaces computacionais educativas, na postura exploratória do estudante e na aprendizagem de conceitos matemáticos. Selecionamos para esta pesquisa os seguintes componentes: caixa de combinações (combo box) e campo de texto (text field). Do ponto de vista educacional, estes componentes têm papéis distintos: o primeiro orienta as escolhas do estudante durante um processo exploratório, enquanto que o segundo não oferece qualquer orientação. Para comparar o papel desses componentes, desenvolvemos duas interfaces computacionais interativas através das quais o estudante pode explorar o comportamento gráfico de uma função do primeiro grau. Ambas as interfaces são idênticas entre si, a menos do componente interativo empregado: em uma delas foi utilizado a caixa de combinações e em outra o campo de texto. Tanto a postura exploratória quanto o desempenho em testes de conhecimento foram avaliados a partir de medidas diretas registradas pelas próprias interfaces. A postura exploratória foi avaliada através do número e do tipo de interações do estudante com o componente interativo, sendo este registro uma das características singulares desta pesquisa, pois permite a observação de alguns comportamentos do estudante durante o processo de interação com a interface, e não somente antes e após a interação. Dentro da limitação da ferramenta de coleta de dados da presente pesquisa, a aprendizagem foi medida através da comparação do desempenho em testes de conhecimento aplicados antes e depois do uso dos componentes interativos pelos estudantes. Neste contexto, diferenças significativas no papel de cada componente na postura exploratória e na aprendizagem foram então observadas.

The interactive whiteboard in primary school: a case study of a brazilian district school

Interactive whiteboards (IWB) consist of a set of technological equipment organized in order to fulfill a specific task, enabling the development of didactic activities. Because they are associated to computers’ potentiality, interactive whiteboards can provide bigger interactivity between: teacher and students, students and content, and among students. This work’s main objective is to present some of the results yielded from a research related to the way students perceive interactive whiteboards in the classroom. In order to analyze the IWB usage dynamics, some educational applications in the field of mathematics were applied in the 3rd grade of elementary school. Aside from observation, video recordings were made and students were interviewed about the interactive whiteboard, in order to understand how these students observe and engage with the technological tool. IWB do not transform classroom’s reality by themselves, however, their physical presence and usage amount to external reinforcement can change student’s behavior positively.

Calculators in a Middle School Mathematics Classroom: Helpful or Harmful?

In this action research study of my classroom of eighth grade mathematics, I investigated the use of calculators. Specifically, I wanted to know the answer to three questions. I wanted to know more about what would happen to my students’ ability to recall basic math facts, their ability to communicate mathematically during problem solving, and their attitude when my students were or were not permitted to use their calculator. I discovered that in my research, I did not find enough evidence to either support or reject my initial hypotheses, that calculators largely influenced my students’ behavior, and also that my students’ ability to recall basic math facts would change when using a calculator. As a result of this research, I plan to continue my research within my classroom. I plan to further investigate the use of calculators within my classroom.

Relação entre violência física, consumo de álcool e outras drogas e bullying entre adolescentes escolares brasileiros

O objetivo deste estudo foi identificar a associação entre o consumo de álcool e outras drogas e o bullying com o envolvimento em situações de violência física entre adolescentes de 13 a 15 anos, em escolas públicas e privadas das capitais brasileiras e do Distrito Federal. Foram analisados os dados da Pesquisa Nacional de Saúde do Escolar (PeNSE) de 2009. Para análise dos dados foi utilizada a regressão logística. A prevalência de envolvimento em situações de violência física foi 12,9% maior no sexo masculino. Em ambos os sexos, foram observadas associações entre violência física e ser vítima de bullying com o uso de drogas ilícitas e efeito potencializado do consumo de álcool e drogas. Para o sexo masculino, o uso de álcool mostrou associação significante com violência física. Morar o pai ou ambos os genitores na residência apresentou associação inversa para violência física no sexo feminino. O conhecimento de fatores associados à violência física entre adolescentes é importante para auxiliar estratégias de promoção da saúde e da cultura de paz, rompendo com a ideia de que a violência entre adolescentes é algo banal e esperado.

Evaluating Bucknell's Waste Stream

This thesis examines three questions regarding the content of Bucknell University‟s waste stream and the contributors to campus recycling and solid waste disposal. The first asks, “What does Bucknell‟s waste stream consist of?” To answer this question, I designed a campus-wide waste audit procedure that sampled one dumpster from each of the eleven „activity‟ types on campus in order to better understand Bucknell‟s waste composition. The audit was implemented during the Fall semester of the 2011-2012 school year. The waste from each dumpster was sorted into several recyclable and non-recyclable categories and then weighed individually. Results showed the Bison and Carpenter Shop dumpsters to contain the highest percentage of divertible materials (through recycling and/or composting). When extrapolated, results also showed the Dining Services buildings and Facilities buildings to be the most waste dense in terms of pounds of waste generated per square foot. The Bison also generated the most overall waste by weight. The average composition of all dumpsters revealed that organic waste composed 24% of all waste, 23% was non-recyclable paper, and 20% was non-recyclable plastic. It will be important to move forward using these results to help create effective waste programs that target the appropriate areas of concern. My second question asks, “What influences waste behavior to contribute to this „picture‟ of the waste stream?” To answer this question, I created a survey that was sent out to randomly selected sub-group of the university‟s three constituencies: students, faculty, and staff. The survey sought responses regarding each constituency‟s solid waste disposal and recycling behavior, attitudes toward recycling, and motivating factors for solid waste disposal behaviors across different sectors of the university. Using regression analysis, I found three statistically significant motivating factors that influence solid waste disposal behavior: knowledge and awareness, moral value, and social norms. I further examined how a person‟s characteristics associate to these motivating factors and found that one‟s position on campus proved a significant association. Consistently, faculty and staff were strongly influenced by the aforementioned motivating factors, while students‟ behavior was less influenced by them. This suggests that new waste programs should target students to help increase the influence of these motivators to improve the recycling rate and lower overall solid waste disposal on campus. After making overall conclusions regarding the waste audit and survey, I ask my third question, which inquires, “What actions can Bucknell take to increase recycling rates and decrease solid waste generation?” Bucknell currently features several recycling and waste minimization programs on campus. However, using results from the waste audit and campus survey, we can better understand what are the issues of the waste stream, how do we go about addressing these issues, and who needs to be addressed. I propose several suggestions for projects that future students may take on for summer or thesis research. Suggestions include targeting the appropriate categories of waste that occur most frequently in the waste stream, as well as the building types that have the highest waste density and potential recovery rates. Additionally, certain groups on campus should be targeted more directly than others, namely the student body, which demonstrates the lowest influence by motivators of recycling and waste behavior. Several variables were identified as significant motivators of waste and recycling behavior, and could be used as program tactics to encourage more effective behavior.

Reto educativo : la incorporación de la perspectiva de género en los libros de texto : contrastes y semejanzas entre los manuales empleados en Castelo Branco, Portugal y Michoacán, México

El objetivo de este artículo es presentar los resultados del análisis de un conjunto de libros de texto con la finalidad de averiguar si las imágenes en ellos contenidas promueven los principios de igualdad y equidad de género. La muestra tomada para el estudio se compone de un total de seis manuales del curso escolar 2010/2011, tres de Michoacán, México, y tres de Castelo Branco, Portugal, correspondientes a las asignaturas de ciencias, lengua y geografía. Se utilizaron estratégias metodológicas mixtas, debido a que el empleo de métodos de corte cuantitativo y de corte cualitativo nos ofrece la posibilidad de elaborar un análisis que, además de contrastar los datos obtenidos, profundiza sobre la temática abordada. Los resultados obtenidos indican que los y las adolescentes no disponen, en los manuales examinados, de referentes suficientes que les permitan romper/ deconstruir los estereotipos de género tradicionalmente atribuidos a uno y otro sexo. Tanto las ilustraciones como el contenido de las mismas muestran mayoritariamente a mujeres desempeñando papeles psicosociales relacionados con el cuidado de los otros/as, mientras que los hombres aparecen casi siempre realizando trabajos remunerados y de prestigio (científicos, gobernantes). En las conclusiones de este artículo se cuestiona la presencia del sexismo en los libros de texto, con la intención de incorporar la perspectiva de género a los manuales didácticos, lo que permitiría transmitir al alumnado patrones de comportamiento y modelos que se ajusten a una realidad social regida por la igualdad y la justicia.

Young women as smokers and nonsmokers: A qualitative social identity approach

The authors used a social identity perspective to explore young women's perceptions of smoking. They carried out 13 focus groups and 6 intercept interviews with women aged 16 to 28 years in regards to the social identities that might influence young women's smoking behavior. Three identities emerged: the cool smoker applied to the initiation of smoking; considerate smokers, who were older addicted smokers; and the actual and anticipated good mother identity, which applied to young women who quit smoking during pregnancy. These identities add to our understanding of the meaning of smoking within the lives of young women and might allow more focused initiatives with this group to prevent the progression to regular addicted smoking.
