Estratégias de trabalho com blogs no ensino de geometria em turmas de 5° ano do ensino fundamental

This paper presents a survey conducted through collaborative work, which took place in a suburb school in the city of Uberlandia-MG. The research is characterized as case study and has a qualitative approach. Had the objective to look for different strategies of teaching and learning through the use of technology in pedagogical practice. Regarding the methodology in this research, we analyzed the work with the support of blogs, whose pages were used for student records and discussions directed to the geometry content. The students who were attending the fifth (5th) year of elementary school were invited to participate in this project. However, the research subjects were only those students who accepted the invitation to participate in the study through statement signed by parents. The project was developed with 30 students in the second half of 2014 and another 30 in the first half of 2015. The physical space at school, where most of the project activities were done was at the computer lab. In the process of compiling the data, at school, the following instruments were used: field notes produced by the entire project team, photographs and footage of the activities produced in the computer lab and in classroom (recorded by the research team) questionnaires, interviews, virtual space records: the blogs. The results of this research mainly focused on the analysis of the fifth year student‟s productions records in blogs. Regarding the conclusion, the research has shown that blogs, software and differentiated dynamic studies attracted the student‟s attention, leaving them mostly instigated by the unknown. Gradually, students built their own knowledge from their mistakes and successes. The entire work process enabled the computer lab to be an environment that is used not just to solving computerized and tedious drills. The blogs production work in groups, developed in students the reading and writing of both the mother language as symbols and mathematical nomenclature. The interaction between students became noticeable throughout the project, since it provided the student‟s personal growth, respect, tolerance and mutual cooperation. In this sense, we concluded that the project greatly contributed to the students' literacy process in the mother language, mathematics and computer literacy.

An investigation into the tension arising between natural language and mathematical language experienced by mechanical engineering students

This investigation is grounded within the concept of embodied cognition where the mind is considered to be part of a biological system. A first year undergraduate Mechanical Engineering cohort of students was tasked with explaining the behaviour of three balls of different masses being rolled down a ramp. The explanations given by the students highlighted the cognitive conflict between the everyday interpretation of the word energy and its mathematical use. The results showed that even after many years of schooling, students found it challenging to interpret the mathematics they had learned and relied upon pseudo-scientific notions to account for the behaviour of the balls.

Matematik Öğretmeni Adaylarının Dörtgenleri Sınıflandırma Becerilerinin İncelenmesi

This study aimed to explore prospective teachers’ performance on recognizing quadrilaterals with their special cases and constructing a hierarchical classification of them. The participants consisted of 44 freshmen studying at a public university’s elementary school mathematics education department. Data was collected with a question form containing two questions at the first day of the geometry course taught in the second term of the first year. For quantifying the data of the first question, while students who identify the prototypes of quadrilaterals and their special cases were given 1 and 2 points for each correct answer respectively, -1 point was given for each incorrect answer. The similarity index was employed to quantify students’ concept maps. We investigated that students could detect the prototypes of the quadrilaterals but not their special cases. Additionally, the similarity index between majority of freshmen’ concept maps and the referent map was found as low or moderate.

Number comparison and number ordering as predictors of arithmetic performance in adults: Exploring the link between the two skills, and investigating the question of domain-specificity.

Recent evidence has highlighted the important role that number ordering skills play in arithmetic abilities (e.g., Lyons & Beilock, 2011). In fact, Lyons et al. (2014) demonstrated that although at the start of formal mathematics education number comparison skills are the best predictors of arithmetic performance, from around the age of 10, number ordering skills become the strongest numerical predictors of arithmetic abilities. In the current study we demonstrated that number comparison and ordering skills were both significantly related to arithmetic performance in adults, and the effect size was greater in the case of ordering skills. Additionally, we found that the effect of number comparison skills on arithmetic performance was partially mediated by number ordering skills. Moreover, performance on comparison and ordering tasks involving the months of the year was also strongly correlated with arithmetic skills, and participants displayed similar (canonical or reverse) distance effects on the comparison and ordering tasks involving months as when the tasks included numbers. This suggests that the processes responsible for the link between comparison and ordering skills and arithmetic performance are not specific to the domain of numbers. Finally, a factor analysis indicated that performance on comparison and ordering tasks loaded on a factor which included performance on a number line task and self-reported spatial thinking styles. These results substantially extend previous research on the role of order processing abilities in mental arithmetic.

Konkret material i matematikundervisningen – bekymmer och motsättningar : En systematisk litteraturstudie om laborativ matematik

Laborativt arbete med konkret material är en arbetsform inom matematiken som på en del håll åter fått uppsving i ett försök att råda bot på svenska elevers försämrade prestationer i och intresse för matematik. Denna litteraturstudies syfte är att undersöka vilka faktorer som kan påverka negativt vid laborativt arbete med konkret material i matematikundervisningen. I resultatet av litteraturstudien synliggörs huvudsakligen två faktorer som är av större betydelse för undervisningens utfall samt en faktor av mindre betydelse, elevernas ålder. Den första faktorn behandlar valet av material och materialets utformning, vilket kan inverka på elevernas förståelse. Om det konkreta materialet är mycket likt de föremål elever möter i sin vardag, såsom pizzaslices eller pengar, kan denna likhet störa elevernas matematiska förståelse genom att för stor uppmärksamhet riktas mot igenkännandet och att se föremålen som potentiella leksaker, istället för att se dem som konkreta symboler för abstrakt matematik. Detta tycks inte åldersbetingat, utan förekommer i olika årskurser. Den andra faktorn som uppmärksammats är lärarens vägledande roll. Läraren behöver adekvat kompetensutveckling och professionellt stöd i arbetet med konkret material för att öka chanserna att arbetssättet får ett så gynnsamt utfall som möjligt. Läraren spelar en stor roll i både valet av konkret material och i hur instruktioner samt vägledning ges. Det är också viktigt att läraren i undervisningen bjuder in till interaktion och kommunikation om elevernas funna resultat och lösningsförslag för att stärka elevernas förståelse. Sökandet efter relevant litteratur genomfördes i AABRI, ERIC, Google Scholar, Libris, och Summon.

Problem solving competency and the mathematical kangaroo

The goal of the study was to investigate differences in how two groups of students activated mathematical competencies in the mathematical kangaroo (MK). The two groups, group 1 and 2, were identified from a sample of 264 students (grade 7, age 13) through high achievement (top 20 %) in only one of the tests: the MK or a curriculum bounded test (CT). Analysis of mathematical competencies showed that the high achievers in the MK, activated the problem solving competency to a greater extent than the high achievers in the CT, when doing the MK. The results indicate the importance of using non-traditional tests in the assessment process of students to be able to find students that might possess good mathematical competencies although they do not show it on curriculum bounded tests.

This paper includes some fundamental ideas about the theory of didactic transposition of Yve Chevallard (1980), from which it is made an analysis of the knowledge transformation suffers from the mathematical level to the scholastic level. To demonstrate this transformation, it is analyzed the theme of integers, which is included in the seventh- grade curriculum of the educational system of Costa Rica.

Diseño de un modelo de situación problema, con la unidad facilitadora solidaria llamada Belisol, para fortalecer el pensamiento numérico y variacional, en los estudiantes de la Institución Educativa Rural Benigno Mena González

Al analizar los resultados deficientes de las Pruebas Saber, del PTA ( Programa Todos a Aprender del MEN), y la participación en las Olimpiadas del Conocimiento, de los estudiantes de la Institución Educativa Rural Benigno Mena González del municipio de San Jerónimo, se consideró implementar un proyecto pedagógico, como plan de mejoramiento para la enseñanza y aprendizaje de las matemáticas, que sirviera como una iniciativa para fortalecer los pensamientos numérico y variacional en los estudiantes de secundaria de la Institución; se buscaba, con la implementación de esta propuesta, desarrollar habilidades en dominio, comprensión y solución de situaciones problemas cotidianas dentro del contexto escolar y desde la innovación de nuevas prácticas metodológicas en los procesos educativos. Desde esta perspectiva, nace el interrogante: ¿Cómo modelar una situación problema, teniendo como motivo la unidad facilitadora solidaria denominada Belisol, para fortalecer el pensamiento numérico y variacional, en los estudiantes de la Institución Educativa Rural Benigno Mena González del municipio de San Jerónimo?, para dar tránsito a una propuesta de investigación innovadora. Ahora bien, para intervenir y reflexionar sobre este interrogante, se propuso el método de Investigación Acción Participación (IAP), el cual se aplica a estudios que se interesan sobre realidades humanas y problemáticas cotidianas o sociales, que además, sean reales, de la acción, y de constante participación de los sujetos, entidades o comunidades involucradas; aquí cabe la posibilidad de un aprendizaje cooperativo, colectivo, y por supuesto, colaborativo donde se ha planteado como motivo de la situación problema planteada la unidad financiera llamada Belisol con el fin de exteriorizar los fundamentos de una acción formativa, orientada a la incursión en el ámbito de la educación matemática económica financiera, a través del ejercicio del ahorro escolar y el trueque, promoviendo de esta manera el espíritu solidario en la comunidad Benigniana.

Sentimento de pertença psicológica : uma contribuição da educação na educação social inclusiva na cidade de Arapiraca no Estado de Alagoas Brasil

ABSTRACT Background: The school needs proficiar education able to meet the needs of every child regardless of the social and physical condition linguistically. Objective: This study aims to identify the sense of psychological belonging as a contribution to inclusive social education in the city of Arapiraca / al. Method: The methodology used to conduct this study was triangulated. The quantitative, descriptive and explorative, it was .desenvolvido at a school in Arapiraca - AL, in the period from January 2014 to March 2014, having been asked 38 students and their teachers with special necessidaes. With regard to the qualitative study was chosen for conducting interviews with teachers and students. Results: We questioned 38 students with special educational needs and 20 teachers, and it was found that 25% of teachers have specific training and 75% have no specific training. As for the students most had needs intellectual level. As for the teachers felt unprepared to meet students with special educational needs. On the other hand, it is important to note that among the students surveyed most are affected by stress and depression and reported that such things happen because you often see in the classroom in situations that do not know how to solve and when they seek help, found. Conclusion: The school, set in this context has an important role follow the changes, preparing their students more consciously to exercise citizenship by providing means proficionais skilled resources to this function. It is within the perspectiva of inclusive education we believe to achieve in the future, a society where everyone has their rights respected. The sense of psychological belonging experienced by educators in the classroom has special students is part of their lives. School social inclusion is a process that involves access, retention and success of students, but that requires a lot of educator and many times that is not prepared to answer all the expectations of the particular student. Focusing on the issue of the current situation that the public school experience, is undoubtedly recognize the need for changes in their practices. The search we are undertaking it is to carry on with this discussion in order to build the mission of educators grounded in a conscious inclusion within the educational possibilities available today. Key - words: Education. Inclusion. Citizenship. Psychological, Feeling of belonging.
