Teaching Multiplication with Lesson Study
Full text linkThis open access book is intended to assist teachers, teacher trainers, curriculum designers, editors and authors of textbooks in developing strategies to teach the multiplication of natural numbers based on the experience of the Lesson Study in Japan. This approach to mathematics education dates back to the 1870s and reconciles the emphasis on problem solving with the treatment of the curricular contents. It has gained international recognition since the 1990s and thanks to it mathematics education in Japan has been recognized as one of the most efficient and innovative in the world. This growing international awareness has led to an effort to apply the principles of Lesson Study to other parts of the world and this book shows how experienced authors from Brazil, Chile, Mexico, Spain and Portugal have worked to adapt some of these methods and techniques to the Portuguese and Spanish speaking countries of Ibero-America. Drawing on the impact of Lesson Study on government curriculum decisions and teacher behavior in Japanese classrooms; offering examples of lessons, lesson plans and suggestions for teaching; and presenting examples of the good reception of the principles of Lesson Study in Ibero-America, Teaching Multiplication with Lesson Study – Japanese and Ibero-American Theories for Mathematics Education shows how an efficient and cutting-edge experience in mathematics education can travel the world and help teachers in many different countries. ; Shows how teachers can apply the principles of Japanese Lesson Study to teach the multiplication of natural numbers Presents an approach to mathematics education that reconciles the emphasis on problem solving with the treatment of the curricular contents Provides examples of how a method developed in Japan can be adapted to different cultural contexts, such as the Portuguese and Spanish speaking countries of Ibero-Americ
Entendiendo la clase de matemática
Full text linkEste estudio parte del supuesto de que es recomendable alcanzar una comprensión del funcionamiento de la clase de matemática en condiciones no experimentales para orientar la innovación curricular en nuestro sistema escolar. Sobre la base del supuesto anterior se diseñó un estudio con el propósito de abstraer un modelo de la clase de matemática (Olfos, 1993), que provea elementos primarios para la elaboración futura de una teoría sobre la cual estructurar la enseñanza de matemática escolar en el nivel intermedio. Se adoptó un acercamiento cualitativo en el estudio de cuatro grupos cursos de octavo grado de primaria. Se utilizó la técnica de observación participante con un enfoque etnográfico en el trabajo de campo. Los análisis se realizaron de manera independiente en cada una de las cuatro aulas según los procedimientos de la teoría desde la base (Strauss & Corbin, 1990), construyendo así los modelos (descriptivos) de esas “clases de matemática”. Finalmente fue desarrollado un modelo global de la clase de matemática, el cual resultó tener su eje central en el “cómo la clase de matemática es llevada adelante por la subjetividad del maestro”
Matemática para la diversidad, equidad y sustentabilidad en infantil y primaria: un desafío para los países con alta segmentación social
Full text linkEn esta conferencia, se referirá al enfoque abierto para la enseñanza de la matemática, específicamente en el tema de los números y sus operaciones en preescolar y primaria. Se hablará sobre las Matemáticas para la diversidad, la equidad y la sustentabilidad en ámbitos escolares de primaria e infantil. Se aborda la temática como un desafío actual para los países que tienen alta segmentación social
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
La taxonomía de comprensión gráfica de Curcio a través del gráfico de Minard: una clase en septimo grado
Full text linkSe da a conocer una situación de aula basada en el gráfico de Minard cuyo objetivo es desarrollar en los alumnos la capacidad de comprensión gráfica, siguiendo la taxonomía de Curcio. La situación fue implementada en séptimo grado para facilitar la comprensión gráfica, como parte del desarrollo del pensamiento estadístico de los alumnos, una de las finalidades del área de Estadística y Probabilidades del currículo escolar. La propuesta estructurada bajo una visión constructivista del aprendizaje, provee a los estudiantes la oportunidad para elaborar estrategias personales usando sus conocimientos adquiridos y da oportunidad a los docentes para que orienten a sus estudiantes hacia la indagación y el desarrollo de un pensamiento autónomo, por sobre la adquisición de conocimientos específicos
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
