Integración de Manipulativos Virtuales para la Enseñanza y el aprendizaje del Perímetro y el Área en la Educación Básica Secundaria
Full text linkIntroduction. The integration of digital resources in mathematics education has shown promise in improving students’ conceptual understanding. Virtual manipulatives, in particular, are designed to support abstract reasoning through interactive and visual learning environments. Objective. This study aimed to evaluate the impact of virtual manipulatives on seventh-grade students’ learning outcomes and engagement during the instruction of perimeter and area. Materials and Methods. A quasi-experimental, mixed methods design was employed involving two intact seventh-grade classes (N=32) from a public school in Mitrovica, Kosovo. One class served as the experimental group, receiving instruction with virtual manipulatives, while the control group followed traditional methods. The intervention spanned two weeks and included pre- and post-tests, a student questionnaire, and an observation checklist. Quantitative data were analyzed using SPSS software, including paired and independent samples t-tests, while qualitative insights were gathered through observation. Results. The experimental group demonstrated significantly higher post-test scores compared to the control group (p =0 .005), indicating improved understanding of perimeter and area. Questionnaire results revealed high levels of motivation, enjoyment, and perceived learning benefits among students exposed to virtual manipulatives. Observation data supported these findings, showing increased engagement, collaboration, and positive behavioral changes. Conclusions. The findings confirm that virtual manipulatives positively influence students’ academic performance and attitudes in mathematics. They support both cognitive and affective domains of learning, offering an effective strategy for teaching geometric concepts. Further research is encouraged to explore long-term effects across broader student populations.Introducción. La incorporación de recursos digitales en la enseñanza de las matemáticas ha mostrado beneficios en la comprensión conceptual de los estudiantes. Los manipulativos virtuales, en particular, facilitan el razonamiento abstracto mediante entornos de aprendizaje interactivos y visuales. Objetivo. Este estudio tuvo como propósito evaluar el impacto del uso de manipulativos virtuales en los resultados de aprendizaje y en el compromiso de estudiantes de séptimo grado al abordar los conceptos de perímetro y área. Materiales y métodos. Se utilizó un diseño cuasi-experimental con enfoque mixto, involucrando a dos clases de séptimo grado (N=32) de una escuela pública en Mitrovica, Kosovo. Un grupo experimental recibió instrucción con manipulativos virtuales, mientras que el grupo control siguió métodos tradicionales. La intervención duró dos semanas e incluyó pruebas pre y post, un cuestionario estudiantil y una lista de observación. Los datos cuantitativos se analizaron con SPSS mediante pruebas t pareadas e independientes, complementados con observaciones cualitativas. Resultados. El grupo experimental obtuvo puntuaciones significativamente más altas en la prueba post- intervención (p = 0.005), lo que evidencia una mejor comprensión de los conceptos. Los cuestionarios reflejaron altos niveles de motivación, disfrute y percepción de aprendizaje. Las observaciones indicaron una mayor participación, colaboración y cambios de comportamiento positivos. Conclusiones. Los manipulativos virtuales demostraron ser eficaces para mejorar el rendimiento académico y las actitudes hacia las matemáticas, favoreciendo tanto los procesos cognitivos como afectivos. Se recomienda continuar investigando sus efectos a largo plazo en poblaciones estudiantiles más amplias.
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
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
