Resumen basado en el del autor

Overcoming difficulties with number : supporting dyscalculia and students who struggle with maths.

El autor subraya la importancia de comenzar con materiales concretos y manipulables, antes de pasar a materiales más simbólicos. Su enseñanza se basa en la comprensión actual del alumno, en lugar de en su rendimiento. Ofrece una gran cantidad de actividades y juegos numéricos con una gran variedad de materiales, incluyendo regletas de Cuisenaire y los dominós de las etapas más tempranas. A medida que los alumnos progresan se introducen razonamientos más complejos. Proporciona métodos muy claros para las áreas donde muchos niños tienen grandes dificultades con el concepto de número. Incluye Un CD-ROM que contiene todos los recursos que se describen en el texto, una versión imprimible de la guía y una lista de actividades para los padres.

Living geography : exciting futures for teachers and students.

Este recurso pensado para los profesores trata de inducir el pensamiento geográfico en los jóvenes y darles a conocer la utilidad del aprendizaje de la geografía. Para lo cual, el docente desafía a los alumnos con preguntas sobre sus vidas, su futuro y cómo están conectadas con otras personas y lugares, en una escala que va desde lo local hasta lo mundial. También, examina como la geografía se presenta en los programas de estudio de educación secundaria sobre la base de una forma de comprender el mundo.

Dyslexia in secondary school : a practical handbook for teaches, parents and students.

Este recurso centra su atención en la ayuda que puede darse en el aula a estudiantes disléxicos. Los profesores serán capaces de identificar a los niños con problemas específicos de aprendizaje y conocer mejor la forma de ayudarlos en sus tareas escolares. Los ejemplos se basan en el currículo y se utilizan para mostrar cómo aconsejar a los estudiantes en la redacción de ensayos, toma de apuntes, memorizar el vocabulario y la lectura para recordar. Contiene diagramas, mapas mentales, hojas de trabajo, así como muchas ideas para los profesores. Los métodos presentados como esenciales para estudiantes con dislexia, al centrarse en la manera en que se aprende, también ayudan a elevar el nivel académico de todos los alumnos en la escuela secundaria.

Libraries and literature in Rome

A chapter of 6,000 words on books, literary culture, and public and private libraries in the ancient city of Rome

Combinatorial peptide ligand libraries and plant proteomics: a winning strategy at a price

The mechanism of action and properties of a solid-phase ligand library made of hexapeptides (combinatorial peptide ligand libraries or CPLL), for capturing the "hidden proteome", i.e. the low- and very low-abundance proteins constituting the vast majority of species in any proteome, as applied to plant tissues, are reviewed here. Plant tissues are notoriously recalcitrant to protein extraction and to proteome analysis. Firstly, rigid plant cell walls need to be mechanically disrupted to release the cell content and, in addition to their poor protein yield, plant tissues are rich in proteases and oxidative enzymes, contain phenolic compounds, starches, oils, pigments and secondary metabolites that massively contaminate protein extracts. In addition, complex matrices of polysaccharides, including large amount of anionic pectins, are present. All these species compete with the binding of proteins to the CPLL beads, impeding proper capture and identification / detection of low-abundance species. When properly pre-treated, plant tissue extracts are amenable to capture by the CPLL beads revealing thus many new species among them low-abundance proteins. Examples are given on the treatment of leaf proteins, of corn seed extracts and of exudate proteins (latex from Hevea brasiliensis). In all cases, the detection of unique gene products via CPLL capture is at least twice that of control, untreated sample.

'The house of books': libraries and archives in Ancient Egypt

In 1957, John Sperry Jr. published an article in Libri entitled “Egyptian libraries: a survey of the evidence.” Some 55 years on, this article revisits the subject, taking into account research undertaken in the field of Egyptology over the last half a century. Based on an extended essay written for the online Certificate in Egyptology course at the University of Manchester, this article considers the evidence for the existence of “institutional” (that is, created for the use and functioning of the state) libraries and archives in Ancient Egypt throughout the dynastic period (c.3500−30 B.C.); their history, purpose and, to some extent, their administration. It also considers an aspect not explored in Sperry’s article, that of “private” libraries in Ancient Egypt (texts collected by an individual for their own personal use). Whilst estimated literacy levels within the general population precluded the widespread collection of texts for personal edification, there is evidence to suggest that private libraries were present in Ancient Egypt. The article concludes with a brief assessment of the legacy of these ancient libraries and their influence on the creation of the Library of Alexandria, in both its ancient and modern manifestations.

Using social networking tools for teaching and learning: a perspective of University lecturers and students

The use of online social networking tools (SNTs) has become commonplace within higher education. In this paper a definition and a typology of educational affordance of social networking service (SNS) are presented. The paper also explores the educational affordances whilst examining how university lecturers and students use SNTs to support their educational activities. The data presented here were obtained through a survey in which 38 participants from three universities took part; two universities in Uganda and one in the United Kingdom. The results show that Facebook is the most popular tool with 75 % of participants having profiles. Whilst most participants perceived the educational significance of these tools, social affordances remain more pronounced compared to pedagogical and technological affordances. The limitations of this study have also been discussed.

Libraries and networks of influence in the Roman world

This paper is concerned with the ways in which libraries – in this case public libraries in Rome and the Roman world – acted as points of connectivity and communication.

Bullied by Budgets, Pushed by Patrons, Driven by Demand: Libraries and Tantalizing Technologies

Libraries are caught in the middle—between static or shrinking budgets on one hand and ever-expanding user needs on the other. How did we get here, and where do we go from here? This paper will offer two perspectives: Part I will present survey results about changing Library purchasing habits in light of changing formats, access, business models and user demands. Data from a previous survey on this topic will be compared and updated. Pricing trends and possible futures will be discussed. Part II will briefly trace the history of libraries’ roles in scholarly communication and connecting learners with knowledge. From there, we show an example of phasing in a patron-driven / demand-driven and short-term loan e-book program, complete with incorporating these tools in library instruction, research, and portable device loadability for field work.

TRICUT: a program to clip triangle meshes using the rapid and triangle libraries and the visualization toolkit

An efficient technique to cut polygonal meshes as a step in the geometric modeling of topographic and geological data has been developed. In boundary represented models of outcropping strata and faulted horizons polygonal meshes often intersect each other. TRICUT determines the line of intersection and re-triangulates the area of contact. Along this line the mesh is split in two or more parts which can be selected for removal. The user interaction takes place in the 3D-model space. The intersection, selection and removal are under graphic control. The visualization of outcropping geological structures in digital terrain models is improved by determining intersections against a slightly shifted terrain model. Thus, the outcrop line becomes a surface which overlaps the terrain in its initial position. The area of this overlapping surface changes with respect to the strike and dip of the structure, the morphology and the offset. Some applications of TRICUT on different real datasets are shown. TRICUT is implemented in C+ + using the Visualization Toolkit in conjunction with the RAPID and TRIANGLE libraries. The program runs under LINUX and UNIX using the MESA OpenGL library. This work gives an example of solving a complex 3D geometric problem by integrating available robust public domain software. (C) 2002 Elsevier B.V. Ltd. All rights reserved.
