La incorporación de la conjetura y el contraejemplo
Es bien sabido que en el aprendizaje de la Matematica, estan involucrados varios fenomenos de indole compleja que se presentan en todos los niveles educativos. Uno de tales fenomenos didacticos vertebrales, es el que se refiere a la estructuracion de un pensamiento matematico en los estudiantes. Es entonces pertinente plantear la pregunta: La incorporacion del uso del contraejemplo y la conjetura posibilita que los estudiantes transiten de un pensamiento ingenuo a un pensamiento matematico? Este trabajo analiza desde una perspectiva epistemologica y cognitiva, el papel que juega la incorporacion de estos recursos cuando se pretende instalar algunos de los conceptos fundamentales de la Matematica escolar, asi como la resolucion de problemas.
Handbook of Research on the Psychology of Mathematics Education
Compilation of the research produced by the International Group for the Psychology of Mathematics Education (PME) since its creation in 1976. The first three sections summarize cognitively-oriented research on learning and teaching specific content areas, transversal areas, and based on technology-rich environments. The fourth section is devoted to the research on social, affective, cultural and cognitive aspects of mathematics education. The fifth section includes two chapters summarizing the PME research on teacher training and professional life of mathematics teachers.
The Pan American Games / Los Juegos Panamericanos
The Pan American Games, second only to the Olympics as the biggest international sports competition in the world, are held every four years (during the year prior to the Summer Olympics) under the sponsorship of the International Olympic Committee. This book lists the results of the Pan American Games from their commencement in 1951 through 1999. Los Juegos Panamericanos, los segundos mas importantes del mundo tras los Olimpicos, se han venido celebrando cada cuatro anos desde 1951. Se incluye en el presente trabajo bilingue un recuento de los resultados reflejados en dichos juegos a lo largo de su historia, desde los comienzos hasta los mas recientes, celebrados en 1999.
Signs of the Inka Khipu
In an age when computers process immense amounts of information by the manipulation of sequences of 1s and 0s, it remains a frustrating mystery how prehistoric Inka recordkeepers encoded a tremendous variety and quantity of data using only knotted and dyed strings. Yet the comparison between computers and khipu may hold an important clue to deciphering the Inka records. In this book, Gary Urton sets forth a pathbreaking theory that the manipulation of fibers in the construction of khipu created physical features that constitute binary-coded sequences which store units of information in a system of binary recordkeeping that was used throughout the Inka empire. Urton begins his theory with the...
Developing Primary Mathematics Teaching
How can KS1/2 teachers improve their mathematics teaching? This book helps readers to become better, more confident teachers of mathematics by enabling them to focus critically on what they know and what they do in the classroom. Building on their close observation of primary mathematics classrooms, the authors provide those starting out in the teaching profession with a four-stage framework which acts as a tool of support for developing their teaching: - making sense of foundation knowledge - focusing on what teachers know about mathematics - transforming knowledge - representing mathematics to learners through examples, analogies, illustrations and demonstrations - connection - helping learners to make sense of mathematics through understanding how ideas and concepts are linked to each other - contingency - what to do when the unexpected happens Each chapter includes practical activities, lesson descriptions and extracts of classroom transcripts to help teachers reflect on effective practice.

This book is a complete guide to the C4.5 system as implemented in C for the UNIX environment. It contains a comprehensive guide to the system's use, the source code (about 8,800 lines), and implementation notes.
Vegetation Monitoring
This annotated bibliography documents literature addressing the design and implementation of vegetation monitoring. It provides resources managers, ecologists, and scientists access to the great volume of literature addressing many aspects of vegetation monitoring: planning and objective setting, choosing vegetation attributes to measure, sampling design, sampling methods, statistical and graphical analysis, and communication of results. Over half of the 1400 references have been annotated. Keywords pertaining to the type of monitoring or method are included with each bibliographic entry. Keyword index.
Drug Trafficking, Corruption and States
Drug Trafficking, Corruption and States is cutting edge research. Garay Salamanca and Salcedo-Albarán, along with their contributing authors help document the transition from economic to political imperatives within transnational drug cartels. The break from the Zetas by La Familia Michoacana is one example contained in their empirical survey. Social Network Analysis is their tool for illuminating the varying dynamics of cartel-state inter-penetration and reconfiguration. In doing so they clearly discern between State Capture (StC) and Co-opted State Reconfiguration (CStR). As the drug wars and criminal insurgencies rage in the Americas and beyond, this seminal framework will facilitate efforts by scholars, law enforcement officials, intelligence analysts and policymakers to understand shifts in sovereignty, and to illuminate the mechanisms of transnational illicit networks and their interaction with the state.
