This edited volume presents a systematic analysis of conceptual, methodological and applied aspects related to the validation of educational tests used in Latin American countries. Inspired by international standards on educational measurement and evaluation, this book illustrates efforts that have been made in several countries to validate different types of educational assessments, including student learning assessments, measurements of non-cognitive aspects in students, teacher evaluations, and tests for certification and selection. It gathers the experience of validity studies from the main international assessments in Latin America (PISA, TIMSS, ERCE, and ICCS). Additionally, it shows the challenges that must be taken into account when evaluations are used to compare countries, groups or trends of achievement over time. The book builds on the premise that measurements in the educational field should not be used if there are no studies that support the validity of the interpretation of their scores, or the use made of such tests. It shows that, despite the recognition given to validity, relatively few educational measurement assessments have accumulated enough evidence to support their interpretation and use. In doing so, this volume increases awareness about the relevance of validity, especially when assessments are key component of educational policies.

This book presents some of the leading technical, professional, and political challenges associated with the development and implementation of teacher evaluation systems, along with characterizing some of these systems in different countries around the world. The book promotes a broader comprehension of the complexities associated with this kind of initiatives, which have gained relevance in the last two decades, especially in the context of policies aimed at improving the quality of education. The first section of the book includes conceptual chapters that will detail some of the central debates around teacher evaluation, such as a) performance evaluation versus teaching effectiveness; b) tensions between formative and summative uses of evaluation; c) relationship between evaluation and teacher professionalization; and d) political tensions around teacher evaluation. In the second section, the book addresses specific examples of national or state-wide initiatives in the field of teacher evaluation. For this section, the authors have invited contributions that reflect experiences in North America, Asia, Europe, Oceania, and Latin America. In each chapter, a teacher evaluation system is presented, including their main results and validity evidence, as well as the main challenges associated with its design and implementation. This wide-ranging presentation of teacher evaluation systems around the world is a valuable reference to understand the diverse challenges for the implementation of teacher evaluation programs. The presence of conceptual chapters with others that illustrate how teacher evaluation has been implemented in different contexts gives the reader a comprehensive view of the complex nature of teacher evaluation, considering their technical and political underpinnings. It is a valuable source for anyone interested in the design, improvement, and implementation of teacher evaluation systems.

hombres que ame y se fueron. Como dijo Campoamor: El amor se transforma y no varia, un mismo amor puede tener mil nombres.

Tres poemas de tres amores vividos. El primero una tortuosa relaci-n entre una dama y un marginado social, el segundo a mi padre, verdadero amor de mi vida y el tercero a un amor de juventud. Incluye los poemas escritos por mi hijo, olvidados en un rinc-n.

Recopilacion de poemas que las experiencias vividas han sido escritas a lo largo de una vida. Reflexiones, dedicatorias y otros pensamientos.
