Category : Education
Languages : en
Pages : 309
Book Description
Análisis de los datos de una evaluación nacional del rendimiento académico es el cuarto de cinco volúmenes de la serie Evaluaciones nacionales del rendimiento académico. Otros volúmenes han descrito los procedimientos de una evaluación hasta llegar a la fase de preparación de los datos para su análisis estadístico, el tema del presente volumen. Los análisis precisos que se lleven a cabo dependerán de las necesidades de información de los responsables políticos y los gestores educativos. En la mayoría de las evaluaciones nacionales, estas necesidades tienen que ver con la calidad del aprendizaje estudiantil, los factores relacionados con el aprendizaje, las cuestiones de equidad, y en algunos casos, la transformación de los resultados educativos con el paso del tiempo. El volumen 4, que consta de dos partes, explica detalladamente los pasos necesarios para el análisis de los datos recopilados en una evaluación nacional. La 1.ª parte ofrece una introducción general a los análisis estadísticos llevados a cabo normalmente en las evaluaciones a gran escala, midiendo la tendencia central y la dispersión de los puntajes de los alumnos, así como las relaciones entre variables. La 2.ª parte describe el programa IATA (Item and Test Analysis), que utiliza la Teoría Clásica de las Pruebas y la Teoría de Respuesta al à?tem para establecer escalas sobre las que determinar los puntajes de los alumnos. Se describe en detalle los pasos del análisis de las administraciones de las pruebas piloto y las pruebas definitivas. Un CD complementario contiene ejercicios especialmente diseñados y ficheros de datos de respaldo para ambas partes del volumen. Este libro será de interés para los especialistas en evaluaciones en gobiernos nacionales, regionales y locales, instituciones de investigación y universidades.

Languages : en
Pages : 305
Book Description
Implementing a National Assessment of Educational Achievement, the third volume in the five-part National Assessments of Educational Achievement series, focuses on practical issues in the implementation of a national assessment. These include the representation of key educational stakeholders, required personnel and facilities, and the sequence of administrative activities in implementing an assessment. Particular attention is focused on sampling, such as defining the population to be assessed, elements of sampling theory, and the selection of schools and students to take part in an assessment. Readers are guided through the selection of a sample by working on a set of concrete tasks presented in the text, using data files in an accompanying CD. One section of Volume 3 is devoted to typical tasks involved in preparing, validating and managing data. Users are expected to develop competence in data preparation skills by carrying out the practical exercises in the CD. They are also shown how to complete important pre-analysis steps such as compute survey weights, calculate means and their sampling errors, and how to deal with non-responses and oversize and undersize schools. This volume is intended primarily for teams who are responsible for conducting national assessments and graduate students interested in technical aspects of large-scale surveys.

Book Description
This innovative book proposes new methodologies for the measurement of entrepreneurship by applying techniques of demography, engineering, mathematics and statistics. Using the data from the Global Entrepreneurship Monitor (GEM), statistical demographic techniques are used for the evaluation of data quality (EDQ), and a new methodology for the estimation of Specific Entrepreneurship Rates (SER) and the Global Entrepreneurship Rate (GER) is proposed. At the same time the authors present artificial intelligence techniques such as Fuzzy Time Series (FTS) to forecast data series of the entrepreneurial population. Finally, they present a case study of the implementation of Big Data in Entrepreneurship using GEM data that shows the latest technological trends for the management of data, in support of making more accurate decisions. Being a methodological book, the techniques presented can be applied to any dataset in different areas. Readers will learn new methodologies of analysis and measurement of entrepreneurship using data from the Global Entrepreneurship Monitor. They will be able to access the experience of the authors through each of the applied cases in which the reader is taken by the hand, both through the scientific method and through the methodology of construction of more accurate metrics in entrepreneurship, with less error. This book will be of value to students at an advanced level, academics and researchers in the fields of Entrepreneurship, Business Analytics and Research Methodology.
