En la actualidad, la práctica de la enseñanza se sigue apoyando mayoritariamente en el libro de texto, aun cuando existen múltiples recursos educativos y avances tecnológicos. La naturaleza, características y formato de un texto escolar de matemática, dependen de varias condiciones y variables de contexto, las cuales tendrán impacto finalmente en el proceso de enseñanza y aprendizaje de la disciplina. Este artículo da cuenta de uma investigación cualitativa, cuyo objetivo es describir el uso y los indicadores de apreciación que tienen los docentes de la enseñanza secundaria, en su calidad de usuarios de los libros de textos, distribuidos a todos los establecimientos educacionales públicos por el órgano oficial. De acuerdo a los resultados, se verifica a la adecuación y calidad de los recursos didácticos en matemáticas, como la característica de mayor satisfacción de parte de los docentes y predominan para su trabajo en aula, los libros de carácter expositivo y tecnológico, y en menor grado, el de carácter comprensivo.
Research in mathematics education has shown that individuals' beliefs play a fundamental role in their responses to and interest in mathematics and their application of these beliefs in real-life situations. Although the literature related to the affective domain in general, and beliefs in particular, has explored the relationship between beliefs and student educational level, there still needs to be a research gap regarding the empirical testing of this variable in the context of secondary mathematics education in Chile. Therefore, the present study, with a quantitative and exploratory methodology, aims to fill this gap by adapting the Mathematics-Related Beliefs Questionnaire MRBQ to describe and analyze students' beliefs in mathematics at two levels of secondary education. The main results of the study indicate that mostly positive beliefs are observed in the three types of beliefs studied: Beliefs about the social context, about self-concept, and mathematics education, highlighting the dimension of beliefs about the social context or classroom environment, in which students showed a highly positive perception of the role of the mathematics teacher.
BackgroundAccording to the Psychometric Paradigm with the appropriate design of instruments, risk perception can be measured; only ‘The Perception of Risk Scale’ in English, was found about this theme. The aim of this study was to develop and pilot test the validation of an instrument ‘Parents’ Risk Perception about Children’s Injuries’, in Spanish.MethodsComprised on a series of steps: 1. Literature review of the theme and previous instruments. 2. Initial development of items. 3. Application of Content Validity Analysis (CVI) (McGartland, et al., 2003). 4. Final proposal of instrument, 102 items, in 12 dimensions some with sub-dimensions. 5. Cronbach’s Alpha sample calculation, for the development of a new scale is acceptable a range of 24 to 36 participants (Johanson & Brooks, 2010). 6. Definition of sample population and criteria. 7. Design of the instrument, created for an optic reader. 8. Application of the instrument and consent form. 9. Data analysis, on Excel 2010 and SPSS 19.ResultsThe CVI sample was five professional and five lay experts, results meet the values for new instruments with CVI=0.911. For Cronbach’s Alpha, the sample consisted on 15 mothers and 14 fathers with at least one children under 16 years old, obtained by convenience. The result for the whole instrument was α=0.894. After eliminating 18 items, α=0.901; leaving the instrument with 84 items.DiscussionFor reducing the scale and making it more convenient, using the Spearman-Brown prophecy, assuming that the quality of the questions is the same, the instrument is reduced to 42 items and the Cronbach’s Alpha falls to an acceptable level of α=0.82.ConclusionThe scale was not validated, only an exploratory study was developed, the next step would be to redesign and apply again a pilot test, if successful continue with validation.
Este artículo tiene por objetivo presentar la experiencia de una institución de educación superior, a través de los resultados de la implementación de un modelo de dirección estratégica, investigando el impacto que presentan las etapas de análisis, formulación e implementación de este modelo para el periodo 2006-2017, 11 años. Para ello, en primer lugar, se desarrolla el marco teórico y, en segundo lugar, se expone la metodología de estudio de caso con el modelo de dirección implementado, al igual que la hipótesis y variables de investigación sobre las cuales se aplica posteriormente un análisis descriptivo, exploratorio, no experimental y se construye un modelo de ecuaciones estructurales (PLS-SEM). Los resultados de la investigación arrojan valores de R2 de 79,2% y 94,9%, verificando que la etapa de análisis estratégico impacta positivamente en la etapa de formulación e implementación que posee el modelo de dirección utilizado. Finalmente, se concluye que es relevante emplear un modelo que permita guiar a las instituciones de educación superior.
