El presente artículo analiza las trayectorias de los miembros de tres centros de investigación en México. Para ello se recurre a dos categorías analíticas que se yuxtaponen en las prácticas ...cotidianas: trayectoriasy experiencias. A través de ellas se analiza el sentido atribuido al papel de la ciencia en la sociedad como uno de los pliegues de las subjetividades científicas. La hipótesis es que las trayectorias definen modos de hacer ciencia y esto a su vez configura un sentido al trabajo de investigación, una disposición del papel de la ciencia en la sociedad. La investigación se basó en el método biográfico en donde se da centralidad a las entrevistas en profundidad. La apuesta metodológica se complementó con la revisión documental y el análisis de los curriculum vitæde los científicos entrevistados.
Esta investigación analiza el contenido didáctico de los libros de texto de Historia de México a nivel bachillerato. Se empleó una metodología cualitativa de tipo descriptivo. El uso del Análisis del ...Discurso (AD) permitió identificar el contexto político, económico y educativo bajo el cual se definen los contenidos de los libros de texto, así como de la participación de editoriales extranjeras que forman parte en este proceso y cuya intervención en la creación de contenidos es también fundamental. Se concluye que, los libros de texto de la asignatura, representan un discurso nacionalista más que didáctico. Con base en la información analizada, se propone un currículo que desarrolle en el alumno las habilidades necesarias para lograr una empatía histórica y un conocimiento significativo.
A randomized-trials design was used to evaluate the effectiveness of a preschool mathematics program based on a comprehensive model of research-based curricula development. Thirty-six preschool ...classrooms were assigned to experimental (Building Blocks), comparison (a different preschool mathematics curriculum), or control conditions. Children were individually pre-and posttested, participating in 26 weeks of instruction in between. Observational measures indicated that the curricula were implemented with fidelity, and the experimental condition had significant positive effects on classrooms' mathematics environment and teaching. The experimental group score increased significantly more than the comparison group score (effect size = 0.47) and the control group score (effect size = 1.07). Early interventions can increase the quality of the mathematics environment and help preschoolers develop a foundation of mathematics knowledge.

A thoughtfully constructed syllabus can be transformative for your students' learning, communicating the path they can take to succeed. This book demonstrates how, rather than being a mundane ...document to convey policies, you can construct your syllabus to be a motivating resource that conveys a clear sense of your course's learning goals, how students can achieve those goals, and makes evident your teaching philosophy and why you have adopted the teaching strategies you will use, such as discussion or group activities. Developing or revising a syllabus also presents you with a perfect opportunity to review the learning possibilities for the semester. Well-designed, it can help you stay focused on achieving the learning outcomes, as well as determine if the class is on track and whether adjustments to the schedule are needed. The authors show how, by adopting a welcoming tone and clearly stating learning outcomes, your syllabus can engage students by explaining the relevance of your course to their studies, create an all-important positive first impression of you as an instructor, and guide students through the resources you will be using, the assignments ahead, as well as clear guidance on how they will be assessed. Referred to frequently as the course progresses, an effective syllabus will keep students engaged and on task.Christine Harrington and Melissa Thomas lead you through all the elements of a syllabus to help you identify how to present key messages and information about your course, think through the impressions you want to create, and, equally importantly, suggest how you can use layout and elements such as images and charts to make your syllabus visually appealing and easy to navigate.

In this article, we present a study of certain aspects of the mathematical knowledge for the teaching that teachers possess about the concept of measurement estimation. We study how teachers define ...and apply this concept which has been recently introduced in the Chilean curriculum and on which teachers have not received specific training. A survey was applied to 112 in-service teachers in their continuing training in Santiago de Chile. By means of a qualitative-descriptive analysis, we noted that the disciplinary knowledge on the concept of measurement estimation is poorly developed; teachers do not know the key aspects of the measurement estimation and confuse it with other measurement activities such as measurement with non-standard units.
