Just like representations in everyday life, this book shows that representations are ubiquitous to science, technology, engineering, and mathematics—the STEM disciplines.“Show Me What You Know” showcases research on representations across a range of STEM disciplines and ages—from children as young as 2 years of age to professional mathematicians. The text highlights the importance of paying close attention to learners’ interpretations and productions of different representations as a source of evidence for what learners understand, and another way for learners to “show us what they know.” The text is organized around four themes: appropriation of representations, making meaning...
En una sociedad en donde la ciencia está cada vez más presente en la vida cotidiana, parece necesario hacerla accesible a la mayor parte de los alumnos. No obstante, muchos datos revelan que éstos, en vez de asimilar las teorías y modelos científicos enseñados en clase, siguen interpretando el mundo según esquemas intuitivos o culturales ajenos a la ciencia. Por otra parte, cada vez hay más profesores de ciencias que comprueban, con frustración, que sus estudiantes apenas están interesados en ese saber científico y tienen también serias dificultades para utilizarlo en la resolución de problemas escolares o cotidianos. La respuesta a esta crisis de la educación científica debe ...
This open access book explores commentaries on an influential text of pre-Copernican astronomy in Europe. It features essays that take a close look at key intellectuals and how they engaged with the main ideas of this qualitative introduction to geocentric cosmology. Johannes de Sacrobosco compiled his Tractatus de sphaera during the thirteenth century in the frame of his teaching activities at the then recently founded University of Paris. It soon became a mandatory text all over Europe. As a result, a tradition of commentaries to the text was soon established and flourished until the second half of the 17th century. Here, readers will find an informative overview of these commentaries comp...
Multisim is now the de facto standard for circuit simulation. It is a SPICE-based circuit simulator which combines analog, discrete-time, and mixed-mode circuits. In addition, it is the only simulator which incorporates microcontroller simulation in the same environment. It also includes a tool for printed circuit board design. Advanced Circuit Simulation Using Multisim Workbench is a companion book to Circuit Analysis Using Multisim, published by Morgan & Claypool in 2011. This new book covers advanced analyses and the creation of models and subcircuits. It also includes coverage of transmission lines, the special elements which are used to connect components in PCBs and integrated circuits. Finally, it includes a description of Ultiboard, the tool for PCB creation from a circuit description in Multisim. Both books completely cover most of the important features available for a successful circuit simulation with Multisim. Table of Contents: Models and Subcircuits / Transmission Lines / Other Types of Analyses / Simulating Microcontrollers / PCB Design With Ultiboard

Perspectives on Knowledge Management The unprecedented developments in Information and communication technologies resulted in the speedy transition of the Industrial society into the Knowledge Society. Now the efficiency in knowledge Management determines the quality, speed and Development in all spheres of human activity. Experts from different academic disciplines have contributed to the growth of this innovative domain of knowledge as well as to the methods and techniques for managing it. Digital technologies make it possible to transfer or access knowledge transcending the limitations of space and time. Knowledge Management processes have started to get much importance along in the manuf...
The main purpose of the CTS education is to promote literacy in science and technology so that the citizens can participate in the democratic process of the taking of decisions and to promote civic action in the resolution of problems related with science and the technology in our society.
