The gamsin, negtan, and cosvnx from the Onion article are fictional, but the piece has a kernel of truth: there are 10 secret trig functions you’ve never heard of, and they have delightful names like “haversine” and “exsecant.”
Edgar Mata's insight:
10 funciones trigonométricas que no conocías: exsecante, haverseno, entre otras.
La derivada es una poderosa herramienta matemática. Nos permite enfrentar exitosamente problemas que, sin esta herramienta, pueden resultar demasiado complejos o, incluso, imposibles.
Edgar Mata's insight:
Al realizar el análisis del problema, suelen producirse intentos, cálculos, gráficas, y otros recursos, a veces, desorganizados. Con la finalidad de ordenar el procedimiento y los productos mínimos que conducen al resultado, se propone el siguiente formato.
Qué libro se publicó o fue publicado el mismo año de tu nacimiento
Edgar Mata's insight:
Grandes libros que debemos leer.
Cada año se escriben cientos de libros, pero sólo unos pocos pueden considerarse grandes libros. En esta página se publican comentarios y curiosidades acerca de los libros, en esta ocasión, organizaron los grandes libros por año de publicación, de modo que podemos saber cuáles grandes libros se publicaron en cualquier año, por ejemplo, el año en que nacimos.
The philosophy behind Problem-Based Learning is that knowledge and skills are acquired through a progressive sequence of contextual problems, together with learning materials and the support of the instructor. Its core lies in collaboration, as well as in personal reflection, as one of its main objectives is to foster independent and lifelong learners, where, however, teamwork substantially affects the quality of the work generated.
As a form of active learning, Problem-Based Learning encourages knowledge construction and integrates school learning with real life dynamics, where learners learn how to develop flexible knowledge, and effective problem-solving skills, acquire intrinsic motivation, exchange ideas and collaborate. Through collaboration, learners are able to identify what they already know, what they need to know, as well as the way and the source of information they need, to successfully reach to the solution of the problem. Instructors facilitate learning, by supporting, guiding and monitoring their learners’ progress, building their confidence, encouraging them to actively participate and stretching their comprehension. This method gives learners the opportunity to master their problem-solving, thinking, teamwork, communication, time management, research and computing skills.
This five-domain rubric was created, not for evaluation purposes (there are enough evaluation rubrics out there!), but for teachers to be able to self-assess, set goals and progress. In the same way, we want blended learning to allow for students to have a better understanding of their own strengths and weaknesses, we want teachers to be able to identify blended specific skills and better understand their own strengths and areas for growth. We wanted to give teachers, their coaches, and their leaders, a sense of what to strive for, and help them plot a path to get there through aligned professional development. We also found that the teachers we work with cherish the opportunity to self-reflect, identify the skills they have and the skills they need, and take the time to set goals around where they want to shift their practice. Many of our schools infuse these concepts into community of practices discussions for continuous learning.
Si ya tienes una edad, al ver esto desearás que algo así hubiera existido cuando ibas al colegio. Se llama PhotoMath y es una aplicación gratuita que resuelve problemas matemáticos con la cámara del móvil.
Today I have a short chat with some of my colleagues over the notion of concept mapping versus traditional outlining after which I decided to compile this list and share it with you here. Brainstorming ideas be it through concept maps or outlines is a scaffolding process that helps you flesh out relevant thoughts to include in your writing piece. On a personal level, I prefer to use outlines when I am engaged in an extensive writing project such as thesis writing or a literature review. Conversely, I feel more inclined to use concept maps with medium to short writing projects like writing a formal/informal essay, a long blog post, an article ...etc.
Concept map tools such as the ones below are useful for integrating in classroom instruction. You can probably use them with students to help them brainstorm ideas for their writing assignments or to crowdsource ideas around a given topic. I have gone through the tools available out there and handpicked for you this collection.
