The most important thing to teach - BLOG ENTRY 2


In my opinion, one of the most important things to accomplish while teaching my subject is to make my pupils see the importance of the knowledge that I’m sharing with them and its application to real life. This is something that I’m already doing now with all the curriculum restrictions and I would reinforce it if I were free to design my own curriculum.
Although Maths is a subject that has some areas of knowledge which are plenty of real life examples and applications, there are also many other areas which are not properly covered in this way. In fact, even those that have clear applications are not usually exercised in a real context or with communicative practices.
So that, I would like to teach my subject with a proper reorganization of the contents along the different courses which let me include more real life practices and more group activities. This would be a great way to promote a subject that students usually are afraid of and a fantastic method to improve and promote communication and language practice too. 
 Under this approach, the evaluation could be focused on how students try to find and solve problems (alone but also as part of a group) interacting with other students and confronting real life situations where acquired knowledge must be applied.

PHI, The Golden Ratio


After my previous post, you already know that I love everything related with numbers and especially those facts that combine numbers and real life.



So that, today I want to write a few lines about another very important number in our lives although maybe it is not recognized by as many people as it happens with Pi. I'm talking about PHI, also known as the "golden ratio". Another irrational number with a great presence into the Nature, but also used by sculptors, painters and architects since many centuries ago.

In fact, its name comes from the famous artist and architect Phidias who built the Parthenon in the Ancient Greece, a building where golden ratio is present almost everywhere.



We find the golden ratio when we divide a line into two parts so that the longer part divided by the smaller part is also equal to the whole length divided by the longer part.


Many artists and architects believe that Golden Ratio makes the most pleasing and beautiful shape of a rectangle. There are even scientific studies which demonstrates that most of the people perceives this proportion as more beautiful than other ones.



By the way, one of the most famous series of numbers (Fibonacci series) is based in the golden ratio because each number of the series is the sum of the two numbers that precede it. This series floods Nature:

  • Many flowers have a number of petals that belongs to Fibonacci series.
  • Sunflower seeds follow spiraling patterns and each spiral is a number of this famous series.
  • Something similar happens with pinecones and their seed pods.

      
    We can also find this amazing ratio at snail shells, nautilus, the cochlea of our inner ear and spiral galaxies. Even in destructive forms… just have a look at satellite pictures of a hurricane and you will see that harmonious spiral inscribed into imaginary golden ratio rectangles. But this is just a small piece of the cake, next post I will write about human body (face, fingers, the Vitrubian man…), animal bodies, reproduction, DNA molecules.


    Don’t you think it’s an amazing relationship between Maths and Nature?

The Best Teacher I've Ever Had



Education is a very important part of our lives, not only for what our future refers, but also because it forms us as a person. Furthermore, we dedicate a very important part of our infancy, adolescence and youth to it. Because of it we guard many recollections of this and of the persons who have taken part in our training, especially of those that more impressed us for any reason, or simply because we admire their way of being.

In my case, I will always remember my teacher Verónica, the best teacher of mathematics that I have had and better person. The first day that I knew her, it was so funny that she was called like me. Later, she was my teacher of this subject for 3 years. She not only helped me to understand this matter in its more difficult areas but in addition she was a great emotional support to me. To be honest she was very strict in class, but always she was worrying for each and every of her pupils, independently about our notes or about our behavior.

I am not the only one who remembers her as the best teacher of the world. When we met the class mates, the teacher Verónica always is one of the major topics of our recollections. In fact, a couple of years ago, after having lost contact with her because she changed her city of residence, we returned to talk with her because some of their students organized a surprise visit in order to see her another time. I will never forget her tears when she saw us appearing for the door of the high school in which she is employed nowadays. Since this day, we are in contact through e-mail and we can talk about our similar lives. She continues being the best teacher of the world!
