For those who does not know it, TED-Ed is the "educational branch of TED". Instead of lectures, they create and share "lessons that worth spreading". I have already contributed to TED-Ed with the lesson The last banana: A thought experiment in probability.
This weekend I discovered Boavista, a portuguese restaurant in Nottingham.
It is a pretty simple place, with a portuguese ambiance (much louder than a British restaurant, with TVs showing portuguese shows, and people talking in portuguese) and very good options. I tried the bacalhau a Gomes Sá, a traditional Portuguese dish with salted cod, potatoes, onion, eggs and lots of olive oil. My girlfriend tried spare ribs. Both dishes were very well done and following the Portuguese style of cooking (no sauce on the ribs, for instance).
But the real climax were the dessert: Portuguese custard tart (I cringe just by using custard to describe the filling of these tarts... it is much more than custard!). It was absolutely delicious.
And, to crown the visit, a very good espresso. I would not say it is the best coffee in town (as they state in the front show windows), but it is very very good.
This paper presents some theoretical arguments that I am developing for my thesis as a result of preliminary analysis of my data.
Abstract: In this paper, I will present some implications of Marcus Giaquinto’s ideas about visual thinking and its epistemology when combined with Toulmin’s layout of an argument. This is the result of an ongoing effort to discuss, from a theoretical perspective, some issues that emerged from my Ph.D. research about teaching and learning addition and subtraction of fractions to low achieving students. My claim is that visual representations can be effective for low achieving students when teaching is focused on a carefully chosen model and time is given to students to fully use it.
