A MR Imaging primer through analogy with Guitar playing

Thanks to my colleague Jerry Battista from the University of Western Ontario, understanding the basic MR pulse sequence (a not so obvious topic especially if you have to design such a sequence) is now easier than ever. For those who do not know Prof. Battista also developed a mini-CT scanner (using non-ionizing radiation!) to teaching the basic of medical imaging from high-school all the way to university. We are using this scanner in our undergraduate laboratory.


So, check out this wonderful and accessible teaching YouTube Video: Understanding an MRI Pulse Sequence using a Guitar.

Zoom to Yosemite and iOS8 versions, and I must say that not only do Keynote, Numbers and Pages are now greats apps, but there actually work extremely well both on the desktop and on the iPad (I do not really use these apps on the iPhone).

Exams vs Learning or Yin vs Yang?

Not so long ago, we were having an open exchange among the Faculty of our department on learning and evaluating how new concepts were acquired by students. In particular, we exchange on the value of frequent testing (quizzes) versus the famous “finals”. This interesting  article was pointed out to me Tests That Teach | Arts & Sciences (and of course this always interesting Sir Ken Robinson on Ted Talks, about creativity and the fear of making mistake e.g. exams!), which seems to indicate that the type of exams, and their frequencies, you used in your class is impacting learning…

Diversity in evaluation methods used in probably the key in both being able to gage the level of understanding and knowledge retention of students and, at the same time, make sure that each and everyone can also get frequent feedback in order to apply course corrections…
