The Cornell System

During the past summer vacation I read at lifehacker.com an article titled "Geek to Live: Take study-worthy lecture notes". This article introduced me to the Cornell Note-taking method. I most say that although the Cornell method looked interesting, I wasn't sure about it's effectiveness. So, as a true scientist, I tested it over a whole semester.

The Cornell note-taking method was developed by Walter Pauk (1950s) in order to help students learn better. According to the method, a paper sheet is separated into three areas: the Notes area, the Cues area, and the Summary area. The Notes area, which is the largest, is for taking notes during the lecture. The other two areas are not to be used during lecture time. After the lecture, the student should (I made it bold because I barely now someone who actually does it) review their lecture notes. When doing so, on the Cues area important key-words or questions are to be written down and the whole page is to be summarized using a few (7-12) sentences in the Summary area. Much more information about the Cornell method can easily be find via Google.

To test the effectiveness of this method I created my own notebook, all pages printed from one of the many Cornell generators out there. I used this note book for my Cell Neurophysiology course. My way of taking notes during lectures is to write down everything the professor says, without trying to organize it too much or understand it; I like to record first, understand later. Since the Notes area is smaller then a regular notebook page size, each lecture took me about 6 pages. After the first lecture I kind of forced myself to review my notes and fill in the Cues and Summary areas. Turned out, that reviewing lecture notes using this system was much more pleasant and easy then usual, although Cell Neurophysiology is one the toughest mandatory courses for the Neuroscience program. After a few weeks I realized that the smaller Notes area was the trick. First, when looking at the page there was less text to read and therefore less intimidating. Second, I issued each page as one unit of notes to process, therefore I didn't try to summary and organize the whole lecture (which could take a long time) but rather one unit at a time; processing one page at a time. The Cues area was used by me to record names, dates and important key-words. Anything I wrote in the Cues area was written parallel to it's source in the Notes area, creating a sort-of index system where by looking in the Cues area for a key-word I can find the lecture notes regarding that word. In the Summary area I tried to summary each paragraph in the Notes area using one and only one sentence. Of course some paragraphs required more then one sentence, but on the other hand, some weren't worth summarizing at all.

Our Cell Neurophysiology course is really difficult. It requires understanding of molecular biology, chemistry and lots of physics (especially electricity). While most of my classmates struggled to keep up with the professor and understand what he is talking about, for me everything was clear. Using the Cornell system not only "forced" me to review my notes, but also to review them effectively.

A few days ago our test results arrived. Out of 146 students taking this course I scored the third highest score - 95, my highest score so far. I truly belief that the Cornell method helped a lot in gaining this high score. By reviewing and summarizing my lecture notes during the entire semester, and not only during the days before the exam, I earned a better understanding of the neurophysiology and therefore was able to ace the exam.

For the coming semester I've already decided that all my notebooks will be according to the Cornell method. All I need to do now is find a cheap way to print and bind all these notebooks.

The search for a milestone

One of the courses I took this semester is called "Milestones in Neuroscience". Although some may argue that it's not an important course, I really enjoy it. This course is the first that arranges all the information I learned in other courses in to a chronological order of events and points out the interconnections between them. Since it doesn't have a real syllabus, the lecture subjects are undetermined and mostly based on the on-going discussion held in class.

"If there is no syllabus, then on what will the test be?" was the first question asked during the opening lecture of the course. The answer was early to come -- "You shall write a paper about any topic you wish, as long as it's a milestone in Neurosciece". The race begun. Since that day, I've searched the Internet and read many articles looking for an acceptable milestone. unfortunately, none of the topics I suggested were accepted by the professor.

Since I come from the field of computers and have some very little experience with computer vision, I decided that the Nobel Prize research on the mechanisms of vision could be a suitable topic. However, this topic wasn't acceptable---not because it's not a milestone, but because the professor wanted to dedicated a lecture for discussing this discovery. So, I continued to search around, and came across an article about the Allen Brain Atlas project. This topic was also not accepted in the claim that it's contribution to neuroscience is undetermined yet (because it's too new). Turns out, this paper will be harder then I thought! Still trying to stay somewhat related to computers, I wanted to write about the contribution of computer science to vision research. I spent more than 6 hours reading various articles, blogs, and web-pages, just to get to the realization that it's hard to count it as a milestone.

I almost gave up on finding a subject for my paper. And then there was neurophysiology! During one of our lectures in neurophysiology, the professor talked about the invention of cellular fluorescent painting (FURA-2). That day, while reviewing my notes, I knew I found my milestone. From reading on the Internet about FURA-2, I landed on the Wikipedia page about GFP.

Green fluorescent protein (GFP), is a protein that exhibits green fluorescent light when exposed to blue light. Although there are many fluorescent proteins, this jellyfish isolated protein is unique in that it is able to enter the genome. Therefore, a researcher can paint the genome of one mouse and all it's children will be automatically painted as well. This is very useful for tracking genetic patterns. Basically, GFP is a very popular method.

Right now, I don't know too much about GFP but it was accepted by my professor as a topic for my paper. Now I need to read more about it and find some articles that will be accepted as references of the paper. Hopefully, finding the right articles will be easier than finding the right topic. I'll update on this assignment later on another post.

Two worlds

Well, I know i didn't blog for a very long time but i'm sure I have a really good reason for that - I'm a student. right now I'm in the middle of my exam period and it's really frustrating, all these exams one after another, it's really hard. I think the worst thing about all these exams is also the thing i like most about what i'm studding - the inter-disciplines. I have two majors: brain science and computer science. I must say that both are very interesting, however sometimes it's a bit awkward. For example, this week i have two different exams, one in Data-Structures and the other in Biology of the Cell, two days apart, WTF! So i need to study for both exams together, half a day for one exam and half a day for the second one. sounds easy but shifting my mind from a mathematical state to a biological isn't so easy. hope it will become better next semester.

Welcome

The first week of my college education is over and it was very interesting but at the same time, raised a few problems I hadn't anticipated.

For example, the issue of time management .
Learning about 50 hours a week is difficult and real time consuming.  I found myself struggling to find time during the day to eat, and when I arrived home, I always found myself busy until after midnight, knowing that I need to wake up the next day at 6:00AM.  This weekend I realized I need a good time management plan so I could sleep, eat & study well without any pressure.

The food is another problem I encountered this week.
Apparently, one sandwich for 8 hours just isn't enough.  I was hungry the whole week, and even lost about 2Kg this week for not eating correctly.
In terms of food, my plan for the coming week is to have a good breakfast in the morning, 3 sandwiches during the day and healthy dinner with meat and a salad for dinner.  Hopefully this diet will give me all the energy I need to be able to concentrate up to 12 hours a day in lectures.

The first semester of a Brain Science Freshman's year consists of introductory courses in: Biology, Chemistry, Psychology, Programming, Philosophy, and Brain Science.  Of course there's also a number of mathematics courses at a much higher level then what is taught in high-school.

It was very interesting to learn this week how the brain developed and why  it developed in the head?  If the brain is so important it should have been kept somewhere safer than the head, just as the heart is kept safe under the ribs.  It turned out that the brain actually developed in the head because ancient marine organisms developed sensor cells at the front of their body to know what is ahead of them, food or danger, so they could act.  In evolution, those cells developed to be the brain we all have in our head.

Take Off

The last day of vacation is over and tomorrow I start a new part of my life.
Tomorrow I start my college education at the Bar-Ilan University in Israel, as a Brain Science student.


I am ready for studying! I've bought myself a new backpack, 12 notebooks, a calendar, and set a side half a dozen pens.  This year I will be studying introductory courses in a number of disciplines, including Math, Biology, Chemistry, Computer Science, Linguistics and Brain Science.  All these introductory courses are to give the basic knowledge in order to really start studying about the human brain in the second year.

Although I'm expecting a difficult year, I hope I'll enjoy the complexity of the studies and the variety of disciplines.

It's quite ironic that my first day of college is on my 22nd birthday.  I hope that is a good sign.
