Lesson Two: Developing Expertise
Okay, you picked a project to work on. Great
job! Now you have to learn enough about the
subject so that you can work competently.
By competently I mean that you can work without
always having to look everything up.
It is vitally important to make sure that
you have the background necessary to do your
project. Of course there is no real way of
knowing, when you start out, where a project
will take your, or what knowledge you will
be required to have. This lesson helps you
develop the skills necessary to plan out
what background you will need to acquire
in order to do a project, and how to get
it.
Charting Your Course
The first step is to understand the problem
you chose in the last lesson. Can you define
the problem in a simple way, as if to a lay
person? If not then you need to start there.
Develop a definition of the phenomenon for
your project and another for the question
you have asked. Write these definitions down
somewhere. They may change over time, but
you have just developed the starting point
for your research.
Does your question itself suggest what sort
of information you will need to gather about
the phenomenon?
Beginning Your Project Notebook
There are three types of project notebooks.
The first is the most common, the laboratory
notebook. The second is also quite common,
the field notebook. The third is much rarer,
the theory notebook.
No matter what kind of notebook you choose
it should be a nice one. There is no reason
to skimp on important work, and even nice
notebooks are not terribly expensive. I like
bound sketchbooks, be sure to number each
page as you work through it. Never tear pages
out of a lab or field notebook since this
destroys the integrity of the data you are
preserving.
Much has been written about how to keep a
laboratory notebook and I will add to it
here:
- Title of the notebook: This should be the
title of the research project, or the question
you are asking.
- Table of contents: You should devote the
first couple pages to this and as you proceed
enter the names of sections and their page
numbers, experiments and their page numbers,
and significant results and their page
numbers.
- Make an introductory page where you note
the question and why you are intersted,
In
essence you are clarifying what you intend
to do with your project. This can be of
great
help to you later on. This is also a good
place to note additional questions that
arise
as you write the introduction.
- Each experiment should be titled and numbered.
- Write a brief description of the reason for
the experiment.
- Write an introduction to the experiment that
describes what makes the experiment interesting.
Describe the variable that you are interested
in measuring and how it fits into the sceme
of your project.
- Define your hypothesis, that is the statement
of what you expect to happen in the experiment.
- Describe the procedures you use as you perform
them. Record all data as it occurs. When
using automated systems record the location
of any files, and get printouts of all tabular
data. Be sure to include all units. Include
diagrams of circuits, glassware set-ups,
photos of instruments, etc.
- Record all calculations you perform and why.
- Record all results from calculations and
data analysis. Paste printouts right into
the notebook.
- Discuss the ramifications of the results
in the context of your project.
- Note your conclusions.
- Sign and date the results. If the experiment
goes across several days then sign and date
it at the end of each day and begin the next
session on a new page.
Field notebooks are almost identical to lab
notebooks except that you should also note
your position and the local conditions (temperature,
pressure, winds, etc.) that might be of interest
to your results.
- Title of the notebook: This should be the
title of the research project, or the question
you are asking.
- Table of contents: You should devote the
first couple pages to this and as you proceed
enter the names of sections and their page
numbers, experiments and their page numbers,
and significant results and their page numbers.
- Make an introductory page where you note
the question and why you are intersted, In
essence you are clarifying what you intend
to do with your project. This can be of great
help to you later on. This is also a good
place to note additional questions that arise
as you write the introduction.
- Each field session should be titled and numbered.
- Write a brief description of the reason for
the field session.
- Write an introduction to the field session
that describes what makes it interesting.
Describe what you are hoping to find and
how it fits into the sceme of your project.
- Describe the procedures you use as you perform
them. Record all data as it occurs. When
using automated systems record the location
of any files, and get printouts of all tabular
data. Be sure to include all units. Include
diagrams of circuits, glassware set-ups,
photos of instruments, etc.
- Record all calculations you perform and why.
- Record all results from calculations and
data analysis. Paste printouts right into
the notebook.
- Discuss the ramifications of the results
in the context of your project.
- Note your conclusions.
- Sign and date the results.
A theory notebook has no requirement for
preservation of the integrity of data so
there is no need to date things or make any
attempts to verify data. In fact many theorists
do not keep notebooks, they use file folders
and note pads. I recommend a notebook since
it prevents you from losing anything.
- To begin a theory project, clearly write
out your initial assumptions. Number each
so that you can refer to them later.
- Unless you are working in pure mathematics
you will be relating various physical quantities.
As you derive these relationships you must
note each step along with a justification
for each.
- When you search the literature for a definition,
conjecture, theorem, proof, or whatever;
reproduce it in the notebook with full
credit
for the source (I have been known to photocopy
such and tape the photocopy into the notebook).
Here is an important point, if you don't
understand something, don't use it.
- Whenever you do something, make a note of
what it was you did.
- Never throw away a negative result, it can
save you time later.
- Never throw out a mistake, it can save time
later.
- Whenever you generate computer output make
a note of the filename, make a backup of
it, and if possible make a hard-copy of it.
How to Get Current and Stay Current
Task List for this lesson:
- Develop a set of questions about your idea for a project. Write these down in your project notebook, perhaps numbering them for later reference. Answer each of these by using the steps below. Always immediately note all new questions that arise. Write the answers into your notebook. You may need to change an answer as you uncover new facts, so numbering the answers along with the questions is advised.
- The first place to look, assuming you do
not have experise in the subject of your
project, is a general-purpose encyclopedia.
My preference is Britannica, and since the electronic version is only
a little more than $100 (at least when I
bought my copy), there is no reason why you
shouldn't have it. It is a wonderful reference.
Use the techniques from the self-study course
to develop a knowledge base from the encyclopedia.
- Once you have exhausted a general encyclopedia
I would recommend supplementing that with
a technical/scientific encyclopedia. These
tend to be very expensive, but if you can
afford it, they are well worth it. My favorites
are: The McGraw-Hill Encyclopedia of Science and
Technology (which I have on CD-ROM, this cost over
$1,000), The Kluwer Encyclopedia of Mathematics on CD-ROM (all 10 volumes from the print
version and the Supplement volume I), the
second edition Encyclopedic Dictionary of Mathematics, the Amateur Scientist CD-ROM, the CRC Concise Encyclopedia of Mathematics, and other mathematical handbooks with numerous
articles. Again, use the techniques from
the self-study course to explore more deeply
the subject you have chosen.
- At this stage use the bibliographies of the articles you are reading to develop a list of authors for textbooks, monographs, audio-visual, and web-based information in your field.
- Search through the list and determine, hopefully
by direct examination, those materials you
find most useful and acquire them (either
from the Internet, a local library, or—most
desirably—through direct purchase).
- Learn to use the index and table of contents of your materials, if they are available, to look up the answers to your questions.
- Once you have exhausted the books that you have on the subject, then it is time to look in review journals and conference proceedings (and in some cases web pages). These sources will bring you rapidly up to date with what is currently being done in the field.
- Once you have a grasp of where things are in the field you have chosen it is time to look at current research papers. These can be found in research journals and often online.
- If you still have questions, now that you have a basis of expertise, contact a scientist working in the field. Many scientists are quite willing to discuss their work. Be sure to take notes or bring a tape recorder, you don't want to take up someone's time and have it wasted.
