Here are some suggestions on how to study physics (as well as other sciences).
Iím not offering you a guaranteed "A" with these hints, but after many
years of teaching (and gathering ideas from other teachers and students)
I do think these hints will help. Since each of us learns differently
some of these ideas may not be great for you. Also, if you feel comfortable
with your current study habits, continue them- if it isnít broken, donít
fix it.
I hope these suggestions help you understand the physics we will be studying
and perhaps lower the stress level associated with many college courses.
I donít mean for these hints to sound preachy, sorry if they do.
Also, many of these are general studying hints that might be applicable
to other courses. I know this list isnít complete. For example,
I donít mention the all-important topic of time management. If you
have any other suggestions to add to this list, let me know so we can share
them with your classmates!
General Guidance
-
Keep up with the course. Do your
best to not fall behind in reading and/ or homework as new material builds
on previous material. I know this is easier said than done as there
will be some weeks where you will be busy with other class projects and
papers, in addition to non-class activities. I just urge you not
to fool yourself into thinking that you can learn a unitís worth of material
in one night.
-
Avoid marathon study sessions.
Devote a little time each day to studying physics, rather than keeping
your books & notes closed except for one weekly study session.
Also, take brakes while studying. Most of us start to feel mentally
fatigued after nonstop studying.
-
Ask for help when you need it.
Always try to figure out any difficulties on your own first, but when you
are truly stuck, find someone to help you. There is little benefit
from feeling frustrated or lost. Feel free to visit Dr. Jeff, the
physics study room (Seaver 109) where the physics majors often run study
sessions, or work with your friends.
-
Form a study group. Make some
friends in the course and work through the material in small groups.
Donít let these study groups become a crutch- be sure to participate equally
in the discussions. If you need help in locating some classmates
with similar schedules contact Dr. Jeff (or see the course web site) and
heíll try to connect you with others in the class.
-
Do not memorize. Often people
think that memorizing 50 formulas from various example problems in the
text is sufficient. I assure you that this "shortcut" will not help
you in the course. With the combination of problems and conceptual
questions, the exams will test your understanding of physics, not your
ability to memorize. Instead of memorizing formulas, work on understanding
concepts.
-
Rewrite your notes after class.
After class (perhaps also after rereading the text or coming to office
hours), you probably have a better understanding of the material and can
organize it in a clearer fashion. These "second generation" notes
will be much more organized than ones you take in class as you are learning
the concepts.
Reading Recommendations
Reading a science or engineering text is much different than reading a
sociology text or novel. You need to read actively not passively.
The following are ideas on how you can get the most out of the text.
-
Read the assigned reading before coming
to class. If we are going to be discussing Newtonís Second Law,
you should have read that section of the text before coming to class.
You may not completely understand what the text is saying, but this first
pass will help to familiarize you with the concepts and possible applications.
I donít think this is too revolutionary of an idea; after all, if your
English literature class is discussing Romeo & Juliet, you would
be expected to read the play before coming to class so you can participate
in the discussion.
-
Take your time. Science books
tend to be very densely packed with information. If you are only
skimming the text, you will likely miss some of the information.
-
Reread the text several times.
The first time might be to skim for basic vocabulary, but the second (and
perhaps third) should be slower and more thorough. This multi-pass
method of study is usually best for most students.
-
Ask yourself questions. As you
read the text ask yourself "What does that mean?" "When is that concept
applicable?" "Where does that concept stem from?" Using
"how, what, why" type questions can help you better understand the reading.
-
Highlight (or underline) sparingly.
If 99% of the text is highlighted, how will this aid you in locating the
core concepts later? First, read the section without highlighting.
Then return after you have understood the material to highlight (or underline).
If you are marking before you understand, then thereís a chance you arenít
actually highlighting the important parts.
-
Take notes in your book. Donít
simply highlight. Writing the ideas out in your own words can help
you understand them better.
-
Work out the drill problems.
These can serve as checkpoints on your understanding as you read.
Also, before reading the solutions to the examples, try working them out
on your own.
-
Translate equations and concepts into your
own words. Often it is too easy to read an equation without understanding
it.
-
Create your own chapter summaries.
The textís summaries are helpful, but the process of making your own can
be very beneficial to helping you determine what you do and donít understand.
Homework Hints
-
Do not put off the problems. You donít
want to be doing them the night before they are due. While the exercises
usually wonít demand much of your time, the problems tend to be more complicated
(see the syllabus for a fuller discussion of the differences).
-
Donít rush into the problem.
After reading the problem or exercise, set your pencil down for at least
ten seconds and think about what it is asking and plan your solution.
The setting up of a solution is usually the most difficult part of a problem,
so it is worth spending more time thinking about the first few steps.
-
Rewrite your problem solutions.
Just like you wouldnít hand in an essay with crossed out sentences and
illegible words, a problem solution should be just as presentable and legible.
Donít down in scratch work. When solving a problem it is inevitable
that you will make some wrong turns in your solution. Thatís okay;
in fact, it is highly educational. You just donít need to turn in
all of those sidetracks in the final draft.
-
Know your math. Like the syllabus
mentioned, mathematics is the language of physics and engineering.
Knowing the vocabulary and basic syntax of a language will make it much
easier to understand a novel written in that language. Similarly,
knowing algebra, trigonometry, geometry and calculus will make it easier
to understand some of the concepts and problem solutions. (If you
feel as though you need a math review see the textís syllabus or dig out
your old math texts.)
-
Read the feedback given to you.
Exercises and problems offer a mechanism for a teacher to give students
feedback (also the teacher receives feedback from the students).
Look over any corrections or comments on your homework. Also, check
out the posted solutions.
Test Tips
-
Begin studying at the beginning of the
unit. Donít wait until the night before the test to start studying.
-
Focus on the concepts. Understanding
the physical concepts will not only help you on the qualitative questions,
but also the exercises and problems. The first step in solving both
is identifying the principle in action and determining how to express this
concept in mathematics.
-
Relax. I know this is easier
said than done, but it is incredibly helpful. Get some sleep the
night before, donít stress out. The more relaxed you are the less
of chance there is for you do make mistakes on the test.
-
Spend your time wisely. If the
test has five questions, it would probably be a bad idea to spend forty
of your fifty minutes on one of those questions. Not even beginning
some of the problems would be detrimental. A useful time management
technique is to make multiple passes on the test. First, do the questions
that seem transparent to you. Then return to the start and make another
pass to tackle the slightly more difficult ones. If you need to,
make another pass. The idea is that you donít spend too much time
on any one problem.
-
Follow the problem-solving algorithm.
The algorithm is there to not only make your solution easier to understand
for a reader, but also to help you work though a problem. Drawing
pictures, writing down the important concepts and other early steps in
the algorithm might help to jog your memory while you are working.
