Participation:
There is an old saying that "It's
better to be thought a fool than to
open your mouth and remove all doubt."
While this attitude is quite pervasive
among students, it usually constitutes
an impediment to learning in the
classroom.
Class participation is very
important not only for your own success but also for that of your
classmates. So try to become active participants in the learning
community, whether it be the actual
classroom or in the discussion board. Form study
groups, participate in classroom discussions, and be prepared to answer
questions when called upon in class. Of course,
feel free to ask questions at any time. While
attendance is not mandatory, except in
labs and during student presentations, excessive absences
can lower you
participation grade and will also leave a bad
impression.
Homework: To help you keep up with class material, weekly graded (required) assignments have been set up at at http://webassign.net. Expect about 20 problems per week to 10 days, which will translate to about 2-3 problems per day (with proper time management). For best results, you should first work on the problems by yourself with as few resources as possible, as if you were taking a test. That means no notes, no books, no tutor. Remember that frustration and some trial and error are essential parts of the learning process. Merely getting the right answer with the help of the book or a tutor may bypass the critical learning component. Students who rely too much on outside help often develop a false sense of security and experience a collapse on the exams. Of course, you should get help after making a sincere effort and hitting a dead end. However, even after getting help, make sure to reproduce the solution under test-like conditions.
Exams: This is your chance to show off what you
have learned. Much of the material on the exams is taken almost directly
from the homework. So if you do your homework
and stay alert in class, you should have no trouble. The final tends to be
a bit more challenging than the midterms,
particularly for those students who tend
to cram and memorize. On the other hand,
the final can also be your opportunity to make up for any
weaknesses that may have existed up to
that point. Because of the wide spectrum
of preparedness on the part of the
students, the distribution of scores on
the exams can also be quite broad. An
average of 50-60% is not unusual, with
some students significantly above and
some below. If you need special
accommodations, please let me know in advance.
Lab: This is the place where you get a chance to
participate in some "hands-on" activities,
designed not only to make the subject
matter less abstract but are hopefully
also just plain fun.
"In the matter of physics, the first lessons should contain nothing but what is experimental and interesting to see. A pretty experiment is in itself often more valuable than twenty formulae extracted from our minds."--Albert Einstein, A. Moszkowski, Conversations with Einstein, page 67, Horizon Press (1970)
Students will form groups of about 3-5 people and will apply the scientific method to the collection and analysis of data from various experiments related to class topics. For each lab, each group will submit a write-up subject to peer review. We'll try to keep lab as fun and informal as possible, but attendance and punctuality are mandatory.
Webassign
and Canvas:
All assignments in this class are
submitted online either at
www.webassign.net
or in
Canvas (http://Canvas.highline.edu).
Webassign is used
for homework and exams; Canvas is used
for everything else. You
should log in regularly to make sure
that you are aware of all due dates. To
access and submit your assignments, you
need to input your username, password,
and institution name. The institution
name is highline.cc.wa. While webassign
is a powerful instructional tool for
both student and teacher, it is
regrettably not free. Students pay a
per-quarter fee of about $20 online (http://www.webassign.net/info/support/access_codes.html).
Group
presentation: This is your opportunity to
research a topic of interest to you (but
related to course material) in some
depth and educate your peers (the
class), while sharpening your
communication skills. They do say, after
all, that the best way to learn a topic
is to teach it. Your presentation should
include a short poster and/or PowerPoint
presentation. You are encouraged to
choose a topic of particular interest to
you. Keep in mind, however, that it is
ultimately your responsibility to find a
topic. You are also encouraged to use
any other props which you feel will
enhance your presentation and stimulate
your audience. For instance, you may
choose to entertain the class with a
demo (related to the class), which is a
simple experiment that demonstrates an
important scientific principle. A degree
in engineering or astrophysics is not
required, but a creative spirit and an
outpouring of enthusiasm wouldn't hurt. You should work
in groups of 3-5 people, but you must
share the workload.
Journal: A journal is a record of
occurrences, experiences, and reflections
kept on a regular basis--a bit like a
diary. Whether in industry or in an educational
setting, making observations and generally
being more self-reflective are helpful in
identifying areas of strength and weakness
so that appropriate adjustments can be
made and better problem-solving algorithms
can be developed. By directing you to be
more self-reflective, a journal can
increase your effectiveness by helping you
define objectives and set goals, and
monitor progress toward them. Secondarily,
this process would
also allow an outside observer (e.g.,
supervisor or teacher) to offer some
useful feedback. In this class, you will
be expected to keep such a journal and
make regular
entries in Canvas, roughly every
couple of days. Entries
can include things you've learned or are
having trouble with, and any other
school-related experiences that may be
affecting your performance. Here are
some guidelines:
Your first entry should be some comment on the syllabus--basically, to leave the impression that you've looked it over.
Your progress and mastery of the material should be addressed regularly.
You should offer thoughtful critique of the various sections of the textbook.
You should report on your progress with procrastination (a serious issue for most students).
A separate assignment, called 'grade', similar to the journal, will give you the opportunity to argue for the grade that you think you have earned based on the criteria listed in this syllabus. The grade calculator, http://people.highline.edu/iglozman/classes/gradecalc.htm, has a rubric to help you come up with reasonable numbers.
Sample journal entry: "I have been so excited about taking this class, but I'm so frustrated this week because I've been sick with such a bad cold that it's been hard to think and do much of anything. I don't feel like I've gotten as involved in the class yet as I would like to be. I did most of the first homework and really enjoyed it. It was kind of like a learning scavenger hunt."
Evaluations:
In addition to the day-to-day
observations in your journal, you will
have the opportunity to evaluate the
class, the instructor, and your
classmates. Two important areas of
evaluation will be the student
presentations. Evaluation criteria for
the presentation are suggested at:
https://people.highline.edu/iglozman/classes/preseval.htm.
Lab evaluations are described here:
https://people.highline.edu/iglozman/classes/labeval.htm.
The effort that goes into your
evaluations is no less important than
the actual presentation, so please take
it seriously. The exercise of evaluating others
(as well as yourself) is a valuable learning tool
because it forces the evaluator to take
responsibility and focus on important
issues.
Evaluations
will be graded mostly on the effort and
thought that goes into them.
Constructive criticism generally
receives the highest marks. An effective
critique is one which takes a position
and offers a justification. An
ineffective critique is one which offers
an empty statement like "Everybody was
great," with no further justification.
Remember, everyone can always do better,
so try to come up with some tips and
observations. Evaluations should be
submitted in a timely manner in
Canvas. Toward the end of the
course, you will also have the
opportunity to evaluate the course and
estimate the grade that you think you
deserve based on the criteria in this
syllabus. Here's the list of important
opportunities to make observations and
offer analysis:
Forum: One good way to interact with your classmates without the headache of organizing meetings is to exchange ideas in the “virtual forum” or discussion web set up specifically for your class in Canvas. I encourage you to use the forum to solve homework problems together, ask questions, make suggestions, or simply air some thoughts. In addition, important announcements will appear in the forum. Remember that you are all in this adventure together, so please do as much as you can to contribute. Most of you will find visiting the forum a pleasant adventure, a way to hang out with familiar characters. For some, the forum will turn out to be an addiction--but fortunately one of the healthy ones. Note: To get full credit for forum participation, you need to demonstrate not only a consistent effort throughout the quarter but also some depth in at least a few of your posts. As with the science articles (see below), it is not sufficient to unload during the last couple of weeks.
Science articles:
Read an article on a
science-related topic and submit (post)
a short blurb in the
Articles forum. This blurb should be no longer
than a couple of sentences, a quick
summary of the big ideas--just long
enough to whet the reader's appetite.
Include a couple of
challenging questions (and answers)
related to the article, as well as a
reference (link).
Science sources can be found
all over the web, as suggested by (but
not limited to) to this list:
http://people.highline.edu/iglozman/bibliography.htm
Here is a couple of examples::
Read about it here: http://www.space.com/scienceastronomy/planets_quickly_021129.html
Q: How are planets generally believed to be formed? A: After the formation of the core, the young planet begins collects material, 'snowballing' into a larger planet. It is a slow process, and can take millions of years.
Q: What's wrong with that? Sounds good to me! A: Well, beyond Saturn there doesn't seem like there would be enough material to form Neptune and Uranus. Also, it is believed that the only likely way Jupiter could have come into being is through a more rapid formation (this was determined from the composition of Jupiter's atmosphere).
Older article here: http://www.space.com/scienceastronomy/solarsystem/jupiter_elements_991117.html
Q: How is it supposed to work? A: It isn't, people believe stupid things
Q: Has there been any proof? A: No, as a result cancer patients have not been accepting more reliable forms of treatment.
Q: Is there any hope? A: For us or the sharks? There may be a possibility to refine a compound for anti-cancer purposes from shark, but that has yet to be done. As for the sharks...they can only hope we get smarter (for our sake, as well as theirs).

Q: What is beneficial about a robot with pressure sensing abilities? A: Pressure sensing would allow robots to handle more sensitive/fragile objects, and may be one step closer to a human-like robot.
Q: Are there any other possible applications for transistor arrays such as this? A: There are many ways pressure sensing arrays like this can be implemented. Some examples are monitoring hospital patients in their beds with pressure sensing sheets, or possibly a new variety of home security systems.

Q: How often does HST have to be serviced: A: That varies with circumstances (plans, failures, etc.), but every 2-4 years is typical. HST was last serviced in March of 2002 to have one of its cameras replaced. A couple of new cameras were to be installed in 2006, but those plans have now been scrapped.
Q: How long can HST remain in orbit without being serviced? A: Failure of one of its critical components is a random event which could occur at any time between now and a few years from now. The most critical components include gyroscopes (for maintaining direction) and batteries (from 1990, were to be replaced in 2006). Of the six gyroscopes onboard, two have already failed and a third is showing signs of trouble.
Q: Why abandon HST, which has been so hugely successful? A: Maintaining HST is quite expensive and would have involved the development of new technology in the wake of the recent Columbia Shuttle disaster. Its abandonment represents one of many sacrifices science would have to make to help pay for the president's new initiatives. Also, NASA is committed to building the James Webb Space Telescope, considered Hubble's successor and currently scheduled for launch in 2011.
Q: What can be done to extend HST’s life without servicing it? A: As far as preserving battery life as long as possible, HST could run only one science instrument at a time, instead of all of them at once (as it has in the past).
Q: Wouldn’t HST threaten people and property on the ground when its orbit decays and it crashes to Earth? A: To prevent serious injury on the ground, NASA plans to develop a robot which would fly to the telescope, attach a retrorocket, and steer the spacecraft to a harmless reentry over an unpopulated area.
These articles are intended to encourage you to practice your written communication skills, especially as they relate to scientific material. Your effort on the articles will become part of your overall grade on the presentation. While some students find it difficult to add yet another task to their already busy schedules, the potential benefits suggest that it might be a good investment. These include:
Be prepared to respond to questions that might arise in connection to these articles. This is all very informal, so try not to be too stressed about it, but do put some effort into it. As with forum participation (see above), consistency is very important, so try not to unload during the last week or two. You need to do about 1 article per week (in the forum). More is better, less is worse. You also need to respond to at least two articles per week in the forum. Your response not only keeps you alert to others' posts, but also encourages others to keep posting. (An indifferent audience is not very motivating.) Keep track of your activities with regard to articles and comment on them in the journals.
Attitude
and perspective: Although
physics tends to be challenging for
most students, the real difficulty
is not the subject matter but rather
the attitude with which it is
approached. The best approach is to
work hard and apply oneself. In
addition, maintain a positive
attitude and a
love of learning at all times.
Try not whine about how difficult
the material is; instead, try to
have fun and be grateful for your
educational opportunities. When you
start to feel a little stressed from
school, try to think about the
starving orphan in some third-world,
poverty-stricken village who would
love to trade places with you. It's
all a question of
perspective, so try to maintain
a healthy one.
Deadlines and due
dates: Deadlines and due dates are an integral part of the world we live in.
We all have to deal with them and they help us stay on track. In that regard,
this class is no different: All assignments come with a due date. The due date
should not be interpreted as the day to work feverishly on an assignment;
rather, you should be working on assignments with consistency (not in spikes) as
soon as they are available, keeping the due dates in mind as aids in helping you
manage your time and tasks efficiently. Those that have trouble staying on top
of due dates might consider mentally moving the due date up to a somewhat
earlier time. Keep in mind that the ability to keep up with the due dates is part of each
assignment. If you miss an assignment (for any reason), you should explain your
circumstances in your journal and/or in person to your instructor.
***Preparing for class: In this course, students are expected to come to class prepared, having gone over at least some of the relevant material in the textbook. For best results, the class should be considered a supplement rather than a substitute for reading and independent study. The instructor cannot make you learn; the instructor is only the tour guide. So don't be afraid to learn things on your own, outside of class. You are expected to do so--during this class and during the rest of your lives. Throughout the quarter, students will be given frequent opportunities in class to demonstrate their level of preparedness by making a sincere attempt to answer questions posed by other students or by the instructor. While this may seem intimidating at first, it is really an effective way to motivate students to be actively engaged in a classroom discussion. (The alternative, and usually less appealing, option is the dreaded pop quiz. So stay on your toes and don't make me resort to it.:))
Academic maturity: Academic maturity is an umbrella term used to describe those characteristics which allow students to reach their academic potential and achieve growth in an academic environment and ultimately in the field of their choice. Characteristics generally associated with academic maturity include:
In their book Making Sense of College Grades (Jossey-Bass, 1986), Ohmer Milton, Howard R. Pollio, and James A. Eison found that learning-oriented college students were more inclined to explore possibilities and relationships rather than to work only with known facts; they also were more attentive to lectures. In contrast, grade-oriented students who focus on "making the grade"--for example, who only read material that will be tested and view other class reading as an inconvenient waste of time--performed less well on exams, had poorer study habits, and were twice as likely to report having cheated repeatedly. So try to approach your educational opportunities in a mature, knowledge-hungry way. Remember that only about half of your grade will be based on exams. The other half will be based on academic maturity (in its various forms).
Independent learning: In this
class, students are expected to
develop the ability to read the book
and to be independent of the
instructor (as much as possible) in
learning the material. The
instructor should be viewed more as
a tour guide and facilitator than a transferrer of knowledge. For
best results, you should try to
familiarize yourself with the
concepts before seeing them in
class. The due dates for homework
assignments are timed to motivate
you to stay on top of the material
and discourage you from
procrastination.
Critical
thinking: "Critical thinking"
and "thinking outside the box" are
catch phrases which are receiving
increasingly more attention in both
education and in the industrial
world. Traditionally, education of
the masses has emphasized the rote
memorization of facts rather than
depth of understanding. In today's
fast-paced world, however, as
information proliferates and becomes
obsolete more rapidly, the
traditional assembly-line philosophy
of learning can no longer be
considered adequate. Indeed,
information becomes less important
than the ability to access
information, to identify and define
issues or problems, to generate
hypotheses, to construct arguments,
to make inferences, and to evaluate
results. All these new demands
require that students actively
engage in learning rather than
passively "receive" knowledge. So do
your best to become
active learners.
Understanding vs memorization:
Physics deals with quantitative as well
as qualitative concepts. The
quantitative aspects of physics
generally involve the manipulation and
application of formulas. While the
initial impression may be that there are
many, many complicated-looking formulas,
the reality is that all these formulas
are based on only a few fundamental and
relatively simple relations. You will
find that if you invest some time into
understanding these simple relations and
the qualitative concepts behind them,
you will not only gain a deeper and
longer-lasting understanding of physics,
but you will also save yourself from the
daunting task of having to memorize
these formulas and from the recurring
nightmare of misapplying them. For your
continued edification, the "internalize
but do not memorize" mantra will be
chanted repeatedly throughout the
course.
***Computer
literacy: Computers are a
general-purpose tool; they may appeal
to different people in different ways.
One person may like graphics and
animation. Another may like electronic
mail. Another may prefer video games.
Whatever one's particular uses of a
computer, proficiency with a computer
can dramatically increase one's productivity
and potential for success.
Unfortunately, not everyone is
completely comfortable with the use of
computers, and some even suffer from
computer phobia. Fortunately, like all
irrational fears, computer phobia is no
match for a determined, curiosity-driven
mind and gradually dissolves with
practice and perseverance.
As with most new things, there is a learning curve, and feeling some frustration at times is perfectly natural. The important thing to realize is that learning to use computer technology (in its many incarnations) is not something that should be considered a distraction from class work; it IS a big part of the class. Irrespective of background, all students in the class will be expected to master the following list of computer-related skills:
A paradigm shift:
According to William Perry's
Scheme of Intellectual Development,
the typical first-year college
student has a dualistic view of
knowledge, believing that right
answers for everything exist in the
absolute and that the role of the
instructor is to teach them.
Knowledge represents a gradual
accretion of right answers acquired
through effort and obedience to the
instructor. Sadly, traditional
teaching practices, particularly in
introductory courses, tend to
reinforce, rather than challenge,
this unsophisticated view of
learning. Traditional approaches
emphasize the presentation of
information, and define learning as
its absorption. In contrast to this
traditional content-driven paradigm,
an effective student-centered,
learning-oriented classroom involves
a more active approach to learning,
characterized by the following basic
principles:
Active
vs passive: ***In the
traditional model of education, the
instructor is expected to have all
the answers, while the student is
expected to listen, take notes, and
then demonstrate how full of
knowledge he/she has become (usually
on a test). In this model, brains
are essentially treated as passive
receptacles to be filled by the
expertise of the instructor. And while most
educational experts today recognize
that this is not an effective mode
of teaching (as this
learning pyramid illustrates), it is still
unfortunately the predominant mode
of education at the undergraduate
levels. Hopefully, we can do a
little better in this class. In
particular, students in this class
will be expected to be active
participants in the learning
community, teaching themselves as
well as others, being proactive
instead of reactive. While this is
not always most comfortable for many
students, it does appear to be the
best way to learn, which is the
objective in this class.
If you want to build a ship, don't drum up the men to gather wood, divide the work, and give orders. Instead, teach them to yearn for the vast and endless sea.—Antoine de Saint-Exupéry
Here's an interesting pamphlet with some useful tips for and observations about learning physics. For example, it points out that taking good notes in a physics class is quite different from taking good notes in a history class. Do you know the difference? Although written just after World War II, the pamphlet shows that the approach to learning physics has remained essentially the same.
Bloom's
Taxonomy: Much of the philosophy
behind the various class activities
and components is based on
Bloom's Taxonomy of the Cognitive
Domain, a learning theory
based on six levels of intellectual
behaviors: knowledge, comprehension,
application, analysis, synthesis,
and evaluation. These levels
progress from the simplest,
knowledge (the remembering,
either by recognition or recall, of
ideas, materials, and phenomena) to
the most complex, evaluation
(the making of judgments about the
value, for some purpose, of ideas,
works, solutions, methods, material,
etc.).
Learning styles: Have
you ever wondered why you loved history
while your friends hated it, felt
inspired by one particular faculty
member while your friends thought she
was boring? Have you ever been
uncomfortable at a party while others
seem to be having a wonderful time? Do
you ever wonder why others miss
deadlines and never seem to have things
organized? All of these are connected to
our personality type and our preferred
way of doing and viewing things. When we
are in a classroom environment that
matches our learning style, everything
feels right. The teacher is stimulating,
the material exciting, the work
enjoyable. But if the environment does
not match our preferred learning style,
we feel out of place, uncomfortable, and
unable to do our best. There are no
right or wrong, good or bad learning
styles, just preferred styles.
Understanding learning styles and
personality preferences provides an
important dimension of self-discovery
and personal growth for students.
Knowing what we have in common with
others, how we differ, and what is
unique about ourselves can be both
empowering and critical to our success
in college and beyond. One of the most
popular rubrics for understanding
personality types is the Myers-Briggs
Type Indicator (MBTI). What's your MBTI?
Find out here:
http://www.gsu.edu/~dschjb/wwwmbti.html.
Cooperative learning: Extensive educational research indicates that when students learn together in pairs or in small groups, the learning is faster, there is greater retention, and students feel more positive about the learning process. The value of cooperative learning has resulted in its widespread use throughout the country, and it has become a standard part of most pre-service training. Several components of this course, including lab and group presentation, are designed to give you the opportunity to develop some of these skills. When working on group projects, all group members must participate in all aspects of the project, not simply taking turns. While we can all come up with pretty creative excuses why it's difficult to meet as a group outside of class, the ability to do so is an important objective of the class (and in the real world), no less important than the scores on an exam.
