Course content
(see Blackboard for weekly updates)
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 discussion web. Form study
groups, participate in classroom discussions, and be prepared to answer
questions in the discussion board. Of course,
feel free to ask questions at any time.

Homework:
To help you keep up with class material,
weekly graded (required) assignments
have been set up in Blackboard. For best
results, you should start working on the
homework as soon as it becomes available
and you should make an effort to be as
independent as possible, referring to
the book or other resources when necessary.
Keep in mind that
the real learning is in the journey.
Merely getting the right answer with the
help of a friend or tutor may bypass the
critical learning component. Of
course, you should get help after making
a sincere effort and hitting a dead end.
Blackboard:
All assignments in this class are
submitted online in
Blackboard (http://blackboard.highline.edu). Email should
never be used to submit assignments. You
should log in regularly to participate
and to make sure that you are aware of
all due dates. For help with Blackboard:

****Midterms and Final:
Exams are your chance to show off what you
have learned. If you do your homework
and stay alert in class, you shouldn't have too much trouble. 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 in a
science class, with
some students significantly above and
some below. If you need special
accommodations, please let me know in advance.

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 it, 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.
Your should report on your progress with procrastination (a serious issue for most students).
Your final entry should include an overall impression of the course and the grade that you think you have earned based on the criteria listed in this syllabus.
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."

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 BlackBoard. 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.

Group
presentation: (Does not apply to online
astronomy.) 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 presentation.
You are encouraged to choose a topic of
particular interest to you; some ideas can be
found here:
http://www.flightline.highline.edu/iglozman/classes/project_ideas.htm. 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.
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.
Science articles: Read an article on any science-related topic (doesn't have to be astronomy) and submit (post) a quick blurb in the Articles forum. This blurb should be a just long enough to whet the reader's appetite but not longer than a couple of sentences. Include a reference and a couple of challenging questions (and answers) related to the article. These articles are intended to encourage you to practice your written communication skills, especially as they relate to scientific material. 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:
Science sources can be found all over the web, as suggested by (but not limited to) to this list:
http://flightline.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.
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 one article 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.
Stargazing: Because this is an astronomy class, students will be expected to become familiar with the night sky. This is not only a requirement, but is also quite fun. At least twice per week, you will need to post in the Stargazing forum (in Blackboard) observations you have made of the evening sky. A telescope is helpful, but not required. As with the science articles, the objective is not only to learn, but also to teach. Here's a typical observation:
At the moment, the sky is cooperating. So put on your mittens get the hot chocolate ready and run outside for a quick peek. Betelgeuse (in Orion), Aldebaran (Taurus), and Mars form a nice triangle. In the neighborhood of Aldebaran, you should spot a little cluster of stars called Pleiades. It looks like a tiny Dipper. With binoculars or better, you should make out 7 or more bright stars. It's a very famous cluster, quite pretty, and is also the Subaru logo. Of course, if you see some other sky critters, feel free to share.

resources helpful:
Teaching/grading philosophy: Most teachers
want students to focus on learning and not
be too preoccupied with points. To promote
this mindset, the grading scheme in this
class rewards you more for being motivated
and well-rounded than for achieving perfect or near-perfect scores on exams. In
particular, perfect scores on all exams but
with very little contribution to the
learning community may yield no more than a
grade of B. On the other hand, a student who
gets decent, though not necessarily stellar,
scores on exams (e.g., 75%) but is
always asking questions, working with and
helping others, demonstrating a thirst for
knowledge and growth, trying to do more than
required (e.g., bringing interesting
science news to the attention of the
class, asking provocative questions, and basically trying to learn
and understand) will definitely be in
contention for an A. The highest grades will
be reserved for those people who not
only score decent on exams, but also
demonstrate a respectable work ethic
and make a contribution to our
learning community. My motivation for using
this "nontraditional" grading scheme is to
encourage students to become independent and
self-motivated learners, so that learning and growth
continues well after the class is over.
You'll find that if you can learn to be
internally driven, rather than driven by
some arbitrary point system, you'll end up a
lot more successful and will probably have a better
quality of life. So whenever you don't get
the grade that you want on a homework
assignment or an exam, think of
it as an opportunity to learn from your
mistakes rather than as something that will
prevent you from transferring to some
competitive graduate or undergraduate
program.
Attitude
and perspective: Although science tends to be challenging for most
nonscience 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. Since procrastination is by far the most common excuse for missed
assignments, assignments will usually NOT be accepted after the due date.
Keep in mind that the ability to keep up with the due dates is an important
aspect of each
assignment. If you miss an assignment (for any reason), you should explain your
circumstances in your journal and participate more in the forum to minimize
the penalty.
***
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 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 vs stupid pet tricks: "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 and try not to
react in a Pavlovian manner
to a few dangling points.
Understanding vs memorization:
Astronomy, like any other branch of
science, deals with quantitative as
well as qualitative concepts. The
quantitative aspects of astronomy
generally involve the categorization
of a seemingly vast amount of
information into a few relatively
simple principles. You will
find that if you invest some time into
understanding these principles and
the qualitative concepts behind them,
you will not only gain a deeper and
longer-lasting understanding of
astronomy and the scientific method,
but you will also avoid the all too
common and painful mistake of trying to memorize
a gazillion factoids. 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.
According to constructivism, a
popular theme in contemporary
theories of education, learners do
not acquire knowledge passively but
construct it actively based on their
experiences. But while most
educational experts today recognize
that this is not an effective mode
of teaching, it is still
unfortunately the predominant mode
of education at the undergraduate
levels. Hopefully, we can do a
little better 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
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?

Cooperative
learning: A learning community is a group of people all connected by a
common educational or developmental goal. 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 curricula.
One common technique in traditional class settings is for a teacher/facilitator
to assign people into groups, which then engage in some classroom activity and
report their results to the greater learning community. The activity may be the
discussion of some hot topic, a lab, a PowerPoint presentation, etc. Many
e-learning environments replicate this sort of activity and framework, utilizing
environments like Blackboard to
manage and facilitate the students' interactions. 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 or how
the discussion board takes too much time, the
ability to collaborate is an important objective of the class (and in the real world),
no less important than the scores on an exam. So, for the benefit of all, please
contribute to the learning community.
