Subject:    dissection

This topic has been probable hashed over here before...but I'm a relatively
new user of this forum and would like to get a feel for what is happening
out there in the real world.  I know this is NOT a scientific survey, but
I'm willing to collect data for a few weeks and then repost the results
sometime before school starts in the fall (for some of us!).

What are your personal feelings about the use of dissection in middle and
high school classes.  And what (if any) is your school's position on the
topic?

If your school has a position statement/paper on the topic, could you also
please include a few lines about this (I'll also summarize these).

And finally, If you have read a good article lately - tell about it (and
I'll create a bib of these).

Well, I hope I haven't created a monster (or maybe I do?).

thanks for your time

    I was wondering if others throughout the world have noticed a whitish
    haze around the sun, supposedly due to the eruptions of Mt. Pinatuba.
    The weather around here lately is much cooler than usual which the
    climatologists say is due to the eruption and a significant blocking
    of the sun's rays by the haze.

  I don't know doesn't material there in 30 kms shield anything.
  But Mt Pinatubo throw a great amoung ash and sulphur axid (<-
  is this correct word?) up to 20-30 kms layer.  These material
  have formed many interesting optical effect in atmosphere,
  such as strong dawns and dusks, thin wavy clouds into horizon
  (ash clouds), afterglows, Bishop's ring etc.

  Bishop's ring is a diffraction phenomenon due to small ash
  particles

 Easy way?  You can buy a Litmustik(tm) tester PHH-1X for $44 from Omega
Tech.-- about the size of ~3 pens taped together, it can test from 0 to
14 points with 0.1pH resolution (+/- 0.2pH accuracy) and an operating
temp of 0 to 50 celcius.

 Expensive way?  Listing at $395, the PHH-20 series is a pocket-sized
reader with 0.001pH accuracy, automatic or manual temp compensation, and
single or dual point calibration.  It will also determine the correct
temperature characteristics of the electrode and buffer solutions.
Additionalfeatures include hold finction and chart recorder output.

  Well, exactly I haven't noticed any differenze, but perhaps
  the summer is warmer than usual.  I am not sure, if it is
  very easy to explain temperature changes so easily.  You 
  need look up statistics from longer periods and maybe wait
  few years.  I don't the climate there, but here in Finland
  could eg summers be very different in diffrenet years.

Hi David--
I'm a new user of k12 and was doing some looking around in bulletin 
boards.  Came across your questions about Optical Data's Laserdiscs.
I too have only previewed these...but my school in Midlothian, 
Virginia has purchased the set of discs from AAPT called Physics 
Classics...or something like that.  It has a lot!! of the old PSSC 
film loops on disc, plus a few other things.  Have not used them in 
the classroom yet, but will be using them this year.  Seems to be 
veryworthwhile.  Since this is such a late reply...maybe you've 
already made some decisions or heard of things already.  Would be 
interested in what you decide to go with....have been working on 
spending some grant $$ in the same direction.
Good luck

    Hi Paul,

 PW>   I wish we could see the sun long enough to tell.  After two years of
 PW>   drought, Ohio has had a stationary front hanging over it for the
 PW>   entire month of July, resulting in nearly a foot of precip.  Local
 PW>   rumors point to a recurrence of El Nino.  Is there perhaps a
 PW>   relationship to Pinatuba as well?

    From what the climatologists are saying, it would appear so. Actually,
    they also said El Nino is fading, not recurring.  Here, we have had
    very wet and cool days.  It feels positively like October more than
    July.  In fact, what is really mystifying (and depressing) is that
    the trees are starting to turn yellow already.  This normally doesn't
    happen until the middle of September around these parts.  The
    climatologists were saying that we can experience an entire summer
    of cool, wet weather, followed by an abnormally cold winter.  Their
    reasons for this were that El Nino was fading, Mt. Pinatuba has
    envelopped the earth with a shield of pollutants at a height of
    30 kilometres which will last from 7 to 10 years, and sun spot
    activity is fading after peaking in 1989.  Weather tends to be warmer
    when sun spot activity is higher.  All in all, San Diego is beginning
    to look pretty attractive as a winter hang-out.  :-)

    I asked some friends in Ottawa last week-end if things were weird
    there.  They too are having lots of rain, cool temperatures, and
    leaves are yellowing there as well.

    Now I'm curious to know what the Mt Pinatuba "shield" (Bishop's ring,
    according to our friend in Helsinki) does to the sun's rays that
    the trees would be confused.

Hi Carol,
Chris Rowan and I visted with Dr. Ball today out at UTEP.  From what
Dr. Ball told us, the MathMagic project is right on target because it
encourages students to verbalize mathematical concepts.  He vigorously
expressed his support for developmental mathematics and the use of
language to create and "solve" problems.  He indicated that the
university math program has done a literal 180 degree turn around in
its approach over the last several years.  They are moving away from
the symbolic approach toward a language based approach for freshman
students.  Dr. Ball also expressed concern over the district's plan
to do away with all remedial math programs.  He said this could have
the ultimate effect of "watering-down" the regular math courses over
time.  I guess time will tell.

An earlier posting explained *MathMagic as a cross district effort to 
have elementary, middle and high school students involved in a project 
of using telecommunications to solve word problems. The response has 
been very encouraging, so we are posting part II- *MathMagic Goals:
                        *MathMagic Goals
        
1)      To increase students' cognitive abilities (emphasizing 
strategies) 
        by challenging them to solve open-ended problems.
        
2)      To emphasize the importance of addressing problems in a clear, 
        concise and logical manner.
        
3)      To increase students' abilities to work cooperatively within 
their
        class and within the global telecommunications environment.
        
4)      To familiarize students with computers and modems as tools for
        problem solving projects.
        
5)      To provide a means to overcome distance and culture barriers by
        encouraging students to share their thoughts across the city, 
the
        state, the country and even the world.
        
6)      To allow students an opportunity to associate math with 
real-world
        applications.
        
7)      To increase student motivation for math problem-solving and in 
        doing so, increase students' scores on standardized tests.
        
8)      To provide students with opportunities for developing skills in
        written expression.

Organization: FidoNet node 1:161/470 - IISME-NET, Berkeley CA

Bob:

I came upon Sheila's reply to your message about Calculus teaching
techniques.  I have been teaching Calculus for about ten years now and
while I still don't have everything down pat, I have learned a few things!

I pretty quickly discovered that even though the students in Calculus
classes are obviously very bright and good math students, they need to be
"persuaded" (inspired, encouraged, bullied, ...) into doing their
assignments with care so that they are communicating logical thought
processes.

At the beginning of the year, I whizz through the review to get their math
brains up to speed and then really slow down for their introduction to
limits.  I call the limit part of the course  "the brick wall" because it
seems to be the hardest concept for them to grasp all year.  In order to
differentiate between "where are we headed? and "where are we going to
be?", I do things like running at the door, asking them to predict the
outcome.  There are of course several possible outcomes, none of which can
be predicted by observing the way I approach the door- I can open the door
and pass through, I can veer off, I can stop or I can crash into it (they
love that one!).  Then I drum into them that

lim  f(x) tells us nothing about f(a).
x->a 

Once they have the concepts of limits solidly absorbed (mixed metaphor? if
it's absorbed it can't be a solid?), they usually don't have a lot of
trouble understanding the concept of the slope of the tangent to a curve
being the limit of the slope of a secant to the curve and we are off into
the mechanics of differentiation.

A lot of my students are taking, or have taken, Physics and there are all
kinds of applications of both differentiation and integration in Physics
and Econ.

In the classic area-between-two-curves and volume-of-a-solid-of-revolution
problems, I insist that the draw in the "representative rectangle" on their
diagrams.  It not only prevents errors but also keeps them in touch with
the basic concept of integration as a limit-of-a-sum process.

After the AP test was over this last year, I had my students split into
teams of three and each team was responsible for teaching the class a
section of Sequences and Series.  Half their grade for this part of the
course came from a test at the end (each group supplied three questions on
their section of which I selected one) and the other half from peer
evaluation.  I felt that it worked very well and it was a very good
experience for those who had never formally taught before (I wanted to say
formerly formally but there is enough echo in this echo already!)

I hope that these are the kinds of things that you were interested in
discussing.

It is more than likely that the wreck is still covered with sand  since that area of the lake is like that.  I am a teacher in Burlington Ontario Canada near Toronto but I am a native of Sault Ste Marie not too far from Escanaba and I am a novice shipwreak buff.  Let me know if you are successfull in your search.
