virtual 
graffiti :
 An unfortunate phrase. The Web includes a great 
number of sites devoted to the presentation of artwork, art installations, and 
variety of artistic productions, and whether or not people find them important,
 I think the fact that they can flourish on the Web is terrific. My point, 
 however, was to draw a distinction between the overwhelming 
 number of sites that are used primarily for publicity, and those 
 that are used primarily for purposes other than selling something, or 
 someone. My feeling is that there are actually very few of the latter, and that 
 this is not an inevitable consequence of the nature of the medium. For example, 
 it is discouraging to see how few college and university sites include information 
 rich enough for educational purposes (e.g. local or institutional histories, 
 original documents, or on-line curriculum). At the same time, almost all of these 
 sites do include the cyber-equivalent of an admissions 
 brochure.  (For an important discussion of publicity and images, written well 
 before the birth of the Web, see the final essay in John Berger's Ways of 
 Seeing (Penguin, 1973). For an interesting, if depressing, look at the 
 ubiquity of selling in the U.S., see the recent book by Earl Shorris, A Nation 
 of Salesmen (Norton, 1994)).
 
 
 lab session :
The exact role of the laboratory exercise in secondary and undergraduate 
 science education is open to debate, but I think most 
 scientists and science teachers would agree that the "cookbook" lab 
 session -- one in which the goal is to follow a set of pre-defined 
 procedures, to get the right result -- is neither a particularly productive use of 
 students' time nor an accurate representation of the practice of experimental 
 science. Similarly, it seems that computer "labs" in which results are 
 completely determined by the student-set parameters, no matter how 
 graphically astonishing, do not noticeably improve upon the "cookbook" 
 model; not, at least, if the goal is to give students a feeling for scientific 
 experimentation. Simulations, on the other hand, are nicely 
 handled by computers, but a responsible teacher has to first make clear to 
 students the deep differences between simulation and experiment. 
 
 
 "It all sucks.":
 The lesson here is: Be very careful when you speak to your editor 
 on the phone! This is an accurate quotation, and I agree with it, but it wasn't my 
 intention to have it be a part of this article (note that it does not 
 appear in
 in the version I submitted). The story came 
 up in conversation with my editor at The Sciences, and the only 
 good thing I can claim is that I 
 convinced him not to use the textbook writer's name and affiliation.
 
 From the 
MendelWeb home page:
Not exactly. The links to these various places and sites are scattered 
throughout MendelWeb, and most often come from the secondary source 
material. Thus the glossary and the 
timeline include links to sites 
throughout the world, while the homepage, 
and the html versions of 
Mendel's paper contain only local links.
Friar:
This is incorrect because, by 1851, Mendel was already a priest. According to Iltis 
[1932/1966], on his 25th birthday (July 22, 1847), Mendel was ordained 
subdeacon, on August 4th he was ordained deacon, and on August 6th he was 
ordained a priest.
biographical sketch:
I removed the short biography from MendelWeb, just prior to the first 
edition, because I decided I would rather have students read Orel [1984], 
Iltis [1932/1966], Olby [1985], or even the entry in the Encyclopedia 
Brittanica. I am currently working on a revised sketch that I hope will add 
something new to the worthwhile biographies already available.
textbook:
Consider the following entry for "text-book" from the OED:
1.  
2.  
3.  
4.  
5.  attrib.
 pa
ssing into adj.  Derived from, dependent upon, or typical of a text-book (sense 2); orig. and still occas. in a derogatory sense, implying mechanical adherence to a stereotype; now freq. used in an approbatory sense of an exemplary or classic instance of something.  Cf. copy-book 2 b. 
textbook
narratives:
I describe some the problems of textbook narratives in more detail in
"MendelWeb:
An electronic science/math/history resource for the WWW",
a paper prepared for WWW2 in Chicago. Some of
these problems are captured nicely in these excerpts from the OED's definition of "text-bookish":
eschewing
textbooks and breaking down standard scientific categories:
This is a bit much, I agree, but 
the course did give students a 
sense of learning about science in a much deeper way -- deeper 
technically and philosophically -- than they had previously
experienced in secondary and undergraduate science courses. 
Furthermore, the course allowed students to see connections between 
what applied mathematicians, physicists and 
biologists do, in ways made invisible by traditional departmental 
curricula. Of course, I think most of these achievements were due in 
larger part to the team-teaching and seminar style of the course, than to 
the materials we assigned and distributed.
disc are:
"disc." would have been fine, I think, unless the idea was to make
certain readers wince at the end of the paragraph.
annotated
by readers all over the world:
Althought the collaborative
hypertexts of Mendel's paper have been available and publically
write-able since September 1995, no one has contributed a single
annotation. Although I'm happy that the texts are not being used for
"hello world" sorts of messages, I sincerely hope some of the 
teachers and students who use MendelWeb will soon begin to add their
comments, questions and references to the texts.
virtual
classroom:
The Mendelroom is a virtual space created on a MOO (an object-oriented
multi-user computer program), running on computers in Tel Aviv and in
Washington, D.C. If you are using a computer that can handle a
graphical browser like Netscape, then it is likely that you can use
MendelWeb and the Mendelroom simultaneously. For more information,
take a look at the Mendelroom Information 
Page.
posting their
data:
Although I've yet to find any classes, or teachers, or botany groups
trying to replicate Mendel's experiments, a few friends are determined
to begin growing a few plants in the Spring of 1996, primarily to
provide photographs of the plants for MendelWeb. I am hopeful that a
larger effort can be organized somehow, as I think access to real 
experimental data would be one of the most valuable aspects of
MendelWeb. If you or someone you know is interested in growing peas,
keeping records of the results, and making the data available at/to
MendelWeb, please please let me know (and/or see the data page).
create their own
curriculums:
I discuss this in more detail in my November
10th article about MendelWeb, written for the "In the Loop"
section of Next Wave, the on-line
publication by AAAS and Science magazine.
graded
automatically:
Thanks to some former students who wrote and expressed their disdain
both for multiple-choice questions and multiple-choice questions
dressed up as open-ended questions, I have just about abandoned the
idea of automated homework sets. In the Spring of 1996, I will replace
the first set of problems with new ones, and create a set of worked
problems from the old ones. In the meantime, I will continue to answer
mail from teachers and students about particularly homework problems.
Given world enough and time, of course, I would like to design an 
intelligent database that could respond to short-answer and even 
short-essay questions; and given the restricted semantic domain of 
elementary biology and genetics questions, this doesn't seem 
too unreasonable. If you know anyone who is working on such a project,
I would appreciate your letting me know.
education:
I would go further now, and say that as more (and better) educational
materials become available on the Web, and as more teachers have
access to these materials, teaching may be able to recover/discover its
identity as a craft. If the old model of the classroom
demanded that teachers regularly make severe "practical" compromises
in their course goals and structures, because of budgetary constraints
and/or poor, dated educational media, the new model will demand that 
teachers be clear and precise in the formulation of their pedagogical 
goals, when presented with the enormous supply of new, seductive, and 
often irrelevant, educational media.
will:
Unfortunately, the only way school computers (or any other networked
computers) can be kept from accessing sites that the so-called 
"Communications Decency Act 1996" is meant to eliminate, is to 
only allow school web browsers to visit pre-approved sites; the model 
of simply "blocking out" particular sites doesn't work well when 
"indecent" material is available at sites that appear suddenly, are
short-lived, and later reappear at a different internet address. This may
provide a way to employ great numbers of people in the name of site(s)
supervision, but I think that, at best, it's a deeply flawed way to
side-step an important social issue. As for the Communications Decency
Act of 1996, it seems to me only to preserve and protect the "legal" 
pornography industry in the United States, and I fail to see how 
anyone can be particularly proud of that.
