Take a look at <A HREF="heath.html"> my son Heath</A>.

<P>I'm a &quot;Senior Lecturer with Security of Employment Emeritus,&quot;
which means that they paid me to teach full-time (not to do research), but was
essentially tenured, even though I'm not supposed to call it that.
(But since nobody outside the University of California has any idea what
that title means, I'm allowed to call myself a "Teaching Professor Emeritus"
instead.  Research faculty at some other UC campuses don't allow this for
their teaching faculty, because they're
afraid people might think we're like them and they'll get cooties.)
I am retired as of July 1, 2013.  But I'm continuing to work on various
education-related projects at the University.

<P>I taught many of the lower division (freshman and sophomore)
<A HREF="http://www.eecs.berkeley.edu/Courses/">computer science courses</A>
at Berkeley, as well as one called <A HREF="195-syllabus">Social
Implications of Computing</A> and
occasionally others.I'm (still) faculty advisor of the
<A HREF="http://www.csua.berkeley.edu/">Computer Science
Undergraduate Association</A> and of the
<A HREF="http://www.ocf.berkeley.edu/">Open Computing Facility</A>.

based on the amazing
<A HREF="http://mitpress.mit.edu/sites/default/files/sicp/full-text/book/book.html">textbook</A>
of the same name, still, after 50 years, the best computer science
book in the world.  My lecture notes, sample exams, and other course documents
are preserved <a href="61a-pages">here</a>.  The videos are archived off campus
because they're not captioned and the campus is required to caption any videos
they present to the world.  I am pleased and honored that people are still
discovering my course online and pursuing it with interest, even without
gold stars for completing it.

<P>I'm also interested in the use of computers in
pre-college education; I used to be a <A HREF="lsrhs.html">high school</A>
teacher, and was involved in the development of the Logo programming
language.  More recently I've been helping develop the Snap<i>!</i> language
(see below).
<!-- And since 2004 I've been volunteering in a local elementary school. -->

support an undergraduate-level
introductory computer science course.  We have
<A HREF="http://inst.eecs.berkeley.edu/~cs10">established such a course</A>
at Berkeley, and are working on spreading it to other colleges and high
schools through teacher preparation and support efforts.

<P>This project really excites me &mdash; sneaking the ideas of Scheme
into the visual metaphor of Scratch!<br />(<img src="ring.png"> at
the right is &lambda;.)<br />
Recently we also snuck in the vector and matrix functions of APL. :)

<P>I'm also interested in the use of computers in
pre-college education; I used to be a <A HREF="lsrhs.html">high school</A>
teacher, and was involved in the development of the Logo programming
language.  More recently I've been helping develop the Snap<i>!</i> language
(see below).
<!-- And since 2004 I've been volunteering in a local elementary school. -->

a/k/a <A HREF="http://snap.berkeley.edu">BYOB</A>) is an extended version of
<A HREF="http://scratch.mit.edu">Scratch</A>, a
drag-and-drop programming language for kids from MIT.
I've been working on it with Jens M&ouml;nig, adding
<A HREF="BYOB.pdf">higher order functions</A> and true object
inheritance for first-class sprites, to
support an undergraduate-level
introductory computer science course.  We have
<A HREF="http://inst.eecs.berkeley.edu/~cs10">established such a course</A>
at Berkeley, and are working on spreading it to other colleges and high
schools through teacher preparation and support efforts.

<P>This project really excites me &mdash; sneaking the ideas of Scheme
into the visual metaphor of Scratch!<br />(<img src="ring.png"> at
the right is &lambda;.)<br />
Recently we also snuck in the vector and matrix functions of APL. :)
