        We have the entire series mentioned. For the most part we are
quite satisfied with it. P. Hewitt is entertaining and informative. The
tapes appear to have been made when he was teaching an introductory service
course at the university level. I don't have a current price list here at
home but will look for one on Monday.
        Other observations : We would have prefered that they be shorter
15 minute segments and at a somewhat more advanced level.( It depends on
what you intend on using them for. We use them a lot for our lower level
physics course but only sparingly for the regular course.) He hold the
attention of all groups well but as is the case with anything you can
over due it and his "jokes" which are funny in video 1 & 2 loose a bit by
the time they view video 15.
        I believe that they are elementary enough so that they could easily
be used in 9th grade Physical science courses - if you have such a beast.
        I hope this helps. I will post more information

PS I forgot to mention that most of them are a full class period long (45
minutes) and are his actual lectures. I show only parts of each in my regular
course because of the large time commitment required to show the whole tape
and the rather slow pace he sets.
