both sides OF an equation.
ON Saturday q problem was solved,
the solution Of which was recommended
| as a model for other problems.
The first step was a logical state
ment resulting in the equations, then
the solution proper, and lastly the
proof.
II was shown that the proper way ~
teach the "Blnomlal Theorem" Is to
lead up to 1t lnductively. The method
OF having pupils memorize the formula
and then make the application. was
criticized as unsound F'ormulne for
evolution were derived and applied in
the solution of problems.
The interest manifested in the work
of this department Is genuine ana
abiding,
Prof Hornbeak, in the department Of
science, has discussed methods in phys
iology, physics and chemistry this
week.
The work in physiology has consisted
of methods OF teaching the circulatory
system, the respiratory system and the
eye. 1t was suggested that the clrcula-
tory system be taught Immediately
after digestion, and that the teacher
should begin with absorption. thus
showing how the digested food gets
into the circulation and becomes a
part OF the body The heart, arteries
and veins Of beef We're dissected In
the presence OF the class This work
was done In such manner as to show
the arrangement OF the muscular fbers
Of both auricles and ventrlcles. the
valves of the heart, their arrangement,
attachments and structure. The arter-
les and veins were carefully dissected
and their structure observed In the
next lesson the lungs We're dissected be-
fore the class and their anatomy
exhibited. An interesting feature of
the lesson was the initiation of the
lungs. Air was forced into them by
means Of the condensng syringe; when
filled they presented the general APP
pearance of the lungs I'm the living ami
NAL. In this condition a dissection
was made revealing their cellular struc-
ture.
II was suggested that in the study OF
circulation and respiration It would be
interesting and instructive to place q
dog under the influence of chloioform
make an iucision in his side and OBJ
serve the action OF the heart and lungs
Wednesday afternoon the teachers
were taught how to dissect the eve
In such manner as to show the optic
nerve, the coats, humors, lens, iris
etc. This ended the work IN physl-
olosy. Teachers presenting the sub
tect In the manner outlined In these
lessons cannot fail to incite their pu-
pills to vigorous mental effort and in
spire them with desire to know more
about these God-given temples, our
bodies
In physics methods of presenting the
following subjects have been discussed;
The siphon and principles involved, 81
phon fountains and now to make them.
The instructor showed In this lesson
how the teachers could lead their pu-
pills to construct much OF this appar-
otus out Of bottles and glass tubes.
Some interesting principles were made
manifest by means OF the experiments
In this lesson.
On Wednesday the subject of specific
gravity was presented eNperlmentally.
The members of the class performed
number OF experiments, by which they
were led to discover for themselves the
principles involved. Having arrived at
the principles, they were required to
solve a number of problems In which
the principles We're applied. This les
son was intended as a model lesson on
the subject. The lesson Thursday was
devoted to the subject OF falling bod
les" The formulate We're arrived at by
experimental data obtained from the
Atwoods machine. The process was Of
course inductive. Having established
the formulae. the pupils should be re-
quired not only to solve problems by
use of them but should also make or
iginal problems involving the various
principles, on Friday the subject of
heat was presented to the class.
Many OF the text books We're criticized
adversely for presenting the subject
unnaturally. They present theories be-
fore the data on which the theories are
based. Data should be first obtained
by experiment. We should learn all
the facts We can, and with these facts
before US fabri ,ate n theory that will
explain them. 'Heat is made OF mole
cular motion" was emphasized and
many facts explained by 1t. Latent
heat was shown TO be no heat at all
but molecular potential energy. The
nature OF specific heat was also dis
cussed and a method of teaching 1t
suggested Other books came for criti-
Cism on account OF not presenting the
subject Of radiation OF heat clearly.
All bodies that have any molecular
motion give some Of this motion out
to surrounding bod 49, whether the sur
rounding bodies have less or more mo-
ton. In other words, IA man leaning
up against nm iceberg receives heat
from the iceberg, but at the same time
gives more heat to the Ice than he re-
ceives from 1t. Hence his Temperature
is lowered. This fact was illustrated by
simple experiment.
Next week In the department of sci
ence two lessons will be given I'm LIGHT
and three in electricity. Also Ave les
sons in methods of teaching chemistry.
Mrs. 70. o. Evans. who has charge
OF the department OF musia, has dis
cussed not only methods, but has ac-
tu1lly taught the subject matter.
This study Is new 10 many. and will
this year appear for the first time
among the list Of subjects required
for the certificates given by the school
of methods.
During the course Of instruction no,
only have model classes been present
to Illustrate the work but the teach
