Title: Development of a Simple Viscometer
that Utilizes the Steel Ball Dropping Method
Author: Toshikazu YAMAMOTO, Ryoya MAKINO
題目：落球式簡易粘度計の開発
著者：山本利一，牧野亮哉
Abstract
We developed a teaching tool which provides
a simple means for measuring the viscosity
of engine oils. The principle behind this
measuring method is as follows: An oil is
poured into a test tube, a steel ball is
dropped from the top of the test tube into
the oil, the time interval it takes for the
steel ball to drop from the top of the test
tube to the bottom of the test tube is measured.
Based on the time it takes for the ball to
drop, a viscosity rating can be obtained.
There is a relationship between the time
interval and the viscosity of an oil.
This teaching tool utilizes an electromagnet
used to hold the steel ball at the top of
a test tube. A photo-reflector/sensor registers
when the steel ball arrives at the bottom
of the test tube. The signal to the electromagnetic
is controlled with a personal computer. The
signal from the photo-reflector/sensor is
received by the personal computer which then
calculates the length of time it takes for
the steel ball to drop.
In this lesson, Junior high school students
practiced with this teaching tool on fresh,
unused oil, and on oils that had been used
for 5000km, 10000km, 15000km. They compared
their viscosities. We investigated the effects
of this on teaching and learning.
Key words: measuring of viscosity, photo-reflector,
engine oil, teaching tool, measuring by PC

Abstract
This study presents the viewpoint that the
objective of Foundation of Information Science
and Technology is to develop information
technology competency within the Windows
environment. We defined six categories of
educational content for information technology
related to the Windows environment. This
content includes: the programming of object
data which has expanded to multi-media. In
order to teach information technology within
the Windows environment, certain conditions
for the computer language were decided. We
also produced a textbook titled, "Let's
Learn the Fundamentals of Information Technology".
In this textbook multi-media software and
computer controls are covered. We disclosed
the method for making a DLL file which provides
the means for controlling the computer.

Title: Development of a Simple LAN in order
to Teach about Networking
Author: Hiroyoshi TANAKA , Kazuhiro AKANE
題目：ネットワークの仕組みに関する教材としての簡易LANの開発
著者：赤根一浩，田中啓勝
Abstract
We developed a simple LAN (local area network)
as a teaching tool for learning the basic
mechanicsof networking.
Compared to a typical, functional LAN, both
the hardware and software of this basic LAN
are extremely rudimentary. We simplified
the hardware by eliminating a LAN board.
In its place we used the printer interface
which is standard equipment on personal computers.
As a result, we placed more emphasis on the
software charged with managing the system.
We did, however, simplify the management
performed by the software by limiting the
program to all but the most basic elements
that need to be understood. Students learned
the basics of the mechanisams employed in
networking by devising these on their own.
We conducted an experimental lesson using
this simple LAN with University students
who are in the teacher education program.
The overall result showed shows a ligh level
of understanding.
Key words: networking, LAN, Bus format, printer
interface, personal computer,teaching material.

Title: The "Can Crusher", a Practical
Learning Experience in the Metal Working
Class - A Subject Matter Development Project
Author: Minoru TERAISHI, Shigeki ANDOH, Toshinobu

題目：金属加工領域における「缶クラッシャー」の題材開発とその実践
著者：寺石 稔, 安東 茂樹, 浅田 寿展, 杉野 宜孝
Abstract
Even in Technology and Home-making classes
it is necessary to actively pursue environmental
education. By addressing topics which range
from environmental conservation on a global
scale to environmental improvement at each
home, we can make our lives better.
Therefore, we took on the production of the
"Can Crusher" which can be used
in daily life at home. We believed that the
adoption of this subjects matter would result
in the students being more interested in
the environment. We believed students would
take a positive attitude toward environmental
improvement around them, and they would assume
a practical posture towards the effective
use of resources.
The "Can Crusher" has the capacity
to crush even cans made of steel. Because
the product is made of metal, we are able
to teach the students about the effective
use of metal resources. With this theme we
were effective in making the students recognize
the necessity of the waste can collection
movement.
The production process involved in this subject
matter encourages practical learning. The
following topics were covered: 1) preparation
of materials for cutting to a designed size,
layout, drilling, cutting, bending, filing,
painting, assembling and regulating. This
product can be completed in approximately
twenty school hours.
As a result of implementing the above project,
we found that even though some students had
difficulties with the production most of
them were highly motivated and their completed
products were fairly usable. We received
comments from many of their homes that they
want to make use of the "Can Crushers".
Because this device allowed them to throw
away crushed cans they were able to participate
in the waste can collection movement.
Key words : environmental conservation, can
crusher, steel-made cans, waste can collection
movement, encouraging interest in environmental
improvement.

Title: Two Methods of Teaching the Characteristics
of Energies Supplied to Machines
Author: Makoto ARIKAWA
題目：機械を動かすエネルギー形態の特性に関する学習指導法の検討
著者：有川 誠
Abstract
This study was intended to help junior high
school students to achieve a greater understanding
of the concepts and characteristics of energies
supplied to machines. The study compared
two styles of teaching and learning, and
their effectiveness in helping the students
understand the target concepts.
The first method consisted of a series of
lesson plans which included: questions to
present to the students, discussions, lectures,
and the use of audio-visual aids. It was
expected that these activities would enable
students to achieve a greater understanding
of the target concepts than they would if
they were to rely solely on their daily experience
as a base. This method we will call the "active
learning method".
The second method used for teaching was a
conventional lecture method which included
in-depth explanations about the characteristics
of energies, This teaching method included
diagrams of mechanical studies. These classes
were strictly lectures. There was no discussion.,
and no audio-visual aids were used. The two
groups were then compared to see which had
achieved a greater overall understanding
of the target concepts.
The group that was taught using the first
method (active learning method) understood
more of the target concepts than the second
group. Audio-visual aids proved effective
in forming the student's understanding of
the concepts when they were used in conjunction
with lectures, discussions, and questions.
Key words: energies supplied to machines,
conceptual understanding, active learning
method, mechanical studies, audio-visual

Wood Working Instruction
Author: Shin-ichi OKUNO, Katsuhiro MORIYA, Masahiro UEDA
題目：福井県小学校教師の木工作指導に関する調査研究
著者：奥野 信一，盛屋 勝博， 上田 正紘
Abstract
Wood working in the arts and handicrafts course in elementary school is
considered to be a foundation for the junior high school industrial arts
wood working course . Clearly, it occupies a very important position in
a consistent elementary, lower, and upper secondary school technology education
curriculum. What is not clear is how teachers actually teach wood working
in the classroom. Therefore, we sent a questionnaire on wood working instruction
to fourth, fifth and sixth grade teachers who were teaching the arts and
handicrafts courses in Fukui Prefecture. We received 715 valid responses.
The following were concluded from these data:
1) On wood cutting instruction, older/male teachers value skill training
and younger/male and female teachers value safety training.
2) Many teachers instruct students to use sandpaper for part processing,
and to use both nails and glue for joining.
3) Both male and female teachers concluded that regular skill training
is necessary for wood working in the arts and handicrafts course.
4) Younger teachers or female teachers who are not skilled in crafts wish
to have a team teaching system for wood working.
In addition to these conclusions, it was found that it is necessary for
teachers to master the use of some wood working tools and machines.
