TEACHING PROGRAMMES BY Omer ROUCOUX
_____________________________________
This directory contains 5 programmes to help students to learn reading
measurements on various apparatus. They are described below in order
of difficulty. The first few can be used in lower schools, the last
ones at GCSE level. At the end of these exercises, the student is
invited to type his name. If a printer is connected, the name, the
score and the time taken to do the exercise, will be printed. Full
explanations are given at the beginning of the exercises. (No printer
driver is necessary)
!Thermo is a tutorial, it offers various thermometer scales divided
as follows :
* one graduation for each degree, numbered every 10 degrees.
* one graduation for every 5 degrees, numbered every 10 degrees.
* one graduation for every 0.1 degree, each degree numbered.
* one graduation for every 0.2 degrees, each degree numbered.
* one graduation for every 0.5 degrees, each degree numbered.
Three exercises of each are offered in the above order, that is 15
exercises in total.
The scales of the last three come in a random range.
The temperatures are random in all scales.
!ThermoRND is an exercise which can be used for testing.
The various scales described above are offered mixed.
Ten exercises are offered.
!Burette . Exercise to learn to read a burette, the graduation
increases downwards. The student is asked to read the top level,
then the second level, then calculate the volume delivered. The
scale range varies at random from 0 to 50 ml. The result is
recorded after 5 exercises.
!Watts. Can be used to teach or test the ability of the student
to 1. read a simple voltmeter (0 to 20V) integers only.
2. read two different scales on an ammeter :
a. 0 to 5 A, graduation by 0.2 A.
b. 0 to 1 A, graduation by 0.04 A (difficult)
3. Multiply V x A to find the power in Watts.
The use of a calculator is advisable. Name, score and time taken
are printed after 5 exercises.
After 3 mistakes the programme is interrupted and the student is
advised to consult his teacher.
!Oscilloscope. Reading an oscilloscope screen.
The divisions are set : Y : 1 volt per division,
X : 0.005 sec per division.
The questions are : Is it AC or DC ?
Voltage ? (peak to peak in AC).
Period ? ie. the duration of a full cycle.
The frequency is then calculated, to 3 decimals, by the computer.
A variety of DC, and AC of different periods and voltages are
offered.
After 3 mistakes the correct reading is given and the student
advised to consult his teacher.
Note :
1. These programmes have been first written for the BBC B machines
and the BBC Master, the !RUN Basic files should still work perfectly
on these computers.
2. It has been experienced that when the students make mistakes they
tend to press ESCAPE to exit and start again. It could be useful to
disable the ESCAPE key by introducing, in one of the first lines of
the listing, the command *FX 229,1 (obtain the listing by dragging
the !RUN file onto the !Edit icon placed on the icon bar, introduce
the change, then Save by pressing F3)
3. In this revised version the titles, which were at first written in
MODE 7, are now in MODE 1. Many modern computers do not use MODE 7
any more.
These programmes are Public Domain and free. I would appreciate any
constructive criticism and to be told if they are used in a class
situation.
