EDUCATIONAL
SOFTWARES
All software require DOS to run and are available on both 5.25"
and 3.5" disks. Price per copy is P 150.00 for 5.25" disk
and P 175.00 for 3.5" disk.
Chemistry
STRONG AND WEAK ACIDS
Type : Tutorial
The software consists
of two short programs. The first program, SWACID simulates the ionization
of strong and weak acids in solutions. This graphic simulation is
designed to aid in the teaching of chemical equilibrium in acid solutions.
The other program, STRWKA, graphically simulates how different weak
acids ionize to different extents.
Elementary Mathematics
FACTOR GAME
Type: Game
The game is a reinforcement
of the lessons on factors of a number and prime factors. The lesson
aims to stimulate thought and expression on these topics and to sharpen
skills in determining all factors of a number.
SNAKES AND LADDERS
Type: Game
This is like the typical
Snakes and Ladders game board. The difference is that the snakes and
ladders are hidden and that the child has to remember where they are
hidden. The game aims to improve the user's memory.
Environmental Science
SALT WATER INTRUSION
Type: Simulation
This is the initial version
of the software about saltwater intrusion. It is a simulation of the
saltwater intrusion in the Philippine Archipelago. Data were provided
by Mr. Ceferino de la Cruz, a Senior Hydrologist of the Local Water
Utilities Administration, Balara, Quezon City.
WATER POLLUTION
Type: Simulation
This program simulates
a simplified model of water pollution focused on the reduction of
dissolved oxygen resulting from the breakdown of wastes in a body
of water. POLUT allows students to investigate the effects of five
factors (type of body of water, temperature, type of waste, rate of
dumping, and type of treatment) on a water body's ability to hold
waste and maintain fish life.
High School Mathematics
LINEAR FUNCTIONS
Type: Graphing tool
This program graphs equation
of the line of the form Y = AX + B. Serving as a tool in graphing
linear functions, it can be used to investigate the concepts of slope
and y-intercept.
LINEAR INEQUALITIES
Type: Graphing tool
This program is a tool
in graphing linear inequalities. Solutions to linear inequalities
can be taught using this software as a tool.
PRODUCT OF TWO BINOMIALS
Type: Drill
The program provides
visual thinking about binomial multiplication with the use of squares
and strips. The product of two binomials is viewed as the area of
the rectangle formed by the strips and squares. One of the factors
(binomial) is taken as the width and the other (binomial) as the length.
See also complementary video lesson.
STRETCHING AND SHRINKING OF SINE AND COSINE CURVES
Type: Graphing tool
This is a program that
offers practice in graphing functions in the form of Y = Asin(Kx)
and Y = Acos(Kx). The students can concentrate on how the change in
the values of the amplitude and frequency can affect the graph and
how these two are related to the coefficients of the function.
TOWER OF HANOI
Type: Game
This program is a computerized
rendition of the Tower of Hanoi, a game which became popular in Europe
at the end of the nineteenth century. The game was allegedly originally
played by priests in the Temple of Brahma using three diamond needles
on which rested 64 golden disks, the largest one at the bottom and
the smallest at the top, forming a tower.
The object of the game
is to move the tower of disks from the left needle to the right needle
under the condition that only one disk may be moved at a time and
at no stage may a larger disk rest on top of a smaller disk.
In the program, a player
may start with a left tower of up to 10 disks.
