The program requires 7MB of free hard disk space and it is
distributed compressed in three floppy disks (1,44 MB)
accompanied by a specially developed installation program and
a 10 page manual. The manual gives answers to all possible
problems that may appear when installing the program (e.g.
fonts, sound driver etc.).
The operations provided by ToolBook, are expected to
contribute to the integration of a hypermedia application,
suitable for teaching and random knowledge searching
(browsing). Each interactive page, which has already been
constructed, can easily be transferred. Thus by determining
the suitable set of nodes and links, a hypermedia application
may easily be developed.
5. ASSESSMENT AND FUTURE OUTLOOK
The contribution of the application to the learning process can
be summarised in the following points:
. Reduction of the time and increase of the
effectiveness of teaching, via the audio-visual
means that are used (sound, dynamic images,
animation, graphics)
° Structural learning since the user cannot go on to the
next section without proving to have absorbed the
concepts presented in the present one.
. Availability and repeatability of training and teaching
at all desirable times for the student.
° Reduction of teaching cost. The cost is reduced to
that of integration and production of the application.
. Increase of motives for learning the particular
subject. The response of the system to the student
actions increases and stimulates his/her interest.
. Quick and easy access to information and transfer of
teaching the process outside of the classroom. The
application simulates instrument functions, which
would be time consuming if presented to the whole
group of students.
e Entertainment provision through the educational
process, utilizing the interactive capabilities and takes
advantage of their instant response.
Moreover, using "Photogrammetrist v.1.0" several problems
such as the large amount of students, the lack of equipment
and the way in which the students are examined, can be
confronted. The integration of such applications is ideal for
classes with more than 30 students since they considerably
reduce the relevant cost (Stubkjaer, 1994).
It is considered as highly important that the package may be
used as a self teaching tool, as a tool for supporting practical
work and as a supplement to conventional teaching.
In the future it is planned to put the package to the test of the
3rd year students, who come in contact with Photogrammetry
for the first time in the course of their studies at the
Department of Rural and Surveying Engineering of NTUA. The
feedback from the students, in form of an appropriate
questionnaire, will be analysed in order to modify and adapt the
package to their practical needs and requirements.
Finally the evolution of authoring tools and the great
improvement of CD-I, CD-V, the vast spread of CD-ROM's,
Photo-CD, Multisession CD's and the significant progress in
networking, assure a brilliant future for similar applications of
Computer Assisted Learning.
