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.
