Abstract

Learning/Teaching methods, in the field of Science-based technological subjects, have been developed during the research. These methods emphasize the "Functional Analysis of Technological Systems". The analysis includes identifying structural components of the system, the Processes implemented by them and the scientific principals on which these Processes are based.  

The goals of this research are to examine the effect of the approach of "Functional Analysis of Technological Systems" on the pupil's success in learning unfamiliar technological systems, in the following domains:

A.    Achievements in understanding of the system structure, it's operation principles, troubleshooting and intelligent use of it.

B.     Pupil's attitudes towards technology.

A learning/teaching model of technological systems has been developed in this research. The model emphasizes "Functional Analysis" approach in learning/teaching unfamiliar technological systems.

In order to implement the suggested model, a learning unit - "Functional Analysis of Technological Systems" - has been developed. The unit focuses on studying the functionality of  the technological systems.

The main findings indicate that the achievements of pupils in the treatment group, regarding the question which refers to understanding and troubleshooting characteristics,  were higher on the post-test than the achievements of the pupils in the control group.  The difference between the averages was significant. In addition, there was a significant improvement in pupils' attitude with regard to "Technology " among the girls in the treatment group and the boys and girls in the control group.

The implications of the research findings, in the theoretical aspect, on the learning processes is that it is advisable to increase the number of examples in the beginning of teaching technological systems and  shift gradually to more intensive functional analysis afterwards.  

Relating to practical aspects the implication is that including the "Functional Block Diagram" of a system as integral part of the "user's manual" may contribute to a better understanding of the system, which might lead to more effective utilization of the potential usefulness of the system.

The contribution of the research might also be expressed in creating a theoretical basis in order to cope with unfamiliar technological systems in the following aspects:

A.    Study implementation possibilities of abstract technological learning/teaching subjects.

B.     Getting familiar with potential possibilities that identify and use similar elements needed in transfer of learning situations.

In the practicable aspect, the significance of this research is to develop and validate research tools for studying theoretical factors relevant to teaching/learning unfamiliar technological subjects.
