An analysis of knowledge representation of students in electronic problem tasks

This paper investigates the nature of learning outcomes of thirty six electronics students who were receiving training under the recent reform processes advocated by the Australian government. The reform processes place great emphasis on macro issues thereby unintentionally relegating the micro issues, such as learning in the classroom, to a lower priority. Such misdirected emphasis may hinder the development of an intelligent workforce. A multi method approach which involved a problem task, interviews and concept maps was used to establish the learning outcomes. The learning outcomes were analysed to identify the nature of students’ knowledge structures and the sophistication in their understanding of the topic “Frequency Division Multiplexing”. Students’ knowledge structures and levels of understanding were compared with those generated by 3 experts. The findings indicated a low level of understanding and a very lean knowledge structure with limited relational links to other elements in the given information. Furthermore, a comparison of students’ knowledge structures and levels of understanding was made between students with more than 2 years work experience and those coming to their course straight from secondary schools. The findings of this analysis did not support the argument that work experience enriches students’ knowledge and understanding, as students with no work experience performed better then the work experience students. Thus, there needs to be more empirical research on the nature of real work experience routines and how it affects learning rather than theorising on ideal work situations.
