title: ‘Getting stuck’ in analogue electronics: Threshold concepts as an explanatory model

authors: Harlow, Ann

subjects: threshold concepts

abstract: Could the challenge of mastering threshold concepts be a potential factor that influences a student's decision to continue in electronics engineering? This was the question that led to a collaborative research project between educational researchers and the Faculty of Engineering in a New Zealand university. This paper deals exclusively with the qualitative data from this project, which was designed to investigate the high attrition rate of students taking introductory electronics in a New Zealand university. The affordances of the various teaching opportunities and the barriers that students perceived are examined in the light of recent international research in the area of threshold concepts and transformational learning. Suggestions are made to help students move forward in their thinking, without compromising the need for maintaining the element of intellectual uncertainty that is crucial for tertiary teaching. The issue of the timing of assessments as a measure of conceptual development or the crossing of thresholds is raised.

title: Development and characterisation of an easily configurable range imaging system

authors: Jongenelen, Adrian P.P.

subjects: range imaging

abstract: Range imaging is becoming a popular tool for many applications, with several commercial variants now available. These systems find numerous real world applications such as interactive gaming and the automotive industry. This paper describes the development of a range imaging system employing the PMD-19 k sensor from PMD technologies. One specific advantage of our system is that it is extremely customisable in terms of modulation patterns to act as a platform for further research into time-of-flight range imaging. Experimental results are presented giving an indication of the precision and accuracy of the system, and how modifying certain operating parameters can improve system performance.

title: The rhetorical organisation of Maori discourse: An illustration

authors: Crombie, Winifred

subjects: Māori medium education

abstract: Almost 20% all Māori students in New Zealand schools are involved in some form of Māori-medium education. These students need to develop competence in using the language for a wide range of purposes. They need, therefore, to understand a range of written discourse conventions. In seeking to assist them in this task, elders and scholars are turning to the works of major Māori figures of the past, works composed when the language was used widely in a range of discourse contexts. However, scholars need ways of analysing these texts and of communicating their findings to others. The primary aim of this paper is to demonstrate one such approach. A single letter of condolence written in Māori is analysed here in terms of rhetorical discourse structure. On the basis of the analysis, a number of hypotheses concerning epistolary discourse in Māori are put forward. The primary hypothesis is that letters of condolence written in Māori by highly competent users of the language are likely to be characterized by an overall Problem-Solution rhetorical prototype involving spiral multilayering.
