Spacecraft software training needs assessment research

The problems were identified, along with their causes and potential solutions, that the management analysts were encountering in performing their jobs. It was concluded that sophisticated training applications would provide the most effective solution to a substantial portion of the analysts' problems. The remainder could be alleviated through the introduction of tools that could help make retrieval of the needed information from the vast and complex information resources feasible

A multimedia information exchange of the industrial heritage of the Lower Lee Valley.

The Lee Valley Industrial Heritage Electronic Archive (LVIHEA) is a model record of industrial buildings composed as a composite of multimedia data files relevant to the interpretation of the region's dynamic industrial environment. The design criteria concerning natural, human and artificial resources are applicable to education and heritage management strategies. The prototype model was evaluated in terms of its efficacy and effectiveness with designated user groups. The developed model will enable qualitative and quantitative analyses concerning the economic, social and industrial history of the region. It can be used as a pedagogic tool for instruction in the principles of structured data design, construction, storage and retrieval, and for techniques of data collection. Furthermore the data sets can be closely analysed and manipulated for interpretative purposes. Chapter one attempts to define the Lee Valley in terms of its geographic, historical, economic and societal context. The aims and resources of the project are outlined and the study is placed in the bibliographic context of similar studies. Thereafter it addresses the processes leading to and a description of the structure of the prototype model. A paper model is presented and the data structures conforming lo or compatible with established planning, archiving and management protocols and strategies are described and evaluated. Chapter two is a detailed description and rationale of the archive's data files and teaching and learning package. It outlines procedures of multimedia data collection and digitisation and provides an evaluative analysis. Chapter three looks at the completed prototype and reviews the soft systems methodology approach to problem analysis used throughout the project. Sections examining the LVIHEA in use and the practical issues of disseminating it follow. The chapter concludes by reviewing the significance of the research and indicates possible directions for further research. The survey is artifact rather than document led and begins with the contemporary landscape before "excavating" to reveal first the recent and then the more distant past. However, many choices for inclusion are necessarily reactive rather than proactive in response to the regular "crises" where conservation is just one consideration in a complex development. Progressive strategies are sometimes sacrificed for the immediate opportunity to record information concerning an artifact under imminent threat of destruction. It is acknowledge that the artefact (building) would usually disappear before its associated documentation and that therefore it was imperative to obtain as much basic detail as possible about as many sites as possible. It is hoped that greater depth can be achieved by tracking down the documentation to its repositories when time permits. Amenity groups had already focussed their attention on many of the more "interesting" sites and every opportunity was taken to incorporate their findings into the LVIHEA. This study provides an insight into the cycle of development and decline of an internationally important industrial landscape. It does so in a structured environment incorporating modem digital technology while providing a framework for continuing study

Improving the accessibility of modelling for management learning : a systems thinking approach using ithink

This thesis describes research aimed at increasing the accessibility of modelling to the general manager as a tool to promote organisational learning and improve managerial performance. An exploratory approach was adopted and a wide-ranging investigation of the whole process of modelling and its relevance to learning was carried out. A review of individual learning, organisational learning and modelling techniques in management, led to the identification of system thinking as a modelling methodology whose role in promoting learning warranted further research. Two major pieces of fieldwork were conducted. Firstly, the process of training managers in systems thinking was studied. Secondly, a case study of the adoption of systems thinking by a large manufacturing company was carried out. During the course of this work, a number of training case studies and a supply chain management training workshop, based upon the use of a generic supply chain model, were developed. This fieldwork identified model conceptualisation as a major area of difficulty for novice modellers. In order to provide assistance in this area, a new framework for model conceptualisation, based upon the use of archetypes and generic models, was developed. During the course of this work an exploration of the relationship between qualitative and quantitative modelling was carried out. This resulted in the development of simulation models of a number of the system archetypes. Additionally, a computerised Delphi-based knowledge acquisition tool was developed. The purpose of this tool was to allow a large group of geographically dispersed people to become directly involved in the modeffing process. In conclusion, this thesis has suggested that there are substantial benefits to be gained from encouraging managers to become modellers. It has also confirmed the potential of systems thinking to support modelling for learning

Paradigms for the design of multimedia learning environments in engineering

The starting point for this research was the belief that interactive multimedia learning environments represent a significant evolution in computer based learning and therefore their design requires a re-examination of the underlying principles of learning and knowledge representation. Current multimedia learning environments (MLEs) can be seen as descendants of the earlier technologies of computer-aided learning (CAL), intelligent tutoring systems (ITS) and videodisc-based learning systems. As such they can benefit from much of the wisdom which emerged from those technologies. However, multimedia can be distinguished from earlier technologies by its much greater facility in bringing to the learner high levels of interaction with and control over still and moving image, animation, sound and graphics. Our intuition tells us that this facility has the potential to create learning environments which are not merely substitutes for "live" teaching, but which are capable of elucidating complex conceptual knowledge in ways which have not previously been possible. If the potential of interactive multimedia for learning is to be properly exploited then it needs to be better understood. MLEs should not just be regarded as a slicker version of CAL, ITS or videodisc but a new technology requiring a reinterpretation of the existing theories of learning and knowledge representation. The work described in this thesis aims to contribute to a better understanding of the ways in which MLEs can aid learning. A knowledge engineering approach was taken to the design of a MLE for civil engineers. This involved analysing in detail the knowledge content of the learning domain in terms of different paradigms of human learning and knowledge representation. From this basis, a design strategy was developed which matched the nature of the domain knowledge to the most appropriate delivery techniques. The Cognitive Apprenticeship Model (CAM) was shown to be able to support the integration and presentation of the different categories of knowledge in a coherent instructional framework. It is concluded that this approach is helpful in enabling designers of multimedia systems both to capture and to present a rich picture of the domain. The focus of the thesis is concentrated on the domain of Civil Engineering and the learning of concepts and design skills within that domain. However, much of it could be extended to other highly visual domains such as mechanical engineering. Many of the points can also be seen to be much more widely relevant to the design of any MLE.Engineering and Physical Sciences Research Counci

Teaching with style: computer aided instruction, personality and design education

The investigation reported in this thesis concerns the possibility of automatically matching the learning styles of design students with appropriate styles of computer aided instruction (CAl). Individual adult learners exhibit preferences for the way information is presented and for the ways in which they are taught. These preferences arise from characteristics known as cognitive styles which are associated with personality. Cognitive dissonance occurs when there is a mismatch between styles of teaching and styles of learning. Under these conditions some students will be discouraged. A survey of students on typical design courses showed them to have particular learning preferences. In this respect they are differentiated from tutors who may prefer to teach in a different style. CAl systems also exhibit styles. These are manifest in features such as the computer's control of learning interactions and the form of information which the system delivers. Computer-based training has often been of a sequential, drill-andpractice kind which encourages rote learning. This style has met with limited success, and it is shown to be unsuitable for most design students. The Myers-Briggs Type Indicator (MBTI) is used to classify the psychological types of design students. Evidence of learning preferences from the MBTI and from related sources is given. From a theoretical description of learning episodes, a computer-based model is developed that provides CAl treatments matched to sixteen learning styles. It is concluded that CAl-based teaching of technological information to design students can be more optimally matched. The principles established have wider implications for communications between designers and others
