- ItemThe evaluation of computer based training as a method of teaching map reading in a military context(Stellenbosch : Stellenbosch University, 2002-03) Conradie, Anje; Cilliers-Hartslief, M.; Theron, C. C.; Stellenbosch University. Faculty of Arts and Social Sciences. Dept. of Psychology.ENGLISH ABSTRACT: Map reading forms an integral part of every soldier's training. Although all troops are exposed to map reading during basic training, they thereafter do not frequently work with maps on a daily basis, but are still required to apply this knowledge during field exercises or combat situations. Various forms of training are available. Computer Based Training (CBT) is a technique that may contribute to the improved acquisition and retention of knowledge when the subject matter requires of students to visualise concepts, as CBT engages multiple senses. CBT incorporates principles from the Component Display Theory and Constructivism, which suggest that CBT might result in superior map reading competencies when used as an alternative to conventional, classroom based, map reading instruction. .The objective of this study was firstly to determine whether CBT, compared to conventional classroom instruction, enhances the acquisition of knowledge when teaching users how to read a two-dimensional (2D) map. In addition, the study had as its objective to determine whether CBT leads to improved retention of 2D map reading knowledge over a one month period when compared to conventional instruction. Finally the study aimed to determine the factors that influence learning when using CBT as the training medium. A basic randomised, between subjects research design, was used to test the hypotheses that eBT would result in the improved acquisition and retention of 2D map reading competencies. The control group consisted of 30 students and the experimental CBT group of 29 students. All subjects were personnel from the School of Armour of the South African National Defence Force. With regards to map training, the majority of the students had exposure to Geography up to grade 12 or further training. A new training programmewas designed. The programmewas developed in two equivalent formats, one appropriate for conventional classroom instruction (control group), and a eBT format for the experimental group. Each student received two manuals. One was a self-study manual that had to be completed before commencing with the course, and the other was received on the first day of the course. Both the trainers also received a manual that contained all the correct answers to the map reading problems forming part of the programme. The eBT programme was designed on paper with the help of a template for the storyboard. A lesson was designed for each day of the course, but students could review any lesson previously studied. Before the students started with lesson 1, they had to complete a test on the computer to determine the extent to which they have acquired the information in the self-study manual. After passing the test the students could select lesson 1. A mind-map was designed for each lesson to help students orientate themselves. For both groups the information studied was placed in the context of "Operation Night Owl", an interactive practical mission. The eBT group had the computer as a guide, providing textured maps and possible answers. Three tests were used to evaluate the students and to gather data regarding their performance. The students were not informed about these tests as the researcher wanted to measure natural acquisition and retention, and not the amount of time that they had studied. Analysis of variance (ANOVA) indicated that the two groups did not differ statistically significantly (p>,05) in their initial degree of map reading knowledge. The average test percentage increased from the pre-test to the first post-test (knowledge acquisition), indicating that the class group increased by 15,2 % and the eBT group by 19 %. Hypothesis 1 states that eBT in comparison to traditional instruction enhances the acquisition of map reading knowledge when teaching users how to read a 2D map. The difference between the class and eBT means for post-test 1 (knowledge acquisition) was, however, statistically insignificant (p>,05). A comparison of the means of the post-test 2 (retention) results of the class and eBT groups clearly indicates that the performance levels retained one month after training, also do not differ statistically significantly (p>,05). The study therefore also fails to corroborate the hypothesis that eBT would result in the greater retention of map reading knowledge when compared to conventional classroom instruction. Based on the results found when eBT results were compared with the traditional classroom technique, it may be advisable to combine classroom teaching with eBT. During the completion of the mission segment of the course, students tended to form natural groups to complete the questions. As working together may result in better understanding of new information (peers learn from each other), it is therefore recommended that the eBT map-reading course be combined with more discussion groups. In conclusion, the results do not suggest that eBT is a superior training technique for the teaching of map reading competencies. Numerous literature sources however do indicate that eBT can contribute significantly to the learning experience, making it still plausible that eBT could indeed, upon further refinement of the programme, contribute to teaching of map reading competencies.
- ItemAn investigation into the usability of asynchronous information techology for a virtual E-learning information sharing environment at a university in South-Africa(Stellenbosch : Stellenbosch University, 2003-03) Scholtz, Karin; Cilliers-Hartslief, M.; Stellenbosch University. Faculty of Economic and Management Sciences. Department of Industrial Psychology.ENGLISH ABSTRACT: Institutions for tertiary education are now more than ever realising the advantages of supplying the growing population with more effective and flexible learning environments through the integration of technology based media. Educational institutions are faced with the challenge of embracing technological changes within the educational domain in order to maintain their competitive position within a global arena. The University of Stellenbosch, as many other tertiary educational institutions, are challenged to view them as being part of an integrated knowledge society responsible for the reproduction of knowledge as a national and global commodity. The recent acceptance of an explicit strategy concerning educational processes and the creation of an Electronic Campus ensured that the University of Stellenbosch would maintain their strategic position through the development and improvement of the quality of the central education, research and community service functions within the university. The purpose of the research conducted within the boundaries of the University of Stellenbosch were to enhance and improve the quality of the learning and information sharing processes between various role players through the exploration of available communication media and the examination of relevant concepts. The specific objectives of the study comprise the following: ■ Objective One: Through the use of alternative subjective and objective test methods, including observation and the use of a questionnaire to conduct an empirical study to evaluate the usability of the various asynchronous computer based communication media, with specific focus on course management systems, and video streaming; ■ Objective Two: Make recommendations based on the findings of the study to potential users of the alternative media and applications in terms of the limitations and benefits; ■ Objective Three: To use the findings, together with an examination of the user needs and applicable concepts, to make recommendations to assist in future decisions regarding the value of the integration of these media into the creation of a high value interactive virtual learning environment; ■ Objective Four: Given the findings, to make recommendations for future research. Empirical tests were conducted in order to examine the usability of WebCT and Microsoft Producer as it was anticipated that the degree to which the communication media adds value and enhances the education and information sharing process will be influenced by the usability of the specified media and the role players' perceived need for the specific media. Empirical test were descriptive in nature and included survey research methods and usability laboratory tests In summary, the data obtained shows that the sample population holds favourable attitudes with regard to the usability of both Microsoft Producer and WebCT. WebCT and Microsoft Producer holds the potential for enhancing and improving the quality of the learning and information sharing processes between role-players within the University of Stellenbosch by providing a useful, reliable, easy to use, consistent, compatible, learnable and likeable system. The integration of WebCT and Microsoft Producer in the context of the University of Stellenbosch will enable role-players to complete their educational and research activities with accuracy in a timely competent and economical fashion.
- ItemAn investigation into the usability of synchronous information technology for a virtual e-learning and information sharing environment at a university in South Africa(Stellenbosch : Stellenbosch University, 2003-04) Ekermans, Gina; Cilliers-Hartslief, M.; Stellenbosch University. Faculty of Economic and Management Sciences. Dept. of Industrial Psychology.ENGLISH ABSTRACT: As the information age evolves, society is undergoing changes based on developments in technology that have tremendous implications for the educational systems. Institutions of tertiary education are increasingly facing the pressures of globalisation. Associated with this is the knowledge society that demands experience with technology, different skills and a different learning experience (US, 2001). Furthermore, new information and communication technologies have demonstrated the potential to transform the way that knowledge is packaged, delivered, accessed and acquired, thereby altering higher educations' core production and delivery processes. Institutions of tertiary education that want to remain competitive, both locally and internationally, should, therefore, act proactively to facilitate the successful and innovative integration of relevant technologies into currently established practice and procedures. The University of Stellenbosch (US) recognises the importance of staying abreast with these global and local changes. The Virtual Information Space (VIS) project for optimal information sharing is a research initiative that developed as a direct response to the need for an inquiry into the functionality of alternative synchronous and asynchronous computer-mediated communication media (CMC), to be provided as part of the technological infrastructure of the US for enhanced information sharing and communication. The VIS project provides the framework within which this study was conducted. The aim of this study was to conduct an exploratory study through the use of empirical research and prototyping, by quantification of the usability of synchronous CMC media, for application in the South-African on and off-campus tertiary education environment (focused at post graduate level), in order to enhance information sharing between inter alia, information service suppliers, lecturers, students and researchers at the US. It was anticipated, however, that the degree to which the synchronous CMC media add value to the learning and information sharing processes within the VIS, will be influenced by the usability of the software applications within which the media are embedded, the perceived need of the role-players for the media, as well as the feasibility and viability of the systems when employed within the technological infrastructure of the US. These elements were, therefore, empirically investigated by conducting several usability experiments in a setting which simulated a usability laboratory, in order to acquire the necessary subjective and objective data, related to the identified goals and objectives that encapsulate the aim of this study. In order to demonstrate the value of the VIS environment, a theoretical perspective is provided by means of a literature review of the fundamental concepts of communities of practice and flexible learning. It is proposed that the use of the synchronous CMC media (embedded within the software applications) will assist in the creation of a VIS that supports the more advanced educational paradigm of constructivism by linking users into collaborative conversational networks, thus forming learning communities (better known as communities of practice) in cyberspace. The purpose of these communities is to create a means through which ideas and materials can be shared and exchanged, aiding individuals in building their own conceptual networks of interrelated ideas, strategies and theories and therefore construct and share knowledge. Information was obtained concerning participants' characteristics, preferences, needs and evaluation of the usability of the two software applications, NetMeeting and Yahoo Messenger, when utilised within the technological infrastructure of the US for the purpose of increased information sharing and communication. Performance measurement data (related to selected usability criteria) was obtained during the experimental phase, as well as information about the feasibility and viability of the systems when utilised within the technological parameters of the US. The analysis of the information consisted of descriptive statistics as the research aimed to illustrate the attitudes concerning usability, the perceived needs for the software applications, as well as the feasibility and viability of the systems. The results revealed that both NetMeeting and Yahoo Messenger were perceived by the participants as usable, achieving a positive rating on almost all of the dimensions of usability it was tested on. In the case on NetMeeting, technological limitations imposed on the system (such as bandwidth and network traffic) severely limited the effectiveness of the system as a whole and require further investigation to ensure successful implementation. Technological limitations in the case of Yahoo Messenger mainly centered on the unstable server environment that the system functions within. Hence, further research is therefore needed to ensure successful implementation and utilisation of NetMeeting and Yahoo Messenger within the technological parameters faced by the US.
- Item'n Ondersoek na die verband tussen die Groot Vyf-persoonlikheidsfaktore en opleidingsprestasie by volwasse basiese opvoeding en opleiding leerders(Stellenbosch : Stellenbosch University, 2003-03) Dercksen, Sarita; Cilliers-Hartslief, M.; De Bruin, K.; Stellenbosch University. Faculty of Arts and Social Sciences. Dept. of Psychology.ENGLISH ABSTRACT: The aim of this study was to investigate the nature of the relationship between the Big Five personality factors and practical and theoretical training performance in adult Basic education and training (ABET). The existing literature on the subject was surveyed; this is followed by a report on the results of the empirical investigation. The experimental group consisted of 82 learners who followed an ABET level-4 course. Personality was determined by means of the Five-Factor Non-Verbal Personality Questionnaire (FF-NPQ), while cognitive skills were measured with Raven's Standard Progressive Matrix. By using the Pearson product moment correlation coefficient, multiple regression analysis and factor analysis, it was established that, apart from IQ, there was a significant positive correlation between agreeableness and practical training performance. Although there was also a significant, but small, positive correlation between neuroticism and practical training performance, the influence of the former factor on practical training performance could not be confirmed by a regression analysis. Only IQ and to a lesser extent neuroticism, conscientiousness and extroversion showed a relation with theoretical training performance. Once again, the influence of the latter three factors on theoretical training performance could not be confirmed by a regression analysis. The conclusion is thus drawn in this study that only IQ has a significant influence on theoretical training performance. Results also indicate that characteristics such as trust, helpful behaviour and co-operative behaviour, which indicate agreeableness, help to promote receptiveness in training in practical work, especially with respect to skills training. It appears that the role of personality factors with respect to training performance depends on: a) the nature of the training programme being followed, b) the degree of difficulty of the training programme, and c) the work or task objectives for which the training is being undertaken. The conclusion was drawn that the findings of studies on the relationship between training performance and personality should be interpreted with circumspection and that a great deal of research is required in this area.
- ItemA training needs analysis into map use in a military context(Stellenbosch : Stellenbosch University, 2002-03) Philander, Elisca S.; Cilliers-Hartslief, M.; Stellenbosch University. Faculty of Arts and Social Sciences. Dept. of Psychology.ENGLISH ABSTRACT: The primary objective of the South African National Defence force is the protection of its citizens against external threats. The nature of the work, especially in operational situations, very often causes members of the SANDF to work in remote and unknown territory. The SANDF is composed of different units such as the army, air force and navy. All of these units typically control a specific aspect of the environment, especially in operational situations, and is very often also geographically spread over a large area. The battle commander would typically be in charge of all these units and must direct and control them efficiently towards achieving their assigned mission. In order to be an effective battle commander, the commander must thus be able to understand the terrain that his/her units are operating in, and maps are often the only information to base such understanding on. Map use is thus a critical success factor in effective battle command, and also for every member of the units navigating the often unknown terrain. The aim of the study is to conduct an investigation into the status quo of map use proficiency in the military, and specifically the South African National Army. The investigation comprises the following: • To conducting a detailed task analysis into map use in a military context, in order to establish specific map use functions and related skills regarded as critical in the military context. • The development of a proficiency test, taking the form of a questionnaire, based on the skills identified in the task analysis. Comparing the results of the questionnaire with map use skills identified in the task analysis, to determine the level of map use proficiency in military context. The secondary aims of the study comprise the following: • To investigate the level of map use training and determine if a need exists in term of additional map use training in the military, based on subjective opinions. • To investigate the level of computer literacy and the need for formal computer training in the military context. The key conclusions of the study are the following: • A gap between optimal and actual performance has been identified in terms of map use in the military context. • This gap can largely be attributed to insufficient structures and processes within the military context to facilitate effective map use.
- ItemUsability within the digital battlefield : usability issues as applied to the digitised battlefield within a Southern African military context(Stellenbosch : Stellenbosch University, 2002-03) De Jager, Madia (Madia Martie); Cilliers-Hartslief, M.; Stellenbosch University. Faculty of Economic and Management Sciences. Dept. of Industrial Psychology.ENGLISH ABSTRACT: Defence forces around the world are experiencing a period of dynamic change with new force structures being combined with new technologies in an effort to enhance effectiveness. Present day resources and technology available to the modern society, have facilitated the evolution of warfare as a technologically advanced enterprise, with the decided emphasis on the digitisation of the battlefield. With rapid development in the field of battlefield digitisation there is an increasing need to address the important issues and challenges facing the military. In order to meet strategic defence guidelines, it is necessary to integrate the capabilities of defence forces with modern technology. In this regard the South African Defence Force is striving towards the digitisation of the battlefield. This digitisation can potentially satisfy the many requirements set for the Defence Force, in a more timely and cost-effective manner than traditional methods of functioning and training would be able to achieve. Effective situational awareness and command and control structures are essential for any military operation, especially with increasingly complex military demands. Key areas of importance are the collection, dissemination and management of information, which if executed skilfully, will result in forces capable of operating more effectively and with greater flexibility. Decision makers on the battlefield continually suffer from information overload due to the extremely rapid inflow of information. This is likely to worsen with the continued introduction of new information technologies. The technology level of any defence force should therefore be appropriate, driven by usefulness and cost-effectiveness. The digitised battlefield allows for the execution of near realistic military exercises, while conserving material and reducing the detrimental impact on environment and personnel, as is the case with traditional exercises. A key issue of focus is the usability and integration of related technologies within the digital battlefield. Promoting optimal usability through continuous and comprehensive user-based evaluation is crucial and will result in increased human performance through interaction with technology. Optimal usability must be engineered into any product (defined as something produced by means of either human or mechanical work) from the inception of the product's life cycle. Within today's technology orientated society, the digitisation of the battlefield and the usability thereof have become increasingly important issues. Most research has investigated the concepts of battlefield digitisation and usability in isolation, and little co-ordinated effort has been made to integrate digitisation and usability, even though the relation is important and necessary. A study of this nature has not hitherto been conducted within the South African military context. The purpose of this study is to provide a theoretical background of the issues of military digitisation and usability, in order to determine the significance of this relation. This research aims specifically to promote the viewpoint that usability is central to military digitisation, as well as to emphasise the importance of user-centred approaches to system development and utilization. The result will be enhanced human performance and satisfaction when interacting with digital battlefield applications. The theoretical perspective is provided by way of a literature review of the relevant military and usability concepts. Military functioning is discussed, highlighting the importance of situational awareness and effective command and control capabilities. The digitisation in the military is examined with specific reference to Virtual Reality and simulation. An overview of usability (within a human-computer interaction and user-centred design context) and usability evaluation methods are provided. This research was conducted during a military exercise conducted by the South African National Defence Force. A usability inquiry approach was followed with questionnaires distributed to participants involved with the Command and Control Digital Battlefield System. Information was obtained concerning participants' characteristics, likes, dislikes, needs, and understanding of the digital battlefield system. The analyses of the information consisted of descriptive statistics as the research aimed to illustrate the attitudes concerning usability and the digital battlefield. The results provide an understanding of the perceptions of the users regarding the digital battlefield system and its usability. Conclusions are drawn from results obtained and recommendations are made for future research.
