The title of the study is integrating road traffic safety education in the teaching and learning of science and technology. The overall goal of this study was to develop a tool for the integration of Traffic Safety Education (TSE) in the teaching and learning of Science and Technology in School. As such, four research questions (stated in 1.2.1 to 1.2.5) were raised on critical aspects of the problem so as to direct the course of the study to provide solutions to the problem. These research questions were formulated into the aims of the study as stated in section 1.3. To attain these aims, a literature study and interviews were conducted. Through interviews and a literature study, it was found (among other things) that: • TSE has great potential for the reduction of road accidents/ collisions, and its teaching in school will prepare our learners to be safe road users. • Science and Technology has tremendous impact on traffic safety, and the three have much in common, which does provide room for them to be integrated in school curricula. • School educators are not adequately equipped to integrate TSE in the different learning areas. Consequently, an integration model called "Multilateral learning area integration model" has been developed for the integration of TSE in the learning areas of natural science and technology (see 7.2 and 7.3for details). Eleven recommendations were made in section 8.4 on the basis of the conclusions (in section 8.3) drawn from the proceedings of interviews and the literature study. These recommendations if implemented accurately, would undoubtedly contribute to solving the problem investigated in the study. This study has therefore made a valuable contribution to laying a solid foundation for Combating the problem of high road accidents/collisions on South African roads. / Thesis (Ph.D. (Education))--North-West University, Potchefstroom Campus, 2005.

Doctor of Philosophy / Department of Human Nutrition / Valentina M. Remig / Preventing foodborne illness and promoting safe food practices among all age groups is a high priority, particularly for college students because little about their food safety awareness and food handling practices has been reported. The research aim was to evaluate food safety attitudes, beliefs, knowledge, and self-reported practices of current upper-division college students, and to determine whether a three-module interactive educational intervention, developed for this study, positively influenced these variables. Comparisons between health and non-health majors were made. Two methods of data collection were used with volunteer health and non-health majors: focused food safety discussion groups during academic year 2004-05, and a pre-experimental design. Prior to engaging in either method, students completed an on-line food safety questionnaire (FSQ), adapted from a telephone survey used at K-State with older adults. The FSQ was administered again to those in the pre-experimental design group one week after exposure to the food safety educational intervention. Five weeks later, the FSQ was administered to determine whether changes in attitudes, beliefs, knowledge, and self-reported practices persisted over time. Focused food safety discussion group responses were qualitatively evaluated. Pre-experimental statistical analyses included Wilcoxin Signed Rank, Friedman, Mann-Whitney U, Chi Square tests, and Spearman rho. Focused discussion group findings indicated that students perceived themselves at low risk for foodborne illness; few used food thermometers; students without health backgrounds mimicked undesirable home practices; and students stated being open to changing non-recommended behaviors. Pre-experimental findings showed the effects of intervention were improved food safety attitudes, beliefs, and knowledge, with the strongest effects seen in health majors. Students' FSQ attitude scores increased from 114 to 122 (P<0.001), FSQ belief scores increased from 86 to 98 (P<0.001), and FSQ knowledge scores increased from 11 to 13 (P<0.001). Intervention resulted in some improved food safety self-reported practices for health majors but not non-health majors. Intervention module post-test scores improved significantly for all students; health majors had greater increases. Conclusions. Focused food safety discussion groups were useful for obtaining food safety information from college students; educational intervention improved college students’ food safety attitudes, beliefs, and knowledge and for health majors, some self-reported practices improved.

This is a case study of a rural school in the Moloto area. The objective of the enquiry is to explore the responses of children to road safety input that they receive at school. Children’s experiences as road users were gathered through intensive interviews with them, their parents and teachers and corroborated by my observation of children using the Moloto road and other arterial roads in the village. The study was informed by the interpretivist paradigm. Road safety education is part of the mainstream curriculum in South African schools but the environment for delivering it effectively is counterproductive in a school that lacks resource materials and trained teachers. The little that is taking place, as the study shows, is class-based, lacks context and focuses on teaching pedestrian skills with no practical input. The community’s unsafe road use behaviour of walking in the middle of the road and crossing the road everywhere undermines whatever road safety skills children might have learnt at home or at school. Key findings of the study are: children’s development of pedestrian skills; children’s constructions of road safety knowledge and their value of life and road signs; the negative influence of the unsafe “road environment”; and children’s attitude to road safety. Although children theoretically know what to do when using the road, in practice they do not show safe road use behaviour. Their construction of road safety knowledge is mainly informed by the practices of the broad community. This paradox between what the literature prescribes, what the national curriculum entails and what the children apply in their everyday use of the roads is the main finding of the study. Although children are enthusiastic about road safety education the same cannot be said about the teachers who are demoralised and not sure whether what they are doing is right or wrong. However, the children understand the value of life and the danger of using the road infrastructure recklessly even though their road use behaviour suggests otherwise. The low level of formal education among parents and the lack of support for teachers from road safety officers do not help the situation. Effective road safety education delivery depends on a number of variables or factors. Where these conditions are not available, the whole process becomes a futile exercise. In conclusion, road safety education can be summarised as a process with sequenced goals: The provision of information about injury risks and how to avoid them, changing attitudes towards risk and safety, and altering behaviour. Training should include the development of clearly defined pedestrian skills through guidance by a more skilled individual and practice in the road environment. Education can thus underpin both legislative and environmental measures by creating a climate of opinion that enhances a culture of safety which is not evident in the Moloto community. It will take political will and resource allocation for road safety education for any meaningful impact to be made in delivering road safety education and pedestrian skills effectively in a rural school like the Moloto primary school in Mpumalanga. / Thesis (PhD)--University of Pretoria, 2010. / Early Childhood Education / unrestricted

Background: The aim of this study was to investigate the use and management of hazardous chemical substances (HCS) at a chemistry department in a selected Higher Education Institution in Gauteng province. Method: A quantitative, baseline descriptive study was conducted using a structured survey checklist. The population consisted of the chemistry department. Other than purposive observation by the researcher, employees present during data collection were approached for further clarifying comment to survey questions. Results: It emerged that physical-, health- and environmental hazard classes of HCS were present; and that hazard types included flammable liquids, HCS with acute toxicity and carcinogenicity. Selected exposure control measures were lacking which created risks of fire and explosion. Conclusion: The study reflected the use and management of HCS, the actual and potential human exposure and the exposure control measures. Varying degrees of compliance were found, which, if attended to, should mitigate risks to health and safety. / Health Studies / M.A. (Nursing Science)

The call to better prepare nurses in safety and quality performance resulted from the concern of the Institute of Medicine regarding egregious gaps and errors in U.S. hospitals that resulted in serious injuries and patient deaths. Quality and safety education for nursing (QSEN) competencies were set forth in 2005 to enhance nursing curricula and nursing students' preparation for practice; however, QSEN's integration and implementation have been gradual and inconsistent. This qualitative interpretive study was guided by Senge's principles of the learning organization and Benner's professional development model. Using face-to-face interviews, the perspectives of 9 full-time nursing faculty members at 2 private nursing colleges in the Northeast United States were obtained about QSEN integration into their curriculum. Data analysis employed the use of open in vivo coding, categorizing, and the formation of themes. The results indicated that QSEN integration was perceived as complex and daunting due to faculty's limited knowledge about QSEN, lack of adequate preparation to develop and employ instructional strategies, lack of adequate time to teach, and limited learning opportunities at clinical sites to develop competencies such as teamwork and collaboration and informatics. Meaningful reform in nursing education may occur as leaders engage faculty members in meaningful dialogue to better understand the complexity and challenges of QSEN integration, including faculty members' needs for successful implementation. Nursing students may then be better trained to understand the nature and consequences of human and system errors and appreciate higher standards of care that will result in a decrease in preventable injuries, medication errors, and patient deaths.

This applied dissertation was designed to provide a better understanding of the effectiveness of out-of-class safety net corrective instructional activity practices conducted beyond regular classroom instruction for lower secondary level (9th- and 10th- grade high school) students within mastery learning educational environments. The study was designed to shed light on the impact and implications of these practices on Bloom’s vanishing point (Bloom, 1971) and Arlin’s leveling effect (Arlin & Westbury, 1976). Seven mastery learning structured international schools in geographic proximity, of similar size, and utilizing the same program of study were used in this study. Three of the schools that employed a safety net program were the basis of this study, and the four schools that did not have in place a safety net program were used as a control for this observational research. Normed Measures of Academic Progress (MAP) RIT scores (Northwest Evaluation Association, 2005), grade point averages, and safety net program data were used in a series of case-control tests to determine the effectiveness of out-of-class corrective instructional activity safety net programs for above-average and below-average achieving students. The mean study and control group RIT percentile ranking scores for the students was nearly 1 standard deviation above the averages reported by the Northwest Evaluation Association (2005), so these relative comparisons involved bright students. This large volume of data enabled analysis of the effects of out-of-class safety net activities on school-wide and individual improvement in literature, writing, mathematics, and comprehensive results. Series of conclusive nonparametric analysis were used instead of normal distribution tests because of the out-of-bounds skewed nature of the data. Analysis of the data suggested that safety netting programs benefit all students, irrespective of whether or not students received out-of-class corrective instructional activities. The MAP RIT scores of below- average achieving students were not affected by attending a school with a safety net program but their GPA results improved in all subjects. Arlin’s leveling effect (Arlin & Westbury, 1976) most likely accounted for improvement of MAP RIT scores for above- average students who attended a school with a safety net program but their GPA results were not affected. These contrasting benefits masked the school-wide test results, which suggested that a school district might not realize an overall increase in MAP RIT and GPA results when adopting a safety net program. Students identified in need of safety netting services benefited by having been placed in the program up to twice in any respective course, but a point of diminishing returns was reached when a student fell 3 or more units behind in a course in relation to the progress of the class.

The mining industry in South Africa contributes significantly to the national economy. Despite stringent safety legislation, mining accidents cause numerous fatalities and injuries. Inadequate or insufficient training is often cited as a root cause of accidents. Conventional class-based safety training has not reduced the incidence of accidents significantly. By contrast, virtual reality training tools can provide simulated exposure to real-world working conditions without the associated risks. This study describes the application of design-based research (DBR) in the design and development of two desktop virtual reality (VR) systems for safety training in the South African mining industry. The results of a usability context analysis were applied in the design of a VR prototype on generic hazards recognition and rectification, which was used and evaluated at South Africa‘s largest platinum mine site. A case study was conducted to investigate the causes and occurrences of falls of ground, which resulted in the design and development of a second VR prototype focusing on identifying and addressing underground geological conditions. DBR was also used in the generation of an evaluation framework for evaluating VR training systems, namely the Desktop VR Evaluation Framework (DEVREF), which is the major deliverable of the research. DEVREF can make a major contribution to the domain of e-training in mines and is transferable and customisable beyond its initial application. The process flow of the research thus moved beyond merely providing a solution to a complex real-world problem and became a classic DBR study with dual outcomes, namely a practical real-world solution in the form of two VR training systems and a theoretical contribution in the form of the DEVREF evaluation framework. DEVREF evaluates the design of desktop VR training systems in the categories of instructional design, usability, VR systems design, and context-specific criteria for mining. The use of DEVREF is demonstrated by reporting the application of its criteria in evaluating the two VR training systems. Heuristic evaluation, end-user surveys, and interviews were used as evaluation methods. A third contribution is methodological, in that this work proposes a new DBR process model and an interaction design lifecycle model suitable for VR training systems. / Computing / D. Phil.
