Girls who have high aptitude in math are not entering careers related to science, technology, engineering, and math (STEM fields) at the same rate as boys. As a result, female students may have fewer employment opportunities. This study explores one potential way to reduce the gap between male and female career aspirations and choices. Specifically, it looks at the impact of bringing women with careers in math- and science-related fields into high school classrooms as role models. The study uses surveys to measure pre- and post-visit perceptions of science and scientific work as well as student's short-term interest in math and science courses. In addition to these surveys, student comments were collected about the role model visits. While the overall study yielded little statistical significance, it also indicated that the role model visits had some impact on student perceptions and choices and raised questions that warrant further study.

Indiana University-Purdue University Indianapolis (IUPUI) / Recent technological applications have made the life of people too much dependent on Science, Technology, Engineering, and Mathematics (STEM) and its applications. Understanding basic level science is a must in order to use and contribute to this technological revolution. Science education in middle and high school levels however depends heavily on visual representations such as models, diagrams, figures, animations and presentations etc. This leaves visually impaired students with very few options to learn science and secure a career in STEM related areas. Recent experiments have shown that small aural clues called Audemes are helpful in understanding and memorization of science concepts among visually impaired students. Audemes are non-verbal sound translations of a science concept. In order to facilitate science concepts as Audemes, for visually impaired students, this thesis presents an automatic system for audeme generation from STEM textbooks. This thesis describes the systematic application of multiple Natural Language Processing tools and techniques, such as dependency parser, POS tagger, Information Retrieval algorithm, Semantic mapping of aural words, machine learning etc., to transform the science concept into a combination of atomic-sounds, thus forming an audeme. We present a rule based classification method for all STEM related concepts. This work also presents a novel way of mapping and extracting most related sounds for the words being used in textbook. Additionally, machine learning methods are used in the system to guarantee the customization of output according to a user's perception. The system being presented is robust, scalable, fully automatic and dynamically adaptable for audeme generation.

Abstract in English, Sesotho and Zulu / The occurrence of Open Distance and e-Learning revolutionized Higher Education Institutions for students to access instruction at anytime and anywhere. Students benefitted instruction of anytime and anywhere in one of the Technology Education courses in ODeL from the e-tutors. As a result of the support from the e-tutors, the curriculum was designed to place a strong emphasis on the design process as the core around which the teaching of the curriculum should revolve. However, it is still not clear how effective is the content knowledge which relates to the design process from the e-tutors. In acknowledgment from such a gap, this study aimed to determine the relationship between the e-tutors’ technological, pedagogical, content knowledge of teaching design process within Technology Education specialization. In order to achieve this purpose, two theories, namely Transactional distance and Connectivism were coined together with the Technological Pedagogical Content Knowledge (TPACK) framework to underpin the study. The philosophical worldview is pragmatism having employed mixed method. Participants in this study were 145 students who registered a year programme for two modules in the Bachelor of Education (B.Ed.) programme at a Higher Education institution were surveyed to collect the quantitative data. Data from the face-to-face semi-structured interviews were collected with five e-tutors from the research sites. Online observations data were collected from the e-tutor sites of the institution’s learning management system (LMS). The results suggest that e tutors still lack the technology knowledge in order to deliver the content aimed for the design process in an ODeL environment. Also, it was evidenced that the e-tutors have not acquired pedagogical strategies for driving the pedagogy for the design process in an ideal context of ODeL. It should also be borne in mind that findings for the content knowledge indicated that the e-tutors still lack the knowledge for exploiting content knowledge of the design process to suit an ODeL environment. These findings highlight a need for technology to support e tutors’ pedagogical strategies towards a meaningful understanding of the design process and its implications across ODeL contexts. / Ketsahalo ea Open Distance le e-Learning e ntlafalitse litsi tsa thuto e phahameng bakeng sa baithuti ho fihlella taeo nako efe kapa efe le kae kapa kae.

Gender stereotyping is a phenomenon found in all spheres of life. School children often have to bear the brunt of these prescribed roles and stereotypes. This study includes a literature review of the characteristics of a professional educator as well as the theoretical background on gender issues. It employed Participatory Action Research as a strategy with the aim to empower teachers to improve their classroom practice, and ultimately, to improve the teaching-learning dynamics for learners in the science and technology classrooms. The participants, who are science and technology teachers, are vastly different people whose one common goal it was to empower themselves and to change their classroom practice on a continuous basis. The study looks at some of the beliefs these teachers now hold after the intervention for promoting gender equality in the classroom. Science and technology are the domains of historically male-dominated fields, and by means of this study I aim to equalise the learning opportunities for both boys and girls. / Comparative Education / M.

This is an Action Research (AR) study with the senior phase Technology teachers at selected schools of Limpopo Province. The study was motivated by the fact that Technology Education is a foreign concept to many teachers and a new learning area in school curriculum both nationally and internationally. This was exacerbated by the many educational changes that took place in South Africa in the last 18 years. These changes include the overhauling of curriculum, which was the strategic and symbolic change since the first democratic election of 1994, but followed by its review. Thus, a new curriculum known as Curriculum 2005 (reviewed twice already) was developed in which Technology was introduced as a new subject. These changes drastically affected Technology Education and teachers’ coping demands on both the subject content and pedagogy escalated. In this study, AR, a strategy for a systematic, objective investigation with Technology teachers’ who are un- and under- qualified to teach Technology was considered. The study aimed at establishing intervention strategies to empower and emancipate senior phase Technology teachers in Mankweng Circuit from the said challenges above. Thus, the study sought to address the question: How could action research intervention be used to improve the teaching of senior phase Technology teachers who are un- and/or under-qualified? The intervention strategies were implemented through the AR cycles in spiral activities of planning, implementation and observation, action and reflection, whose principles were operationalized to develop participants from the situations that they face in their Technology teaching contexts. The study was designed from both critical theory perspective and participatory paradigm. The following instruments were used as a means to gather data: observations, interviews, questionnaires, field notes, video recording of lesson plans and logs of meetings. The study managed to come up with guidelines to develop and kick start AR with teachers. From the ii findings an AR model was developed to emancipate the un- and under-qualified Technology teachers. Themes from the challenges and AR were used to draft a six weeks plan to empower incapacitated Technology teachers. This investigation was shaped by the initial reflection or preliminary study conducted with the participants called reconnaissance study which revealed specific challenges that Technology teachers encountered daily in their classes. These challenges were turned into the themes, which together with the findings from the preliminary study and interview reflection per cycle were used to design the intervention strategies for the next main cycle. The findings of the study from both the preliminary investigation (presented in Chapter Two) and main AR (presented in Chapter Five) reveal an improvement in the teachers’ understanding and implementation of Technology – they were emancipated to a greater extent from the challenges prior to the AR intervention and post the AR intervention. It is true that coming together as AR co-researchers was the beginning of Technology teaching practice problem identification; keeping together was progressive in Technology teaching; but working together remains our success in Technology teaching then, now and in the future – post doctoral studies. / Curriculum and Instructional Studies / D.

This study on technology in the South African school curriculum investigates the nature and value of this subject as a catalyst in developing Foundation Phase learners’ creative thinking skills Technology as school subject is defined as the use of knowledge, skills and available resources to develop solutions to meet human needs and wants, taking social and environmental factors into account. Central to this subject, is the design process of investigating, designing, making, evaluating and communicating solutions to problems identified in the environment. The notion and nature of creativity as researched by respected psychologists and researchers over the last few decades, with particular reference to Matlin’s theory of problem-solving and creativity, provides a theoretical underpinning with the aim of linking the problem-solving nature of technology with creative thinking. A qualitative case study research project, comprising a sample of six Foundation Phase learners at an independent school, has been conducted. Key characteristics of qualitative educational research such as sensitivity, precision, verification, empiricism, natural setting, inductive data analysis, validity and reliability and triangulation, have been taken into consideration. This study highlights the potential of technology as a school subject that provides learners with the opportunity to solve problems in creative ways and use authentic contexts rooted in real life situations. In addition, learners are afforded the opportunity to work collaboratively with others and engage in meaningful activities in the indoor and outdoor environment. Technology as a school subject in the Foundation Phase catalyzes learners’ creative thinking and problem-solving skills and provides a solid foundation for preparing young citizens for the demands and challenges of the 21st century. / Curriculum and Instructional Studies / D.

The purpose of this study is to formulate guidelines upon which Technology Education can be put into operation in the South African schools with specific reference to standard eight students. The objective is to formulate Technology Education guidelines suitable for and within the broad framework of the South African curricula. In attempting to translate Technology Education curriculum to South Africa, the author explores the state of advancement in Technology Education in various developed and developing countries. The status, principles and theoretical assumptions of Technology Education are also explored. The role of the teacher in the Technology Education programme is also discussed. Guidelines for Technology Education, including Technology Education teaching strategies, guidelines for Technology Education assessment standards and guidelines for integrating Technology Education, Science and Mathematics are also formulated. The author qualifies the significance of Technology Education in South Africa through a pilot study over a year. The subjects of this (pilot) empirical study consisted of a total of 175 standard eight students, 77 of who were in a control group, who had received no tuition in Technology Education. A group of 98 received tuition in Technology Education for a year. The normal end of the year examination in 1994 measured academic performance of the two groups. Performance in 1993 is also used in the statistical analysis. The Univariate Analysis of Variance (ANOVA) is applied in the analysis of data. Statistically significant differences are found between the academic performance of these two groups in relation to the overall Examination marks, English, Science and Mathematics marks. Statistically significant differences are also found between the 1993 and 1994 performance of the experimental group after receiving Technology Education tuition in standard eight in terms of the overall Examination, marks, English, Science and Mathematics marks. In the control group, no statistically significant differences were evidenced in Mathematics, English and Science when comparing marks in 1993 and in 1994. It is only applicable in the average Examination mark. These results confirm the role that Technology Education plays in enhancing performance in Science and Mathematics including English. / Curriculum and Institutional Studies / D. Ed. (Didactics)

Curriculum 2005 together with its learning areas has been introduced in South Africa in 1998. All learning areas, except Technology Learning Area, are not new. Technology is growing so rapidly that it gives so many challenges to people. These challenges include making technology part of our curriculum, formulating and adapting technological solutions to problems people may experience. We have to ask ourselves what technology or Technology Education means. Therefore, this study provides the meaning and the rationale for Technology Education in our curriculum. This study also attempts to shed light on the form of training educators should attend for Technology Education. Although there are different methods of training, for example PRESET and INSET, this study concentrates on various forms of INSET. INSET is chosen because it is a means through which the present need for Technology Education educators can be solved. The percentage of educators involved in part-time study will increase in relation to the number in full-time education. The closing down of some of colleges of education in South Africa reduces the use of PRESET and increases INSET as a means of educator training. The advantages of using INSET instead of PRESET are provided in this study. The National Teacher Audit of 1995 has shown that the quality of INSET in South Africa is poor. In addition, it seems the present ad hoc way of running INSET will not cope with challenges of training educators for Curriculum 2005 and Technology Education. Normally, INSET is the prime strategy for addressing problems in PRESET. Unfortunately, INSET has to train educators for Technology Education (Technology Learning Area) which was never touched by PRESET before. For this reason, this study provides an INSET model, guidelines and recommendations to make the suggested model of INSET work successfully. / Educational Studies / M. Ed. (Comparative Education)

Thesis (M.Tech.: Information Technology)-Dept. of Information Technology, Durban University of Technology, 2007 xv, 150 leaves, Annexures A-J / Over the years, computers have been introduced to many South African classrooms in an attempt to improve education, and this is true for Previously Technologically Disadvantaged (PTD) schools in Kwazulu-Natal with learners whose first language is isiZulu. However, frameworks of computer learning vary widely and there is a crucial need to understand how specific situational conditions either facilitate or constrain the implementation of computer-supported learning in these schools. This thesis discusses research undertaken to document the process of introducing localised OpenOffice.org.za software with an isiZulu interface into Information Technology education at PTD schools in the KwaZulu-Natal province. The thesis also documents the process of introducing a dual language medium in Information Technology at the Durban University of Technology. The study investigates the English language as one of the possible causes of the lack of understanding of computers by English second language learners.
