An awareness programme to improve participation of young women in the science, technology, engineering and mathematics (STEM) fields in South African universities

Toolo, Lineo Lynnette 06 1900 (has links)
The purpose of this study was to develop the i-STEM programme, an awareness initiative that would improve the participation of young women in the science, technology, engineering and mathematics (STEM) fields in South African universities. That would serve as an intervention measure to young women’s significantly low numbers in the STEM fields, causing a gender disparity in those fields. Young women are said to be overrepresented in the fields that are at a lower level, the so-called soft disciplines and of short-term duration at tertiary level. The STEM fields, on the other hand, are well-remunerated and high-status careers, perceived as the main solution for the unprecedented socioeconomic challenges that the world is experiencing, as a result of, mainly, climate change and lack of food security. The literature reviewed was focused on the participation of young women in the STEM fields in South Africa, Africa and globally, assisting the study to investigate the reasons for low numbers of young women in the STEM fields. The mixed method approach was of benefit to the nature of this study, a quantitative and qualitative enquiry. The study was conducted at two universities with completely different profiles, contact sessions and modes of content delivery. The third institution was the government department relating to higher education. For research design, data was collected from 111 participants who were involved with the STEM fields and/or university education. Two (2) lecturers, two (2) government officials and two (2) young female students were interviewed and 105 other participants completed the questionnaires. Some data were collected from participating institutions’ documents. Interpretation and analysis of such data, was done through concurrent, triangulation design, where data collection was done concurrently, i.e. in the same phase, in both the quantitative and qualitative manner. The main findings blamed the different ways in which boys and girls were socialised in their communities. Girls were more exposed to matters pertaining to food and caring while boys were more exposed to cars and machines, resulting in girls preferring socially orientated careers and the boys, mechanical ones. Those findings were used as the impetus to construct Phases 1, 2 and 3 of the developed awareness programme, i.e. ‘Identification’, ‘Induction’ and ‘Implementation’, whereby the departments of Basic Education and Higher Education and Training, together with universities, would identify learners and students as mentees and mentors, who will become the advocates for breaking the above stereotypes. Another discovery was that there is an element of cultural stereotyping in society, that the STEM fields were difficult and therefore meant for men, since they are supposed to be more demanding and not for women as soft targets; hence the environment was unsupportive of women. It also related to the classification of certain jobs as men’s and others as women’s territory. That theory was further extended through the finding that the STEM fields were more-costly than the social sciences and that most of them require a longer study period. As a result, young women who anticipate becoming mothers and wives, avoid them as careers, in consideration of their future cultural roles. Those findings influenced the last four phases of the i-STEM programme, i.e. ‘Impression’, ‘Integration’, ‘Intensification’ and ‘Ignition’, whereby cultural and classist stereotypes would be determined through baseline information and rooted out by synergy in terms of resources, research and effort by local, national and international stakeholders, as guided by the programme. / Curriculum and Instructional Studies / D.

The development and evaluation of a custom-built synchronous online learning environment for tertiary education in South Africa

Halse, Michelle Louise 23 February 2008 (has links)
The Departments of Computer Science and Information Systems at Rhodes University currently share certain honours-level (fourth year) course modules with students from the corresponding departments at the previously disadvantaged University of Fort Hare. These lectures are currently delivered using video-conferencing. This was found to present a number of problems including challenges in terms of implementing desired pedagogical approaches, inequitable learning experiences, student disengagement at the remote venue, and inflexibility of the video-conferencing system. In order to address these problems, various e-learning modes were investigated and synchronous e-learning were found to offer a number of advantages over asynchronous e-learning. Live Virtual Classrooms (LVCs) were identified as synchronous e-learning tools that support the pedagogical principles important to the two universities and to the broader context of South African tertiary education, and commercial LVC applications were investigated and evaluated. Informed by the results of this investigation a small, simple LVC was designed, developed and customised for use in a predominantly academic sphere and deployment in a South African tertiary educational context. Testing and evaluation of this solution was carried out and the results analysed in terms of the LVC’s technical merits and the pedagogical value of the solution as experienced by students and lecturers/facilitators. An evaluation of this solution indicated that the LVC solves a number of the identified problems with video-conferencing and also provides a flexible/customisable/extensible solution that supports highly interactive, collaborative, learner-centred education. The custom LVC solution could be easily adapted to the specific needs of any tertiary educational institute in the country, and results may benefit other tertiary educational institutions involved in or dependant on distance learning.

An investigation of an undergraduate course module on the ethical aspects of information systems

Charlesworth, Matthew January 2005 (has links)
An increased emphasis is being placed on ethics in Information Systems. An investigation of: the relevant literature which highlighted the growth of, and importance in understanding the moral philosophies which underlie Computer Ethics; and the official curricula recommendations that have increasingly and consistently recommended inclusion of courses describing the Social, Professional and Ethical responsibilities of Information Systems Professionals; and informed by the observations from two empirical Studies that showed the extent of unethical behaviour, and how this behaviour is diminished in those who have received formal tertiary level education resulted in a proposed new course module on Ethics in Information Systems. The module follows a sandwich-approach whereby two stand-alone modules are conducted on either side of integrated Computer Ethics content within the rest of the curriculum.

Key Factors Influencing Retention Rates among Historically Underrepresented Student Groups in STEM Fields

Premraj, Divya 12 1900 (has links)
The aim of the study was to identify the factors that have an influence on the completion rates of undergraduate students in the fields of science, technology, engineering and mathematics (STEM). Using Tinto's retention rate theory as the theoretical foundation, data were collected from freshman who were enrolled in the years 2005 to 2008. Results showed gender and first-generation status were significant predictors of STEM completion and time taken to complete the degree. Institutional bias played a role in race/ethnicity not being a factor affecting completion rates, as this study was conducted at a Predominantly White Institution. SAT scores and first and second-year college GPA showed to have the most prominent influence on both STEM completion rate and time taken to complete the degree. Females with higher first-year college GPA and higher high school rank finished faster. Similar results were found with first-generation students as well. Students belonging to ethnic minority groups with higher SAT scores and college GPA had greater success in STEM fields as well. The study results can be used to increase completion rates of underrepresented students in the STEM fields, given what we know about the interactions between underrepresented student groups and the most important predictors.

Investigating the problem-solving proficiency of second-year Quantitative Techniques students : the case of Walter Sisulu University

Bester, Lynette 07 1900 (has links)
Quantitative Techniques is traditionally a subject with a poor pass rate at Walter Sisulu University. In search of a turnaround strategy, the purpose of this study was to determine the level of problem-solving proficiency of Quantitative Techniques students, which is suspected to influence achievement in this subject. A descriptive survey design was used in this research. Second-year ND (Marketing) students (128) took part in the study. A questionnaire and a written test were used to collect data. A profile of participants’ problem-solving was determined. Their weaknesses and strengths in problem-solving were investigated. The problem-solving proficiency of participants with regards to the biographical variables of Gender, Age, Mathematics background and whether they took Data Handling training at school or not were explored. A model, based on Polya’s four stages of problem-solving, was used to measure the students’ level of problem-solving proficiency, which was 59,16%. Findings suggest that the students achieved highest in understanding a problem (72,29%) and making a plan to solve the problem (73,77%). They are weakest at interpreting their results (29,38%). MANOVA results showed no statistical significance for the biographical variables. The univariate results suggest that age, Data Handling training at school and Gender could affect problem-solving proficiency. Since the findings of this study indicate a strong relationship between participants’ problem-solving proficiency and their actual achievement, some intervention is recommended. An intervention could be in the form of a section on problem-solving in the course, supplemental instruction or an introductory course. Course and curriculum content should be revised to address students’ proficiency in problem-solving. / Mathematical Sciences / M. A. (Statistics Education)

The use of ALICE, a visual environment for teaching and learning object-oriented programming

Dwarika, Jeraline 23 April 2014 (has links)
University students learning object-oriented programming (OOP) encounter many complexities. This study undertook empirical research aimed at analysing learners’ interactions with the Alice visual programming environment, which seeks to engage and motivate learners to grasp concepts of OOP, whilst creating animated movies and video games. A mixed-methods approach was employed, using questionnaire surveys and interviews to investigate learners’ experiences with Alice and their understanding of OOP. Findings indicated that learners lacked problem-solving abilities; were unable to grasp programming concepts on an abstract level and spent insufficient time practicing programming exercises. Alice proved to be an effective tool in helping to address these challenges and in improving learners’ grasp of OOP. Learners found Alice to have good usability. Furthermore, test and exam results revealed a statistically significant difference between performances of learners who had been taught Alice in comparison to similar learners who were not exposed to the Alice intervention. / Computing / Information Systems / M.

Studying science and engineering at UCT : students' background, experience of science an reasons for studying science or engineering

Laugksch, Diane 03 1900 (has links)
Thesis (MPhil)--University of Stellenbosch, 2007. / ENGLISH ABSTRACT: It is the contention of this study that competence in science and mathematics is a necessary condition for access to higher education, but that it is a general interest in science that will inspire learners to pursue careers in science and technology. The objective of this study was to develop a profile of the individual who chooses to study science and engineering. The three research questions were, firstly, what is the background profile of a group of learners who have decided to study science and engineering? Secondly, what are the characteristic features of the school-science experience of these learners? Lastly, what are the factors that learners think most influenced their decision to study science and engineering? This study was formulated as having a descriptive purpose and hence a survey research design was used. Self-reported retrospective data were collected using a questionnaire which was designed with reference to a number of sources (e.g., Woolnough, 1994). After piloting the questionnaire, it was administered to all firstyear students registered in the faculties of Science and Engineering at the University of Cape Town. A total of 204 first-year science and 247 first-year engineering students formed the final sample of this study. Quantitative analysis of the students’ responses showed that 66% of respondents were male. The majority of female students were registered in the science faculty. English was the home language of 55% of the sample, with 32% of students reported speaking one of the other nine official languages at home. Parents, career counselors and teachers most influenced students’ decision to study science or engineering. The vast majority of respondents took Physical Science at school. Students’ experiences of school science were diverse. Students’ responses generally reflected a poor commitment on the part of schools to expose students to noncurriculum activities generally thought to promote an interest in science. Overall, the majority of students reflected an enthusiasm for learning to do science through scientific experiments, albeit with preference for a teacher-driven approach to classroom activities. Personal motivation, receiving a bursary, and access to information were the main factors that students said influenced their decision to study science and engineering. While information received at a careers open day and participating in a school science competition was crucial for science students, engineering students showed a general curiosity for science, for knowing how things work, and for creating and designing things. For most African students information received at a careers open day was important, while a curiosity for science and receiving a bursary were equally important in influencing non-African students to pursue further study in science or engineering. The results of this study suggest that what parents say, and the information that learners have access to, is important to the decisions that learners make in regard to future careers in science and engineering. It is suggested that future strategies for promoting science in general must include parents, teachers and senior learners in the dissemination of general information about science, about people in science, about using science in everyday life, and about the possibilities for further study in science and engineering. / AFRIKAANSE OPSOMMING: Dit is die uitgangspunt van hierdie ondersoek dat vaardigheid in die wetenskap en wiskunde ‘n noodsaaklike voorwaarde is vir toegang to tersiêre onderwys, maar dat ‘n algemene belangstelling in die wetenskap leerders sal inspireer om loopbane in die natuurwetenskappe en tegnologie te volg. Die doel van hierdie ondersoek was om ‘n profiel te ontwikkel van die individu wat die natuurwetenskappe en ingenieurswese kies as studierigting. Die drie navorsingsvrae was, eerstens, wat is die agtergrondsprofiel van leerders wat besluit om in die natuurwetenskappe en ingenieurswese te studeer? Tweedens, wat is die kenmerkende eienskappe van hierdie leerders se skoolervaring? Laastens, watter faktore dink hierdie leerders het hulle besluit om in die natuurwetenskappe en ingenieurswese te studeer, die meeste beïnvloed? Hierdie ondersoek is beskrywend van aard en dus is ‘n steekproef as navorsingsontwerp gebruik. Selfgerapporteerde retrospektiewe data is ingesamel deur middel van ‘n vraelys wat ontwerp is met verwysings na ‘n verskeidenheid bronne (bv., Woolnough, 1994). Die vraelys is versprei aan alle eerste-jaar geregistreerde studente in die Natuurwetenskappe en Ingenieurswese Fakulteite by die Universiteit van Kaapstad, nadat ‘n voortoetsing van die vraelys uitgevoer is. ‘n Totaal van 204 eerste-jaar natuurwetensakppe en 247 eerste-jaar ingenieurswese studente was deel van die finale steekproef van hierdie ondersoek. Die kwantitatiewe ontleding van die studenteterugvoer toon dat 66% van die respondente manlik is. Die meerderheid vroulike studente was geregistreer in die natuurwetenskappe fakulteit. Engels was die huistaal van 55% van die steekproef, en 32% van die studente het aangedui dat hulle een of meer van die ander nege amptelike landstale praat. Ouers, beroepsvoorligters en onderwysers het die meeste invloed gehad op die studente se besluit om in die natuurwetenskappe of ingenieurswese te studeer. Die oorgrote meerderheid respondente het Natuur- en Skeikunde op skool geneem. Studente se skoolervarings en ervaring van die wetenskap op skool was uiteenlopend. Studente se terugvoer het in die algemeen gedui op ‘n swak verbintenis van skole tot die blootstelling van studente aan niekurrikulêre aktiwiteite wat oor die algemeen belangstelling in die wetenskap kweek. Die meerderheid studente het in die geheel ‘n entoesiasme getoon om meer te leer van die wetenskap deur die uitvoer van wetenskaplike eksperimente, hoewel met ‘n voorkeur vir ‘n onderwyser-gedrewe benadering tot klaskamer aktiwiteite. Persoonlike motivering, om ‘n beurs te ontvang, en toegang tot inligting is deur studente aangedui as van die vernaamste faktore wat ‘n invloed op hulle keuse van die natuurwetenskappe en ingenieurswese as studierigting gehad het. Die inligting wat die natuurwetenskappe studente ontvang het by beroepsgeoriënteerde opedae en deelname in ‘n skool wetenskapskompetisie was beslissend in hulle besluit. Die ingenieurswese studente daarteenoor het ‘n algemene nuurskierigheid vir die wetenskap en hoe dinge werk, hoe om dinge te skep en te ontwerp, getoon. Die inligting wat swart studente by beroepsgeoriënteerde opedae ontvang het, was belangrik, terwyl ‘n wetenskaplike nuuskierigheid en die toekenning van ‘n beurs ‘n ewe belangrike invloed gehad het op ander studente se keuse om verdere studie in die natuurwetenskappe of ingenieurswese voort te sit. Die resultate van hierdie ondersoek dui daarop dat wat ouers sê, en die inligting waartoe leerders toegang het, belangrik is vir die besluite wat leerders neem met betrekking tot toekomstige loopbane in die natuurwetenskappe en ingenieurswese. Daar word voorgestel dat toekomstige strategieë vir die bevordering van die wetenskap in die algemeen ouers, onderwysers en senior leerders moet insluit in die verspreiding van algemene inligting oor die wetenskap, oor mense in die wetenskap, oor die gebruik van die wetenskap in die alledaagse lewe, en die moontlikhede van verdere studies in die natuurwetenskappe en ingenieurswese.

Lighting the Fire: How Peer-Mentoring Helps Adult Learners Increase Their Interest in STEM Careers: A Case Study at the Community College Level

DeTurk, Patricia Marie 08 August 2013 (has links)
In the U.S., about 7,000 high school students drop out each school day, representing a loss of talent and ability. Concurrently, there are a decreasing number of enrolled students taking science-related courses at the high school and college levels. Adults, who return to obtain their General Educational Development (GED) certification, are an untapped resource that could be steered toward STEM (Science, Technology, Engineering and Mathematics) careers. In this case study, 15 GED students were shown a STEM video, and then peer mentored by 8 CLA (Clinical Laboratory Assistant) students, in a student-centered laboratory experience. Individual interviews of the GED students prior to and after the treatment were used to assess STEM attitudes. Additionally, the CLA peer mentors were given self-assessments regarding their level of self-efficacy. The most marked difference in the pre- and post-treatment data was with the male GED students. Initially, only 2 of the 7 had definite career goals, 5 with undefined career goals, with 4 showing no interest in STEM. After the treatment, 6 exhibited interest in pursuing STEM education or employment. The female GED students' interest remained unchanged, resulting in the male and female students showing equivalent interest in STEM post-treatment. The CLA peer mentors showed an increase in self-efficacy using Bandura's four sources of self-efficacy in social cognition (1997). The preliminary results of this study suggest that interest in STEM education and STEM careers can be generated with peer mentored learning. (Contains 1 figure and 8 tables.)

Mulheres ma computação: percepções, memórias e participação de estudantes e egressas / women in computing: students and graduates perceptions, memories and participation

Castelini, Pricila 02 February 2018 (has links)
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) / Pesquisas do Instituto Nacional de Estudos e Pesquisas Educacionais (INEP), Censo da Educação Superior, Teses e Dissertações, apontam que os cursos de graduação na área de Computação são os com menor número de mulheres matriculadas. Assim, para compreender quais os fatores para esta disparidade, foram propostas, nesta pesquisa, três oficinas com estudantes e egressas de cursos da área de computação de uma universidade federal: a primeira foi uma atividade presencial com estudantes da área de Computação para entender as percepções e memórias destas pessoas; a segunda também foi uma atividade presencial com este mesmo intuito, porém, com egressas de Bacharelado em Sistemas de Informação (BSI) e Engenharia de Computação (EC); e a terceira, um espaço virtual para promover a participação e discussão sobre as memórias das egressas. Para essas três oficinas, utilizou-se uma prática de Design Participativo (DP), a Oficina de Futuro. O Design Participativo proporcionou que cada uma das atividades tivesse o desenvolvimento conduzido de forma diferente, pois a proposta de DP permitiu que as práticas fossem organizadas colaborativamente pelos participantes, o que difere dos dados obtidos por questionários, por exemplo. Os resultados destas aproximações trazem as percepções e memórias de estudantes e egressas sobre a participação de mulheres na área de Computação. Estes resultados encaminham que cabe à sociedade e à comunidade acadêmica promover discussões para a implementação de política de cotas para gêneros, promover mudanças, apontando para a igualdade de gênero, no ambiente escolar, no mercado de trabalho e nos papéis sociais. / In researches of National Institute for Educational Studies and Research (NIES), Higher Education Census, Theses and Dissertation, it was observed that undergraduate courses in Computing are those with fewer women enrolled. Accessing such information identifies that quantify data about women participation in Computing area is insufficient. Thus, to comprehend which factors to this disparity has proposed three workshops: first face-to-face workshop with students of Computing area; second also a workshop, however, with recent grads of Bachelor of Information Systems and Computer Engineering; and third a virtual space for collaboration on topics that involve the women participation in Computing, remote mode, in corais.org plataform, three workshops were with students and recent grads from the same Institution – Federal Technological University of Paraná – in Curitiba. The three workshops used Participatory Design (PD) practice - future workshop, however in each of them the development was different, because (PD) allowed that participants organized the approach collaboratively. The results bring perceptions and memories of students and recent grad about women participation in Computing, and these results point out that is up to society and to University, to promote discussions to implementing genre quotas, changes since childhood, at school, and the participation of parents and all the society; it is necessary to point to gender equality; labor market; opportunities; destruction of gender categories and the development of public policy for equity.
