Matrix for assessing and evaluating the impact of mobile phones for development in rural communities : a case study of Phake Rebone community

Modiba, Florah Sewela 12 1900 (has links)
Rural communities have been disconnected from the global world in the past due to lack of infrastructure that rendered connectivity a challenge for them. Recent developments in information and communication technology (ICT) have led to improved connectivity in these areas. As a result, mobile phones have become ubiquitous in these rural communities. A matrix was proposed in this study in order to evaluate and assess the impact of mobile devices on development of the rural communities. Existing measurement tools have not yet explored how the usages of mobile phones and other ICTs are impacting the lives of people in rural communities of South Africa. The aim of this study was to understand the existing criteria used to measure the impact of ICTs in rural communities. This was be achieved by focusing on the use of mobile phones in the community of Phake Rebone, taking into account different users. Once this was established, the study had a primary objective to design a matrix that would assist in evaluating and assessing the impact of a mobile phone in social activities such as learning, business and governance. This was achieved by using a case study method, employing qualitative and quantitative research methods. Cases within a case study were used to uncover how the core groups within the community used the mobile phone. A mixed method approach was used in data gathering and analysis to enable the researcher to identify usages and challenges related to the mobile phones. Data was collected from 401 participants and was analysed through the computer-aided tools such GoogleDocs and Microsoft Excel. The findings of the study showed a greater usage of the mobile phone. The literature findings of the use of the mobile phone for basic communication as well as growing adoption of applications such as social media and Internet were confirmed. The use in community related activities and work purposes that impacted the community members were minimal. The need of training to gain knowledge on how to use the device more effectively was established. The proposed matrix therefore seemed v relevant not only to measure impact but also to highlight the areas in which the community members can be trained on. The noted usage trends and needs by the community were then used to formulate indicators that could be used for the matrix. The indicators were then used to develop a matrix that could be used by community members and other interested parties to measure the impact of mobile phone on development of the users. The results of the matrix were also proved to be efficient in assisting individual users in recording the skills acquired through the use of the mobile phone. The matrix can be used in consultation with the guidelines that were formulated to ensure that each user, particularly from rural communities, benefits from such an evaluation tool / Development Studies / D.

The relationship between facilitation, computer software and the learner in teaching a computer-integrated lesson : an experimental design

Williams, Anthony Marlon 10 July 2009 (has links)
The aim of the research was to investigate the relationship between facilitation, computer software and the learner in teaching a computer-integrated lesson. South Africa has recently changed their education system from that of content-based to that of outcomes-based. With these changes came the introduction of e-Education. The Government e-Education goal is that every South African learner in the general and further education and training bands will be ICT (Information and Communication Technology) capable by 2013. Educators are expected to facilitate these classes without having being trained as facilitators in a computer environment. Most educators’ follow an instructivist mode of teaching and the researcher decided to do a case study at a school in the Western Cape to investigate the role of an educator in a computer environment. The researcher also wrote the computer-mediated software for the educator to use in his lesson. The software was written for a lesson on Physical Science which was not the field of study of the educator. The educator, however, is a computer technician. These issues raised questions as to what the methodology of teaching of this educator would be, how would the learners interact with the facilitator and the content and to what degree learning would take place with regards to transfer of skills and knowledge. From the literature survey the researcher compiled a checklist of what the role of an educator in a computer environment should be whereby the educator was assessed. A questionnaire was compiled whereby the learners evaluated the software that was used for this computer integrated lesson. The learners had to write a pre- and post-test to determine whether content was transferred in this lesson and they were asked to perform a practical experiment to determine their skills. This dissertation shows how good facilitation, coupled with pedagogically well-designed software and good learner participation leads to a successful learning community.

An investigation into the interaction between multiple intelligences and the performance of learners’ in open-ended digital learning tasks

Kafanabo, Eugenia Joseph 16 July 2008 (has links)
In this study, I investigated the interactions between multiple intelligences and performance of learners in open-ended digital learning tasks, and to suggest possible approaches to the teaching and learning process using computers in Tanzania. With the current introduction of computers in the education system in Tanzania, the qualities of instruction and learner participation in learning computer application skills and achievement have not necessarily shown improvement (Nelson, Post,&Bickel, 2003; Tilya, 2003). It is imperative for computer teachers to know the pedagogical strategies that can help them use the current technology effectively. Researchers in instructional design have suggested instructional methods that incorporate methods that encourage the use of learner-centered instruction, incorporating activity oriented methods, and problem solving that are designed around real-world problems (Huba&Freed, 2000). Learners will be able use their knowledge effectively, reveal their uniqueness as learners, and learn computer application skills in a social setting (Gardner, 1983; Wiggins, 1993, 1998; Teele, 2000; Huba&Freed, 2000). The theory of multiple intelligences by Howard Gardner (1983) was used as the theoretical framework for this study. The theory postulates that that everybody has at least eight intelligences which reflect different ways of interacting with the world. In an effort to achieve quality learning, learning must be based on multiple approaches with a series of activities which are authentic in nature and have to be completed by the learners. The study was conducted in Tanzania using a qualitative research design. Four secondary schools were selected and 40 learners doing computer studies course participated in the study. Four intelligences from the theory of multiple intelligences were assessed: logic-mathematical, verbal-linguistic, visual-spatial and interpersonal intelligences. Assessment was done using performance assessment procedures. The findings indicated that there are distinctive intelligence profiles apart from the four intelligences that were investigated in this study. Despite the intelligence profiles of the learners, didactical issues that will enhance ICT adoption in the education environment are important. These include the use of authentic tasks, performance assessment to acknowledge learners unique performance abilities across several intelligences and teachers familiarization in the use of performance assessment procedures. / Thesis (PhD (Curriculum Studies))--University of Pretoria, 2008. / Curriculum Studies / unrestricted

Elementary Logic as a Tool in Proving Mathematical Statements

May, Bruce Matthew January 2008 (has links)
>Magister Scientiae - MSc / An analysis of South African school mathematics results indicates that one of the problem areas in the mathematical performance of learners is proof and proving. In an endeavour to improve the mathematical proving ability of first year students at UWC, the MAM 112 class (a first year elective mathematics course) was taught a course in elementary logic. In the initial part of the study, logic puzzles were utilized as a tool to teach students to make logical connections between and from mathematical statements using the rules of inference. Subsequently research was done to determine if knowledge and understanding of logic would translate into improved proving abilities of students. To put proof and proving into perspective the origins and functions of proof was explicated and proving in South African schools was investigated. Consequently reasons are advanced for the dismal high school mathematics results in terms of proof and possible solutions are discussed. Recent discoveries of neuroscience are utilized to delineate the brain structures and cognitive processes involved in learning so as to gain a better understanding of the learning of mathematics. The findings of neuroscience, cognitive psychology and educational psychology are employed to elucidate the influence of emotion, confidence, experience and practice on the learning of mathematics in order to determine which factors can be applied to improve the proving abilities of students. The findings of the study indicate that knowledge of logic does help to improve the ability of students to make logical connections (deductions) between and from statements. The results of the study, however, do not indicate that knowledge and understanding of logic translates into improved proving ability of mathematical statements by students.

The use of mobile phones in disseminating agricultural information to farmers in Mashonaland west province of Zimbabwe

Mabika, Benhildah 11 1900 (has links)
The study investigated the use of mobile phones in disseminating information on agriculture to the farming community of Mashonaland West Province of Zimbabwe, with a view to improving the coverage gap created by the available initiatives. Relevant literature on the available and successful mobile phones agricultural information dissemination platforms were extensively reviewed, taking into consideration the Mashonaland West Province farmers’ information needs. Formats, channels and sources currently being used to transmit agricultural information to farmers were investigated. Barriers to the use of mobile phones in transmitting agricultural information were as well investigated. Data was gathered on the farmers’ access to mobile phones and ownership of mobile phones. The survey research methodology was used for data collection because the research involved a large sample in a widespread geographical area. Quantitative research approach was used and questionnaires were used for data collection. The respondents for the study comprised farmers, network providers and other agricultural stakeholders in the province. A sample of 384 farmers, and 13 network providers and other stakeholders participated in the survey. Quantitative data was analysed using the the SPSS software while the little qualitative data which was available was analysed through content analysis. The findings of the study indicated that farmers in Mashonaland West Province of Zimbabwe were willing to get updates on agricultural information via cell phones. However, majority of the farmers could not afford the high mobile data tariffs being charged by network service providers, and the costs of subscription charged by the available agricultural information dissemination platforms. The study mainly recommended that the government should establish mobile phone agricultural information dissemination platforms that can be accessed by farmers for free or that which will charge affordable rates. The study adds to the existing knowledge on how mobile phones can be used in disseminating agricultural information to farmers. / Information Science / D. Inf. (Information Science)

Обучение старшеклассников лексике с применением информационно-коммуникационных технологий : магистерская диссертация / Teaching vocabulary to high school students with the assistance of information-communication technologies

Ушаков, Ю. Н., Ushakov, Yu. N. January 2024 (has links)
В современном мире постоянное развитие технологий влияет на все сферы человеческой жизни, в том числе и на образовательный процесс. Меньше полувека назад данные хранились на громоздких вычислительных машинах и обрабатывали объём информации, равный нескольким книжным страницам, однако сейчас наши мобильные устройства способны на гораздо большее, чем большие стационарные компьютеры. Технологический прогресс также затронул и информационно-коммуникационные технологии, прошедшие долгий путь от средств радиосвязи до телевидения, а затем до Интернет-стриминговых сервисов. Данные технологии широко интегрировались в образовательную систему, создавались специальные обучающие радиопередачи, телепрограммы, затем появились компьютерные приложения, помогающие осваивать иностранные языки, широкое распространение мобильных устройств дало начало мобильным образовательным программам, таким как Quizlet, программы, обучающей лексике с использованием технологий флеш-карточек. Эффективность использования данного приложения для изучения лексики была доказана множество раз во многих исследованиях [49] [58] [67] [72], однако при использовании элементов мобильного обучения с данным онлайн-сервисом при обучении учащихся среднеобразовательных учреждений не проводились, доказательство эффективности подобного обучения помогло бы интегрировать данное приложение в образовательный процесс. Актуальность исследования обусловлена дальнейшей цифровизацией процесса образования, популяризацией гибридного и мобильного обучения, необходимостью апробации приложения Quizlet в реалиях общеобразовательного учреждения. Целью работы является изучение теоретических и практических аспектов использования информационно-коммуникационных технологий в обучении старшеклассников иноязычной лексике. / In the modern world constant technological development affects all parts of human life, including the education process. Less than half a century ago data used to be stored on huge calculating machines, which could only process the amount of information equal to several book pages, but now our pocket digital devices are capable of more than personal computers. Technological progress has also affected information-communcation technologies, which have developed from radio broadcasting to television, and then to modern Internet streaming services. These technologies were widely included into the education process, with special educational broadcasts, television shows, then pc language learning assisting applications were developed, then a wide availability of digital pocket devices gave way to language learning mobile applications, such as Quizlet, a program that assists in learning foreign language vocabulary through flash-card technology. Effectiveness of the usage of this application in learning foreign languages has been proven in many research works [49] [58] [67] [72], but there were no studies of effectiveness of using this application in the conditions of secondary education establishments, and proof of effectiveness of such education approach could help to integrate this application into educational process. The relevance of the research is based on further digitalization of educational process, popularization of mobile and hybrid education, necessity to try Quizlet application in the conditions of secondary education establishment. The purpose of the research is to study theoretical and practical aspects of using information-communication technologies in teaching high-school students foreign vocabulary.

Exploring the Diffusion Potential of a Collaborative Mobile Platform for Disaster Management and Relief

de Mendonca Salim, Joao 01 January 2024 (has links) (PDF)
This thesis describes the creation of a collaborative digital platform for disaster management and relief, focusing on the case study of the city of Petrópolis natural disaster in February 2022. The frequency and intensity of natural disasters are rising, necessitating efficient and timely disaster response efforts. This thesis details the development of a software application that fosters collaboration among governmental agencies, emergency services, non-governmental organizations (NGOs), and civil society to enhance logistical planning and situational awareness during disasters. The proposed platform harnesses the power of social networking and leverages the ubiquitous presence of smartphones equipped with cameras, GPS, and sensors to gather crucial real-time data. Through a secure and user-friendly interface, verified stakeholders can access essential information while the public contributes valuable data through their smartphones. The platform ensures reliable data collection and dissemination by analyzing metadata, assessing human needs, empowering decision-makers with up-to-date information, and providing verified information channels and real-time data analysis. The platform seeks to minimize overlapping efforts, reduce mismanagement of resources, and ultimately save lives and livelihoods in disaster-stricken areas.

Knowledge management practices in rural areas of South Africa

Mbhalati, Oliver Jan 28 September 2011 (has links)
This research report captures a detailed exposition of an investigation on Knowledge Management (KM) practices in public and private sector entities in three industries (health, education and business loans) of Limpopo province – a proxy of the rural areas of South Africa. The investigation was necessitated by a need to understand KM in organisational context experiencing constraints in terms of resources that enable KM. It was found through an intensive literature review that there were very few empirical studies on KM practices of organisations operating in the rural areas, particularly in Africa. The theoretical framework of the study emanates from the knowledge-based view which has been popularised by the seminal work of Peter Drucker and Nonaka in the early half of the 90s. The knowledge-based view as presented in chapter 2 recognises the strategic role of knowledge in organisations. Its genesis is traced from the theories of classical scholars such as Socrates, Plato and Aristotle. Various empirical studies of entities which have adopted the knowledge-based view are presented in chapter 2 of this report. The researcher observes from an intensive KM literature study that the average modern organisation could be categorised as knowledge-intensive considering that knowledge workers constitute the majority of its workforce. The definitions of a knowledge-based organisation and knowledge workers are presented in the operational definitions of key concepts. Arising from the identified gaps in KM literature as presented towards the end of chapter 2, this study was conducted as a comparative study between public and private sector entities in three research industries focusing on their extent of ICT application and degree of knowledge-oriented social factors for information and knowledge sharing. The investigation was guided by three research objectives as discussed in chapter 1 of this research report. The main purpose of the study was to answer two fundamental research questions as reflected in chapter 1. In answering the two research questions, the researcher identified four research hypotheses in line with the findings established from KM literature. These hypotheses are discussed in chapter 2 of this report.The underlying hypothesised statement guiding the study was to determine whether there were any significant differences in KM implementation between public and private sector entities in the three research industries in terms of four research constructs. These are: application of ICTs for knowledge and information sharing, degree of achievement of knowledge-based outcomes, tacit knowledge acquisition and the degree of knowledge-oriented social factors. Organisational culture, organisational structures, human resource practices and leadership comprised the social factors tested in the study. The research data were collected through a mixed research design approach combining the advantages of a survey instrument and interviews (this is fully reflected in chapter 3 of this research report). The research results (as presented in chapter 4) pointed to some form of significant differences in KM implementation between public and private sector entities in the education and business loans industry, but there were no significant differences in KM implementation between public and private sector entities in the health industry. Arising from the findings of the study, a model for improved KM implementation is presented in chapter 4 (figure 4.16). It was found during the investigation that all the research entities approached KM implicitly through KM related practices. KM related practices were found to be far more entrenched in the health industry (both public and private sector entities), the private sector entities in the education and business loans industries than was the case with the public sector entities in the education and business loans industries. In the entities where KM related practices were found to be entrenched, there were concerted efforts towards improved organisational processes. The study has managed to unravel the importance of KM related practices in laying the foundation for a formalised KM approach. / Graduate School of Business Leadership / D.B.L.
