Advantages and disadvantages of eLearning in primary and secondary schools in the context of developing countries
(2015) Temitope, Obafemi Samson; Eyono Obono, Seraphin Desire
Information and Communication Technologies (ICTs) are ubiquitous nowadays, and there are many situations where they are overall perceived either as advantageous or as disadvantageous; but there are other situations where it is unknown whether they are overall advantageous or disadvantageous. For example, ICTs are perceived as advantageous for communication, but texting during driving is perceived as worse than drinking while driving. Concerning for example eLearning which is the use of ICTs in education, the fact that it has not yet eliminated the problem of poor academic performance raises the question as to whether ICTs are advantageous or not in education especially when one considers their high cost. Therefore, the aim of this study is to examine the perceptions of educators on the advantages and disadvantages of eLearning. This aim will be subdivided into three types of research objectives: (a) to select from existing literature suitable theories that can be applied to the examination of educators’ perceptions on the advantages and disadvantages of eLearning; (b) to design a model of the factors affecting educators’ perceptions on the advantages and disadvantages of eLearning; (c) to empirically test the above announced model; (d) to propose recommendations on how to optimize the impact of eLearning. Objectives a, b, and d were accomplished through the review of existing appropriate literature on teaching and learning, and on eLearning; but objective c was met through a survey of 65 educators of Camperdown town schools in the Pinetown district of KwaZulu-Natal province of South Africa. The outcomes of these four objectives are as follows: (a) Constructivism, Progressivism, and Self-regulated learning can be used as suitable theories applicable to the examination of educators perceptions on the advantages and disadvantages of eLearning; (b) It makes sense to hypothesize that educators perceptions on the advantages and disadvantages of eLearning are affected by their demographics and by their adherence to learning theories; (c) Empirical test conducted by this study confirm that educators perceptions on the advantages and disadvantages of eLearning are affected by their adherence to constructivism and to progressivism; (d) It can be concluded that the impact of the use of ICTs on teaching and learning will be optimized through the deployment of constructivist and progressivist educators as champions of eLearning projects in schools.
Early introduction of cost-effective e-Learning ICTs in schools
(2015) Oyetade, Kayode Emmanuel; Eyono Obono, Seraphin Desire
One of the fundamental characteristics of technology is its ever-changing nature with the continuous release of new models and products almost on a daily basis. It is interesting to note that these new technologies seem to appeal more to the youth than to the old. This might explain why the content of some Information and Communication Technologies (ICTs), such as films, TV, and games, are sometimes released with well-defined age ratings, in order to provide guidance to parents and guardians on the suitability of such content for their children. What is surprising is that there are age restrictions for the content presented by ICT devices, but devices themselves do not have any defined age restriction. For example, movies which can be played on computers, have a well-defined age restriction; but computers themselves do not have any defined age restriction. This non-definition of age ratings for ICT devices is certainly a general concern, but it is also a major concern for the education domain which needs to determine the minimum age from which learners should be allowed to use ICTs at school. This problem of the non-definition of age ratings for ICT devices serves as a motivation for this study, whose aim is to determine the factors affecting educators’ perceptions on the age from which learners should be allowed to use ICTs at school. The research objectives unfolding from this aim are: i) To select appropriate theories and models on the factors affecting educators’ perceptions on the age from which learners should be allowed to use ICTs at school; ii) To design a conceptual model of the factors affecting educators’ perceptions on the age from which learners should be allowed to use ICTs at school; iii To empirically test the above conceptual model of the factors affecting educators’perceptions on the age from which learners should be allowed to use ICTs at school; and iv) To make recommendations on the design of eLearning initiatives in schools based on the results of the current study. These four objectives were achieved as follows through the content analysis of existing literature and a survey of 70 primary and secondary school educators from the Camperdown magisterial district in the KwaZulu-Natal province of South Africa: i) Specific personality and child development theories were selected as the theoretical foundation of this study; ii) The conceptual model proposed in this study gave rise to the following hypotheses: The demographics of an educator affect the full functionality, the health, and the self-actualisation of his or her personality as well as his or her perceptions on the age from which learners should be allowed to start using ICTs at school. The full functionality, the health, and the self-actualisation of the personality of an educator all affect his or her perceptions on the age from which learners should be allowed to start using ICTs at school; iii) The empirical testing of the above hypothesized model yielded the following results: the grade or class taught by an educator is the only demographic factor that affects the full functionality, the health, and the self-actualisation of his or her personality; the subject specialisation of an educator is the only demographic variable that affects his or her perceptions on the age from which learners should be allowed to start using ICTs at school; the full functionality, the health, and the self-actualisation of the personality of an educator all affect his or her perceptions on the age from which learners should be allowed to start using ICTs at school; and iv) One of the recommendation of this study is that eLearning pilot projects be designed in ways that clearly consider differences between educators from various subject specialisations. This study identified the need for more research on the effect of personality on the perceptions of educators on the age from which learners should be allowed to start using ICTs, not only at school as it is the case for this study, but also at home. The main contribution of this research is to have found that educators’ personality has an effect on their perceptions on the age from which learners should be allowed to start using ICTs at school, compared to the literature reviewed by this study which seems to be silent on the relationship between the personality of educators and the determination of the age when learners should be allowed to start using ICTs at school.
Examining the impact of the ethnoscience teaching philosophy on academic performance in introductory computer programming
(2021-09-20) Sofowora, Mayowa A.; Eyono Obono, Seraphin Desire
The mastery of the core technologies of the Fourth Industrial Revolution (4IR) seems to require a set of skills that are reputed to be difficult to learn. This also includes general STEM (Science, Technology, Engineering and Mathematics) related know- how where computer programming is considered by many as the new linking glue of the 4IR despite its reputation of being difficult to learn and to master. 4IR is credited with a wide range of advantages, such as improved production, communication and participation, but it also comes with several disadvantages, such as the widening of the digital divide and higher levels of unemployment, especially for unskilled people. In fact, computer programming and other STEM related skills are crucial for the optimization of the benefits of the 4IR and for the minimization of its disadvantages. This is why this study is examining the impact of a different type of teaching approach known as the ethnoscience teaching approach, a STEM teaching philosophy, on students’ academic performance in introductory computer programming. A content analysis of existing literature on academic performance factors was first undertaken, both for introductory programming and for STEM subjects, in order to design an aggregated theoretically sound model of academic performance factors for these two fields. That model was then partially empirically tested by this study first within a totally culturally neutral teaching approach, then with a quasi- experiment whose experimental group was taught and tested with the use of the ethnoscientific teaching approach and philosophy while the control group stayed with the conventional culturally neutral teaching approach. The results of this study indicate that the ethnoscience teaching approach significantly improves students' academic performance in introductory computer programming compared to the conventional teaching approach. They also indicate that students’ prior language and computing subject choices affect their performance in conventional but not in culturally sensitive introductory computer programming. The participants of this study were selected from the introductory programming 2018 class of the IT Department of the Durban University of Technology. Should the findings of this study be confirmed with more programming concepts and with different samples, they will confirm the intrinsic value of culturally sensitive computing education.
Examining the perceived reliability of cost effective e-learning handsets for teaching and learning in schools
(2015) Sofowora, Mayowa A.; Eyono Obono, Seraphin Desire
The use of mobile devices such as cell phones, smartphones, personal digital assistants and tablet computers is becoming prevalent in today’s world; and it is facilitating access to a vast amount of data, services and applications for the improvement of people’s lives. Advances in electronics and manufacturing technologies usually lead to the rapid release of newer and sleeker models with new features and capabilities. These newer models therefore render older models obsolete, and this pushes people to frequently replace their devices. The drawback of such frequent replacements is that a large number of devices are disposed and they end up as e-waste. The fact that e-waste constitutes a major hazard to human health and to the environment is the motivation behind this study whose aim is to examine the factors affecting the perceptions of teachers on the durability of cell phones in the e-learning context. This research aims was achieved through the content analysis of existing literature and through a survey of 67 secondary school teachers from the iLembe and UMgungundlovu district municipalities in the KwaZulu-Natal province of South Africa. The attribution theory was selected as the theoretical framework for this study, and it led to the identification of four independent variables (Demographics, Intention, Knowledge, and Actual use) and of one dependent variable (Perceived Durability). The results of this study indicate that teaching experience and school location are the only two demographics that affect other variables from this research: School location affects cell phone durability, and teaching experience affects cell phone usage intentions. These results also indicate that all the variables of this research are linked except for the relationship between knowledge and perceived durability. One of the recommendations of this study is the proposal of a three year cycle for cell phone renewals in schools mobile learning projects in order to manage e-waste through e-recycling, and this recommendation is based on the finding of this research that teachers believe that cell phones generally lasts between two to three years. The main contribution of this study is to have examined the durability of mobile phones in the e-learning context and this is something new compared to all the studies reviewed by this research.
Factors affecting computing students’ awareness of the latest ICTs
(2015) Adegbehingbe, Oluwakemi D.; Eyono Obono, Seraphin Desire
Education is constantly challenged by rapid technological changes both in terms of curriculum renewal and in terms of students’ awareness of these new technologies. This is the reason why the aim of this study is to analyse factors affecting computing students’ awareness of the latest ICTs. This aim is further divided into four research sub-aims: the selection of the relevant theories for this research; the design of an appropriate conceptual model to support it; the empirical testing of the above mentioned model; and finally, recommendations arising from the research results. The first research sub-aim is accomplished through selection of the Innovation Diffusion Theory (IDT) as the theoretical framework of this study after a review of different theories of technology adoption. The second research sub-aim is accomplished through the design of a conceptual model which is an adaptation of the relationship between the prior conditions construct and the knowledge/awareness construct of IDT. The prior conditions that were studied are students’ perceived exposure to career guidance and students’ perceived curriculum currency. These prior conditions were analysed as possible predictors of computing students’ technology awareness. The third sub-aim is accomplished by means of a survey of 116 computing students from the four universities of the KwaZulu-Natal province of South Africa, the results of which validated most of the relationships hypothesized by the above mentioned model. Having knowledge/awareness as the main variable of the current study can be seen as its main contribution in view of the fact that only two studies from the reviewed literature on IDT are examining the awareness/knowledge construct. The fourth sub-aim is accomplished by means of some recommendations, one of which is that gender and ethnicity be considered when curriculating computing courses both at the high school level and at the university level.
A SCORM compliant e-learning content prototype for the training of OBE mathematics educators in the context of developing countries
(2010) Piyose, Xolisa; Eyono Obono, Seraphin Desire
The main purpose of this study was to examine how e-learning can help resolve some of the most acute problems that are specific to the nature of the outcomes-based education (OBE) system in developing countries. This was accomplished by investigating the relevant literature on OBE and by designing an e-learning content prototype for the South African version of OBE, with the focus on the training of Mathematics and Mathematical Literacy educators. OBE is an education system centred on the theory of mastery of learning introduced by Bloom in the 1950s. It has been implemented worldwide in primary and secondary schools and also in tertiary institutions. Some studies have shown that OBE is problematic, and that both educators and learners are opposed to this system of education. Existing research also reports that the quality of education in OBE is very poor as compared to that of the traditional education system. This study was an attempt to identify the most acute problems experienced by educators and learners in the OBE context and to design a prototype for e-learning content that can be used in courses in an attempt to solve these problems. The research population of the perceptions survey consisted of Mathematics and Mathematical Literacy educators and learners from the 6 000 primary and secondary schools of the KwaZulu- Natal (KZN) province of South Africa. Eighteen schools formed part of the research sample, with an average of two schools per region (the KZN province is divided into nine regions). Both private and public schools were included in the study. Data for the study were collected from March 2007 to August 2007 in the form of a perceptions survey of 104 educators and 288 learners, yielding an average of six educators and sixteen learners for each randomly selected school. Results from the perceptions survey show that educators and learners do not understand OBE terminology. In addition, educators claim that they are not sufficiently trained for OBE. Research iii participants also report that schools’ basic infrastructure is unsatisfactory, and that their classrooms are overcrowded. Mathematics is perceived as the most difficult subject by both educators and learners. The survey also reveals that most public schools do not have computers and that neither educators nor learners have access to computers in their public libraries. A SCORM- (Sharable Content Object Reference Model) compliant e-learning course was developed in this study to address the most acute problems identified by the survey, based on the Software Engineering Unified Model. The designed e-course contains OBE terminology such as learning outcomes, OBE principles, assessment standards, assessment methods, national curriculum statement and learning fields. The e-learning course content also contains the Mathematics and Mathematical Literacy curriculum for grades 11 and 12. It was constructed using 16 documents extracted from the National Department of Education’s website: 7 documents under Further Education and Training, 4 under Teacher Guide, and 5 under General Education and Training. The evaluation of the e-learning content prototype was conducted through a survey among 36 educators from different primary and secondary schools of the Mnquma Municipality of the Eastern Cape province of South Africa. They were trained in the SCORM-compliant e-learning course content at the Walter Sisulu University’s Butterworth campus. The training took place from 10 to 13 November 2009. After the training, educators filled out a questionnaire on their perceptions of the effectiveness of the proposed e-learning content prototype with regard to the practice of OBE. Results from the SCORM e-course evaluation survey showed that the proposed SCORM software artefacts allow educators to have a better understanding of OBE terminology. The proposed software artefact is user-friendly and educators recommended its use not only for Mathematics but for all subjects.
A study of factors shaping learners' perceptions of ICT-based teaching and learning by applying personality and technology adoption theories on indigenous knowledge students
(2016) Ngcobo, Khumbuzile Mornica; Eyono Obono, Seraphin Desire
Existing literature indicates that the use of Information and Communication Technologies (ICTs) and the inclusion of Indigenous Knowledge Systems (IKSs) in the school curriculum have the potential to increase academic performance. However, formal education is still unable to integrate ICTs into the teaching and learning of school subjects, especially, those that are related to IKSs. This research therefore aims to construct a model of the factors shaping learners’ perceptions on the usefulness of ICTs for the teaching and learning of IKSs. This aim is sub-divided into four research objectives: (a) to identify appropriate technology diffusion theories for the investigation of the factors shaping learners’ perceptions on the usefulness of ICTs for the teaching and learning of IKSs, (b) to construct a theoretical model of the factors shaping learners’ perceptions on the usefulness of ICTs for the teaching and learning of IKSs, (c) to perform an empirical confirmation of the above announced theoretical model of the factors shaping the perceptions of learners on the usefulness of ICTs for the teaching and learning of IKSs, and (d) to suggest new ideas for future research on learners’ perceptions on the usefulness of ICTs for the teaching and learning of IKSs. A review of existing literature on eLearning adoption by students and learners was conducted in order to achieve objectives a, b, and d. As for objective c, it was achieved through the survey of 115 Hospitality studies learners from the ILembe and UMgungundlovu municipality districts in the KwaZulu-Natal (KZN) province of South Africa. The study’s findings can be summarized as follows: (a) The Technology Adoption Model (TAM) is the backbone of the model designed by this study on the factors affecting learners’ perceptions of the usefulness of ICTs for the teaching and learning of IKSs; (b) Learners’ perceived usefulness of ICTs is hypothetically affected by the following factors: demographics, computer self-efficacy, trust in ICTs, and level of conscientiousness, (c) All these factors were empirically confirmed through a survey conducted by the current study, except that the only validated demographics were : school location, cell phone access, class grade and preferred subject; (d) This research recommends further investigation on the factors affecting learners’ perceived usefulness of ICTs for the teaching and learning of IKSs, mainly because of the insufficient literature on this subject.
Using the technology adoption model for the modelling of teachers' technology awareness factors
(2016) Ntshakala, Tholokuhle Thobile; Eyono Obono, Seraphin Desire
Information and Communication Technologies (ICTs) are omnipresent in the world and that includes the worlds of sport, education and physical education (PE). However, there seems to be a scarcity of PE teachers who are well aware of the benefits of the use of ICTs in PE. The aim of this study is therefore to design a model of the factors affecting the perceived awareness of PE teachers of the benefits of the use of ICTs in PE. This aim is sub-divided into four research objectives: (a) to select relevant technology adoption theories for the design of a model of the factors affecting the perceived awareness of PE teachers of the benefits of the use of ICTs in PE; (b) to design a conceptual model of the factors affecting the perceived awareness of PE teachers of the benefits of the use of ICTs in PE; (c) to empirically test the above mentioned conceptual model; and, (d) to make appropriate recommendations from the knowledge of the factors affecting the perceived awareness of PE teachers of the benefits of the use of ICTs in PE. Objectives a, b, and d were accomplished through the review of existing literature on the factors affecting the adoption of e-learning by teachers. As for objective c, it was achieved through the survey of 73 teachers from Camperdown schools in the UMgungundlovu District Municipality of the KwaZulu-Natal province of South Africa. Here is a summary of how these objectives have been met in this study: (a) The Technology Adoption Model (TAM) serves as the theoretical model behind the choice of the research variables of this study; (b) This study hypothesizes that PE teachers’ perceived awareness of the benefits of the use of ICTs is affected by the following variables: demographics, performance expectancy, social influence, and computer attitude; (c) The survey conducted by this study confirms that PE teachers’ perceived awareness of the benefits of the use of ICTs is affected by their performance expectancy, and by three teachers’ demographics (computer usage, gender, and age group); (d) This study calls for more research on the factors affecting teachers’ awareness of the benefits of ICTs, since the study failed to find enough literature on this topic.
Validating cohesion metrics by mining open source software data with association rules
(2008) Singh, Pariksha; Eyono Obono, Seraphin Desire; Petkov, Doncho
Competitive pressure on the software industry encourages organizations to examine the effectiveness of their software development and evolutionary processes. Therefore it is important that software is measured in order to improve the quality. The question is not whether we should measure software but how it should be measured. Software measurement has been in existence for over three decades and it is still in the process of becoming a mature science. The many influences of new software development technologies have led to a diverse growth in software measurement technologies which have resulted in various definitions and validation techniques. An important aspect of software measurement is the measurement of the design, which nowadays often means the measurement of object oriented design. Chidamer and Kemerer (1994) designed a metric suite for object oriented design, which has provided a new foundation for metrics and acts as a starting point for further development of the software measurement science. This study documents theoretical object oriented cohesion metrics and calculates those metrics for classes extracted from a sample of open source software packages. For each open source software package, the following data is recorded: software size, age, domain, number of developers, number of bugs, support requests, feature requests, etc. The study then tests by means of association rules which theoretical cohesion metrics are validated hypothesis: that older software is more cohesive than younger software, bigger packages is less cohesive than smaller packages, and the smaller the software program the more maintainable it is. This study attempts to validate existing theoretical object oriented cohesion metrics by mining open source software data with association rules.
Web search engines as teaching and research resources : a perceptions survey of IT and CS staff from selected universities of the KwaZulu-Natal and Eastern Cape provinces of South Africa
(2011) Tamba, Paul A. Tamba; Eyono Obono, Seraphin Desire
This study examines the perceived effect of the following factors on web searching ability of academic staff in the computing discipline: demographic attributes such as gender, age group, position held by the academic staff, highest qualification, etc; lecturing experience, research experience, English language proficiency, and web searching experience. The research objectives are achieved using a Likert-scale based questionnaire for 61 academic staff from Information Technology and Computer Science departments from four Universities from the Kwazulu-Natal and Eastern Cape provinces of South Africa. Descriptive and inferential statistics were computed for data analysis from the questionnaire after performing data reliability and validity tests using factor analysis and Cronbach‟s coefficients methods on the PASW Statistics 18.0 (SPSS). Descriptive statistics revealed a majority of staff from IT as compared to staff in CS and, a majority of under qualified middle age male staff in junior positions with considerable years of lecturing experience but with little research experience. Inferential statistics show an association between web searching ability and demographic attributes such as academic qualifications, positions, and years of research experience, and also reveal a relationship between web searching ability and lecturing experience, and between web searching ability and English language ability. However, the association between position, English language ability, and searching ability was found to be the strongest of all. The novelty finding by this study is the effect of lecturing experience on web searching ability which has not been claimed by existing research reviewed. Ideas for future research include mentoring of academic staff by more experienced staff, training of novice web searchers, designing and using semantic search systems both in English and in local languages, publishing more web content in local languages, and triangulating various research strategies for the analysis of the usability of web search engines.
