As personal computers (PCs) and related ICTs become more and more omnipresent than ever before in institutions of education, teachers are faced with the challenge of having to teach in ICT rich environments. Some syllabuses increase this pressure by stipulating where ICT may be applied. While past research efforts have focused on presence of and/or effectiveness of ICTs on achieving various didactic goals, there is limited literature on the extent to which actual practice occurred naturally. It was the aim of this study to determine the extent to which Physics teachers and students used ICT in their usual teaching/learning ambience, referred to as natural settings in this study. Using activity theory as a theoretical lens, multiple case studies were chosen as a strategy using 10 schools, 15 Physics teachers, 20 A-level Physics students and 10 ICT teachers (computer specialists). Questionnaires, observations and informal and focus group interviews were used to elicit responses from students, teachers and computer specialists. It emerged from the case studies that despite the presence of apt ICT infrastructure in the schools and although the teachers had a positive attitude towards the use of ICT for teaching and learning of Physics, teachers were apathetic when it came to the actual use. Some of the reasons militating against use were lack of an ICT policy, school authority, and monopoly of computers enjoyed by computer studies teachers. However among students there were ‘early starters’ who used ICTs outside of school, a situation that tended to change the Physics learning environment. These findings led to a proposal for a post of Computer Specialist (CS) in the schools. The need for developing ICT policy at all levels namely national, Ministry of Education and the school was also proposed. Lastly staff development in the use ICT for Physics teachers was proposed as indispensable.

Mass marketing also referred to as traditional marketing, has been criticised for trying to appeal to everyone, without necessarily providing for customers’ needs and wants. Therefore, the traditional marketing mix has been deemed ineffectual in a highly competitive and ever-changing business world, especially in the banking sector. Changes in the marketing environment have led to the development of new concepts such as relationship marketing. The fundamental concept of relationship marketing involves maximising the longterm benefits for the bank and the customer, resulting in a series of transactions, which allow a long-term relationship to be established and maintained. In short, it is a marketing concept that revolves around building and maintaining a long-term link or bond with one’s customers. The Zimbabwean banking sector has been affected by the country`s political and economic turmoil over the past decade. The collapse of the economy has affected the banking sector and its relationship with clients. During the economic crisis, Zimbabwean banks were unable to meet the basic international requirements of the Basel Accord, and as such, no profits were made. Borrowers had problems repaying existing loans; and banks also became reluctant to lend more, as a liquidity problem in the financial system was prominent. In 2009, a new government was formed which introduced the multi-currency system and the economy went on a recovery path. Given the nature of the economy of Zimbabwe, relationship marketing becomes an indispensible marketing tool that banks can use. The main purpose of the research was to investigate the relevance of relationship marketing on the sustainability of Zimbabwean banks. Five independent variables (customer relations, product attributes, promotion and service delivery and information technology) were identified and were tested against one dependent variable (sustainability of banks). A positivist research paradigm approach was used to conduct the research. The approach uses the quantitative method of research to establish causal relationships. Null (Ho) and alternative hypotheses (Ha) were formulated in x order to test the relationship between variables. A five point Likert scale questionnaire was developed and administered in five major commercial banks in Harare, Zimbabwe namey; Banc ABC, Barclays bank, Commercial Banks of Zimbabwe, Stanbic Bank and Standard Chartered Bank. The five major banks were selected in terms of market capitalisation as well as total deposit share among other things. The empirical results revealed that five of the independent variables positively correlated with the dependent variable implying that they all have an impact on bank sustainability. However, the current situation (2011) in Zimbabwe shows that only two independent variables (product variables and service delivery) have any impact on bank sustainability. In other words, there was a relationship between product attributes and sustainability of banks. Additionally, there was a relationship between service delivery and sustainability of Zimbabwean banks. Conclusions sited that product attributes and service delivery, as variables of relationship marketing, if implemented desirably could salvage the lost confidence and contribute to bank sustainability in Zimbabwe. Therefore, recommendations given by the researcher extensively focused on the two variables that have a relationship with Zimbabwean banks’ sustainability; briefly on the three variables (customer relations, promotion and information technology) that had no relationship.

Climate change involves long-term change in the state of the climate. It is expected to have negative effects which include the increased frequency and intensity of climate extremes such as droughts, floods and storms. In addition, agricultural seasons and productivity are generally expected to be affected. This is likely to compound the problems that rural people in Africa face, especially the smallholder farmers. Thus, adaptation is of paramount importance. However, many factors limit the ability of farmers to adapt to climate change. This includes lack of information and knowledge about climate change. In rural areas an important source of information is agricultural extension; however, in some cases it is not effective and efficient. Information and Communication Technologies (ICTs) have been noted to play an important role in the dissemination of agricultural information, and recently, their potential in contributing to climate change awareness and adaptation has received increased attention. Therefore, the study aims to explore how ICTs contribute to climate change awareness and adaptation amongst communal farmers. The study was conducted in Seke and Murewa Rural Districts (herein Seke and Murewa) situated in Mashonaland East Province of Zimbabwe. The target population were communal farmers who are mainly dependent on agriculture (field crops, horticulture, fruit production, and livestock rearing). The two districts have climate associated with natural agro-ecological region II, with an average rainfall of 500-700 mm. The study used the mixed methods approach, which combined the quantitative method based on a survey of 300 farming households and the qualitative method based on key informant interviews. A multi-stage sampling approach was used for the survey. The data was collected in 2011. The Statistical Package for Social Scientists (SPSS) package was used for data entry and descriptive statistics, while Stata data analytical package was used for regression analysis. The first objective was to determine the level of access to ICTs by communal farmers in the two districts. Most of the respondents in both districts knew and owned the following ICTs namely, the radio, the mobile phone, and the television (TV). The main power sources for the ICTs were solar power, national grid electricity, and rechargeable batteries. Most of the respondents in both districts read newspapers, and church magazines. For almost all the print media in both districts, the main source of the media was through friends and relatives, buying and to some extent libraries and public places. The majority of respondents understood the language used in various ICTs, though some had difficulties in understanding the English language. The second objective was to assess how access to ICTs influenced climate change awareness amongst communal farmers in the two districts. The majority of respondents in both districts were generally found to be aware of climate change. Nevertheless, some of those who perceived themselves as being aware were actually not aware or had low awareness as revealed by the climate change awareness index. The respondents had limited understanding of the issues relating to causes and intervention measures to address climate change. From the regression analysis, the following factors were found to have a significant positive influence on climate change awareness: access to mobile phone, access to radio, access to newspapers, access to agricultural extension, participation in developmental and farmer organisations, having talked about climate change, education level, and age of the respondent. One variable namely position of authority had a significant negative relationship. The third objective of the study was to investigate the contribution of ICTs in climate change adaptation amongst the communal farmers. This objective was fulfilled by mainly concentrating on assessing how farmers accessed forecasting and early warning information. Up to two-thirds of the respondents indicated that they did not have access to timely early warning information on droughts and violent storms. In addition, around half of the respondents indicated that they were not getting information on the likely rainfall amount and distribution in the coming season. Respondents ranked deciding the planting dates and the choice of crop varieties as the most important farm decision-making activities that were influenced by forecasting information. Some of the channels through which farmers accessed early warning and weather information were radio, extension, direct enquiry, TV, other farmers, newspapers, mobile phone, and farming magazines. This study showed that both old and new ICTs are important in information dissemination and capacity building for climate change adaptation and awareness. In order for rural people to benefit from various applications and capabilities of ICTs, in particular, mobile phone applications, there is need to improve telecommunications and broadcasting infrastructure. Agricultural extension workers who are an important source of information in rural areas, had less knowledge on climate change issues hence the need to incorporate such issues into their training. Initiatives to promote climate change awareness and adaptation should provide platforms for diverse stakeholders to share and exchange information and knowledge on climate change. There is need to improve the reliability of weather forecasting information as well as training farmers on how to interpret the information. Most importantly, complimentary agricultural information, inputs, and technologies should be available and accessible to the farmers. / Environmental Sciences / D.

The purpose of this study was to explore the practice of quality control in the onscreen marking (OSM) environment of Biology (5008) examinations between 2013 and 2017. Examination marking is gradually being migrating from paper-based marking (PBM) to OSM in a bid to improve the efficiency and quality of marking. The Zimbabwe School Examinations Council (ZIMSEC) introduced OSM for some O Level subjects in June 2012, in a context characterised by a persistent economic crisis, patchy internet coverage, erratic power supplies and low digital literacy, among other challenges. The Council encountered some difficulties related to quality control, which triggered this qualitative instrumental single case study that was informed by the ontology, epistemology, methods and axiology of the constructivist philosophy. Data were collected through face-to-face and focus group interviews on the WhatsApp platform with 4 subject managers, 11 senior markers and 18 normal markers, and through document review. The findings of the study suggest that the quality of marking was influenced by the context in which the examinations were marked. The socio-political climate that prevailed in Zimbabwe impacted on the technological infrastructure for the OSM and the digital literacy of the examination personnel. The capacity of the examiners to work in the OSM environment was influenced by knowledge and skills transfer from training and standardisation to the live marking. The quality of marking was monitored by the seeds approach to script moderation, automatically generated reports and audit trails, and escalation of problem scripts. It was also influenced by the structure of the question papers, cognitive demands of the questions and mark schemes on the examiners, spaces provided for candidates’ responses and mark scheme features such as language and marks to marking points ratio. The assessment framework provided by the syllabus guided the design and marking of Biology examinations. From these findings, a framework that could guide the practice of quality control in the OSM environment was formulated. OSM technology could enhance the quality of marking Biology examinations, thereby eliminating challenges associated with PBM. Some of the opportunities were, however, reduced by the challenges encountered during the OSM of the examinations. It is recommended that ZIMSEC put in place policies and procedures that could guide specific quality control activities in the OSM environment and establish computer centres in the provincial capital towns. The Council could also consider benchmarking examiner recruitment, training and standardisation procedures with international examination authorities. / Tsvakurudzo ino yanga yakananga kuvandudza nharaunda yemakwenyero ebvunzo kubudikidza nemichina pachidzidzo cheBhayaroji, 5008 pakati pemakore a2013-2017.

Abstracts in English, Zulu and Setswana / This study investigated the feasibility of using WhatsApp Messenger as a tool to enhance the professional identity and inquiry-based pedagogy through the professional development of university chemistry teachers. The epistemological interpretive paradigm was used to guide the study. The study assumed a naturalistic, exploratory investigation. The qualitative research methodology was used to conduct the study. Nine university teachers were purposively sampled from three universities (three teachers from each university) for the study. Data were collected through semi-structured interviews, participant observations, and focus group discussions. Data analysis was completed using the thematic networks analysis. Ethics considerations were observed by not disclosing personal information of the participants or information about the universities where they represented. This study was guided by four theoretical underpinnings: the connectivism theory, the transformative learning theory, the expectancy-value theory, and the dual systems theory. The primary research question guiding this study was: How does the professional identity of university chemistry teachers develop as they learn IBP through WhatsApp Messenger? A two-pronged approach was used in the research: (1) comparing the professional identity of the teachers before and after the course, and (2) observing and describing the professional identity process as the teachers undertook the course. The results from the interviews conducted before the teachers undertook the WhatsApp Messenger-based IBP course showed that most teachers had a negative professional identity. They had become teachers for a variety of reasons, but they did not consider themselves teachers and believed they would leave university teaching if opportunities arose in the industry. They had no formal qualifications in pedagogy, and they did not believe that such knowledge was necessary. The majority of these teachers used teacher-centred approaches. Results from participant observations during the WhatsApp Messenger-based IBP course showed that the course slowly imparted to the teachers the norms associated with not only IBP, but other teaching approaches as well. WhatsApp Messenger provided a flexible online platform where the teachers interacted and exchanged ideas without the need to meet in a physical space. The results from the interviews conducted after the teachers participated in the WhatsApp Messenger-based IBP course showed that the participants' professional identity had changed positively. They now recognised the importance of pedagogy in teaching, they positively identified with the teaching profession, and some were considering acquiring formal qualifications in pedagogy. / Lolu cwaningo beluphenya ithuba lokusetshenziswa kwangempela kwe-WhatsApp Messenger njengethuluzi lokuqinisa isithombe sesisebenzi kanye nohlelo lokufundisa olwencike phezu kophenyo lothisha besifundo seKhemistri (chemistry) enyuvesi, ngohlelo lokuthuthukisa abasebenzi. Uhlelo lwepharadayimu echazayo ye-ephistemoloji lwasetshenziswa ukuhlahla indlela yesifundo, okuyindlela enqume ukulandela indlela yemvelo, ephenyayo. Umethodoloji wocwaningo olwencike kuKhwalithi (Qualitative) lusetshenzisiwe ukwenza ucwaningo, ndawonye nothisha basemanyuvesi ayisishiyagalolunye abakhethwe ngenhloso kumanyuvesi amathathu (abathathu kwinyuvesi eyodwa). Idatha yaqoqwa ngokusebenzisa izinhlolovo ezimbaxambili (semi-structured interviews), ngokubheka izenzo zomdlalindima (participant observation) kanye nezingxoxo zeqembu eliqondiwe (focus group discussions), kanti ukuhlaziywa kwedatha kwenziwa kwaqedwa ngokusebenzisa uhlelo lokuhlaziya oluwuthungelelwano lwendikimba (thematic network analysis). Kubonakele ukulandelwa komgomo wokuziphatha ngokungadaluli ulwazi lomuntu ongumdlalindima noma ulwazi olumayelana namanyuvesi ababewameleyo. Ucwaningo beluholwa yizinhlaka ezine zethiyori: i-connectivism theory, i-transformative learning theory, i-expectancy-value theory kanye nama-dual systems theory. Umbuzo wokuqala wezocwaningo ohola ucwaningo bewuthi: Ngabe isithombe sobizo lobuthishela wekhemistri enyuvesi sithuthukiswa kanjani ngesikhathi befunda uhlelo lwemfundo eyencike ekuphenyeni (inquiry-based pedagogy (IBP) ngokusebenzisa i-WhatsApp Messenger? Indlela embaxambili iye yasetshenziswa: 1) ukuqhathanisa isithombe sobizo lobuthishela ngaphambi nangemuva kwesifundo,, kanye no-2) baqhathanisa isithombe sobizo lobuthishela sothisha ngaphambi nangemuva kwesifundo, kanye no 2) babheke futhi bachaza uhlelo lwezimpawu zokwakha isithombe sobizo lobuthishela njengoba othisha baye badlala indima kulesi sifundo. Imiphumela evela kwizinhlolovo ezenziwe ngaphambi kokuba othisha bahambele isifundo se-WhatsApp Messenger-based IBP, ikhombise ukuthi iningi lothisha libe nesithombe sobizo esibi. Baye bafundela ubuthishela ngezizathu ezahlukahlukile, kodwa abakaze bazibona bangothisha futhi baye bacabanga ukuyeka inyuvesi uma ngabe kuvela amathuba kwimboni. Abakaze babe neziqu zokufundisa, kanti abazange bakholwe ukuthi ulwazi olunjalo kwakunesidingo sokuba nalo, kanti iningi lothisha lwalandela indlela izindlela ezencike kuthisha. Imiphumela evela ekubukeni izenzo zothisha ngesikhathi sesifundo se-IBP ikhombise ukuthi isifundo kancane kancane sinikeze othisha izimfundiso ezithile, kanti futhi nezinye izindlela zokufundisa. Uhlelo lwe-WhatsApp Messenger lunikeze inkundla ye- inthanethi engenamngcele lapho othisha bebahlangana futhi baphakelane ngemibono nhlangothi zombili ngaphandle kwesidingo sokuhlangana endaweni ephathekayo. Ngemuva kwesifundo se-IBP abadlalindima baye babika ukuthi babone izithombe zobizo lwabo zizinhle kakhulu. Manje sebeyakwazi ukubaluleka kwendlela yephedagogi ekufundiseni, bazibona behambisane kahle kakhulu nobizo lobuthishela. Kanti abanye baze bacabanga ukuthola ezinye iziqu ezisemthethweni zobizo lobuthisha. / Thuto e, e dirile dipatlisiso tsa kgonagalo tsa go dirisa WhattsApp Messenger jaaka sediriso sa go tlotlomatsa tlhaolo ya borutegi le potsiso theo ya thuto ya sekolo ya barutabana ba Yunibesithi ba thuto ya khemise, ka tlhabololo ya borutegi.
