The Association between Long-Term DDT or DDE Exposures and an Altered Sperm Epigenome-a Cross-Sectional Study of Greenlandic Inuit and South African VhaVenda Men.

The organochlorine dichlorodiphenyltrichloroethane (DDT) is banned worldwide owing to its negative health effects. It is exceptionally used as an insecticide for malaria control. Exposure occurs in regions where DDT is applied, as well as in the Arctic, where its endocrine disrupting metabolite, -dichlorodiphenyldichloroethylene (-DDE) accumulates in marine mammals and fish. DDT and -DDE exposures are linked to birth defects, infertility, cancer, and neurodevelopmental delays. Of particular concern is the potential of DDT use to impact the health of generations to come via the heritable sperm epigenome. The objective of this study was to assess the sperm epigenome in relation to -DDE serum levels between geographically diverse populations. In the Limpopo Province of South Africa, we recruited 247 VhaVenda South African men and selected 50 paired blood serum and semen samples, and 47 Greenlandic Inuit blood and semen paired samples were selected from a total of 193 samples from the biobank of the INUENDO cohort, an EU Fifth Framework Programme Research and Development project. Sample selection was based on obtaining a range of -DDE serum levels (). We assessed the sperm epigenome in relation to serum -DDE levels using MethylC-Capture-sequencing (MCC-seq) and chromatin immunoprecipitation followed by sequencing (ChIP-seq). We identified genomic regions with altered DNA methylation (DNAme) and differential enrichment of histone H3 lysine 4 trimethylation (H3K4me3) in sperm. Differences in DNAme and H3K4me3 enrichment were identified at transposable elements and regulatory regions involved in fertility, disease, development, and neurofunction. A subset of regions with sperm DNAme and H3K4me3 that differed between exposure groups was predicted to persist in the preimplantation embryo and to be associated with embryonic gene expression. These findings suggest that DDT and -DDE exposure impacts the sperm epigenome in a dose-response-like manner and may negatively impact the health of future generations through epigenetic mechanisms. Confounding factors, such as other environmental exposures, genetic diversity, and selection bias, cannot be ruled out. https://doi.org/10.1289/EHP12013.

Qualitative Study on the Voices of Adolescents Living with Perinatally Acquired HIV in Selected Clinics in the Limpopo Province of South Africa.

The disclosure of HIV status among adolescents living with perinatally acquired HIV (APHIV) has become one of the core challenges in the management of APHIV. Disclosure is a challenge that undermines positive advances and achievements in HIV management. There is limited literature on the voices of APHIV on disclosure of their status. This study aims to explore the current disclosure process and how it affects APHIV. A qualitative exploratory design was employed to conduct one-on-one in-depth interviews using a semi-structured interview guide. Purposive sampling was used to sample 21 APHIV in 16 selected health facilities in the Vhembe district of Limpopo Province, South Africa. Data were analyzed using Tesch's qualitative data method. The findings of this study reflect the gaps in the current disclosure process and guidelines while acknowledging the importance of disclosure to APHIV. A notable finding in this study is that most APHIV, especially those in early adolescence, did not want to know their HIV status due to the stigma attached to an HIV-positive diagnosis. This study suggests that proper training and support of parents and/or guardians in the disclosure process are needed, as they are the primary caregivers of APHIV. The disclosure of HIV status must be a comprehensive part of the management and care of HIV for APHIV. Furthermore, dedicated support programs should be developed and implemented to improve their lives post-disclosure.

Analysis of Climate Variability and Its Implications on Rangelands in the Limpopo Province

In recent decades, southern Africa has experienced a shift towards hotter and drier climate conditions, affecting vital sectors like agriculture, health, water, and energy. Scientific research has shown that the combination of high temperatures and unreliable rainfall can have detrimental effects on agricultural production. Thus, this study focused on assessing climate variability, with implications on rangelands in the Limpopo Province of South Africa over 38 years. Historical climate data from 15 stations, including rainfall and minimum and maximum temperatures from 1980 to 2018, were analysed. To achieve the main objective, various statistics including mean, standard deviation, and coefficient of variation (CV) were computed for all variables across four seasons. The results highlighted significant variability in rainfall, with Musina (71.2%) and Tshiombo (88.3%) stations displaying the highest variability during the September-to-April season. Both minimum and maximum temperatures displayed low variability. The Mann–Kendall test revealed both increasing and decreasing trends in minimum temperatures and rainfall across different stations. Notably, there was a significant increase in maximum temperatures. This study provides valuable climate information for decision makers, aiding in the planning and management of agricultural activities, particularly in understanding how climate variations affect forage availability in rangelands.

Solving quadratic equations by completing the square: Applying Newman’s Error Analysis Model to analyse Grade 11 errors

Error analysis is an instructional strategy that can assist teachers to identify learners’ areas of weakness in mathematics and that can point to remediation of those errors. This article explores the errors learners exhibit when solving quadratic equations by completing the square using Newman’s Error Analysis Model. A research study explored the errors learners exhibit when solving quadratic equations by completing the square. Newman’s Error Analysis Model provided the analytic framework for the qualitative approach that was used to explore those errors. A diagnostic test with five test items was administered to 35 learners in one secondary school in Limpopo province of South Africa. Subsequently, 12 learners whose scripts featured common mistakes were identified; these learners participated in a semi-structured interview to diagnose the errors. The findings revealed that learners commit comprehension, transformation and process errors. The findings suggest that if the errors that learners make are exposed and made explicit, the errors can be remediated and thereby enhance understanding and learning. The findings of this study indicate that for teachers to understand the types of errors learners commit when solving quadratic equations by completing the square it is vital for them (errors) to be addressed. Mathematics teachers should also consider diagnosing why learners commit those errors, as they would know the strategies to be employed to teach this topic and subsequent topics.Contribution: The findings of this article add value to the current literature by providing empirical knowledge on learner challenges when solving quadratic equations by completing the square. This study provides opportunities for mathematics teachers to focus more on the strategies that would assist learners to understand this topic.

A Review of Rural Communities’ Vulnerability to Climate Change: The Case of Limpopo Province in South Africa

Climate change threatens the livelihood of rural communities that depend on climate-sensitive resources. The risks and consequences of climate change, to which rural areas are especially susceptible, are discussed in this review. The review summarizes previous studies on rural communities' susceptibility to the impacts of changing climatic conditions. Previous studies on climate change in South Africa's Limpopo Province provide the information used in this review. The findings indicate that rural communities are vulnerable to rising temperatures and unpredictable precipitation. The communities are exposed to higher temperatures, less rainfall, and intermittent drought. Subsistence agricultural and livestock production and water supplies are two examples of climate-dependent livelihood resources vulnerable to weather variability and change. These resulted in food insecurity and water scarcity in many rural areas. This review helps fill a gap in understanding the importance of assessing the vulnerability of rural communities with climate-dependent livelihood resources. The study recommends detailed community-based adaptation measures to counteract the detrimental effects of climatic stresses on people's means of subsistence. Adaptation policies to climate change could be strengthened by incorporating indigenous adaptation techniques and community voices into response efforts.

Using Vhavenda Traditional Entertainment to Curb HIV Spread in the Rural South African District

Purpose. This study explored the use of traditional entertainment as a means of curbing human immunodeficiency virus (HIV) spread in the Vhembe district of South Africa. Engaging in cultural dances like tshikona, tshifasi, tshigombela, malende, davha, and musangwe keeps the youth grounded, making it less likely that they will engage in unprotected sexual intercourse. Methods. This qualitative study utilized an ethnographic design. The study was conducted in rural villages in Vhembe district, Limpopo province in South Africa. Eighteen participants consisted of Vhavenda traditional leaders and chiefs who met the selection criteria were purposively selected to participate in the study. The sample size was determined by data saturation. Semistructured face-to-face interviews were used to collect data, guided by an interview guide. Four observations were done concurrently with the interviews. Interviews were audio-recorded, and field notes were taken. Ethnographic content analysis was used to analyze the data collected. Results. The results indicate that Vhavenda traditional entertainments like tshigombela and tshikona can be used in reducing and managing the spread of HIV, whereas malende, tshifasi, davha, and musangwe have the potential to spread and increase incidences of HIV. Conclusion. The traditional entertainment such as tshigombela and tshikona can be utilized as they instill good morals. Malende, tshifasi, davha, and musangwe can be repatterned and modified. Traditional entertainments, if properly utilized, can add to the strategies of reducing the new incidences of HIV.

Teachers' Lived Experiences of Workplace Violence and Harassment Committed by Learners from Selected High Schools in Limpopo Province, South Africa.

Despite several studies on learner-to-teacher workplace violence and harassment, the problem persists in some South African schools. Learner-to-teacher violence and harassment is a form of workplace violence and harassment, as schools are workplaces for teachers. Learner-to-teacher violence and harassment is therefore an important occupational health and safety issue for teachers. Employers are obliged to provide a safe working environment for teachers to enable quality teaching and learning in schools. The purpose of this interpretative phenomenological study was to explore and describe the lived experiences of high school teachers who have been targets of workplace violence and harassment perpetrated by learners at selected schools in Limpopo Province of South Africa. Many teachers were willing to share their lived experiences but, due to data saturation, only eleven participated after being selected through purposive sampling from seven high schools under a chosen sub-district. The research ethics of voluntary participation, informed consent, ethical clearance, and gatekeeper permission were observed. Data were collected through semi-structured interviews using an interview guide. The interviews were audio-taped, and field notes were also taken. Voice recordings were transcribed verbatim and analysed using interpretative phenomenological analysis into themes and sub-themes. The findings were confirmed by an independent coder to achieve trustworthiness. Teachers experienced physical workplace violence and harassment, verbal workplace violence and harassment, and nonverbal workplace violence and harassment from learners. Learner-to-teacher workplace violence and harassment affects teachers emotionally, and in turn, affects the quality of teaching and learning in schools. Some teachers propose the involvement of a community policing forum, the strengthening of schools' governing bodies, and reducing overcrowding in classrooms as possible solutions to deal with learner-to-teacher workplace violence and harassment.

Midwives’ Views Regarding Tuberculosis Screening amongst HIV/AIDS Positive Pregnant Women South Africa

Tuberculosis (TB) infections is classified as one of the non-pregnancy related infections (NPRI) which cause maternal mortality. Therefore, it was important for the researcher to explore the challenges faced by midwives regarding TB screening as it is the most leading complication in human immunodeficiency virus (HIV) infected pregnant women. To that effect, several strategies for TB screening during pregnancy have been introduced and implemented thus far. Screening of TB during antenatal care helps to enhance early detection, exclusion and treatment of the infection in pregnant women who are HIV positive. The study used qualitative descriptive research design. The population included all midwives aged 30 to 48 years, who were working at primary health (PHC) clinics in Kganya local area, Capricorn District, Limpopo Province in South Africa. Nonprobability purposive sampling technique was employed to select ten midwives. Data were collected through in-depth individual semi -structured interviews with ten midwives. Data analysis was accomplished, using the manual thematic analysis according to Tesch’s method of data analysis. Finally the main themes were extracted. Two themes emerged from the study, namely: Challenges regarding TB screening; Measures that can enhance TB screening. It is important that the department of health should pay attention to challenges faced by midwives to ensure adequate TB screening amongst HIV positive pregnant women. Capacitating both midwives and the community with knowledge regarding TB screening during pregnancy can be beneficial to the health of the pregnant women and their unborn babies.

Undergraduate Students’ Experiences with Electronic Learning Platforms During the Covid 19 Pandemic at a Rural-Based Tertiary Institution in South Africa

The Covid-19 pandemic necessitated a transformative shift in the South African education sector, compelling universities to adopt electronic learning platforms (E-LPs) as the primary mode of delivering lectures during the pandemic. However, there is a dearth of systematic literature documenting the implications of migration to this electronic based model for undergraduate teaching and learning in South African rural-based universities. Addressing this research gap, this qualitative study drew on transitional distance theory (TDT) to identify the challenges associated with electronic learning (e-learning). The study also examined the implications of these challenges for teaching and learning, based on experiences of 30 purposefully selected undergraduate students at the University of Venda, in the rural Limpopo province of South Africa. A thematic narrative analysis of the students’ experiences shows three major challenges as encapsulating the use of E LPs: practical unpreparedness and lack of skills needed for online learning; complicated domestic obligations; and inefficient interactions with lecturers and peers, which were limited by lack of physical contact. These findings add to the growing body of literature on the impact of Covid-19 on learning at institutions of higher learning in South Africa. The findings have implications for discussions on gender inequality in the domestic sphere in South Africa, as well as the material disparities between traditionally White universities and rural-based universities in South Africa. Based on these findings, it is recommended that rural-based tertiary institutions in South Africa implement effective strategies to enhance students’ computer skills and familiarize them with E LPs at the early stages of their tertiary education.

Traditional ecological knowledge and practices for ecosystem conservation and management: the case of savanna ecosystem services in Limpopo, South Africa

ABSTRACT Traditional ecological knowledge (TEK) aids ecosystem conservation and management. While recognising the importance of Western science and knowledge, we argue that TEK practices are not appreciated resulting in continued and accelerated degradation of ecosystem services. This is prevalent among rural communities who are disadvantaged as their livelihoods depend on these ecosystem services. Taking the Capricorn District of Limpopo Province in South Africa as a case study, we explored the TEK practices employed to conserve and manage savanna ecosystem services. Employing the socio-ecological analysis (SEA) theory, we examined the perception and value of savanna ecosystem services. Data were initially collected from interviews with a professional biodiversity expert, an academic biodiversity expert, and a professional archaeologist and cultural expert (n = 4). In phase two, interviews were conducted with tribal representatives, traditional leaders, and community members (n = 43) in the four villages of Ga-Dikgale, Ga-Matlala, Moletlane and Ga-Malebogo across Capricorn District Municipality. Field observations were also undertaken. The findings highlighted the interrelated forms of sociocultural practices for the conservation and management of savanna ecosystem services, including norms, taboos, myths, rules, and cultural lifestyles. There were age differences in valuing and using TEK where younger people perceived TEK as backward. They relied on Western scientific knowledge, which they lauded as contemporary and not in opposition with their religious values. In conclusion, TEK continued to provide best practices for ecosystem conservation and management. This was identified by the respect and attention from the community who were aware of TEK even if they did not practice the processes. However, TEK is under threat as rural communities become more urbanized.

Strategies to enhance sexual health education for prevention of teenage pregnancy in Vhembe District, Limpopo Province: different stakeholder’s perspectives, a co-operative Inquiry qualitative protocol paper

BackgroundSouth Africa is reporting higher rates of adolescent pregnancy as compared to other countries. There are different types of interventions that are in place to address teenage pregnancy. However, these interventions were developed using top-down strategy without the inclusion of different stakeholders and adolescents which makes it hard to implement those interventions particularly in countries like South Africa. Hence, this study aimed to develop strategies to enhance sexual health education for prevention of teenage pregnancy in Vhembe District, Limpopo Province of South Africa.MethodsThe research design of this study will be Co-operative Inquiry.The study will take place in Vhembe District in Limpopo province of South Africa through collaborating with a Non-governmental Organisation (NGO). The study population will be the teenagers and all the different stakeholders caring for teenagers in their areas of specialization. Purposive sampling will be used to sample the targeted participants of the study. The data collection method will be done in phases and focus group discussions will be used to collect data. Content analysis will be used to analyse data.DiscussionThis study will add to the body of knowledge regarding the strategies that maybe used to enhance sexual health education for prevention of teenage pregnancy.

Groundwater recharge influenced by ephemeral river flow and land use in the semiarid Limpopo Province of South Africa

Determining the sustainability of groundwater use in drylands with high climate variability is complex. Central to this determination is an understanding of groundwater recharge and associated processes and controls. Groundwater recharge in drylands can occur by diffuse and focused recharge (focused recharge being associated with intense episodic rainfall events and ephemeral river flow, predicted to increase and intensify with climate change). This study evaluated the relative significance and dominant controls on these two recharge processes. Ten groundwater hydrographs with multidecadal observations were collated from the Limpopo Province, South Africa, based on their proximity to river channels and rain gauges, representing diversity in local climate, landscape, vegetation, and hydrogeological conditions. The hydrographs showed that groundwater-level rises are sensitive to rainfall intensity during the rainy season, with generally larger increases after years with large episodic rainfall events, which disproportionately contribute to groundwater replenishment. Recharge processes and annual recharge volumes were quantified using the water-table fluctuation method and the numerical model HYDRUS-1D. This allowed for the inference of additional recharge contributions from focused recharge in proximity to ephemeral rivers, up to a factor of five relative to diffuse recharge. The analysis revealed synchronicity and linear correlation between annual river discharge and recharge close to the river, substantiating the importance of focused recharge close to the river network. The study showed that recharge in drylands is subject to large spatial and temporal variation and that consideration of focused and episodic recharge is critically important for managing groundwater resources at various scales in these regions.

Analysis of COVID-19 cases and comorbidities using machine learning algorithms: A case study of the Limpopo Province, South Africa

This study examined the biological, social, and clinical risk factors for mortality in coronavirus of the year 2019 (COVID-19) hospitalised patients. The population of the study is prone to COVID-19, thus understanding the most common traits and comorbidities of people who were affected is crucial in reducing its consequences. In this study, four supervised machine learning algorithms were implemented and compared to predict the mortality rate based on the explanatory variables across the five districts of Limpopo Province in South Africa. The data was obtained from Limpopo Department of Health. Prediction about the chances of dying from COVID-19 disease was made using logistic regression, random forest, support vector machine, and decision tree algorithms on the dataset of 20,592 records with twenty-one attributes. Due to the imbalanced nature of the data, Random Over-Sampling Examples (ROSE) were employed to balance our data for more accurate classification effectively. The ROSE package provides functions to deal with binary classification problems in the presence of imbalanced classes. We used 70% of the data for training, while 30% was selected for testing the predictive algorithms. A technique called Step Akaike's Information Criterion (StepAIC) was deployed to reduce the insignificant variables from the full model of the logistic regression. According to the findings of the study, among the four algorithms tested, random forest had the highest recall rate for predicting mortality at roughly 79 percent compared to the other three algorithms. Accordingly, we conclude that random forest algorithm is appropriate for predicting the chances of patients dying from COVID-19 based on the attributes of the five districts of Limpopo Province. In terms of the features and their importance, a function called Variable Importance (VarImp) was used to check which of the attributes have predictive power on the outcome variable (discharged status). The findings revealed that age, ever ventilated, ever oxygenated, intensive ward upon admission, Waterberg district, and private facility type were among the risk factors that could be selected for the logistic regression model to predict mortality in hospitalised patients. This implies that special attention should be given to these identified variables. The random forest model is adequate to establish these factors since the findings reveal that a fairly considerable percentage of explained variation would correctly classify 79% of the cases. The novelty of conducting research on the analysis of COVID-19 cases and comorbidities using machine learning algorithms lies in the potential to uncover new insights and patterns that might not be immediately apparent through traditional statistical methods. Machine learning algorithms can quickly and accurately analyze large datasets and identify complex relationships between variables, which could provide valuable information for public health officials and policymakers.

The impact of gender-based violence on girls in the selected secondary schools in Limpopo, South Africa

The crucial mandate for any state is that learners attain their education in a safe learning environment. Learners’ access to a high-quality, inclusive, equitable education, and their capacity are jeopardised by the pervasive gender-based violence in and around schools. This paper aims to investigate the impact of gender-based violence on girls in the selected secondary schools in Limpopo Province of South Africa. From the qualitative standpoint, coupled with the case study research design, this study used a purposive sample to select 15 (n = 15) participants. Data were collected through literature reviews and the application of semi-structured Key Informant Interviews and analysed using Thematic Analysis. The findings of this study include (i) low school performance, (ii) learners who are dropping out, (iii) learners’ inability to exercise their human rights and their right to an education, (iv) lack of a well-resourced and strong criminal justice system, and (v) an intervention team to address the impact of gender-based violence on girls. This study concludes that gender-based violence should be taught as a subject in schools to address the persistent issue in South Africa for learners to understand abuse and violation in the future. This paper recommends that all stakeholders in our society—civil, social workers, and law enforcement authorities—collaborate more closely than they currently do to end gender-based violence against schoolgirls.

Challenges faced by curriculum advisors when offering curriculum support to schools in rural South Africa

Many stakeholders have severe concerns about providing curriculum support to schools. South African districts have minimal authority beyond planning and focusing objectives on district settings, but they are in charge of implementing all areas of educational operations, including curriculum, funds, and resources. Curriculum support has come under scathing criticism from teachers and principals who describe it as difficult and unsustainable. From a qualitative standpoint, coupled with the case study research design, this study used a purposive sample to select 15 (n = 15) participants. Data were collected through literature reviews and the application of semi-structured Key Informant Interviews and analysed using Thematic Analysis. The results of the study include understaffing of curriculum advisors, heavy workloads, incompetence, a lack of skill and pedagogical training that are requisite for the task, and a time constraint to handle curriculum challenges. This paper aims to investigate challenges faced by curriculum advisors when offering curriculum support to schools in the Waterberg District in the Limpopo Province of South Africa. This study concludes that adequate operational resources should be made available since they can improve everyone's access to high-quality teaching and learning resources. It is recommended that adequate funding be made available to address the district's financial issues so that curriculum advisors can easily provide curriculum support.

Household socio-economic determinants of food security in Limpopo Province of South Africa: a cross sectional survey

BackgroundDespite the strong commitment at both national and international levels to eradicate hunger and achieve household food security, by 2030 food insecurity remains a public health problem. South Africa is amongst the countries with the highest rate of income inequality in the world and extremely high levels of absolute poverty. The Gini coefficient in South Africa is estimated at 0.68 Although South Africa may be food secure at a national level, large numbers of households within the country are food insecure approximately 52% of the rural households in Limpopo Province of South Africa were considered severely food insecure. It has been noted that the majority of households in South African informal settlements and rural areas were moderately or severely food insecure due to lack of access to food which was directly related to income. Rural areas have assets that can be explored to support households. The adult population above 18 years in South Africa make up 78% of the 5.9 million population with about 40% living in rural areas, this study explored household food insecurity in adults in rural environments. The current study aimed to explore the socioeconomic and dietary determinants of household food insecurity among the adult population in the Limpopo Province.MethodsA cross-sectional survey design was used, and data were collected using a validated pre-tested questionnaire. The participants were recruited from households in Limpopo province. Multiple linear regression was computed to explore the influence of socioeconomic and dietary practices on food insecurity.ResultsThe study included 699 randomly selected participants of which the majority earned a monthly income ≤ 3000 ZAR, and 31.8% experiencing hunger in the past 30 days at the time of study. The dietary practices of the participants were found to be associated with household food insecurity. The study found that large family size, being female in South Africa, low household income and low rate of regular breakfast intake were significant determinants of household food insecurity (p < 0.05).ConclusionIn summary, most of the households were poor and approximately one-third were food insecure. The implementation of sustainable employment policies, and food-based approaches and targeting rural household food production could significantly reduce food insecurity in the rural area.

Characterisation and pathogenicity of Verticillium dahliae isolates associated with Verticillium wilt of tomato in the Limpopo Province of South Africa

In the Limpopo Province of South Africa, the sustainable production of tomatoes is threatened by a soilborne disease known as Verticillium wilt. Limited information is available regarding the Verticillium species involved, their genetic diversity and aggressiveness. Therefore, a pathogen survey was conducted in the three major tomato production regions in Limpopo (six fields in the Lowveld and two fields each in the Highveld and Soutpansberg). Verticillium dahliae was identified as the only Verticillium species associated with Verticillium wilt of tomatoes. Conventional vegetative compatibility group (VCG) testing identified 38 isolates as VCG 4B and two isolates as VCG 2B. Pathotype-genotype specific PCR analysis indicated that all the isolates belonged to the non-defoliating pathotype, specifically genotype C. These characteristics allowed for the classification of almost all the isolates from the Lowveld, Highveld and Soutpansberg regions into clonal lineage 4B (38 isolates). The exception was for two isolates from the Lowveld that belonged to lineage 2B824. Based on a race-specific PCR analysis, all 40 isolates belonged to race 2. Sequencing of the race-specific PCR amplicon revealed the presence of two haplotypes namely I and II. Evaluation of seven inoculation methods (agar plug, millet, node-inoculation, root-dip, sand-bran, soil-drench and toothpick methods) using three isolates showed that the root-dip method was the only method that consistently identified all the isolates as pathogenic based on disease severity as well as an increase in plant height. Assessment of the aggressiveness of the 40 characterised V. dahliae isolates showed that the isolates varied in aggressiveness to the cv. Floradade.

The Impacts of Peri-Urban Expansion on Municipal and Ecosystem Services: Experiences from Makhado Biaba Town, South Africa

The sub-Saharan cities are growing and changing due to immigration and modernization. One of the consequences of the current urbanization is that an increasing number of families residing in peri-urban areas of small rural towns lack access to basic municipal and ecosystem services. The purpose of the paper is to demonstrate the impacts of peri-urban expansion on municipal services provided by the governments and on ecosystems services through a case study of a small rural town called Makhado Biaba in Limpopo Province of South Africa. Makhado Biaba has been experiencing incessant rapid physical expansion over the years. Such spatial expansion into the peri-urban zone impacts the provision of municipal services such as water, electricity, sewerage, and refuse collection. In 2020, an exploratory mixed-methods study of some anthropocentric and ecosystem changes in Makhado Biaba Local Municipality in northeast South Africa was executed. Land use was mapped for the time period of 1990–2020, data were gathered through a household questionnaire in six villages, and interviews were held with municipal officials. Among others, the study showed that several municipal services are available in the peri-urban villages of Makhado Biaba Town despite the distant locations outside the urban core. However, services are not uniformly distributed due to that new peri-urban developments that are leapfrogging into vacant land without supporting infrastructure. The pace of the municipality in providing the necessary municipal services such as water and energy supply, as well as sanitation and refuse removal, is lagging behind the development of new and unplanned housing areas. The findings bring about information about the suburban livelihoods and how the administration of the peri-urban areas can respond to the needs of the inhabitants as well as to future challenges. For instance, to facilitate local development, recurrent and well-structured citizen dialogs with local groups to identify delivery failures are strongly recommended. In addition, the impact on ecosystem services by the city development and land use change stresses the need for guided urban development and expansion and also settlement upgrading programs in peri-urban zones to limit the bad effect on ecosystem services.

An APOS Analysis of Grade 11 Learners’ Errors and Misconceptions Under Hyperbolic Functions: A Case Study at a Rural High School in Limpopo Province in South Africa

This paper reports on the findings of a baseline study that fed on to a broader investigation exploring ICT integration in the teaching of functions. The baseline study was premised on the observation that the notion of function, despite being a fundamental and central idea in the mathematics school curriculum, presents pedagogical challenges to both teachers and learners. The study used the qualitative case study design to investigate Grade 11 mathematics learners’ errors and misconceptions under hyperbolic functions at a rural high school in the Limpopo province of South Africa. Informed by the constructivist APOS theory conception levels, learners’ errors were detected from their written responses in a diagnostic test. The learners were then individually interviewed during task-based interviews to infer on the misconceptions underlying their errors. Qualitative analysis of the data revealed the following categories of misconceptions: algebraic, conceptual, asymptotic, graphical, and notational misconceptions. The study established that errors, if diagnosed and corrected, are springboards and milestones to the formulation and construction of proper mathematical ideas. To resolve learners’ misconceptions, this study recommends that teachers should use explorative and discovery pedagogical strategies to enable learners realize their own misconceptions and self-correct. Based on the findings of this study, the integration of Information and Communication Technologies (ICTs) in teaching functions as an intervention strategy will be explored.
