This article addresses the problem of consistently poor learner performance in mapwork in secondary school geography in Namibia from the perspective of teachers. It presents the findings of a qualitative case study focused on understanding geography teachers’ perceptions and pedagogical practices of mapwork. Data were generated through a questionnaire administered to thirty teachers in fifteen secondary schools in the Ohangwena Region of Northern Namibia, and interviews and classroom observations were done with a purposive sample of three teachers. The study draws on Shulman’s ideas of teachers’ pedagogical content knowledge (1986, 1987) to interpret what the three teachers say about the teaching of mapwork and how they teach it. The findings reveal that the teachers are conscientious but ill-equipped to teach mapwork. Their classroom practices focus on teaching discrete map skills and procedural knowledge with little if any, attention given to spatial conceptual understanding and application of knowledge to solve problems. The study provides insights that may be of value to teachers, teacher educators and Senior Education Officers in Namibia and other southern African contexts when addressing the problem of low learning outcomes in mapwork.

Abstract Education for Sustainable Development (ESD) has been viewed as education that helps people develop the attitude, skills, and knowledge to make well-informed decisions for the benefit of the present and future generations. It aims at providing quality education through shared understanding and multi-disciplinary approaches in meeting the developmental and environmental apprehension for a sustainable future. Many theorists envisaged ESD as enhancing active involvement of learners both in school and out of school learning initiatives to acquire knowledge about sustainable development issues. The present paper discusses Namibian school teachers’ (n=9) perceptions of ESD and the teachers’ teaching practices using a qualitative-explorative study design. The data were gathered through two semi-structured interviews and lesson observations. The findings have revealed that senior secondary school teachers perceive ESD in terms of knowledge acquisition about the environment in order to use its resources sustainably for the benefit of future generations. The study has also revealed that teachers have positive sentiment toward the inclusion of ESD into the senior secondary school curriculum. Following this, they suggested that ESD should be either implemented as an independent subject or integrated with other existing subjects as a multi-disciplinary subject.

Purpose of the study: This study aims to explore the cognitive structures and identify the misconceptions experienced by secondary school students in the respiration topic.
 Methodology: This study is a qualitative study. The instruments used for data collection were the Word Association Test (WAT) and the Questionnaire of Writing Sentence (QWS). The data obtained were in word form. The breakpoint technique was used to analyze the data for WAT while the data for QWS were analyzed by category. Purposive sampling was applied in this study. A total of 23 forms four students comprising 12 boys and 11 girls participated in this study.
 Main Findings: The result showed that the students’ cognitive structures in the respiration topic were incomplete. The students were unable to form a comprehensive relationship for the given keywords, and there were also weak or incorrect associations. The misconceptions that had been identified are largely related to the keywords about cell respiration, anaerobic respiration, and breathing mechanism.
 Applications of this study: This study provides insights into the students’ cognitive structures and misconceptions about respiration. Thus, it will be useful for teachers in planning their teaching strategies so that they can improve the students’ cognitive structures as well as avoid misconceptions.
 Novelty: Most of the previous studies only focused on the identification of misconceptions without further investigation into the students’ cognitive structures, especially on the respiration topic. Thus, this study investigates the cognitive structures and misconceptions specifically among secondary school students who have learned respiration in biology.

High percentage of secondary school students was found that they were lack of understanding of the relationship between photosynthesis and respiration in plants. They did not fully understand the importance and function about plant respiration. Thus, this study designed to develop a valid and reliable instrument in two- tier multiple choice questions format which called Photosynthesis and Plant Respiration Diagnostic Test (PRDT) to assess the common types of misconceptions related to this topic among form four students (Grade 10) in Malaysia. Survey research method was applied in this study. There were 500 participants from 15 secondary schools were involved. 45 minutes were given to the participants in answering 18 two- tier diagnostic test items. The psychometric properties of the instrument had been tested using Rasch analysis. The result found that the newly developed instrument was valid and reliable. It brought the significant contribution in teaching and learning, especially classroom assessment practice in Biology subject.

The study aimed to establish teacher counsellors’ views on the factors impacting the implementation of guidance and counselling services in the Ohangwena region of Namibia. The study was quantitative in nature and used a non experimental design that involved a survey. The population of the study comprised of teacher counsellors in all senior secondary schools in Ohangwena region. Data were collected using questionnaires which were administered to a sample of twenty six (26) teacher counsellors. Teacher counsellors were purposively sampled. The data was analysed by use of descriptive statistics using The Statistical Package for the Social Sciences (SPSS). Based on the findings of this study teacher counsellors viewed inadequate training, high teaching loads and time constraints, lack of support given to teacher counsellors and lack of resources and facilities as key factors impacting the successful implementation ofschool guidance and counselling. It was thus recommended that the training of teacher counsellors in school guidance and counselling be improved, reduced workload for teacher counsellors, better resources and facilities for guidance and counselling, and for teacher counsellors to be supported in order for guidance and counselling to be successfully implemented in schools.

Background and objectivesIntermittent vital signs measurements are the current standard on hospital wards, typically recorded once every 8 hours. Early signs of deterioration may therefore be missed. Recent innovations have resulted in ‘wearable’ sensors, which may capture patient deterioration at an earlier stage. The objective of this study was to determine whether a wireless ‘patch’ sensor is able to reliably measure respiratory and heart rate continuously in high-risk surgical patients. The secondary objective was to explore the potential of the wireless sensor to serve as a safety monitor.DesignIn an observational methods comparisons study, patients were measured with both the wireless sensor and bedside routine standard for at least 24 hours.SettingUniversity teaching hospital, single centre.ParticipantsTwenty-five postoperative surgical patients admitted to a step-down unit.Outcome measuresPrimary outcome measures were limits of agreement and bias of heart rate and respiratory rate. Secondary outcome measures were sensor reliability, defined as time until first occurrence of data loss.Results1568 hours of vital signs data were analysed. Bias and 95% limits of agreement for heart rate were −1.1 (−8.8 to 6.5) beats per minute. For respiration rate, bias was −2.3 breaths per minute with wide limits of agreement (−15.8 to 11.2 breaths per minute). Median filtering over a 15 min period improved limits of agreement of both respiration and heart rate. 63% of the measurements were performed without data loss greater than 2 min. Overall data loss was limited (6% of time).ConclusionsThe wireless sensor is capable of accurately measuring heart rate, but accuracy for respiratory rate was outside acceptable limits. Remote monitoring has the potential to contribute to early recognition of physiological decline in high-risk patients. Future studies should focus on the ability to detect patient deterioration on low care environments and at home after discharge.

Full textAbstract:
Background Augmented reality (AR) has benefits and feasibility in emergency medicine, especially in the clinical care of patients, in operating rooms and inpatient facilities, and in the education and training of emergency care providers, but current research on this topic is sparse. Objective The primary objective is to evaluate the short-term and long-term effectiveness of the use of AR in the treatment of patients with anaphylactic shock. The secondary objectives are to evaluate the safety in the treatment of patients with anaphylactic shock, evaluate the short-term and long-term effectiveness of stress management in this process, and determine the experiences and attitudes towards the use of AR in education. Methods The study will be conducted in 3 phases. In the first phase, we will develop and test the scenario for simulation of anaphylactic shock and the evaluation scale for assessing the effect of the intervention. In the second phase, a single-blinded, randomized controlled trial will be conducted. In the third phase, the use of AR in teaching the management of anaphylactic shock using focus groups will be evaluated qualitatively. All participants will participate in a 1-day training program consisting of a lecture on emergency care and anaphylactic shock as well as exercises in manual dexterity (aspiration, airway management, alternative airway management, artificial respiration, chest compressions, safe defibrillation, oxygen application, use of medication during emergency care). The test group will also focus on education about anaphylactic shock in AR (the intervention). The main outcome will be the evaluation of the participants' performance in coping with a simulated scenario of anaphylactic shock using a high-fidelity simulator (simulator with high levels of realism) and a standardized patient in an educational and clinical environment. The study will be conducted with primary care physicians. Results A scenario for the simulation with a high-fidelity simulator and standardized patient has already been developed. For the time being, we are developing an evaluation scale and starting to recruit participants. We plan to complete the recruitment of participants by the end of December 2020, start the randomized controlled trial in January 2021, and finish 1 year later. The first results are expected to be submitted for publication in 2021. Conclusions This will be the first study to evaluate the effectiveness of the use of AR in medical teaching. Specifically, it will be based on a clinical case of anaphylactic shock at the primary care level. With our study, we also want to evaluate the translation of these educational results into clinical practice and assess their long-term impact.

Full textAbstract:
Orientation: Burnout seems to be particularly common amongst professionals who help and enable people to cope with the demands of their daily lives.Motivation for the study: The study focused on the magnitude and nature of burnout amongst Namibian teachers as well as the influence of biographical factors on their levels of burnout. Another aim was to determine the extent to which the results of this study correlate with research findings in other countries.Research design, approach and method: The researchers used a non-experimental research method. The study involved more than 300 secondary school teachers from the Windhoek region of Namibia. They administered the Maslach Burnout Inventory (MBI) and a biographical questionnaire to achieve the goals of the study.Main findings: The main findings of the study were that the participants experienced similar levels of burnout compared to teachers in other countries. This was especially true for emotional exhaustion. Teaching experience was the biographical variable that yielded the most significant positive correlation with burnout.Practical/managerial implications: The education authorities should address the emotional needs of secondary school teachers in Namibia urgently. They should introduce effective burnout intervention and prevention programmes. These programmes could result in higher levels of job satisfaction and educational effectiveness. They could also lead to increased general fulfilment and better teacher retention.

This study explored the link between teachers’ inputs and students’ academic achievement in the JSC Mathematics for the period 2006 to 2010. One hundred and fifty secondary schools selected from 573 secondary schools in the country constituted the target population. One hundred and sixty-four JSC mathematics teachers from the 150 secondary schools participated in the study, with the final JSC Mathematics results of the students serving as the dependent variable of the study. Mathematics teachers’ input data (academic qualifications, teaching experience and subject specialisation) were collected from a questionnaire developed by the researchers. Standard multiple regression was used to analyse the link between teachers’ inputs and students’ academic achievement in JSC Mathematics at P < 0.05and P < 0.10 respectively. The study found that teachers’ academic qualifications and subject specialisation had a significant and positive relationship with students’ academic achievement in JSC Mathematics. Teachers’ gender, however, was not significantly related to students’ academic achievement in JSC Mathematics. This is the first time within the Namibian context that we have empirically demonstrated the link between teachers’ inputs and students’ academic achievement in JSC Mathematics. The study therefore provides support for the policy initiatives that seek to link teachers’ academic qualifications, subject specialisation and teaching experience to employment and classroom allocation.

Full textAbstract:
The new curriculum in Namibia has introduced a new approach to teaching and learning requiring teachers to make use of learners’ prior everyday knowledge (PEK) including indigenous knowledge (IK) and practical work/activities. It further emphasizes some variations in teaching methods such as; the use of analogies, the use of mind maps, and so forth with the aim to actively involve learners in the learning process and develop skills to solve global challenges. The emphasis is on understanding of knowledge, skills and the will to use them appropriately throughout their lives. The main aim of this study was to understand and document how Biology teachers mediate learning of the topic respiration. Informed by an interpretive paradigm, a qualitative case study was conducted at two secondary schools in the Kunene region. The participants were selected using a convenience sampling. Data were gathered using three main sources, namely, documents, semi-structured interview questions which culminated into a questionnaire and observations. Triangulation was thus used to give credibility, objectivity and validity to the interpretation of the data. Data analysis in this case study involved a multi-stage process of organizing, coding and categorizing, synthesizing and summarizing. The audio recorded lessons were transcribed into text and I analyzed data using a colour coding technique by segmenting and labelling text to identify descriptions and broad themes in the data. Vygotsky’s Mediation of Learning and Social Constructivism in conjunction with Shulman’s Pedagogical Content Knowledge (PCK) informed the data analysis process. Teacher-learner interactions were the main theme for mediation of learning (social constructivist perspective), hence during analysis I paid more attention to moments where interactions evolved and I used PCK to gain insights in teaching and instructional strategies used by teachers. The findings of this study revealed that: 1) teachers endeavor to use a variety of teaching methods such as the use of a mind maps and question and answer method. Learners were keen to ask questions in order to understand this topic. 2) The study also revealed that a lack of practical activities is one of the challenges teachers are faced with. Based on my research findings, I therefore suggest that there is a need for continuous professional development of biology teachers and capacity building in order to improve both their content and pedagogical content knowledge.

Full textAbstract:
Lightning as a natural phenomenon is shallowly presented in the Namibian curriculum documents such as the syllabus and textbooks. This gap in curriculum triggered my interest to investigate whether learners’ meaning-making in static electricity was enabled or constrained by elicitation and integration of their cultural beliefs and experiences about lightning and by their practical activities. This study was conducted with my grade 8 learners at the school where I am currently teaching. The school is located in a rural area in Ohangwena region in Northern Namibia. The study is situated within an interpretive paradigm. Within the interpretive paradigm, a qualitative case study approach was adopted. I considered this methodological orientation appropriate in this study as it allowed me to use the following data gathering methods: document analysis, brainstorming, discussions and presentations, semi-structured interview, focus group interview, observation and an assessment test. Multiple methods to gather data were used for triangulation and validation purposes. For data analysis purposes, the data sets were colour-coded to derive themes and analytical statements. Ethical considerations were also taken seriously in this study and all participants gave consent. An analysis of data revealed that there is no learning objective or basic competence in the Namibian Physical Science syllabus for grade 8-10 that requires learners to bring in their cultural beliefs and experiences, in particular, about lightning. Yet the study revealed that learners possess a lot of prior everyday scientific and non-scientific knowledge and experiences about lightning that they had acquired from their communities. Also, mobilization of learners' everyday knowledge and experiences about lightning enabled learner engagement during the science lessons. Likewise, engaging learners in practical activities in static electricity helped them to make meaning of scientific concepts. Based on my research findings, I therefore, recommend that learners' prior everyday knowledge and experiences about lightning should be incorporated during teaching and learning of the topic on static electricity.

This qualitative study reports on critical reflective teaching by three mathematics teachers and how it shapes their classroom practice. The study was carried out in three secondary schools in Rundu in northern Namibia. The study employed a case study method. The selection of teachers was based on their rich practical professional knowledge and exemplary teaching practices. Data collection and analysis was done through an interpretive approach. Interviews and document analyses were the two research tools used, not only for the collection of data but for triangulation also. Interpretations of the findings were validated through member checking. Critical reflective teaching involves thought and action, and it raises teachers’ consciousness of what they do. Through critical reflective practice, teachers scrutinize their beliefs and knowledge of the subject and their practice. Furthermore critical reflective practice may get teachers into a disposition to find alternatives to improve their teaching. In this study, the findings are that participants reflect extensively on their classroom practice. The teachers pointed out that reflection on practice enables them to analyse and evaluate their teaching in line with effective mathematics teaching. They emphasised that critical reflection leads to the identification of weaknesses in teachers’ classroom practice. This culminates in better planning whereby alternative approaches to teaching are exercised. Because of its potential to improve teaching and enhance professional development it is therefore recommended that mathematics teachers be exposed to skills that enhance critical reflective teaching practice. Teachers need to familiarise themselves with the concept of critical reflective teaching in mathematics to meet the demands of superior quality teaching.

Full textAbstract:
Quality mathematics education relies on effective pedagogy which offers students appropriate and rich opportunities to develop their mathematical proficiency (MP) and intellectual autonomy in learning mathematics. This qualitative case study aimed to explore and analyse selected effective mathematics teachers' proficiency in the area of geometry in five secondary schools in five different Namibia educational regions. The sample was purposefully selected and comprised five mathematics teachers, identified locally as being effective practitioners by their peers, Education Ministry officials and the staff of the University of Namibia (UNAM). The schools where the selected teachers taught were all high performing Namibian schools in terms of students' mathematics performance in the annual national examinations. The general picture of students' poor performance in mathematics in Namibia is no different to other sub-Saharan countries and it is the teachers who unfortunately bear the brunt of the criticism. There are, however, beacons of excellence in Namibia and these often go unnoticed and are seldom written about. It is the purpose of this study to focus on these high achievers and analyse the practices of these teachers so that the rest of Namibia can learn from their practices and experience what is possible in the Namibian context. The mathematical content and context focus of this study was geometry. This qualitative study adopted a multiple case study approach and was framed within an interpretive paradigm. The data were collected through individual questionnaires, classroom lesson observations and in-depth open-ended and semi-structured interviews with the participating teachers. These interviews took the form of post lesson reflective and stimulated recall analysis sessions. An adapted framework based on the Kilpatrick, Swafford and Findell's (2001) five strands of teaching for MP was developed as a conceptual and analytical lens to analyse the selected teachers' practice. The developed coding and the descriptive narrative vignettes of their teaching enabled a qualitative analysis of what teachers said contributed to their effectiveness and how they developed MP in students. An enactivist theoretical lens was used to complement the Kilpatrick et al.'s (2001) analytical framework. This enabled a deeper analysis of teacher teaching practice in terms of their embodied mathematical knowledge, actions and interactions with students. procedural fluency (PF) and productive disposition (PD), were addressed regularly by all five participating teachers. Evidence of addressing either the development of students' strategic competence (SC) or adaptive reasoning (AR) appeared rarely. Of particular interest in this study was that the strand of PD was the glue that held the other four strands of MP together. PD was manifested in many different ways in varying degrees. PD was characterised by a high level of content knowledge, rich personal experience, sustained commitment, effective and careful preparation for lessons, high expectations of themselves and learners, collegiality, passion for mathematics and an excellent work ethic. In addition, the teachers' geometry teaching practices were characterised by making use of real-world connections, manipulatives and representations, encouraging a collaborative approach and working together to show that geometry constituted a bridge between the concrete and abstract. The findings of the study have led me, the author, to suggest a ten (10) principles framework and seven (7) key interrelated factors for effective teaching, as a practical guide for teachers. This study argues that the instructional practices enacted by the participating teachers, who were perceived to be effective, aligned well with practices informed by the five strands of the Kilpatrick et al.'s (2001) model and the four concepts of autopoesis, co-emergence, structural determinism and embodiment of the enactivist approach. The study concludes with recommendations for effective pedagogical practices in the teaching of geometry, and opportunities for further research.

Though research has been conducted on many issues since Namibia's independence in 1990, none of these studies has investigated how English Second Language (ESL) teachers teach and support struggling adolescent readers (SARs) to read. Utilising qualitative research techniques such as classroom observations, semi-structured interviews and document analysis, this case study looked at strategies, methods, and resources used by five ESL secondary school teachers to teach SARs to read in two regions in Namibia, Caprivi and Otjozondjupa regions. Two of the five participants were male teachers. The presence of SARs in the classes observed was established by using informal methods such as the ESL teachers' experience (Caprivi region), while a sample of questions from PIRLS 2001 (Mullis, Martin, Gonzalez, & Kennedy (2003) was compiled to form a test used in the Otjozondjupa region. The findings show that despite undergoing initial teacher training and majoring in English, the five ESL secondary school teachers were not trained to teach SARs either how to read or how to support them. In addition, the study found that there was a shortage of reading materials in all five selected schools.

Full textAbstract:
The study examined the use of multiple representations such as the real world, written symbols, spoken symbols, diagrams and manipulatives by learners to promote the learning of percentages and fractions through social interaction. This investigation was carried out through a teaching and learning programme which was developed and implemented by me, the researcher. The effect of the implemented programme was the main focus of the research. The qualitative study was oriented in the interpretive paradigm – a paradigm that seeks to understand the meaning attached to human actions. Twenty learners participated in the implementation of the programme and 9 learners were selected for focus group interviews. The purpose of the interviews was to explore learners' understanding and feelings about the use of multiple representations in the learning of percentages and fractions through social interactions. The other tools employed in this study were pre-and-post diagnostic tests, observations, learners' work and a journal. The pre-test was used to determine learners' prior knowledge for the program design and implementation, while the post-test and learners' work were used to analyze the effect of the programme. Observations were used to investigate how multiple representations promoted or did not promote the learning of percentages and fractions. The teacher's journal was to record and reflect on any relevant information gathered on each lesson observed. The data shows that the effective use of multiple representations helped learners learn the concept of percentages and fractions better. Learners were able to look at representations in useful ways; multiple representations made some aspects of the concept clear; and multiple representations enabled learners to correct errors. Through the interaction between the teacher and learners, the following was found: all the learners changed words to change focus; learners made links between multiple representations; the learners deepened their concepts of percentages and fractions; learners could convert between fractions using multiple representations; learners could work out percentages of a quantity; and learners could express one quantity as a percentage of another. Furthermore, through the interaction between learners and learners all learners could identify more equivalent fractions of an initial fraction which was given to them; and they could increase and decrease a quantity by a given percentage. On the basis of this research, it can be concluded that the programme promoted the learning of percentages and fractions through three effective methodologies. The first methodology consisted of the effective use of multiple representations; the second methodology concerned the interaction between the teacher and learner during the learning process and the last methodology related to the interaction between the learners - interactions that were not strongly mediated by the teacher. I would recommend that teachers use these three effective approaches when teaching percentages and fractions to promote the learning of the concepts.

Full textAbstract:
This paper reports findings on how Namibian secondary school Life Skills teachers are exercising their agency to teach or not to teach Sexuality and HIV and AIDS, a subject which is regarded as sensitive and has been surrounded by secrecy and has issues which are cloaked by silence and taboos. The aim of the study was to explore the structural and cultural factors that shape the responses and experiences of Life Skills teachers in teaching sexuality and HIV and AIDS. The study was conducted through observations and interviews with four full-time Life Skills teachers. Document analysis was carried out throughout the study in which lesson plans, portfolios, assessment forms, Life Skills syllabuses, schemes of works, national curriculum documents and subject policy on HIV and AIDS were analysed. The data were analysed by identifying categories, codes and themes using the analytic dualism framework, and the literature review was used to summarise the findings. The study revealed that all teachers operate in an environment that consists of the National structures such as high teacher: learner ratio in their classrooms that they have to teach Life Skills and do day to day counselling, a lack of teaching and learning support material that they should use to scaffold the learning of sexuality and HIV and AIDS, and little time allocated to Life Skills teaching. The same study also revealed that the teaching of Life Skills is hampered by the cultural structures which emerged from teachers’ discourses as evidenced from the data which shows that cultural properties have powers that condition teachers in teaching sexuality and HIV and AIDS. This included learners’ silence in sex-related discussion versus teachers’ position; discourses on the importance of full-time Life Skills teachers in school; comfort in teaching selected topics in Life Skills; Life Skills teachers’ perceptions on parents’ feelings on teaching sexuality and HIV and AIDS in schools, and perceptions on the Life Skills teachers’ position and teaching sexuality and sex education. While the findings revealed that teachers are conditioned by the structural and cultural conditions that acted as constraints to teaching sexuality and HIV and AIDS, the observations revealed agency on their part. The study finding depicts instances where teachers acted in agreement or in contravention of the structural and cultural pressures or conditions in their environments.

Full textAbstract:
The Namibian Physical Science Higher Level Syllabus requires students to study the topic on chemical equilibrium. This section has proven to be one of the most difficult for Namibian learners as reflected by their poor responses to questions in the Grade 12 NSSC ‘H’ examinations. Triggered by these discoveries, I decided to conduct a research on how teachers mediate learning of the topic on chemical equilibrium in a Namibian context. Conducted at a private school in Windhoek, the study involved two experienced Grade 11 Physical Science teachers renowned for good results. I adopted a qualitative case study underpinned by an interpretive paradigm. Sense making of concepts on chemical equilibrium was my unit of analysis. To generate data, I used document analysis, semi-structured interviews, lesson observations, which were videotaped as well as stimulated recall interviews. Vygotsky’s mediation of learning and social constructivism blended with Shulman’s pedagogical content knowledge (PCK) were the theoretical frameworks adopted in the study. During the analysis process, there was grouping of data into categories. These included teacher-learner interactions as emphasized by Vygotsky’s mediation of learning and learners’ challenges according to PCK. I used an inductive approach to identify emerging themes from my data. The themes were colour coded and the developed into analytical statements. Data triangulation, member checking, and peer review ensured data validity and trustworthiness. Stimulated recall interviews conducted while watching the videos with the two teachers, complemented these approaches. My findings were that teachers extensively used various meditational tools such as prior knowledge, language, analogies and an equilibrium game to mediate learning. The teachers experienced numerous challenges during mediation of learning, including language difficulties and learners’ failure to comprehend complex chemical equilibrium concepts. Notwithstanding, the teachers in this study managed to some extent to overcome the challenges by exhibiting facets of advanced PCK.

Full textAbstract:
The proliferation in the number of schools offering junior secondary education in Namibia since independence in 1990 has led to an increase in the number of learners in the classroom and has created a wide range of mathematical proficiency among learners entering senior secondary education in grade 11. This broad range of basic mathematical ability among these learners, together with increasing classroom numbers has caused problems for the senior secondary mathematics teachers (Batchelor, 2004). The study shows that diagnostic testing can prove to be useful in assessing learners’ mathematical preparedness by identifying learners’ areas of weakness, which have hindered their mathematics learning and performance. Taking the results of a diagnostic test into consideration could help teachers cater for their learners who need remediation classes as early as possible before extending the mathematics curriculum. Setting and using diagnostic testing requires careful consideration; there are many pitfalls that are highlighted in this research. These include question coverage and general analysis of category totals.

Full textAbstract:
The aim of this case study was to examine, analyze and report on the findings of the experiences of selected mathematics teachers when they used the van Hiele phases of instruction in designing and implementing a Grade 11 circle geometry teaching programme. The sample consisted of three selected mathematics teachers from the school where the researcher teaches. This school is located in the Oshikoto Education Region in Namibia. The school serves a multicultural group of 759 learners from a middle-class economic background. The site and participants were selected conveniently as the researcher had unrestricted access to both the facilities and the participants. This research takes the form of a case study and is underpinned by the interpretive paradigm. Data for this research was collected using a variety of techniques such as interviews, classroom observation and document analysis. This facilitated easy triangulation of the data. The findings of this research make four claims with regard to the experiences of the mathematics teachers with designing and implementing the circle geometry teaching programme using the five van Hiele phases of instruction as a conceptual framework. The findings revealed that firstly, all three participating mathematics teachers used and implemented all the five van Hiele phases of instruction in their lessons I observed. Secondly, the teachers navigated quite freely from one phase of instruction to the next, but also returned to the earlier phases for clarification and reinforcement in their teaching. Thirdly, the teachers saw the phases of instruction as a good pedagogical tool or template for planning and presenting lessons. Fourthly, the majority of the learners followed the instructions and seemed to obtain the answers faster than expected. The lesson presentations were lively and both teachers and learners communicated at length to discover angle properties of circles while developing and nurturing the technical language of geometry.

Full textAbstract:
This qualitative study examined the roles of the school management teams in curriculum delivery during COVID-19 and beyond. The closure of the schools due to the COVID-19 pandemic caused serious disruptions to teaching and learning. Learners were expected to be engaged in learning processes via different platforms. The school management teams were given enormous responsibilities to ensure planning, implementing, and monitoring curriculum delivery during and post COVID-19. Twenty participants are purposefully selected from 10 schools ranging from primary to secondary. Focus group interviews and document analysis were used to collect data. The authors followed the thematic approach in analyzing data. The study revealed that the amount of teaching is not significant as only the quality of learning matters. It proved that planning is the best approach to academic outcomes. The authors hope the study would provide insight into lived experiences of school management teams in curriculum planning, implementation, and monitoring of curriculum delivery amidst COVID-19 and beyond.
