Thesis (PhD)--Stellenbosch University, 2015. / ENGLISH ABSTRACT: This study focuses on the lived experiences of primary school teachers within a culture of performativity. The French philosopher, Jean-Francois Lyotard (1984) more than anyone else gave credence to the notion of ‘performativity’ in education which he used to represent political and bureaucratic mechanisms of control. Embedded in regulatory mechanisms there are performance indicators such as ‘monitoring systems’ with associated ‘production of information’, that according to Ball (2003) engenders the ‘terrors of performativity’. To conform to the regulatory mechanisms the performativity culture in schools, pressure is increasingly placed on teachers to demonstrate their accountability to education authorities for the responsibilities delegated to them. The literature review does not only seeks to give meaning to key terms and concepts relevant to the study, but also aims to define the operational. Relevant terms included: accountability, professionalism, performance and performativity. In the discussion it is shown that there is a close underlying relationship between performativity and performance, between performativity and accountability, and between performativity and professionalism. In order to answer the main research question and to align logically to the purpose of the study, the researcher conducted a qualitative research study within the interpretative research paradigm. The study was guided by the phenomenological research approach – and more specifically by the hermeneutical-phenomenological research method of Max van Manen (1990). Two data collection methods were employed: protocol narratives (descriptions of lived experiences) and in-depth semi-structured phenomenological interviews. In this study a thematic analytical approach was followed whereby the researcher identified emerging themes from the collected data. Different steps were taken to increase the internal validity of the study and to give attention to the ethical aspects that emerged during the investigation. In this study it is evident that performativity, with its emphasis on effectiveness, efficiency and quality, is currently the most powerful and pervasive discourse in education. The description of the results shows that teachers tend to be swallowed up by the demands of performativity – so much so that teachers are overwhelmed by the ‘terrors of performativity’. Teachers’ ‘escape’ from the ‘imprisonment’ of performativity is not only associated with distorted side Stellenbosch University https://scholar.sun.ac.za viii effects, but there are also physiological and emotional processes that teachers are confronted with in their attempts conform to the regulatory systems. The study found that the undesirable side effects of performativity serve and a push factor for the early exit of teachers from the profession. / AFRIKAANSE OPSOMMING: Hierdie studie fokus op die geleefde ervarings van primêre skoolonderwysers binne ‘n kultuur van performatiwiteit. Die Franse filosoof, Jean-Francois Lyotard (1984) wat meer as enigeen die betekenis van performatiwiteit in die onderwys blootgelê het, gebruik die nosie van ‘performatiwiteit’ om politieke en burokratiese meganismes van beheer voor te stel. Ingebed in die regulerende meganismes is daar prestasie-aanduiders soos onder andere ‘moniteringsisteme’ met gepaardgaande ‘produksie van inligting’, wat volgens Stephen Ball (2003) aanleiding gee tot die ‘terreurs van performatiwiteit’. Ten einde te konformeer tot die regulerende meganismes is daar binne die performatiewe klimaat in die skool toenemende druk op onderwysers om te demonstreer dat hulle toerekenbaar is aan die onderwysowerhede vir die verantwoordelikhede wat aan hulle opgedra is. In die lieratuuroorsig is nie net ‘n oorsig gegee van die betekenisse van kernterme en – konsepte wat relevant tot hierdie studie is nie, maar ook is gepoog om dit operatief te definieer. Relevante begrippe is onder andere toerekenbaarheid, professionalisme, prestasie en performatiwiteit. In die bespreking is aangetoon dat daar ‘n noue onderlinge verband tussen performatiwiteit en prestasie, tussen performatiwiteit en toerekenbaarheid, en tussen performatiwiteit en professionalisme bestaan. Om die sentrale navorsingsvraag te beantwoord en logies met die doel van die studie in te skakel, het die navorser ‘n kwalitatiewe navorsingstudie uit die interpretiwistiese navorsingsparadigma onderneem. Die fenomenologiese navorsingsbenadering – en meer spesifiek, die hermeneuties-fenomenologiese navorsingsmetode van Max van Manen (1990) het hierdie studie gerig. Daar is gebruik gemaak van twee data-insamelingsmetodes, te wete protokol skryfwerk (geleefde ervarings-beskrywings) en semi-gestruktureerde in-diepte fenomenologiese onderhoude. In hierdie studie is ‘n tematiese analitiese benadering gevolg deurdat die navorser die ontluikende temas in die ingesamelde data geïdentifiseer het. Verskillende stappe is gedoen om veral die interne geldigheid van die studie te verhoog en aandag te gee aan etiese aspekte wat tydens die ondersoek na vore gekom het. Uit hierdie studie blyk dit dat performatiwiteit, met sy klem op effektiwiteit, doeltreffendheid en kwaliteit, huidiglik die mees magtigste en deurdringende diskoers in die onderwys is. Uit die Stellenbosch University https://scholar.sun.ac.za vi beskrywing van die resultate is dit duidelik dat onderwysers neig om deur die eise van performatiwiteit verswelg te raak – soveel so dat onderwyser oorweldig word deur die ‘terreurs van performatiwiteit’. Onderwysers se ‘ontsnapping’ uit die ‘gevangenskap’ van performatiwiteit gaan nie net gepaard met bepaalde verwronge opvoedkundige newe-effekte nie, maar ook is daar die fisiologiese en emosionele prosesse wat onderwysers moet verduur in hul pogings om tot die regulerende stelsels te konformeer. In die studie is bevind dat die ongewenste newe-effekte van performatiwiteit dien as stootfaktore wat onderwysers beweeg om die onderwys vroeg te laat verlaat.

This study involves an examination of the neurocognitive correlates of subscales of the Conners' Rating Scale - Revised (CRS-R), an ADHD behavioral rating form, in both a child (n=72) and an adolescent (n=49) sample. While both behavioral rating forms and neuropsychological measures are commonly employed in pediatric clinical evaluations, these two forms of assessment do not generally converge as expected. The purpose of the current research was to examine and compare the abilities of intellectual, academic, attentional, and executive skills to account for variance in parent and teacher ratings of behavior across two pediatric age groups in a clinical setting. Additionally, the study compared the relationships between behavioral ratings and cognition in children versus adolescents. The study found parent and teacher ratings of cognitive problems and inattention to be better accounted for by general cognitive ability than by attention and executive skills in children. Conversely, ratings of child hyperactivity, as completed by both parents and teachers, were better explained by attention and executive skills. General cognitive and academic abilities best accounted for parent ratings of overall ADHD likelihood, whereas teacher ratings of ADHD likelihood were equally accounted for by general cognitive abilities and attentional and executive skills. Neither general cognitive and academic abilities nor attention and executive skills accounted for a significant proportion of the variance in the adolescent sample. Furthermore, results showed that the variance in parent and teacher ratings of behavior was significantly accounted for by neurocognitive test performance across ratings subscales for child, but not adolescent clients. Overall, the results suggest that ADHD behavioral rating form accuracy varies according to subscale, informant, and age group. In child clients, ADHD behavioral ratings converged with theoretically associated cognitive abilities for subscales assessing hyperactive, but not inattentive behaviors. Both parent and teacher informants appear to take children's overall cognitive and academic abilities into consideration more so than attentional and executive skills when rating inattentive behaviors. This suggests either rating form or informant inaccuracy in identifying specific problems in attention and organization. Parents, in particular, appear to be relatively poorer raters of child behavior than teachers as only teacher ratings of overall ADHD likelihood were accounted for by attentional and executive skills. Parent and teacher ratings of behavior appear to be of questionable accuracy across ADHD related behaviors in the assessment of adolescents. As behavioral ratings were not related to cognition in the 11-17-year-old sample, ADHD behavioral rating forms appear to demonstrate poor convergent validity in adolescents. The finding that ratings of behavior were significantly related to cognition in children, but not in adolescents, suggests the presence of age-dependent differences in the presentation of ADHD symptoms or the accuracy of assessment tools between children and adolescents. Clinicians are encouraged to use caution when interpreting ratings of adolescent ADHD behavior and ratings of child inattentive behavior, as these scales may often not assess their purported constructs.

The Borg 6–20 rating of perceived exertion (RPE) scale is a common measure reported during exercise testing and training, and is usually taken as a response measurement to provide a subjective assessment of exercise intensity. A lesser used application of the scale is for regulating exercise intensity, referred to as its ‘production mode’. Recent research on this topic initiated by Eston et al. (2005) has led to a novel application of this procedure as a means of predicting an individual’s maximal oxygen uptake ( O2max) via a perceptually-regulated exercise test (PRET). The PRET could play a significant role in guiding exercise prescription and monitoring cardiorespiratory fitness levels in situations where the normal heart rate response is affected. The aim of this thesis is to develop further and test the integrity of the PRET technique. Firstly, a review of the evidence on the validity and reliability of the Borg RPE scale when used to regulate exercise intensity in healthy and unhealthy adults is presented, as to-date, no scholarly publication has synthesised the body of knowledge on this specific application of the scale. Subsequently, four studies were completed to investigate the effects of different methodological variations on the predictive capabilities of the PRET, including an examination (for the first time) of its utility among heart failure patients (Study 4). Study 1 re-visited the validity and reliability of the PRET technique utilising a modified protocol of differing durations (2 and 4 min bouts), with revised instructions and placing the graded exercise test (GXT) as the final trial during cycle ergometry. Superior results were observed to those reported in previous investigations (Eston et al., 2008; Faulkner et al. 2007; Eston et al., 2006) during the 3 min trial, further reinforcing the validity and reliability of this technique. Accordingly, Study 2 was the first to investigate the reliability and validity of a treadmill PRET protocol with a ceiling intensity of RPE 15, rather than RPE 17, and observed that a safer modified PRET (with practice) provides acceptably valid and reliable predictions of O2max in healthy adults. In addition, Study 3 extended the research thus far by investigating the PRET protocol during cycle exercise, once again with a ceiling intensity of RPE 15, and demonstrated that (with practice) a cycle-based PRET can yield reliable and valid predictions of O2max that compare favourably to previous investigations. Finally, given that the research employing a PRET has unanimously alluded to its likely value in clinical populations among whom heart rate as a physiological response to exercise is affected (e.g. via medication) and precluded as a means predicting O2max, Study 4 investigated the utility of a PRET in a beta-blocked population of heart failure patients. In the event, it was observed that a PRET (up to RPE 15) was too strenuous and needs to be capped at an intensity of RPE 13 in this population. In addition a continuous protocol seemed unsuitable due to its length and it was recommended that a discontinuous PRET protocol be investigated. Future research needs to investigate the utilisation of the PRET (i) in different exercise modes; (ii) determine the optimum number of practice trials required; (iii) whether a discontinuous or continuous protocol is more appropariate; (iv) whether the extrapolation should be made to RPE 19 or 20 and; (v) whether the PRET can be employed succesfully in other clinical populations.

The investigation of expertise in teaching has followed the lead of research in domains other than education in that it has focused on the cognitive processes that define expertise. This study has shifted the focus to the actual classroom teaching, comparing expert, novice, and postulant (those without pedagogical training) teachers. Each of six teachers (two experts, two novices, and two postulants) taught the same unfamiliar lesson to the same group of students, in the same classroom. These half hour lessons were videotaped. Two aspects make this study unique. First, the teaching situation was controlled to the extent that each teacher taught the same lesson to the same students. This was done to try to separate expertise from the experience gained from teaching a familiar lesson to students known to the teacher. The second aspect pertains to the method of analysis. Instead of viewing these tapes from just one perspective, four perspectives were used. Observers knowledgeable in the areas of subject matter knowledge and delivery, connoisseurship and criticism, nonverbal communication, and teacher evaluation instrumentation viewed each of the six tapes and analyzed what they saw from their individual perspectives. These analyses were then content analyzed by the author. Results and discussion were first analyzed for each perspective separately, comparing the three groups of teachers for similarities and differences. This was followed by a discussion of similarities and differences among the four perspectives, particularly focusing on the interplay of the four perspectives within the three groups of teachers. A key point made was the diversity of information provided by each perspective and the unique insights provided from the use of all four.

The culture of teaching in most South African schools is one of isolation and independence. Once individuals have qualified as teachers, there is a strong sense of getting on with the job of teaching, rather than beginning a journey of critical reflection and change. This study aims to address and contribute towards shifting this ethos and establishing a joint reflective school culture.

<p>The purpose of the study was to investigate prospective &lsquo / A&rsquo / level mathematics teachers&rsquo / knowledge of the concept of a function. The study was a case study of six prospective Zimbabwean teachers who were majoring in mathematics with the intention of completing a programme leading to certification as secondary mathematics teachers. At the time of the study the six prospective teachers were in their final year of study. Prospective teachers&rsquo / knowledge of the concept of a function was assessed through task-based interviews and reflective interviews. These interviews, which were done over a period of three months, were structured to capture the prospective teachers&rsquo / subject matter knowledge and pedagogical content knowledge for teaching the concept of a function. The interviews were also meant to capture the prospective teachers&rsquo / underlining pedagogical reasons for their choices of the examples, representations and teaching approaches when planning to teach the concept.</p> <p>As part of the study a theoretical framework for understanding prospective teachers&rsquo / knowledge of the concept of a function was developed. The framework, which was developed, was used as an analytical tool in analyzing prospective teachers knowledge of the concept of a function. The results of the study indicated that the prospective teachers had a process conception of a function although some of them had given a set-theoretic definition of a function in which a function is perceived as a mathematical object. They also confined the notion of a function to sets of real numbers. Functions defined on other mathematical objects (for example, the differential operator and the determinant function) were not considered as functions by five of the six prospective teachers.</p>
