African women with a doctorate in mathematics 1


African index History Topics Index

The International and African Mathematical Union Commission on the History of Mathematics in Africa produced a Special Issue of their AMUCHMA Newsletter 33 in 2006 which listed women born in Africa or who had spent much of their careers in an African country who had been awarded a doctorate in mathematics or mathematics education up to 2005. We note that AMUCHMA's list is extracted from Paulus Gerdes's book African Doctorates in Mathematics. A Catalogue (African Academy of Sciences Publishers, Nairobi, 2006). We give below a version of AMUCHMA's list to which we have made some corrections and added biographical data when we could find it. Anyone who has information about further corrections/additions, please let us know and we will update this list.

The list below contains those whose PhDs were gained between 1963 and 1996. It is ordered chronologically and then alphabetically inside each year.

    University: Columbia University (New York, USA).
    Biographical Data: She studied for her Ed.D. at the Teachers College of Columbia University. For her thesis she conducted a Piaget-oriented study of Nigerian children. A standardised interview schedule based on Piaget's tasks was used to investigate the theory that conservation, seriation, and classification develop concurrently. Etuk also examined the relationship of the development of number concepts to intelligence, the effect of sex differences on the development of number concepts, and differences in performances of children from modern and traditional homes. The subjects of Etuk's study were Yoruba-speaking pupils of seven primary schools. Results generally supported Piaget's theory. Etuk found only a slight relationship between intelligence and performance on number tasks. She found slight sex differences and that the children from modern homes performed at a higher level than earlier counterparts from traditional homes.

    Here is the Abstract of the 2013 paper listed above: "In the past, common people were expected to have skills in reading, writing and arithmetic to succeed to have a job. Philosophy and/or Science were required for reaching a high position and belonging to the national elite. In this new millennium, information, knowledge, science and technology constitute a real power, and an educated person is asked to be able to access, interpret and possess information, to understand science and use technology. The role of education has moved towards forging connections between knowledge development and its application to the workplace. So, critical thinking skills, problem-solving and creativity remained the key factors to be a successful worker. Therefore innovations and new trends were necessary to face the change from the industrial society to the current information society and to fulfil the high expectations of this new millennium. The implementation of ICT has then been in the forefront of education reforms in the developed countries. ICT stood to make the greatest impact on education as a whole and particularly on Science, Mathematics and Technology. This required some planned and systematic strategies to introduce and support ICT in education, as well as in the society as a whole, in terms of software, hardware, training and maintenance support. The integration of ICT aimed to offer a powerful teaching and learning resource, and interesting opportunities for self-learning, distance and modular. The introduced innovations in ICT implementation, focused first on the vision of using ICT as a teaching and learning aid."

Relations entre divers caractères de ses situations et le sens, la compréhension de l'apprentissage de ces notions [Study of school situations of the first teaching of number and numeration. Relationships between diverse characters of these situations and the meaning, the understanding of the learning of these notions].
    University: Université Bordeaux 1 (Bordeaux, France).
    Advisor: Guy Brousseau.
    Biographical Data: Here is an Abstract of her thesis: "Two didactic transpositions of the concept of numeration emerge through the study of teaching methods. In the first, numeration is a protomathematic object, and its teaching is contained in that of numbers. The pupil first learns mechanisms and then their meaning through various exercises. In the second, numeration is a mathematical object, subject of explicitly designated teaching. We note the loss of the meaning and context of knowledge. We propose a new transposition in which the relations between numeration and numbers are dialectical. In the new didactic situations, numeration serves to give meaning to numbers and to build new ones. The pupil constructs a system of representation of the numbers which he modifies, improves or rejects by the play of certain didactic variables."

    Biographical Data: Abstract of the thesis: "This research aims to study the conceptions expressed by Moroccan students and teachers at the end of secondary school about the notion of (simple) continuity of a function. In order to better achieve our objectives, we initially analysed the evolution of conceptions in the genesis of this notion, as well as the conceptions that have been conveyed by textbooks in Morocco since 1945. For the study of students' conceptions we used three means: the administration of a questionnaire to 311 students in 10 classes at the end of secondary school in Morocco; the organization of debates in each class on the answers to the questionnaire; conducting individual interviews with five students in each class. To study the conceptions of teachers and those they convey in teaching, we interviewed at length 20 teachers, including ten in charge of the ten previous experimental classes."

    Biographical Data: The name on her thesis is given as 'Antoinette Irène Rasolofoniaina'. Here is an Abstract of the thesis: "The study presented here focuses on factors that facilitate learning through reading. Different modalities of presentation of a text introducing the (congruence modulo m) were proposed to 1st grade students. After the reading, we asked the student to write down what they had retained from what had been read and we included a set of exercises to test the student's ability to apply what he had learned in the reading to solve problems. The main result observed was that the information best assimilated by the reader is that which satisfies both the following conditions: (i) It has been explicitly presented; (ii) it has been reused."
    She published Conditions d'apprentissage mathématique par la lecture (1984). This paper, based on her thesis, has the following Abstract: "This work examines some of the factors which facilitate learning mathematics through reading. For this, we take 11th grade students a reading which dealt with a concept new to the students ( congruence modulo m ). Different versions were distributed. In these versions, we varied some of the factors likely to facilitate the student's understanding of the new concept: an introducing problem, a paraphrase in every day language, a page of partially solved problems... After the reading, we asked the student to write down what they had retained from what had been read and we included a set of exercises to test the student s ability to apply what he had learned in the reading to solve problems. This study showed that the information in the reading that was both introduced and recycled to prove other concepts was best assimilated by the readers."

The maximum likelihood estimation procedure in the quaternion case is examined and the conclusion is reached that the estimation procedure is simplified if the unknown parameters of the associated real probability density function are estimated. The quaternion estimator is then obtained by regarding these estimators as the components of the quaternion estimator. By means of a example attention is given to a test criterion which can be used in the quaternion model."

    Here is the Summary of the 1987 paper: "The capillary instability of a viscous hollow cylinder is studied and the dispersion relation describing the characteristics of the model is derived. In the absence of viscosity, the configuration is found to be unstable for certain values of the wavelength and stable for all other values. As the viscosity becomes important, one has the same situation but there is no finite maximum mode of instability and the configuration will not have a tendency to break up at points separated by distances comparable to the circumference of the cylinder, but rather to give way at few distant places. Moreover for a certain value of the growth rate sigma, the viscosity has the effect of increasing the wavelength in comparison with the corresponding value when the inertia is predominant over the viscosity."

  57. Laurette PRETORIUS
    Country: South Africa
    Year: 1987.
    Degree: D.Sc.
    Thesis title: Gauss-type Quadrature Formulas for Spline Functions.
    University: Potchefstroom University for Christian Higher Education (South Africa).
    Advisor: Dirk P. Laurie.
    Biographical Data: She published Spline-Gauss rules and the Nyström method for solving integral equations in quantum scattering (1987) which was part of her thesis. The authors write: "This paper describes a method for constructing a Gauss quadrature formula that is exact for splines. The spline-Gauss quadrature is used in a Nystrom method for solving integral equations of the second kind. A practical application is provided by solving integral equations that arise in quantum scattering theory." At this time she was at the National Research Institute for Mathematical Sciences at the Council for Scientific and Industrial Research, Pretoria. She then worked at the University of South Africa in the Department of African Languages and the School of Computing University of South Africa Pretoria.
    Her many published papers on applications of computing to African languages include Finite-State Computational Morphology: An Analyzer Prototype For Zulu (2003), Experimental Bootstrapping of Morphological Analysers for Nguni Languages (2008), Introduction to the special issue on African Language Technology (2011), and The Multilingual Semantic Web as Virtual Knowledge Commons: The Case of the Under-Resourced South African Languages (2014).
    As an example of this work we give the Abstract of the 2003 paper: "As one of the largest of the 11 official languages of South Africa, Zulu is spoken by approximately 9 million people. It forms part of a language family which is characterized by rich agglutinating morphological structures. This paper discusses a prototype of a computational morphological analyzer for Zulu, built by means of the Xerox finite state tools, in particular lexc and xfst. In addition to considering both the morphotactics and the morphophonological alternation rules that apply, the focus is on implementation and other issues that need to be resolved in order to produce a useful software artefact for automated morphological analysis. The current status of the prototype is alluded to by providing morphological scope, that is the various word categories (parts of speech) that may be handled, and the lexical coverage in terms of the number of different Zulu roots that are included in the embedded lexicon of the analyzer. Preliminary testing and validation procedures are briefly discussed."

    Country: Egypt
    Year: 1988.
    Degree: Doctorat.
    Thesis title: Autour des algèbres de Malcev.
    University: Université de Montpellier II (France).
    Advisor: Artibano Micali.
    Biographical Data: She was born in 1953. She gave the following Abstract of her thesis: "Malcev's algebras are non-associative algebras satisfying certain identities, suggested by A I Malcev in 1955, and which always hold in the case of Lie algebras. As all subalgebras generated by two elements of a Malcev algebra is a Lie algebra, the Malcev algebras belong to the class of binary Lie algebras. Lie algebras remain an essential reference in the evolution of the theory of Malcev algebras. In 1967, Kuzmin defined, for Malcev algebras, the concept of Cartan subalgebras, an idea that will be widely developed in this work. By showing that its definition is equivalent to that of Lie algebras, the results known on Lie algebras have been extended more easily to Malcev algebras. A major part of this work is dedicated to the study of different sets of subalgebras of a Malcev algebra. Each time we study the relationships which may exist between such sets and those of the Cartan subalgebras. Through the concept of a dual isomorphism, a classification of a class of Malcev algebras is given. By showing that they are Lie, the results concerning Lie algebras with a dual can be extended to them."

    Year: 1988.
    Degree: Ph.D.
    Thesis title: A study of pseudospectral Mmethods for the solution of a nonlinear dispersive wave equation.
    University: University of Strathclyde (UK).
    Advisor: David M. Sloan.
    Biographical Data: She was awarded her Baccalaureate in Mathematics after studying at the Lycée Rabahi Nouar, Souk Ahras, Algeria (June 1979), a Diplôme d'études supérieures from Annaba University (June 1983), a Joint Matriculation Board after study at Bell School, Norwich, UK (March 1984), an M.Sc. in Modelling and Numerical Analysis from Oxford University, UK (October 1985), a Ph.D. in Applied Mathematics from Strathclyde University, UK (November 1988).
    The Abstract of the thesis is as follows: "This thesis examines time-stepping techniques for the numerical solution of the Korteweg - de Vries (KDV) equation by pseudospectral spatial discretization. The KDV equation is an ubiquitous nonlinear dispersive wave equation. To appreciate the numerical difficulties and to understand the need for solutions to such equations it is necessary to know a little about the fascinating array of solutions which arise in the study of dispersive wave equations. Accordingly, their physical occurrences and phenomena, and simple solutions are discussed in chapter one, with derivation of conservation conditions given therein in chapter two, a theoretical study of methods is considered and sufficient conditions for stability and convergence results are presented. This analysis is used in a later chapter to seek numerical solutions of the KDV equation. Chapter three mainly deals with problems with periodic boundary conditions. Various time discretization methods are studied and compared for accuracy and efficiency. The remainder of the thesis concerns a further generalization, allowing the investigation of stability and efficiations for Chebyshev pseudospectral methods and their applications to solve nonlinear dispersive wave equations, namely the KDV equation with general boundary conditions. Finally, a new domain-decomposition technique is adapted for pseudospectral methods and general conclusions and discussions are presented."
    She became a professor in the Institute of Mathematics, Université Badji Mokhtar de Annaba, Algeria, where she was appointed in 1989. She has published at least 16 papers including Spectral portrait for non-Hermitian large sparse matrices (2000), On finite spectral method for axisymmetric elliptic problem (2006), A study of a bi-phasic flow problem in porous media (2013), Numerical simulation for two-phase flow in a porous medium (2015), and Dynamical behaviour of miscibles fluids in porous media (2018).

    Thesis title: Use of auxiliary information in sampling theory.
    University: Southern Illinois University (Carbondale IL, USA).
    Advisor: Sudhakar Dharmadhikari.
    Biographical Data: Here is the Abstract of her thesis: "In sample surveys precision in estimating the unknown mean or the total of a finite population may be increased by using an auxiliary variable which is correlated with the study variable. In most of the survey studies, information on several auxiliary variables correlated with the variable under study is available. This thesis is concerned with the optimal use of multi-auxiliary variables. Given the means (or the totals) of auxiliary variables positively correlated with the character of interest, we construct a multivariate estimator for the population mean/total to be used with simple random sampling (srs) or with any probability proportional to size (pps) design. The estimator is at least as good as all the multivariate regression type and ratio type estimators found in the literature, under the given conditions. By constructing some strategies, we show that there are many ways to increase the accuracy of estimates by combining pps selection and estimators. Using the Hansen-Hurvitz estimator, we show that it may be better to combine measures of size. Using superpopulation models, we show that selecting a sample by pps of a single size measure or a combined size measure may be better than by srs; but with multi-auxiliary variables it is not clear which measure or combinations of measures of size is more appropriate."

    Thesis title: The impact of mathematics/science in-service teacher education programs on the Manzini region (Swaziland) elementary schools.
    University: Ohio University (USA).
    Biographical Data: Here is the Abstract of her thesis: "This study has examined the impact math/science inservice teacher education programs, on elementary schools of the Manzini region, provided since their inception in the early 1980s. The investigation entailed: (a) the personal backgrounds of the teachers in selected schools that participated in the workshops: (b) the physical environment under which teachers operate in their respective schools, (c) the skills obtained from the workshops in terms of classroom interaction needs that involve the use of different teaching methods in one lesson, the use of hands-on events in a lesson and the use of questions and responses by both teachers and pupils in a lesson, and (d) finally the effect of collegial support called the multiplier effect. This research combined three methodologies in collecting the data, a triangulation of three phases that used structured instruments of: a survey/questionnaire, interview and lesson observation. Demographic and qualitative data are presented to determine the impact of the Manzini region elementary school math/science inservice education programs in the classroom. The research carried explanations of the data that account for patterns of teacher information, the classroom environment and interaction observed in math/science lessons. Demographic data and open-ended question responses were provided by 109 elementary school teachers of the Manzini region in Swaziland through surveys. Ten of the respondents were further interviewed and 12 were observed while teaching mathematics and science in 12 different lessons. Analysis of averages, frequencies, percentages and ranges using pie, line and bar graphs were coupled with qualitative data from interviews and lesson observations to analyse, summarize and make recommendations for this research. The data analysis of all the four different sub-problems presented in this research reflect a positive impact of the math/science inservice education programs in the Manzini region elementary schools."

    Biographical Data: Here is an Abstract of her thesis: "This work deals with the numerical simulation of die-casting mold filing. It focuses mainly on turbulence modelling for non-stationary fluid flows. After a review of the various models described in the literature, our study deals with the simple zero-equation model and the more complex two-equation model of the k-e kind. After recalling the finite element methods used for solving laminar fluid flows (Chapter III), we describe in chapter IV the way the various models are taken into account in these methods. Two different formulations have been used, their results being quite similar: P2P0 elements with incompressibility penalization, and P2-P1 element using a mixed velocity-pressure formulation along with an Uzawa-like algorithm. With regard to (k, k / e) it was investigated with unsatisfactory results because it is far from the reference model k-e (Chapter V). A more efficient strategy has been the use of a modified Runge-Kutta time-integration scheme, which eliminates out-of-range (negative) values for the turbulence variables. Two cases of application of this model to the filling of molds (Chapter VI) have shown its capacity to account for the phenomena characteristic of unsteady turbulent flows with free surface."

    University: Université de Montréal (Canada).
    Advisor: Marc Moore.
    Biographical Data: Here is an Abstract of her thesis: "The first goal of this thesis is to establish new results about some random sets extracted from the Poisson and Voronoy tessellations of the plane. In addition to a random polygon we consider its neighbours and some aggregates of polygons. In particular, we introduce the concept of an amalgam generated by a polygon, that is the union of a polygon and all its neighbours. For each random polygonal set considered we study the number of sides, the perimeter and the area. We present all the algorithms to simulate the random sets considered and to compute their characteristics. The simulation study involve the generation of two millions independent realisations of each tessellations in a bounded region of the plane. Results are presented in the form of estimates (with standard deviations) and estimated distributions. Two indices are used to appreciate the degree of convexity of an amalgam; they involve respectively the perimeter and the area. For the Poisson tessellation it is shown that the convexity of an amalgam is related to the number of sides of the generating polygon. The second objective of this thesis is related to image analysis. We explore some properties of binary random mosaics obtained from the two processes considered in the first part. We introduce the concept of a patch in such an image. Algorithms to generate the portion of such a patch that is observable in a bounded region of the plane are constructed. It is also shown how some geometrical characteristics of this random set and its convex hull can be computed. A simulation study involving 4000 independent realisations of each of the Poisson and Voronoy images is reported. The empirical distribution of each of the two convexity indices mentioned above are presented. The one based on the area seems to depend only slightly on the intensity of the image generating process. We conclude by showing how this index could be used to discriminate between Poisson and Voronoy images."

    Thesis title: Aspects of estimation in the linear model with special reference to collinearity.
    University: University of Cape Town (South Africa).
    Advisors: Tim Dunne and Cas Troskie.
    Biographical Data: She has a Biometry degree from the University of Stellenbosch and a masters and PhD in Statistical Sciences from the University of Cape Town. Her Master's Degree thesis was Collinearity and consequences for estimation: a study and simulation (1990). The Abstract of the thesis begins: "Violations in the assumptions of the linear regression model lead to problems that make the ordinary least square estimator inappropriate. When the error terms are non-normal, the inference procedure that usually follows ordinary least squares estimation is no longer strictly valid. Collinearity, error terms that are non-normal and outliers are usually factors present to some degree in combination in a regression data set. Their effects may be confounded. In examining the factors separately the whole story is not told. We therefore set up a factorial design to investigate these problems under various scenarios."
    She held various positions in the Western Cape from biometrician in the Department of Agriculture, to computer science teacher and lecturer in mathematical and statistical sciences. She joined the Department of Statistical Sciences, University of Cape Town in 1999 as a senior lecturer, and become an Associated Professor in 2004. She was Deputy Head of the department since 2005 and Head of the department in 2009-2013. She published the paper A comparison of plug-in predictors for lognormal kriging (2016).
    The authors give the following Summary: "When skewed spatial data are encountered, a common procedure is to invoke lognormal kriging. The resultant naïve lognormal predictors are however biased. A family of optimal predictors which address this unbiasedness has been introduced into the literature by De Oliveira (2006). The behaviour of this family is well documented in the case of known covariance parameters. In contrast, when the covariance parameters are not known and must be estimated, the behaviour of the predictors is unknown. In the present paper, the performance of a subset of the family of predictors formulated by De Oliveira (2006), together with a predictor introduced by Abt et al. (1999), with 'plug-in' estimates of the covariance parameters introduced into the appropriate theoretical formulae, is investigated by means of a simulation study. Results based on eighteen scenarios describing a range of covariance structures and three performance criteria are presented and, in addition, results for a real world example are reported. The main features to emerge from the study are that the naïve predictor is negatively biased, that the lognormal predictor is representative of key predictors in the class introduced by De Oliveira (2006) and that the empirical mean squared prediction error severely underestimates the true value."

    University: Université de Paris 5 Sorbonne (France).
    Advisor: Gérard Vergnaud.
    Biographical Data: The Abstract of her doctoral thesis at the Université de Paris 5 is as follows: "The general aim of this dissertation is the analysis of the process of didactic transposition whose major aim is to challenge the illusion of transparency which affects the knowledge that is imparted. It hopes to achieve this by showing the differences between the intellectual and didactic functioning mechanisms. This dissertation has elected to consider the field of plane geometry because its use and role can be observed in the teaching of mathematics in the junior classes at the secondary school level. This example highlights the specific constraints of contextual meaning which require recourse in the process of transposition and also constitutes a mode of functioning. A distinction is made between constraints inherent in what is called the "noosphere" (the sphere of thought and decision-making), and constraints inherent in didactic functioning mechanisms through didactic means (syllabus for the teaching geometry, geometry exercises). These didactic creative models provide a field of study in which other aspects of didactic transposition may be examined concretely within a theory of contextual meaning. The contextual meaning attempts to describe the factors that determine a didactic situation. Teaching in itself or the concept to be taught must take place within a context from whence it derives its meaning and contextual significance. This is what is referred to as the concept "contextual meaning". The significant contribution of this dissertation will be its study of the effects of didactic transposition."

    Biographical Data: Manar Elhassan is trained and expert in Biostatistics and Epidemiology, awarded a PhD from Boston University (USA), an MSc in Statistics from University of Kent at Canterbury (UK) and a BSc in Statistics and Computer Science from University of Khartoum (Sudan).
    Here is the Abstract of her thesis: "This research addresses and compares tests for trend in proportions in ordinal categorical data in terms of robustness and power. Robustness is evaluated by comparing actual probabilities of rejecting a true hypothesis with specified nominal levels. Power, estimated as the actual probability of rejecting a false hypothesis, is compared among the tests considered. For a single contingency table data, the study compares the Mantel extension test, an exact conditional test, and Kendall's tau b asymptotic test when applied to small samples. The approach is based on exact calculations by complete enumeration of the sampling distributions from which actual significance levels are derived. The results show that the Mantel extension test is robust for the higher nominal levels 0.05 and 0.10, in that the actual significance levels do not seriously exceed the nominal levels. The Exact test is found to be conservative at all nominal levels. The study also shows that the power of Mantel extension test is always greater than the power of the Exact test. In addition, the results show Kendall's tau b test to be a liberal test and suggests the test to be inappropriate for small samples. For stratified data, a simulation study investigates the Mantel extension test, a trend test used in the Framingham Study, and the Wald test in a logistic regression, when applied to small and moderate samples. The approach is based on generating the empirical sampling distributions from which the actual probabilities of rejecting the hypothesis are estimated. The results demonstrate that the Mantel extension test is robust at all nominal levels, where the actual significance levels were always very close to the nominal levels. The Wald test performs similar to the Mantel extension test for the larger sample sizes and the larger nominal levels. The study also shows that the behaviour of the Framingham Study trend test depends on the hypothesis considered and on the sample size, although the actual significance levels were generally greater than the nominal levels. The power analysis shows that the power of the latter test is greater than that of Mantel extension test."

While there is ample reason to increasingly adopt a range of technologies to enhance the effectiveness of teaching and learning, the relationship between the adoption of technology and student success is less certain. The hype surrounding the adoption and inclusion of technologies in teaching is often lacking evidence that they actually increase student success. This article reports on the introduction and adoption rate of computer technology to enhance learning in the ODL environment. In 2008, an open source software tool, Maxima, was introduced in a Mathematical Modelling module in order to help students learn and understand mathematical skills applied to problem solving. Though the results show that the introduction of a compulsory assessment improves the adoption rate of the package, the link between technology adoption and student success is less certain. The article explores a number of reasons for the lack of evidence that the adoption of Maxima by students has not had any impact on their success. Based on the concept of technological pedagogical content knowledge, and the technology acceptance model, the article concludes with a reflection on strategies to ensure that the adoption of technology is integrated into the Mathematical Modelling curriculum in order to improve student throughput."

    Country: South Africa
    Year: 1995.
    Degree: Doctorat.
    Thesis title: Completeness and nearly fine uniform frames.
    University: Université Catholique de Louvain (Belgium).
    Advisors: Francis Borceux and C. Gilmour (South Africa).
    Biographical Data: She has worked at the University of Cape Town, South Africa, the University of Denver, Colorado, USA, and later at the Center for Excellence in Computation, Algebra, and Topology, Chapman University, Orange California, USA. Her Masters Thesis was Uniform sigma frames and the cozero part of uniform frames submitted to the University of Cape Town in 1989.
    She has published over 20 papers, the first being Compactifications and uniformities on sigma frames (1991) which appeared before her marriage under the name Joanna Walters, as did her Masters Thesis. In 2000 she published Cozfine and measurable uniform frames which has the following acknowledgement: "Most of this paper is part of the doctoral thesis written under Francis Borceux and Christopher Gilmour. I acknowledge scholarships from the Foundation for Research Development of South Africa and the University of Cape Town, and the support of the departments of Mathematics of the University of Cape Town and Universite Catholique de Louvain and the Topology and Category Theory Research Group at Cape Town." Although this paper appeared in 2000, it was first submitted in February 1997. Her later papers include A pointfree study of bases for spaces of minimal prime ideals (2003), Coz-onto frame maps and some applications (2007), The P-frame reflection of a completely regular frame (2011), and The Dedekind MacNeille site completion of a meet semilattice (2016).

  99. Jillian Beryl ADLER (née SMIDT)
    Country: South Africa
    Year: 1996.
    Degree: Ph.D.
    Thesis title: Secondary School Teachers' Knowledge of the Dynamics of Teaching and Learning mathematics in Multilingual Classrooms.
    University: University of the Witwatersrand (Johannesburg, South Africa).
    Biographical Data: She worked at the University of the Witwatersrand where she has advised at least four doctoral students. She published the book Teaching mathematics in multilingual classrooms in 2002. David Pimm writes in a Foreword: "In this book, Jill Adler has written an extensive account of her work exploring key dilemmas of secondary mathematics teachers' practice as they teach. She speaks with a strong 'I' voice, grounded in her practice as a researcher and much more, while at the same time lowering the ladder on the activity of research itself by careful and thoughtful commentary, with both her argument and rationale intentionally and explicitly presented. Adler focuses on three main dilemmas of multilingual mathematics teaching and learning and comments that "Teachers manage their dilemmas", adding also that "Every day, teachers in South Africa (and in many other countries), manage their mathematics teaching in multilingual settings."
    Adler writes: "First and foremost is my deep gratitude and respect for the mathematics teachers who are so central to this book. They welcomed me into their classrooms, gave generously of their time and participated in the research process openly, self-critically and with enthusiasm. I can only hope they benefited and were enriched by a process that undoubtedly enriched me. This book is the culmination of many years' work. As such, it has been shaped and influenced by many colleagues in the field as well as students in my graduate classes. I thank them all."
