An investigation into understanding the experiences of the level 5-7 student teachers when teaching fractions in primary schools in Namibia: a case study

Vatilifa, Ndamononghenda January 2013 (has links)
The Namibian government through the Ministry of Education seeks for teachers to meet the demands and rise to the challenges of the post-independence basic education system. Therefore the University of Namibia Education Faculty must ensure through the training of student teachers for both lower, upper primary and secondary school level that these demands are met. Research shows that one of the major challenges in teacher training programs, specifically in the mathematics education programmes, lies with the student teachers’ difficulties in dealing with various topics in mathematics, particularly fractions. The teaching of fractions is a challenging area at primary level and lays the foundation for understanding different topics in upper grades such as algebra, ratio and proportion, statistics and probability, to mention just a few. This study focused on an exploration of teaching fractions by five student teachers during their teaching practice.The main purpose was to gain an understanding of the experiences of the level 5-7 student teachers with regard to their practice of fraction teaching; their experience of the mathematics education course with respect to the teaching of fractions; and their prior experience related to fractions and fraction teaching at Grade 6 level. The findings from this research showed that student teachers viewed mathematics, specifically fractions, as just about doing calculations, doing drill and practice as in this way learners’ understanding of fractions is enhanced. The importance of using rules and procedures was emphasized as paving the way to mastering fractions. The data analysis also revealed that student teachers employed different teaching approaches when they considered learners’ prior knowledge. However, they misinterpreted the learner-centred approach in terms of group work and class discussion in their teaching of fractions. The data also revealed that some student teachers had an understanding of fractions as they managed to redirect their learners from applying some fraction misconceptions. The findings further showed that due to lack of understanding most of the participants experienced fear and anxiety in their fraction teaching; attempted an approach then reverted to old practices used in schools; taught fractions as symbolic representations where no meaning was involved; used incorrect terminologies such as ‘1 over 4’ or ‘1 out of 4’ instead of a ‘quarter’ or ‘one-fourth’. It is further revealed that the some student teachers viewed a fraction as a pair of two different whole numbers and can be broken apart. The findings of this study yielded one main implication for the teaching of mathematics: that the teacher training programs, specifically for mathematics teachers, must take into consideration the weaknesses and strengths of the student teachers shown in this study to properly train and prepare them to become effective mathematics teachers.

A critical investigation into the process of negotiating a mathematics education curriculum with pre-service teachers

Westaway, Lise January 2005 (has links)
It's almost like a dinner party and a buffet. A dinner party you get dished up stuff and you eat it and a buffet you can choose what you want out of a range of stuff. I mean think about it when you go to a dinner party- they always dish up something you don't like and you don't want to eat it anyway. It's the same if you have a lecturer in the front that just dishes out what you're going to learn, ... you have to learn it. But in terms of the curriculum negotiation process, I've got to choose what I wanted to leam. (Melissa II 27/11/01: 3) This thesis focuses on the process of negotiating the curriculum with twelve pre-service teachers registered for the Bachelor of Education (Primary) Degree during their Mathematics Education Course in their third year of study. The research is presented methodologically as an action research located within two paradigmatic positions, interpretive and critical. The research attempted to understand, interpret and critique the process of curriculum negotiation within the context of teacher education in South Africa In order to understand the negotiated curriculum process, experiences of the participants are presented through the use of their voices within the thesis. The interpretation is based on the construction and reconstruction of meaning during the enactment of the negotiated curriculum process and during the writing and reviewing of this thesis. The critique is rooted in the historical, cultural and social contexts of both the students and the author. The main contention of this thesis is that curriculum negotiation is not necessarily a suitable vehicle for developing a critical pedagogy in pre-service teacher education when all the participants form a homogenous group in this case, white middle-class women. The democratic values promoted within the context of our curriculum negotiation were fraught with dilemmas and entrenched the values of western liberalism. At most, the curriculum negotiation process and the development of a democratic learning environment, promoted a conscientisation at an individual level, namely a ' transformation of consciousness' . The democratic values promoted in our pedagogy were not sufficient in bringing about social change, a 'transformation for social action'.

An investigation into the pre-service training of secondary school mathematics teachers at colleges of education administered by the House of Representatives

Hendricks, Mogamat Armien January 1989 (has links)
This study involves an investigatioh into the nature and effectiveness of the pre-service training, where provided, of secondary school Mathematics teachers at the 11 colleges of education administered by the House of Representatives in the Republic of South Africa. The purpose of this study is to determine whether the HDE (Secondary) course offered at some of the aforementioned colleges of education is justified, In spite of the fact that it contravenes the requirements of the Education Act, No. 73 of 1969. Three different questionnaires were designed and during 1986 were sent to heads of Mathematics departments at the aforementioned colleges of education , to Mathematics teacher educators at these colleges and to beginning secondary school Mathematics teachers, teaching at schools administered by the House of Representatives in the Eastern Cape and Natal. The findings of this study show that the secondary course for Mathematics teachers is only offered at 5 of the 11 colleges of education and only a small percentage of students take this course. During 1986 most of the Mathematics teacher educators at the colleges of education were not suitably qualified. The study also shows that the Mathematics curriculum for the training of secondary school teachers is inadequate and a revision thereof is thus recommended. An obvious conclusion drawn from the findings is that the training of secondary school Mathematics teachers at these colleges of education is still in an early stage of development. One of the main recommendations of this study is that the training of secondary school Mathematics teachers at colleges of education administered by the House of Representatives should be terminated , in view of its ineffectiveness and In accordance with Education Act , No . 73 of 1969. On the other hand, in case this is not possible, suggestions are also made for the improvement of the pre-service training of secondary school mathematics teachers at these colleges of education.

Esta tem como pergunta diretriz "O que enunciaram e apresentaram os professores participantes de um curso de formação continuada sobre o uso das Tecnologias Digitais em aulas de Educação Básica?". Os sujeitos da pesquisa foram professores da rede pública estadual pertencente à Diretoria de Ensino de São José do Rio Preto, que participaram de um curso de formação continuada voltado para uso de tecnologias no ensino de Geometria. Os resultados apresentados mostram que os professores veem como importante o uso das Tecnologias Digitais durante suas aulas de Geometria, principalmente devido às potencialidades que os softwares de Geometria Dinâmica proporcionam, como a visualização, investigação e experimentação. No entanto destaca-se a necessidade de uma formação específica para o uso das tecnologias, principalmente direcionada para a elaboração das atividades e aponta alguns fatores que podem influenciar na maneira como o professor concebe e utiliza as tecnologias em suas aulas, tais como, a falta de apoio da gestão escolar, a insegurança gerada devido a falta de formação e a falta da infraestrutura das salas de informáticas. / Grounded in the qualitative methodology approach, this study investigated the conceptions of Basic Education Mathematics teachers regarding to Digital Technologies (DT), in Middle School. This research has as leading question “What did the teachers participating in an in-service teacher training course enunciate and present about the use of Digital Technologies in Basic Education classes?”. The investigation subjects were state public school teachers belonging to the Board of Teaching of São José do Rio Preto, who participated in an in-service teacher training course focused on the use of technologies in Geometry teaching. The presented results show that the teachers see as important the use of Digital Technologies in his Geometry classes, mainly because of the potentialities that the Dynamic Geometry softwares provides, as visualization, investigation and experimentation. However, it stands out the necessity of a specific training to the use of technologies, specially directed at the elaboration of tasks and it suggests some factors that can influence on the way that the teacher conceives and employs the technologies in his classes, such as, the lack of support of the school management, the insecurity caused by the lack of training, and, the lack of infrastructure in the computer labs.

Congruências e polinômios: uma aplicação

Pissarék, Clóvis João 05 December 2014 (has links)
CAPES / Este trabalho tem como objetivo aprofundar o conhecimento dos professores do ensino médio fundamental a respeito de congruência e polinômios. Apesar de congruência não ser abordado nas escolas, este assunto justifica alguns conceitos repassados aos alunos, como por exemplo a divisibilidade de um número por outro. A congruência ainda pode auxiliar na verificação de raízes de polinômios. Aqui, os polinômios são tratados como elementos de um anel, o anel dos polinômios, e vários resultados utilizados em sala de aula são justificados a partir da estrutura desse anel. Com esses dois conceitos, ainda e feito um breve estudo de congruência polinomial. / The aim of this work is to deepen the knowledge of elementary and high school teachers about congruence and polynomials. Although congruence is not studied in schools, this subject justifies some concepts passed to the students, such as the divisibility of one number by another. The congruence can also help to verify roots of polynomials. Here, polynomials are treated as elements of a ring, the ring of polynomials, and several results used in the classroom are justified from the structure of this ring. These concepts are used for a brief study of polynomial congruence.

A análise combinatória e seu ensino

Miotto, Eder 29 September 2014 (has links)
CAPES / O presente trabalho tem dois objetivos: o primeiro está relacionado ao ensino da análise combinatória nas séries do ensino fundamental 2 e ensino médio. O segundo objetivo e buscar aprofundar meus conhecimentos relacionados aos conceitos combinatoriais. Com relação ao primeiro objetivo, o ensino da análise combinatória, na minha trajetória como docente, tem sido uma das tarefas mais árduas que o professor de matemática da educação básica enfrenta. Diante disso, surgem algumas perguntas. Por que um assunto totalmente aplicável ao cotidiano tem gerado tanta dificuldade de compreensão? Um dos objetivos desse trabalho e buscar respostas para essa pergunta e propor sugestões que possam melhorar o entendimento desse conceito. Como segundo objetivo proposto, busquei compreender conceitos que até então, por mim, não dominados, aprofundando meu conhecimento combinatorial. Para tanto, esse trabalho possui uma parte dedicada ao estudo de conceitos combinatorias mais complexos, não o abordados junto aos alunos de ensino médio mas que permitem compreender situações combinatoriais mais complexas. / The present work has two major goals. The first one is related to the teaching of combinatorics in elementary school and high school. The second one is to seek further knowledge related to combinatorial concepts. Regarding the first goal, the teaching of combinatorics, in my trajectory as a teacher, has been one of the most arduous tasks that the math teacher of basic education faces. Therefore, some questions arise. Why a subject fully applicable to everyday, has generated so much trouble understanding? One of the goals of this work is to seek answers to this question and propose suggestions that can improve the understanding of this concept. As a second proposed goal, I sought to understand concepts that hitherto were not dominated, deepening my combinatorial knowledge. Therefore, this work has section devoted to the study of more complex combinatory concepts, not addressed to the students of high school but they allow us to understand more complex combinatorial situations.

Exploring teaching proficiency in geometry of selected effective mathematics teachers in Namibia

Stephanus, Gervasius Hivengwa January 2014 (has links)
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.
