Building leadership capacity in the development and sharing of mathematics learning resources, across disciplines, across universities

Porter, Anne L. 09 May 2012 (has links)
In this paper we examine an Australian project in which we seek to develop leadership capacity in staff and students throughout the country, such that they may contribute to and lead others to contribute to the development and sharing of learning support resources for mathematics and statistics across disciplines and universities. One of the tangible outputs is a set of video based learning support resources that can be embedded in subjects across disciplines and shared across institutions. However the guiding aim is to develop leadership capacity, in its simplest form leading others to lead others to contribute to the project. Leadership may also be developed and exercised across different aspects of the project whether it be mapping needs, drawing together disciplines groups, finding ways to recognise and reward those engaged in the process, developing resources and the associated skills, ensuring copyright adherence, creating learning designs for optimal use of resources, evaluating the impact on student outcomes, peer review and the dissemination of findings.

Rate as the relation of changes in two quantities : A variation theory perspective of learning rate of change

Håkansson, Per January 2020 (has links)
This thesis comprises three original papers about learning rate of change in school mathematics. The overall aim of the thesis is to contribute with knowledge in this particular area of research. Within this aim, each of the original papers contribute with its own perspective. The theoretical framework used in the thesis is variation theory of learning (Marton & Booth, 1997; Marton, 2015), by which learning is seen as experiencing a phenomenon in a new way. This theoretical point of departure is reflected in the research question of the thesis: What is critical to discern to use and express rate as a measure of the relation of changes in two quantities? The empirical study was conducted as a learning study (Pang & Marton, 2003). A learning study is an iterative, interventional research arrangement in which teachers and researchers collaboratively explore a specific ability, the object of learning, worthwhile for the students to learn. The object of learning related to this thesis, ‘to express the quantitative rate of change of a linear relation’, was explored in a series of three research lessons at a secondary school. Data consists of students’ responses to written pre- and post-tests, and lesson videos. Some data have been analysed during the on-going empirical study and some data have been analysed after it was concluded. Principles from variation theory have been used as tools for analysis throughout the study. Main results of Paper I demonstrate how two critical aspects are identified and revised through the process of learning study. In Paper II the results indicate that qualitatively different questions in a task may affect students’ ways to relate changes in two quantities. The results of Paper III suggest how different perspectives of slope may promote homogeneity as an aspect of rate. Results also comprise six critical aspects of the object of learning, four of which was identified by revisiting the results of Paper II. In summary, the critical aspects also specify the meaning of a covariational perspective of rate. Results are discussed in relation to previous educational research about rate of change, covariation of quantities and students’ conceptions of rate and slope. Further research directions are suggested. / Den här sammanläggningsuppsatsen omfattar tre artiklar om förändringstakt i matematik. Uppsatsens övergripande syfte är att bidra med kunskap till detta specifika forskningsfält. Inom ramen för detta syfte bidrar var och en av de tre artiklarna med sitt eget perspektiv. Det teoretiska ramverket i uppsatsen är variationsteori (Marton & Booth, 1997; Marton, 2015). Ur detta teoretiska perspektiv ses lärande som ett erfarande av ett fenomen på ett nytt sätt. Denna teoretiska utgångspunkt har färgat uppsatsens övergripande forskningsfråga: Vad är kritiskt att urskilja för att använda och uttrycka förändringstakt somett mått på relationen mellan förändringar i två storheter? Den empiriska studien genomfördes som en learning study (Pang et al., 2003). Learning study är en iterativ, intervenerande forskningsansats där lärare och forskare i samarbete utforskar en specifik förmåga, lärandeobjektet, något som är värdefullt för elever att lära sig. Lärandeobjektet som behandlas i denna uppsats, ’att uttrycka förändringstakten i en linjär relation kvantitativt’, utforskades i en serie av tre lektioner på en högstadieskola. Data består av elevers svar till skriftliga uppgifter i för- och eftertest, samt videoinspelade lektioner. Data har analyserats både under den pågående empiriska studien, och efter att den avslutades. Principer från variationsteori har använts som analysverktyg genom studiens gång. Huvudresultaten av Artikel I visar hur två kritiska aspekter identifieras, revideras och förfinas genom learning study som process. I Artikel II tyder resultaten på att kvalitativt olika frågor i en uppgift påverkade elevernas sätt att relatera förändringar i två storheter. Resultaten i Artikel III visar hur olika perspektiv på lutningen hos en graf kan föra fram homogenitet som en aspekt av förändringstakt. Uppsatsens resultat omfattar framför allt sex aspekter som är kritiska att urskilja för att utveckla förmågan att använda och uttrycka förändringstakt som ett mått på relationen mellan förändringar i två storheter. Fyra av dem identifierades då resultaten av Artikel II tolkades utifrån ett variationsteoretiskt perspektiv. Som helhet specificerar också de kritiska aspekterna innebörden av ett samvarierande perspektiv på förändringstakt. Resultaten diskuteras i förhållande till tidigare forskning om lärande om förändringstakt, samvariation mellan storheter och elevers uppfattningar av lutning. Några vidare forskningsriktningar pekas ut.

Sobre alteridade, autonomia, autoridade e saberes docentes nas aulas de matemática / On alterity, autonomy, authority and teacher knowledge in Mathematics classes

Jesus, Humberto Luis de 29 May 2018 (has links)
A atividade do docente que ensina matemática, se compreendida como uma prática social, pode ser estudada tendo como suporte referenciais teóricos e metodológicos de abordagens sociológicas. O objetivo do estudo foi identificar, analisar e discutir elementos constitutivos da atividade docente relacionados aos saberes, à autoridade, à autonomia e à alteridade, manifestados em processos de interação durante a resolução de problemas em aulas de matemática. Trata-se de uma pesquisa qualitativa orientada pelas ações de quatro professoras, participantes da pesquisa, que lecionam matemática nos anos iniciais de uma escola municipal de ensino fundamental situada na zona sul da cidade de São Paulo. Os dados empíricos foram produzidos entre junho de 2016 e novembro de 2017 a partir de fontes e procedimentos diversificados: a) encontros de formação continuada de matemática coordenados pelo pesquisador, ocorridos na própria escola; b) planejamentos de aulas de matemática feitos pelas quatro professoras; c) interações ocorridas entre os alunos e entre estes e as professoras no desenvolvimento das aulas planejadas; d) acompanhamento das aulas pelo investigador. A interpretação e análise dos dados reunidos por meio de questionários, produção escrita, mensagens eletrônicas e observações de aula apoiaram-se em procedimentos metodológicos da Sociologia Pragmática e embasamentos teóricos relativos às políticas públicas de educação e de formação de professores, à resolução de problemas, à comunicação e à interação nas aulas de matemática e aos saberes, à alteridade, à autonomia e à autoridade docentes. Os resultados dessa análise confirmaram: (i) a hipótese da pesquisa de que as quatro professoras mobilizaram, além de saberes disciplinares, curriculares e experienciais relativos ao ensino e à aprendizagem de matemática, aspectos relativos à alteridade, autonomia e autoridade docentes nos processos interativos estabelecidos entre elas e os alunos; (ii) a necessidade de refletir e problematizar os impactos de políticas públicas de formação, inicial e continuada de professores, que desconsideram a condição docente, o papel e a importância do professor na explicitação do que consiste a natureza do seu trabalho. As análises sugerem a defesa de políticas públicas educacionais que dignifiquem tanto a condição quanto o papel do professor da escola básica, convocando-o para o debate e a participação direta na formulação destas políticas, não o concebendo somente como mero executor de ações decididas por atores sociais externos ao seu contexto de trabalho. / Mathematics teaching activity, if understood as a social practice, can be investigated having as a support specific theoretical and methodological references of sociological approaches. The aim of this study was to identify, analyze, and discuss constitutive elements of teaching activity related to acquirements, alterity, autonomy, and authority expressed in interacting processes during problem solving in Mathematics classes. It is a qualitative research guided by four teachers actions; these teachers, subjects of the research, teach Mathematics in the first years of a community basic school located in South of São Paulo. Empirical data have been generated between June 2016 and November 2017 from different sources and procedures: a) continued formation meetings on Mathematics coordinated by the researcher, which took place at the school itself; b) Mathematics classes planning made by above-mentioned four teachers; c) interactions occurring between students and between them and above-mentioned teachers in developing planned classes; d) resort to questionnaires, written production, e-mails, class monitoring and records. Data interpretation and analysis were based on methodological procedures from Pragmatic Sociology and theoretical foundations related to public policies on education and teacher formation, problem solving, communication and interaction in Mathematics classes, and to teachers acquirements, alterity, autonomy, and authority. This analysis led us to the following results: (i) they confirmed the research hypothesis that besides disciplinary, curriculum, and experimental acquirements related to Mathematics teaching and learning these four teachers mobilized aspects related to teachers alterity, autonomy, and authority in the interactive processes established between them and their students; (ii) they confirmed the need to reflect upon and question the impacts of initial and continued teachers formation public policies that disregard teaching condition and teachers role and importance in making explicit the nature of their work. The analyses suggest one should support educational public policies that promote both teachers condition and role in basic schools, calling them in for a debate and a direct involvement in shaping these policies, instead of framing them only as mere executors of actions decided by social actors external to their work environment.

This paper had as a general objective to look for evidence of validity of assessment and intervention tools related to mathematics anxiety and to this end, the research was divided into two studies. The study part is intended to search for evidence of validity of the Mathematics Anxiety Scale (MAS). It is divided into three steps aiming in order to investigate the main objectives such as verify evidence of the inner structure of the MAS; check out correlations between high and low scores on the MAS and school performance in subject matters like mathematics, portuguese, history and geography; expand the application of the MAS in the South, Midwest and Northeast in Brazil and observe possible differences in average scores of mathematics anxiety in each region, taking into account students’ gender, school year (grades) and term. The second study aimed to verify the effectiveness of an intervention program to math anxiety and it was done in a single step. On the first study, the results in step 1, by Exploratory and Confirmatory Data Analysis, indicated that the MAS tends to show a structure with two dimensions. In part 2, the results showed that there was significant and positive correlation between MAS total score and performance in mathematics, in eleven two-month terms analyzed; Portuguese, in six two-month terms; History; in twomonth terms; Geography, in six two-month terms. In the third part, the results showed significant difference in MAS average in relation to the gender variable in the Midwest, southern regions and in the general sample. Referring to the period variable, there was also a significant difference in the Midwest, Southeast and also, in the general sample. On the school year variable, the significant differences in MAS average occurred in the Midwest and in the general sample. In the Midwest, the significant differences in MAS scores occurred between the 1st year of high school (9th grade) and the 6th and 7th years of elementary school. Significant differences were also observed between the 3rd grade and the 8th grade; the 6th grade and 8th and 1st grades; the 7th grade and 1st and 8th grades; and the 8th grade and 3rd, 6th and 7th grades. In the general sample, the differences between the 1st grade of high school (9th grade) and the 6th and 7th grades of elementary school. In relation to the general objective of this paper which is about the search for evidence of validity of an assessment tool and the effectiveness of an intervention, both concerned with math anxiety, data supporting positive evidence for carrying on using MAS and to the intervention were found in this research. Although the last one was only an initial study and thus it is still not possible to indicate whether it is effective, but the results are promising. / A ansiedade à matemática é caracterizada por um conjunto específico de reações fisiológicas desagradáveis, cognitivas e comportamentais diante de qualquer estímulo matemático ou contingências de aprendizagem de matemática. Esse trabalho teve como objetivo geral buscar evidências de validade de ferramentas de avaliação e intervenção relacionadas à ansiedade à matemática e para isso o trabalho foi dividido em dois estudos. O primeiro estudo é a busca de evidências de validade da Escala da Ansiedade à Matemática – EAM – dividida em três etapas para a investigação dos respectivos objetivos específicos: verificar evidências da estrutura interna da EAM; verificar correlações entre altos e baixos escores na escala EAM e desempenho escolar nas disciplinas de matemática, português, história e geografia; ampliar a aplicação da EAM na região Sul, Centro-Oeste e Nordeste e observar possíveis diferenças de média de escores de ansiedade à matemática em cada região, considerando as variáveis gênero, ano escolar e período. O segundo estudo teve como objetivo verificar a eficácia de um programa de intervenção de ansiedade à matemática e abrangeu apenas uma etapa. Sobre o primeiro estudo, os resultados na etapa 1 por meio da Análise Fatorial Exploratória e Confirmatória, indicaram que o instrumento EAM tende a apresentar uma estrutura com duas dimensões. Na etapa 2, os resultados mostraram que houve correlação significativa e positiva entre escore total da EAM e desempenho em: matemática, em onze bimestres analisados; português, em seis bimestres; história; em dois bimestres; geografia, em seis bimestres. Na terceira etapa, os resultados apontaram diferença significativa de média na EAM, em relação à variável gênero nas regiões Centro-Oeste, Sul e na amostra geral. Referente à variável período, também houve diferença significativa quando analisadas as regiões Centro-Oeste, Sudeste e também, na amostra geral; sobre a variável série, as diferenças significativas na média. da EAM ocorreram na região Centro-Oeste e na amostra geral. Na região Centro-Oeste as diferenças significativas na pontuação da EAM ocorreram entre o 1º ano do Ensino Médio e o 6º e 7º anos do Ensino Fundamental. Também foram observadas diferenças significativas entre o 3º ano e o 8º ano; o 6º ano e 8º e 1º anos; o 7º ano e 1º e 8º anos; e o 8º ano e 3º, 6º e 7º anos; na amostra geral as diferenças entre o 1º ano do Ensino Médio e a 6º e 7º anos do Ensino Fundamental. Em relação ao objetivo geral do estudo, sobre a busca de evidências de validade para um instrumento de avaliação e da eficácia de uma intervenção, ambos para ansiedade à matemática, na presente pesquisa foram encontrados dados que sustentam evidências positivas para a continuação dos estudos com a EAM e para a intervenção, embora esse último tenha sido apenas um estudo inicial e por isso, ainda não é possível indicar se possui eficácia, mas os resultados são favoráveis.

OPEN-ENDED APPROACH TO TEACHING AND LEARNING OF HIGHSCHOOL MATHEMATICS

Mahlobo, Radley Kebarapetse 07 May 2012 (has links)
The author shares some of the findings of the research he conducted in 2007 on grade 11 mathematics learners in two schools, one experimental and the other one control. In his study, the author claims that an open-ended approach towards teaching and learning of mathematics enhances understanding of mathematics by the learners. The outcomes of the study can be summarised as follows: 1. In the experimental school, where the author intervened by introducing an open-ended approach to teaching mathematics (by means of giving the learners an open-ended approach compliant worksheet to work on throughout the intervention period), the performance of the learners in the post-test was better than that of the learners from the control school. Both schools were of similar performance in the pre-test. The two schools wrote the same pre-test and same post-test. Both schools were following common work schedule. 2. Within the experimental school, post-test performance of the learners in the class where the intervention was monitored throughout the intervention period (thus ensuring compliance of the teacher to the open-ended approach) out-performed those in which monitoring was less frequent. 3. There was no significant difference in performance between learners from the unmonitored experimental class and those from the control class.

Diálogos com professoras que ensinam matemática em início de carreira / Dialogos with math teachers in career home

Kronbauer, Cíntia Fogliatto 28 September 2016 (has links)
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior - CAPES / This work is the product of an investigation that is part of the LP1: Research, Training, Knowledge and Professional Development Line of the Graduate Program in Education of the Federal University of Santa Maria / RS, focused on broadening the discussions in The initial training of teachers of mathematics and their first years of teaching. The aim of this research is to identify the constituent elements of the initial formation of teachers of mathematics that contribute to the first years of teaching, verifying the approximation and distances of the initial formation course and the reality experienced in the schools, through the gaze of the beginning teacher who teaches mathematics. The research theme came from the experience of the researcher as a teacher who teaches mathematics in her early years of teaching, given the emergence of problems, challenges, uncertainties and difficulties to be faced in the classroom, and that often the beginner teacher Is not prepared to face them. The theoretical references that base this writing that refer to the initial formation are Charlot (2000), Tardif (2002), Mizukami (2006), Imbérnon (2011), Vaillant; Garcia (2012), in the initial formation of teachers of mathematics are Ponte (1998), Moura (2001, 2002), Libâneo (2004), Lorenzato (2010), among others. In relation to the first years of teaching, the main references were Huberman (1992), Garcia (2009), Vaillant and Tardif (2002). For that, the investigation was carried out with teachers who teach mathematics in the state public network of the municipality of Ijuí / RS, the dialogue was recorded and occurred through semistructured interviews with seven teachers. Through their narratives we have been able to know them from the choice of the mathematics course, the first ones counted with the teaching in the initial formation and the entrance in the teaching career. With the transcribed dialogue the interpretation and understanding of the data was based on the narrative analysis of Galvão (2005) with the contribution of the hermeneutic experience, for understanding to happen, Gadamer (1997) argues that the interpreter moves from a projected meaning of the whole to the parts, and then returns to the whole, Called by the author of the hermeneutic circle, in this way the knowledge of the completeness of the text allows the interpreter to question between what is not familiar and what is being shared. The results allow us to share that the teachers understand that initial training is a necessary support for future practices, motivating and encouraging future teachers to think about mathematics teaching, however, during the training, there were difficult situations in the stages that marked The identity of these teachers. They concluded that the entry into the career was a moment of expectation but that feelings of insecurity, uncertainty, fears were greater and emphasized that the main deficiency in this initial period was in the organization of pedagogical practice and that the lack of support is Remarkable, end up resorting to experienced teachers. We conclude that the initial training course left some gaps strongly felt by the teachers at the beginning of the career, so they understand that the training course needs to provide more classroom practices, believe that they learn in practice, and could thus face with greater Clarity in classroom situations. / Este trabalho é produto de uma investigação que insere-se na LP1: Linha de Pesquisa Formação, Saberes e Desenvolvimento Profissional, do Programa de Pós-graduação em Educação da Universidade Federal de Santa Maria/RS, tem seu foco voltado a ampliação das discussões no âmbito da formação inicial de professores que ensinam matemática e seus primeiros anos de atuação docente. O objetivo desta pesquisa é identificar elementos constituintes da formação inicial de professores que ensinam matemática que contribuem para os primeiros anos da docência, verificando a aproximação e os distanciamentos do curso de formação inicial e a realidade vivenciada nas escolas, através do olhar do professor iniciante que ensina matemática. A temática da investigação surgiu a partir da vivência da pesquisadora como professora que ensina matemática em seus primeiros anos de atuação docente, visto o surgimento de problemas, desafios, incertezas e dificuldades a serem enfrentadas em sala de aula, e que muitas vezes o professor principiante não está preparado para enfrentá-los. O referenciais teóricos que embasaram esta escrita que referem-se a formação inicial são Charlot (2000), Tardif (2002), Mizukami (2006), Imbérnon (2011), Vaillant; Garcia (2012), na formação inicial de professores que ensinam matemática são Ponte (1998), Moura (2001; 2002), Libâneo (2004), Lorenzato (2010), dentre outros. Em relação aos primeiros anos de atuação docente os principais referenciais foram Huberman (1992), Garcia (2009), Vaillant e Tardif (2002). Para tanto, a investigação foi realizada com professores que ensinam matemática na rede pública estadual do município de Ijuí/RS, o diálogo foi gravado e ocorreu através de entrevistas semiestruturadas com sete professoras. Através das suas narrativas pudemos conhecê-las desde a escolha pelo curso de matemática, os primeiros contados com a docência na formação inicial e a entrada na carreira docente. Com o diálogo transcrito a interpretação e compreensão dos dados baseou-se na análise narrativa de Galvão (2005) com a contribuição da experiência hermenêutica, para que a compreensão aconteça, Gadamer (1997) argumenta que o intérprete se move de um significado projetado do todo para as partes, e então volta para o todo, denominado pelo autor de círculo hermenêutico, dessa forma o conhecimento da completude do texto permite que o intérprete questione entre aquilo que não lhe é familiar e o que está sendo compartilhado. Os resultados nos permitem compartilhar que as professoras entendem que a formação inicial é um suporte necessário para as futuras práticas, motivando e incentivando os futuros professores a pensar o ensino de matemática, no entanto, durante a formação, nos estágios houveram situações difíceis o que marcou a identidade dessas professoras. Completam que a entrada na carreira, foi um momento de expectativas, mas que os sentimentos de insegurança, incertezas, medos, foram maiores e enfatizaram que a principal deficiência, nesse período inicial, foi na organização da prática pedagógica e que a falta de apoio é notável, acabam recorrendo aos professores experientes. Concluímos que o curso de formação inicial deixou algumas lacunas fortemente sentidas pelas professoras na entrada na carreira, assim, elas entendem que o curso de formação precisa fornecer mais práticas em sala de aula, acreditam que aprendem na prática, sendo assim, poderiam enfrentar com maior clareza as situações em sala de aula.
