An exploration of mathematical literacy teachers' perceptions of, and performance in mathematical literacy tasks based on algebra.

Vilakazi, Aubrey Sifiso. January 2010 (has links)
Mathematical Literacy (ML) has only recently been introduced to learners, and research in South Africa concerning learners’ conceptual understanding in ML is not widely available. However an important predictor of learners’ success or difficulties in concepts is the success or difficulties that in-service teachers experience themselves. It is therefore important for us as mathematics educators to identify areas in Mathematical Literacy that teachers are struggling to learn and apply. With this in mind, the study sets to explore teachers’ perceptions about, and performance in Mathematical Literacy tasks based on algebraic concepts. This study is located within the principles of the qualitative research case study approach. The combination of data collection techniques has allowed me to identify broad trends across the group as a whole as well as differences within the participants of the group itself. The participants of the study were a class of 17 students who were completing the ACEML programme at UKZN. Four sources of data were used. Firstly, data was generated from teachers’ reflections about certain tasks, the solution of which required the use of algebra. A second data collection instrument was an open-form questionnaire and the third instrument was two unstructured interviews with two teachers. The final instrument was the analysis of the teachers’ examination scripts. For this study, teachers from this group were classified along the lines of whether they were qualified to teach mathematics or not. The theoretical framework for the study was derived from the OECD/PISA (2003) cycle of mathematisation which specifies 5 aspects of mathematisation, together with the theory of reification. For the purpose of this research, a participant was considered as a “mathematics specialist” if s/he studied mathematics up to tertiary level, while a participant was considered as “non-mathematics teacher” if s/he studied mathematics only up to Grade 12 level. The findings reveal that although the teachers conveyed varying understandings of the ML curriculum, they believed that knowledge of basic algebra was necessary and adequate for them to deal with ML problems. Furthermore the teachers believed mathematical teaching experience contributes to improved problem solving in ML and that ‘practice and familiarity’ helped teachers improve their problem solving skills in ML. They also voiced a concern that the pace of the programme constituted a barrier to their success. Within the group, it was found that Mathematics specialist teachers performed better than the non-Mathematics teachers. All teachers found the mathematisation aspects of solving the mathematical problem and of reinterpreting the mathematical solution to make sense of the real-life problems, challenging, while the non-Mathematics teachers experienced problems with all five aspects of mathematisation. The findings of the study suggest that teachers need help in moving from lower levels to higher levels of mathematisation. Opportunities for mathematical modeling experiences need to be incorporated in the part-time in-service contact courses like ACEML. Further research is needed to inform education authorities about whether the use of teachers with only grade 12 mathematical knowledge to teach ML is advisable. / Thesis (M.Ed.)-University of KwaZulu-Natal, Edgewood, 2010.

Academic standards alignment with essential work skills : perceptions from Indiana guidance counselors and employers

Fassett, David R. January 2006 (has links)
The purpose of this exploratory study was to look at the importance of Indiana's Algebra I academic standards in relationship with essential, entry-level work skills as perceived by employers and guidance counselors in northern and northeastern Indiana. Counselors and employers were sent electronic (e-mail and web-based) or hard (paper) copies of a survey instrument. Section II of the survey asked for demographic data, (age, race, gender) as well as information related to the size of the business or school, type of business, and years in current position. Respondents were also asked to rate their knowledge of the Indiana academic standards, the Americans with disabilities Act and Section 504 of the Vocational Rehabilitation Act. In Section III, respondents were presented with the nine Indiana Algebra I standards, along with examples to illustrate and further explain each standard. Employers rated each standard, and the standards combined, on its importance to skills required from people seeking jobs immediately after leaving high school using a Likert scale. Guidance counselors rated the importance of the standards based on what they knew of the labor market within school district and surrounding areas using the same Likert scale. Comments were solicited at the end of the survey instruments. Employers disagreed with the importance of any of the Algebra I standards, or the standards as whole, as entry-level work skills. Their highest mean rating was 2.4. Counselors also disagreed, although on two standards their mean rating was above the Neutral rating. Sample size was deemed too low for generalization, but study does supply a framework for future research. / Department of Special Education

Perceived experiences that grade seven learners have in learning algebra.

Matsolo, Matjala Lydia January 2006 (has links)
<p>This thesis investigates grade seven learners perceived experiences in learning algebra.Things that learners do and say during algebra lessons and about algebra were investigated. The study was done at one of the previously disadvantaged schools in Cape Town, South Africa.The data were collected through observations, a questionnaire and interviews. Observations were made from the day the topic was started in two grade seven classes. Two different teachers taught the two classes. Focus group interviews were conducted, two group of learners, ten learners from each of the two classes were interviewed. Learners devised a number of strategies for solving problems related to sums and differences. The principal learning difficulties experienced by learners in algebra related to the transition from arithmetic conventions to those of algebra, the meaning of literal symbols and the recoginition of structures. It became obvious then that developing algebraic thinking is not necessarily dependent upon algebraic notation and that the presence of algebraic notation says little about the level of problem solving.</p>

An analysis of the influence of question design on pupils' approaches to number pattern generalisation tasks

Samson, Duncan Alistair January 2008 (has links)
This study is based on a qualitative investigation framed within an interpretive paradigm, and aims to investigate the extent to which question design affects the solution strategies adopted by children when solving linear number pattern generalisation tasks presented in pictorial and numeric contexts. The research tool comprised a series of 22 pencil and paper exercises based on linear generalisation tasks set in both numeric and 2-dimensional pictorial contexts. The responses to these linear generalisation questions were classified by means of stage descriptors as well as stage modifiers. The method or strategy adopted was carefully analysed and classified into one of seven categories. A meta-analysis focused on the formula derived for the nth term in conjunction with its justification. The process of justification proved to be a critical factor in being able to accurately interpret the origin of the sub-structure evident in many of these responses. From a theoretical perspective, the central role of justification/proof within the context of this study is seen as communication of mathematical understanding, and the process of justification/proof proved to be highly successful in providing a window of understanding into each pupil’s cognitive reasoning. The results of this study strongly support the notion that question design can play a critical role in influencing pupils’ choice of strategy and level of attainment when solving pattern generalisation tasks. Furthermore, this study identified a diverse range of visually motivated strategies and mechanisms of visualisation. An awareness and appreciation for such a diversity of visualisation strategies, as well as an understanding of the importance of appropriate question design, has direct pedagogical application within the context of the mathematics classroom.

No. of bitstreams: 1 Fernandes_FernandoLuisPereira_M.pdf: 1983189 bytes, checksum: de4eccc8b6aef9d80acef45634dab44f (MD5) Previous issue date: 2011 / Resumo: O objetivo principal desta pesquisa foi compreender como se dá o desenvolvimento do letramento algébrico de alunos do sétimo ano do Ensino Fundamental de uma escola pública no interior do estado de São Paulo. Foram escolhidas duas classes, nas quais eu era o professor responsável. Trata-se de uma pesquisa sobre a própria prática desenvolvida em um ambiente exploratório-investigativo, de natureza qualitativa, sobretudo interpretativa. A coleta de dados contou com a participação de uma auxiliar de pesquisa. O material de campo foi constituído pelo diário de campo do pesquisador e narrativas produzidas pela auxiliar de pesquisa, relatórios e cartazes produzidos pelos alunos e gravações em áudio e vídeo, sendo algumas delas transcritas. Como categorias de análise, temos (i) a mediação realizada pelo professor em diferentes momentos das aulas, dando atenção especial ao momento de socialização/sistematização das apresentações no processo de letramento algébrico; (ii) a constituição de um letramento algébrico, tendo como foco de análise e interpretação as crenças, valores e saberes mobilizados pelos alunos e a produção de sentidos e a negociação de significados desenvolvidas por eles durante a atividade investigativa e a socialização/sistematização de suas produções. Podemos afirmar a aprendizagem não se restringiu às tarefas contempladas. Além de os alunos se apropriarem de um modo de produzir sentido e estabelecer relação com a atividade algébrica, concebida como prática social de leitura e escrita de textos que mobilizam signos próprios da álgebra, também se apropriaram do modo de relacionar-se com o conhecimento matemático, mediante a uma dinâmica exploratório-investigativa. / Abstract: The main objective of this research was to understand how the literacy development of students in algebraic seventh year of elementary school of the public school in the state of Sao Paulo. Two classes were chosen, in which I was the teacher. This is a survey about their own practice developed in an exploratory environment, investigative, qualitative, interpretive above. Data collection included the participation of a research assistant. The field material was created by the diary of the narratives produced by the researcher and research assistant, reports and posters produced by students and in audio and video recordings and some of them transcribed. As categories of analysis, we have (i) mediation carried out by teacher at different times of the classes, giving special attention to the moment of socialization / systematization of the presentations in the literacy process algebraic, (ii) to establish an algebraic literacy, focusing on analysis and interpretation of the beliefs, values and knowledge mobilized by the students and the production of meaning and negotiation of meanings carried by them during the research activity and socialization / systematization of their productions. We affirm the learning was not restricted to tasks covered. Besides the students take ownership of a way to produce meaning and establish relationship with the algebraic activity, conceived as a social practice of reading and writing texts that mobilize themselves signs of algebra, also seized on the way to relate with mathematical knowledge, through a exploratory-investigatory dynamic. / Mestrado / Ensino e Práticas Culturais / Mestre em Educação

Operationalizing Listening-to-Question and Questioning-to-Listen in Mathematics Teaching

Kuehnert, Eloise Aniag 08 1900 (has links)
This study focused on the evaluative listening practices of four teachers who participated in an algebra professional development involving lesson study. This instrumental case study operationalizes the enactment of teacher listening followed by teacher questions and responses to define listening-to-question. Also, questioning-to-listen is operationalized as the enactment of purposefully posing questions to posture oneself to listen to students' mathematical thinking. Because of the tacit aspect of teacher listening and the visibility of teacher questioning, interrelating listening and questioning affords teachers an accessible point of entry into developing listening practices. In response to participants wondering as to when evaluative listening is appropriate in the mathematics classroom, this study discusses six instances of teaching excerpts along a continuum of listening orientations from directive to observational to responsive. The results indicate positive aspects of evaluative listening towards an observational and responsive listening stance. Results of the study also confirm a reliance on low-order gathering information questions as the predominant type of teacher question posed in mathematics teaching. This study reveals the necessity of contextualizing teacher questions to inform appropriate uses of evaluative listening. Future professional development should consider emphasizing positive aspects of evaluative listening in mathematics teaching.

The use of certain visual aids in the teaching of algebra

Unknown Date (has links)
"The problem of this study was to test the hypothesis that the use of certain visual aids will improve instruction in algebra. Two experiments were devised. In the first simple balance scales were used and in the second models were used. The experimenter also wished to learn through the testing of this hypothesis how to conduct such a study"--Introduction. / Typescript. / "August, 1950." / "Submitted to the Graduate Council of Florida State University in partial fulfillment of the requirements of the degree of Master of Arts." / Advisor: H.
