This study aimed to determine the quality elements of flexible learning to be used as basis for the development of a quality assured module and instructional videos in Data Management of Mathematics ...in the Modern World subject. It also investigated experiences in flexible learning, the quality elements, strengths, and weaknesses of the developed learning module and video recorded lectures, and the challenges encountered by mathematics teachers and students in flexible learning. This study utilized a mixed method of research design. Results showed that there are challenges and difficulties that need to be addressed because these might be the factors that hamper the attainment of quality of flexible learning beyond face-to-face learning. Further, the developed learning module and video-recorded lectures were much valid and much acceptable. However, there were identified strengths and weaknesses of the materials which were the bases in improving the materials to produce a quality assured module and instructional videos in Data Management. It is recommended that researchers study the implementation of flexible learning to the mathematics program and other programs in the curriculum and discover solutions to the challenges that might be encountered by the teachers and students in its implementation. The improvement of the quality of education through program enhancement could be achieved through this.
•There are six levels of knowledge within each of the reasoning processes.•The three upper levels have an inclusive relation due to their comprehensive nature.•Prospective teachers need to develop ...specialised knowledge of reasoning processes.
The development of mathematical reasoning is part of the school curricula from the first years, as reflected in teacher education. This study focuses on the prospective primary teachers education, aiming to construct a framework which describes the knowledge about mathematical reasoning processes of teachers and prospective teachers, in the context of a prospective teacher education experiment. Audio and video records of lessons, participant observation and the collection of written records of the prospective teachers are used. The results enable the construction of a framework organised into six levels of knowledge within each of the reasoning processes looked at – generalising, justifying, comparing, classifying and exemplifying – in order to analyse the evolution of this type of knowledge.
Resumo Neste artigo apresenta-se um estudo sobre construção de escalas, com base na Teoria da Resposta ao Item (TRI), para medir proficiência em conteúdos matemáticos básicos, necessários ao ...acompanhamento das disciplinas de Cálculo e similares, de ingressantes em cursos da área de Ciências Exatas. Adotou-se o modelo logístico unidimensional de três parâmetros, que estabelece média zero e desvio padrão 1, para as proficiências dos indivíduos. As proficiências estimadas foram transformadas em outra escala, optando-se por valores adotados por sistemas de avaliação brasileiros, a saber, 250 e 50. O instrumento de medida consistiu em uma prova com 36 itens, de cinco alternativas, somente uma correta, elaborados com base em uma matriz de referência, dividida em três temas, “Espaço e Forma”, “Grandezas e Medidas” e “Números e Operações, Álgebra e Funções”. Cada tema é composto por competências, que descrevem as habilidades que se deseja medir. Para a construção da escala foram especificados níveis de proficiência, representando pontos selecionados pelos pesquisadores para serem interpretados pedagogicamente. Estabelecidos os níveis âncora, foram definidos os itens âncora, a partir de critérios, como, por exemplo, o número de acertos, os percentuais de acertos e a diferença entre seus valores, para níveis consecutivos. Com base nestes critérios, comparou-se três métodos de posicionamento dos itens, mostrando as dificuldades de interpretação em pontos da escala. Tais dificuldades oportunizaram a propositura de outro método, segmentando a escala em faixas de proficiência, com base em agrupamentos hierárquicos dos níveis, o que permitiu a interpretação da escala em toda a sua amplitude.
•Mathematical reasoning is an important feature in the learning of mathematics.•Many primary teachers unclear about the term ‘mathematical reasoning’.•Teaching mathematics to develop mathematical ...reasoning is challenging.•Phenomenographic analysis and development of outcome space (OS) is explained.•OS demonstrates range of teachers’ perceptions of mathematical reasoning.•OS provides framework for track development of mathematical reasoning.
Mathematical reasoning has been emphasised as one of the key proficiencies for mathematics in the Australian curriculum since 2011 and in the Canadian curriculum since 2007. This study explores primary teachers’ perceptions of mathematical reasoning at a time of further curriculum change. Twenty-four primary teachers from Canada and Australia were interviewed after engagement in the first stage of the Mathematical Reasoning Professional Learning Program incorporating demonstration lessons focused on reasoning conducted in their schools. Phenomenographic analysis of interview transcripts exploring variation in the perceptions of mathematical reasoning held by these teachers revealed seven categories of description based on four dimensions of variation. The categories delineate the different perceptions of mathematical reasoning expressed by the participants of this study. The resulting outcome space establishes a framework that facilitates tracking of growth in primary teachers’ awareness of aspects of mathematical reasoning.
