These excerpts from Animal Farm are examples of the many instances in which mathematical ideas, especially those connected to number, are used in the book. The author used his ‘common’ knowledge of mathematics and his familiar language to present the story of Animal Farm using mathematical ideas explicitly or implicitly. It is possible that the author’s intentions were not to present mathematics or mathematical ideas, but because some storylines needed the use of mathematical language, he could not do so without using mathematics. This article emerges from a study that assessed learners’ abilities to interpret what they read and in particular, to ‘see’ mathematical aspects in the book Animal Farm. The study sought to find out learners’ abilities to read mathematically since mathematics is a specialised language that requires a specialised domain of practice. Animal Farm was one of the English Home Language literature books for high school learners in Grades 10–12 in South Africa in the 2015 academic year. According to the Department of Basic Education (2014), other novels for English Home Language were The Great Gatsby (Fitzgerald, 2008) and Pride and Prejudice (Austen, 2008). Learners were presented with excerpts from Animal Farm such as the ones quoted above. They were required to identify the mathematics part of the excerpts and to interpret what the excerpts meant. In the first excerpt, the mathematics part is ‘eighteen hands high’. According to conversion rates one adult hand is approximately 0.1016 m long. Therefore, Boxer’s height in metres was approximately 1.83 m. It was important for learners to understand this mathematical aspect in order to make sense of the extract. Without this understanding, the statement: ‘eighteen hands high’, does not make sense as one reads it in the printed media. Understanding what one is reading and how one needs to read is a critical skill required in relation to learning and achievement in education generally and mathematics education specifically.
《动物农场》中的这些摘录是书中使用数学思想的许多例子,尤其是那些与数字有关的思想。作者用他对数学的“常识”和他熟悉的语言,用明示或暗示的数学思想讲述了《动物农场》的故事。作者的意图可能不是为了展示数学或数学思想,但由于一些故事情节需要使用数学语言,他无法在不使用数学的情况下做到这一点。这篇文章来自一项研究,该研究评估了学习者解读所读内容的能力,尤其是“看到”《动物农场》一书中数学方面的能力。这项研究试图了解学习者的数学阅读能力,因为数学是一门需要专业实践领域的专业语言。《动物农场》是2015学年南非10-12年级高中生的英语家庭语言文学书籍之一。根据基础教育部(2014)的数据,其他英语家庭语言小说有《了不起的盖茨比》(Fitzgerald,2008)和《傲慢与偏见》(Austen,2008)。向学员展示了动物农场的摘录,如上文所述。他们被要求识别摘录中的数学部分,并解释摘录的含义。在第一段节选中,数学部分是“十八手高”。根据转换率,一只成年手的长度约为0.1016米。因此,Boxer的身高(米)约为1.83米。对于学习者来说,理解这一数学方面以理解摘录是很重要的。如果没有这种理解,“十八只手高”的说法在印刷媒体上读起来就没有意义。了解一个人在读什么以及需要如何阅读是一项关键技能,这与教育中的学习和成就有关,尤其是数学教育。

The growing perception of professional learning communities as an effective professional development approach needs to be supported with knowledge of how such communities create learning opportunities for teachers. Activities in professional learning communities are underpinned by collegial conversations that foster learning, and in this article we analysed such conversations for learning opportunities in one professional learning community of mathematics teachers. Data consisted of audio-recorded community conversations. The focus of the conversations was to understand the thinking behind learners’ errors, and teachers engaged in a number of activities related to learner errors and learner reasoning. Our analyses show how opportunities for learning were created in identifying the origins of learners’ errors as well as learners’ thinking underlying their errors. Results also showed that the teachers had opportunities for learning how to identify learners’ learning needs and in turn the teachers’ own learning needs. The teachers also had opportunities for deepening their own understanding of the conceptual meaning of ratio. The learning opportunities were supported by the following: having a learning focus, patterns of engagement that were characterised by facilitator questioning, teacher responses and explanations, and sharing knowledge. Such mutual engagement practices in professional learning communities resulted in new and shared meanings about teachers’ classroom practices. Our findings also show the critical role of a facilitator for teacher learning in professional learning communities.

Mathematics has been defined by researchers as a ‘second or third language’ and, as a result, it should be taught as a second language. Results of the literature reviewed from the theories on the teaching of mathematics and English as a second language, as well as on mathematics learning and English as a second language acquisition, have resulted in the emergence of four themes, which are similar to the ones on the teaching and learning of both mathematics and English as a second language; these are: comprehensible input, language processing and interaction, output, and feedback. In this article, the themes are illustrated in a theoretical model and discussed to show how English as a second language and mathematics can be acquired simultaneously. (English as a second language in the South African context is referred to as English as a first additional language.)
研究人员将数学定义为“第二或第三语言”,因此,数学应该作为第二语言来教授。从数学和英语作为第二语言的教学理论,以及数学学习和英语作为一种第二语言习得的理论来看,文献综述的结果导致了四个主题的出现,这四个主题与数学和英语都作为第二语文的教与学相似;这些是:可理解的输入、语言处理和交互、输出和反馈。在这篇文章中,这些主题在一个理论模型中得到了说明,并进行了讨论,以展示英语作为第二语言和数学是如何同时获得的。(在南非,英语作为第二语言被称为英语作为第一附加语言。)

Mathematical sense-making through learner choice 通过学习者选择建立数学意义
IF 1.2 Q3 Mathematics Pub Date : 2018-10-24 DOI: 10.4102/PYTHAGORAS.V39I1.424
Piera Biccard
Learners often view learning mathematics as non-sense-making (Dienes, 1971; Schoenfeld, 1991). Non-sense-making is distinct from nonsense (no meaning is possible) and is closer to the term senseless (having no meaning). Schoenfeld (1991, p. 316, 320) coined the phrase ‘suspension of sensemaking’ or ‘significant nonreason in students’ school mathematics’ to describe learners’ disengagement with mathematics. The senselessness experienced by learners when trying to engage with mathematics may stem from a disconnection between the learners’ procedural and conceptual understanding. Teachers also mistake procedural competency for conceptual understanding where they see the latter as a natural consequence of the former. Often the senselessness of mathematics comes from this assumption, especially when the problem changes from ‘basics’ (manipulation) to ‘application’ (word problems). Curricula are also often set up to mask procedural ability for conceptual understanding.
学习者通常认为学习数学是没有意义的(Dienes,1971;Schoenfeld,1991)。无意义的制造不同于无意义的(没有意义是可能的),更接近于无意义(没有意义)一词。Schoenfeld(1991,第316320页)创造了“感觉制造的暂停”或“学生学校数学中的显著非理性”这一短语来描述学习者对数学的脱离。学习者在尝试参与数学时所经历的无感可能源于学习者的程序理解和概念理解之间的脱节。教师还将程序能力误认为是概念理解,他们认为后者是前者的自然结果。数学的无意义往往来自于这种假设,尤其是当问题从“基础”(操作)变成“应用”(单词问题)时。课程设置也经常掩盖概念理解的程序能力。

After a long six-year lapse, the Curriculum and Assessment Policy Statement introduced in 2012 included geometry as part of the South African Grade 12 Mathematics Paper 2. The first cohort of matriculation students wrote Paper 2 in 2014. This article reports on the understanding of geometry terminology with which a group of 154 first-year mathematics education students entered a rural South African university in 2015; 126 volunteered to be part of the study. Responses to a 60-item multiple-choice questionnaire (30 verbally presented and 30 visually presented items) in geometry terminology provided the data for the study. A concept’s verbal description should be associated with its correct visual image. Van Hiele theory provided the lens for the study. An overall percentage mean score of 64% obtained in the test indicated that the majority of the students had a fairly good knowledge of basic geometry terminology. The students obtained a percentage mean score of 68% on visually presented items against that of 59% on verbally presented items implying a lower level thinking as per Van Hiele theory. The findings of this study imply a combination approach using visual and verbal representations to enhance conceptual understanding in geometry. This has to be complemented and supplemented through scaffolding to fill student teachers’ content gap.
在漫长的六年之后,2012年出台的课程和评估政策声明将几何作为南非12年级数学试卷2的一部分。2014年,第一批大学预科学生完成了第二篇论文。本文报道了2015年一组154名一年级数学教育学生进入南非一所农村大学时对几何术语的理解;126名志愿者参与了这项研究。对60项多项选择问卷(30项口头呈现,30项视觉呈现)的回答为研究提供了数据。一个概念的口头描述应该与其正确的视觉形象相关联。范·海尔理论为这项研究提供了视角。在测试中获得的总体百分比平均分数为64%,这表明大多数学生对基本的几何术语有相当好的了解。学生在视觉呈现项目上的平均得分为68%,而在口头呈现项目上的平均得分为59%,这意味着根据范·海尔理论,他们的思维水平较低。本研究的发现暗示了一种结合视觉和语言表征的方法来提高几何概念的理解。这需要通过脚手架来补充和补充,以填补学生教师的内容空白。

Affordances for learning linear functions: A comparative study of two textbooks from South Africa and Germany 学习线性函数的代价——南非和德国两本教科书的比较研究

Textbook content has the ability to influence mathematical learning. This study compares how linear functions are presented in two textbooks, one of South African and the other of German origin. These two textbooks are used in different language-based streams in a school in Gauteng, South Africa. A qualitative content analysis on how the topic of linear functions is presented in these two textbooks was done. The interplay between procedural and conceptual knowledge, the integration of the multiple representations of functions, and the links created to other mathematical content areas and the real world were considered. It was found that the German textbook included a higher percentage of content that promoted the development of conceptual knowledge. This was especially due to the level of cognitive demand of tasks included in the analysed textbook chapters. Also, while the South African textbook presented a wider range of opportunities to interact with the different representations of functions, the German textbook, on the other hand, included more links to the real world. Both textbooks linked ‘functions’ to other mathematical content areas, although the German textbook included a wider range of linked topics. It was concluded that learners from the two streams are thus exposed to different affordances to learn mathematics by their textbooks.
教材内容具有影响数学学习的能力。这项研究比较了两本教科书中线性函数的表现方式,一本是南非的,另一本是德国的。在南非豪登省的一所学校里,这两本教科书被用于不同的语言流。对这两本教材中线性函数的命题进行了定性的内容分析。考虑了程序知识和概念知识之间的相互作用,函数的多种表示的集成,以及与其他数学内容领域和现实世界之间的联系。研究发现,德国教科书中促进概念知识发展的内容比例更高。这尤其是由于所分析的教科书章节中包含的任务的认知需求水平。此外,虽然南非教科书提供了更广泛的机会来与不同的功能表示进行互动,但德国教科书则包含了与现实世界的更多联系。这两本教科书都将“函数”与其他数学内容领域联系起来,尽管德国教科书包含了更广泛的相关主题。因此,这两个流的学习者在学习数学时会接触到不同的可供性。

Awareness of one’s own strengths and weaknesses during visualisation is often initiated by the imagination – the faculty for intuitively visualising and modelling an object. Towards exploring the role of metacognitive awareness and imagination in facilitating visualisation in solving a mathematics task, four secondary schools in the North West province of South Africa were selected for instrumental case studies. Understanding how mathematical objects are modelled in the mind may explain the transfer of the mathematical ideas between metacognitive awareness and the rigour of the imaginer’s mental images. From each school, a top achiever in mathematics was invited to an individual interview (n = 4) and was video-recorded while solving a mathematics word problem. Participants also had to identify metacognitive statements from a sample of statement cards (n = 15) which provided them the necessary vocabulary to express their thinking during the interview. During their attempts, participants were asked questions about what they were thinking, what they did and why they did what they had done. Analysis with a priori coding suggests the three types of imagination consistent with the metacognitive awareness and visualisation include initiating, conceiving and transformative imaginations. These results indicate the tenets by which metacognitive awareness and visualisation are conceptually related with the imagination as a faculty of self-directedness. Based on these findings, a renewed understanding of the role of metacognition and imagination in mathematics tasks is revealed and discussed in terms of the tenets of metacognitive awareness and imagination. These tenets advance the rational debate about mathematics to promote a more imaginative mathematics.
在可视化过程中,对自己的长处和弱点的认识通常是由想象力发起的-直观地将物体可视化和建模的能力。为了探索元认知意识和想象力在促进可视化解决数学任务中的作用,南非西北省的四所中学被选中进行工具性案例研究。理解数学对象是如何在大脑中建模的,可以解释数学思想在元认知意识和想象者心理图像的严谨性之间的转移。每所学校邀请一名数学成绩最好的学生进行单独面试(n = 4),并在解决数学单词问题时进行录像。参与者还必须从陈述卡样本(n = 15)中识别元认知陈述,这为他们提供了必要的词汇来表达他们在面试过程中的想法。在他们的尝试过程中,参与者被问及他们在想什么,他们做了什么以及他们为什么这么做。先验编码分析表明,与元认知意识和视觉化相一致的三种想象类型包括启动想象、构思想象和转化想象。这些结果表明,元认知意识和可视化在概念上与想象作为一种自我指导的能力相关的原则。基于这些发现,本文从元认知意识和元想象的原则出发,揭示和讨论了元认知和想象在数学任务中的作用。这些原则推动了关于数学的理性辩论,促进了更具想象力的数学。
