In South Africa, limited studies have been conducted investigating responsive teaching and little is known about how teachers respond to unexpected events ‘in the moment’ that did not form part of their planning. In this article, we report how a Grade 9 novice and expert teacher responded to unexpected learner offers during the teaching of algebra using a qualitative case study approach. Three consecutive lessons for each teacher were video recorded, transcribed and analysed. Our units of analysis for episodes were teachers’ responses to unexpected learner offers and we coded the responses as ‘appropriate’ or ‘inappropriate’. Indicators used to highlight the degree of quality of the response were ‘minimum’, ‘middle’ and ‘maximum’ if a response was coded as appropriate to a learner’s offer. Once lessons were analysed, the first author conducted video-stimulated recall interviews with each participant to gain insight into the two teachers’ thoughts and decision-making when responding to unexpected learner offers. The findings from this study illustrated that the novice teacher failed to press learners when their thinking was unclear, chose to ignore or provided an incorrect answer when faced with an unexpected learner offer. Conversely, the expert teacher continuously interrogated learner offers by pressing if a learner offer was unclear or if she wanted learners to explain their thinking. This suggests that the expert teacher’s responses were highly supportive of emergent mathematics learning in the collective classroom space.
在南非,对响应式教学进行的研究有限,对教师如何应对“当下”未纳入其计划的意外事件知之甚少。在这篇文章中,我们报道了一位九年级的新手和专家教师如何在代数教学中使用定性案例研究方法来应对意外的学习机会。每名教师连续三节课都进行了录像、转录和分析。我们对事件的分析单位是教师对意外的学习者提供的回应,我们将这些回应编码为“合适”或“不合适”。如果回应被编码为适合学习者的提议,则用于强调回应质量程度的指标为“最低”、“中等”和“最高”。分析完课程后,第一作者对每位参与者进行了视频刺激的回忆访谈,以深入了解两位老师在回应意外的学习者邀请时的想法和决策。这项研究的结果表明,当学习者的思维不清楚时,新手教师没有强迫他们,当面对意外的学习机会时,他们选择忽略或提供了错误的答案。相反,如果学习者的提议不明确,或者她是否希望学习者解释他们的想法,专家教师会不断追问学习者的建议。这表明,专家教师的反应高度支持在集体课堂空间中进行紧急数学学习。

Constructing mental diagrams during problem-solving in mathematics 在数学问题解决过程中构建心理图

In mathematics, problem-solving can be considered to be one of the most important skills students need to develop, because it allows them to deal with increasingly intricate mathematical and real-life issues. Often, teachers attempt to try to link a problem with a drawn diagram or picture. Despite these diagrams, whether given or constructed, the student still individually engages in a private discourse about the problem and its solution. These discourses are strongly influenced by their a priori knowledge and the given information in the problem itself. This article explores first-year pre-service teachers’ mental problem-solving skills. The emphasis was not on whether they solved the problems, but rather on their natural instincts during the problem-solving process. The research shows that some students were naturally drawn to construct mental images during the problem-solving process while others were content to simply leave the question blank. The data were collected from 35 first-year volunteer students attending a second semester geometry module. The data were collected using task sheets on Google Forms and interviews, which were based on responses to the questions. An interpretive qualitative analysis was conducted in order to produce deeper meaning (insight). The findings point to the fact that teachers could try to influence how students think during the problem-solving process by encouraging them to engage with mental images.
在数学中,解决问题可以被认为是学生需要培养的最重要的技能之一,因为它使他们能够处理日益复杂的数学和现实生活中的问题。通常,老师们会试图将问题与绘制的图表或图片联系起来。尽管有这些图表,无论是给定的还是构建的,学生仍然单独地参与到关于问题及其解决方案的私人讨论中。这些话语受到他们的先验知识和问题本身的给定信息的强烈影响。本文探讨了第一年职前教师的心理问题解决能力。重点不在于他们是否解决了问题,而在于他们在解决问题过程中的本能。研究表明,一些学生在解决问题的过程中自然地被吸引去构建心理图像,而另一些学生则满足于简单地让问题空白。这些数据是从参加第二学期几何模块的35名一年级志愿者中收集的。数据是通过谷歌表单上的任务表和访谈收集的,这些任务表是基于对问题的回答。为了产生更深刻的意义(洞察力),进行了解释性定性分析。研究结果指出,教师可以通过鼓励学生参与心理图像来影响他们在解决问题过程中的思维方式。

This study, using a quantitative approach, examined Spanish and South African pre-service teachers’ responses to translating word problems based on direct proportionality into equations. The participants were 79 South African and 211 Spanish prospective primary school teachers who were in their second year of a Bachelor of Education degree. The study’s general objective was to compare the students’ proficiency in expressing direct proportionality word problems as equations, with a particular focus on the extent of the reversal error among the students’ responses. Furthermore, the study sought to test the explanatory power of word order matching and the static comparison as causes of the reversal error in the two contexts. The study found that South African students had a higher proportion of correct responses across all the items. While nearly all the errors made by Spanish students were reversals, the South African group barely committed reversal errors. However, a subgroup of the South African students made errors consisting of equations that do not make sense in the situation, suggesting that they had poor foundational knowledge of the multiplicative comparison relation and did not understand the functioning of the algebraic language. The study also found that the word order matching strategy has some explanatory power for the reversal error in both contexts. However, the static comparison strategy offers explanatory power only in the Spanish context, suggesting that there may be a difference in curriculum and instructional approaches in the middle and secondary years of schooling, which is when equations are taught.
本研究采用定量方法,考察了西班牙和南非职前教师对将基于直接比例的单词问题翻译成等式的反应。参与者是79名南非和211名西班牙的准小学教师,他们正在攻读教育学士学位的第二年。这项研究的总体目标是比较学生将直接比例词问题表达为方程的熟练程度,特别关注学生回答中反向误差的程度。此外,本研究试图检验语序匹配和静态比较作为两种语境中反转错误原因的解释力。研究发现,南非学生在所有项目中的正确回答比例较高。虽然西班牙学生犯下的几乎所有错误都是逆转,但南非学生几乎没有犯下逆转错误。然而,一组南非学生犯了错误,这些错误由在这种情况下没有意义的方程组成,这表明他们对乘法比较关系的基础知识很差,也不理解代数语言的功能。研究还发现,语序匹配策略对两种语境中的反转错误都有一定的解释力。然而,静态比较策略仅在西班牙背景下提供解释力,这表明在中学和中学教育中,课程和教学方法可能存在差异,而中学和中学是教授方程式的时候。

The coronavirus disease 2019 (COVID-19) pandemic and the resulting school closures in South Africa necessitated a major shift in how to support learners’ ongoing mathematics learning. For 10 weeks learners were strictly confined to their homes with restrictions that prohibited seeing any person outside of their household. The only means to access learners and parents in their homes was to reimagine our South African Numeracy Chair Project work and transform it from predominantly face-to-face interventions to digital modalities. As a result, we initiated a project of digital resource development and distribution, particularly focused on our local community in the Eastern Cape. Twenty-two existing resources and 36 purpose-designed resources were shared via Facebook. Through in-depth post hoc reflection of the rapid digitalisation of our materials and ways of working we address these questions: (1) In relation to learners’ new ‘ecology of learning’ during lockdown what digital access modality and platforms were most fit-for-purpose in sharing mathematics learning resources? (2) What principles informed resource design and adaptation for digital distribution and use? (3) What dilemmas were confronted in making decisions about resource design and distribution?. These questions are answered through a document review and post hoc reflections on the noted dilemmas. We share some feedback received and discuss implications of our work and the dilemmas confronted for the provision of quality digital resources for supporting mathematics learning in historically disadvantaged and under-resourced communities in a post pandemic world.
2019冠状病毒病(新冠肺炎)大流行以及由此导致的南非学校关闭,需要在如何支持学习者持续数学学习方面进行重大转变。在10周的时间里,学习者被严格限制在家里,并受到限制,禁止与家人以外的任何人见面。在家里接触学习者和家长的唯一方法是重新构想我们的南非算术主席项目工作,并将其从主要的面对面干预转变为数字模式。因此,我们启动了一个数字资源开发和分配项目,特别关注东开普省的当地社区。通过脸书共享了22个现有资源和36个专门设计的资源。通过对我们的材料和工作方式的快速数字化进行深入的事后反思,我们解决了以下问题:(1)关于封锁期间学习者的新“学习生态”,什么样的数字访问模式和平台最适合共享数学学习资源?(2) 哪些原则为数字分发和使用的资源设计和调整提供了依据?(3) 在做出资源设计和分配的决策时面临哪些困境?。这些问题是通过文件审查和对所指出的困境的事后反思来回答的。我们分享了收到的一些反馈,并讨论了我们工作的影响,以及在疫情后的世界中,为支持历史上处于不利地位和资源不足的社区的数学学习而提供优质数字资源所面临的困境。

Grade 9 learners’ understanding of fraction concepts: Equality of fractions, numerator and denominator 九年级学生对分数概念的理解:分数、分子和分母相等

Our research with Grade 9 learners at a school in Soweto was conducted to explore learners’ understanding of fundamental fraction concepts used in applications required at that level of schooling. The study was based on the theory of constructivism in a bid to understand whether learners’ transition from whole numbers to rational numbers enabled them to deal with the more complex concept of fractions. A qualitative case study approach was followed. A test was administered to 40 learners. Based on their written responses, eight learners were purposefully selected for an interview. The findings revealed that learners’ definitions of fraction were neither complete nor precise. Particularly pertinent were challenges related to the concept of equivalent fractions that include fraction elements, namely the numerator and denominator in the phase of rational number. These gaps in understanding may have originated in the early stages of schooling when learners first conceptualised fractions during the late concrete learning phase. For this reason, we suggest a developmental intervention using physical manipulatives to promote understanding of fractions before inductively guiding learners to construct algorithms and transition to the more abstract applications of fractions required in Grade 9.
我们对索韦托一所学校九年级的学生进行了研究,以探索学生对该级别学校所需应用程序中使用的基本分数概念的理解。这项研究基于建构主义理论,旨在了解学习者从整数到有理数的转变是否使他们能够处理更复杂的分数概念。采用了定性案例研究方法。对40名学习者进行了测试。根据他们的书面回答,有目的地选择了八名学习者进行面试。研究结果表明,学习者对分数的定义既不完整也不准确。特别相关的是与包括分数元素的等价分数概念有关的挑战,即有理数阶段的分子和分母。这些理解上的差距可能起源于学校教育的早期阶段,当时学习者在后期的具体学习阶段首次将分数概念化。因此,我们建议在归纳指导学习者构建算法并过渡到9年级所需的更抽象的分数应用程序之前,使用物理操纵器进行发展干预,以促进对分数的理解。

Design principles to consider when student teachers are expected to learn mathematical modelling 学生教师学习数学建模时要考虑的设计原则
IF 1.2 Q3 Mathematics Pub Date : 2021-09-29 DOI: 10.4102/pythagoras.v42i1.618

This article sets out design principles to consider when student mathematics teachers are expected to learn mathematical modelling during their formal education. Blum and Leiß’s modelling cycle provided the theoretical framework to explain the modelling process. Learning to teach mathematical modelling, and learning to solve modelling tasks, while simultaneously fostering positive attitudes, is not easy to achieve. The inclusion of real-life examples and applications is regarded as an essential component in mathematics curricula worldwide, but it largely depends on mathematics teachers who are well prepared to teach modelling. The cyclic process of design-based research was implemented to identify key elements that ought to be considered when mathematical modelling is incorporated in formal education. Fifty-five third-year student teachers from a public university in South Africa participated in the study. Three phases were implemented, focusing firstly on relevance (guided by a needs analysis), secondly on consistency and practicality via the design and implementation of two iterations, and lastly on effectiveness by means of reflective analysis and evaluation. Mixed data were collected via a selection of qualitative instruments, and the Attitudes Towards Mathematical Modelling Inventory. Through content analyses students’ progress was monitored. Results analysed through SPSS showed significant positive changes in their enjoyment and motivation towards mathematical modelling. Student teachers require sufficient resources and opportunities through their formal education to participate regularly in mathematical modelling activities, to develop competence in solving modelling tasks, and to augment positive attitudes. This study adds value to the global discussion related to teachers’ professional development regarding mathematical modelling.
本文提出了学生数学教师在正式教育期间学习数学建模时应考虑的设计原则。Blum和Leiß的建模周期为解释建模过程提供了理论框架。学习数学建模和解决建模任务,同时培养积极的态度,并不容易实现。包括真实的例子和应用程序被视为世界各地数学课程的一个重要组成部分,但这在很大程度上取决于数学教师是否做好了教授建模的准备。实施了基于设计的研究的循环过程,以确定将数学建模纳入正规教育时应考虑的关键因素。来自南非一所公立大学的五十五名三年级学生教师参与了这项研究。实施了三个阶段,首先关注相关性(以需求分析为指导),其次通过两次迭代的设计和实施关注一致性和实用性,最后通过反思性分析和评估关注有效性。混合数据是通过一些定性工具和对数学建模的态度清单收集的。通过内容分析,监控学生的学习进度。通过SPSS分析的结果显示,他们对数学建模的兴趣和动机发生了显著的积极变化。学生教师需要通过正规教育获得足够的资源和机会,定期参加数学建模活动,培养解决建模任务的能力,并增强积极的态度。这项研究为有关教师数学建模专业发展的全球讨论增加了价值。

The coronavirus disease 2019 (COVID-19) pandemic supported an investigation of ongoing challenges as to whether and how to make mathematics relevant to learners’ lifeworlds. Given that COVID-19 created major disruptions in all learners’ lives, we developed and taught tasks that attempted to make links between their experiences of the pandemic and disciplinary mathematical knowledge. We located our investigation in current debates about the extent to which disciplinary knowledge can be linked to learners’ out-of-school experiences. We developed and analysed two tasks about COVID-19 that could support link-making and productive disciplinary engagement, and analysed one Grade 10 teacher teaching these tasks. We found that linking mathematics to learners’ lifeworlds is both possible and extremely difficult in relation to task design and how the teacher mediates the tasks. In relation to task design, we argue that teachers cannot do it alone;they need to be supported by the curriculum and textbooks. In relation to mediation, we saw that teacher practices are difficult to shift, even in the best of circumstances. We articulate the complexities and nuances involved in bridging powerful knowledge and lived experience and thus contribute to debates on how to teach powerful knowledge in relation to learners’ lifeworlds.
2019年冠状病毒病(COVID-19)大流行支持了一项关于是否以及如何使数学与学习者的生活世界相关的持续挑战的调查。鉴于COVID-19对所有学习者的生活造成了重大干扰,我们开发并教授了一些任务,试图将他们的大流行经历与学科数学知识联系起来。我们的调查定位于当前关于学科知识与学习者校外经历之间的联系程度的争论。我们制定并分析了两项关于COVID-19的任务,这些任务可以支持建立联系和富有成效的学科参与,并分析了一位10年级教师教授这些任务的情况。我们发现,在任务设计和教师如何协调任务方面,将数学与学习者的生活世界联系起来既是可能的,也是极其困难的。关于任务设计,我们认为教师不能单独完成任务设计,他们需要课程和教科书的支持。关于冥想,我们看到,即使在最好的情况下,教师的做法也很难改变。我们阐明了连接强大的知识和生活经验所涉及的复杂性和细微差别,从而有助于讨论如何教授与学习者的生活世界相关的强大知识。

Flexible teaching of mathematics word problems is essential to improve learning. Flexible teaching is vital in terms of providing meaningful learning, creating inclusive learning spaces and making content accessible. As such, teachers need to strive to provide flexible teaching of mathematics word problems in order to optimise and maximise learning. In line with this notion, therefore, the qualitative case study reported in this article aimed to explore the implementation of one aspect of universal design for learning (UDL), namely multiple means of representation (MMR), to guide flexible teaching of mathematics word problems. Data were collected using focus group discussions, reflection and observation sessions in which five high school mathematics teachers and a Head of Department were involved. The teachers participated in a mini-workshop on the application of the UDL principles which was organised to introduce and induct them to the approach. The study showed that MMR can be used to help guide flexible teaching of mathematics word problems by providing varied options for comprehension: options for language, mathematical expressions and symbols, as well as options for perception. The findings of the study recommend the need for teachers to adapt their teaching by considering the application of the MMR principle to guide and promote flexible teaching of mathematics word problems.
灵活的数学单词问题教学对提高学习效果至关重要。灵活的教学对于提供有意义的学习、创造包容性的学习空间和提供内容至关重要。因此,教师需要努力提供灵活的数学单词问题教学,以优化和最大限度地提高学习效果。因此,根据这一概念,本文报道的定性案例研究旨在探索通用学习设计(UDL)的一个方面,即多重表示方法(MMR)的实施,以指导数学单词问题的灵活教学。数据是通过焦点小组讨论、反思和观察会议收集的,五名高中数学教师和一名系主任参与了这些会议。教师们参加了一个关于UDL原则应用的小型研讨会,该研讨会旨在向他们介绍和引导这种方法。研究表明,MMR可以通过提供各种理解选项来帮助指导数学单词问题的灵活教学:语言、数学表达式和符号的选项,以及感知的选项。研究结果表明,教师有必要通过应用MMR原则来指导和促进数学单词问题的灵活教学来调整教学。
