The education sector, among others, was severely affected by the coronavirus disease 2019 (COVID-19) pandemic. Because mathematics has always been singled out as a subject that needs more verbal communication and interaction, rapid adjustments had to be made by mathematics lecturers in higher education institutions to try and facilitate normal teaching and learning remotely through emergency open distance methods. Lecturers were forced to examine prevailing practices with a view to creating innovative and workable solutions to the emergency challenges without compromising the quality previously experienced during face-to-face classroom interactions. The article developed through a simple technology a conceptual framework for emergency remote teaching (ERT) in an emergency techno-response pedagogy (ETRP). The key was to demonstrate an innovative instructional strategy for teaching mathematics using a simple technology instead of an advanced or complicated mathematics software in the move from face-to-face to fully online teaching during a crisis. A development qualitative virtual case study was conducted that involved observing live and recorded mathematics lectures and interviewing an innovative lecturer of mathematics in the delivery of complex numbers at a graduate school in South Africa. The facilitation of the lesson through a simple and inexpensive technology (Microsoft OneNote) guided the development of a conceptual framework for ERT within an ETRP. The Context, Input, Process, and Product (CIPP) evaluation model was used as a theoretical framework to guide the analysis and conceptualisation of the lessons. Results provided guidelines through a conceptual framework for ERT that included a unique model of a lesson plan and advantages of using a simple technology in ERT instead of advanced mathematical software. The article contributes to the knowledge base in planning future ERT interventions.
除其他外,教育部门受到2019年冠状病毒病(COVID-19)大流行的严重影响。由于数学一直被认为是一门需要更多语言交流和互动的学科,高等教育机构的数学讲师不得不迅速做出调整,尝试通过紧急开放远程方式促进正常的远程教学。讲师被迫审查现行做法,以期在不影响以往面对面课堂互动质量的情况下,为紧急挑战创造创新和可行的解决办法。本文通过一种简单的技术,提出了应急技术响应教学法(ETRP)中应急远程教学的概念框架。关键是展示一种创新的教学策略,在危机期间从面对面教学转向完全在线教学,使用简单的技术而不是先进或复杂的数学软件来教授数学。进行了一项发展定性虚拟案例研究,其中包括观察现场和记录的数学讲座,并采访了一位在南非一所研究生院讲授复数的创新数学讲师。通过一种简单而廉价的技术(微软OneNote)促进了课程的发展,指导了ETRP中ERT概念框架的发展。情境、输入、过程和产品(CIPP)评价模型被用作指导课程分析和概念化的理论框架。结果通过一个概念框架为ERT提供了指导方针,其中包括一个独特的课程计划模型和在ERT中使用简单技术而不是高级数学软件的优势。本文为规划未来的ERT干预措施提供了知识库。

Mathematics education remains problematic in South Africa’s schools. However, some mathematics educators are deliberately using learners’ home languages in tasks to assist learners to understand mathematics. Research-based evidence shows that learners’ home languages when used as a resource have a potential to enhance learners’ understanding of mathematics. This article addresses the issue of translating mathematics tasks from English to learners’ home languages, a field that is less common in mathematics education studies. The study shows that there are complexities associated with such translation which all stakeholders in education should bear in mind. The article does so by referring to a study where a Grade 11 mathematics educator in a multilingual class tried to use learners’ home languages in tasks with an aim to enhance learners’ understanding of linear programming concepts. The study was conducted in township school in Gauteng province. Ethical clearance was given by the Gauteng Department of Education. Data were collected through observations and were analysed qualitatively. The situated sociocultural perspectives guided the study. The findings show that during the translation process, the educator went as far as translating mathematics technical terms. Such translation distorted the meaning of the original task and therefore made it hard for learners to comprehend concepts as envisioned. The recommendation is that the translation should not be left to individual mathematics educators but rather there should be a broader approach of having mathematics tasks translated from English into other official languages and such tasks be distributed to all schools throughout the country. Professional translators must also be contracted to do such a job.

Interpreting phenomena under uncertainty stands as a substantial cognitive activity in our daily life. Furthermore, in probability education research, there is a need for developing a unified model that involves several probabilistic conceptions. From this aspect, a central inquiry has been raised through this study: how do preservice mathematics teachers (PSMTs) reason under uncertainty? A multiple case study design was operated in which a purposive sample of PSMTs was selected to justify their reasoning in two probabilistic contexts while their responses were coded by NVivo, and corresponding categories were developed. As a result, PSMTs’ probabilistic reasoning was classified into mathematical (M), subjective (S), and outcome-oriented (O). Besides, several biases emerged along with these modes of reasoning. While M thinkers shared equiprobability and insensitivity to prior probability, the prediction bias and the belief of Allah’s willingness were yielded among S thinkers. Also, the causal conception spread among O thinkers.
在不确定性下解释现象是我们日常生活中一项重要的认知活动。此外,在概率教育研究中,需要建立一个包含多个概率概念的统一模型。在此基础上,本研究提出了一个核心问题:职前数学教师在不确定性下如何进行推理?在多案例研究设计中,我们选择了一个有目的的psmt样本来证明他们在两种概率背景下的推理,而他们的回答由NVivo编码,并形成相应的类别。结果表明,psmt的概率推理可分为数学型(M)、主观性(S)和结果导向型(O)三种类型,并存在一定的偏差。M个思考者具有等概率和对先验概率不敏感的特征,而S个思考者具有预测偏差和相信安拉意愿的特征。此外,因果概念在O思想家中传播。

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
IF 1.2 Q4 EDUCATION, SCIENTIFIC DISCIPLINES Pub Date : 2021-11-29 DOI: 10.4102/pythagoras.v42i1.633

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。
