Recent publications emphasize the need to take greater account of differences in teaching quality between subjects. The empirical analysis of this topic requires a comparison of teaching quality in different subjects to distinguish generic aspects of teaching quality from subject-specific ones. In this paper, we compare teaching quality in mathematics and German lessons using observational data from primary schools in Switzerland (NMath = 319; NGerman = 237). Data were collected using an observation instrument reflecting the teaching dimensions of the MAIN-TEACH model, which was developed based on a synthesis of established observation frameworks. The dimensions of classroom management, motivational-emotional support, selection and implementation of content, cognitive activation, support for consolidation, assessment and feedback, and adaptation were tested for subject-related measurement invariance. With a two-fold measurement invariance approach, differences between the subjects were investigated at both a global and an indicator level. When applying alpha accumulation correction, no significant subject-related differences in factor loadings or intercepts were found. The factorial structure of our data was basically identical for the two subjects. The comparison of latent factor means revealed no mean differences between the subjects. We discuss the implications for both the MAIN-TEACH model and research into subject-related differences of teaching in general.

最近的出版物强调,有必要更多地考虑不同学科之间教学质量的差异。要对这一问题进行实证分析,就必须对不同学科的教学质量进行比较,以区分教学质量的一般方面和特定学科的教学质量。在本文中,我们利用来自瑞士小学的观察数据,对数学课和德语课的教学质量进行了比较(数学课 = 319;德语课 = 237)。数据收集使用了反映 MAIN-TEACH 模型教学维度的观察工具,该工具是在综合已有观察框架的基础上开发的。对课堂管理、动机-情感支持、内容的选择和实施、认知激活、巩固支持、评估和反馈以及适应等维度进行了与学科相关的测量不变量测试。采用双重测量不变性方法,从总体和指标两个层面研究了受试者之间的差异。在进行阿尔法累积校正时,没有发现在因子负荷或截距方面存在与受试者相关的显著差异。两个被试的数据因子结构基本相同。潜因子均值的比较结果显示,受试者之间没有均值差异。我们讨论了 MAIN-TEACH 模型和与学科相关的一般教学差异研究的意义。

Research into mathematics education at university level includes a wide range of theoretical approaches. This poses considerable challenges to researchers in terms of understanding and harmonizing the compatibility and commensurability of those approaches. The research community has already problematised and studied these challenges using networking theories. The networking theories framework is taken as a starting point in this study to contrast different approaches and to broaden the comparison of different frameworks. In particular, three case studies framed in the Action, Process, Object, Schema Theory, in the Problem-Solving approach, and in the Anthropological Theory of the Didactic are analysed. The differences and possible similarities between the three with regard to the research questions addressed, their objects of study, their empirical bases, as well as their research ends are considered. The analysis offers an insight into the potential for collaboration and the networking of theories in the field of university mathematics education.

The selection of tasks based on the evaluation of task features can be considered a core practice of teaching and a relevant component of teaching quality. This is typically part of teachers’ preparation for their classroom teaching, which prompts the following question: What are the characteristics of the tasks that teachers use when selecting tasks for differentiated teaching? To answer this question, we analyzed systematic differences in the focus of 78 in-service high school and lower secondary school teachers during the evaluation of task features. The teachers had to select eight tasks about the practice of fractions with respect to their differentiation potential—operationalizing their adaptive teaching competence from a mathematics educational perspective. To analyze the differences, we performed a cluster analysis of the task features that the teachers drew upon. Three groups of teachers could be identified with variations in their focus on directly or indirectly relevant, domain-specific or domain-general task features. Taking into account such variations may explain differences in teaching quality and student outcomes and may be relevant when designing teacher professional development programs.

根据任务特征的评价来选择任务,可以说是教学的核心实践,也是教学质量的相关组成部分。这通常是教师课堂教学准备工作的一部分,由此引发了以下问题:教师在选择差异化教学任务时所使用的任务有哪些特点?为了回答这个问题,我们分析了 78 名在职高中和初中教师在评价任务特征时关注点的系统性差异。这些教师必须从数学教育的角度出发,根据其差异化潜力选择八项有关分数练习的任务--操作其适应性教学能力。为了分析差异,我们对教师所采用的任务特征进行了聚类分析。我们发现,三组教师在关注直接或间接相关、特定领域或一般领域的任务特征方面存在差异。考虑到这些差异,就可以解释教学质量和学生成绩的差异,并在设计教师专业发展计划时有所借鉴。

In this paper, we present a qualitative study on what values students perceive in their abstract algebra course. We interviewed six undergraduates early in their abstract algebra course and then again after their course was completed about what motivated them to learn abstract algebra and what value they saw in the subject. The key finding from the analysis was that participants found intrinsic value (i.e., their enjoyment of the subject) to be essential to learning abstract algebra. While participants desired utility value in the form of mathematical applications, they ultimately did not find this necessary to learn abstract algebra. Finally, some participants had different motivations for learning abstract algebra than for learning other branches of advanced mathematics, such as real analysis, suggesting that motivation research in mathematics education should not treat mathematics as a unitary construct. We offer analysis about how the nature of advanced theoretical proof-oriented mathematics may have contributed to these findings.

在本文中,我们介绍了一项关于学生在抽象代数课程中感知到的价值的定性研究。我们在六名本科生学习抽象代数课程的初期对他们进行了访谈,并在课程结束后再次访谈了他们学习抽象代数的动机以及他们在这门课程中看到的价值。分析的主要发现是,学员认为内在价值(即他们对该科目的喜爱)对学习抽象代数至关重要。虽然学员们希望获得数学应用形式的实用价值,但他们最终并不认为这是学习抽象代数的必要条件。最后,一些参与者学习抽象代数的动机与学习其他高等数学分支(如实分析)的动机不同,这表明数学教育中的动机研究不应将数学作为一个单一的建构。我们分析了以证明为导向的高等数学理论的性质是如何促成这些发现的。

While proof has been studied from different perspectives in the mathematics education literature for decades, students continue to struggle to build proof comprehension. Complicating this, the manner in which proof comprehension is assessed largely remains to be the definition-theorem-proof format in which students are asked to reproduce proofs or similar proofs that are presented in class. This approach can encourage students to memorize proofs rather than develop tools for syllogistic reasoning. This paper reports on a seven-year collaboration among research mathematicians and mathematics educators. Following a model for proof comprehension, they implemented a cycle of planning assessments, implementing them and evaluating student responses in several courses each semester for three years at two universities. The model-based assessments were designed with probing questions about proofs or subproofs to point student attention to the relationships among definitions, statements and their relationships, as well as the logic used to help students to both develop proof knowledge and demonstrate their mathematical thinking. Discrepancies between the intention of assessments and student responses led to refinements as the team reviewed the results to inform its practice. Collaboration, experience and empirical data informed the development of the new Promoting Reasoning in Undergraduate Mathematics (PRIUM) Qualitative Framework for Proof Comprehension. The paper discusses three main results: the Framework and how to use it, the Framework’s utility at the individual, course and program levels of departmental evaluation, and a collaborative research process that may be utilized between research mathematics educators and mathematicians.

几十年来,数学教育文献从不同角度对证明进行了研究,但学生在建立证明理解能力方面仍然步履维艰。更复杂的是,评估证明理解能力的方式在很大程度上仍然是定义-定理-证明的形式,即要求学生重现证明或课堂上展示的类似证明。这种方法可能会鼓励学生死记硬背证明,而不是开发进行合情推理的工具。本文报告了研究数学家和数学教育工作者之间长达七年的合作。按照证明理解的模式,他们在两所大学实施了一个周期的评估计划、实施评估和评估学生的反应,每学期在几门课程中进行,为期三年。基于模型的评估设计了有关证明或子证明的探究性问题,将学生的注意力引向定义、语句之间的关系及其使用的逻辑,以帮助学生发展证明知识并展示他们的数学思维。评估的意图与学生的回答之间存在差异,因此,评估小组在审查评估结果时对其进行了改进,以便为其实践提供参考。合作、经验和实证数据为开发新的 "促进本科数学推理(PRIUM)证明理解定性框架 "提供了依据。本文讨论了三个主要成果:该框架及其使用方法,该框架在个人、课程和项目层面的部门评估中的实用性,以及研究数学教育工作者和数学家之间可以利用的合作研究过程。

Affective and cognitive processes may be jointly researched to better understand mathematics learning, paying special interest to emotions related to knowledge acquisition. However, it remains necessary to explore these processes in studies linked to the education of pre-service mathematics teachers. This study aims to characterize epistemic emotions in different practices linked to the practice of mathematics teaching: problem-solving, anticipating what would happen with the students and reflecting on classroom implementation. It considers the theory of Mathematical Working Spaces to describe the mathematical and cognitive dimensions generated by epistemic emotions, paying special attention to the cognition-affect interaction and the workspace created. The results indicate that the epistemic emotions of the pre-service mathematics teachers associated with the distinct practices were different. Differences are observed in the interaction between emotions and cognitive epistemic actions, depending on whether the pre-service mathematics teachers analyze them within the framework of their own solving or anticipate them in their students. This reveals how personal work relates to what is considered to be suitable for students. Specifically, certain antecedents and consequences have been specified for the emotions of surprise and boredom in relation to the characteristics of the optimization problems and the cognitive activity of the subject when solving them. These results highlight the need to enhance the education of pre-service mathematics teachers through training that helps regulate their epistemic emotions and model effective strategies for regulating their own emotions and those of their students.

为了更好地理解数学学习,可以对情感和认知过程进行联合研究,特别关注与获取知 识有关的情感。然而,仍有必要在与职前数学教师教育相关的研究中探讨这些过程。本研究旨在描述与数学教学实践相关的不同实践中的认识情感特征:解决问题、预测学生会发生什么以及反思课堂实施情况。研究采用 "数学工作空间 "理论来描述认识情绪所产生的数学和认知维度,特别关注认知与影响之间的相互作用以及所创建的工作空间。研究结果表明,职前数学教师的认识情绪与不同的教学实践是不同的。根据职前数学教师是在自己的解题框架内分析情感,还是在学生身上预测情感,可以观察到情感与认知认识行动之间的相互作用存在差异。这揭示了个人工作与被认为适合学生的工作之间的关系。具体地说,惊讶和厌烦情绪的某些前因后果与优化问题的特点和主体在解决这些问题时的认知活动有关。这些结果突出表明,有必要通过培训加强对职前数学教师的教育,以帮助他们调节认识情绪,并为他们提供调节自己和学生情绪的有效策略。

This research, following a sequential mixed-methods design, delves into metacognitive control in problem solving among 5- to 6-year-olds, using two floor-robot environments. In an initial qualitative phase, 82 pupils participated in tasks in which they directed a floor robot to one of two targets, with the closer target requiring more cognitive effort due to the turns involved. The results of this phase revealed that younger students often rationalised their decisions based on reasons unrelated to the difficulty of the task, highlighting limitations in children’s language and abstract thinking skills and leading to the need for a second quantitative study. In this subsequent stage, involving 117 students, a computerised floor-robot simulator was used. The simulator executed the students’ planned movements and provided feedback on their validity. Each participant had three attempts per problem, with the option to change their target each time. The simulator stored the information pertaining to the chosen resolution path, design of the plan, and re-evaluation of decision making based on the results and feedback received. This study aims to describe the criteria upon which students base their metacognitive control processes in decision making within problem-solving programming tasks. Additionally, through a comparative analysis focusing on age and gender, this research aims to assess the relationship between metacognitive processes and success in problem-solving programming tasks.

本研究采用顺序混合方法设计,利用两个落地机器人环境,深入研究 5-6 岁儿童在解决问题过程中的元认知控制。在最初的定性阶段,82 名小学生参与了引导落地机器人到达两个目标之一的任务,其中距离较近的目标因涉及转弯而需要更多的认知努力。这一阶段的结果表明,年龄较小的学生往往会根据与任务难度无关的理由做出合理的决定,这凸显了儿童语言和抽象思维能力的局限性,因此有必要进行第二次定量研究。在随后的阶段中,有 117 名学生参与,使用了计算机化的地板机器人模拟器。模拟器执行学生计划好的动作,并就动作的有效性提供反馈。每个学员对每个问题都有三次尝试机会,每次都可以改变目标。模拟器存储了与所选解决路径、计划设计以及根据结果和反馈重新评估决策有关的信息。本研究旨在描述学生在解决问题的编程任务中进行决策时所依据的元认知控制过程的标准。此外,通过以年龄和性别为重点的比较分析,本研究旨在评估元认知过程与在解决问题的编程任务中取得成功之间的关系。

Identifying mathematically gifted students is an important objective in mathematics education. To describe skills typical of these students, researchers pose problems in several mathematical domains whose solutions require using different mathematical capacities, such as visualization, generalization, proof, creativity, etc. This paper presents an analysis of the solutions to two problems by 75 students (aged 11–14), as part of the selection test for a workshop to stimulate mathematical talent. These problems require the use of the capacity for mathematical generalization of solution methods. We define a set of descriptors of such capacity, use them to analyze students’ solutions, and evaluate how well students with high capacity for generalization can be distinguished from average students. The results indicate that the two problems are suitable for identifying potential mathematically gifted students and several descriptors have high discriminatory power to identify students with high or low capacity for generalization.

识别数学资优生是数学教育的一个重要目标。为了描述这些学生的典型技能,研究人员提出了一些数学领域的问题,这些问题的解决需要使用不同的数学能力,如可视化、概括、证明、创造力等。本文分析了 75 名学生(11-14 岁)对两个问题的解决方法,这两个问题是激发数学人才研 讨会选拔测试的一部分。这些问题需要利用数学概括解题方法的能力。我们为这种能力定义了一套描述指标,用它们来分析学生的解题方法,并评估如何将概括能力强的学生与普通学生区分开来。结果表明,这两个问题适合用于识别潜在的数学资优生,而几个描述指标对识别概括能力高或低的学生具有很强的鉴别力。

The development of professional digital competencies is an important condition for a meaningful integration of digital technologies in mathematics education. A widely used and empirically studied approach for the professional development of in-service teachers are teacher design teams, in which lessons are collaboratively planned, implemented and reflected. However, this approach has not yet been considered for the collaboration of pre-service and in-service teachers. Therefore, this article examines in a holistic case study mixed teacher design teams composed of pre-service and in-service teachers. A total of 23 interviews were conducted with pre-service and in-service teachers and analyzed by inductive development of categories using the method of qualitative content analysis. The case study shows among other things, that the different prerequisites of the participants can lead to a relatively clear division of roles within the collaboration, which turns out to be suitable for the professionalization of both pre-service and in-service mathematics teachers.

培养专业数字能力是将数字技术有意义地融入数学教育的重要条件。教师设计团队是在职教师专业发展中一种广泛使用并经过实证研究的方法,在这一团队中,教师们共同规划、实施和反思课程。然而,这种方法尚未被考虑用于职前和在职教师的合作。因此,本文通过一项整体案例研究,探讨了由职前和在职教师组成的混合教师设计团队。对职前和在职教师共进行了 23 次访谈,并采用定性内容分析法对访谈内容进行了归纳分类分析。案例研究表明,参与者的不同先决条件可以导致合作中相对明确的角色分工,从而适合职前和在职数学教师的专业化发展。

This study contributes to Action, Process, Object, Schema (APOS) theory research by showing two approaches used by advanced mathematics students to construct relations between higher-order derivatives to solve complex problems. We show evidence of students’ ability to perform Actions on their graphing derivative Schema, that is, of its thematization. It also contributes to the literature on the learning of differential calculus by showing how advanced students use their knowledge to construct relations between concepts when facing complex situations. The work of three graduate students on transforming complex graphs and determining their properties and their relation to the domain structure is analyzed to determine their solution approaches. Their graphing derivative Schema is analyzed in depth in terms of the construction of relations among the Schema structures and assimilation and accommodation mechanisms involved in thematization in APOS theory. These findings are important in informing and developing didactic strategies to foster university students’ understanding of derivatives, which can smoothe the transition to the study of advanced mathematics courses.

本研究通过展示高等数学学生用来构建高阶导数之间关系以解决复杂问题的两种方法,为行动、过程、对象、模式(APOS)理论研究做出了贡献。我们展示了学生对其图解导数模式(即其主题化)进行操作的能力。通过展示高年级学生在面对复杂情况时如何利用所学知识构建概念之间的关系,这也为微积分学习方面的文献做出了贡献。本研究分析了三位研究生在转换复杂图形、确定其属性及其与领域结构的关系方面所做的工作,以确定他们的求解方法。我们还深入分析了他们绘制衍生模式图的过程,包括模式结构之间关系的构建,以及 APOS 理论中主题化过程中涉及的同化和调适机制。这些研究结果对于指导和制定教学策略,培养大学生对导数的理解,从而顺利过渡到高等数学课程的学习具有重要意义。
