Mathematical Identity and the Role of the Educator 数学同一性与教育者的角色
Pub Date : 2022-05-25 DOI: 10.52214/jmetc.v13i1.9187
K. Barba
Mathematical identity is a socio-motivational construct known to be a predictor of mathematical achievement. Students who identify positively with mathematics are more likely to pursue advanced courses and Science, Technology, Engineering, and Mathematics (STEM)-related occupations. Although mathematical identity is shaped by a myriad of internal and external factors on both a small and large scale, educators play a significant role in the formation of their students’ mathematical identities. This paper presents an overview of research regarding those pedagogical practices for teaching mathematics that can foster the formation of positive mathematical identities.
数学身份是一种社会动机结构,被认为是数学成就的预测因子。积极认同数学的学生更有可能攻读高级课程以及科学、技术、工程和数学(STEM)相关职业。尽管数学身份是由无数内部和外部因素在小范围和大范围内形成的,但教育工作者在学生数学身份的形成中发挥着重要作用。本文概述了有关数学教学实践的研究,这些教学实践可以促进积极数学身份的形成。

This study reports on efforts over several years to design and implement a yearlong intervention intended to support secondary mathematics teachers in their early years of teaching. The intervention is designed to retain early career mathematics teachers in the professions by engaging them in the development of meaningful professional relationships with a school-based mentors, and  by creating an online community of practice for support with other professionals. The intervention itself consists of early career teachers and their mentors participating in monthly professional learning activities such as online meetings, videoconferencing panels with experts, and collaborative reading and discussing timely, purposeful, and relevant content. The intervention is designed to not over burden the participants and to be feasible for national implementation with little to no funding. This article presents the purpose, design, and implementations of the intervention, as well as a discussion of challenges faced and potential next steps and future directions for similar work. 
这项研究报告了几年来为设计和实施一项为期一年的干预措施所做的努力,该干预措施旨在支持中学数学教师的早期教学。该干预措施旨在通过让早期职业数学教师与学校导师建立有意义的职业关系,以及创建一个在线实践社区以获得其他专业人员的支持,来留住他们。干预措施本身包括早期职业教师及其导师每月参加专业学习活动,如在线会议、与专家的视频会议小组讨论,以及合作阅读和讨论及时、有目的和相关的内容。干预措施的目的是不让参与者负担过重,并且在几乎没有资金的情况下,对于国家实施是可行的。本文介绍了干预的目的、设计和实现,并讨论了面临的挑战、潜在的下一步行动和类似工作的未来方向。

Teaching Statistics with an Inquiry-Based Learning Approach 研究性学习方法下的统计学教学
Pub Date : 2022-02-05 DOI: 10.52214/jmetc.v12i2.8544
J. Lee, S. Ban
Two case studies were conducted to examine whether inquiry-based learning (IBL) can help students in understanding normal distributions, and to determine if IBL methods have any effect on students' conceptual and computational capabilities. There were 16 students in the traditional class and 17 students in the IBL-implemented class who participated in each of two case studies. The experimental group performed significantly better than the control group in terms of conceptual understanding and computational skills. These outcomes suggest that IBL methods such as discussions, asking questions, and guided lectures helped students to develop statistical reasoning.  
进行了两个案例研究,以检验基于探究的学习(IBL)是否可以帮助学生理解正态分布,并确定IBL方法是否对学生的概念和计算能力有任何影响。传统班有16名学生,IBL实施班有17名学生,他们分别参与了两个案例研究。实验组在概念理解和计算技能方面明显优于对照组。这些结果表明,IBL方法,如讨论、提问和指导讲座,有助于学生发展统计推理。

Metacognitive Skills of Students in a Mathematics Class with Supplemental Instruction and Online Homework 辅以在线作业的数学课堂学生的元认知技能
Pub Date : 2020-07-15 DOI: 10.7916/JMETC.V11I1.6707
Bibi Rabia Khan
Improving students’ performance in Calculus is a challenge for many colleges and universities. One way of improving students' performance as well as their metacognition and study skills is to provide opportunities for them to receive support outside of the lecture. A modified version of the Motivated Strategies for Learning Questionnaire (MSLQ) was used to reveal any significant differences in metacognition and study strategies between students in a class with supplemental instruction with peer tutors and a dynamic online homework software (WebAssign), and students in a traditional class without these additional supports. Surveys and interviews were utilized to provide anecdotal evidence on the influence of WebAssign and supplemental instruction sessions on study skills and metacognition and whether students preferred WebAssign to traditional homework. Overall, the study showed no significant difference between the two groups in seven out of eight sub-scales of metacognitive skills and study strategies. Students reported that the supplemental instruction sessions and the WebAssign software were beneficial to their success.
提高学生的微积分成绩是许多高校面临的挑战。提高学生表现以及他们的元认知和学习技能的一种方法是为他们提供在课堂之外获得支持的机会。使用改进版的动机学习策略问卷(MSLQ)来揭示在有同伴导师和动态在线作业软件(WebAssign)的课堂上进行补充指导的学生与在没有这些额外支持的传统课堂上学习的学生之间在元认知和学习策略上的显着差异。调查和访谈被用来提供关于网络作业和补充教学课程对学习技能和元认知的影响的轶事证据,以及学生是否更喜欢网络作业而不是传统作业。总体而言,研究显示两组在元认知技能和学习策略的8个子量表中有7个没有显著差异。学生们报告说,补充教学课程和WebAssign软件对他们的成功有帮助。

Inverted Tasks and Bracketed Tasks in Mathematical Problem Posing. 数学问题提出中的倒置任务和括号任务。

Benjamin Dickman
We present in this paper a pair of approaches to support mathematics educators and learners in formulating original tasks. In particular, we facilitate the posing of rich mathematical problems by using two novel methods that were created by a mathematics department at a K-12 school in the United States, and further developed alongside our students as well as a wider professional learning team of master teachers. We situate our work within the broader literature on mathematical problem posing and describe our strategies by including examples of their use in generating problems and by providing examples of authentic student-assigned tasks that were created with our approaches.
在本文中,我们提出了两种方法来支持数学教育者和学习者制定原始任务。特别是,我们通过使用两种新颖的方法来帮助提出丰富的数学问题,这两种方法是由美国一所K-12学校的数学系创建的,并与我们的学生以及更广泛的专业学习团队一起进一步发展。我们将我们的工作置于关于数学问题提出的更广泛的文献中,并通过包括它们在生成问题中的使用示例以及通过提供使用我们的方法创建的真实的学生分配任务的示例来描述我们的策略。
