Teacher productive disposition is considered as one of the key strands of mathematical proficiency. Teacher disposition and positioning (disposition in action) toward mathematics influence student learning. However, teachers’ productive disposition does not always translate into productive positioning in the mathematics classroom, and vice versa. In this study, we selected teacher dis/position as the unit of analysis to explore the phenomenon of two middle school mathematics teachers’ self-reported affective disposition and observed positioning-by-others. Grounded in positioning theory the relationship between teacher disposition and positioning-by-others was examined utilizing a cross-case analysis. Results of the study indicate that dispositional characteristics such as attitude, self-concept, and nature of mathematics were significantly different between the cases. The study findings also suggest that interconnectedness between teacher core disposition and positional situatedness could potentially contribute to understanding and addressing the complexity of teaching and learning in the mathematics classroom.
教师的生产倾向被认为是数学熟练程度的关键因素之一。教师对数学的倾向和定位(行动倾向)影响学生的学习。然而,在数学课堂中,教师的生产倾向并不一定转化为生产定位,反之亦然。本研究以教师错位为分析单元,探讨了两名中学数学教师自我报告的情感倾向和观察到的他人定位的现象。本研究以定位理论为基础,以跨个案分析的方法检视教师性格倾向与他人定位之间的关系。研究结果表明,学生的性格特征如态度、自我概念和数学性质在不同的情况下存在显著差异。研究结果还表明,教师核心倾向和位置情境之间的相互联系可能有助于理解和解决数学课堂教与学的复杂性。

The effect of interaction patterns on JS3 learners’ retention in geometric construction was investigated in Anambra State, Nigeria. The researchers used a quasi-experimental approach with a non-equivalent control group for the pre- and post-test. The population consisted of 1,813 JS3 leaners. The study’s subjects were a group of 155 JS3 learners drawn from two schools. Two JS3 classes in the schools were assigned to the experimental and control groups at random. The geometric construction retention test (GCRT) was used to collect data, and it was validated by three experts. The reliability coefficient of the GCRT was 0.80. The mean and standard deviation of the data were used to report the study’s questions, whereas the hypotheses were tested via analysis of covariance at a 0.05 level of significance. According to the findings, students taught geometric construction utilizing interaction patterns remembered more material than those taught using the expository approach. It also found a statistically significant difference in retention between urban and rural learners, favoring urban learners. The interaction effect of group and location on student retention was not significant. One recommendation of this study is that teachers should use interaction patterns as an instructional method when teaching geometric construction.
在尼日利亚的阿南布拉州,研究了互动模式对JS3学习者几何结构记忆的影响。研究人员采用了准实验的方法,在前后测试中使用了一个非等效的对照组。总体由1,813个JS3学习者组成。研究对象是来自两所学校的155名JS3学习者。将学校的两个JS3班随机分为实验组和对照组。采用几何结构保留测验(GCRT)收集数据,并由三位专家进行验证。GCRT的信度系数为0.80。数据的均值和标准差用于报告研究的问题,而假设通过协方差分析在0.05显著性水平上进行检验。根据研究结果,使用互动模式学习几何结构的学生比使用说明性方法的学生记住了更多的材料。该研究还发现,城市和农村学习者在保留率方面存在统计学上的显著差异,有利于城市学习者。群体和地域对学生滞留的交互作用不显著。本研究的一个建议是,教师在教学几何结构时应使用互动模式作为教学方法。

Turkey experiences distance education at the master’s and doctorate degrees for the first time. This study aims to reveal the essence of the distance education experiences of mathematics teachers who continue their postgraduate education with distance education due to the COVID-19 pandemic. This study was carried out using the phenomenological research design with six mathematics teachers who continue their postgraduate education at a state university in the Central Anatolia Region in the 2019-2020 academic year. Of the participants selected by the criterion sampling, three were master’s degree students and three were doctoral degree students. Research data were collected using semi-structured interview forms designed in line with expert opinions. The interviews were conducted online via video call on the WhatsApp application due to the COVID-19 pandemic. The experiences of the participants were identified with the phenomenon of “solo pantomime”. Participants had positive experiences such as easy access, possibility of review, improvement in technological pedagogical content knowledge, and negative experiences such as communication and connection problems, the irregularity in the schedule, inadequacy of the lesson hours, and focusing problems regarding synchronized distance education. Distance graduate education is also considered quite suitable for mathematics education courses, but insufficient for mathematics field courses. It is also understood that some participants had plans to make radical changes in their thesis topics. Participants avoid long-term experimental studies or studies that can be conducted with a large sample, and they tend towards studies that can be carried out with document analysis or small groups and had problems with their supervisors.
土耳其首次在硕士和博士学位上实施远程教育。本研究旨在揭示新型冠状病毒肺炎疫情背景下继续远程教育研究生数学教师远程教育经历的本质。本研究采用现象学研究设计,对6名2019-2020学年在安纳托利亚中部地区一所国立大学继续研究生教育的数学教师进行了研究。标准抽样选取的参与者中,硕士生3人,博士生3人。研究数据收集采用半结构化的访谈形式设计符合专家意见。由于新冠肺炎大流行,采访是通过WhatsApp应用程序在线视频通话进行的。参与者的经历与“独奏哑剧”现象一致。参与者的积极体验是:获取方便、复习的可能性、技术教学内容知识的提高;消极体验是:同步远程教育的沟通和连接问题、时间表不规律、课时不足、集中问题。远程研究生教育也被认为非常适合数学教育类课程,但不适合数学领域类课程。据了解,一些参与者还计划对论文主题进行重大修改。参与者避免长期的实验研究或可以用大样本进行的研究,他们倾向于可以用文件分析或小组进行的研究,并且与他们的主管有问题。

Three mathematics teacher educators who were assigned to teach fundamental concepts of algebra course in a teacher education college, as well as their prospective elementary mathematics teachers who took the course, took part in a job-embedded, context-specific, and content-based comprehensive professional development (PD) program on assessment for learning (AfL). Three teacher educators and 129 prospective elementary mathematics teachers from three teacher education colleges took part in the study. The findings demonstrated that prospective elementary mathematics teachers in the intervention group significantly outperformed prospective teachers in both of the comparative groups in their post-test scores in algebra. Furthermore, it was found out that after the intervention, there was no statistically significant mean difference among achiever levels in the treatment group on post-test scores, despite a statistically significant mean difference among achiever levels in their pre-test scores. This research adds to our knowledge of the impact of comprehensive, job-embedded, context-specific, and content-based PD on prospective teachers’ achievements in algebra in elementary school mathematics teacher education. Implications of implementing AfL as well as recommendations for further research are highlighted.
三名在师范学院教授代数基本概念课程的数学教育教师,以及他们的准小学数学教师,参加了一项基于工作嵌入、情境特定、基于内容的学习评估综合专业发展(PD)计划。来自三所师范院校的三名教师教育工作者和129名小学数学准教师参与了研究。研究结果显示,干预组的小学数学准教师在代数测验后得分显著优于两组的准教师。此外,我们发现干预后,实验组各成就者水平在测试后得分上的平均差异无统计学意义,尽管各成就者水平在测试前得分上的平均差异有统计学意义。本研究增加了我们对小学数学教师教育中全面的、工作嵌入的、情境特定的和基于内容的PD对准教师代数成绩的影响的认识。强调了实施AfL的意义以及对进一步研究的建议。

The atom-bond sum-connectivity ( ABS ) index is a recently introduced variant of three earlier much studied graph-based molecular descriptors: connectivity (Randi´c), atom-bond connectivity, and sum-connectivity indices. In this paper, the graphs with minimum, second-minimum, maximum, and second-maximum values of the ABS index are determined over the class of connected unicyclic graphs with a fixed order. Possible chemical applications of the ABS index are also investigated on particular sets of chemical graphs

In this paper, we have tried to clearly explain the meaning of fractions and operations with fractions. Also, we have tried to illustrate with some examples how to apply the rules of operations with fractional numbers, giving different practical techniques through different figures, visualization methods, and concretizing problems. The paper presents with examples of the most common mistakes made by students, giving suggestions for their avoidance, as well as through a questionnaire, which considered the survey of 60 students of grade 6 of school, “Elena Gjika” City Prishtina, Kosovo, with the help of the statistical test we have concluded that practical techniques such as figures, visualizations, and video lessons have a close dependence on the meaning and operation of fractions.

Galois and Pataki Connections for Ordinary Functions and Super Relations 普通函数和超关系的伽罗瓦和帕塔基连接

A subset R of a product set X×Y is called a relation on X to Y . A relation U on the power set P (X) to Y is called a super relation on X to Y . The relation R can be identified, to some extent, with the set-valued function φR defined by φR (x) = R (x) = { y ∈ Y : (x, y) ∈ R } for all x ∈ X, and the union-preserving super relation R . defined by R (A) = R [A ] = ⋃ a∈A R (a) for all A ⊆ X. By using the relation R , we also define two super relations lbR and clR on Y to X such that lbR (B) = { x ∈ X : {x}×B ⊆ R } and clR (B) = { x ∈ X : R (x) ∩ B 6= ∅ } for all B ⊆ X . By using complement and inverse relations, we prove that lbR = cl c Rc and clR (B) = R−1 [B ] . We also consider the dual super relations ubR = lbR−1 and intR = cl c R ◦ CY . If U is a super relation on X to Y and V is a super relation on Y to X, then having in mind Galois connections and residuated mappings, we say that U is V –normal if, for all A ⊆ X and B ⊆ Y , we have U (A) ⊆ B if and only if A ⊆ V (B) . Thus, if U is V –normal, then by defining Φ = V ◦ U and following Pataki’s ideas, we see that U is Φ–regular in the sense that, for all A1 , A2 ⊆ X, we have U (A1) ⊆ U (A2) if and only if A1 ⊆ Φ (A2) . In this paper, by considering a relator (family of relations) R on X to Y , we investigate normality properties of the more general super relations lbR = ⋃ R∈R lbR and clR = ⋂ R∈R clR , and their duals ubR = lbR−1 and intR = cl c R ◦ CY . However, as some applicable results of the paper, we only prove that if R is a relation on X to Y , then the following assertions hold : (1) clR−1 is intR – normal, or equivalently clR is intR−1 – normal ; (2) ub c R is lbR ◦ CY – normal, or equivalently lb c R is ubR ◦ CX – normal ; (3) R is a function of X to Y if and only if clR−1 is clR – normal, or equivalently intR is intR−1 – normal . The closure-interior and the upper-lower-bound Galois connections, established in assertions (1) and (2), are applied in the calculus of relations and the completion of posets, respectively. Some of the implications in assertion (3) require that Y 6= ∅ .
乘积集X×Y的子集R称为X到Y的关系。幂集P (X)到Y上的关系U称为X到Y上的超关系。关系R在一定程度上可以用φR (x) = R (x) = {y∈y: (x, y)∈R}定义的集值函数φR和保并超关系R来标识。由R (A) = R [A] = ` ` A∈A R (A)定义,对于所有A的X,我们还利用关系R在Y到X上定义了两个超关系lbR和clR,使得对于所有B的X, lbR (B) = {X∈X: {X}×B任任R}, clR (B) = {X∈X: R (X)∩B 6=∅}。利用补和逆关系,证明了lbR = cl c Rc和clR (B) = R−1 [B]。我们还考虑了对偶超关系ubR = lbR−1和intR = cl c R◦CY。如果U是X到Y上的超关系,V是Y到X上的超关系,那么考虑到伽罗瓦连接和剩余映射,我们说U是V -正规的,当且仅当,对于所有的a, X和B,我们有U (a),它是B。因此,如果U为V -法线,则通过定义Φ = V◦U并遵循Pataki的思想,我们可以看到U为Φ-regular,即对于所有A1、A2的任一个X,当且仅当A1≥Φ (A2)时,我们有U (A1)≥U (A2)。本文通过考虑X到Y上的一个关系族R,研究了更一般的超关系lbR =∈R lbR和clR = R∈R clR及其对偶ubR = lbR−1和intR = cl c R◦CY的正态性性质。然而,作为本文的一些适用结果,我们只证明了如果R是X到Y上的关系,则下列断言成立:(1)clR−1是intR -正规的,或者等价地clR是intR−1 -正规的;(2) b c R为lbR◦CY -正常,或b c R为ubR◦CX -正常;(3) R是X到Y的函数当且仅当clR−1是clR -正规的,或者等价地,intR是intR−1 -正规的。在断言(1)和断言(2)中建立的闭包内连接和上界下界伽罗瓦连接分别应用于关系演算和偏序集补全。断言(3)中的某些含意要求y6 =∅。

The closure-interior and the upper-lower-bound Galois connections, established in assertions (1) and (2), are applied in the calculus of relations and the completion of posets, respectively. Some of the implications in assertion (3) require that Y 6= ∅ .","PeriodicalId":29770,"journal":{"name":"International Electronic Journal of Mathematics Education","volume":"29 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2022-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87061791","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
