Measuring Income Inequality in a General Education or Calculus Mathematics Classroom

Abstract

Income inequality is a central social justice concern, and hence excellent motivation for real-world applications in mathematics classrooms at every level. We describe the Mathematics for Social Justice course at Saint Michael’s College, giving a specific example of one of the typical social justice projects for the course, and showing how projects can be adapted to other courses such as Calculus. The projects described focus on the Gini coefficient, a commonly used measure of income inequality. The original lesson used the trapezoid rule and Microsoft Excel to estimate the Gini coefficient for a country, while the project developed for a Calculus I course uses Maple to fit a power function to data and then integration to calculate the Gini coefficient. We also include readings on the Gini coefficient’s role in policy formulation and advocacy.     

A preliminary study of multiple college admission criteria in Taiwan: the relationship among motivation,standardized tests,high school achievements,and college success

ABSTRACT

A new college admission policy will be implemented in Taiwan in 2022. The purpose of this study was to understand the relationship between admission criteria and college success. Data was obtained from the Taiwan Higher Education Database; a sample size of 8443 students from 156 universities was used in this study. By using the structural equation model, this study tested a research model that included factors such as motivation, standardized test scores, high school achievements, and college success. The findings revealed that the General Scholastic Ability Test scores (in Chinese, English, Social Studies) and high school average academic grades are significantly associated with college success. A student’s motivation to complete a certain major can significantly predict the quality of student effort and influence college success. These findings highlight the importance of some admission criteria and provide practical implications for educational policy-makers, school administrators, students, and parents.     

Leading Undergraduate Research Projects in Mathematical Modeling

Abstract

In this article, we provide some useful perspectives and experiences in mentoring students in undergraduate research (UR) in mathematical modeling using differential equations. To engage students in this topic, we present a systematic approach to the creation of rich problems from real-world phenomena; present mathematical models that are derived from calculus, but can be suitably modified to solve more complex problems; and finally provide pointers on how to train students through the UR process that can help to impact student’s future academic and non-academic careers.     

What Counts and How: Mathematics Teaching in Culturally, Linguistically, and Socioeconomically Diverse Urban Settings

This article presents findings from an ongoing study of urban teachers' efforts to embrace mathematics reform with student populations that are culturally, linguistically, and socioeconomically diverse (CLSD). We investigate the teacher's role in providing accessible and valuable mathematical learning opportunities to diverse students. Through narrative vignettes of practice and analyses of the personal and intellectual resources teachers draw on in CLSD contexts, we examine the challenges and possibilities two third-grade teachers face as they attempt such reform. One teacher's strengths were in making cultural connections with her students; the other's strengths were in pursuing complex and meaningful mathematics with her students. Building on our analysis, we offer a framework for examining the work of attending to mathematical and cultural issues simultaneously. Our findings suggest that such work is complex; however, teachers are seldom supported in their efforts to integrate these two perspectives. Our aim is to examine the dimensions of culturally relevant mathematics teaching and explore where the fields of mathematics and bilingual-bicultural education need to speak to one another.     

"聋哑英语"的成因及对策

在我国"聋哑英语"的现象普遍存在.造成此现象的原因是语言环境,学习动机,语言输入和情感因素.而在多媒体发达的今天,"视听说"教学正好为学习者创造了一个良好的外语学习环境和提供大量有意义的语言输入.学习者在视听后能进行一系列"说"的活动.在进行"视听说"的教学过程中,教师还需要调动学习者的各种情感因素,使到学习者敢于开口,乐于开口说英语.     

英语教学中实施教唱英文歌曲的实验研究

激励机制在民族社区管理中的运用

社区是社会结构的中观层次,作为纽带和桥梁,将宏现社会与微观的个体紧密联系在一起。少数民族地区的社会发展应当建立在社区发展之上,社区的发展则依赖于外源和内源两种动力的整合,目前我国民族社区的发展更多表现为外力推动型,社区内源动力激发明显不足,而内源动力的激发,科学的社区管理是决定性因素。现代社区管理更加注重用人的价值观来阐释各种管理,以适应多变的环境因素,主张以激励方式为主,促发人的创造潜力,已从传统简单的人机效率满足转向社会效益和社区效力的取得以及对人价值的尊重、人的需要的满足和人潜力的发挥。因而,激励机制已成为当代社区管理中最重要的方法之一。在民族社区的管理中,综合借鉴相关学科的成熟理论,讨论有效的激励的形成,对于激发民族社区内源动力,体现以人为本,实现民族社区的全面、协调和可持续发展有着重要的理论和实践意义。
