Math for the Benefit of Society: A New MATLAB-Based Gen-Ed Course

Abstract

Responding to a call for national reform of mathematical education, as well as a college-wide revision of general education (GE) requirements, we describe a new entry-level, GE course focused on the humanitarian utility of mathematics. This includes a detailed overview of how we taught the course using a Humanitarian MATLAB Lab Manual developed collaboratively with undergraduate students within an applied math program. A PRIMUS edition of this manual with complete MATLAB materials for a GE course is included as an Appendix for interested readers. A variety of social justice issues including peace-building after modern civil wars, continued cancer risk after Chernobyl, gang reduction, various dimensions of human trafficking, the use of a tractor and herbicide in subsistence farming, equitable resource distribution during the Syrian refugee crisis, and access to HIV vaccines are included in this special edition of the manual.     

文献标引是需要智慧的近乎艺术创造的处理过程

标引人员的智慧与文献标引的质量密切相关。提高标引人员的素养很重要。标引人员需要在标引实践中磨练。自动标引研究已有半个世纪，其标引质量至今未能超过人工标引而取代人工标引，究其原因在于计算机不具备优秀标引人员的智慧，不适应近乎艺术创造的标引作业。可以揣测，没有标引人员介入的、高度自动化的文献标引处理的实现，至少还要等待一个相当长的时间。人工标引研究的成果将有助于自动标引研究中一些难题的解决。不可轻视人工标引的研究。     

Increasing inclusion in early childhood: Key Word Sign as a communication partner intervention

The importance of communication partner intervention to support the successful implementation of augmentative and alternative communication (AAC) strategies has been established. Despite this, limited knowledge and use of AAC form serious barriers to inclusion. In this study, 196 pre-service early childhood teachers were taught key word signing (KWS), one common form of AAC, along with approximately 80 Auslan signs. Participants were asked to develop ideas for implementing KWS in early childhood settings. Using participant journal entries, we conducted a thematic analysis to investigate the perceived impact of using KWS in early childhood practice. Participants reported the belief that KWS was beneficial for supporting communication development. Participants identified that using KWS can facilitate inclusive approaches through reducing barriers to participation, valuing diversity, and supporting a sense of belonging. Additionally, participants reported that engaging with inclusive approaches to using KWS formed a catalyst for fostering openness to inclusion more broadly. Overall, the findings demonstrate that approaching KWS as a communication partner intervention holds potential for contributing to the conditions for inclusion in early childhood settings in line with social relational and human rights models of disability. Implications for teacher education and inclusive practice are discussed, as are the limitations of this study.
