Expeditionary Learning in Information Systems: Definition,Implementation, and Assessment

In the natural sciences, collecting, cataloguing, and comparing living specimens have long been a popular, collaborative mode of discovery and learning. New species are discovered, and the relationships between species are theorized. From Aristotle's “History of Animals” to Darwin's “On the Origin of Species”, and beyond, this process of learning through expedition has yielded bountiful knowledge and insights to students of science. In this paper, we propose that expeditionary learning can be applied to a softer science: the field of information systems. In the field of information systems, specimens (information systems) are created by humans, evolving with great speed. Expeditionary learning—where students collaboratively discover, catalog, and compare rapidly evolving information system specimens—is an innovative approach for learners in the IS field, and is effective in increasing IS program visibility and delivering significant, measurable community impact. Our results indicate that learning by expedition has a strong, positive community impact through educating external learners (such as high school and community college students, and the general public), and compares favorably to conventional experiential and service learning styles. Though expeditionary learning does not yield improved course evaluations, we demonstrate that learners’ perceived self‐knowledge and intentions to pursue the subject area are improved.

Classroom Questioning with Immediate Electronic Response: Do Clickers Improve Learning?

A number of studies have focused on how students and instructors feel about digital learning technologies. This research is focused on the substantive difference in learning outcomes between traditional classrooms and classrooms using clickers. A randomized block experimental design involving four sections of undergraduate Operations Management classes was used to determine if clicker systems increase student learning of both quantitative and conceptual material in Operations Management. Learning was measured using the difference between the scores on an entrance examination and the final examination. The findings of this research provide evidence that the use of immediate feedback using a technology like clickers can have a positive impact on student learning as measured by test scores.     

A study on the effects of education welfare action zone policy in Korea

This study was designed to analyze the effects of the support programs provided in education welfare action zones. Education welfare action zone policy came into effect by government from 2003 to guarantee actual educational opportunity to disadvantaged children in urban areas by providing educational, cultural, and welfare service. Education welfare action zones were selected in low-income group area in the metropolis. In this regard, both quantitative and qualitative analytical methods were used to ascertain the effects of the program. The qualitative analysis included a preliminary examination of conditions prior to the actual commencement of the program, which was then followed by an investigation of specific schools used, as case studies in order to identify the changes that had taken place during the program’s implementation process, and the program’s effect. Meanwhile, a quantitative analysis was employed to verify the actual changes that took place in several different aspects, changes that were revealed by the case studies.     

略论“两制”并存视野下中美对外政策的不同选择——《当代世界经济与政治》课程中美对外政策问题断想

面对二战后世界主题转换,世界格局变化,经济全球化发展不平衡不断加剧的形势,中国推进“两制”的关系的理论创新和发展,而美国从其国家利益和全球战略出发,在“两制”关系上,死抱冷战思维,并利用一切手段、一切可能钳制和牵制中国,无视多样性和差异性,继续以社会制度和意识形态划线,强制推行美国所谓的民主、价值观和实用标准。     

国内A股上市公司经营业绩的评价和改进建议——基于板块的DEA分析

数据包络分析(DEA)对于多投入与多产出的企业来讲是一种相对较为全面的业绩评价分析方法。文章采用上市公司能源板块的基本面数据,对能源板块诸公司的基本面和经营业绩进行了实证研究。通过DEA的技术效率和规模效益分析,从两方面得出结论:首先,为达到理想的经营业绩,非DEA有效的上市公司应按照技术效率和松驰变量的取值改变投入或产出量,根据规模效益指示的方向改进经营规模;其次,投资者应根据技术效率和各决策单元被参考次数理性地选择最优投资对象。     

基于应用型本科人才培养的离散数学教学改革探讨

《离散数学》作为信息管理与信息系统专业核心课程之一,由于概念多、理论性强且抽象,教学时容易造成知识点散、教师满堂灌的局面,使学生学习时感到吃力,从而失去对课程学习的兴趣。文章从信息管理与信息系统专业应用型人才培养的角度,对离散数学进行教学改革,广泛全面地增加应用案例,使学生在学习后能应用所学理论解决一定的实际问题。
