Lean six sigma is a management methodology that firms can employ to achieve substantial improvement in supply chain performance. However, few pedagogical exercises facilitate students’ use of a comprehensive set of lean six sigma principles within a supply chain context. We describe the Airplane Supply Chain Simulation that helps students understand how lean six sigma concepts may be leveraged to improve supply chain performance. The basis of this simulation is a four‐tier supply chain, consisting of suppliers (two tiers), a manufacturer, and a customer, that produces three models of paper airplanes to meet randomly distributed customer demand. In the first of three successive runs, a highly structured simulation is executed in which supply chain roles are well defined, material flows are convoluted, and a “push” production strategy is followed. The first simulation as the “current state” and, for the second and third simulation runs, challenge competing student teams to leverage lean six sigma concepts to develop a “future state” that enables the fulfillment of all customer orders at the lowest cost. Results based on statistical analyses of survey response data from 194 MBA students show that the Airplane Supply Chain Simulation is an effective participative, team‐based learning tool.  相似文献

Many potential employers expect that newly hired students will arrive on‐the‐job with the ability to analyze data, utilize spreadsheets, and communicate findings and recommendations. We designed the Ocean State Circuits, Inc. Forecasting Project to address these gaps in our students’ knowledge of analytical tools (such as the vlookup() function and pivot tables), their ability to write mathematical formulas in a spreadsheet, their understanding of more advanced data analysis features (e.g., regression, correlation), and their ability to communicate and present managerial conclusions. The exercise requires student teams to act as “consultants” and utilize spreadsheets to analyze and forecast the demand for a hypothetical set of products and then communicate their findings to “management” in a professionally formatted report document. A survey of students that have completed the exercise indicates that their knowledge level of the tools used in the project increased significantly from before to after they completed the case. Similarly, anecdotal feedback from employers suggests that students that have completed the exercise seem more capable of dissecting data when investigating business issues.  相似文献

Considerable research has compared how students learn science from computer simulations with how they learn from “traditional” classes. Little research has compared how students learn science from computer simulations with how they learn from direct experience in the real environment on which the simulations are based. This study compared two college classes studying introductory oceanography. One class learned using an interactive computer simulation based on a dynamic, three‐dimensional model of physical oceanography. The other class learned by spending a day on a research ship using scientific tools and instruments to measure physical properties of the ocean directly. In classes preceding and following the simulation or field experience, students performed the same exercises regarding currents and salinity, had the same instructor presentations, and did the same homework. The study found that the field experience helped contextualize learning for students with little prior experience of the ocean while the simulation made it easier for students to connect what they learned from it to other content they learned in class. These and other findings shed light on what computer simulations can and cannot help students learn, and what concepts are best learned in the real environment. © 2005 Wiley Periodicals, Inc.

Studies show that supply chain integration (SCI) is important to organizations. This article describes an activity that places students in the middle of an SCI scenario. The highly interactive hands‐on simulation requires only 50 to 60 minutes of classroom time, may be used with 18 to about 36 students, and involves minimal instructor preparation. Through the activity, students learn the basics of SCI and then analyze an SCI event to better appreciate the need for collaboration and information sharing. In courses that address supply chain management, instructors can use the activity early in the semester to introduce students to the complexities of supply chain networks. Alternatively, instructors may use the simulation later to provoke a more nuanced discussion.  相似文献

The aim of this study is to compare the role of the tutor in an online and a face‐to‐face problem‐based learning (PBL) session to shed light on potential differences of the tutor role in both settings. In this practice‐based study we compared the two groups with the same tutor undertaking the same module. Students completed questionnaires about tutor performance, student characteristics and the module. Marks on the end‐of‐module test were analysed. The tutor was interviewed about his expectations and experiences. One session of each group was recorded and analysed qualitatively. Results show tutor tasks appeared to be comparable in both settings with regard to “content and pedagogical content knowledge,” “group dynamics,” “process instruction” and “intermediary between faculty and students.” The face‐to‐face group rated tutor performance lower than the online students. Students and tutor identified the absence of nonverbal cues as a limitation of online PBL. In online sessions the tutor additionally provided technical support and moderated the chat box. It is recommended to involve an extra person in online sessions who is responsible for technical issues. This person could also check the chat box for messages of students. Future research should focus on the necessity of an extra tutor training for online sessions.  相似文献

The Software Engineering Apprentice   总被引：1，自引：1，他引：0  
The Software Engineering Apprentice is a model of programming instruction that focuses on “programming in the large.” We have developed a set of innovative laboratory programming exercises that can be used in a Fundamentals of Computer Science course sequence. The exercises revolve around a series of sophisticated “case studies”: complete software applications that we developed to exemplify good software engineering methods. In addition to functioning source code, the case studies include other software development artifacts: specifications, test plans, and design documents. As an alternative to the “build it from scratch then throw it away” mentality of most assignments in a first course, the Software Engineering Apprentice approach demands that students build upon large pre-existing software applications. Instead of the “language feature of the week” program assignments that are typical in these courses, the exercises we developed are modelled after tasks found in a real software development environment—testing, code comprehension, maintenance, modification, and enhancement.  相似文献

This article discusses some of the ethical dilemmas faced by writers who prepare marketing materials in engineering organizations; such writers include traditional technical writers whose documents are influenced by the marketing interests of the company and “boundary spanners” who write both technical and promotional materials. The article describes social, political, economic, and legal changes in the professions during the last 30 years and the growing influence of market‐driven decisions on ethical decision‐making. It briefly surveys the marketing literature that engineering marketers are reading. Finally, it suggests a question that marketing writers should ask themselves in examining rhetorical choices.  相似文献

New Zealander Sylvia Ashton‐Warner, a teacher in remote rural Māori schools in the 1940s–1950s, became internationally renowned as a novelist and educational theorist. Earlier commentators portrayed her educational theory as in conflict with those of her time and place, but recent studies conceptualise them as enabled by it. While space/place has often been considered the preserve of the geographer and time that of the historian, Henri Lefebvre and others suggest that: “these issues need to be thought together rather than separately” and that macro‐, meso‐ and micro‐levels of analysis be engaged simultaneously. The author traces how conceptual, linguistic, sensory and intellectual resources of the global “New Education” movement extended into the tiny bush‐encircled Māori communities in which Sylvia taught and wrote in the 1940s–1950s and surfaced in her writing. The article zooms in and out between the “the immensity of the global” (the New Education, the Second World War) and “the intimately tiny” (her classroom and home). The “data” include Sylvia’s non‐fiction education texts and official documents of her time: school curricula, education policy documents, Ministerial and Inspectors’ reports. What Lefebvre terms a “Rhythm analysis” of Ashton‐Warner’s educational writing shows intermingled pulses of domestic life, routines of educational bureaucracy, cycles of nature, and cataclysms of world events. It is important for historians to study “the where rather than just the when with location and landscape central parts of the analysis”.  相似文献

“劳动”这一概念在马克思的理论中具有举足轻重的地位,从“劳动”概念切入马克思的政治经济学批判是必要的,也是方便有效的。但是“劳动”在马克思不同的文本中往往具有不同的含义,仅仅在《1844年经济学哲学手稿》中,“劳动”就有两种用法,一种是中性的,另一种则是包含固有的消极规定在自身之内的,对于这一点应有所辨别,这对于我们合理使用马克思的文献具有重要意义。  相似文献

“The Bicycle Assembly Line Game” is a team‐based, in‐class activity that helps students develop a basic understanding of continuously operating processes. Each team of 7–10 students selects one of seven prefigured bicycle assembly lines to operate. The lines are run in real‐time, and the team that operates the line that yields the highest revenue wins. Students learn through discovery “What drives output rate?”; “How is capacity managed relative to market demand?”; and “Why does inventory accumulate?” Because task times are constant, the game provides a nice lead‐in to the topic of line balancing. This game has been successfully used in both undergraduate‐ and MBA‐level operations management courses.  相似文献

Improvement can fall into two main categories: technical based or people based. Consequently, improvement practitioners usually have specialized in one of these groups. They focus on either processes and products using what could be termed “hard or technical skills” (Lean Thinking, Six Sigma) or they focus on human behavior, using what could be termed “soft skills” (OD, HR Development). However, both skills are required to implement and sustain improvements.  相似文献

When evaluating equity, researchers often look at the “achievement gap.” Privileging knowledge and skills as primary outcomes of science education misses other, more subtle, but critical, outcomes indexing inequitable science education. In this comparative ethnography, we examined what it meant to “be scientific” in two fourth‐grade classes taught by teachers similarly committed to reform‐based science (RBS) practices in the service of equity. In both classrooms, students developed similar levels of scientific understanding and expressed positive attitudes about learning science. However, in one classroom, a group of African American and Latina girls expressed outright disaffiliation with promoted meanings of “smart science person” (“They are the science people. We aren't like them”), despite the fact that most of them knew the science equally well or, in one case, better than, their classmates. To make sense of these findings, we examine the normative practice of “sharing scientific ideas” in each classroom, a comparison that provided a robust account of the differently accessible meanings of scientific knowledge, scientific investigation, and scientific person in each setting. The findings illustrate that research with equity aims demands attention to culture (everyday classroom practices that promote particular meanings of “science”) and normative identities (culturally produced meanings of “science person” and the accessibility of those meanings). The study: (1) encourages researchers to question taken‐for‐granted assumptions and complexities of RBS and (2) demonstrates to practitioners that enacting what might look like RBS and producing students who know and can do science are but pieces of what it takes to achieve equitable science education. © 2011 Wiley Periodicals, Inc., Inc.

To determine the appropriate level of product availability, most operations management textbooks introduce and define service level measures in a Business‐to‐Customer context. In other words, a retailer that wants to measure product availability in their store calculates the fill rate (FR) or cycle service level over an infinite review horizon. However, in a Business‐to‐Business (B2B) context, a retailer almost always calculates the FR or compliance level over a finite review horizon. The goal of this article is to highlight calculations of service level measures in a B2B context. Pedagogically, it presents in‐class activities that use standard playing cards and/or a spreadsheet simulation that allow students to experientially learn about service level measures in a B2B context.  相似文献

Abstract

In this article two teacher educators describe an approach they have used with preservice early childhood and early childhood special education majors. They explain how the approach that they call “stories about teaching” resembles, yet differs from case study methods. The authors explain the process they used to develop, pilot, and use stories derived from qualitative data that they gathered in various early childhood settings. They explain how discussions based on the stories have provided their students opportunities to explore real‐life teaching situations from multiple perspectives, increase the depth of their reflections, and link theory to practice. © 2005 Elsevier Inc.

How did early childhood education become “risky” for children and teachers? This paper takes a series of booklets written in the 1990s as a case study of the entry of official anxiety about sexual abuse in early childhood centres in New Zealand. I argue that these documents provided a basis for policy development which reflects risk anxiety rather than a proper, informed appraisal of any real dangers to children in early childhood education in New Zealand; in addition, the documents legitimate unprecedented ongoing (self‐)regulation of teachers' practices, regulation about which critical questions cannot be asked without being understood as “denial” of abuse. It is concluded that the original documents, and the policies they engender, have had the negative and illegitimate effect of producing “risk of abuse” as a normal aspect of contemporary early childhood education.  相似文献

This recent study sought to examine the marketing orientations found in community, junior and technical colleges and to relate these orientations to enrollment trends within those same institutions. “High” and “low” marketing orientation campuses were defined based upon a marketing typology developed for the study. Analyses of variance revealed differences between these two types of campuses in terms of the stability of their full‐and part‐time headcount enrollments for a nine‐year period. Among other findings, the study describes the diversity of marketing approaches employed by the nation's two‐year colleges. Results of the study indicate that chief executives can look to establishing sound marketing management organizations, sensitive marketing intelligence systems, and efficient marketing planning and control systems to influence enrollment trends.  相似文献

A challenge facing many schools, especially those in urban settings that serve culturally and linguistically diverse populations, is a disconnection between schools and students' home communities, which can have both cognitive and affective implications for students. In this article we explore a form of “connected science,” in which real‐world problems and school‐community partnerships are used as contextual scaffolds for bridging students' community‐based knowledge and school‐based knowledge, as a way to provide all students opportunities for meaningful and intellectually challenging science learning. The potential of these scaffolds for connected science is examined through a case study in which a team of fifth‐grade teachers used the student‐identified problem of pollution along a nearby river as an interdisciplinary anchor for teaching science, math, language arts, and civics. Our analysis makes visible how diverse forms of knowledge were able to support project activities, examines the consequences for student learning, and identifies the features of real‐world problems and school–community partnerships that created these bridging opportunities. © 2001 John Wiley & Sons, Inc.

Many science educators encourage student experiences of “authentic” science by means of student participation in science‐related workplaces. Little research has been done, however, to investigate how “teaching” naturally occurs in such settings, where scientists or technicians normally do not have pedagogical training and generally do not have time (or value) receiving such training. This study examines how laboratory members without a pedagogical background or experience in teaching engage high school students during their internship activities. Drawing on conversation analysis, we analyze the minute‐by‐minute transactions that occurred while high school students participated in a leading environmental science laboratory. We find that the participation trajectory was based on demonstration‐practice‐connect (D‐P‐C) phases that continually recurred in the process of “doing” science. Concerning the transactional structures, we identify two basic conversation patterns—Initiate‐Clarify‐Reply (I‐C‐R) and Initiate‐Reply‐Clarify‐Reply (I‐R‐C‐R)—that do not only differ from the well‐known Initiate‐Reply‐Evaluate (I‐R‐E) patterns previously observed in science classrooms, but also could be combined to constitute more complex patterns. With respect to the organization of natural pedagogical conversations, we find that there were not only of preferred and dispreferred modes of responding but also ambiguous dispreferred modes; and the formulating organization not only includes self‐formulating but also other‐formulating. These natural pedagogical conversations helped, on the one hand, students to clarify their understanding and, on the other hand, technicians (or teachers) to teach toward different needs for different students in different contexts. © 2009 Wiley Periodicals, Inc.
