Applying the Collective Causal Mapping Methodology to Operations Management Curriculum Development*     

Julie M. Hays  Tatiana Bouzdine‐Chameeva  Susan Meyer Goldstein  Arthur V. Hill  Annibal Jos Scavarda 《Decision Sciences Journal of Innovative Education》2007,5(2):267-287

Although the field of operations management has come a long way since its beginnings in scientific management, the field still appears somewhat amorphous and unstructured to many. Introductory operations management textbooks usually include a number of largely disjointed topics, which leave many students (and their instructors) without a coherent framework for understanding the field. As a result, the importance and sequencing of topics varies widely between courses and instructors, even within the same university. This article applies the newly developed Collective Causal Mapping Methodology to create a causal map for the entire field of operations management. The causal map is built on expert opinions collected from over 250 academics and practitioners representing many areas of expertise, schools, organizations, and countries. This collective causal map is then used to create a new framework for understanding and teaching operations management. This framework can aid instructors in determining which topics should be taught in an operations management course, how these topics might be grouped and sequenced, and the important interrelationships among the topics that should be stressed to students.  相似文献   

The Methodological Challenges of Measuring Student Learning,Degree Attainment,and Early Labor Market Outcomes in Higher Education     

Tatiana Melguizo  Gema Zamarro  Tatiana Velasco  Fabio J. Sanchez 《Journal of research on educational effectiveness》2017,10(2):424-448

The main objective of this study is to empirically test a number of theory-based models (i.e., fixed effects [FE], random effects [RE], and aggregated residuals [AR]) to measure the generic knowledge as well as the degree attainment rates and early labor outcomes gained by students in different programs and institutions in higher education. Our results show the importance of addressing the issue of student selection into programs and institutions in order to reduce selection bias, and they provide suggestive evidence in favor of using FE models. Our findings also confirm our hypotheses that rankings of specific college-program combinations change depending on the different educational and labor outcome measures considered. This finding emphasizes the need to use complementary indicators related to the mission of the specific postsecondary institutions that are being ranked. Given the sensitivity of the models to different model specifications, it is not clear whether they should be used to make any high-stakes decisions in higher education. They could, however, serve as part of a broader set of indicators to support programs and colleges as part of a formative evaluation.  相似文献   

Improving student outcomes in high‐enrollment statistics classes with the structured writing approach     

Tatiana Batova  Stefan Ruediger 《Teaching Statistics》2019,41(3):94-100

The article describes an assignment that makes writing‐to‐learn feasible in high‐enrollment statistics classes. It combines the principles of structured writing with Bloom's taxonomy. The assignment helped improve related exam scores and was easy to implement and grade for instructors.  相似文献

The Earnings Benefits of Majoring in STEM Fields Among High Achieving Minority Students     

Tatiana Melguizo  Gregory C. Wolniak 《Research in higher education》2012,53(4):383-405

The purpose of this study was to improve our understanding of the association between major field of study in college and early career earnings among a sample of academically accomplished minority students. Results demonstrate the economic benefits minority students experience from majoring in a Science, Technology, Engineering and Math field during college, and highlight the importance of gaining employment in a closely related field in order to secure those benefits. The results also illustrate the need to carefully account for self-selection when estimating the earnings premiums in relation to educational experiences during college. Implications for policy and research are discussed.  相似文献   

The Benefits of Improved Information Literacy Skills on Student Writing Skills: Developing a Collaborative Teaching Model with Research Librarians in Undergraduate Social Work Education     

Laura Brierton Granruth  Tatiana Pashkova-Balkenhol 《Journal of Teaching in Social Work》2013,33(5):453-469

Improving the information literacy and writing skills of undergraduate social work students continues to be an issue for social work educators. In spite of the persistent concern, only a few studies examine the factors influencing these skills and interventions to strengthen them. This article details a faculty–librarian collaborative teaching model to develop students’ information literacy and writing skills through an iterative, peer-reviewed process that includes online and in-class library instruction. Pre- and posttest results from course evaluations, using the learning management system, indicate that students improve their information literacy skills, which in turn improves their writing skills. The article concludes with a discussion of implications for academic and professional development.  相似文献

Effects of differently polarized microwave radiation on the microscopic structure of the nuclei in human fibroblasts     

Yuriy G. Shckorbatov  Vladimir N. Pasiuga  Elena I. Goncharuk  Tatiana Ph. Petrenko  Valentin A. Grabina  Nicolay N. Kolchigin  Dmitry D. Ivanchenko  Victor N. Bykov  Oleksandr M. Dumin 《Journal of Zhejiang University. Science. B》2010,11(10):801-805

To investigate the influence of microwave radiation on the human fibroblast nuclei, the effects of three variants of electromagnetic wave polarization, linear and left-handed and right-handed elliptically polarized, were examined. Experimental conditions were: frequency (f) 36.65 GHz, power density (P) at the surface of exposed object 1, 10, 30, and 100 μW/cm², exposure time 10 s. Human fibroblasts growing in a monolayer on a cover slide were exposed to microwave electromagnetic radiation. The layer of medium that covered cells during microwave exposure was about 1 mm thick. Cells were stained immediately after irradiation by 2% (w/v) orcein solution in 45% (w/v) acetic acid. Experiments were made at room temperature (25 °C), and control cell samples were processed in the same conditions. We assessed heterochromatin granule quantity (HGQ) at 600× magnification. Microwave irradiation at the intensity of 1 μW/cm² produced no effect, and irradiation at the intensities of 10 and 100 μW/cm² induced an increase in HGQ. More intense irradiation induced more chromatin condensation. The right-handed elliptically polarized radiation revealed more biological activity than the left-handed polarized one.  相似文献   

Toddlers’ peer engagement in Swiss childcare: contribution of individual and contextual characteristics     

Diebold  Tatiana  Perren  Sonja 《European Journal of Psychology of Education - EJPE》2022,37(3):627-648

The present study observed 86 three-year-old children (M = 43.7, SD = 6.4) from 15 Swiss childcare groups, to investigate multiple individual and contextual contributions to toddlers’ positive engagement with peers. The children’s individual characteristics (age, sex and social skills) and childcare-related predictors (emotional and behavioural support from caregivers, and structural group features) were assessed. We employed the child-by-environment perspective and tested the hypothesis that high-quality behavioural and emotional support provided by caregivers benefits children with deficits in social abilities. Results of the multilevel structural equation modelling indicated that toddlers rated by caregivers as sociable and assertive showed more positive situation-specific peer engagement, especially with a concomitant higher quality of caregiver emotional and behavioural support. By contrast, being prosocial-cooperative was negatively associated with observed peer engagement. Thus, children’s social skills were found to be the most important factor for peer engagement in childcare settings. Important suggestions for future research are made, and practical implications are discussed.
