Induced in incorrect generalizations leading to misconceptions—an exploratory investigation about the laws of reflection of light     

J. K. Mohapatra 《科学教学研究杂志》1988,25(9):777-784

The phenomena of induced incorrect generalization (IIG) as a generative cause for the formation of a misconception among a group of pupils is identified. In the process of learning the laws of reflection of light the effect of IIG is discussed through an exploratory experiment. Strategies are suggested to eliminate the formation of such IIG in a classroom situation.  相似文献   

The visual rhetoric of the aerial view: From surveillance to resistance     

Eli B. Mangold 《Quarterly Journal of Speech》2019,105(1):25-41

We live in a world increasingly photographed from satellites, planes, and drones. Many scholars have viewed aerial imagery through a dystopian lens, largely due to its use by the state and its legacy of military applications. While problematic uses of aerial images persist, this paper theorizes rhetorical potentialities of aerial imagery. We posit how aerial imagery creates these potentialities through strategies related to questions of visibility, scale, and aesthetics. Using case studies that illuminate these strategies, we demonstrate how they can be used to resist state and corporate interests, constitute new social movements, and invite contemplation of otherwise repellent political subject matter. Ultimately, we argue that with increased technological access and the ability to reconfigure norms of expertise, the aerial view presents both opportunities for civic engagement and counter-hegemonic potential.  相似文献   

Bridging Research and Practice: How Sales Training Can Contribute to New Product Launch Success     

Frank Q. Fu  Eli Jones 《Performance Improvement》2015,54(2):29-36

This study demonstrates how academicians and practitioners can work together on an important topic that matters to organizational performance: the pivotal role played by salespeople during new product launches. In particular, the authors present three potential interventions that training and sales managers may use to sell a new product to salespeople. The results legitimatize the critical contribution of sales training to new product sales performance and highlight the value of the partnership between training professionals and sales managers.  相似文献

Serum total PSA and free PSA in breast tumors     

Dash P  Pati S  Mangaraj M  Sahu PK  Mohapatra PC 《Indian journal of clinical biochemistry : IJCB》2011,26(2):182-186

Now a days measurement of molecular forms of PSA has gained importance in clinical practice. Several studies have demonstrated the production of PSA in female tissues, such as breast. The present piece of work has been undertaken with an objective to estimate the relative proportion of the molecular forms of PSA in serum along with serum testosterone in benign and malignant breast tumor cases and to analyze their association with the severity of the disease process 34 malignant and 26 benign breast disease cases along with 33 healthy controls of same age group were enrolled in this study for evaluation. Serum testosterone was measured by ELISA, whereas serum total PSA (TPSA) and free PSA (FPSA) were estimated by electrochemiluminescence immunoassay. A significant rise of fasting plasma glucose along with prominent dyslipidemia was observed in breast tumor cases. Marked rise in serum testosterone as well as TPSA and FPSA was documented in both benign and malignant breast tumor cases. Serum testosterone revealed a significant positive association with both TPSA and FPSA pointing towards an etiological association between them. However, surgical removal of tumor mass resulted in a marked decline of presurgical value of both TPSA and FPSA with a non-significant fall in serum testosterone revealing tumor tissue as the source of FPSA and TPSA. Thus, estimation of PSA provides prognostic information that may assist in future treatment.  相似文献   

REFLECTIONS ON A CAREER IN JEWISH EDUCATION     

Eli Grad 《Journal of Jewish Education》2013,79(1):14-17

My vision of Jewish education assumes the critical importance of finding not only better methodologies and curricula but also more highly motivated and better-trained staff. Yet, even with such an assumption, the ultimate need is for religious schools to “connect” in the deepest sense: to connect with the family as much as with the student; to connect with the students' perceptions of the world they know, so that Jewish learning does not seem to be totally alien to their lives; and to connect with a sense of the overall vibrancy of the synagogue as the center of Jewish life.  相似文献   

DiaspoRican Art as a Space for Identity Building,Cultural Reclamation,and Political Reimagining     

Enid M. Rosario-Ramos  Eli Tucker-Raymond  Maria Rosario 《Journal of Latinos & Education》2017,16(3):217-228

The lives of Puerto Ricans in the neighborhood of Humboldt Park, Chicago, are often situated in a complex social field shaped by transnational cultural and political border crossing. We argue that artistic practices in this neighborhood are integral to building community and individual identities grounded in local meanings of the Puerto Rican diaspora experience. Interviews with three adolescent community residents and a high school art teacher indexed themes that exemplify community residents’ purposes for artistic practice: (1) self-expression within practices of collective identity building; (2) cultural reclamation; and (3) political reimagining. We also discuss how such work invites new tensions for identity making, including who can participate, who is represented, and what forms those representations take. These tensions point backward in time, forward to the future, and across geopolitical space. Finally, we suggest implications for learning in schools.  相似文献

Tin(Sn)-based perovskite solar cells(PSCs) have received increasing attention in the domain of photovoltaics due to their environmentally friendly nature.In this paper,numerical modeling and simulation of hole transport material(HTM)-free PSC based on methyl ammonium tin triiodide(CH₃NH₃SnI₃) was performed using a one-dimensional solar cell capacitance simulator(SCAPS-1D) software.The effect of perovskite thickness,interface defect density,temperature,and electro...  相似文献   

An integrative and holistic engineering education     

Joseph Bordogna  Eli Fromm  Edward W. Ernst 《Journal of Science Education and Technology》1995,4(3):191-198

The several reports and papers of the past decade suggesting paradigm shifts in engineering education are shown to reveal a common theme, to wit: engineering is an integrative process, and thus engineering education, particularly at the baccalaureate level, should be designed toward that end. Suggesting a change in intellectual culture, the roots of contemporary collegiate education in the United States are traced to their origin and attention is given to discussing the current emphasis on reductionism vis-à-vis integration or, said another way, a course-focused education compared to a more holistic approach in which process and knowledge are woven throughout the curriculum. A new construct for systemic change in baccalaureate engineering education is suggested in terms of a taxonomy of intellectual components connected holistically with a core focus on developing human potential, as opposed to the present system in which students are passed serially through course filters.An early version of this work appeared as Engineering education: Innovation through integration,Journal of Engineering Education 82(1): 3–8, 1993.  相似文献
