Virtual microscopy (VM) is a widely used teaching method in Medical Education in many developed countries. In Brazil, however, this is not the case for most medical schools, considering Brazilian social inequality and uneven access to technology. Recently, the Covid-19 pandemic has also challenged Universities to seek and make a transition toward more effective methods of full-time online education. Thus, the main goal of this work was to verify student's perception and academic performance, assessed upon VM implementation in a Brazilian Medical School. Ribeirao Preto Medical School students answered a 26-question survey with regards to optical microscopy (OM) and VM. Academic performance was compared between participants that were (year of 2019) or were not (year of 2015) exposed to VM. Taken the results together, subjective impressions such as handling, suitability, learning effectiveness, and pleasure using the tools, have shown a higher score for virtual microscopy (median = 29), when compared to optical microscopy (median = 24) with a P-value < 0.001 by Wilcoxon rank test, upon measurement using an ordinal scale. Regarding academic performance, no statistically significant differences were found between groups (P-value = 0.38, Cohen's d = 0.19). Therefore, VM proved to be adequate to the Brazilian medical education in light of Brazilian social contexts and Covid-19 pandemic.  相似文献   

The role of conceptual conflict in conceptual change and the design of science instruction   总被引：9，自引：0，他引：9  

Peter W. Hewson  Mariana G. A'Beckett Hewson 《Instructional Science》1984,13(1):1-13

Conceptual conflict has long been recognized as a factor that could facilitate student learning. Due, however, to the lack of a convincing explanation of why it occurs, and how it can be resolved, it has seldom been used in instructional design. Its potential use in instruction is particularly relevant in the light of the recent, well-documented finding that students' existing conceptions frequently constitute a barrier to effective learning. This article examines conceptual conflict in the light of an epistemological model of learning as conceptual change. This analysis shows that the conceptual change model provides an explanation of conceptual conflict which is sufficiently detailed to allow it to be used in the design of instruction. The results of two studies, the first of which addressed the concepts of mass, volume, and density, and the second, the concept of speed, show that instruction, designed in this way, is effective in changing students' existing conceptions.  相似文献   

The state and higher education in Colombia     

Ricardo Lucio  Mariana Serrano 《Higher Education》1993,25(1):61-72

The development of higher education in Colombia is discussed in terms of its recent quantitative expansion and the accompanying qualitative differentiation. Beginning in 1980 with the University Reform of that year, the state sought to give shape to the system by policies intended (i) to improve its organization (ii) to expand it on more democratic lines and (iii) to improve its quality. The authors discuss the developments which marked attempts to implement these aims. Two critical policy areas emerged—the funding of the system and the administration of the public sector part of it. Current debates are analysed and the authors provide pointers to possible future developments including the development of a highly stratified system with little interaction between the top and the bottom.  相似文献   

Metropolis revisited: the evolving role of librarians in informatics education for the health professions     

Samuel B. King  Mariana Lapidus 《Journal of the Medical Library Association》2015,103(1):14-18

Objective:

The authors'' goal was to assess changes in the role of librarians in informatics education from 2004 to 2013. This is a follow-up to “Metropolis Redux: The Unique Importance of Library Skills in Informatics,” a 2004 survey of informatics programs.

Methods:

An electronic survey was conducted in January 2013 and sent to librarians via the MEDLIB-L email discussion list, the library section of the American Association of Colleges of Pharmacy, the Medical Informatics Section of the Medical Library Association, the Information Technology Interest Group of the Association of College and Research Libraries/New England Region, and various library directors across the country.

Results:

Librarians from fifty-five institutions responded to the survey. Of these respondents, thirty-four included librarians in nonlibrary aspects of informatics training. Fifteen institutions have librarians participating in leadership positions in their informatics programs. Compared to the earlier survey, the role of librarians has evolved.

Conclusions:

Librarians possess skills that enable them to participate in informatics programs beyond a narrow library focus. Librarians currently perform significant leadership roles in informatics education. There are opportunities for librarian interdisciplinary collaboration in informatics programs.

Implications:

Informatics is much more than the study of technology. The information skills that librarians bring to the table enrich and broaden the study of informatics in addition to adding value to the library profession itself.  相似文献

From power‐machines to intelligent‐machines: A new education for a new technological era     

Mariana Belis 《International Journal of Science Education》2013,35(3):393-397

The technological revolution of our epoch is based upon a new kind of tool, the development and use of which requires not physical strength but higher education. The computer and its many industrial applications have completely changed technology, opening up new vistas for the participation of women in the labour force. An important problem raised by these changes is the technical education of both sexes. This paper discusses the experience acquired in Romania in this respect and the results obtained in the last decades.  相似文献   

Age is more than just a number! The role of age and maturity in the processes leading to early school leaving in Flanders (Belgium)          下载免费PDF全文

Lore Van Praag  Rut Van Caudenberg  Mariana Orozco 《British Educational Research Journal》2018,44(4):557-572

In many educational systems, age is used as a criterion to organise education. Children's age is used to group students together and indicate entry into particular programmes. The use of age for organisational purposes in education stems from the idea that age provides an indication of the development of children, which is associated with teaching and learning. However, more far‐reaching consequences of age‐related educational practices are insufficiently recognised in policy and academic research. Qualitative methods are used to study students and school personnel in diverse types of educational institutions in Flanders (Belgium) to assess how age and age‐related issues matter for the students’ educational trajectories and educational decision‐making processes leading to early school leaving. Data analyses reveal that school staff members consider age and perceived maturity during evaluation procedures. Students also consider age during educational decision‐making processes: when getting older or being too old for the grade, students increasingly weigh the costs and benefits associated with getting an educational qualification and being enrolled in school and alternative opportunities. Students’ expectations related to age shape their school experiences and feelings of belonging. The findings of this study demonstrate how these educational practices add to the reproduction of inequalities through education. These results could inform debates concerning the evaluation procedures in secondary education, compulsory education and the reduction of early school leaving in Europe.  相似文献   

Innovation in teacher education: towards a critical re-examination     

Viv Ellis  Mariana Souto-Manning  Keith Turvey 《师资教育杂志》2019,45(1):2-14

ABSTRACT

In the course of introducing a themed issue of the journal on “Innovation in Teacher Education’, we lay out an argument for re-examining the meaning of innovation in the field, shifting it away from the dominance of the economistic and technological. Acknowledging its status as a ‘buzzword’, we distinguish between purposes for innovation and, in particular, between changes driven by arguments for social mobility and those driven by social justice and equity. Two imperatives for innovation underpinned by arguments for social justice and equity are identified: the concept of a ‘teacher education debt’, built on Ladson-Billings’ more general notion of ‘education debt’; and the humanization of learning, teaching and becoming a teacher as person-centred, relational practices. The final section of the article introduces each of the six papers in the context of the discussion in previous sections about these imperatives for change.  相似文献   

Education of deaf students in Spain: legal and educational politics developments     

Fernández-Viader Mdel P  Fuentes M 《Journal of deaf studies and deaf education》2004,9(3):327-332

This article examines the legal instruments and educational politics affecting deaf persons' educational rights in Spain. We present a historical view of deaf education in Spain before and after the Congress of Milan (1880) and then introduce educational legislation and practices in recent decades. At present, Spanish legislation is moving toward recognition of sign languages and the suitability of bilingual education for deaf students at all educational levels. This is a consequence of taking into account the low academic achievement of two generations of deaf students educated in a monolingual model. Bilingual projects are now run throughout Spain. We emphasize that efforts must be made in the legal sphere to regulate the way in which professionals who know sign language and Deaf culture-teachers, interpreters, deaf adult models-are incorporated in bilingual deaf schools.  相似文献   

Short Report： Cyclic patterns of incidence rate for skin malignant melanoma： association with heliogeophysical activity     

Dimitrov BD  Rachkova MI  Atanassova PA 《Journal of Zhejiang University. Science. B》2008,9(6):489-495

Background: Our previous studies revealed cyclicity in the incidence rate of skin malignant melanoma (SMM; ICD9, Dx: 172) in the Czech Republic (period T=7.50～7.63 years), UK (T=11.00 years) and Bulgaria (T=12.20 years). Incidences com-pared with the sunspot index Rz (lag-period dT= 2, 4, 6, 10 or 12 years) have indicated that maximal rates are most likely to appear on descending slopes of the 11-year solar cycle, i.e., out of phase. We summarized and explored more deeply these cyclic variations and discussed their possible associations with heliogeophysical activity (HGA) components exhibiting similar cyclicity. Methods: Annual incidences of SMM from 5 countries (Czech Republic, UK, Bulgaria, USA and Canada) over various time spans during the years 1964～1992 were analyzed and their correlations with cyclic Rz (sunspot number) and aa (planetary geomagnetic activity) indices were summarized. Periodogram regression analysis with trigonometric approximation and phase-correlation analysis were applied. Results: Previous findings on SMM for the Czech Republic, UK and Bulgaria have been validated, and cyclic patterns have been revealed for USA (T=8.63 years, P<0.05) and Canada (Ontario, T=9.91 years, P<0.10). Also, various 'hypercycles' were established (T=45.5, 42.0, 48.25, 34.5 and 26.5 years, respectively) describing long-term cyclic incidence patterns. The association of SMM for USA and Canada with Rz (dT= 6 and 7 years, respectively) and aa (dT=-10 and 9 years, respectively) was described. Possible interactions of cyclic non-photic influences (UV irradiation, Schumann resonance signal, low-frequency geomagnetic fluctuations) with brain waves absorbance, neuronal calcium dynamics, neuro-endocrine axis modulation, melatonin/serotonin disbalance and skin neuro-immunity impairment as likely causal pathways in melanoma appearance, were also discussed. Conclusion: The above findings on cyclicity and temporal association of SMM with cyclic environmental factors could not only allow for better forecasting models but also lead to a better understanding of melanoma aetiology.  相似文献
