Web geometry laboratory: case studies in Portugal and Serbia     

Vanda Santos  Milena Marić  Helena Campos 《Interactive Learning Environments》2018,26(1):3-21

The role of information and communication technologies (ICT) in education is well recognised – learning environments where the ICT features included are being proposed for many years now. The Web Geometry Laboratory (WGL) innovates in proposing a blended learning, collaborative and adaptive learning Web-environment for geometry. It integrates a well-known dynamic geometry system providing an adaptive environment where face-to-face activities can be combined with computer-mediated activities, in a collaborative or stand-alone, synchronous or asynchronous, classroom or homework way. The WGL collaborative environment allows each student to capitalise on one another's resources and skills. Its adaptive module gives to each teacher the ability to assess the geometric level of each student, allowing the teacher to build the individual profile and/or learning paths. In this paper we begin describing what are the goals that support the development of such an environment, the goals that support our beliefs in the usefulness of such an environment for the teaching and learning of geometry, after which we describe the environment and the case studies already conducted.  相似文献   

Attitudes towards inclusion in higher education in a Portuguese university     

Maria Helena Martins  Maria Leonor Borges  Teresa Gonçalves 《International Journal of Inclusive Education》2018,22(5):527-542

In this article, we present data concerning the inclusion of students with disabilities in higher education (HE) at a Portuguese university. This research is part of a wider project designed to understand the trajectories and experiences of students with disabilities at the University of Algarve. This exploratory study raises questions about inclusion and discusses this concept based on the perspectives of academic and non-academic staff. A qualitative approach was used to provide an informative exploration of attitudes towards inclusive education and recommendations for promoting best practices therein. Data were collected using semi-structured interviews. We found positive perceptions of university staff members about the inclusion of the students with disabilities. However, more effort is needed to provide these students with opportunities to continue their academic career in HE and to promote inclusion, personal development and participation in social and economic life. Although inclusive education is on political and educational agendas, the perception of disabilities as deficits prevails. The findings of this study, therefore, reveal that changes must be implemented to effectively adopt the social and educational model of disability.  相似文献   

‘Freer’ Forms of Organization and Financing and the Effects of Inequality in Latin American Educational Systems: two countries in comparison     

Helena Munín 《Compare》1998,28(3):229-243

The introduction of ‘freer’ forms of organization and financing into the Latin American educational systems about 20 years ago parallels similar developments in the contexts of neo‐liberal policies in the USA, Great Britain and, more recently, in Eastern Europe. This article will highlight the effects of ‘school autonomy’, decentralization, and privatization in the Latin American educational systems. In so doing, I will focus on the analysis of educational policy development in Chile and Argentina, based in part on my own research results. The results demonstrate that ‘freer’ forms of organization and financing have not proven to be positive for the progressive distribution of education, democratization and the consideration of diversity—and also not for the (difficult to measure) categories of ‘quality’ and ‘efficiency’ of education. These findings contribute to question whether the neo‐liberal forms of organization and financing of educational systems in Latin America are important factors in the realization of these goals.  相似文献   

Verification of Atellica 1500 and comparison with Iris urine analyser and urine culture     

Ana Nikler  Helena i ak  Danijela Bejuk  Vanja Radi&#x;i&#x; Biljak  Ana-Maria &#x;imundi&#x; 《Biochemia medica : ?asopis Hrvatskoga dru?tva medicinskih biokemi?ara / HDMB》2022,32(1)

IntroductionThe aims of study were to assess: 1) performance specifications of Atellica 1500, 2) comparability of Atellica 1500 and Iris, 3) the accuracy of both analysers in their ability to detect bacteria.Materials and methodsCarryover, linearity, precision, reproducibility, and limit of blank (LoB) verification were evaluated for erythrocyte and leukocyte counts. ICSH 2014 protocol was used for estimation of carryover, CLSI EP15-A3 for precision, and CLSI EP17 for LoB verification. Comparison for quantitative parameters was evaluated by Bland-Altman plot and Passing-Bablok regression. Qualitative parameters were evaluated by Weighted kappa analysis. Sixty-five urine samples were randomly selected and sent for urine culture which was used as reference method to determine the accuracy of bacteria detection by analysers.ResultsAnalytical specifications of Atellica 1500 were successfully verified. Total of 393 samples were used for qualitative comparison, while 269 for sediment urinalysis. Bland-Altman analysis showed statistically significant proportional bias for erythrocytes and leukocytes. Passing-Bablok analysis for leukocytes pointed to significant constant and minor proportional difference, while it was not performed for erythrocytes due to significant data deviation from linearity. Kappa analysis resulted in the strongest agreements for pH, ketones, glucose concentrations and leukocytes, while the poorest agreement for bacteria. The sensitivity and specificity of bacteria detection were: 91 (59-100)% and 76 (66-87)% for Atellica 1500 and 46 (17-77)% and 96 (87-100)% for Iris.ConclusionThere are large differences between Atellica 1500 and Iris analysers, due to which they are not comparable and can not be used interchangeably. While there was no difference in specificity of bacteria detection, Iris analyser had greater sensitivity.  相似文献
