The programme introduces a pedagogical model aimed to foster exploratory and collaborative learning through the use of computational tools. In this article, we present some results from an evaluation study that looked at teachers' practice with these tools, their assimilation of the pedagogical model and the impact of the use of the programme on students' learning. The results show that teacher-training remains insufficient and that teachers have great difficulties in changing their practice as conceived by the programme. The use of the technological tools in schools is also very inconsistent. For students, the benefit of the technology-based activities remains difficult to assess, and there is no visible impact on learning as measured by items used in national evaluations (although there seems to be a correlation between the tools used and the learning of different mathematical topics).

We report a patient with membranoproliferative glomerulonephritis, type III circulating cryoglobulins and hepatitis C virus infection with detection of HCV RNA in serum, cryoprecipitate and renal tissue using specific RT-PCR technique. These data confirm that HCV could have a direct role in renal damage.

Commonly localized in the jugular venous system, although it can turn-up, the ectasia, to other cervicofacial veins. In this paper are reported 3 neck phlebectasis including one of them affecting the anterior facial vein, occurrence exceedingly uncommon, of which case we don't know even a single reference in the literature. We make a perusal of the subject's bibliography and also discuss the clinic, diagnostic and therapeutical most important features of this entity.

Each dialogue mode is characterized by the praxeological elements that are taken as starting points: the kind of scientific problems dealt with; the theoretical component and WKH�≥PHWKRGRORJLFDO¥�FRPSRQ - ent, which includes research techniques and technologies. The last two dialogue modes between APOS theory and ATD are illustrated, stressing those aspects of each theory that can be promoted and developed.
