PlayingCLIL, a new game-based methodology using drama pedagogy

[EN]Linguistic immersion programs are increasing nowadays. The concept of being bilingual, that started being used by schools for the elite in the 19th century, and that in the mid- 20th century became an educational option, has given raise to CLIL (Content and Language Integrated Learning), a methodology through which students work in a bilingual environment, acquiring knowledge of curricular subject and developing their competences in a foreign language. In this teaching context started a new European project called PlayingCLIL. Six partners from different European countries (Germany, United Kingdom, Spain and Romania) are working in this project. Our main aim is to develop a new methodology to learn a foreign language combining elements from the pedagogic drama (interactive games) with the CLIL classroom. At present we are testing the games in different schools and high schools and we are compiling the results to be collected in a handbook (printed and e-book).

Arterial O2 content and tension in regulation of cardiac output and leg blood flow during exercise in humans

[EN] A universal O2 sensor presumes that compensation for impaired O2 delivery is triggered by low O2 tension, but in humans, comparisons of compensatory responses to altered arterial O2 content (CaO2) or tension (PaO2) have not been reported. To directly compare cardiac output (QTOT) and leg blood flow (LBF) responses to a range of CaO2 and PaO2, seven healthy young men were studied during two-legged knee extension exercise with control hemoglobin concentration ([Hb] = 144.4 +/- 4 g/l) and at least 1 wk later after isovolemic hemodilution ([Hb] = 115 +/- 2 g/l). On each study day, subjects exercised twice at 30 W and on to voluntary exhaustion with an FIO2 of 0.21 or 0.11. The interventions resulted in two conditions with matched CaO2 but markedly different PaO2 (hypoxia and anemia) and two conditions with matched PaO2 and different CaO2 (hypoxia and anemia + hypoxia). PaO2 varied from 46 +/- 3 Torr in hypoxia to 95 +/- 3 Torr (range 37 to >100) in anemia (P < 0.001), yet LBF at exercise was nearly identical. However, as CaO2 dropped from 190 +/- 5 ml/l in control to 132 +/- 2 ml/l in anemia + hypoxia (P < 0.001), QTOT and LBF at 30 W rose to 12.8 +/- 0.8 and 7.2 +/- 0.3 l/min, respectively, values 23 and 47% above control (P < 0.01). Thus regulation of QTOT, LBF, and arterial O2 delivery to contracting intact human skeletal muscle is dependent for signaling primarily on CaO2, not PaO2. This finding suggests that factors related to CaO2 or [Hb] may play an important role in the regulation of blood flow during exercise in humans.
