Beyond Pisa 2015: a Longer-term Strategy of Pisa

d) PISA assesses both subject matter content knowledge, on the one hand, and the capacity of individuals to apply that knowledge creatively, including in unfamiliar contexts, on the other. Until now PISA has assessed students in three main domains in each round: reading, mathematics and science. These domains cover some of the fundamental skills needed to continue on with higher education or su...

The PISA method simplified.

We have read with interest the study by Messika-Zeitoun et al. 1 showing that using a fixed angle value of 100 provides an accurate estimation of the miral valve area (MVA) by the proximal isove-locity surface area (PISA) method in patients with mitral stenosis (MS). We appreciate the study as a means to make PISA method more popular in assessing the MVA. Although not cited in the article, we a...

Panel Estimates from PISA

—— An extreme low power voltage reference generator operating with a supply voltage ranging from 0.9 to 4 V has been implemented in AMS 0.35 μm CMOS process. The maximum supply current measured at the maximum supply voltage and at 80 °C is 70 nA. A temperature coefficient of 10 ppm/°C is achieved by means of a perfect suppression of the temperature dependence of the mobility, the compensation o...

Learning from PISA

The great competition is over, the judges have given their marks and the chalk dust has settled over the arena. A few hurt prides pick themselves up off the floor, and set about the painful task of finding out what went wrong and why they did not fare as well as they expected. This is not the aftermath of the winter Olympics, rather the results of the PISA study, the Programme for International...
