The relationship between inquiry-based teaching and students’ achievement. New evidence from a longitudinal PISA study in England
Publication date: June 2019Source: Learning and Instruction, Volume 61Author(s): John Jerrim, Mary Oliver, Sam SimsAbstractInquiry-based science teaching involves supporting pupils to acquire scientific knowledge indirectly by conducting their own scientific experiments, rather than receiving scientific knowledge directly from teachers. This approach to instruction is widely used among science educators in many countries. However, researchers and policymakers have recently called the effectiveness of inquiry approaches into doubt. Using nationally-representative, linked survey and administrative data, we find little evidence that the frequency of inquiry-based instruction is positively associated with teenagers’ performance in science examinations. This finding is robust to the use of different measures of inquiry, different examinations/measures of attainment, across classrooms with varying levels of disciplinary standards and across gender and prior attainment subgroups.
In conclusion, BLU-5937 was selected as a drug candidate for the treatment of chronic cough due to its high potency and selectivity for P2X3 homotrimeric receptors, strong anti-tussive effects, excellent tolerability and predicted pharmacokinetic properties in humans.
ConclusionThe SOS presents nearly as good as the SOFA score, to predict mortality among sepsis patients admitted to the ICU. The early warning score is another, alternative tool to use for risk stratification and sepsis screening for ICU sepsis patients.
Conclusions: Echogenicity of a pleural effusion has a low specificity for identifying an underlying exudate, and the echogenic qualities of the fluid should not influence clinical decision-making.Respiration
MRC Laboratory of Molecular Biology researchers reveal atomic structures of the abnormal tau filaments associated with chronic traumatic encephalopathy, a head injury-associated neurodegenerative disease, differ in structure from those seen in Alzheimer’s disease.
ConclusionsThese findings indicate that the neural effects of AUD vary according to severity. Our results emphasize the utility of resting state fMRI as a neuroimaging biomarker for quantitative clinical evaluation of AUD.

Schild, Thomas Klockgether, Henning BoeckerAbstractMany studies have used functional magnetic resonance imaging to unravel the neuronal underpinnings of motor system abnormalities in Parkinson's disease, indicating functional inhibition at the level of basal ganglia-thalamo-cortical motor networks. The study aim was to extend the characterization of functional motor changes in Parkinson's Disease by dissociating between two phases of action (i.e. m...
ConclusionsA clinically relevant model of PTA of venous stenosis in mice was created. PTA-treated vessels had increased lumen vessel area and WSS. The alterations in tissue markers of vascular remodeling, tissue hypoxia, proliferation, and cell death may be implications for future design of drug and device development.
ConclusionWEB shape modification was observed in more than half of cases but with no influence regarding adequate occlusion rate. This quantitative approach of WSM highlights that this phenomenon appears to be early and progressive over time. This supports the hypothesis that WSM could be more probably related to aneurysm healing rather than external compression.
