Stunning CT scanner art
Satre Stuelke is an artist and medical student who uses a CT scanner to examine every-day objects in a new way. CT scanners are normally intended for medical imaging, but by using them to create art and inviting others to join him, Stuelke hopes to “plant a seed of scientific creativity in the minds of all those inclined to participate.” I quite like this image of a set of Russian nested dolls:
Science exams are slipping
Ofqual, the government body that regulates examinations, has said that an investigation in to the standard of teaching in GCSE science has “raised significant causes for concern.” It said that the exams are not up to standards, and do not offer enough of a challenge to the most able students. The following recommendations were made:
- Improved quality of questions, to stretch and challenge all students
- Work, including further training for senior examiners, to improve the quality of objective tests
- Tighter marking criteria to ensure that only the answers deserving of the marks are credited
- Some internal assessment tasks have been revised to ensure better challenge to students and a closer link to the practical work. These changes took effect from last September.
- Where possible within the existing specifications, the number of options available to candidates has been reduced.
It’s vital that we keep exam standards high. Ofqual said that mathematics and English literature exams are maintaining their quality, so why has science been allowed to slip?
