How good are interior point methods? Klee–Minty cubes tighten iteration-compl...SSA KPI

The passage discusses Deborah Mayo's philosophy of science, which focuses on rigorously validating claims made through experimentation. According to Mayo, a claim can only be considered supported by an experiment if the experiment investigates and eliminates all possible ways the claim could be false. For an experiment to serve as a severe test of a claim, the claim would have to be unlikely to pass the experiment if it were false. The passage provides examples to illustrate this point, such as how imprecise measurements of Snell's law of refraction would allow alternative historical laws to also seem consistent with the experimental results, demonstrating the experiment was not a true severe test of Snell's law.

A Strategic Approach: GenAI in EducationPeter Windle
Artificial Intelligence (AI) technologies such as Generative AI, Image Generators and Large Language Models have had a dramatic impact on teaching, learning and assessment over the past 18 months. The most immediate threat AI posed was to Academic Integrity with Higher Education Institutes (HEIs) focusing their efforts on combating the use of GenAI in assessment. Guidelines were developed for staff and students, policies put in place too. Innovative educators have forged paths in the use of Generative AI for teaching, learning and assessments leading to pockets of transformation springing up across HEIs, often with little or no top-down guidance, support or direction.
This Gasta posits a strategic approach to integrating AI into HEIs to prepare staff, students and the curriculum for an evolving world and workplace. We will highlight the advantages of working with these technologies beyond the realm of teaching, learning and assessment by considering prompt engineering skills, industry impact, curriculum changes, and the need for staff upskilling. In contrast, not engaging strategically with Generative AI poses risks, including falling behind peers, missed opportunities and failing to ensure our graduates remain employable. The rapid evolution of AI technologies necessitates a proactive and strategic approach if we are to remain relevant.
