Perpetual motion definition11/22/2023 ![]() ![]() They conclude that whilst learning style theorists have conducted small-scale, weakly controlled studies to support their claims, none of them produce systems with any clear evidence that using them will advantage learners. They found that whilst a few of the them provided some relatively valid measures of differences between people, none of them demonstrated that attempting to match teaching to this style would have any benefit. Certainly, all of the systems have tried to define learning styles, but the question is whether any of them actually work. The idea at the heart of learning styles is that information provided to a student in a form that matches their ‘style of learning’ will lead to improved learning.Ĭoffield et al (2004) review over a dozen attempts to measure differences in learning ability so that instruction can be matched to this ‘style of learning’. I recently read a short series of blogs defending the idea of ‘learning styles’. I’d certainly accept that they have tried to create a perpetual motion machine (and thus far failed), or created a machine which they claimed possessed perpetual motion (but didn’t really) – but to say that perpetual motion machines ‘exist’ surely implies that someone has built one that actually works. It would be very, very odd for someone to claim that they did exist, simply because inventors periodically try to create one. Perpetual motion machines do not exist, because no one has built a machine which can continue indefinitely without some external source of energy to keep it going. However, no attempt to create one has ever worked. The failure to build such a machine hasn’t stopped people from trying to build them or even applications for patent whether using magnets, or gravity or buoyancy as the basis for perpetual motion. The idea of creating a machine which can continue indefinitely without any source of energy to power it is one that has fascinated inventors since the astronomer and mathematician Bhāskara II described a wheel which could run forever in the 12 th century. The idea involved water held in a tank above the apparatus driving a water wheel which, through a complex set of gears, rotate an Archimedes screw which draws the water back up to the water tank.
