Impress your friends with mental Math tricks » Fun Math Blog See Math tricks on video at the Wild About Math! mathcasts page. Being able to perform arithmetic quickly and mentally can greatly boost your self-esteem, especially if you don't consider yourself to be very good at Math. And, getting comfortable with arithmetic might just motivate you to dive deeper into other things mathematical. This article presents nine ideas that will hopefully get you to look at arithmetic as a game, one in which you can see patterns among numbers and pick then apply the right trick to quickly doing the calculation. The tricks in this article all involve multiplication. Don't be discouraged if the tricks seem difficult at first. As you learn and practice the tricks make sure you check your results by doing multiplication the way you're used to, until the tricks start to become second nature. 1. Multiplying by 9 is really multiplying by 10-1.So, 9x9 is just 9x(10-1) which is 9x10-9 which is 90-9 or 81. Let's try a harder example: 46x9 = 46x10-46 = 460-46 = 414. 2. 3.

Critical thinking | Learning resources | Institute for Academic Development Advice and resources on the subject of critical thinking. Why is being critical important? It affects your academic success: if you wish to achieve higher grades, being able to take an informed and analytical approach to your studies is very important. Simply memorising and explaining concepts and ideas will not be sufficient for a strong pass at masters level. You need to be able to demonstrate knowledge of your subject and give your opinion(s) supported by evidence that you have judged to be appropriate. It affects your employability: one of the main reasons students undertake postgraduate study is to improve their employment prospects. What do we mean by ‘critical’? Being ‘critical’ does not mean just being negative, or pointing out what is wrong about something. You can find out more about the framework at : SCQF level descriptors (PDF) Taking a critical approach in your studies and professional development can include behaviours such as: Critical thinking ‘stairway’ Further reading
Physics Flash Animations We have been increasingly using Flash animations for illustrating Physics content. This page provides access to those animations which may be of general interest. The animations will appear in a separate window. The animations are sorted by category, and the file size of each animation is included in the listing. In addition, I have prepared a small tutorial in using Flash to do Physics animations. LInks to versions of these animations in other languages, other links, and license information appear towards the bottom of this page. The Animations There are 99 animations listed below. Other Languages and Links These animations have been translated into Catalan, Spanish and Basque: En aquest enllaç podeu trobar la versió al català de les animacions Flash de Física. Many animations have been translated into Greek by Vangelis Koltsakis. Most animations have been translated into Hungarian by Sandor Nagy, Eötvös Loránd University.
Practical Physics This website is for teachers of physics in schools and colleges. It is a collection of experiments that demonstrate a wide range of physical concepts and processes. Some of the experiments can be used as starting-points for investigations or for enhancement activities. Many have links to carefully selected further reading and all include information and guidance for technicians. Physics is a practical science. Practical activities are not just motivational and fun: they can also sharpen students’ powers of observation, stimulate questions, and help develop new understanding and vocabulary. Good quality, appropriate physics experiments and investigations are the key to enhanced learning, and clarification and consolidation of theory. We have published a new set of resources to support the teaching of practical science for Key Stages 3-5.
Critical reading techniques You will probably find that there is a lot of reading required for your module. Like many students, you might find that you are time-poor and you will, therefore, need to be speedy and efficient in your reading.

According to Beyer (1995) Critical thinking means making clear, reasoned judgements. While in the process of critical thinking, ideas should be reasoned and well thought out/judged.[1] The National Council for Excellence in Critical Thinking defines critical thinking as the intellectually disciplined process of actively and skillfully conceptualizing, applying, analyzing, synthesizing, and/or evaluating information gathered from, or generated by, observation, experience, reflection, reasoning, or communication, as a guide to belief and action.'[2] Etymology[edit] In the term critical thinking, the word critical, (Grk. κριτικός = kritikos = "critic") derives from the word critic, and identifies the intellectual capacity and the means "of judging", "of judgement", "for judging", and of being "able to discern".[3] Definitions[edit] According to the field of inquiry [weasel words], critical thinking is defined as: Skills[edit] In sum:
Science Game FRAN SCOTT demos & pracs 5 Fun Science Experiments for Kids Everyone knows science is awesome, but did you know you can do science right in your own kitchen? Ok, maybe you did, but if you're not sure where to start, we've got five really fun experiments that demonstrate the scientific principles of buoyancy, surface tension, density, chemical reaction and non-Newtonian fluid. Best of all, families can do these easy experiments with common, household items. Sesame Street's fuzzy, blue scientist Grover stopped by the #5facts studio to teach us a few things about the scientific method. Watch the adorable video above to see the experiments in action, then use the instructions below to gather everything you need for your home science lab.
