The Science and Psychology of Physical Skills Training
Posted by admin in Physical Science, Psychology on November 15, 2011
When training staff in the use of physical force it is important that the techniques provided enable staff to achieve the desired outcome, i.e., the physical control of an individual with minimal risk to all concerned or the successful defence of a person likely to be attacked. Therefore, it is fundamentally important that the physical skills taught to staff complement their ability to achieve the desired effect.
Physical use of force, like any other physical activity, requires the use of various physical motor skills. Motor skills can be defined as movements that are performed with a desired goal in mind. In sporting environments this may mean achieving such aims as holding a handstand in gymnastics. In physical restraint it means achieving the aim of staff being able to use a technique to physically control a violent person whilst reducing the harm to them and to others, and in self-defence it is the ability to defend oneself quickly and effectively..
The balance therefore in developing any system of self defence or physical restraint must be to make staff effective by the efficient use of skill and energy by designing skills and techniques that achieve their desired objective in real operational situations. Read the rest of this entry »
How to Solve a Physical Science Problem
Posted by admin in Physical Science on November 15, 2011
Solving problems in physical sciences or in mathematics can cause great difficulty for some students. If you feel the same way, maybe the steps below might help. You might up to now have been learning from your teacher how to ‘do’ a particular question and then finding yourself stuck when you come across a new one with a slight variation. What you need to develop is a general way of dealing with mathematical problems in science, so that you won’t be dependent on any one set of questions.
Never leave a blank space! Even if you “can’t do the question”, you can carry out most of the steps below, and quite often you’ll find the answer in the process. You can’t give up until you’ve tried these steps. Practice them, so you can do them quickly.
1. Read the question twice. Get the gist of what it’s about. Understand what is being asked of you.
2. Read it again more slowly. Find out what information you are given. If there are specific values given, give them a name, and a symbol and write them down as you find them. Read the rest of this entry »
