In these pages of definitions we aim to impart the facts. Indeed reviewing them every now and then it is sometimes strange how the facts tend to be permanent and other smaller details can change without warning. So we thought we'd include this. Obviously a teacher is one who imparts the knowledge and skills to the student/s. Teaching has been a mainstay of modern life from as early as the Ancient Greek Civilisation and before. One of the unescapable elements of the teaching is the text books. There is also a rich history with various accounts of parchment and the like of textual material dating back to the Ancient Egyptian civilisation in Northeast Africa. One of the more significant milestones was the utilisation of the spine which enabled the reader to gain a general description of what that particular publication was about while it's on the shelf. Early schools of thought also included the philosophies of Socrates and Plato and the mathematics of Pythagoras. Of course the tools for teachers and students comprise of the traditional stuff of life, namely pen and paper, however in recent times these seem to be deprecating slowly in favour of other low end powered technological devices. Obviously there are methods of reading and writing with these devices, moreover it is questionable whether we could use those devices in the same way as pen and paper. For one thing, a well looked after book, folder, or essay on paper can last a very long time. With respect to digital devices, it is the proliferation of alternative uses which make it a generally non uniform mode of thought. The components in these devices are geared towards various custom procedures and as these need to be created, we can assume that the technologies are at best for 'creative' purposes. Additionally, with respect to digital devices, they often conform to the waterfall life cycle model which is periodically updated and renewed regularly. Although it is comforting that the Amazon Kindle has remained worthy. After all, they are still best used in the daylight hours. On the other hand, it really is a fantastic way to read a book title using a tablet or I-pad with the brighter background, and the advantages are clear particularly in the Winter months.
