Mathematical literacy and basic competences in science and technology Technology Definition: –usage and knowledge of tools, machines, techniques, crafts or methods History: –Paleolithic (2.5 million-10,000 BC): use of stone tools, Fire, clothing, shelter –Neolithic through Classical Antiquity (10,000BC- 300AD): use of metal tools, energy, transport, invention of wheel –Medieval and modern history (300 AD  ): silk, horse collar, windmills, clocks, printing press, mining, agriculture, advancements in medicine- end up to things as we know them today

This project has been funded with support from the European Commission. Mathematical literacy and basic competences in science and technology Technology Advantages: –change in culture: Through out the centuries there were many technological advances, like the invention of the wheel; the creation of boats and vehicles using the wheel; the development of cookware; clothing; building homes, all having an impact in our culture. For instance, people used to stay on caves. Eventually, people were leaving on wooden houses, now each era has its own architectural style, either with marbles, voltaic etc. –change of culture: since people are now in a position to travel and communicate with others around the globe, they can educate themselves about other technological advances. Ideas and methods are therefore transmitted and eventually, a change of culture occurs.

Can you think of more examples?

This project has been funded with support from the European Commission. Mathematical literacy and basic competences in science and technology Technology Disadvantages: –Weapons: technological advances brought an increase in warfare. –Pollution: for example, factories pollute the environment (industrial pollution), transportation, wastage, chemical compounds, –Decrease in jobs: machines now do the work Ethics are involved –waste incurred –Conservation of energy and resources, – and about employment. The aforementioned advantages and disadvantages have an impact in society, and this is why ethical questions should be raised.

This project has been funded with support from the European Commission. Mathematical literacy and basic competences in science and technology Types of Technologies Medical technologies –Medical technology is the use of a device or invention to extend the life of patients, relieve pain and reduce risk of disease. Examples of medical technology include medical and surgical procedures, medications, medical devices and diagnostic tests. It is difficult to think of modern medicine without medical technology. Agriculture biotechnologies –Biotechnologies use living orgasms to modify products, and in this case agriculture products. For example, farmers will need to ensure that natural resources are used more efficiently.

This project has been funded with support from the European Commission. Mathematical literacy and basic competences in science and technology Relationships Science and Technology: –Science “refers to a system of acquiring knowledge. This system uses observation and experimentation to describe and explain natural phenomena. The term science also refers to the organized body of knowledge people have gained using that system. Less formally, the word science often describes any systematic field of study or the knowledge gained from it.” ( – Technology is the innovation, modification and change of the natural environment. It extends our abilities to change the world: to cut, shape, or put together materials; to move things from one place to another; to reach farther with our hands, voices, and senses. (Benchmarks for Science Literacy, AAAS, 1993)

Mathematical literacy and basic competences in science and technology Science Vs Technology ScienceTechnology Ασχολείται με τα φυσικά φαινόμενα.Ασχολείται με το πώς οι άνθρωποι τροποποιούν ή ελέγχουν τον φυσικό κόσμο. Ασχολείται με το τι υπάρχει στον φυσικό κόσμο (π.χ.: Βιολογία, Χημεία, Φυσική, Αστρονομία, Γεωλογία κτλ.). Ασχολείται με το τι μπορεί ή θα επρεπε να σχεδιαστεί, να φτιαχτεί ή να αναπτυχθεί από τα υλικά και τις ουσίες που παρέχει ο φυσικός κόσμος, για την ικανοποίηση των ανθρώπινων αναγκών και επιθυμιών. Ασχολείται με τις διαδικασίες που χρησιμοποιούνται για την κατανόηση του φυσικού κόσμου μέσω έρευνας, εξερεύνησης και ανακάλυψηςIs concerned with processes and tries to understand the natural world by “inquiry”, “discovering what is”, “exploring” and using “the Scientific Method”. Is concerned with such processes, used to alter the natural world such as “Invention”, Innovation”, etc

This project has been funded with support from the European Commission. Mathematical literacy and basic competences in science and technology Technology and Society Issues which are raised/ points to think of: –Citizens need to understand: How technology effects: –cultural, social, economic, and political factors. –the environment. The role of society in the development and use of technology. The influence of technology on history. Perhaps knowledge on these issues will enable society to evolve through the centuries, decreasing ethical and environmental problems

This project has been funded with support from the European Commission. Mathematical literacy and basic competences in science and technology Technology and Culture Cultural needs drive and inspire technological change and innovation respectively –For instance, the art of warfare brought a cultural change and thus to the invention of guns Transmitting technologies to other cultures may lead to a change of those other cultures. However, different geographical needs and environments have different needs, adjusting technology adequately.
