Uses of Radiocarbon Dating Climate science required the invention and mastery of many difficult techniques. These had pitfalls, which could lead to controversy. An example of the ingenious technical work and hard-fought debates underlying the main story is the use of radioactive carbon to assign dates to the distant past. The prodigious mobilization of science that produced nuclear weapons was so far-reaching that it revolutionized even the study of ancient climates. The radioactive isotope carbon is created in the upper atmosphere when cosmic-ray particles from outer space strike nitrogen atoms and transform them into radioactive carbon. Some of the carbon might find its way into living creatures. After a creature’s death the isotope would slowly decay away over millennia at a fixed rate. Thus the less of it that remained in an object, in proportion to normal carbon, the older the object was. By , Willard Libby and his group at the University of Chicago had worked out ways to measure this proportion precisely. Their exquisitely sensitive instrumentation was originally developed for studies in entirely different fields including nuclear physics, biomedicine, and detecting fallout from bomb tests.

Most primary schools today in England and Wales would claim to be following a maths mastery approach in their teaching of mathematics. However the way this mathematics teaching and learning approach is being delivered and the degree to which children are seen to have mastered maths in each school will vary immensely. When the new national curriculum was introduced in , Third Space completely revised our own programme of one to one lessons that we use in our maths interventions in order to align with the scheme of work that each school used.
The aim of this article and the accompanying free downloadable maths mastery toolkit is to empower leaders and teachers to really embrace the principles of maths mastery teaching, confident that they understand the reasons behind it, and how to follow a maths mastery approach. Maths mastery is a teaching and learning approach that aims for pupils to develop deep conceptual understanding of maths, rather than being able to memorise key procedures or resort to rote learning.
Mastery of a mathematical concept means a child can use their knowledge of the concept to solve unfamiliar word problems, and undertake complex reasoning, using the appropriate mathematical vocabulary. Maths mastery is a not a quick fix to maths learning but a journey that the teacher and pupils go on together, with regular diagnostic assessment to check the pupils understanding and direct instruction that teaches to any gaps.
Explaining how or why something happened became merely an afterthought. However, by not teaching children conceptually, we left them incapable of making the necessary links required to problem solve an increasing priority in the new Maths curriculum. More importantly, it denied children the opportunity to truly enjoy and engage with mathematics — as it became merely a memory test for many of them. With the new curriculum, this began to change. Increasingly children are required to reason, problem solve, and discuss methods.

The control of fire by early humans was a turning point in the technological evolution of human beings. Fire provided a source of warmth, protection from predators , a way to create more advanced hunting tools, and a method for cooking food. These cultural advances allowed human geographic dispersal, cultural innovations, and changes to diet and behavior. Additionally, creating fire allowed human activity to continue into the dark and colder hours of the evening. Claims for the earliest definitive evidence of control of fire by a member of Homo range from 1.
Use and control of fire was a gradual process, proceeding through more than one stage. The next stage involved interaction with burned landscapes and foraging in the wake of wildfires, as observed in various wild animals. The next step would be to make some use of residual hot spots that occur in the wake of wildfires. For example, foods found in the wake of wildfires tend to be either burned or undercooked. This might have provided incentives to place undercooked foods on a hotspot or to pull food out of the fire if it was in danger of getting burned.
This would require familiarity with fire and its behavior. An early step in the control of fire would have been transporting it from burned to unburned areas and lighting them on fire, providing advantages in food acquisition. Building a hearth or other fire enclosure such as a circle of stones would have been a later development.

According to evolutionary psychology, individuals are motivated to engage in behaviors that maximize their genetic fitness. Like physical traits, these mutations in behavioral traits may help the organism reproduce; this in turn allows the mutations to be passed on to the next generation. In this way, individuals are motivated to engage in behaviors that maximize their genetic fitness. Evolutionary Psychology : Evolutionary psychology suggests that individuals are motivated to engage in behaviors that maximize their genetic fitness.
All animals, including humans, need to act in ways that will improve their reproductive success. According to evolutionary theory, those who are the most fit are the most likely to survive, and eventually the population evolves in such a way that their traits manifest themselves across the population. Over time, mutations accumulate and another genotype develops that causes infants to become uncomfortable and cry when their mothers leave them.
Naturally, the crying infant who signals distress will be more protected from the elements and other predatory environmental forces than the unattached infant. Thus, a new behavior develops by means of natural selection. This illustrates the basic idea behind evolutionary psychology in human development: the innate behaviors of very young children are pre-programmed in their genotypes and can be understood by studying the environmental forces that surrounded our ancestors.
William James — was an important contributor to early research into motivation, and he is often referred to as the father of psychology in the United States. James theorized that behavior was driven by a number of survival instincts. From a biological perspective, an instinct is a species-specific pattern of behavior that is not learned. There was, however, considerable controversy between James and his contemporaries over the exact definition of instinct.

Communicative Language Teaching. The origins of Communicative Language Teaching CLT are to be found in the changes in the British language teaching tradition dating from the late s. Until then, Situational Language represented the major British approach to teaching English as a foreign language. In Situational Language Teaching, language was taught by practicing basic structures in meaningful situation-based activities.
British applied linguists emphasized another fundamental dimension of language that was inadequately addressed in current approaches to language teaching at that time – the functional and communicative potential of language. They saw the need to focus in language teaching on communicative proficiency rather than on mere mastery of structures. Another impetus for different approaches to foreign language teaching came from changing educational realities in Europe.
With the increasing interdependence of European countries came the need for greater efforts to teach adults the major languages of the European Common Market and the Council of Europe, a regional organization for cultural and educational cooperation. Education was one of the Council of Europe’s major areas of activity. The need to articulate and develop alternative methods of language teaching was considered a high priority. In a group of experts began to investigate the possibility of developing language courses on a unit-credit system, a system in which learning tasks are broken down into “portions or units, each of which corresponds to a component of a learner’s needs and is systematically related to all the other portions” van Ek and Alexander 6.
