Why is the study important to human?

Lecture
Today, in our series of lectures on human language, we are going to be looking at the way in which children acquire language. The study of how people learn to speak has proved to be one of the most fascinating, important and complex branches of language study. So let’s look at these three features in turn. Firstly—why is it fascinating? This stems from the natural interest people take in the developing abilities of young children. People are fascinated by the way in which children learn, particularly their own children!
Secondly, it is important to study how we acquire our first language, because the study of child language can lead us to a greater understanding of language as a whole. The third point is that it’s a complex study because of the enormous difficulties that are encountered by researchers as soon as they attempt to explain language development, especially in the very young child.
In today’s lecture we will cover a number of topics. We will start by talking about research methods. There are a number of ways that researchers have investigated children’s language and these include the use of diaries, recordings and tests, and we’ll be looking at how  researchers make use of these various methods. We will then go on to examine the language learning process, starting with the development of speech in young infants during the first year of life. This is the time associated with the emergence of the skills of speech perception, in other words, an emergence of the child’s awareness of his or her own ability to speak. We will continue with our examination of the language learning process, this time by looking at language learning in the older child, that is in children under five. As they mature, it is possible to begin analysis in conventional linguistic terms, and so in our analysis we will look at phonological, grammatical and semantic development in preschool children.
In the second part of the talk I would like to review some educational approaches to the question of how linguistic skills can be developed. In other words, how can we assist the young child to learn language skills at school? Initially we will look at issues that arise in relation to spoken language; we will then look at reading and review a number of approaches that have been proposed in relation to the teaching of reading. Finally we will conclude today’s talk with an account of current thinking about the most neglected area of all, the child’s developing awareness of written language.
