Good morning, ladies and gentlemen. I’m Joanna White, a senior researcher and a teacher from Indiana Education Centre. It’s my great honor to give a lecture on education which, as we all know, can even change one’s whole life.
    I am speaking today on behalf of my research team which consists of two other primary teachers in addition to me. All of us are trained teachers with five years’ experience working in the children’s education area. We are exceptionally interested in investigating problems with reading habits amongst people in the primary level. We feel the primary period is important because this period falls specifically on our children. Our specific research firstly concerns TV’s influence on a child’s reading, and secondly if there is a link between children being good readers and having parental teaching, which is the main aspect we are going to focus on. Now I will just give you a little background on our proposal. Our motivation to investigate this question came out of a conversation with an 8-year-old child. He said he had certain difficulty in reading. However, he watched TV a lot because his parents were busy with their business. This is a rather disturbing situation. There are a total of 14 very poor readers in our school. In every single case we found they watched TV over 5 hours every day, in some cases up to 7 hours. Now this was in contrast to 10 average ability readers who watched an average of two and a quarter hours a day and who reported a maximum of one hour a day learning to read with mom and dad. What we’d like to do with our research is more investigations to expand the task, because we are dealing with young children’s education here and we will spend some time analyzing the correlation between the time of watching TV and reading ability.
    In addition, we are going to do further research and we have made three research proposals. Firstly, we propose to survey 150 children. We would like to do the survey in 8 schools. Secondly, we propose to interview 50 to 55 parents and we want it to be within the city limits. Thirdly, we are going to interview some teachers, which might give us additional information for our research, as we can do it at the same time when investigating the students.
    What I want to say in the end is that our research is very important. So when we need cooperation from you or your children, please don’t say no. Thank you.
