For me, the most interesting hypothesis that we were introduced to in this lecture was The Affective Filter Hypothesis. This is the idea that emotional variables can have an effect and prevent someone from learning a language. These include motivation, self-confidence, and anxiety. The lower the affective filter, the more language the student will acquire. This shows that a child with low self-confidence may not pick up a language as easily as a child with high self-confidence. According to the ONS Child and Adolescent Mental Health Survey (2004), 2.2% or about 96,000 children have an anxiety disorder. This shows that most likely, teachers will be faced with the challenge of trying to teach a language to a child who cannot acquire it as easily as the other children in the class. However, Krashen claims[A3] that children do not have the same affective filter as adults but also experience differences related to the affective filters. An affective filter only accounts for individual variation in language acquisition, it cannot be applied to all children.As well as this, we also looked at the Count Us In – A Sense of Belonging (2009) which highlighted the importance of improving the learning of some pupils. As well as this, the document made me aware of the shift in patters of migration, especially since 2004. Due to easier access and cheaper travel, the number of immigrants coming to Scotland has increased dramatically. Many of those immigrating to Scotland bring with them young children who have to be put into the schooling system. This Count Us In document emphasises the importance of teachers in supporting newly-arrived children and ensuring that they can access the curriculum. As a trainee primary teacher, this is extremely important to me as children must be able to access the curriculum in order to learn and succeed.
