John Hattie
Hattie researched the influences on student learning and shows that teachers have a 30% influence on the student. This figure is placed second to the students’ themselves, and therefore Hattie explained that it was important to study the variations between expert and experienced (non-expert) teachers by listing a variety of dimension that affect learning outcomes. The studies show that there are three dimensions that separate expert from experienced teachers, these are listed below:
• Challenge – Expert teachers set challenging goals and have students engage in doing these type of challenging task more often than non-experts.
• Deep Representation – Expert teachers combine new subject matter content knowledge with students existing knowledge, can relate current lesson content to other subjects in the curriculum and adapt lessons to student needs and goals.
• Monitoring and Feedback – Expert teachers anticipate and prevent disturbances from occurring whereas non-experts tend to correct already existing disturbances. Experts have more anticipation, which allows them to determine when students lose interest or are not understanding. They also filter information better and give greater feedback. Feedback is shown in the studies as the most powerful single moderator that enhances achievement (Hattie, 2003).
Critical Reflection
In Hattie’s graph of achievement variance the Teacher has a 30% influence on the student’s learning and peers between 5-10%. If Vygotsky arranged this graph it may look different. I feel the peer influence on the student would be closer to 20% as Vygotsky’s process of development are based around social interaction, which involves many peer to peer tasks. However if the figure for peer influence on student’s increases by 10% then what would happen to the rest of the graph. Would the Teacher decrease by 10%, unlikely but something else would change in Vygotsky’s mind.
