I like to use learning inventories and multiple intelligence activities to gather knowledge of their background and their learning styles. I can then plan instruction based on that data. Some examples are allowing students to make connections to the topic during the introduction and throughout the lesson, creating charts during instruction that highlight the key information presented, and having students summarize the main ideas and concepts using our chart. Providing "brain breaks" throughout the day is important for young children and especially for the students with limited attention span. Small group instruction is also a very effective way of making sure that all students can access important content, and keeping groups flexible allows teachers to match students with different peers for different types of activities.
This was a difficult question, and I answered with well you never really know if they are just rumors but I would maybe ask the teacher to speak to me personally about it, and if anything were to get out of hand, I would like to bring the administration into the situation.
I would talk to the staff member, and outline some strategies they might use in discussing their concerns. I might offer some reasons for the staff member's behavior.
