Case Study 1b - Cooper
Carol has asked you to support the babies and toddler’s room educators this week. She has requested that you complete an observation on Cooper, who is a 10-month-old toddler.
Carol wants to see how well you conduct an observation and is interested in how you manage to communicate in any observations made, using a strengths-based, non-judgemental, anti-biased approach, as this is a fundamental part of creating a supportive and respectful culture at Little Catalysts ELC.
