Hi, a warm welcome to the site. challenges include using the correct language
definition of objective and knowing what to write down, not embellishing on what you see and hear, remaining impartial and not including any judgements/judgemental ideas about why you think children are behaving in particular ways.
Objective observations ought to support your practice by providing snap shot information, evidence, facts or statements about what's happened during an observed time frame and the specific language that children have used on that occasion.
Using the observation as a reference you can begin to know your individual children. See how they communicate, with who and where. You may be asked to omit children's full, identifying names. As an example of this in practice you may begin to notice where challenge or difficulty exists for a child and as a professional be able to deploy yourself to places in the setting so that it's easier to minimise interference (eg. needing to rush over to prevent the escalation of conflict) and be close enough to help with negotiation.
Observations support children's leaning and development by providing a record regarding personal interests and friendship groups, this would enable activities to be planned that enrich and expand on the setting's layout and children's experiences.
If you can get hold of a copy of either
observation & planning handbook or
Kathie Brodie's observation, assessment & planning book - links are to amazon.co.uk they'll help with research for this. Maybe ask your setting if they'd fund one for the staff library? Try not to feel too overwhelmed xx
