To evaluate effectively you should refer to the original learning objective to see what you set out to achieve and then reflect on the outcome and whether or not this outcome was satisfactory and that the targets you set have been met.
In order to evaluate accurately you must be sure to make learning objectives very clear at the planning stage. This must be done in a way that ensures learners fully understand what the outcomes mean and the outcomes must be achievable for everyone in the group regardless of ability and within the time that you have available. The learning objective should be set out in a way which makes it easy for you to assess pupils against it.
A good knowledge of the success criteria is also important when evaluating learning as children may not necessarily achieve the learning objective despite fully involving themselves in the lesson and showing real enthusiasm. Where this is the case you should record how hard the child worked and take a look at the reasons they did not meet the objective and see how you can help them the next time. The resources you have used also play an important part in how successful an activity is so you should evaluate the resources you used and whether or not they were used correctly and decide if there were other things you could have used that may have been more relevant and beneficial to that particular task.
Continual assessment is important to monitor a Childs progress and while you should share the information with other teaching staff it is also important to share it with the child. This allows the child to share with you any concerns they have, things that they find difficult and things they enjoy which allows you to plan activities
