Here are a few ideas to consider when trying something new adapted from Tips for Teachers.
Can I improve something I am already doing?
Before looking to make wholesale changes to your teaching, based on your reflections, identify practices you already do and look for ways to improve them. This should take less time and effort and give you a platform of success upon which to make further changes in the future. For example:
Instead of several worked examples that you have to whiz through, choose one or two that you have thought carefully about. Spend time going through them. Consider modelling them in silence first, and then using carefully considered self-explanation prompts/questions to give students a better opportunity to understand the process.
How will I know if the idea works?
How are you going to know if the idea has been a success or not? The more objective the measure, the better. For example:
If you are looking to boost your participation ratio by using tools like (Top Hat or PlayPosit), track the number of times you see responses from all students.
What will I have to stop doing?
This is the question that gets asked the least, and yet is so important. Trying something new may mean you have to no longer do something else. This plays out in two ways: A new idea in the classroom may mean you have less lesson time to do something else. Is that a sacrifice worth making? Planning a new idea may mean you have less planning time to work on something else. Is that a sacrifice worth making?
