End of the lesson

38-40 min

At the end of the lesson, learners reflect on their learning:

✓            What has been learned

✓            What remained unclear

✓            What needs more attention

Reflection Thermometer:

                          36,6⁰С  interesting, useful

                          38⁰С is not interesting, hard

                          34⁰С useless, priceless

Assessment – how are you planning to check learners’ learning?

Differentiation - how do you plan to provide learners with  Evaluation - how do you plan to check learners for more support?

Evaluation - how do you plan to check learners for the level of learning acquisition?

Health and safety rules

Differentiation can be expressed by choosing tasks, an expected outcome from a specific learner, giving individual support to a learner, selecting teaching materials and resources taking into account individual abilities of learners (Theory of Multiple Intelligences by Gardner). 

Differentiation can be used at any stage of the lesson considering efficient use of time

Use this section to record the methods you will use to assess what learners have learned during the lesson.

Health promoting techniques.

Breaks and physical activities used.

Safety Rules items that are applicable in this lesson.  

Reflection

Were the lesson objectives/learning objectives realistic?  

Did all learners achieve the LO?

If not, why?

Did my planned differentiation work well?  

Did I stick to timings?  

What and why were the deviations from the lesson plan?

Use this section to think about the lesson.  Answer the most important questions about the lesson in the left column. 

Overall evaluation

Write down two aspects of the lesson that went well (think about teaching and learning).
