Reflection: micro teaching of Infinite Geometric series







Our micro-teaching lesson did not go as well as I thought it would and I want to thank everyone for those very constructive feedbacks with great suggestions. First, I do agree that we should have a better hook, and using the real life application, which we used as our ending, could have been a better introduction. Another suggestion was to have a prop, and I think having a basketball and showing the bounce could also be a better introduction. We asked a few questions on the geometric sequence in the beginning, and I thought checking students’ prior knowledge could be done better or in another way since most people did not feel like their prior knowledge was assessed. Our intention for the four questions as an introduction was to use the geometric series formula as reminder and checking students’ prior knowledge from last class, and letting students find the infinite sum, which they are seeing for the first time, as an exploration and inquiry by using calculator, the formula or any other method. Then, we built up upon the geometric series formula and used that to generate the formula for infinite geometric series and talked about restrictions. We were planning to talk about divergence and convergence before generating the formula, however, because a student asked a question, therefore we switched the order from the plan. The first parts were also taking longer than what we expected so we did not follow our lesson plan on having the 3 groups and have students come up to the board to write the solutions. Instead, we only had time to talk about one question. Therefore, our participatory activity was not as engaging, collaborative and involving team work as the 3-group activity that we wanted to do. Lastly, I feel like the time management in all parts could have been better.
