During this observation, I observed an online advanced grammar class. During this class the teacher reviewed present time verb tenses and introduced past time verb tenses. The beginning of the class went very well, however after the warm-up activity the teacher experienced a great deal of technical difficulties. The technical difficulties I observed highlighted two important lessons, that in the future I will keep in mind when planning and giving lessons. The first lesson I learnt through observing this class is that it is important to test new technology outside of class time to ensure that it will work. Due to the issues with technology, there was a period of about fifteen minutes in which students were not engaged in an activity. Despite the technical difficulties, I believe that the use of new technology and new activities demonstrates flexibility and adaptability on the part of the teacher. The teacher was willing to go beyond their comfort zone to better serve the students, which I think is a sign of a good teacher. The second lesson I learnt through observing this class is that not everything always goes as planned in the classroom and that it is important to remain calm when things do go wrong. Even during the period in which the teacher was unable to get the technology to work, she remained calm and had open dialogue with the students about the challenges she was experiencing. Observing this lesson, also allowed me to gain an understanding of the types of activities and material that is taught in an advanced grammar class.
