Summative Test in Mathematics, Exams of Physical education

Physical education

This paper will tell about how much did the students learn from the previous lessons discussed by the teacher. The teacher could check the level of understanding of the students and he or she will be able to reflect on his or her teaching methodology, structure and strategies. For the students, they could take a deeper understanding of what they learned and discussed in the previous topics. They could assess theirselves on how much learning they have acquired in the previous lessons that their teacher have taught. They could also review their lessons to be able to signify that the acquired knowledge that they have in the previous topics are being understood. They could also apply the learned topic in their own experiences for them to become responsible individuals. The topic was done on March 04, 2025 and discussed for one week. The students are high school students. The teacher is a Mathematics major and she really assessed the students way of thinking first before making this test.
