A physical education teacher has included an objective for student heart rates to reach a target range when they play a sport. The teacher discovers the majority of students did not reach that target. What is the best example of the teacher's response to this discovery that uses reflection to inform instruction?
1) The teacher adjusts the target heart rate range to be more attainable for the students.
2) The teacher ignores the students' failure to reach the target heart rate range.
3) The teacher cancels the objective and removes it from the curriculum.
4) The teacher blames the students for not trying hard enough.
