Pacing is still a challenge for me three years into teaching for me. Veteran teachers say that it comes with experience and time. The way a class is "paced" depends on a number of factors, largely out of the teacher's control. One factor to consider is student achievements of meeting the goals and objectives of the lesson. Another factor is the makeup of the class. Some classes read at a quicker pace and require less interpretation, while another class may struggle more with comprehension. This also has to be taken into consideration when planning and pacing lessons. If students are not "grasping" a concept, you cannot move on until some mastery is demonstrated. One mistake I have continued to make until this year is to take detailed notes of objectives, goals, and notes for each lesson. In the future when planning, pacing will be a lot easier because you noted key elements along the way.
