Use of Class Time

Time
Phase of Lesson
Instructional Strategy
The teacher is…
The students are…
11:20-11:25
Warmup
Group Work
Taking attendance and discussing upcoming events [at front]
Working in groups to solve a problem on the board
11:25-11:33
Warmup
Lecture
Explaining the method and solution to the warmup problem [at front]
Comparing their solution to the teacher’s and asking questions about any difference they might have.
11:33-11:36
Transition
Lecture
Explaining how we don’t have the right tools to accurately solve the warmup problem as a lead in to the lesson [front]. Then collects the warmup problems and hands out a worksheet[walking through class]
Listening, then handing in their warmup problems
11:36-11:39
Initiation
Lecture
Filling in the initial parts of the worksheet on the document camera [front]
Copying down the teacher’s notes onto their own worksheets
11:39-11:41
Development
Individual Exploration
Asking the students to answer the first few questions from the worksheet [front]
Working through their worksheets individually
11:41-11:44

Talking to each other and waiting at the door for the bell to ring

1. Describe how the teacher’s use of time and the instructional strategies facilitated or hindered the accomplishment of the main objectives of the lesson. 

This class took place on the same day as the school carnival, thus, classes were shortened and students were likely to be distracted. At the same time, My CT really wanted to cover the basics of trigonometry before the end of the week. This meant he had to be very specific about his time and classroom management to make sure the students understood this important concept. He told me afterwards that while he usually likes to give the students time to explore and figure out concepts in their own groups, the combination of the time issue, plus the fact that SOH-CAH-TOA is more of an axiomatic aspect of mathematics than something that can be derived, made a more traditional lecture focused class more effective for this day. 

I think he was very successful in this regard, the change in teaching style sent a message to the students that SOH-CAH-TOA was something that just needed to be memorized instead of figured out. Afterwards I heard them discussing how the acronym worked when usually I hear very little math based discussion at the end of class. 

2. Based on your observation and interview, how are you thinking about the ways in which you hope to use class time in order to achieve your goals?

I picked this day to do my time management discussion because I knew time management would be particularly important. It showed me that often the teacher has to consider many factors beyond just how best students usually learn. There can often be special circumstances that will take precedence. If I was a new teacher who hadn't considered this, I might try to just teach a regular lesson on the school carnival day. If this meant students were suppose to discover a concept by working in groups they very well may have spent their group time talking about the carnival (This isn't to say that students will be on task the whole time while in groups, but this day there was a particularly distracting factor). Then the shortened class time would mean that even if I realized this was happening, I wouldn't have time to make the necessary correction. In the end, the whole day would have been wasted and I would've been better off just showing a movie and at least catching up on my grading during that time. 

I believe that exploration and discovery is the best way to learn mathematics. However, this is not always viable and I have to keep in mind situations where it isn't. I need to keep the state of mind of the students when planning the lesson to be able to use my time effectively.

  1. When you say students are discussing, working in groups to solve a problem, or listening what does this look like? Describe what you see and how you know students are doing these things?

    I also notice that in your last row you describe the last two minutes of class when students are waiting at the door as “closure.” I wonder if this was truly the closure of the lesson. What would a lesson closure look like? Maybe this is what you describe as summary. Sometimes these two terms are used in the same way… Does the summary/closure need to be the teacher reviewing or could the students be involved more actively in this?

    I think that you make an important point about the many things that a teacher need to keep in mind including having to choose the best structure/strategies to fit your goals and the school activities. I think this is an important thing to keep in mind. I would suggest that for some students it might be that working in groups and discovery is an “easier” way for them to pay attention and get less distracted. Once again, it might be that it is just more visible when trying to do something less-teacher directed that students get distracted.

    I do wonder whether right triangle trig needs to be seen as SOH-CAH-TOA and something that merely needs to be memorized. Can we develop these in different ways… particularly tangent? How might one develop the concept of tangent without SOH-CAH-TOA? How might this pneumonic device obscure the meaning?
