What constitutes “good teaching” is not a well defined term. My evidence for this claim is that so many organizations appear to use very different exemplars of good teaching when sharing their work.
For example, this is considered good teaching by the Whole Brain Teaching institute.
The Program for Complex Instruction would likely define this as good teaching.
Seymour Papert, and other constructivists would likely define this as good teaching.
People who follow John Sweller‘s (and company) work on Cognitive Load Theory might offer this as an example of good teaching.
People who believe that the future of education lies in personalized education might offer this example as good teaching.
All of these methods of teaching are very different from each other. Would people who use these methods agree on what good teaching looks like? There would likely be some overlap, but if you took a representative of each of these teaching methods and asked them to observe a classroom (which as far as I know has never been done), I would be willing to bet that it would be very unlikely that they would agree as to whether or not the teaching they observed was “good teaching”.
A better measure of effectiveness is to look at the goals of the teaching, and the impact the teaching has on the learners in terms of meeting these goals. If you have x goal for your students, how much impact does your teaching have on your students? “Good teaching” would be therefore defined as teaching that has a greater impact on achieving a specific goal, and consequently, we are not able to define “good teaching” without knowing the goals. In the examples above, it is hopefully clear the goals of each the users of each teaching method are different, and consequently each of these could be considered good teaching, within the set of goals defined.
What goals do you have for your students? Are your goals the right goals for your students? Who has defined the goals for your students? How do you know if your students are closer to achieving your goals than when you started teaching them?
If you can answer these questions, you will be a lot closer to knowing what kind of teaching you should be using, and whether or not it is effective.
This is the presentation proposal I submitted last Thursday to the NCTM conference committee. Would you attend this workshop?
Description:
Effective mathematics teaching is more than just teaching procedures; students must have opportunities to grapple with rich mathematics. In this workshop we will collaboratively investigate using rich math tasks to explore students’ use of the Common Core Standards for Mathematical Practice as part of formative assessment for learning.
Objective:
Participants will walk away from this workshop with a source of rich mathematics tasks they can use in their classroom, and a flexible and useful protocol they can use to interpret student thinking about these tasks as part of formative assessment practices. Participants will also explore the power of teachers collaborating together to make evidence based decisions and improve their own practice.
Focus on Math:
The participants in this session will be given appropriate rich mathematical tasks and samples of student work, all along the continuum of algebraic reasoning from grade 9 to grade 12. Participants will not only be able to use these tasks in their own classrooms, they will be able to apply the protocol for looking at student work for their own students’ work, and build their school teams’ capacity for collaboration at the same time.
I’m not an expert on standards by any means, but I know that the standards in British Columbia (where I was trained to teach) were coherent and made sense. You could follow the threads through the years and understand why they had been designed that way. I know that the Common Core content standards in Math have the same level of coherence.
I don’t know if they are always appropriate, or how one even defines appropriate given the strong relationship between what set of standards students learn under, and what they are therefore capable of learning in later years. I know that recent research suggests that young kids are capable of learning higher level math than what is currently expected, with many or even most kindergarten classrooms practicing skills with students almost all of whom have those skills. I believe in play based early years teaching, but this doesn’t preclude teachers from focusing on problem solving and pattern finding and continuing to develop students’ number sense.
What I do know is that the Common Core Standards for Mathematical Practice (SMP) are not pedagogy-neutral.
These non-content standards require students to be able to make sense of problems and persevere in solving them. This requires teachers to offer opportunities for students to problem solve (this is how some people define “doing mathematics”).
Students have to be able to construct viable arguments and critique the reasoning of others. While this could be done entirely through paper and pencil means, it is far easier to teach students to do this by regularly engaging them in dialogue and giving them opportunities to discuss mathematics together.
Students have to be able to model with mathematics, which again means that they have to be given opportunities to do mathematical modelling. The type of mathematical modelling described in the standards requires students to be able to make sense of problems resulting from everyday life, which means that teachers should be using examples of problems that result from the cultural contexts students live in (it’s not everyday life if it’s someone else’s life).
These are just three of the eight SMP, and the other five SMP also have pedogical signficance attached to them as well. The SMP require that some teachers teach differently than they do, and that therefore hopefully more students will get opportunities to grapple with mathematical ideas.
What I think we need to be careful to recognize is;
tl;dr: Strategic inquiry is a lesson study structure.
One of my roles in my current job is to help facilitate team meetings for two schools. In these team meetings, our objective is to collaboratively study our individual impact on student learning, and work together to design instructional strategies for improving the learning outcomes of students.
This means we collaboratively:
Teachers definitely need to collaborate in this process. The most important reason to collaborate with other teachers when studying the impact of your own teaching; other teachers can offer insight and feedback that you cannot see yourself. Also, when you first start looking carefully at the impact of your teaching, it can also be disheartening sometimes to see how little impact you sometimes and having some colleagues to reflect on this and offer support is invaluable.
There is evidence to suggest that teachers improve faster when they work together to plan and reflect on their teaching. Two central tenets of John Hattie’s book, Visible Learning for Teachers (2012), are that teachers should know their impact, and work together to improve each other’s teaching. A highly effective model, Hattie suggests, is for teams of teachers to norm around what it means to be successful in their subject area, look at sources of student data, and collaboratively create instructional plans to attend to trends in that student data. In Ilana Horn’s summary of her research into professional learning of math teachers, she suggests that teachers learn most about teaching when their conversations are centred around teaching, students, and mathematics.
I have a proposal. I would like to form and facilitate an inquiry group of 3 or 4 other people from the online mathematics community. We would start the inquiry process for next September.
Here’s what would make your participation ideal:
Here are two other ideas to make our work even MORE ideal:
Benefits:
If you are interested in participating, fill out this form here: http://wees.it/inquiry.
First, give an exit slip to your students based on a critical math concept for which you want to check for understanding.
After class, sort the exit slips into piles based on the method students chose to use (whether they used it perfectly or not). Choose two examples from the student work that highlight one or two probable misconceptions students still have on the chosen critical math concept.
Remove identifying information from the student work, photograph it (or use a document camera) and show it the next day in your class. Ask students a question about the work that requires them to think about the work. “Which one of these two examples is correct?” is not a very good question because it can be answered by guessing. “Why do I really want these two students to talk to each other about their solution?” is a better question because if students answer it, they will have to think about the concept a bit differently.
Ask students to think about their own answer, write it down (if necessary), then turn and talk and share their work with a partner while you circulate and listen in on student discussions. Select 1 – 3 students to share their thinking with the whole class.
Repeat this every day.
The objective of my presentation at NCTM in New Orleans was to introduce participants to social media, which was made difficult because participants did not have Internet access. As it turns out, this ended up forcing me into a couple of activities which were pivotal experiences for participants.
Here are my slides from my presentation.
Instead of trying to bring my participants to the Internet, I brought the Internet (or at least a portion of it) to my participants, and in doing so, provided them with concrete examples of how people use social media to interact.
I started my presentation by sharing some of the stories I have from my use of it, and who I have been able to interact with and how this has enriched my professional learning. If you use social media as a professional tool, then you have some of these stories too.
Next, I gave them an experience of what it might be like to participate in a live Twitter session. Participants were given a question, 30 seconds to find new group members, and 140 seconds (suggested by Dvora) to discuss the question in their small groups. This highlights that Twitter conversations are often with people you don’t know very well, and can be brief and short interactions.
I then asked participants to describe the attributes of our face to face conversations, and then speculate as to how these might transfer to an online conversation. I then highlighted for participants some of the features of these kinds of conversations. In particular, the conversations parallel conversations you would have with people face to face, but that conversations online can take place between participants who are separated by vast geographic (and cultural) differences.
Participants went around the room and read one or two of the four blog posts I had printed and put up on the wall, and put sticky notes up to comment on the blog posts. We then debriefed the experience with the main observation being that blogging is a lot like reading and responding to a letter from the editor.
Finally I wrapped up by talking about some of the specific projects that have been created through collaboration with other people in the online mathematics education community, and how our participation online has resulted in resources of real value in our teaching.
In the final questions at the end, one participant astutely observed that it would be easy to find a “how-to” guide online, but that he felt my “why-to” session was more helpful. There’s no reason to tell people how to do a bunch of technical details if they don’t see a reason to do them.
