Five Good Reasons To Go Into Teaching

When I ask students I am surprised at how thoroughly students would be able to explain to me why teaching was not an option for them. It is not a decision that they have made lightly. They know the projections of pay, the direction of legislation and the costs that they would need to input. But there are also good reasons to go into teaching that they are not aware of. 

Unsettled research

The access teachers have had to cognitive science research and how learning works has been limited until recently. As we continue to improve our understanding of learning, the research connecting that cognitive research to teaching is stuck. Teaching must be complex enough to cause permanent change in the brain structure. Teaching must also be simple enough to not overwhelm the short term memory capacity. Many teachers and researchers embrace one of those ideals but not both. Thus a large conflict prevents us from pushing education research ahead. That will change in the near future and you would be able to be a part of that. Other fields have research that is so advanced and settled. Our knowledge of medicine, economics, philosophy, science and mathematics are advanced to a point where the specifics are so advanced that they contribute little. But education has so much room for growth and improvement. Soon our abilities to teach and learn those other fields will be limited to how quickly we can educate people to the point where they can understand the new research needs of them. 

Autonomy 

The most important factors in a career is not money. Study after study shows that having autonomy in your job is one of the biggest keys to being happy and feeling impactful. Next week I will be teaching about chemical reactions. The number of approaches and methods that I could use to do that is unlimited. I have so much control over what I choose to do. I can experiment and try something new. I can take ideas from other teachers. I can do what I did last time with minor changes. On Tuesday I will be doing a new lesson that I got the idea from a book that I am currently reading. At any given moment when inspiration hits I am able to put that idea into action. What other job has that at this level? 

Ability to learn with an audience to keep you accountable

There was a reading teacher next door to me who would put up posters where she would put the book covers of books she read. I started to do so and quickly found myself reading more and more books. I am currently reading my 54th book this year and I love it. But being a teacher is a huge reason why I love it. I get to share what I read and learn with my students. If I read an interesting book about rust, I am able to use that in a lesson with my class. Everything that I learn about I have an audience to reinforce my own learning as I share it. I’m not convinced that if I went into work and was restricted from sharing my learning that it would not carry the same meaning to me. Whether the topic is history, chemistry, geography, environmental science, cognition or something else; I can always connect those topics to my teaching. It enhances my teaching. 

The most difficult job

Teaching is the most difficult job that exists. The sheer volume of decisions that teachers make during a lesson is enormous. No matter how well you teach something there is always a way to improve your lesson because there are so many different options you have. Having the ability to deal with managing children in a way that optimizes their learning involves decisions about their cognition, their prior knowledge, their emotional health, the physical arrangement of the room and the lesson medium. Because of the overwhelming number of students (150-250) you must have plans for an incredible number of disruptions and adjustments to make. You have to introduce a new idea in a way that maximizes learning, provide practice that maximizes learning and give assessments that measure the learning that took place. All of that must be done to a large group of students with wildly different experiences and prior knowledge. Whether the goal is to maximize learning or to maximize homogeneity in knowledge is inconsistent depending on the objective, course and content piece. Behind all of these pieces is the content itself. I must understand all of the chemistry I am presenting which includes all of the chemistry that students perceive. I must understand and be prepared to respond to every conception that a student brings to the classroom along with what evidence and theory can advance those conceptions to better models. It is an unending journey towards a perfection that doesn’t exist even in theory. No other profession comes close to the combination of skills needed to maximize success. And that challenge is welcome. Teachers seek challenge. They want to be pushed to the limits of human ability. 

Online networks

When I was in high school teachers were isolated. They would seek community in lounges, but the atmosphere was potentially toxic. With social media teachers are able to connect with other teachers. We have access to the best of the best and can use each other to further our own abilities. The sharing and cooperation that results from social media has opened new doors to teachers from mentorship opportunities, to highlighting creativity, to challenging our own conceptions and ideas about teaching. These networks incentivize teachers to push beyond the typical boundaries of teaching that have existed in the past. Teachers can share improved models, dual coding and concrete examples for content. Teachers can share research, new pedagogy and more advanced curriculum. Teachers can learn from others about organization, technology, and creativity in lessons.

Daily student recaps

On a Saturday in late fall we held a follow up to our modeling workshop. One of the participants brought a colleague along with her. During one of our discussions she mentioned that she had been having students do a daily recap of the previous lesson. I thought the idea was brilliant and so I started having my IB chemistry HL class do it. I recently expanded the recaps to my chemistry classes. There are multiple benefits to doing this and I wanted to put them together and encourage teachers to try using this tool in your own classes.

1.  Students listen differently to their peers.

When I talk, the students trust me to say “correct” things about what we are learning. When a student is explaining that trust is not there. This causes students to listen differently with a more critical approach. If a student says anything that is slightly wrong or even if the letters they write are slightly misshapen they notice immediately. This type of critical listening is very valuable for student learning. They’re connecting topics and ideas and evaluating whether they fit or don’t. They should do this when I speak. Pointing out to them this discrepancy can be helpful for pushing their learning to a higher level.

2. What I think students know and what they actually know are frequently different.

Being able to see what a student took from your lesson is helpful. Sometimes teachers get wrapped up in the world of “But I told them once, they should understand it!” Spending time listening to students every hour to start things off builds a much better perspective of what they are learning instead of what you are teaching.

3. More student voice

At the start of this year I was nervous to call on quiet students during discussion. In the past students had given feedback that they would participate but that talking in front of everyone terrified them. It was a mistake to listen to that feedback. It created an unhealthy class dynamic where students sought out correct answers instead of focusing on what they currently understood. It pushed the idea that there are smart chemistry students and dumb ones. It was also racist and sexist in that some races and gender combinations were heard from more than others.

However, this is a concern for students and it needs to be handled well to be successful. When students say “I don’t know” during discussion, you’ll want to emphasize that the solution to not knowing something begins by starting with what you do know and building connections to those ideas. Frequently teachers undermine this by making statements about “being happy about mistakes” or “mistakes are opportunities to learn”. Instead it’s important to show students how to cycle through learning something new by seeking out a starting point of what a student does know and how to evaluate possible explanations, logic and evidence to build towards the new learning objective.

It is important not just to say this, but to keep a healthy approach as students do the recaps. Many are nervous but I see a lot of that disappear as I point out the good points of their recaps. As they realize the intentions of finding out what they know they produce more honest recaps. I would also like to say that I am frequently surprised at students that I would expect to struggle with a recap because they are quiet. These students are perfectly capable of doing an excellent recap and hearing from them improves their inclusion in the classroom.

4. Spaced practice

Spaced practice is the opposite of cramming. In cramming a set of ideas is repeated until familiarity sets in. In spaced practice the learning is split up so that forgetting occurs between the intervals of learning. The research strongly supports spacing practice. By allowing students to forget and then re-learn the material the impact on the brain is substantial. Doing a daily recap allows students to forget part of the material and then relearn it the next day. This leads to less forgetting and also better understanding.

5. Reflection

Students know that the next lesson will involve a randomly selected student giving a recap. When two or three minutes are left in a lesson the students can then reflect on what they learned and what they would present if they were to be selected the next day. This can help them evaluate and organize the learning.

This is a new technique to me but the value is already immense. I have thoughts on how to modify the technique such as having two students selected. One gives the recap and the other supplements additional ideas. The time varies because most students will talk for 5-6 minutes and not realize they had talked so much. Some teachers might elect to tell students the day before who will speak (which could be an issue if there is an absence). I roll dice to determine who will speak and they get no prep time to pull things together. Currently students can bring notes with them but they are discouraged from using them and not allowed to just write what their notes say. If they get stuck they are encouraged to ask questions to other students.
