Microteaching Lesson 2: Reflection

I enjoyed having this microteaching lesson as it gave us an introduction to teaching math in front of a class. I think our presentation went fairly well. It was structured, organized and it flowed well together. The class provided us with feedback on how our activity was fun and an engaging way to practice multiplying fractions. One thing, I would like to work on was including the whiteboard more during our lecture portion of the lesson. I also noticed that not many people wanted to come up to the board during our activity. I should have encouraged students more and made them feel comfortable coming up to the board. I could have done this by providing the group with some paper to work on the problem in groups or individually. Then start inviting people to share their solutions on the board. I have also noticed a few of the reflection sheets suggested projecting our voices louder as it was hard to hear. For the next lesson, I would like to work on and improve the projection and clarity of my voice. One great idea that was given in the peer assessment was to use concept  questions to check understanding rather than asking students if they understood the topic. I think this is a great idea and something I would like to use in the future.

Campbell Soup Problem

 Campbell Soup Problem


Solution:

  • I first found Campbell Soup cans have a height of 4.25 in and a diameter of 3.25 in (Flynn, 2020). In cm, this is 10.80 cm in height and 8.23 cm in diameter 


  • Then I found the average length of a bike which is 175 cm (Ellis, 2021)

  • I then estimated that the bike would fit approximately 3 times across the length of the large soup can. So the height of the large soup can is 175 cm*3= 525 cm


  • To find the diameter of the large soup can, I use the size of a normal-sized soup can and scale factors: 

Scale factor = Height of large can/Height of small can = 525 cm/10.80 cm= 48.61

  • To find the diameter of the large can, multiply the scale factor by the diameter of the small can: 48.61*8.23 cm = 400.07 cm


  • So dimensions of the large can/tank have a height of 525 cm and a diameter of 400.07cm


  • The volume of the large soup can: 

V=pi*r^2*h = (400.07/2)^2(525) = 65,996,538 cm^3


  • I then found the volume of water to put out a house fire is 20,000 gallons (Kiser Construction, 2021)

  • 20,000 gallons * 3785.41 cm31 gallon = 75,708,236 cm^3

  • Since the volume of the large soup can is 65,996,538 cm^3 so it's not enough to put out a house fire


Extension: 

One way I can extend this problem is by having students solve the problem:

How many average-sized water bottles would be needed to hold the same volume of water as the fire department soup tank?

Eisner Article Response

This article touches on this idea of “reward junkies”. I found this idea interesting as schools often use rewards such as grades, bonus marks, extra playtime during lunch and recess to motivate students into doing school work. Although this may work, there is the possibility that without rewards students wouldn’t have the desire to finish their tasks. Also over time, the rewards may lose their powers as they may not provide enough motivation. I think that the use of extrinsic motivation in the classroom isn’t the best way to engage students in learning. I would prefer to have students learn with the use of intrinsic motivations. This is when students want to learn about the subject or content because they are truly interested and curious about it. This can be difficult to foster in a class as students won’t be interested in everything a teacher has to teach. One way to accomplish this is to foster students' curiosity, provide them time for questions, and allowing them to follow through on those inquiries. Another point the article makes is the biases schools form towards Art subjects. It’s remarkable how schools have made the subject, Art, seem like a break from doing “actual work”. I think it’s crucial to have Arts in the curriculum as it allows the expression of individuality, creativity, and innovation. Arts education shouldn’t be pushed aside but rather used to build on skills that can’t be gained in courses such as Math, English, Science and Social Studies. This stigma can translate into students beyond high school. For example, students may feel as if they can’t pursue an Arts degree as it won’t provide job prospects and they may settle for something they’re not interested in. I think it’s important to have students realize that they should pursue and focus on their interests. 

A curriculum is a tool and outline used by teachers to teach students content. It involves two processes which are described as intellectual processes and content in this article. The intellectual process involves the development of cognitive development such as working on behaviors, attitudes, and emotions. Whereas, the content is the explicit knowledge that is taught to students and the information they are expected to know. Eisner also discusses the importance of what schools don’t teach. There are some aspects where students learn things just due to the organization and structure of schools. For example, the use of having required versus elective courses and the hidden messages this portrays. It can represent this ideology that taking a Math course is more important or superior than taking an Arts course. The B.C. curriculum has a few big ideas for each subject. It is then broken down into two streams which are the curricular competencies and the content. This is similar to Eisner’s thoughts about the curriculum. Eisner emphasized the need for schools to provide students the opportunity to imagine, invent and innovate. Through the B.C. curriculum, this is possible because the core competencies focus on inquiry where skills such as reasoning, analyzing, interpreting, communicating, and collaborating are given importance.

Battleground Schools: Response

The Battleground Schools article reveals some key aspects of mathematics education. While reading this article, one thing that intrigued me was the idea of “programming the environment”. I think the best way to learn math is by having students use inquiry and providing them with hands-on material rather than having students sit and listen to the teacher lecture. I was taught math by just having the teacher talk and I would zone out about halfway through the lesson. I was never really engaged with my learning so I think it’s very important to facilitate a class where there is that use of inquiry. Another thing that made me stop while reading was the problems parents faced when helping their children with the new curriculum. I can resonate with this as my parents learned different math techniques which made it difficult for them to help me with my homework. I also found the tables showing the opposing arguments for teaching math interesting. I liked how I could compare the conservative vs progressive for each area of interest. I was able to see in which areas I show more conservative and other areas where I was more progressive. 

Micro-teaching Reflection

 








I learned a lot from microteaching my lesson on card tricks. I learned that I was a bit nervous to present and that is something I should work on. I also forgot to follow some things on my lesson plan so for next time, I should double-check if I miss anything. Something I could improve on was the timing and pacing of the lesson. I didn’t time the tricks properly so not everyone in the group had enough time to try out the card tricks. I also thought the organization wasn’t the strongest. For next time, I would bring in a sheet with rules and I would also have a short wrap-up at the end. I thought the explanation of the card trick went great as the students that tried the trick were able to complete the task. Overall, I enjoyed teaching my lesson. I also enjoyed learning about the aspects of my lesson and delivery I should improve on.

Teaching Perspective Inventory: Results and Reflection

 


These are the results of my TPI graph. I scored above average for nurturing and developing with scores 45 and 38 respectively. I also scored 35 and 31 for apprenticeship and transmission respectively which were close to the mean. I scored the lowest for social reform with a score of 29 and it was recessive for me. One of the results that surprised me was the score for transmission. I thought I would have a higher score for this as I think providing students with clear objectives and lectures is a key aspect to learning new content/material. One of the results that I wasn’t surprised by was the social reform score. I was expecting to score lower in this due to my teachable subjects. I thought it would be harder to provide students opportunities for social action/reform in a math or science class. However now reflecting on this, I could perhaps use Biology as a way to address social issues such as climate change, pollution, and species at risk. Some questions the TPI results raised for me was “what are some ways I can use social reform in a math or biology classroom?”,  “what are some underlying values I have and can learn from these results?” and “From these results, what are some assumptions that I have about teaching?”
