The purpose of the activities in the lesson was to get the students to figure out on their own what variables meant. Instead of the teacher just giving the students the information and diving into a worksheet, she wanted to build the students' understanding of the meaning of the word variables from the ground up. By having the students build the variable machine, they were able to use communication to develop different methods for figuring out how the variables worked. Some students realized that when they changed part of the process that it was not working. In order to figure out how to try something new, they had to figure out where they went wrong. This was the teacher's goal in the activity. By building on knowledge that they have to explore, the students gain a deeper understanding of the concept. From there, the students can develop their concept with a basis of understanding. Her purpose was to get children to understand that variables could represent a variety of numbers through exploration of methods. The students used the variable machine to gain understanding of how changing variables can alter results. By the end of her lesson, the children had communicated their methods for success and had gained an understanding of what the word and concept of variables meant. The teacher did an incredible job achieving her goal with her students in her classroom.
The three questions that I focused on while watching these videos were:
- What criteria do you use to determine whether or not to use a particular task with your class?
- The criteria that I would base whether or not to teach a particular task would be as follows. I believe that if I am going to teach a task, it needs to be interesting and keep the students' attention. If the lesson is not applicable to the students, then they do not really care whether or not they learn the material in the task. I also believe that a task needs to be aligned with standards and goals. If the task is authentic and can be applied to other situations in life, I believe it should be taught. Assessment is also important to look at when determining whether or not to use a task. If the task can be assessed in an informal or formal method then it is applicable to teach. The task needs to be educational and coherent. I also believe that if a task uses the standards of best practice then it should be taught in the classroom.
2. How do you tend to respond to students' answers to the questions you have posed, and how do you encourage students to ask questions themselves?
- I think that no matter what, students need to feel comfortable and safe in the classroom environment. From day one, students need to know that they are encouraged to ask questions and pose ideas. It is important to make students feel important by being enthusiastic when they ask a question during class. By doing this, students are then encouraged to ask questions themselves. I can remember sitting in class and being afraid to ask a question because my teacher would think it was 'stupid.' No classroom should give this impression to students. By posing questions, sometimes other students in the classroom are wondering the same thing! Feeling comfortable to ask questions by having a teacher that is receptive to questions is critical. Responding to students can happen in a number of different ways. I think that we as teachers need to listen well to what is being asked and then re-phrase the question being asked so that the rest of the class understands the question also. Encourage students to discuss with one-another when it is appropriate and be direct with questions that need to have direct responses. I think it is always important to empower our students by being positive to the answers that students give us to the questions we pose. By doing this, students will feel comfortable in the class. If a student has a completely wrong answer, maybe direct the student to seek help from another student to help explain how they got the answer. If there are shy students in the classroom, build their self-esteem! Ask them questions that you as the teacher know that they will know the answer to. By doing this, it makes them feel more comfortable and safe to answering questions and communicating in the classroom. Presenting a warm, safe environment where the teacher is encouraging and open to ideas and exploration presents many opportunities for students.
3. When during a lesson do you check to see what studetns have learned?
- At the beginning of the lesson there is an anticipatory set. The teacher then provides the students with information on how to do the task. We then model for the students how to do the task. I think at this point, we need to check to see if the students have questions before moving on to the next part of the lesson or task. If students do not have questions, pose higher level thinking questions to these students to get their minds thinking on higher levels. During guided practice is where I think it is important to see what students have learned. We can do this by walking around the classroom to see what and how they are doing. We can visually see what the students are learning and what they are having trouble with. In this particualr lesson, the teacher walked around and could see from converstations whether or not the students were gaining understanding or exploring to gain understanding. If students are not understanding at this point, we still need to provide remediation. The students will eventually learn---some just learn at a faster rate or on a higher level. I really liked how the teacher gave a table that already knew the answers a different higher level question to work on. She encouraged another table of struggling learners to continue to seek the answer. By allowing them more time on a subject that she felt was important, she allowed these students more opportunity for success. We can also assess what the students have learned during the assessment. Assessments need to be varied in order to be authentic. Testing students the same way every time does not show what the student has learned. Students show what they have learned better during different methods of assessment. As teachers, we need to provide them with the opportunities to show us what they have learned through these varied types of assessments as well.
I think that there are many overall uses for this video. Growing up I would have been thrown into variables not even having the slightest idea what the word even meant. I completed worksheets and more worksheets on variables without even knowing the basis of the concept. This teacher had an incredible method for getting the students to build their knowledge from the ground up! These students had an interactive, hands-on lesson that taught them to explore the idea of variables. Through communication and exploration the children worked with eachother to find out how these 'variables' worked. When the students did not understand, they had to move on by finding a reason for why it would not work the first time. From looking at the student work, it was interesting to see how the students crossed out things that worked and circled other parts that did work. One particular child's work starts out really sloppy and divergent, and then as you work down the paper it becomes more convergent and less sloppy. The work done by the child shows how his thinking starts out and how he/she builds on the wrong ideas that he/she has tested. This method teaches children what does not work has a reason attached to it as well. That reason is the basis for how to figure out what to try next. When the children started reasoning, they were able to find methods for how to make their variable machine generate larger numbers. The teacher's method of instruction showed me how math teaching needs to be more explorative for students. We need to help our students build on ideas and concepts instead of giving them the information and then throwing worksheets at them for 'understanding.' These videos gave me new insight to what I have to look forward to through teaching mathematics to my future students.
