Constructivism Case Study Analysis
In the article titled "A Constructivist Perspective on Teaching and Learning Mathematics", the author, Deborah Schifter, contrasts two mathematics lessons which she feels offers an understanding of the difference between a lesson based on constructivism and one based on the traditional didactic approach to learning.
In the traditional approach, the teacher has noticed that the students are very excited to find out that blue whales can grow as long as 100 feet so she decides to have the students measure this length in the hallway. Here's how she went about it:
I told the children exactly how we would go about measuring the whale's length. We would take the yardstick, which we hadn't explored, and we would put it down and keep track of where it ended and then place it there and keep counting till we reached where it ended and then place it there and keep counting till we reached 100 feet. (Schweitzer, 1996)
Although the children were quite impressed by the length of the whale, the teacher recounts that the lesson seemed unsatisfying, and wondered what the students had actually learned about measurement.
In the constructivist approach, the teacher had a measurement activity concerning Thanksgiving. She laid out a model of the Mayflower on the floor in the center of the room using masking tape. Then she prepared a scroll or edict for the students to read, telling them that the ship could not sail until they told the king how large the boat was. After the edict was read, she waited for the students to figure out how they could measure the ship and be on their way. Here's how she described what happened after the reading of the scroll:
"Well, what should we do? Who has an idea?" I asked. Thus our discussion of measurement began... or I thought it would begin. But there was a period of silence-a long period of silence.
What do young children know about measurement? Is there anything already present in their life experiences to which they could relate this problem? I watched as they looked from one to another, and I could see that they had no idea where to begin. Surely, I thought, there must be something they could use as a point of reference to expand on. Someone always has an idea. But the silence was long as the children looked again from one to another, to Zeb, and to me. (Hendry, 1996)
After some confusion about the word edict on the scroll (some students thought the boat was three feet long because the E in edict looked like a three) the following interaction occurred:
I felt we were back to square one again with more silence, until Tom raised his hand and said, "Mrs. Hendry, I know it can't be three feet because the nurse just measured me last week and said that I was four feet, and this boat is much bigger than me!"
From Tom's initial observation, our discussion on measurement was basically off the ground. Hands immediately went up. The children now realized that they knew a little about measurement, especially in relationship to their own size and how tall they were.
"Let's see how many times Tom can fit in the boat," someone suggested. Tom got down and up several times along the length of the boat: the children decided that the boat was four
"Toms" long.
"How can we tell that to the King, since he does not know Tom?" I asked. "Send Tom to the King," was their easy solution, while others protested that they wanted Tom to stay on the boat for the trip. I was really hoping that they would relate to the information Tom had already given us about his size. I thought someone might add four feet, four times, presenting us with a quick solution to the problem. But this was not the route they decided to take.
Mark raised his hand and suggested that we could measure the boat with our hands like they do with horses. His neighbor had a horse that was 15 hands. "Then we could tell the King how many 'hands' long the boat was." The children agreed that this might be a better idea.
"All right," I said. "Since it was Mark's idea, he can measure the length of the boat with his hands." Mark was also the biggest child in the class.
At first, Mark randomly placed his hands on the tape from one end to the other, but when he double-checked, he came out with a different answer. The children were puzzled for a while as to why this happened. It took several more tries and much discussion before they came to an important conclusion. The children decided that it was necessary for Mark to make sure that he began exactly at the beginning of the boat and did not leave any gaps in between his palms and his fingers as he placed them on the tape. Measuring this way, he discovered the boat was 36 hands long.
Great! We decided to tell the King this, but just to be sure, I suggested we have Sue, the smallest child in the class, measure the other side. She did and related to the class that her side was 44 hands long. Now there was confusion.
"Why are they different?" I asked. "Can we use hands to measure?" "No," the children decided, this would not work either, since everyone's hands were not the same size.
Al suggested using feet. We tried this, but once again, when someone else double-checked with their feet, we found two different measurements. The children at this time began to digress a little to compare each other's hands and feet to discover whose were the biggest and smallest.
Finally, our original discussion continued, while the children explored various concepts and ideas. Joan sat holding a ruler, but, for some reason, did not suggest using it. Perhaps, I thought, it might be that her experience with a ruler was limited, and she may not have been quite sure how to use it.
Our dilemma continued into the next day when the children assembled again to discuss the problem with some new insights. One child suggested that since Zeb knew the King, and everyone knew Zeb, that we should use his foot. 'Measure it out on a piece of paper and measure everything in 'Zeb's foot."' Using this form of measurement, the children related to the King that the boat was 24 "Zeb's foot" long and 9 "Zeb's foot" wide.
Curiosity began to get the best of them and the children continued to explore this form of measurement by deciding to measure each other, our classroom, their desks, and the rug using "Zeb's foot." I let them investigate this idea for the remainder of the math period.
On the third day of our exploration, I asked the children why they thought it was important to develop a standard form of measurement (or in words understandable to a first grader, a measurement that would always be the same size) such as using only "Zeb's foot" to measure everything. Through the discussions over the past several days, the children were able to internalize and verbalize the need or importance for everyone to measure using the same instrument. They saw the confusion of using different hands, bodies, or feet because of the inconsistency of size. (Hendry, 1996)
Questions:
1. Describe two similarities between the traditional lesson and the constructivist one as described above. What are two differences?
Both got the children involved where they were not sitting in a desk, also both encouraged the children to measure something and apply that knowledge to the model that was being modeled. Major differences would be that the traditionalist lesson was very short lived, it did not encourage curiosity, but rather limiting the amount of effort that the students could put forward. The constructivist lesson opened up with questions that probed the students thinking and encouraged them to apply what they already know to what they are trying to figure out. This lesson also went through several experiment processes that took place over a couple of days until the students were able to logically understand and apply the principals that were being taught.
2. What are two benefits and two drawbacks of the constructivist approach as described above? Why? In your opinion, are the benefits worth the costs? Explain your response.
Benefits would be that it opens up a lot of doors to the different types of learners that are existent, it also engages the students actively in the process. Drawbacks would be that there might be students who would not engage in the process, it could also have the possibility to get out of hand. I would put the benefits as being worth it, students especially students that are in the secondary level thrive in the actively engaged community. By giving them the opportunity to get out of their desk and participate and learn on their own assumptions but by doing so in a positive manner, the students will retain the knowledge better. I really enjoy getting my students out of their desk, they take a better approach and by doing an activity associate the knowledge better by remembering the activity.
3. How does the constructivist lesson described above promote critical thinking? Give specific examples of critical thinking from the case study and include a definition of critical thinking to support your response.

Cognitive Psychology/Information Processing Case Study Analysis
Case 1: Mr. West wants his students to truly understand Civil War battles. He engages the help of a local Historical Re-enactment Society and assigns each of his students to the Union or Confederate side. His students join the re-enactors from 7:00am-7:00pm for a full day of activities which include a long march (complete with rudimentary battle gear), setting up camp, cooking over campfires, scouting territory, and engaging in a historically representative battle.
1. After participating in this activity, what do you think the students will remember? How might those memories differ from those students would have if they only read about the Civil War in their textbook?
I would think that most of the students would be able to remember most of the activities that were done with the hands on approach. They are able to picture and be guided through interactive activities that provide them a visual representation of what might have happened in history. Students that only have the opportunity to read about and talk about things but not visually do and interact with them will not become actively engaged in the lesson and what they are being taught.
2. How does Mr. West’s use of a Civil War re-enactment engage students’ emotions? What is the relationship between emotions and learning?
It will be exciting for students to participate in this hands' on activity and get them actively engaged in what is being taught in the classroom. Their emotions will become positively charged presenting a positive transfer of information and making sure that they do fully engage in what is being taught. If a student is resistant and closed off emotionally it becomes extremely difficult for an educator to teach and get the students actively engaged. Learning is done in many ways through emotion providing either a positive or negative connotation to the information that is being presented.
3. Based on the principles of dual-coding theory, what activities would be effective for Mr. West to use as a follow-up to the re-enactment?
Mr. West has provided students with the chance to visually act out the history event that was being taught in class. This information would best be accompanied by a verbal accompaniment that does not compete with the visual presentation but rather the verbal information would build on the visual information. The verbal/reading component would have cement the topics that were presented in class and gives the students the opportunity to form the connections necessary for bridging those connections between the topics that are presented.
Case 2: Mr. Dunkin and Mr. Richards, teachers at the same school, are debating in the teacher’s lounge about who provides the best type of organization for the students’ learning. Mr. Dunkin lectures and assigns reading and chapter problems Mondays through Thursdays. On Fridays he gives a short answer exam. In Mr. Richards’ class the students never know what will take place on any given day until they arrive in class and look at a detailed outline of the hour’s activities on the chalkboard. His class engages in mix of role-plays, lecture, videos, group projects and demonstrations. Mr. Richards occasionally gives surprise quizzes and his unit tests can include true/false, multiple choice, short answer, or essay.
4. Who do you think provides better instruction for his students? Support your answer from an information processing perspective.
I would think that Mr. Richard's classes would be thriving more in the subject than the students in Mr. Dunkin's class. Although the students don't have a set schedule in the latter classes, the students in Mr. Richard's classes have the opportunity to do different activities that build upon different types of learning styles and do indeed get students actively engaged in the material. Mr. Richards' students are engaging in metacognition and the different learning transfer processes that do take place. They are learning through conscious attempts to build on new knowledge and taking that knowledge and building through activities and visual representations that help with increasing that knowledge rather than making them do strict book work.
5. How would you expect the students’ learning outcomes to differ depending on which teacher they had?
From my own personal experiences of teaching and working with kids that do have teachers that are very similar to these two presented, they do thrive in different learning situations based on their own learning styles and the different ways that they process information. It is also largely based upon on what level of learning they are at, what age group they are a part of. Students that only participate in bookwork, lectures, and reading do not retain information as well as students that become actively engaged in the classroom and do hands on activities that are not limiting the presentation of information to one outlet. Educators should be open to teaching new ways and working to adapt students to new ways of learning and new ways of presenting information.
