The significance of formative evaluation in mathematical drawback fixing


“When the prepare dinner tastes the soup, that is formative; when the company style the soup, that is summative.”

-Robert Stake

From the presentation by Lynda Watters and Jill Sanderson, 2016

Our grade 1/2 trainer (Jill Sanderson) and our grade 4 trainer (Lynda Watters) had been gracious sufficient to place collectively an influence level presentation of their studying from the CAFLN (Canadian Evaluation for Studying Community) convention they attended. Of their presentation they talked about that Formative Evaluation would not must contain a whole lot of paper work however somewhat simply taking the time to look at and talk (ask questions somewhat than giving solutions), with college students about their work.  

Through the presentation, Jill (grade 1/2 trainer) handed out a duplicate of a math drawback query that she determined to attempt together with her class having seen it on the convention. She requested us to have a look at the kid’s illustration and ponder what this youngster knew? What questions would we ask her? How might we assist her studying additional?

Typically we really feel the necessity to steer kids in the direction of appropriate solutions somewhat than taking the time to look at their work and reply questions with additional inquiries to assist studying and understanding. 

In response to the Pure Curiosity useful resource, Evaluation for Studying is printed as the next:

  • the method of gathering and analyzing proof to be used by college students and their trainer to find out the place college students are of their studying, the place they should go, and the way greatest to get there.
  • helps lecturers differentiate and focus learn how to method the training of particular person college students 

(Pure Curiosity: Constructing Kids’s Understanding of the World via Environmental Inquiry/A Useful resource for Lecturers, web page 30).

I made a decision to take this query and ask it to my kindergarten college students. I used to be enthusiastic about studying in the event that they understood the query, the completely different methods they could select to make use of to resolve it, and the way they’d exhibit their solutions.

Check out the photographs beneath. What do you deduce from every of their representations? What do every of them let you know about their information and understanding of the query? How can these representations support in supporting pupil studying additional? 

“Suggestions might be the important hyperlink between the lecturers’ evaluation of a kid and the motion following that evaluation, which then has a formative impact on the kid’s studying.” -Hargreaves et al. (2000)

From the presentation by Lynda Watters and Jill Sanderson, 2016


The scholars loved the problem query. After sharing their work with their friends I made a decision to attempt a couple of extra questions with them.

A dice illustration of twenty bees every with 4 wings. 

D tried to make use of cubes to depict twenty bees every with 4 wings. This was a superb begin however he requested Z if he would assist him together with his counting as he saved getting caught. Discover the best way they used the cubes to characterize the main points within the query. 


This time I shared a query that required listening to two traits, variety of legs and variety of trunks. I once more requested the scholars how we might determine this out?

After I seen E’s illustration, I used to be proud that he understood to attract ten elephants. He additionally added one trunk and 4 legs for every elephant. He grew to become drained and didn’t end fixing the issue. However this drawing alone is filled with details about his understanding of the query and his quantity sense. 

  

At first she made ten items of wire with beads on them. She instructed me she was achieved. I then requested her to clarify to me what the completely different colored beads represented? What number of elephants do we’d like? She instructed me that the 4 beads represented the legs and the inexperienced bead represented the trunk for every elephant. In telling me this she began to depend the elephants and realized she made too many.

With this query I made a decision to not focus on as a gaggle as I needed to see if any of the scholars took a few of their studying methods from the earlier questions and associated them to fixing this query. 

There are 15 flowers in my vase. Every flower has 5 petals. What number of petals altogether?

M selected to make use of cubes to characterize the flowers and petals. M instructed me he positioned these in rows of 5 although he nonetheless selected to depend the flowers and petals by one’s. 

In her drawing illustration, M knew to attract fifteen flowers. She instructed me she needed to scratch some out as she realized she made a mistake and drew too many. Her telling me this info was crucial because it instructed me so much about her counting potential and her potential to determine when issues didn’t add up appropriately. You may see that she knew to attract 5 petals per flower however once more she instructed me she drew too many on some and he or she had to return and scratch them out. Checking over one’s work is a crucial ability to have and I observed that M was in a position to do that independently. She grew to become a bit drained so she didn’t end determining the reply. However this isn’t at all times crucial side as there may be a lot that’s gained from even making an attempt. 

A created a stunning illustration utilizing poker chips. He made fifteen flowers every with 5 petals. He used jewels for the centre of every flower which he didn’t depend as a petal. I noticed him counting the petals and observed he was counting by one’s. Although we have now achieved some work on counting by 2’s, 5’s, and 10’s. It appears this methodology of counting is the essentially the most reassuring for him.

As a enjoyable math problem I confirmed the video beneath to the youngsters. I obtained the hyperlink to this math drawback from Lynda Watters (grade 4 trainer) who obtained it from Lynn Strangway (TDSB Principal) and Dianne Riehl (TDSB Vice Principal). She knowledgeable me the maths drawback was explored by a grade 1/2 class. I needed to know what a number of the kindergarten college students thought after viewing it a couple of instances and accessing the usage of supplies.

Ideas after first viewing:


“He sorted by half and cut up them.” Ok. C.

“He mentioned one for him and one for his greatest buddy to make it equal.” L. B.

“All of his buddies and him go the identical quantity.” D. F.

“However not his sister, she solely acquired 5.” B. P.

“He cut up in half for this buddies.” C. T.

Thought after second viewing:

“I observed that what number of he acquired appears to be like similar to ten.” J. Ok.

“When he divided together with his buddies they acquired the identical quantity however not his child sister or him.” C. C.

“I observed he shared.” E. B.

“Each time he cut up he had some left and the leftovers he saved splitting so his buddies get the identical quantity.” Z. G.

“He did a sample, one for you and one for me.” C. D.

“He cut up with 4 folks.” F. D.

After viewing the video a couple of instances, I requested the scholars if anybody needed to make use of the lids to discover this math drawback additional? Under is C. C. and Z. G.’s expertise.

“We made Charlie’s gumballs. We counted by ten. We figured what number of Charlie had. We put one after the other. Every bag has forty gumballs. 4 gumballs for Charlie. 5 gumballs for his little sister.” L. S. and A. R.

The video beneath was from the morning exploration. The pictures above are from the identical day however through the afternoon. Within the afternoon the ladies discovered extra lids and determined to separate the “gumballs” once more.

What math language information are they utilizing? What do the 2 college students perceive about this math drawback? What can be a potential subsequent step to increase their studying?

A well timed query because it was pizza lunch day! We had been curious as to what number of items of pizza everybody ate. I requested the youngsters to recollect what number of slices they ate. We recorded the knowledge and acquired an entire bunch of numbers! I then requested them, “What are some completely different methods you could possibly use to attempt to work out what number of items of pizza we ate altogether?”.

C. C. and E. B. determined to make use of a ten body to assist them add up all of the numbers. They test off every time they added chips onto the ten body that coincided with the knowledge on the chart paper.


Each C. C. and E. B. did their very own counting utilizing ten frames. What do you discover in the best way they represented their information? 

F. D. mentioned that she needed to depend by two’s then depend the one’s and add the 2 numbers collectively. I provided her the quantity chart to assist her in including the 2 numbers she acquired collectively. 



C. D. and S. T. needed to attract pizza slices to characterize the information on the chart stand. After they drew all of the pizza slices they counted the slices to get the entire slices.

What info can you’re taking away from the three completely different methods used? What additional helps might be provided to the scholars? How can their considering and studying be prolonged? I discover myself asking these questions usually. They’re a superb information for me to mirror on the considering and studying of every pupil.

It is essential that we place simply as a lot worth on making pupil considering and studying seen somewhat than specializing in the ultimate product so we are able to higher differentiate the assist and steerage wanted by each youngster.     

“What if we began from a spot the place studying was seen as an interplay during which two or extra people work collectively in an mental strategy to remedy an issue, make clear an idea, mirror, prolong a story, and so on. Each events should contribute to the considering and it should develop and prolong, in different phrases, negotiated studying.”
