Calculating Words Read Correct Per Minute

Does anyone know how to calculate the words read correct per minute when checking a student's rate for oral fluency?

I am doing a research project and trying to figure this out. I intervened by modeling how to read fluently using echo and choral reading to first graders.

I used a stopwatch to time how many words each student read in one minute and then took that number and subtracted it by the number of errors made when reading. That gave me the number of words read correct per minute (WCPM). At least I think it did.

However, here's my problem...each book they read (guided reading books) varied in how many words were in each book. So, some books only had 26 words, others had 52 words, etc.

I hope someone knows how to do this and can help me determine if I am right. I would think the number of words read correctly would increase each time, but what if a book has only 26 words and they read all the words correctly while another book had 55 words and they read 51 words correctly in a minute. How does this show that they are improving in their readings?

Hope this makes sense. I am quite confused. Thanks so much!

First off, you should find passages because they will allow for more words per minute. I would not use the guided reading books because right now they are not reliable. We used our guided reading books in 4th grade, but they all were quite lengthy so it seemed ok!

I like the books 3 Minute Reading Assessments by Timothy Rasinski. You can find it on Amazon. They have a 1-4 book and a 5-8 book. You can also download the DIBELS online, which also has reading passages, at least for 1st grade and up. Those passages have between 200-400 words each. My very best readers last year would read like 160 maybe... I can't remember. Anyway, he passages don't need to be really long.

If the children are reading short books, you will have to give them a long passage to check with, because you can't know based on those books, especially if they only have 29 words in the whole book. My guess is that children reading books like that really need to focus on decoding and making meaning, and fluency comes later, when they are reading longer books. I don't work on fluency so much with my readers who have those little books. We are just working on learning to read them!

Basically, time the child reading for 1 minute from a passage. If you have a BOOK you want to use, find one with about 100 words or more. You will have to type the text of the book out so you can follow along. You mark any word that they skip, replace, say incorrectly, you help them with, etc. If they repeat the word, or self-correct the word it's counts as a correctly read word.

Say the child reads 63 words in one minute, and reads 59 of them correctly. You only count the words read correctly. Divide the two numbers and you will have their fluency % rate. In this case the child has a 93% fluency rate, and that would be ok for instructional reading. I think 96% and above is good for independent reading and below 90% is too hard... but someone else may correct me on that!

You could take a trade book at the level your child is reading and see if it has more words than the guided reading books. If not, my guess is that the children are really too low to be doing this kind of oral reading work with.

Also, if you have a subscription to Reading A-Z they have fluency passages on it.

Here are some other websites with passages:

http://terpconnect.umd.edu/~dlspeece...de1/index.html

http://www.readinga-z.com/guided/fluency.html (Even if you don't have a subscription, this will explain to you about how to do a fluency passage w/ a child.)

http://terpconnect.umd.edu/~dlspeece...de3/index.html

http://terpconnect.umd.edu/~dlspeece...de4/index.html

https://dibels.uoregon.edu/

You can sign up for this and print out their materials... it's A LOT of paper. We use them at our school. But, I think they also have practice passages you can print out... I haven't used them but I think I saw them on the site.

Correct, but If I have someone reading at a 98% fluency rate with a very low comprehension, I would still instruct them at that level - if that makes sense.

Thanks for the tip MissFroggy. However, I already collected my data using my guided reading books per my professors suggestions. I teach a Modified Reading Recovery program so my professor told us to pick an action research project that was in the locust of our classroom situations.

In the future, I will definitely look into your websites. However, I cannot go back and collect new data now because my assignment is due Wednesday and my professor said this would be fine. She wasn't exactly positive off the top of her head how to calculate the number of words read correct (WCPM) so I looked online.

Can anyone else tell me whether I did this okay or not?

Thanks so much! The more I look at this, the more confused I get.

For example, a child read 55 words in one minute but made 4 errors. What I did was...

55 words per minute minus 4 errors = 51 words

So, 51 words became the number of words they read in a minute. That is what I would use for their WCPM for that reading?

Is this right?

Well one thing you could do, though not really the best way to figure this statistic is figure the number on a per minute basis. If they read 29 words correct in say 40 seconds, you would need to convert to what that would be if they actually read for a minute. So you need to figure out how many words they read per second and mulitply by 60. In the above example:

40 seconds divided by 29 words read =1.38 words per second

1.38 words per second x 60 seconds=82.8 words per minute.

Yes if they read for a full minute then that is correct. You need to adjust if they read for less than a minute.

You might give one child a book with 55 words and he read 51 words correct and did it in 45 seconds. That student is actually reading more words correct per minute that the student you just referenced.

My problem always comes when the child reads the entire passage in less than a minute.
Say the passage has 55 words and they read it in 45 seconds. They are reading more than 55 words per minute. When this happens, I use this equation:

55 X
60 45

or I mulitply 55 times 60 then divide by 45 .
I time them at their instructional level. If they consistantly score above 90 words per minute, and their comprehension is there too, I generally bump them up to the next level.

Of course you can change it into a percentage once you figure the actual number.
