I opted to use Google Spreadsheet
to make my student data spreadsheet. I have used various spreadsheet programs before but I do not create them often. I think it would be difficult for teachers to dedicate the time to using a spreadsheet like this unless the information was already available online and could be merged or even cut and pasted into a program. I find the number of formulas available to be overwhelming at first. It took me a while to figure out how to use a =countif formula to determine the number of correct responses per question.

Support using formulas can be found at this link. |
I also wanted to sort the data by Strand. I decided that having it sorted that way was going to be more helpful to the teacher than just the question number. In an attempt to make this stand out more, I opted to highlight by strand also. I also alphabetized the list which will make it easier for the teacher to find her student by name. Any additional students who are added to the list will be alphabetized also. This is done by sorting the range highlighted. It's important not to sort the entire page by mistake.

This is a screen grab of the Data drop down menu for sorting a range. Simply highlight the range that you want sorted. |
Many people are not used to looking at spreadsheet so color coding can be helpful. I chose red for the incorrect responses. This gives a visually quick look at the overall question. This was accomplished by using a conditional formatting. The formatting functions found here are extremely helpful for sorting and extrapolating data. Conditional formatting is like an "If, Then" question. I formulated it by saying that "If the text is exactly B (or what ever the correct response was) Then the print was in Black. Then you have to add, "Text does not contain B (or whatever the correct response was) Then print was in Red.
I might also have noted questions that gave a consistent incorrect answer (i.e. 80% of the incorrect responses answered "B".) This information could be helpful to a teacher who is trying to determine why a student answered incorrectly. This would be most helpful in specifically reteaching a particular point.
In this particular data, there were 2 questions that over 80% of the students answered incorrectly. This type of information helps to inform the next steps taken by the teacher, including when to refocus and reteach concepts missed by that many students. I could see how breaking down data can help to inform instruction within the class, grade or school. At our school we often spend staff meeting time extrapolating information out of standardized testing scores. This can be cumbersome but in many cases allows us to target specific areas that need additional support. At the classroom level, this information could be collected from summative assessments in an attempt to make sure that the students fully understand the concepts being taught.
besides the countif() formula you could run the if() formula to auto correct. For example. If the student answer is in A2 and is C, and the correct answer is stored in B2 and is B. You could run =IF(a2=b2,"yes","no") Where "yes" is spit back if the argument a2=b2 is true, and "no" if false. You could replace "yes" and "no" with anything, even the appropriate point values. That's where using Google forms to present mini quizzes to auto correct is very useful. The form will associate with a spreadsheet, the IF() formula could be set up so as responses come in, the spreadsheet auto corrects the students responses. Pretty handy when you need quick formative feedback.
ReplyDeleteYou mention that analyzing standardized scores can be cumbersome, true, but imagine how the use of a collaborative tool like Google spreadsheets allows for all teachers to manipulate the data and look at it from different angles. You could make a "master" tab in the spreadsheet that is locked from edits, but teachers could reference the data with formulas, and be able to do some interesting analysis.
I had not really thought about consistent incorrect answers, and the results of such findings, on instruction. Test results are not something that I have used extensively to modify instruction. When I taught Montessori, observation was the primary assessment. Now that I teach computer technology, the assessments are project based. Thanks for pointing that out:)
ReplyDeleteIt is interesting that when grouped by strand, there doesn't seem to be much correlation within the strands for the number of incorrect answers. Formulas are a little scary when you start using them, but if you break them down they are really pretty logical.
ReplyDeleteI like how you actually inputted the student answers into your spreadsheet and conditionally formatted them based upon if they were correct or not. This could be very helpful in finding trends in mistaken operations or common miscomputations. I also like that you added a link for teachers to find out how to use formulas. This will be helpful for teachers just starting with using a spreadsheet. Great job!
ReplyDeleteI really liked the grouping of the standards...didn't think of that. Also formatting so that the correct and incorrect answers were obvious is awesome. The links for other educators was very helpful. I too had some time with the formulas but found that it was worth the effort because the information could be very beneficial for some educators. Nice job.
ReplyDeleteJenn, thanks for the explanation for the countif formula. I might just have to go back and calculate percentages now! I need to become more familiar with what the formulas mean before the help page will be helpful. I also did the conditional formatting and set up the unused cells for future data. I added a rule that if the cell was blank to leave it highlighted white - I didn't realize this until afterwards. I wish there was an easy way to rearrange the rules.
ReplyDeleteGreat post,
Megan
Sorting spreadsheets is a great tool to understand and utilize. Being able to sort students by name is essential in the data collection process, and can also be useful in other areas of the classroom. As a Unified Arts teacher, I have about 25 different classes each week. This means I have 25 different rosters. Being able to add new students into my roster, and sort the database to organize and add new students is very important and useful. I like how you were able to sort and organize your data for the Data Collection project.
