1 1 Introduction To The Middle School Data Team This Demo Uses Fictional Data For Purposes of Example The Ultimate Goal is to Answer Your Questions with Your Data DataTeamConsulting.Com

2 2 Middle School Data Team Purpose of the Data Team The purpose of the Middle School data team is to use quantitative and qualitative data, as much as possible, to improve teaching and learning. Members of the Data Team The purpose of this presentation is to invite you to become a member of the data team. To provide a taste of the possibilities, we will present one line of inquiry of interest to the current members. The current members: Roberto da Costa Samuel Guthrie Xian Coy Manh Danielle Moonstar Sean Parker (consultant) Rahne Sinclair DataTeamConsulting.Com

3 3 How well do 5 th grade Math MCAS scores predict 6 th grade Math MCAS scores? Scatterplot of 6 th grade math scores vs. 5 th grade math scores (n = 159). We will use MCAS scale scores. 220 = N.I. 240 = Prof. 260 = Adv. Warning/Failing Needs Improvement Proficient Advanced DataTeamConsulting.Com

4 4 Initials: L.H. Math MCAS 5 th Grade: th Grade: 248 Initials: J.P. Math MCAS 5 th Grade: th Grade: 224 Initials: R.K. Math MCAS 5 th Grade: th Grade: 268 What does the scatterplot tell us? Initials: F.J. Math MCAS 5 th Grade: th Grade: 228 Initials: L.M. Math MCAS 5 th Grade: th Grade: 274 Scatterplot of 6 th grade math scores vs. 5 th grade math scores (n = 159).

5 5 Each data point is a small part of a much larger story. Scatterplot of 6 th grade math scores vs. 5 th grade math scores (n = 159). DataTeamConsulting.Com

6 6 We can make predictions based on the (limited) data. Scatterplot of 6 th grade math scores vs. 5 th grade math scores (n = 159). DataTeamConsulting.Com

7 7 The prediction line is pulled by every observation. Scatterplot of 6 th grade math scores vs. 5 th grade math scores (n = 159). DataTeamConsulting.Com

8 8 Once we have a prediction line, we can use it to make predictions. Example: For students who score 240 on the 5th grade Math MCAS, we predict that they will score 242 on the 6th grade Math MCAS. Of course, some students do much better (or worse) than our prediction. 242 Scatterplot of 6 th grade math scores vs. 5 th grade math scores (n = 159). DataTeamConsulting.Com

9 9 We can also use the prediction to identify students who break the pattern. Example: Some students do much better on the 6 th grade Math MCAS than we would predict based on their 5 th grade scores. Is there a pattern within the pattern?

10 10 Is there a pattern within the pattern? We have two valuable resources to answer this question. First and foremost, we have teachers with deep professional knowledge of these students. For example, if given a list of names of students who do better than predicted, teachers may be able to discern commonalities and perhaps causes. Secondly, we have additional quantitative information that we can bring to bear. For example, first semester grades provide information over and above the previous years MCAS score. (Note that numbers alone cannot get at causes unless we have random treatment and control groups.) For grades, we will use an average of English, social studies, math and science, because we know that all subjects are correlated with all MCAS tests. (We will include more subjects in the average as we get the data.) DataTeamConsulting.Com

11 11 Using grades to uncover the pattern within the pattern. Students who earned an A in their first semester at Middle School: RED DataTeamConsulting.Com

12 12 Using grades to uncover the pattern within the pattern. A Students who earned an A in their first semester at Middle School: REDStudents who earned a B in their first semester at Middle School: Blue DataTeamConsulting.Com

13 13 Using grades to uncover the pattern within the pattern. A B Students who earned a B in their first semester at Middle School: BlueStudents who earned a C in their first semester at Middle School: Green DataTeamConsulting.Com

14 14 Using grades to uncover the pattern within the pattern. A B C Students who earned a C in their first semester at Middle School: Green DataTeamConsulting.Com

15 15 We can use the prediction lines to make predictions. A B C The previous years MCAS score is not destiny. Example: For students who score 240 on the 5th grade Math MCAS, we predict differently depending on how they perform in the first semester of the 6 th grade Predicted 6 th grade math scores based on 5 th grade math scores and first-semester grades. DataTeamConsulting.Com

16 16 We can use this information to flag students who may need extra help. A B C Example: Almost all students who earn a C in the first semester of the 6 th grade are at risk of scoring less than 240, regardless of how they scored on the 5 th grade math MCAS. Predicted 6 th grade math scores based on 5 th grade math scores and first-semester grades.

17 17 Some students break the pattern, and teachers can see who. A B C Example: Some students do much better on the 6 th grade Math MCAS than we would predict based on 5 th grade scores and first term grades. Predicted 6 th grade math scores based on 5 th grade math scores and first-semester grades. DataTeamConsulting.Com

18 18 We can construct plots for not only Math MCAS but also for ELA MCAS. Predicted 6th grade MCAS scores based on 5th grade scores and first-semester grades. MathELA DataTeamConsulting.Com

19 19 We can also construct plots to predict 7 th grade scores. Predicted 7 th grade MCAS scores based on 6 th grade scores and first-semester grades. MathELA DataTeamConsulting.Com

20 20 We can also construct plots to predict 8 th grade scores. Predicted 8 th grade MCAS scores based on 7 th grade scores and first-semester grades. MathELA DataTeamConsulting.Com

21 21 Future Lines of Inquiry Future lines of inquiry for the data team: Does the MCAS/grades pattern hold up across the years? (The current patterns are based on one cohort.) What other factors do we need to consider? E.g., special education status, free lunch eligibility, classroom conduct as assessed by teachers. Based on professional experience and knowledge, what are the potential causes? How can we dig deeper into the causes using qualitative and quantitative data? Future lines of inquiry for an action team: What policies and interventions do the data suggest? (The data team and the action teams should be separate. The purpose of the data team should be informative.) DataTeamConsulting.Com
