1 Rate of Improvement Calculation and Decision Making
Caitlin S. Flinn, EdS, NCSP Andrew E. McCrea, MS, NCSP

2 Why we’re here… While there exists a wealth of convincing research supporting the implementation of a response-to-intervention (RtI) framework, there are many questions yet to be empirically answered. Within multi-tiered model of assessment and instruction/intervention, how do we know whether a student is learning?

3 Measuring Learning Class tests Quizzes
Assignment/homework completion and accuracy Ask students questions in class Grades/report cards State/local assessments Universal screening, benchmark assessments Progress monitoring

4 With Progress Monitoring Data…
How do we know if a student is learning? Look at the data points Where are they on the graph? Are the data points getting closer to the goal or benchmark? Is there a way to measure growth? Make an aimline toward goal Look to see where data points are compared to aimline Calculate Rate of Improvement (RoI)

5 Today’s Objectives Explain what RoI is, why it is important, and how to compute it. Establish that Simple Linear Regression should be the standardized procedure for calculating RoI. Discuss how to use RoI within a problem solving/school improvement model.

6 RoI Definition Rate of Improvement can be described algebraically as the slope of a line Slope is defined as: the vertical change over the horizontal change on a Cartesian plane. (x-axis and y-axis graph) Also called: Rise over run Formula: m = (y2 - y1) / (x2 - x1) Describes the steepness of a line (Gall & Gall, 2007)

7 RoI Definition Finding a student’s RoI is determining the student’s learning Creating a line that fits the data points, a trendline To find that line, we use: Linear regression Ordinary Least Squares

8 How does Rate of Improvement Fit into the Larger Context?

9 School Improvement/Comprehensive School Reform
Response to Intervention Dual Discrepancy: Level & Growth Rate of Improvement

10 School Improvement/ Comprehensive School Reform
Grade level content expectations (ELA, math, science, social studies, etc.). Work toward these expectations through classroom instruction. Understand impact of instruction through assessment.

11 Assessment Formative Assessments/High Stakes Tests
Does student have command of content expectation (standard)? Universal Screening using CBM Does student have basic skills appropriate for age/grade?

12 Assessment Q: For students who are not proficient on grade level content standards, do they have the basic reading/writing/math skills necessary? A: Look at Universal Screening; if above criteria, intervention geared toward content standard, if below criteria, intervention geared toward basic skill.

13 Progress Monitoring Frequent measurement of knowledge to inform our understanding of the impact of instruction/intervention. Measures of basic skills (CBM) have demonstrated reliability & validity (see table at

14 Classroom Instruction (Content Expectations)
Measure Impact (Test) Proficient! Non Proficient Use Diagnostic Test to Differentiate Content Need? Basic Skill Need? Intervention Progress Monitor Intervention Progress Monitor With CBM If CBM is Appropriate Measure Rate of Improvement

15 So… Rate of Improvement (RoI) is how we understand student growth (learning). RoI is reliable and valid (psychometrically speaking) for use with CBM data. RoI is best used when we have CBM data, most often when dealing with basic skills in reading/writing/math. RoI can be applied to other data (like behavior) with confidence too! RoI is not yet tested on typical Tier I formative classroom data.

16 RoI is usually applied to…
Tier One students in the early grades at risk for academic failure (low green kids). Tier Two & Three Intervention Groups. Special Education Students (and IEP goals) Students with Behavior Plans Love the tractor

17 RoI Foundations Deno, 1985 Curriculum-based measurement
General outcome measures Technically adequate Short Standardized Repeatable Sensitive to change

18 RoI Foundations Fuchs & Fuchs, 1998
Hallmark components of Response to Intervention Ongoing formative assessment Identifying non-responding students Treatment fidelity of instruction Dual discrepancy model One standard deviation from typically performing peers in level and rate

19 RoI Foundations Ardoin & Christ, 2008
Slope for benchmarks (3x per year) More growth from fall to winter than winter to spring Might be helpful to use RoI for fall to winter And a separate RoI for winter to spring

20 RoI Foundations Fuchs, Fuchs, Walz, & Germann, 1993
Typical weekly growth rates in oral reading fluency and digits correct Needed growth to remediate skills Students who had 1.5 to 2.0 times the slope of typically performing peers were able to close the achievement gap in a reasonable amount of time

21 RoI Foundations Deno, Fuchs, Marston, & Shin, 2001
Slope of frequently non-responsive children approximated slope of children already identified as having a specific learning disability

22 How many data points? 10 data points are a minimum requirement for a reliable trendline (Gall & Gall, 2007) Is that reasonable and realistic? How does that affect the frequency of administering progress monitoring probes? How does that affect our ability to make instructional decisions for students?

23 How can we show RoI? Speeches that included visuals, especially in color, improved recall of information (Vogel, Dickson, & Lehman, 1990) “Seeing is believing.” Useful for communicating large amounts of information quickly “A picture is worth a thousand words.” Transcends language barriers (Karwowski, 2006) Responsibility for accurate graphical representations of data

24 Skills for Which We Compute RoI
Reading Oral Reading Fluency Word Use Fluency Reading Comprehension MAZE Retell Early Literacy Skills Initial Sound Letter Naming Letter Sound Phoneme Segmentation Nonsense Word Spelling Written Expression Behavior Math Math Computation Math Facts Early Numeracy Oral Counting Missing Number Number Identification Quantity Discrimination

25 Guidelines? Visual inspection of slope Multiple interpretations
Instructional services Need for explicit guidelines

26 Ongoing Research RoI for instructional decisions is not a perfect process Research is currently addressing sources of error: Christ, 2006: standard error of measurement for slope Ardoin & Christ, 2009: passage difficulty and variability Jenkin, Graff, & Miglioretti, 2009: frequency of progress monitoring

27 Future Considerations
Questions yet to be empirically answered What parameters of RoI indicate a lack of RtI? How does standard error of measurement play into using RoI for instructional decision making? How does RoI vary between standard protocol interventions? How does this apply to non-English speaking populations?

28 How is RoI Calculated? Which way is best?

29 Multiple Methods for Calculating Growth
Visual Inspection Approaches “Eye Ball” Approach Split Middle Approach Tukey Method Quantitative Approaches Last point minus First point Approach Split Middle & Tukey “plus” Linear Regression Approach

30 The Visual Inspection Approaches

31 Eye Ball Approach

32 Split Middle Approach Drawing “through the two points obtained from the median data values and the median days when the data are divided into two sections” (Shinn, Good, & Stein, 1989).

33 Split Middle X(14) X (9) X(9)

34 Tukey Method Divide scores into 3 equal groups
Divide groups with vertical lines In 1st and 3rd groups, find median data point and median week and mark with an “X” Draw line between two “Xs” (Fuchs, et. al., Summer Institute Student progress monitoring for math.

35 Tukey Method X(14) X(8)

36 The Quantitative Approaches

37 Last minus First Iris Center: last probe score minus first probe score over last administration period minus first administration period. Y2-Y1/X2-X1= RoI

38 Last minus First

39 Split Middle “Plus” X(14) X(9) (14-9)/8=0.63

40 Tukey Method “Plus” X(14) X(8) (14-8)/8=0.75

41 Linear Regression

42 Any Method of Visual Inspection
RoI Consistency? Any Method of Visual Inspection ??? Last minus First 0.75 Split Middle “Plus” 0.63 Tukey “Plus” Linear Regression 1.10

43 RoI Consistency? If we are not all using the same model to compute RoI, we continue to have the same problems as past models, where under one approach a student meets SLD criteria, but under a different approach, the student does not. Hypothetically, if the RoI cut-off was 0.65 or 0.95, different approaches would come to different conclusions on the same student.

44 Difference in RoI b/w LmF & LR Methods
RoI Consistency? Last minus First (Iris Center) and Linear Regression (Shinn, etc.) only quantitative methods discussed in CBM literature. Study of 37 at risk 2nd graders: Difference in RoI b/w LmF & LR Methods Whole Year 0.26 WCPM Fall 0.31 WCPM Spring 0.24 WCPM McCrea (2010) Unpublished data

45 Technical Adequacy Without a consensus on how to compute RoI, we risk falling short of having technical adequacy within our model.

46 So, Which RoI Method is Best?

47 Literature shows that Linear Regression is Best Practice
Student’s daily test scores…were entered into a computer program…The data analysis program generated slopes of improvement for each level using an Ordinary-Least Squares procedure (Hayes, 1973) and the line of best fit. This procedure has been demonstrated to represent CBM achievement data validly within individual treatment phases (Marston, 1988; Shinn, Good, & Stein, in press; Stein, 1987). Shinn, Gleason, & Tindal, 1989

Summarizing trend in student achievement: A comparison of methods. School Psychology Review, 18,

50 So, Why Are There So Many Other RoI Models?
Ease of application Focus on Yes/No to goal acquisition, not degree of growth How many of us want to calculate OLS Linear Regression formulas (or even remember how)?

51 Pros and Cons of Each Approach
Eye Ball Easy Understandable Subjective Split Middle & Tukey No software needed Compare to Aim/Goal line Yes/No to goal acquisition No statistic provided, no idea of the degree of growth

52 Pros and Cons of Each Approach
Last minus First Provides a growth statistic Easy to compute Does not consider all data points, only two Split Middle & Tukey “Plus” Considers all data points. No support for “plus” part of methodology Linear Regression All data points Best Practice Calculating the statistic

74 Individual Student Graph: Fall to Winter

75 Individual Student Graph
The equation indicates the slope, or rate of improvement. The number, or coefficient, before "x" is the average improvement, which in this case is the average number of words per minute per week gained by the student.

76 Individual Student Graph
The rate of improvement, or trendline, is calculated using a linear regression, a simple equation of least squares. To add additional progress monitoring/benchmark scores once you’ve already created a graph, enter additional scores in Row 5 in the corresponding school week.

77 Individual Student Graph
The slope can change depending on which week (where) you put the benchmark scores on your chart. Enter benchmark scores based on when your school administers their benchmark assessments for the most accurate depiction of expected student progress.

108 Assuming Linear Growth…
Why Graph only 18 Weeks at a Time? Assuming Linear Growth… …Finding Curve-linear Growth

109 Non-Educational Example of Curve-linear Growth

110 Academic Example of Curvilinear Growth

111 McCrea, 2010 Looked at Rate of Improvement in small 2nd grade sample
Found differences in RoI when computed for fall and spring: Ave RoI for fall: WCPM Ave RoI for spring: 1.21 WCPM

112 Ardoin & Christ, 2008 Slope for benchmarks (3x per year)
More growth from fall to winter than winter to spring

113 Christ, Yeo, & Silberglitt, in press
Growth across benchmarks (3X per year) More growth from fall to winter than winter to spring Disaggregated special education population

115 Fien, Park, Smith, & Baker, 2010 Investigated relationship b/w NWF gains and ORF/Comprehension Found greater NWF gains in fall than in spring.

118 Speculation as to why Differences in RoI within the Year
Relax instruction after high stakes testing in March/April; a PSSA effect. Depressed BOY benchmark scores due to summer break; a rebound effect (Clemens). Instructional variables could explain differences in Graney (2009) and Ardoin (2008) & Christ (in press) results (Silberglitt). Variability within progress monitoring probes (Ardoin & Christ, 2008) (Lent).

124 Step 2: Ground the Data 1) To what will we compare our student growth data? 2) How will we set goals?

125 Multiple Ways to Look at Growth
Needed Growth Expected Growth & Percent of Expected Growth Fuchs et. al. (1993) Table of Realistic and Ambitious Growth Growth Toward Individual Goal* *Best Practices in Setting Progress Monitoring Goals for Academic Skill Improvement (Shapiro, 2008)

126 Needed Growth Difference between student’s BOY (or MOY) score and benchmark score at MOY (or EOY). Example: MOY ORF = 10, EOY benchmark is 40, 18 weeks of instruction (40-10/18=1.67). Student must gain 1.67 wcpm per week to make EOY benchmark.

127 Expected Growth Difference between two benchmarks.
Example: MOY benchmark is 20, EOY benchmark is 40, expected growth (40-20)/18 weeks of instruction = 1.11 wcpm per week.

128 Looking at Percent of Expected Growth
Tier I Tier II Tier III Greater than 150% Between 110% & 150% Possible LD Between 95% & 110% Likely LD Between 80% & 95% May Need More Below 80% Needs More Tigard-Tualatin School District (www.ttsd.k12.or.us)

129 Oral Reading Fluency Adequate Response Table
Realistic Growth Ambitious Growth 1st 2.0 3.0 2nd 1.5 3rd 1.0 4th 0.9 1.1 5th 0.5 0.8 Fuchs, Fuchs, Hamlett, Walz, & Germann (1993)

130 Digit Fluency Adequate Response Table
Realistic Growth Ambitious Growth 1st 0.3 0.5 2nd 3rd 4th 0.75 1.2 5th Fuchs, Fuchs, Hamlett, Walz, & Germann (1993)

131 If Local Criteria are Not an Option
Use norms that accompany the measure (DIBELS, AIMSweb, etc.). Use national norms.

132 Making Decisions: Best Practice
Research has yet to establish a blue print for ‘grounding’ student RoI data. At this point, teams should consider multiple comparisons when planning and making decisions.

133 Making Decisions: Lessons From the Field
When tracking on grade level, consider an RoI that is 100% of expected growth as a minimum requirement, consider an RoI that is at or above the needed as optimal. So, 100% of expected and on par with needed become the limits of the range within a student should be achieving.

134 Is there an easy way to do all of this?

135

136

137 Access to Spreadsheet Templates
Click on Charts and Graphs. Update dates and benchmarks. Enter names and benchmark/progress monitoring data.

138 What about Students not on Grade Level?

139 Determining Instructional Level
Independent/Instructional/Frustrational Instructional often b/w 40th or 50th percentile and 25th percentile. Frustrational level below the 25th percentile. AIMSweb: Survey Level Assessment (SLA).

140 Setting Goals off of Grade Level
100% of expected growth not enough. Needed growth only gets to instructional level benchmark, not grade level. Risk of not being ambitious enough. Plenty of ideas, but limited research regarding Best Practice in goal setting off of grade level.

141 Possible Solution (A) Weekly probe at instructional level and compare to expected and needed growth rates at instructional level. Ambitious goal: 200% of expected RoI

142

143 Possible Solution (B) Weekly probe at instructional level for sensitive indicator of growth. Monthly probes (give 3, not just 1) at grade level to compute RoI. Goal based on grade level growth (more than 100% of expected).

144 Step 3: Interpreting Growth

145 What do we do when we do not get the growth we want?
When to make a change in instruction and intervention? When to consider SLD?

146 When to make a change in instruction and intervention?
Enough data points (6 to 10)? Less than 100% of expected growth. Not on track to make benchmark (needed growth). Not on track to reach individual goal.

147 When to consider SLD? Continued inadequate response despite:
Fidelity with Tier I instruction and Tier II/III intervention. Multiple attempts at intervention. Individualized Problem-Solving approach. Evidence of dual discrepancy…

148

149 Three Levels of Examples
Whole Class Small Group Individual Student - Academic Data - Behavior Data

150 Whole Class Example

151 3rd Grade Math Whole Class
Who’s responding? Effective math instruction? Who needs more? N=19 4 > 100% growth 15 < 100% growth 9 w/ negative growth

152 Small Group Example

153 Intervention Group Intervention working for how many?
Can we assume fidelity of intervention based on results? Who needs more?

154 Individual Kid Example

155 Individual Kid Making growth? How much (65% of expected growth).
Atypical growth across the year (last 3 data points). Continue? Make a change? Need more data?

156 RoI and Behavior?                                                               

157

158 Step 4: Figure out how to fit Best Practice into Public Education

159 Things to Consider Who is At-Risk and needs progress monitoring?
Who will collect, score, enter the data? Who will monitor student growth, when, and how often? What changes should be made to instruction & intervention? What about monitoring off of grade level?

160 Who is At-Risk and needs progress monitoring?
Below level on universal screening Entering 4th Grade Example DORF (110) ISIP TRWM (55) 4Sight (1235) PSSA (1235) Student A 115 58 1255 1232 Student B 85 48 1216 1126 Student C 72 35 1056 1048

161 Who will collect, score, and enter the data?
Using MBSP for math, teachers can administer probes to whole class. DORF probes must be administered one-on-one, and creativity pays off (train and use art, music, library, etc. specialists). Schedule for progress monitoring math and reading every-other week.

162 Week 1 Week 2 Reading Math 1st X 2nd 3rd 4th 5th

163 Who will monitor student growth, when, and how often?
Best Practices in Data-Analysis Teaming (Kovaleski & Pedersen, 2008) Chambersburg Area School District Elementary Response to Intervention Manual (McCrea et. al., 2008) Derry Township School District Response to Intervention Model (http://www.hershey.k12.pa.us/ /lib/ /_files/Microsoft_Word_-_Response_to_Intervention_Overview_of_Hershey_Elementary_Model.pdf)
