Response to Intervention Apply the ‘ 80 -15 -5’ Rule to Determine if the Focus of the Intervention Should Be the Core Curriculum, Subgroups of Underperforming Learners, or Individual Struggling Students (T. Christ, 2008) – If less than 80% of students are successfully meeting academic or behavioral goals, the intervention focus is on the core curriculum and general student population. – If no more than 15% of students are not successful in meeting academic or behavioral goals, the intervention focus is on small-group ‘treatments’ or interventions. – If no more than 5% of students are not successful in meeting academic or behavioral goals, the intervention focus is on the individual student.

Response to Intervention Tier 1: What Are the Recommended Elements of ‘Core Curriculum’? : More Research Needed “In essence, we now have a good beginning on the evaluation of Tier 2 and 3 interventions, but no idea about what it will take to get the core curriculum to work at Tier 1. A complicating issue with this potential line of research is that many schools use multiple materials as their core program. ” p. 640 Source: Kovaleski, J. F. (2007).

Response to Intervention Limitations of Intervention Research… “…the list of evidence-based interventions is quite small relative to the need [of RTI]…. Thus, limited dissemination of interventions is likely to be a practical problem as individuals move forward in the application of RTI models in applied settings. ” p. 33 Source: Kratochwill, T.

Response to Intervention Schools Need to Review Tier 1 (Classroom) Interventions to Ensure That They Are Supported By Research There is a lack of agreement about what is meant by ‘scientifically validated’ classroom (Tier I) interventions. Districts should establish a ‘vetting’ process—criteria for judging whether a particular instructional or intervention approach should be considered empirically based.

Response to Intervention RTI & Intervention: Key Concepts www. interventioncentral. org

Response to Intervention Essential Elements of Any Academic or Behavioral Intervention (‘Treatment’) Strategy: • Method of delivery (‘Who or what delivers the treatment? ’) Examples include teachers, paraprofessionals, parents, volunteers, computers. • Treatment component (‘What makes the intervention effective? ’) Examples include activation of prior knowledge to help the student to make meaningful connections between ‘known’ and new material; guide practice (e. g. , Paired Reading) to increase reading fluency; www. interventioncentral. org periodic review of material to aid 9

Response to Intervention Core Instruction, Interventions, Accommodations & Modifications: Sorting Them Out • Core Instruction. Those instructional strategies that are used routinely with all students in a general-education setting are considered ‘core instruction’. Highquality instruction is essential and forms the foundation of RTI academic support. NOTE: While it is important to verify that good core instructional practices are in place for a struggling student, those routine practices do not ‘count’ as individual student interventions. www. interventioncentral. org 10

Response to Intervention Core Instruction, Interventions, Accommodations & Modifications: Sorting Them Out • Intervention. An academic intervention is a strategy used to teach a new skill, build fluency in a skill, or encourage a child to apply an existing skill to new situations or settings. An intervention can be thought of as “a set of actions that, when taken, have demonstrated ability to change a fixed educational trajectory” (Methe & Riley-Tillman, 2008; p. 37). www. interventioncentral. org 11

Response to Intervention Core Instruction, Interventions, Accommodations & Modifications: Sorting Them Out • Accommodation. An accommodation is intended to help the student to fully access and participate in the general-education curriculum without changing the instructional content and without reducing the student’s rate of learning (Skinner, Pappas & Davis, 2005). An accommodation is intended to remove barriers to learning while still expecting that students will master the same instructional content as their typical peers. – Accommodation example 1: Students are allowed to supplement silent reading of a novel by listening to the book on tape. – Accommodation example 2: For unmotivated students, the instructor breaks larger assignments into smaller ‘chunks’ and providing students with www. interventioncentral. org 12

Response to Intervention Core Instruction, Interventions, Accommodations & Modifications: Sorting Them Out • Modification. A modification changes the expectations of what a student is expected to know or do—typically by lowering the academic standards against which the student is to be evaluated. Examples of modifications: – Giving a student five math computation problems for practice instead of the 20 problems assigned to the rest of the class – Letting the student consult course notes during a test when peers are not permitted to do so www. interventioncentral. org – Allowing a student to select a much easier book for a 13

Response to Intervention Big Ideas: The Four Stages of Learning Can Be Summed Up in the ‘Instructional Hierarchy’ pp. 2 -3 (Haring et al. , 1978) Student learning can be thought of as a multi-stage process. The universal stages of learning include: • Acquisition: The student is just acquiring the skill. • Fluency: The student can perform the skill but must make that skill ‘automatic’. • Generalization: The student must perform the skill across situations or settings. • Adaptation: The student confronts novel task demands that require that the student adapt a current skill to meet new requirements.

Response to Intervention Increasing the Intensity of an Intervention: Key Dimensions Interventions can move up the RTI Tiers through being intensified across several dimensions, including: • • • Type of intervention strategy or materials used Student-teacher ratio Length of intervention sessions Frequency of intervention sessions Duration of the intervention period (e. g. , extending an intervention from 5 weeks to 10 weeks) • Motivation strategies Source: Burns, M.

Response to Intervention RTI Interventions: What If There is No Commercial Intervention Package or Program Available? “Although commercially prepared programs and the subsequent manuals and materials are inviting, they are not necessary. … A recent review of research suggests that interventions are research based and likely to be successful, if they are correctly targeted and provide explicit instruction in the skill, an appropriate level of challenge, sufficient opportunities to respond to and practice the skill, and immediate feedback on performance…Thus, these [elements] could be used which to judge potentialin tier 2 Source: Burns, as M.

Response to Intervention Research-Based Elements of Effective Academic Interventions • ‘Correctly targeted’: The intervention is appropriately matched to the student’s academic or behavioral needs. • ‘Explicit instruction’: Student skills have been broken down “into manageable and deliberately sequenced steps and providing overt strategies for students to learn and practice new skills” p. 1153 • ‘Appropriate level of challenge’: The student experiences adequate success with the instructional task. • ‘High opportunity to respond’: The student actively responds at a rate frequent enough to promote Source: effective Burns, M.

Response to Interventions: Potential ‘Fatal Flaws’ Any intervention must include 4 essential elements. The absence of any one of the elements would be considered a ‘fatal flaw’ (Witt, Van. Der. Heyden & Gilbertson, 2004) that blocks the school from drawing meaningful conclusions from the student’s response to the intervention: 1. Clearly defined problem. The student’s target concern is stated in specific, observable, measureable terms. This ‘problem identification statement’ is the most important step of the problem-solving model (Bergan, 1995), as a clearly defined problem allows the teacher or RTI Team to select a wellmatched intervention to address it. 2. Baseline data. The teacher or RTI Team measures the student’s academic skills in the target concern (e. g. , reading fluency, math computation) prior to beginning the intervention. Baseline data becomes the point of comparison throughout the intervention to help the school to determine whether that intervention is effective. 3. Performance goal. The teacher or RTI Team sets a specific, data-based goal for student improvement during the intervention and a checkpoint date by which the goal should be attained. 4. Progress-monitoring plan. The teacher or RTI Team collects student data Source: Witt, to J. C. , Van. Der. Heyden, A. M. , &the Gilbertson, D. (2004).

Response to Intervention Math Intervention Planning: Some Challenges for Elementary RTI Teams • There is no national consensus about what math instruction should look like in elementary schools • Schools may not have consistent expectations for the ‘best practice’ math instruction strategies that teachers should routinely use in the classroom • Schools may not have a full range of assessment methods to collect baseline and progress monitoring data on math difficulties www. interventioncentral. org 26

Response to Intervention 1. Profile of Students With Significant Math Difficulties Spatial organization. The student commits errors such as misaligning numbers in columns in a multiplication problem or confusing directionality in a subtraction problem (and subtracting the original number—minuend— from the figure to be subtracted (subtrahend). 2. Visual detail. The student misreads a mathematical sign or leaves out a decimal or dollar sign in the answer. 3. Procedural errors. The student skips or adds a step in a computation sequence. Or the student misapplies a learned rule from one arithmetic procedure when completing another, different arithmetic procedure. 4. Inability to ‘shift psychological set’. The student does not shift from one operation type (e. g. , addition) to another (e. g. , multiplication) when warranted. 5. Graphomotor. The student’s poor handwriting can cause him or her to misread handwritten numbers, leading to errors in computation. 6. Memory. The student fails to remember a specific math fact needed to solve a problem. (The student may KNOW the math fact but not be able to recall it at ‘point of performance’. ) 7. Judgment and reasoning.

Children who exhibit mathematics difficulties include those performing in the low average range (e. g. , at or below the 35 th percentile) as well as those performing well below average…Using higher percentile cutoffs increases the likelihood that young children who go on to have serious math problems will be picked up in the screening. ” p. 295 Source: Gersten, R. , Jordan, N.

Response to Intervention Profile of Students with Math Difficulties (Kroesbergen & Van Luit, 2003) [Although the group of students with difficulties in learning math is very heterogeneous], in general, these students have memory deficits leading to difficulties in the acquisition and remembering of math knowledge. Moreover, they often show inadequate use of strategies for solving math tasks, caused by problems with the acquisition and the application of both cognitive and metacognitive strategies. Because of these problems, they also show deficits in generalization and. Mathematics transfer of for children with special Source: Kroesbergen, E. , & Van Luit, J. E. H.

Response to Intervention Three General Levels of Math Skill Development (Kroesbergen & Van Luit, 2003) As students move from lower to higher grades, they move through levels of acquisition of math skills, to include: • Number sense • Basic math operations (i. e. , addition, subtraction, multiplication, division) • Problem-solving skills: “The solution of both verbal and nonverbal problems through the application of previously acquired information” (Kroesbergen & Van Luit, 2003, p. 98) Source: Kroesbergen, E. , & Van Luit, J.

Response to Intervention Development of ‘Number Sense’ www. interventioncentral. org

Response to Intervention What is ‘Number Sense’? (Clarke & Shinn, 2004) “… the ability to understand the meaning of numbers and define different relationships among numbers. Children with number sense can recognize the relative size of numbers, use referents for measuring objects and events, and think and work with numbers in a flexible manner that treats numbers as a sensible system. ” p. 236 Source: Clarke, B. , & Shinn, M.

Response to Intervention What Are Stages of ‘Number Sense’? (Berch, 2005, p. 336) 1. Innate Number Sense. Children appear to possess ‘hard-wired’ ability (neurological ‘foundation structures’) to acquire number sense. Children’s innate capabilities appear also to include the ability to ‘represent general amounts’, not specific quantities. This innate number sense seems to be characterized by skills at estimation (‘approximate numerical judgments’) and a counting system that can be described loosely as ‘ 1, 2, 3, 4, … a lot’. 2. Acquired Number Sense. Young students learn through indirect and direct instruction to count specific objects beyond four and to internalize a number line as a mental representation of those Source: Berch, D. B. (2005).

Response to Intervention Task Analysis of Number Sense & Operations (Methe & Riley-Tillman, 2008) “Knowing the fundamental subject matter of early mathematics is critical, given the relatively young stage of its development and application…, as well as the large numbers of students at risk for failure in mathematics. Evidence from the Early Childhood Longitudinal Study confirms the Matthew effect phenomenon, where students with early skills continue to prosper over the course of their education while children who struggle at kindergarten entry tend to experience great degrees of problems in mathematics. Given that assessment is the core of effective problem solving in foundational subject matter, much less is known about the specific building blocks and pinpoint subskills that lead to a numeric literacy, early numeracy, or number sense…” p. 30 Source: Methe, S.

Response to Intervention Children’s Understanding of Counting Rules The development of children’s counting ability depends upon the development of: • One-to-one correspondence: “one and only one word tag, e. g. , ‘one, ’ ‘two, ’ is assigned to each counted object”. • Stable order: “the order of the word tags must be invariant across counted sets”. • Cardinality: “the value of the final word tag represents the quantity of items in the counted set”. • Abstraction: “objects of any kind can be collected together and counted”. • Order irrelevance: “items within a given set can be tagged in any sequence”.

Response to Intervention Big Ideas: Learn Unit (Heward, 1996) The three essential elements of effective student learning include: 1. Academic Opportunity to Respond. The student is presented with a meaningful opportunity to respond to an academic task. A question posed by the teacher, a math word problem, and a spelling item on an educational computer ‘Word Gobbler’ game could all be considered academic opportunities to respond. 2. Active Student Response. The student answers the item, solves the problem presented, or completes the academic task. Answering the teacher’s question, computing the answer to a math word problem (and showing all work), and typing in the correct spelling of an item when playing an educational computer game are all examples of active student responding. 3. Performance Feedback. The student receives timely feedback about whether his or her response is correct—often with praise and encouragement. A teacher exclaiming ‘Right!

Response to Intervention Math Computation: Motivate With ‘Errorless Learning’ Worksheets In this version of an ‘errorless learning’ approach, the student is directed to complete math facts as quickly as possible. If the student comes to a number problem that he or she cannot solve, the student is encouraged to locate the problem and its correct answer in the key at the top of the page and write it in. Such speed drills build computational fluency while promoting students’ ability to visualize and to use a mental number line. TIP: Consider turning this activity into a ‘speed drill’. The student is given a kitchen timer and instructed to set the timer for a predetermined span of time (e. g. , 2 minutes) for each drill. The student completes as many problems as possible before the timer rings. The student then Source: Caron, T. A. (2007). Learning multiplication the easy way.

Response to Intervention Math Computation: Two Ideas to Jump-Start Active Academic Responding Here are two ideas to accomplish increased academic responding on math tasks. • Break longer assignments into shorter assignments with performance feedback given after each shorter ‘chunk’ (e. g. , break a 20 -minute math computation worksheet task into 3 seven-minute assignments). Breaking longer assignments into briefer segments also allows the teacher to praise struggling students more frequently for work completion and effort, providing an additional ‘natural’ reinforcer. • Allow students to respond to easier practice items orally rather than in written form to speed up the rate of correct responses.

Response to Intervention Math Computation: Problem Interspersal Technique • The teacher first identifies the range of ‘challenging’ problem-types (number problems appropriately matched to the student’s current instructional level) that are to appear on the worksheet. • Then the teacher creates a series of ‘easy’ problems that the students can complete very quickly (e. g. , adding or subtracting two 1 -digit numbers). The teacher next prepares a series of student math computation worksheets with ‘easy’ computation problems interspersed at a fixed rate among the ‘challenging’ problems. • If the student is expected to complete the worksheet independently, ‘challenging’ and ‘easy’ problems should be interspersed at a 1: 1 ratio (that is, every ‘challenging’ problem in the worksheet is preceded and/or followed by an ‘easy’ problem). • If the student is to have the problems read aloud and then.

Response to Intervention Comprehending Math Vocabulary: The Barrier of Abstraction “…when it comes to abstract mathematical concepts, words describe activities or relationships that often lack a visual counterpart. Yet studies show that children grasp the idea of quantity, as well as other relational concepts, from a very early age….

Response to Intervention Math Vocabulary: Classroom (Tier I) Recommendations • Preteach math vocabulary. Math vocabulary provides students with the language tools to grasp abstract mathematical concepts and to explain their own reasoning. Therefore, do not wait to teach that vocabulary only at ‘point of use’. Instead, preview relevant math vocabulary as a regular a part of the ‘background’ information that students receive in preparation to learn new math concepts or operations. • Model the relevant vocabulary when new concepts are taught. Strengthen students’ grasp of new vocabulary by reviewing a number of math problems with the class, each time consistently and explicitly modeling the use of appropriate vocabulary to describe the concepts being taught. Then have students engage in cooperative learning or individual practice activities in which they too must successfully use the new vocabulary—while the teacher provides targeted support to students as needed.

Response to Intervention Vocabulary: Why This Instructional Goal is Important As vocabulary terms become more specialized in content area courses, students are less able to derive the meaning of unfamiliar words from context alone. Students must instead learn vocabulary through more direct means, including having opportunities to explicitly memorize words and their definitions. Students may require 12 to 17 meaningful exposures to a word to learn it. www. interventioncentral. org 70

Response to Intervention Promoting Math Vocabulary: Other Guidelines – – – Create a standard list of math vocabulary for each grade level (elementary) or course/subject area (for example, geometry). Periodically check students’ mastery of math vocabulary (e. g. , through quizzes, math journals, guided discussion, etc. ). Assist students in learning new math vocabulary by first assessing their previous knowledge of vocabulary terms (e. g. , protractor; product) and then using that past knowledge to build an understanding of the term. For particular assignments, have students identify math vocabulary that they don’t understand. In a cooperative learning activity, have students discuss the terms. Then review any remaining vocabulary questions with the entire class. Encourage students to use a math dictionary in their vocabulary Source: Adams, T. L. work. (2003).

Response to Intervention Math Instruction: Unlock the Thoughts of Reluctant Students Through Class Journaling Students can effectively clarify their knowledge of math concepts and problem-solving strategies through regular use of class ‘math journals’. • At the start of the year, the teacher introduces the journaling weekly assignment in which students respond to teacher questions. • At first, the teacher presents ‘safe’ questions that tap into the students’ opinions and attitudes about mathematics (e. g. , ‘How important do you think it is nowadays for cashiers in fast-food restaurants to be able to calculate in their head the amount of change to give a customer? ”). As students become comfortable with the journaling activity, the teacher starts to pose questions about the students’ own mathematical thinking relating to specific assignments. Students are encouraged to use numerals, mathematical symbols, and diagrams in their journal entries to enhance their explanations. • The teacher provides brief written comments on individual student entries, as well as periodic oral feedback and encouragement to the entire class. • Teachers will find that journal entries are a concrete method for monitoring student understanding of more abstract math concepts.

Response to Intervention Teaching Math Symbols www. interventioncentral. org

Response to Intervention Learning Math Symbols: 3 Card Games 1. The interventionist writes math symbols that the student is to learn on index cards. The names of those math symbols are written on separate cards. The cards can then be used for students to play matching games or to attempt to draw cards to get a pair. 2. Create a card deck containing math symbols or their word equivalents. Students take turns drawing cards from the deck. If they can use the symbol/word on the selected card to generate a correct ‘mathematical sentence’, the student wins the card. For example, if the student draws a card with the term ‘negative number’ and says that “A negative number is a real number that is less than 0”, the student wins the card. 3.

Response to Intervention Elementary Students’ Use of Metacognitive Strategies In one study (Lucangeli & Cornoldi, 1997), students could be reliably sorted by math ability according to their ability to apply the following 4 -step metacognitive process to math problems: 1. Prediction. The student predicts before completing the problem whether he or she expects to answer it correctly. 2. Planning. The student specifies operations to be carried out in the problem and in what sequence. 3. Monitoring. The student describes the strategies actually used to solve the problem and to check the work. 4. Evaluation. The student judges whether, in his or her opinion, the problem has been correctly completed—and the degree of certitude backing that judgment. Use of metacognitive strategies was found to a better predictor of student success on higher-level problemsolving math tasks than on computational problems. Also, use of such strategies for computation problems dropped as students developed automaticity in those computation Source: Lucangeli, D. , & Cornoldi, C. (1997).

Response to Intervention ‘Mindful Math’: Applying a Simple Heuristic to Applied Problems By following an efficient 4 -step plan, students can consistently perform better on applied math problems. • UNDERSTAND THE PROBLEM. To fully grasp the problem, the student may restate the problem in his or her own words, note key information, and identify missing information. • DEVISE A PLAN. In mapping out a strategy to solve the problem, the student may make a table, draw a diagram, or translate the verbal problem into an equation. • CARRY OUT THE PLAN. The student implements the steps in the plan, showing work and checking work for each step. • LOOK BACK. The student checks the results.
