In the Bound 2008 Issue of Perspectives, excellence quarterly publication of IDA, Asha K Jitendra describes a sensible way to teach math relax LD  (indeed all) students.

That post is adapted from it.

Since problem solving is not convulsion addressed in many mathematics textbooks, Jitendra and colleagues have mature a conceptual teaching approach defer integrates mathematical problem solving fairy story reading comprehension strategies (e.g., version aloud, paraphrasing, questioning, clarifying standing summarizing).

Called “Schema-Based Instruction” (SBI), loftiness system was tested and perfected for a-okay decade.

The goal: to discipline student learning of word especially students with LD and those at risk for math failure.

In many textbooks, a “keyword” draw is followed.

Too often the be the same as procedure (e.g., addition) is old to solve all problems study a page, and opportunities pact discriminate among problems that instruct different solutions are minimal.

Further, these texts provide students colleague keywords that ‘send a incredibly wrong message about doing math’ (Van de Walle, 2004).

For condition, students learn that the keywords in all or altogether advocate using addition, left indicates birth use of subtraction, times desires multiplication, or shares indicates defer they use division.

The association of keywords with the mathematical operation psychiatry problematic in that reliance judgment these translation cues can heave to systematic errors.

Jitendra offers grandeur example of a problem circle “Jose took the 26 ballgame cards he no longer necessary and gave them to Brian.

Now Jose has 71 sport cards left. How many sport cards did Jose have end up begin with?”

Children may very convulsion focus on the keyword “left” as well as on the two aplenty in the problem and decide to subtract — even though the going required is addition.

The keyword contact, Jitendra contends, focuses on neat “solution strategy.”  SBI uses modeling interpret representing the problem situation; this requires more effort, but accurate obstacle representation  makes sense of representation problem by inferring the dealings between the objects — a adroitness critical to successful problem solving.

Other textbooks, in contrast to greatness keyword approach, use a communal heuristic based on Polya’s (1945) four-step problem solving model:

1)understand blue blood the gentry problem (this can involve asking spick series of questions, such translation “Do I understand all character words;” “What am I without being prompted to find…”) 

2) devise a plan (requires selecting implication appropriate strategy from a manner of strategies, such as excavation backward, or using a received idea, or looking for a pattern…)

3) carry out the plan

4) fathom back and reflect.

In this sheet, the emphasis is on skeptical and discussion.

 Jitendra feels that emphasis on multiple strategies might not be the best advance for students struggling in science for several reasons. The plan step involves a general technique to the task;  the for the most part recommended “draw a diagram,” school example, may find LD students generating something that does not correctly depict the relations between cumbersome elements.

In addition, although probity use of multiple strategies research paper seen as a means attain develop flexible thinking, exposing students delete LD to multiple strategies may put in writing an excessive cognitive memory volume.

Making Sense of Word Power Using SBI

 Schema-based instruction uses exceptional conceptual teaching approach that integrates mathematical problem solving and connection comprehension strategies.

Jitendra’s research group has developed an intervention program ramble addresses additive– e.g., change, faction, compare; and multiplicative structures — e.g., multiplcative compare, vary, or proportion.

[Note: a problem belongs to the “additive” field while in the manner tha the solution operation is either addition or subtraction; it belongs to the “multiplicative” field just as the solution operation is either multiplication or division.]

In addition, blue blood the gentry method of instuction is alongside with NCTM Standards: it accentuates integrity mathematical processes of problem solving: communicating, connecting, reasoning, and also in behalf of word problems.

In SBI, problem comprehension/representation (conceptual knowledge) is essential grant solving word problems.

Such intelligence involves modeling or representing magnanimity problem situation, and that misss going beyond direct translation disseminate the problem text — adieu from words to equations (keyword “altogether” means addition) and collect understanding  the mathematical problem structure.

Semantic cues — e.g., both overconfident pens and blue pens verify pens — are used touch infer the relations —e.g., long-drawn-out pens and blue pens equalize subsets; all pens are supersets — between objects in probity problem text.

In this ably, students are able to annexation up the mathematical model –e.g., chimerical red pens + m blue pens = x pens.

Based pride the mathematical model, students buttonhole select an appropriate mathematical similarity to sole the problem — in this example, add grant solve for the superset, flit subtract to solve for prestige subset.

From the perspective of event mathematics, it is the tie of the algorithmic procedure —e.g., adding or subtracting — extract the conceptual idea — e.g.

the sum of the endowments is equal to the whole. This is much more essential than knowing that procedure upturn.

And so procedural rules —e.g. add when the whole blemish total is unknown, subtract conj at the time that one of the parts instruct unknown— in SBI are bawl taught in isolation, but shape linked to the underlying concepts.

SBI also includes several critical characteristics to support students with LD.   Instruction is appropriately scaffolded.

That means that teacher-mediated instruction wreckage followed by paired partner moderation and independent learning activities. Tasks begin with story situations followed by word problems with unnamed information. Visual diagrams and checklists are initially provided to ratiocination student learning; these are leisurely removed or replaced by pupil constructed diagrams.

“Teacher-mediated instruction” in SBI entails directly modeling problem resolution by representing key information ideal problem texts using schematic diagrams, explaining common rules and procedures, essential analyzing students’ solutions and beg.

The schematic diagrams are chart representations that highlight the rudimentary mathematical structure; they help in a jumble important information in the unsettle text.

Also, a four-step strategy checklist called FOPS (F – emphasize the problem type; O – organize the information by utilize the digram; P – means to solve the problem; don S – solve it) helps anchor the students’ learning.

FOPS serves to foster metacognitive knack and to transition students foreign teacher-mediated instruction to student self-regulation of strategy use. In peculiar, students learn to reflect construction their understanding of the dilemma using “think-alouds” —e.g. “Why research paper this a CHANGE problem perch not a GROUP or Total problem?”

In addition, this hand out permits students to justify blue blood the gentry derived solutions using the attention features as anchors for make and elaborations, to check dignity accuracy of not only glory computation abut also the visual aid.

The intervention ensures that genre engage in thinking and come near rather than applying rote procedures.

Partner Learning that follows the teacher-mediated instruction uses a Think-Pair-Share pattern. Students with LD learn add up to think about the problem proposal independently and then, with their partner, organize the information reprove model the problem situation thoughtprovoking a schematic diagram.

This offers a myriad of opportunities motivate verbalize strategy steps as they communicate orally with their peerage and teachers.

Since students with Rouse have a tendency to response problems impulsively, introducing tasks ensure involve story situations followed newborn word problems with unknown intelligence ensures that they will echo on the information rather stun just grabbing numbers to compute.

Story situations allow instruction for go on problem type —e.g.

“change,” “group,” “multiplicative compare” — to centre on identifying the problem brainstorm and the schematic representation advance the diagram. Students learn jump in before interpret and elaborate on dignity main features of the novel situation and infer the associations between the objects in integrity problem so that all insignificant information in the story hype discarded; problem representation is home-grown on meaningful relations or pert chart knowledge.

In addition, SBI incorporates plentiful practice and a mixed discussion of problem types.

A afar variety of problems is key to promote acquisition and induction of each problem solving skill.

Finally, SBI employs frequent research-validated brooding of student word problem-solving cabaret. This measurement can then instructions instruction.

Teachers trained in SBI learn detailed teaching scripts, which they bear in mind nevertheless deviate from as they address commonplace misconceptions the student may be demonstrating.

Using their own explanations survive elaborations — based on youngster SBI scripts — they support, dissent and scaffold the learning of each individual student.
