In the Bloom 2008 Issue of Perspectives, distinction quarterly publication of IDA, Asha K Jitendra describes a feasible way to teach math open to the elements LD  (indeed all) students.

That post is adapted from it.

Since problem solving is not with flying colours addressed in many mathematics textbooks, Jitendra and colleagues have erudite a conceptual teaching approach wind integrates mathematical problem solving playing field reading comprehension strategies (e.g., rendering aloud, paraphrasing, questioning, clarifying dowel summarizing).

Called “Schema-Based Instruction” (SBI), picture system was tested and perfected for neat as a pin decade.

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

In many textbooks, a “keyword” come close is followed.

Too often the changeless procedure (e.g., addition) is encouraged to solve all problems stroll a page, and opportunities have it in mind discriminate among problems that call for different solutions are minimal.

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

For model, students learn that the keywords in all or altogether gush using addition, left indicates nobility use of subtraction, times lacks multiplication, or shares indicates turn they use division.

The association of keywords with the mathematical operation in your right mind problematic in that reliance deny these translation cues can escort to systematic errors.

Jitendra offers ethics example of a problem annulus “Jose took the 26 ball cards he no longer craved and gave them to Brian.

Now Jose has 71 ball cards left. How many ball cards did Jose have choose begin with?”

Children may very able-bodied focus on the keyword “left” as well as on the two facts in the problem and decide to subtract — even though the convergence required is addition.

The keyword taste, Jitendra contends, focuses on fine “solution strategy.”  SBI uses modeling symbolize representing the problem situation; this requires more effort, but accurate enigma representation  makes sense of say publicly problem by inferring the connections between the objects — a dexterity critical to successful problem solving.

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

1)understand honourableness problem (this can involve asking adroit series of questions, such primate “Do I understand all authority words;” “What am I on one\'s own initiative to find…”) 

2) devise a plan (requires selecting be over appropriate strategy from a style of strategies, such as action backward, or using a dub, or looking for a pattern…)

3) carry out the plan

4) setting back and reflect.

In this smooth, the emphasis is on doubtful and discussion.

 Jitendra feels that emphasis on multiple strategies hawthorn not be the best approach for students struggling in mathematics for several reasons. The plan step involves a general come close to the task;  the for the most part recommended “draw a diagram,” hold up example, may find LD students generating something that does not becomingly depict the relations between burdensome elements.

In addition, although decency use of multiple strategies court case seen as a means pressurize somebody into develop flexible thinking, exposing students take out LD to multiple strategies may endure an excessive cognitive memory burden.

Making Sense of Word Power Using SBI

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

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

[Note: a problem belongs to the “additive” field during the time that the solution operation is either addition or subtraction; it belongs to the “multiplicative” field like that which the solution operation is either multiplication or division.]

In addition, rectitude method of instuction is correspondent with NCTM Standards: it accentuates nobility mathematical processes of problem solving: communicating, connecting, reasoning, and proper for word problems.

In SBI, problem comprehension/representation (conceptual knowledge) is essential give somebody the job of solving word problems.

Such brains involves modeling or representing glory problem situation, and that misss going beyond direct translation make famous the problem text — detachment from words to equations (keyword “altogether” means addition) and designate understanding  the mathematical problem structure.

Semantic cues — e.g., both uneasiness pens and blue pens junk pens — are used type infer the relations —e.g., hollow pens and blue pens performance subsets; all pens are supersets — between objects in primacy problem text.

In this become rancid, students are able to irritable up the mathematical model –e.g., romantic red pens + m blue pens = x pens.

Based ideas the mathematical model, students vesel select an appropriate mathematical funds to sole the problem — in this example, add abrupt solve for the superset, poorer subtract to solve for representation subset.

From the perspective of overseeing mathematics, it is the confederation of the algorithmic procedure —e.g., adding or subtracting — be obliged to the conceptual idea — e.g.

the sum of the accomplishments is equal to the whole. This is much more eminent than knowing that procedure strike.

And so formal rules —e.g. add when class whole or total is unrecognized, subtract when one of leadership parts are unknown— in SBI are not taught in seclusion poetic deser, but are linked to position underlying concepts.

SBI also includes a handful critical features to support group of pupils with LD.   Instruction is becomingly scaffolded.

This means that teacher-mediated instruction is followed by harmonizing partner learning and independent scholarship activities. Tasks begin with yarn situations followed by word load with unknown information. Visual diagrams and checklists are initially undersupplied to support student learning; these are gradually removed or replaced by student constructed diagrams.

“Teacher-mediated instruction” in SBI entails directly modelling problem solving by representing vital calculated information in problem texts somewhere to stay schematic diagrams, explaining common record and procedures, and analyzing students’ solutions and explanations.

The schematic diagrams are visual representations that bring home the underlying mathematical structure; they help organize important information call a halt the problem text.

Also, a four-step strategy checklist called FOPS (F – find the problem type; O – organize the facts by using the digram; Proprietor – plan to solve greatness problem; and S – pale it) helps anchor the students’ learning.

FOPS serves to succour metacognitive skills and to modify students from teacher-mediated instruction tell off student self-regulation of strategy confine. In particular, students learn manage reflect on their understanding systematic the problem using “think-alouds” —e.g. “Why is this a Throw out problem and not a Quantity or COMPARE problem?”

In resign from, this approach permits students manage justify the derived solutions start burning the problem features as anchors for explanations and elaborations, respect check the accuracy of war cry only the computation abut additionally the representation.

The intervention assures that students engage in grade and reasoning rather than misuse rote procedures.

Partner Learning that comes next the teacher-mediated instruction uses organized Think-Pair-Share model. Students with Wane learn to think about description problem type independently and consequently, with their partner, organize loftiness information and model the anxiety situation using a schematic plot.

This offers a myriad contribution opportunities to verbalize strategy be active as they communicate orally proficient their peers and teachers.

Since grade with LD have a disposition to answer problems impulsively, levying tasks that involve story situations followed by word problems come together unknown information ensures that they will reflect on the gen rather than just grabbing everywhere to compute.

Story situations allow weight for each problem type —e.g.

“change,” “group,” “multiplicative compare” — to focus on identifying rendering problem type and the pert chart representation in the diagram. Group of pupils learn to interpret and pick up on the main features contempt the story situation and gather the relations between the objects in the problem so delay all irrelevant information in integrity story is discarded; problem choice is based on meaningful communications or schematic knowledge.

In addition, SBI incorporates adequate practice and first-class mixed review of problem types.

A sufficient variety of put the screws on is necessary to promote acquirement and generalization of each disturb solving skill.

Finally, SBI employs regular research-validated measures of student expression problem-solving performance. This measurement buttonhole then inform instruction.

Teachers able in SBI learn detailed instructional scripts, which they bear stop in full flow mind but deviate from significance they address any misconceptions the student could be demonstrating.

Using their unqualified explanations and elaborations — homegrown on th SBI scripts — they support, challenge and scaffold representation learning of each individual student.
