Self-Regulation Strategies for Students With Learning Disabilities [feedly]

Self-regulation strategies

When a student with a learning disability struggles academically, it's logical to think that the issue is related to the student's deficit in a specific ability. And while that may be true, there might be more to it. Students with learning disabilities often encounter academic difficulties, at least in part, because they don't have effective strategies for working through challenges.

One effective tool that students can use to improve academic performance, regardless of ability, is self-regulation. Self-regulation is the process by which students take charge of their own learning, monitoring their behavior and progress and making adjustments along the way to get from idea to execution. It's the transformation of thought into purposeful action. Here are several strategies teachers can introduce for use in the classroom and at home:

Setting Goals

Goal setting is an important part of self-regulation and can be foundational to other self-regulation strategies. When used effectively, the process of goal setting gives students an opportunity to observe their own behavior and pinpoint areas for improvement. It helps students identify what they need to do, lets them see how they are progressing, and motivates them to act productively.

Students should set goals for themselves that are specific and challenging, but not too hard. A goal should be quickly attainable so students can experience a sense of accomplishment and move on to tackle the next one. For example, when two students are struggling with homework, each might need to set a different goal to see improvement. The first student might identify time management as a problem and decide to cut out a leisure activity in order to achieve the goal of completing homework before dinnertime each day that week. The second student might realize that he needs to bring his class notes home from school every day so he has the information he needs to achieve his goal of completing all of his homework assignments for the week.

Self-Monitoring

Students self-monitor by asking themselves whether they have engaged in a specific, desired behavior. Building on the goal-setting examples above, our students might ask themselves, Am I using my time in the right way to complete my homework by dinnertime?Or, Did I put all of my homework assignments in my backpack to take home?Students may find it helpful to self-monitor for behaviors like paying attention, staying on task, following strategy steps, and meeting performance expectations such as completing all homework problems or spelling 8 of 10 spelling words correctly.

Self-Instruction

Self-instruction is also sometimes called "self-talk" and is part of normal development for many younger children. It can also be quite powerful when used by students of any age to purposefully self-regulate and direct learning behavior. For example, a student who is struggling to comprehend a challenging text might think, I need to look up the definitions of these unfamiliar words and read this page again.

Students can use self-talk to remind themselves to focus their attention, to take positive steps when faced with difficulties, to reinforce positive behaviors, and more. Teachers can model effective self-talk, but should allow each student to create and use her own statements. A little advance planning can be helpful here. Coming up with the right phrase in the heat of the moment – when focus has been lost or frustrations are running high – is unlikely to help. But taking a little time to write out some useful statements before starting a new project or beginning a homework assignment can enable students get themselves out of a tight spot.

Self-Reinforcement

Self-reinforcement occurs when a student chooses a motivating reward and then awards it to himself when he achieves a milestone. Self-reinforcement can be used over shorter and longer timeframes and can tie into goals. Our student who has identified time-management as an issue, for example, might decide, I can go to the movies on Sunday because I finished all of my homework before dinnertime every night this week.

Self-reinforcement can also work well in the classroom. Teachers and students can select rewards together and teachers can let students know how to earn them. Once a student has met the criteria for a reward, she can award it to herself – say, by selecting a sticker for her journal after completing the day's writing assignment and getting her teacher's approval.

Purposeful Learning

Becoming a better self-regulator isn't a panacea for academic difficulties, but students with learning disabilities who learn effective self-regulation strategies will have some advantages. They will have tools in their toolbox that they can try out in a variety of situations before seeking outside help, or when help is not immediately available. They will understand how their behavior influences their results. And they will understand that their learning is a purposeful, active process in which they play the leading role.

Best of all, these self-regulation strategies can benefit all learners, not just those who are struggling. Why not give them a try?

Our pick of the best psychology and neuroscience links from the past week:

Why sports psychologists couldn't save Brazil's World Cup hopes
Angela Patmore argues that the Brazilian team were given flawed advice - they were encouraged to relax, rather than trained to increase their mental resilience.

Open message to the European Commission concerning the Human Brain Project
Nearly 600 neuroscientists have signed an open letter criticising the European Commission's ambitious €1 Billion Human Brain Project for being too narrow in its focus. The Project (which aims to create a computer simulation of the human brain) has published its official response as a pdf.

On the emptiness of failed replications
Many scholars have called for more emphasis and status to be given to replication attempts in psychology. Here, Harvard psychology professor Jason Mitchell argues that replication attempts are largely pointless. His essay has provoked several responses, including from Pete Etchells, Tom Stafford, and Neuroskeptic.

Babies' Minds
Listen again on BBC iPlayer as Claudia Hammond explores the latest research on infant cognition and brain development.

Beyond a joke: how to study laughter scientifically
Find out what happened when Sophie Scott asked a comedy audience to wear "special hats, [and] breath belts round their middles".

Praise them!
"Everyone thinks that too much praise can turn children into entitled monsters," says Carlin Flora, introducing her Aeon essay, "but the science isn't nearly that simple."

Blood test for Alzheimer's "no better than coin toss"
NHS Choices with a sober analysis of the research behind sensational media reports that said a new blood test could identify the start of dementia with high accuracy.

'Wisdom of the crowd': The myths and realities
Philip Ball summarises research that tells us when crowds are smart and when they're dumb. To boost group intelligence, he says, add new members who are as different as possible from the current set.

The Fault in Our DNA 
Science writer David Dobbs reviews Nicholas Wade's A Troublesome Inheritance:  "a deeply flawed, deceptive and dangerous book."

The Myth of the Alpha Male
Psychologist Scott Barry Kaufman explains there are two ways to commanding respect as a man: one is via dominance, the other is via prestige. And it's the latter, associated with altruism and kindness, that leads to long term popularity and success.

More support for the developmental cascade model (Gs, Gwm, Glr and Gf)

As readers of this blog know, I am partial to research that continues to support Fry and Hale's developmental cascade model, which indicates that processing speed (Gs) has a direct effect on working memory (Gwm/Gsm), which in turn has direct effect on fluid reasoning (Gf) or general intelligence (g). Gs influence is indirect--mediated by Gwm. Another study continues to support this model but adds the wrinkle of secondary memory (some Glr abilities), which also only has an indirect effect on Gf as mediated by Gwm.

The story behind Dr. IQ McGrew's infamous WJ III and WJ IV test easel signature




I was pleased to receive my WJ IV test battery last week (I am a coauthor--conflict of interest disclosure). I was surprised to see that the publisher had lifted the author signatures that were on a limited edition printing of the WJ III back in 2001. So there I was looking at my barely third grade level signature....again. It made me laugh.

Today I received an email (the second) commenting on my signature. I provided the story. The person (semi-serious or tonque-n-check) was relieved as they thought it showed signs of a sub-clinical tremor and the possibility of signs of emerging problems.

The real truth is a funny story (in retrospect). When I was in grade school I struggled with "penmanship." I hated it. We used the Palmer Method. Everyday we had to practice making repetitive, rhythmic shapes.....and it was hell for me. My fingers turned red and I pressed so damn hard. Couple that with some spelling problems, and if I had been a child in today's schools, I would likely have been diagnosed with a mild spelling disability and dysgraphia. It likely is genetic, as my 37 year old son's handwriting (if you can call it that) is even worse and shows all the same signs.

Fast forward to the original request to supply the publisher with my signature for the WJ III. I spent the good part of a morning trying to make the best possible signature using different pens, pencils and multiple pieces of paper. I ended up with two choices. One would be my adult signature, which is a wild K followed by a few squiggly lines, with a very crude M somewhere in the middle. It is a way to disguise my horrible penmanship. I sent the publisher a page with various versions of the two types (doing it slow and doing it fast) and simply told them to pick one. They picked the one that was my best effort, and I swear it would not be judged as being beyond third grade level work.

So...now my signature is back to haunt me.

The good news is that in high school I completed a typing course. And damn, I was the fastest male student in my large class and earned many of those small words-per-minute pins. It was not the coolest thing to brag about in high school. Then, when PC's became available  later, all my problems were over (except for my spelling issues--which I think are more due to a very "busy mind"---and can be handled by spell check--if I bother to do it). I can type at a very fast rate on a computer keyboard. Technology saved me. I tell people that typing was the most important class I completed in high school. I have fond memories of Mrs. Carpenter, my HS typing teacher at Moorhead High. She made a difference.

So...before the rumors start the I am in some form of neurocognitive decline, I wanted to share "the rest of the story."

Knowing what to measure, and how to measure it, can make a complicated world less so. There is nothing like the sheer power of numbers to scrub away layers of confusion and contradiction, especially with emotional, hot-button topics.

1. What Does It Mean to Think Like a Freak?

The fact is that solving problems is hard. If a given problem still exists, you can bet that a lot of people have already come along and failed to solve it. Easy problems evaporate; it is the hard ones that linger. Furthermore, it takes a lot of time to track down, organize, and analyze the data to answer even one small question well.

Gender differences in scholastic achievement: A meta-analysis. [feedly]



----
Gender differences in scholastic achievement: A meta-analysis.
// Psychological Bulletin - Vol 136, Iss 4

A female advantage in school marks is a common finding in education research, and it extends to most course subjects (e.g., language, math, science), unlike what is found on achievement tests. However, questions remain concerning the quantification of these gender differences and the identification of relevant moderator variables. The present meta-analysis answered these questions by examining studies that included an evaluation of gender differences in teacher-assigned school marks in elementary, junior/middle, or high school or at the university level (both undergraduate and graduate). The final analysis was based on 502 effect sizes drawn from 369 samples. A multilevel approach to meta-analysis was used to handle the presence of nonindependent effect sizes in the overall sample. This method was complemented with an examination of results in separate subject matters with a mixed-effects meta-analytic model. A small but significant female advantage (mean d = 0.225, 95% CI [0.201, 0.249]) was demonstrated for the overall sample of effect sizes. Noteworthy findings were that the female advantage was largest for language courses (mean d = 0.374, 95% CI [0.316, 0.432]) and smallest for math courses (mean d = 0.069, 95% CI [0.014, 0.124]). Source of marks, nationality, racial composition of samples, and gender composition of samples were significant moderators of effect sizes. Finally, results showed that the magnitude of the female advantage was not affected by year of publication, thereby contradicting claims of a recent "boy crisis" in school achievement. The present meta-analysis demonstrated the presence of a stable female advantage in school marks while also identifying critical moderators. Implications for future educational and psychological research are discussed. (PsycINFO Database Record (c) 2014 APA, all rights reserved)

Gc as higher order factor including other knowledge systems (verbal, Gq, Grw, Gkn, etc).

Interesting new study that provides some support for our (Schneider & McGrew, 2012 - largely the brilliance of Joel Schneider) conceptualization of Gc as a higher stratum factor, consistent with Cattell's provincial power gc, that includes language/verbal abilities, reading abilities (Grw), quantitative knowledge (Gq), domain-specific knowledge (Gkn), and possible other sources of knowledge. Our figure is at the end of this post. Click on images to enlarge.

The CHC Periodic Table of Cognitive Elements: "What are you made of?" Now available on a t-shirt

Back by popular demand, the blogmaster has created a new and improved CHC Theory Periodic Table of Human Cognitive Elements figure!  It is shown below.  Future updates will provide links to the updated definitions that go with each cognitive element code.  This new CHC periodic table represents the latest iteration of the CHC taxonomy of human cognitive abilities as summarized in the forthcoming WJ IV Technical Manual.

Even more exciting is that you can now purchase a t-shirt with the CHC Periodic Table printed on the front, with the title "The CHC Periodic Table:  What are you made of?"  You can find it here or go to the blog roll and click on IQs Corner Skreened blog badge.  More to come:)

Assessing the Flynn Effect in the Wechsler scales. [feedly]



----
Assessing the Flynn Effect in the Wechsler scales.
// Journal of Individual Differences - Vol 31, Iss 2

The current study examined the Flynn Effect (i.e., the increase in IQ scores over time) across all editions of the Wechsler Adult Intelligence Scale (WAIS), Wechsler Intelligence Scale for Children (WISC), and Wechsler Preschool and Primary Scale of Intelligence (WPPSI). By reverse engineering the correlation and scale score transformations from each Wechsler edition's technical manual, we made a mean and covariance matrix using the subtests and age groups that were in common for all editions of a given instrument. The results indicated that when aggregated, there was a FE of 0.44 IQ points/year. This Wechsler instrument used, however, moderates the FE, with the WISC showing the largest FE (0.73 IQ points/year) and the WAIS showing a smallest FE (0.30 IQ points/year). Moreover, this study found that the amount of invariant indicators across instruments and age groups varied substantially, ranging from 51.53% in the WISC for the 7-year-old group to 10.00% in the WPPSI for the 5- and 5.5-year-old age groups. Last, we discuss future direction for FE research based on these results. (PsycINFO Database Record (c) 2014 APA, all rights reserved)

Gs->working memory->Gf developmental-differential psych developmental cascade model

Very interesting research that suggests a developmental (neo-Piagetian) wrinkle to the developmental cascade model, a model that has shown that Gs influences working memory (Gwm), and working memory in turn influences Gf (but Gs has no direct influencee on Gf).
[Click on images to enlarge]

"However, the exact role of speed and working memory is still debated. Some researchers emphasize speed as a purer index of the quality of information processing in the brain (e.g., Jensen, 1998). This interpretation is based on studies which estimate the relation between speed and intelligence without involving working memory. Others emphasize working memory because it is the workspace of thinking (Kyllonen & Christal, 1990). Studies emphasizing working memory usually measure all three constructs in young adults, when working memory is the dominant predictor of Gf, according to the patterns to be described below. Finally, others assume a causal linear relation between them such that changes in speed cause changes (or differences) in working memory which, in turn, cause changes (or differences) in Gf (Case, 1985; Coyle, Pillow, Snyder, & Kochunov, 2011; Kail, 1991; Kail & Ferrer, 2007). However, this chain of relations may only reflect the fact that working memory tasks are both timed, like speed tasks, and require information management, like Gf tasks, rather than a causal sequence. In fact, there is evidence that control of attention is common to all, speed, WM, and Gf, explaining their relations (Cowan, Morey, Chen, & Bunting, 2007; Engle et al., 1999; Stankov & Roberts, 1997)"

Note. Attentional control (AC) is now proposed to represent a narrow ability under the broad CHC domain of Gwm (short-term working memory) by the authors of the forthcoming WJ IV [Conflict of interest disclosure--I am one of the coauthors of the WJ III and WJ IV). This is consistent with Schneider and McGrew's (2012) recent book chapter CHC model update.

"Demetriou et al. (2013) showed recently that the relations between these constructs are more complicated than originally assumed, because they vary with growth. Specifically, speed increases and WM expands. Gf evolves along a reconceptuali-zation sequence (ReConceP) where changes in the nature of representations alternate with changes in the command and interlinking of representations constructed earlier."

"These patterns provide support for an integrated developmental–differential theory of intelligence that would explicate why Gf changes coalesce with speed at the beginning of developmental cycles and with WM changes at the end. Gf undergoes three types of change: representational, inferential, and complexity."

I previously presented (McGrew, 2005) support for the developmental cascade model in 5 age-differentiated WJ III norm samples (see one of the sample models below). Instead of causal models with Gf as the criterion, I specified a criterion g-factor defined by Gv, Ga, Glr, Gf, and Gc. The results strongly supported the Gwm->g link, and significant causal links from Gs to working memory. Gs did not dispaly a direct link to g in the childhood samples, but did demonstrate small significant direct paths to g in the adolescent and adult samples.
