Western Oregon University November 12, 2009 by Robert E. Mahoney Alternative Cognitive Devices and the Lack of Development of Higher Order Thinking Skills Developmentally Appropriate Technology Acquisition
2
Background High School Students unable to perform simple tasks Excessive misuse of homophones MathVerbal There, They’re, and Their You’re and Your Even non-homophones such as Then and Than
3
Reports from Others Decline in SAT scores Is Google Making Us Stupid ? Employers noting lack of skills –United States (Cocodia, et al, 2003) –Britain (Phillips, 2007) 35% of college teachers note lack of readiness (Bauerlein, 2008) Indicators of Decline in Achievement
4
Government Documents Reading at Risk: A Survey of Literacy Reading in America (Bradshaw & Nichols, 2004) National Assessment of Educational Progress (NAEP) Indicators of Decline in Achievement
5
Out with the Old, In with the New? Educational Testing Service –Information & Communications Technology Skills test The New Standard
6
Question arises What is so different in the last 20 years? What is happening? Alternative Cognitive Devices
7
The user “outsources” the cognitive task –Calculators –Spell-Check –Predictive Spelling Alternative Cognitive Devices
8
Analysis of the Effects of Alternative Cognitive Devices Flynn Effect Technology & Cognition Phenotypic/Genotypic Intelligence Declines in Measures of Intelligence Temporal Comparison
9
Flynn Effect Phenotypic and Genotypic Intelligence Technology & Cognition
10
Flynn Effect James R. Flynn Rise in intelligence test scores over time Requires re-norming Flynn Effect
11
Gains in IQ Ancestor Paradox
12
Flynn Effect Ancestor Paradox Ancestor’s IQ Functioned in society Societal Change –From Concrete to Abstract IQ
13
Flynn Effect Gains in IQ 3 Percentage points per decade (average) Occurred until 1990s when it stopped or reversed in many developed countries (Teasdale & Owen, 2005) Why?
14
Types of Intelligence Greatest gains on fluid intelligence –Inherent reasoning Crystallized intelligence –What you have learned –Gains not as great Flynn Effect
15
Why are any Changes Significant? Education Legal System –Executions (Kanaya, et al, 2003) –Walker vs. True Social Security Mentally Impaired Classification per 1000 students, 1947-1999 (Flynn) Post Re-normPre Re-norm
16
Flynn Effect Commonly Cited Reasons for the Flynn Effect Genetics insufficient to account for change Change in Body size/Brain size (Storfer,1999) More liberal attitude (Brand, 1987) Nutrition Technological changes
17
Technology & Cognition Historically linked –Switch from oral to written Negative and positive consequences Rewriting neural networks (Small, 2008)
18
Declarative vs. Procedural Knowledge What if one lacks the neural network? What if one lacks the declarative knowledge? Procedural knowledge specifies how to bring declarative knowledge to bear in problem solving (Anderson, 1997) Over-reliance on the technology Technology & Cognition
19
Declarative vs. Procedural Knowledge x 2 + 11x + 28 Technology & Cognition 7 + 47 · 4 (x + 7) (x + 4)
20
Genotypic vs. Phenotypic Intelligence Genotypic Intelligence –Attributable to genetic causes Intelligence – Genes & Environment Phenotypic Intelligence –That which is exhibited Genetics and the overlay of environmental factors
21
Genotypic vs. Phenotypic Intelligence Genotypic Intelligence Decline –Based upon birth rate differential Caused by a societal imbalance –Lack of equal access to contraceptives and reproductive choices Fertility Rate (Number of Children per Family) Intelligence – Genes & Environment
22
Genotypic vs. Phenotypic Intelligence Genotypic Intelligence Phenotypic Intelligence caused by the overlay of environmental factors raises IQ Flynn Effect Environmental factors no longer contribute to IQ gains Intelligence – Genes & Environment
23
Reversal of the Flynn Effect Are we at the juncture wherein technology now interferes as an environmental factor thereby reducing measures of intelligence, knowledge, and learning? Reversal of the Flynn Effect
24
Denmark (Teasdale & Owen, 2005) Norway (Sundet, et al, 2004) Sweden (Emmanuelsson, et al, 1993) Britain (Ginsburg & Coe, 2007; Shayer, 2008) Australia (Cotton, 2005) Not reversing in developing countries Reversal of the Flynn Effect
25
Reversal of the Flynn Effect United States SAT Scores Decline in Textbook Difficulty (Hayes, et al., 1996) National Assessment of Educational Progress (NAEP) Reversal of the Flynn Effect
26
NAEP Math Scores, 17-year-olds Note the lack of significant progress since 1992 Reversal of the Flynn Effect
28
48.3 42.5 59.7 78.4 Not Allowed Calculators (Percent Correct) 77.1 87.9 89.2 87.0 Allowed Calculators (Percent Correct) Division Multiplication Subtraction Addition MATH SKILL NAEP 1999 Math Test Data Division Multiplication Subtraction Addition MATH SKILL 77.1 87.9 89.2 87.0 Allowed Calculators (Percent Correct) 48.3 42.5 59.7 78.4 Not Allowed Calculators (Percent Correct) Reversal of the Flynn Effect
29
What Conclusion? It is erroneous to conclude that calculators are beneficial to understanding math Students only show the computational proficiency with an assistive device Reversal of the Flynn Effect
33
Conclusion Alternative Cognitive Devices are likely significant environmental factors in the reduction of measures of intelligence, knowledge, and learning
34
Change in Rate of Flynn Effect Alternative Cognitive Devices Reduce Declarative Knowledge Reduce Procedural Knowledge Reduce Higher Order Thinking Skills Reduce Phenotypic Intelligence Reduce Measures of IQ, Knowledge and Learning Genotypic Intelligence Proposed Mechanism
35
Limitations Research limited by lack of matching dates for test data vs. census data –Lack of correlation coefficient –Need for additional data in this area Universal Presence of Alternative Cognitive Devices –In developed countries –Limits controlled studies
36
Additional Research The need for additional research in this area exists –Societal significance Likely source for additional research would be developing countries –Alternative Cognitive Devices not as prevalent
37
“Skill obtained apart from the thinking is not connected with any sense of the purposes for which it is to be used.” ~John Dewey, 1916 93 Year Old Observation
38
Discussion Do you believe that technology is resulting in a reduction of higher order thinking skills? Open Discussion
39
Developmentally Appropriate Technology Acquisition Is this concept key to incorporating technology into education? Open Discussion
