Alternative Cognitive Devices and the Lack of Development of Higher Order Thinking Skills Developmentally Appropriate Technology Acquisition Western Oregon University November 12, 2009 by Robert E. Mahoney
Background Verbal Math • High School Students unable to perform simple tasks • Excessive misuse of homophones There, They’re, and Their You’re and Your Even non-homophones such as Then and Than
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
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
Out with the Old, In with the New? • Educational Testing Service • Information & Communications Technology Skills test The New Standard
Question arises • What is so different in the last 20 years? Alternative Cognitive Devices What is happening?
Alternative Cognitive Devices • The user “outsources” the cognitive task • Calculators • Spell-Check • Predictive Spelling Alternative Cognitive Devices
Flynn Effect Phenotypic and Genotypic Intelligence Technology & Cognition
Flynn Effect • James R. Flynn • Rise in intelligence test scores over time • Requires re-norming Flynn Effect
Gains in IQ Ancestor Paradox Flynn Effect
Ancestor Paradox IQ • Ancestor’s IQ • Functioned in society • Societal Change • From Concrete to Abstract IQ IQ 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? Flynn Effect
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-norm Pre Re-norm 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 Flynn Effect
Technology & Cognition • Historically linked • Switch from oral to written • Negative and positive consequences • Rewriting neural networks (Small, 2008) Technology & Cognition
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
Declarative vs. Procedural Knowledge x2 + 11x + 28 7 + 4 7 · 4 (x + 7) (x + 4) Technology & Cognition
Genotypic vs. Phenotypic Intelligence • Genotypic Intelligence • Attributable to genetic causes • Phenotypic Intelligence • That which is exhibited • Genetics and the overlay of environmental factors Intelligence – Genes & Environment
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
Genotypic vs. Phenotypic Intelligence Flynn Effect Environmental factors no longer contribute to IQ gains Genotypic Intelligence Phenotypic Intelligence caused by the overlay of environmental factors raises IQ Intelligence – Genes & Environment
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
Reversal of the Flynn Effect • 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
Reversal of the Flynn EffectUnited States • SAT Scores • Decline in Textbook Difficulty (Hayes, et al., 1996) • National Assessment of Educational Progress (NAEP) Reversal of the Flynn Effect
NAEP Math Scores, 17-year-olds Note the lack of significant progress since 1992 Reversal of the Flynn Effect

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
Conclusion Alternative Cognitive Devices are likely significant environmental factors in the reduction of measures of intelligence, knowledge, and learning
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
