“Text is linear; it is black and white; it doesn't zoom around the page in 3-D; it isn't intelligent by itself; in fact, in terms of immediate reaction it is quite boring. I can't imagine a single preliterate was ever wowed at the first sight of text, and yet text has been the basis of arguably the most fundamental intellectual transformation of the human species. It and its subforms, such as algebra, have made science education for all a plausible goal.” FirstsHumansHas BeensMadeI CanFactsGoalBlackTermWhiteLearningImaginePagesIntellectualSightBasesTransformationIntelligentFundamentalsSpeciesBoringReactionsProgrammingBlack And WhiteComputer ProgrammingLinearProgramming LanguagesAlgebraPlausibleComputer LanguageHuman SpeciesEducation For AllZoomScience Education Author:Andrea diSessa

“In the development of the understanding of complex phenomena, the most powerful tool available to the human intellect is abstraction. Abstraction arises from the recognition of similarities between certain objects, situations, or processes in the real world and the decision to concentrate on these similarities and to ignore, for the time being, their differences.” WorldHumansRealCertainProcessUnderstandingDifferencesDecisionPowerfulSituationLearningObjectsDevelopmentToolsComplexesAvailableIntellectAriseRecognitionProgrammingMost PowerfulReal WorldAbstractionSimilarityComputer ProgrammingProgramming LanguagesComputer Language Author:Tony Hoare
“Another effective [debugging] technique is to explain your code to someone else. This will often cause you to explain the bug to yourself. Sometimes it takes no more than a few sentences, followed by an embarrassed "Never mind, I see what's wrong. Sorry to bother you." This works remarkably well; you can even use non-programmers as listeners. One university computer center kept a teddy bear near the help desk. Students with mysterious bugs were required to explain them to the bear before they could speak to a human counselor.” MindHumansWellsSometimesHelpingUseSpeakCausesLearningStudentsBearsComputerSorryUniversitySentencesTechniqueMysteriousCodeBotherProgrammingDesksListenersEmbarrassedBugsProgrammersTeddyCounselorTeddy BearDebugging Author:Brian Kernighan
