Which strategy best explains how to solve this problem? colin is preparing for a marathon by running in his neighborhood. the first week, he runs one block. the next week, he runs twice as many blocks as the first week (2 blocks). each week, he plans to run twice as many blocks as he ran the week before. how many blocks will colin run by the end of the sixth week? a. use objects to model the problem. put out 1 chip to represent the blocks run in week one. put out twice that amount for week two. put out twice that amount (from week two) for week three. do this 3 more times, putting out twice the amount from the previous week each time. b. make a table. in the first row, write first week - 2 blocks. in the next row, write second week - 4 blocks. in the third row, write third week -6 blocks. continue this pattern for three more rows. c. write a number sentence. (1 + 2) × 6 = x add the number of blocks run in the first and 2nd week. then multiply the sum by the number of weeks (6).

Study published in the journal of personality and individual differences found that adults with adhd displayed more creative achievement than those who didn't have the disorder. "for the same reason that adhd might create problems, like distraction, it can also allow an openness to new ideas," says holly white, assistant professor of cognitive psychology. "not being completely focused on a task lets the mind make associations that might not have happened otherwise." white and priti shah at the university of michigan gave 60 college students – half of them with adhd – a series of tests measuring creativity across 10 domains. the adhd group scored higher across the board. the adhd group showed more of a preference for brainstorming and generating ideas than the non-adhd group, which preferred refining and clarifying ideas. the adhd status of the participants was established by asking whether the individual had ever been clinically diagnosed with adhd/add. the tests of creativity were pencil-and-paper tasks administered in a laboratory setting. each of the ten scales was comprised of multiple questions, the scores on which were summed (e.g., writing creativity: "how many words can you make from the letters in the word 'psychology' invention creativity: "write down as many uses for a paper clip that you can think of.") this procedure does allow for a participant to be scored as showing no creativity under these conditions. a) state the research question in plain language (i wonder if is related to (1 point) b) state the null hypothesis (1 point) c) state the research hypothesis (1 point) d) is the research hypothesis directional or non-directional (1 point) e) name the predictor / independent variable f) give the operational definition of the predictor / independent variable g) evaluate the construct validity of the predictor / independent variable. (face, procedure, method-match) h) name the outcome / dependent variable i) give the operational definition of the outcome / dependent variable. j) evaluate the construct validity of the outcome / dependent variable.
