Proportional Reasoning and Control of Variables in Seven Countries. Advancing Education Through Science-Oriented Programs, Report ID-25.
Karplus, Robert; And Others
Reported are the results of a study of the Piagetian formal thought range of 3600 students, 13 to 15 years old, in seven countries: Denmark, Sweden, Italy, United States, Austria, Germany, and Great Britain. Cognitive measurement was obtained by group administration of two tasks to assess proportional reasoning and control of variables. Overall results found 25% of the students at the formal level, 32% of the students in a transition level, 15% of the students at an additive level, and 28% of the students at an intuitive level. Scoring procedures and summary results for each country are also included. (SL)
