Experimental Strategies and Conceptual Change
The article The Development of Scientific Reasoning in Knowledge-Rich Contexts
written by Leona Schauble relates a series of experiments which give some insight as to
how conceptual change and experimental strategies effect subjects of varying ages, ten
fifth and sixth graders and ten noncollege adults. The conclusions drawn from the article
are relevant in determining the cognitive strengths and weaknesses in the subjects as well
as how these strengths and weaknesses vary as a result of differing ages. The objective of
the study was to track changes in both the theories and reasoning strategies used by
participants who conduct and interpret repeated cycles of experiments over several
sessions to learn about the causal structure of two physical science systems. The exact
experiments are not needed to understand the results of the experiments as long as the
experimentation strategies and conceptual changes are......
