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 understood. The experimentation strategies approach tends to emphasize concern for logical validity, (i.e. how the problem pieces together and why). The conceptual change approach tends to be more concerned with the plausibility and explanatory coherence as tests for deciding whether knowledge should be adopted. Schauble (1996) states that "because previous work focused either on the validity of strategies or the coherence of conceptions, it has tended to mask these close interrelations" (p.102). Therefore the re...
