The purpose of this study was to develop a model for measuring experimental design ability based on functional
magnetic resonance imaging (fMRI) during biological inquiry. More specifically, the researchers developed an
experimental design task that measures experimental design ability. Using the developed experimental design
task, they measured both the paper experimental design ability and the fMRI experimental design ability of subjects.
Subjects’ paper experimental design ability was measured using the quotient equation of experimental
design ability, and their fMRI experimental design ability using the brain connectivity coefficient. According to
the fMRI results, differences in design ability existed among subjects in terms of brain connectivity coefficient
level during the experimental design task. The experimental design ability brain connectivity coefficient level
and quotient for each subject were analysed. Statistically significant correlations between subjects’ connectivity
strength level among brain activation regions and quotient value guided the establishment of a measuring
model. The model measured experimental design ability and could predict an individual’s experimental design
ability quotient using his or her brain connectivity coefficient. Hence, the model developed for this study for
measuring experimental design ability based on fMRI may serve as a practical measurement of students’
scientific experimental design ability. Furthermore, this study could serve as a founding theory for measuring
models of other scientific processing abilities such as observation, question generation, classification, hypothesis
generation and hypothesis evaluation.
