查询词典 purse string

In the first part, study 1 was designed to investigate the development of the science inquiry ability in the group of the primary and secondary School student, and how the task difficulty affects science inquiry. We used the self-directed, computer simulated inquiry task, namely pendulum and string task It required the subjects to find the factors that affected the swing frequency of the pendulum and the level of stretch of the string. To evaluate the ability of science inquiry, we analyzed subjects'experiment-design strategies, evidence-evaluation strategies, and results of inference.
