Subclaims¶

q3 i? Participants showed an overwhelming preference for V1 when asking Part-scoped questions. → scope-pref q3 i? Preference shifted with question complexity: V1 was preferred for short Definition and Description questions, while a trend toward the baseline emerged for longer, more interpretive questions. → content-pref

q3 · i? · causal · r1

Study 1 question-scope analysis (N=16, within-subjects) classifying targeted elements as Whole or Part; Figure 4(B) preference data show V1 strongly preferred for Part-scoped questions where spatial referencing is crucial. For general Topic targets participants favored the baseline.

"According to the preference data (Figure 4(B)), participants showed an overwhelming preference for usingPenquiryV1 when asking thesePart-scoped questions."

q3 · i? · design · r3

Study 1 question-content analysis using the Scardamalia and Bereiter framework; Figure 4(C) shows V1 preferred for short Text-based questions, while "a trend toward preferring the baseline emerged" for interpretive questions, which participants said were faster to type.

"According to the preference data (Figure 4(C)), participants showed a significant preference forPenquiryV1 when asking shorter questions, such as Text-based (Definition) and Text-based (Description)."
