Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q3 i? Descriptively, the PISG sequence showed more occurrences of high-level generating evidence, evaluating evidence, and drawing conclusions than PSGI, but the differences were not statistically significant and effect sizes were small. → Esther Tan 2018
Evidence¶
Esther Tan 2018¶
Esther Tan (2018). Effects of two differently sequenced classroom scripts on common ground in collaborative inquiry learning. Instructional Science. https://doi.org/10.1007/s11251-018-9460-6
q3 · i? · causal · r2
Quantitative analysis of coded discourse from 20 groups (PISG n = 32, PSGI n = 29) across the three collaborative inquiry processes: "PISG script sequence facilitated more occurrences for high-level generation of evidence, high-level evaluation of evidence and high-level drawing of conclusions," but "there was no statistical significance and the effect sizes were small."
"overall descriptive findings showed that PISG script sequence facilitated more occurrences for high-level generation of evidence, high-level evaluation of evidence and high-level drawing of conclusions as compared to the PSGI script condition, again, there was no statistical significance and the effect sizes were small"
Esther Tan 2018 (2)¶

q3 · i? · causal · r2
The same analysis on low-level inquiry processes found "the PISG script condition reduces the occurrences of all three low-level inquiry processes but the results were not significant"; no effect size value is printed in this sentence.
"Similarly, findings showed that the PISG script condition reduces the occurrences of all three low-level inquiry processes but the results were not significant."
Discussion¶
Related Claims¶
- In the PISG case study, occurrences of high-level grounding and high-level testing co-occurred with more occurrences of high-level inquiry processes — related
- In the PISG script, students' field-trip individual observations were largely off-target for the chosen plant, while by the post-field trip individuals showed some improvement in scientific thinking — related
- The PISG and PSGI classroom script sequences showed no statistically significant difference in high- and low-level grounding and testing processes, alongside a trend favoring PISG — related
- In the case discourse, failure to integrate individuals' ideas with sound verification was linked to low-level inquiry outcomes, while successful high-level grounding enabled groups to integrate ideas and negotiate shared knowledge — related
- Evidence-based rubric scripting produced more high-quality discussion than future-thinking scripting in long-term small-group collaboration. — related
