In a small Chinese graduate course, idea-centered scaffolding best strengthened connections among ideas, metacognitive regulation, and knowledge-artifact work during CPS.

Role on claims
Each row is a claim on a concept or method page where this paper supports, challenges, or qualifies the statement. Roles are hand-checked — not a model guess.
An eight-week graduate Distance and Online Education course compared minimally guided, task-oriented and idea-oriented scaffolds for triad collaborative problem-solving. Ten volunteers joined; one withdrew, leaving about nine analysed participants. Idea-centred scaffolding strengthened links among idea contribution, metacognitive regulation and knowledge-artefact behaviours in this sample. That n makes the ranking exploratory, not a definitive scaffold league table.
Evidence for the claim as stated.
Unit of assignment and what 'worked' do not match. DES assigns schools (746 vs 667 students) and reports engagement. MIM assigns historical cohorts (26 vs 28 quiz completers) and reports interaction on optional tasks. The ITS paper randomises individuals after exclusions and reports an adjusted post-test. Faculty training has no comparison group. Scaffolding compares conditions among ~9 volunteers. These are not six estimates of one quasi-experimental engagement effect.

Which scaffolding helps online collaborative problem-solving?
These passages occur verbatim in the stored paper text. They support the points listed below; they do not verify every statement in the explanation.
Ten participants volunteered; one withdrew
Ten participants voluntarily participated and agreed with the data collections; one participant withdrew the participation in the middle of the semester, which was excluded from the research (see Table ).
What learning mode was studied?
The research context was the online, synchronous CPS activity in China’s higher education context.
Key findings
Idea-centered collaboration strengthened links among idea contribution, metacognitive regulation, and knowledge-artifact behaviors, supporting higher CPS quality. Authors conclude idea-centered scaffolding was the most useful strategy in this sample, while noting task-oriented scaffolds may help students who need more structure if idea-centered elements are integrated.
Methodology
In an 8-week graduate Distance and Online Education course, small triads solved authentic online-education problems under different scaffoldings (including minimally guided, task-oriented, and idea-oriented approaches). Researchers analyzed collaborative problem-solving processes across metacognitive, behavioral, and temporal dimensions.
Limitations
Only about nine analyzed volunteer participants after one withdrawal, in one course and short window, so findings are exploratory rather than definitive comparisons for all CPS settings.
