Subclaims¶

q2 i? In a study with a short initial phase, PS-I was less beneficial for transfer than WS-I; in a second study with a long initial phase, PS-I was more beneficial. The contrast is across two separate studies, and the article says a shared-sample study is needed to test whether duration explains it. → Katharina Loibl · Timo Leuders · Inga Glogger-Frey · Nikol Rummel 2025 q2 i? In the long-preparation study, PS-I was more beneficial for transfer than WS-I. → Katharina Loibl · Timo Leuders · Inga Glogger-Frey · Nikol Rummel 2025 (2)

q2 · i? · theoretical · r3

The article reports Glogger-Frey et al.'s (2015) study with one problem-solving or worked-solution task before instruction on density/ratios, finding PS-I "less beneficial for transfer" than WS-I. The article contrasts it with the long-phase 2017 study, says the two differed only in phase duration, and notes that research with a shared sample is needed to test whether this cross-study comparison is valid.

"The results of the first study (Glogger-Frey et al., 2015; short PS1/WS1) revealed that PS-I was less beneficial for transfer than explaining the worked solution before instruction"

q2 · i? · theoretical · r3

The article reports Glogger-Frey et al.'s (2017) study with two problems in the initial phase, finding PS-I "more beneficial for transfer" than WS-I. The CID framework proposes, as a theoretical explanation rather than a tested result, that working on two problems in different contexts gives an opportunity for analogical encoding, so the intermediate knowledge should be more generalized.

"The second study, with the long problem-solving or worked-solution phase (Glogger-Frey et al., 2017), revealed that PS-I was more beneficial for transfer than explain-ing the worked solution before instruction (WS-I)."

Discussion¶

Related Claims¶

• PS-I research demonstrates beneficial effects on conceptual knowledge and knowledge transfer relative to I-PS — related
• Across studies, high solution rates in the initial problem-solving phase co-occur with beneficial PS-I effects and low rates with no beneficial effects, a cross-study pattern not yet tested in a shared sample — related
• Productive Failure Improves Conceptual Learning — a broader claim this one bears on
• In a Bayesian-reasoning replication, problem-solving prior to instruction (PS-I) showed no significant advantage over instruction-first (I-PS) on conceptual knowledge — related
• Sense-making-first preparation supports learning more strongly than fluency-first because conceptual intermediate knowledge alters second-phase learning processes — related
• PS-I fosters learning only if specific design features (contrasting cases or building instruction on student solutions) are implemented — related
