What the paper did

Castulo, Lansangan and Marasigan performed a descriptive secondary analysis of PISA 2022 Philippine data (7,193 learners; 3,662 female, 3,531 male, mostly grade 10), analyzing three perception items, five confidence items, and eight selected creative-thinking test items from four science-themed tasks, then mapped these against the 2016 grades 7–9 science curriculum via desk review Methods section of PISA analysis. The Philippines placed second-to-last among PISA 2022 creative-thinking performers (mean score 14 vs OECD-referenced Singapore at 41) ASEAN creative thinking rankings.

Figure 1. Reported credit frequencies on the eight selected items (Table 6). Note the inverted scoring pattern: science fair poster items yielded high partial credit and low no-credit, while carpooling Q1 and save-the-river Q1 yielded predominantly no credit — heterogeneous item difficulty that the paper's narrative understates.

Critical findings and red flags

• Narrative–table contradiction. The text claims "most learners... yielded no credit," but science fair poster Q1 shows 434 partial-credit vs only 77 no-credit responses — the authors' own counterevidence Table 6 credit frequencies.
• Arithmetic inconsistencies. Text reports science fair poster Q1 full credit as "f=76 or 7%", but 76 is ~1% of 7,193; item totals also do not sum to 7,193 and item-level Ns vary due to missingness, which the authors acknowledge Missing values acknowledgment.
• Duplication. A full paragraph on save-the-bees and save-the-river alignment is repeated verbatim in the results section.
• No inferential statistics. Gender differences (e.g., female 2.66 vs male 2.62 on "I am very creative") are described without significance tests or PISA sampling weights, so the "mismatch" interpretation between confidence and performance rests on descriptive contrast only Absence of inferential statistics.

Interpretation and limitations

The misalignment conclusion is qualitative and defensible in direction — only carpooling partially matched a grade 9 climate-change standard — but the desk review lacked formal alignment criteria, a known challenge in the alignment literature the authors cite Alignment criteria limitations. Self-reported confidence (Likert 2.51–2.73, all "confident") cannot be causally compared to item performance without psychometric controls, and only 8 of 9 creative-thinking themes were examined Scope limitations. The ecopedagogy recommendation is an author hypothesis, not tested in the study. What would change the conclusion: a weighted, formally coded alignment analysis showing substantial matches, or partial-credit-sensitive scoring (as in Figure 1) reframing the "lack of proficiency" claim.

Study Novelty

First use of PISA 2022 creative-thinking item-level data against Philippine curriculum standards, but PISA creative-thinking analyses and curriculum-alignment desk reviews are established genres; the ecopedagogy angle is incremental.

Scientific Quality

Descriptive only, no inferential statistics, sampling weights, or formal alignment rubric; verbatim duplicated paragraph; text-table contradictions (e.g., '76 or 7%') and no item-total reconciliation despite disclosed missingness. Data provenance and ethics exemption are appropriate.

Study Generality

Findings are specific to Philippine grades 7-9 science and eight PISA items; the perception-performance mismatch motif generalizes only as a hypothesis.

Study Usefulness

Actionable reference for Philippine curriculum developers and EDCOM 2 discourse; weak quantitative leverage for international readers beyond confirming the country's low creative-thinking ranking.

Study Reproducibility

OECD data are publicly available and the analysis is simple, but no code, no weight specification, inconsistent reported counts, and subjective desk-review criteria limit exact replication.
