5. Review Comments to the Author

Please use the space provided to explain your answers to the questions above. You may also include additional comments for the author, including concerns about dual publication, research ethics, or publication ethics. (Please upload your review as an attachment if it exceeds 20,000 characters)

Reviewer #1: Interesting idea of this study, my recommendations are the following:

Abstract – I recommend rewriting the first sentence, mention ... for increasing physical activity (PA), it is not clear and logical, you can possibly use another verb such as: practicing or increasing the duration of practicing PA or actively involving in PA.

I recommend reviewing the keywords, certain words do not appear from the title of the study such as: Sport and exercise sciences; Social sciences. Also Academic achievement; Academic performance; in conclusion, I recommend clarifications.

Line 20- PA cannot increase, this association of words is inappropriate, I recommend rewriting.

Primary education in Finland – I recommend mentioning how many hours/week of PA are provided for in the curriculum in primary education.

Participants and procedures – according to the information regarding the year of this study, I recommend adding clarifications regarding the difference of 12 years that have passed since 2013. I also recommend mentioning whether in those 12 years there have been changes to the curriculum structure at the primary education level. In my opinion, 12 years represents a major gap both socially and psychologically due to technological and methodological influences at the educational level. I recommend making justifications regarding the aforementioned.

I recommend that all acronyms be mentioned descriptively under the tables.

In conclusion, the study is well organized, the information has a scientific logic and is relevant.

Reviewer #2: The purpose of this study was to examine how classroom peer ecology is associated with PA and ST during school hours, and how these factors relate to academic achievement among primary school students. Subjects were 517 Finnish primary school students (53% girls, 47% boys, Mage = 11.6 years) participated in this study in 2013. Students’ perceptions of classroom peer ecology were investigated through a survey. In addition, moderate-to-vigorous PA (MVPA) and ST during school hours were measured by hip-worn accelerometers. Moreover, grade point averages were calculated based on subject grades. Besides, gender-specific associations were investigated through multigroup structural equation modeling analyses. Results of this study indicated that, positive classroom peer relations were associated with lower levels of in-school MVPA, while greater in-school ST was linked to higher grade point average in girls. However, among boys, higher in-school MVPA was related to higher grade point average. No significant associations were found between social variables and in-school ST.

I would like to thank to authors for this interesting study. I believe authors made a such nice introduction section with hypothesis and their problem of statement is vey clear. In addition, this study had a good sample size and appropriate measurement. My question is about validity and reliability of tests and measurements. This should be reported in the study. Moreover, this study needs a strong discussion and conclusion sections with up to date literature review (2023 and above) with practical suggestions for the future. I look forward to seeing edited version of this timely and interesting manuscript. Thank you.

Reviewer #3: Dear Authors,

Thank you for submitting your manuscript. The topic is potentially relevant; however, in its current form the study has several fundamental issues that substantially limit the credibility, reproducibility, and interpretability of the findings. For these reasons, I recommend rejection.

Data availability and compliance with PLOS Data Policy

PLOS requires that all data underlying the reported findings be made fully available without restriction. In the current submission, the underlying dataset is not clearly provided in an unrestricted, accessible form, and the description suggests that access may depend on requesting data from the authors/third parties. This does not meet the expected standard for transparency and reproducibility unless a clearly justified exception is documented and an alternative compliant solution is provided.

Major statistical validity concern: clustered (hierarchical) data not appropriately modeled

The data structure is clustered (e.g., students nested within classes/schools). While the manuscript acknowledges intraclass correlation (ICC), it also states that the final modeling did not incorporate clustering due to technical limitations. This is a serious methodological flaw because ignoring the hierarchical structure can bias standard errors and p-values, inflating statistical significance and undermining inferential validity. This issue affects the core conclusions and cannot be treated as a minor limitation.

Limited explanatory value and weak practical significance

The reported models appear to have very low explanatory power (small R² values) with only a small number of statistically significant pathways. As a result, the added scientific value is limited and the manuscript risks overemphasizing marginal effects that may not be robust.

Study design constraints and temporal relevance

The cross-sectional design does not support causal inference, yet parts of the discussion and implications drift toward causal language and strong recommendations. In addition, the dataset is relatively old, and the manuscript does not sufficiently justify the contemporary relevance and generalizability of the findings to current educational/behavioral contexts.

Over-interpretation of non-intuitive associations without adequate robustness checks

Some reported associations are not intuitive (e.g., unexpected directions of relationships) and are explained largely through post-hoc speculation. The manuscript would require stronger triangulation, sensitivity analyses, and/or alternative model specifications to support such interpretations.

Measurement limitations for key constructs

Using very brief or single-item measures for important constructs (e.g., classroom climate) raises concerns about measurement error and construct validity especially when these measures are used in complex models (e.g., SEM). This further weakens confidence in the reported pathways.

Given the combination of (i) data availability concerns, and (ii) a critical modeling limitation related to clustered data alongside low explanatory power and interpretive overreach I do not believe the manuscript is suitable for publication in its current form.

Please use the space provided to explain your answers to the questions above. You may also include additional comments for the author, including concerns about dual publication, research ethics, or publication ethics. (Please upload your review as an attachment if it exceeds 20,000 characters)

Reviewer #1: No comments. The authors have revised the article in accordance with the above recommendations. I believe that in its current form the article is ready for the journal.

Reviewer #2: I believe the current edited version this manuscript is acceptable. All my questions answered in detail. Thank you.

Reviewer #4: This is an interesting manuscript with a meaningful contribution using objectively measured in-school movement behaviours and academic achievement in primary school students. That combination is valuable, especially because the study uses accelerometer-based school-time MVPA/ST rather than relying entirely on self-report, and because it takes the school/classroom context seriously rather than treating activity as a purely individual behaviour. The research questions are clear and the manuscript is generally well organized. Furthermore, it is very sound science using objectively measured in-school MVPA and ST, the methods are clear and the modeling is well thought out. Most importantly, it has a practical resonance for educators.

Major concerns:

The manuscript repeatedly emphasizes "gendered" or "gender-specific" patterns in the abstract, discussion, and conclusion. But in the MVPA model, the authors explicitly report that constraining the significant paths to equality across genders did not significantly worsen fit, meaning those associations did not significantly differ by gender. Yes, the authors did disclose in the limitations, but the big picture is that the paper cannot say that the MVPA associations did not significantly differ by gender! Interpretation of gender has to be consistent across Results, Discussion, Conclusion...

The study is cross-sectional, the data were collected in 2013, and the explained variance in GPA is quite modest. The models explain only a small proportion of GPA variance, and the authors themselves note that the findings should be interpreted as individual-level associations, not classroom-level effects. However, the manuscript sometimes sounds close to recommending how schools should design physically active school days based on these findings. The Reviewer believes the evidence base here is not strong enough for broad pedagogical recommendations.

The negative association between peer relations and girls' in-school MVPA is interesting, but much of the explanation offered in the discussion goes beyond what the data can support. The manuscript suggests girls may avoid vigorous activity due to social discomfort or exclusion, or that peer norms may favour lower-intensity activity. These are plausible ideas, but they were not measured directly. Consider offering 2-3 alternative explanations with equal weight, including measurement limitations of hip-worn accelerometers and the possibility that socially valued activity for girls may not register well as MVPA.

"Classroom climate" is a rich construct that usually involves emotional safety, norms, teacher support, belonging, participation structure, and sometimes behaviour management or instructional organization. A single item on how students experience the class climate is unlikely to capture that complexity. Explain why this still adds value despite being conceptually thin and avoid overinterpreting null findings for classroom climate.

Minor comments:

The Introduction is good, but it could do a better job distinguishing peer ecology as a broad social context, PA-specific peer support, and classroom climate.

The limitations section is one of the stronger parts of the manuscript. In fact, it is more cautious than the discussion and conclusion. The Reviewer recommends using the limitations section as the tone standard for the whole paper.

Students do not experience activity opportunities only as physical opportunities; they experience them through belonging, peer norms, identity, and classroom culture. The Reviewers ask the Authors to consider making their practice message more about designing activity opportunities that are socially inclusive, not assuming all students experience active school practices in the same way, and considering how classroom and recess social norms shape participation.

Dear Dr. Byman,

Thank you for submitting your manuscript to PLOS ONE. After careful consideration, we feel that it has merit but does not fully meet PLOS ONE’s publication criteria as it currently stands. Therefore, we invite you to submit a revised version of the manuscript that addresses the points raised during the review process.

==============================

ACADEMIC EDITOR:

The revised manuscript has improved substantially and addresses the majority of the reviewers’ and editor’s previous concerns. The study addresses an important and timely topic, and the analyses are generally appropriate and carefully conducted. The manuscript is now close to being suitable for publication. Before a final decision can be made, however, the authors are requested to address several remaining issues through a minor revision:

1. Interpretation of gender differences: While the manuscript appropriately reports some observed differences in association patterns between girls and boys, several formal between-group comparisons were not statistically significant. Please further ensure throughout the Abstract, Results, Discussion, and Conclusions that interpretations remain cautious and do not overstate gender-specific effects where statistical evidence for group differences is limited.

2. Data availability statement: Please revise the Data Availability Statement to ensure full compliance with PLOS ONE data-sharing requirements. In particular, the justification for restrictions on data access should be clarified further, including a more explicit explanation of the ethical or legal constraints preventing public deposition of the dataset and the exact conditions under which data access may be granted.

3. Classroom climate measure: The use of a single-item measure for classroom climate is acknowledged as a limitation. Please strengthen the methodological justification for this choice in the Methods section and briefly elaborate on the implications this may have for interpretation of the findings.

4. Relevance of older data collection period:As the data were collected in 2013, please further clarify in the Discussion why the findings remain relevant to contemporary school contexts and current educational or physical activity practices.

5. Please carefully proofread the manuscript once more for clarity, consistency of terminology, and minor grammatical or stylistic issues.

Reviewer #4: The Reviewer thanks the Authors for responding thoughtfully to the prior comment. A couple of things to address briefly:

1. Was the classroom climate item reverse-coded? Please clarify

2. The Reviewer believes that altering the title to "Gendered patterns in the associations..." is more fitting and would match the conclusion by the Authors better (i.e., patterns were different, but not always statistically different between gender)

3. For Table 4, just make sure the direction of Cohen's d are all correct

4. For Tables 5 and 6, upper should probably be 97.5% rather than 2.5%. Conventionally, the Reviewer recommends 95% CI lower and upper.

5. From the Reviewer's scientific education and bias, a p-value should never be 0.000 - please report at p < 0.001

Open letter on the publication of peer review reports

PLOS recognizes the benefits of transparency in the peer review process. Therefore, we enable the publication of all of the content of peer review and author responses alongside final, published articles. Reviewers remain anonymous, unless they choose to reveal their names.

We encourage other journals to join us in this initiative. We hope that our action inspires the community, including researchers, research funders, and research institutions, to recognize the benefits of published peer review reports for all parts of the research system.
