Criteria Feedback
- You identify a clear interdisciplinary topic and keep it connected to the snow-crab collapse case study.
- Your research question is evaluative and specific enough to guide the investigation.
- You show awareness of relevant source types and attempt to justify why the evidence is appropriate.
- The focus drifts into broad background material at points instead of staying tightly on the question.
- The research question is still a little broad because it does not fully define the exact policies or time frame being tested.
- The method is implied rather than clearly designed, so the reader cannot easily see how evidence was selected and compared.
1.1·Suggestion
Page 1
Consider specifying the exact economic indicators that will be used to judge “address” — for example revenue recovery, employment, tax income, or market share. That would make the investigation method much more measurable and easier to evaluate.
1.2·Weakness
Page 1
The question is still too broad because “implementing sustainable fishing practices” could mean closures, quotas, rebuilding plans, monitoring, or diversification. The student should narrow the interventions and identify a clear time frame so the answer can judge effectiveness more precisely.
1.3·Strength
Page 1
The research question is clearly framed as an evaluative inquiry and links biology with economics in a specific case study. The phrase “To What Extent” gives the essay a clear direction, which is a strong foundation for focused investigation.
1.4·Strength
Page 3
This sentence clearly justifies the interdisciplinary approach and shows why both subjects are needed. It helps the reader understand the logic of the investigation rather than treating biology and economics as separate topics.
1.5·Weakness
Page 4
The source discussion describes NOAA’s authority, but it does not yet explain a concrete method for selecting, comparing, or weighing evidence. The student should state how sources will be used to evaluate economic effectiveness, not only why NOAA is credible.
1.6·Suggestion
Page 5
The student could strengthen the methodology by adding a brief sentence on source selection criteria, such as prioritizing peer-reviewed studies for ecological mechanisms and official fisheries data for harvest and revenue outcomes. That would show intentional method rather than general source use.

Criteria Feedback
- You demonstrate sound knowledge of the snow-crab ecology and the economic importance of the fishery.
- You use several relevant academic and official sources to support factual claims.
- Your terminology is generally accurate and appropriate to both biology and economics.
- The two disciplinary lenses are often presented one after the other rather than fully integrated.
- Some source choices are stronger than others, and not all potentially relevant evidence is used equally well.
- The economic concepts are present, but they are not developed with enough precision or depth.
2.1·Weakness
Page 6
The figure is introduced, but the essay does not fully interpret the key trend shown in the data. The student should refer directly to the visible change in abundance and explain how the graph supports the ecological argument.
2.2·Strength
Page 6
The figure is highly relevant because it provides a visual trend for the collapse being discussed in the prose. Using the graph alongside the written explanation strengthens the factual basis of the investigation.
2.3·Weakness
Page 7
This source is used in a general way, but the link to the Bering Sea case is not fully developed. The student should explain more explicitly how global phytoplankton changes translate into the local snow crab problem rather than leaving the connection implied.
2.4·Strength
Page 7
The student demonstrates strong biological understanding by explaining the food-web role of phytoplankton before connecting it to crab survival. This builds a logical ecological chain and shows accurate use of disciplinary knowledge.
2.5·Strength
Page 8
This is a strong use of academic evidence because it connects a peer-reviewed study directly to the central ecological claim. The student is not just describing the heatwave, but tying it to a specific causal explanation for the collapse.
2.6·Weakness
Page 8
The wording stays cautious with “associated,” but the paragraph still edges toward causation without fully separating correlation from proof. The student should distinguish clearly between what the study demonstrates and what it suggests, especially when making ecological claims.
2.7·Strength
Page 9
This is effective economic evidence because it quantifies the fishery’s importance before the collapse. Using concrete revenue data helps the essay move beyond general claims about “importance” and makes the economic stakes visible.
2.8·Weakness
Page 10
This claim is important, but it would be stronger with clearer source support and more precise wording. The student should avoid vague phrasing like “vastly indigenous” and instead explain exactly how local dependence on crab revenue affects economic resilience.
2.9·Strength
Page 11
This shows solid understanding of the management framework governing the fishery. The student clearly identifies the institutions involved, which gives the later discussion of policy a useful factual base.
2.10·Suggestion
Page 12
The essay would be stronger if the student briefly explained what made Amendment 53 economically relevant beyond being a management change. Linking the rebuilding rules to a measurable economic outcome would show deeper integration between biology and economics.

Criteria Feedback
- You build a recognizable argument linking ecological disruption to economic harm and then to management responses.
- You make some good analytical moves when explaining how warming, habitat change, and predation interact.
- You reach a definite overall conclusion rather than leaving the investigation open-ended.
- The argument is often descriptive, with limited comparison of different management measures and their outcomes.
- Your conclusion is broader than the evidence fully supports because it does not weigh specific policies against specific results.
- Several sections describe useful background or future projects without clearly showing how they answer the research question.
3.1·Strength
Page 6
The figure is useful evidence because it anchors the narrative of collapse in a visible data trend. When used well, visual evidence like this can strengthen analysis by showing scale and timing rather than relying only on descriptive language.
3.2·Weakness
Page 6
The student includes the data source, but the analysis does not yet extract enough meaning from the trend itself. The student should discuss what the specific drops between the labelled years imply about the severity and pace of the collapse.
3.3·Strength
Page 8
This is a strong analytical move because the student compares laboratory tolerance with real ecological conditions. That distinction shows more sophisticated reasoning and helps explain why simplified temperature arguments are not enough.
3.4·Weakness
Page 10
The conclusion here is plausible, but it is asserted more than demonstrated. The student should support this claim with evidence about market share, substitution, or recovery time rather than relying on a hypothetical outcome.
3.5·Question
Page 12
If limited directed fishing is allowed during rebuilding, how far can the student show that this policy actually reduced economic harm rather than simply delaying losses? A comparison with the counterfactual of continued closure would make the evaluation much stronger.
3.6·Suggestion
Page 13
The student could turn this into more incisive analysis by comparing which of these adaptation measures would most directly address the economic repercussions identified earlier. Ranking the options would help the argument move from description to evaluation.
3.7·Weakness
Page 14
This section describes ACLIM well, but it does not yet evaluate how the model helps answer the research question. The student should explain what evidence from ACLIM actually shows about economic repercussions or management effectiveness, rather than presenting the project as inherently useful.
3.8·Weakness
Page 16
The conclusion shifts toward the future prospects of the fishery, but it still does not directly answer whether sustainable fishing practices addressed the economic repercussions already identified. The student should keep the final judgement tied to the research question rather than broadening it into a general forecast.
3.9·Weakness
Page 17
The judgement is too general because it does not distinguish between different management measures or explain which ones were ineffective, partially effective, or promising. The student should make the conclusion more analytical by weighing specific policies against specific outcomes.
3.10·Strength
Page 17
This conclusion is clearly stated and returns to the central evaluative claim. The student shows an ability to reach a definite overall judgement, which gives the essay a coherent endpoint.

Criteria Feedback
- You include a clear title, logical sectioning, and a conclusion that makes the report easy to follow.
- Your visuals are relevant to the topic and are numbered and captioned.
- You include in-text citations and a works cited section, showing academic awareness.
- Some source details are incomplete or inconsistent, which makes the referencing less precise than it should be.
- A few structural sections are too prominent or descriptive and interrupt the flow of the argument.
- The visuals are present, but they are not always used analytically enough to deepen the discussion.
4.1·Weakness
Page 2
This standalone section heading is too prominent for what is essentially source evaluation, and it interrupts the flow of the investigation. The student should integrate source appraisal into the argument more smoothly rather than isolating it as a large structural block.
4.2·Suggestion
Page 2
The table of contents could be refined by aligning subsection titles more closely with the actual analytical progression of the essay. A more precise contents page would better reflect the argument structure and improve navigability.
4.3·Strength
Page 2
The report has a clear academic structure with a visible introduction, topic sections, and conclusion. This helps the reader follow the investigation and makes the line of argument easier to navigate.
4.4·Strength
Page 9
The division into biological and economic lenses is a clear and effective structural choice for a World Studies essay. It signals interdisciplinary thinking and helps the reader understand how the evidence is being organized.
4.5·Weakness
Page 12
The section title is useful, but the surrounding discussion is still mostly descriptive. The student should use the section to compare the rebuilding plan with earlier management responses so the structure supports evaluation rather than summary.
4.6·Strength
Page 19
The presence of a substantial works cited page shows appropriate academic convention and source awareness. This supports the credibility of the investigation and gives the reader a route to verify evidence.
