## IMRAD Structure

### Standard Research Paper Format
```
I - Introduction (What's the question?)
M - Methods (How did you study it?)
R - Results (What did you find?)
A - And
D - Discussion (What does it mean?)
```

### Section Guidelines

#### Introduction
```
Structure (Inverted Triangle):
1. Broad context (field overview)
2. Narrower context (specific topic)
3. Gap in knowledge
4. Research question/hypothesis
5. Brief approach description

Key Elements:
- Hook with significance
- Literature review highlights
- Clear problem statement
- Objectives stated explicitly
```

#### Methods
```
Purpose: Reproducibility

Include:
- Study design
- Participants/samples
- Materials/equipment
- Procedures (step-by-step)
- Data collection methods
- Statistical analyses
- Ethical considerations

Write in: Past tense, passive voice acceptable
```

#### Results
```
Purpose: Present findings objectively

Structure:
1. Start with primary findings
2. Present in logical order
3. Use tables/figures effectively
4. Statistical results with p-values
5. No interpretation here

Format: Past tense
Example: "Participants showed a significant increase (p < 0.05)"
```

#### Discussion
```
Structure (Reverse of Introduction):
1. Summary of key findings
2. Interpretation and meaning
3. Comparison with literature
4. Limitations
5. Implications
6. Future directions
7. Conclusion

Avoid: Overgeneralizing, ignoring limitations
```

## Abstract Writing

### Structured Abstract (250 words)
```
Background: Why is this important? (2-3 sentences)
Objective: What did you study? (1 sentence)
Methods: How did you do it? (2-3 sentences)
Results: What did you find? (3-4 sentences)
Conclusions: What does it mean? (1-2 sentences)
```

### Graphical Abstract Concept
```
Question → Method → Key Finding → Significance
[Visual representation of the paper's story]
```

## Scientific Writing Style

### Clarity Principles
```
- One idea per sentence
- Active voice when possible
- Strong verbs (not "it was found")
- Avoid jargon (or define it)
- Precise word choice
```

### Common Fixes
```
Wordy: "Due to the fact that"
Better: "Because"

Wordy: "In order to"
Better: "To"

Wordy: "At this point in time"
Better: "Now"

Vague: "Many studies show"
Better: "Smith et al. (2023) demonstrated"
```

### Hedging Language
```
Strong claim: "X causes Y"
Hedged: "X may contribute to Y"
"Results suggest that..."
"Data indicate that..."
"It appears that..."
```

## Citations and References

### In-Text Citation Styles
```
APA: (Smith, 2023) or Smith (2023)
Vancouver: [1] or superscript¹
Harvard: (Smith 2023)
```

### Citation Integration
```
Weak: "Research shows X (Smith, 2023)."

Strong: "Smith (2023) demonstrated that X,
supporting earlier findings by Jones (2020)."
```

## Figures and Tables

### Figure Guidelines
```
- Self-explanatory with legend
- High resolution (300+ DPI)
- Consistent style
- Clear labels
- Referenced in text
```

### Table Guidelines
```
- Use for precise values
- Clear headers
- Consistent decimals
- Note significance markers
- Don't duplicate figure data
```

## Peer Review Response

### Response Letter Structure
```
Dear Editor,

Thank you for the opportunity to revise...

REVIEWER 1

Comment 1: [Quoted comment]
Response: [Your response]
Changes: [Page/line references]

[Repeat for each comment]

```

### Response Strategies
```

Partially agree: "We appreciate this point. However..."
Disagree: "We respectfully differ... Our reasoning is..."
```
