Investigative Report Writing Workbook – Quick-Reference Notes

Preface & Purpose

• Workbook stems from research on linguistic errors in criminology students’ investigative reports.
• Targets recurring issues: grammar, sentence construction, subject–verb agreement (SVA), word usage, punctuation.
• Designed for classroom or self-study; aims to improve clarity, accuracy, and professionalism in law-enforcement writing.

Workbook Concept & Benefits

• Workbook = structured, exercise-driven learning tool.
• Promotes active learning, self-assessment, and idea organization.
• Bridges theory ↔ practice through contextualized criminology tasks.
• Caveat: effectiveness depends on relevant, high-quality design.

Identified Writing Challenges

• Frequent SVA and verb-tense errors; sentence fragments & run-ons.
• Misuse of criminological terms; limited vocabulary.
• Time pressure → rushed, grammatically weak submissions.
• Inconsistent punctuation/mechanics obscure meaning.

Workbook Objectives

• Cognitive

• Diagnose & correct sentence-fluency issues (fragments/run-ons).
• Reduce jargon; write clear, concise reports.
• Master grammar/syntax when using field-specific terms.
  • Affective
• Build confidence; value clarity; embrace peer collaboration.
  • Psychomotor
• Practise revising/editing; use digital writing tools; conduct peer review.

Technical Writing Essentials (Criminology)

• Definition: field-specific communication conveying precise info to defined readers.
• Key elements: subject matter, purpose, study/investigation, organized presentation.
• Principles: know reader & purpose; use concrete language; follow standard format.
• Police reports must be $\text{clear}$, $\text{factual}$, $\text{concise}$.
• 6 × W/H outline: Who, What, When, Where, Why, How.

Report-Writing Value

• Organizational: decision-making, accountability, records, legal documentation.
• External: supports prosecutors/courts; informs other agencies & media.
• Individual officer: information exchange, investigative continuity, reflects personal professionalism.

Common Grammar Errors Overview

1. Subject-Verb Agreement (SVA)
2. Verb-Tense Consistency
3. Articles (a, an, the)
4. Pronoun–Antecedent Agreement
5. Additional: syntax, prepositions, pluralization, sentence fragments/run-ons.

Subject–Verb Agreement Highlights

• Singular subject → verb + $s$: "The detective investigates."
• Plural subject → base verb: "Detectives investigate."
• Compound subjects joined by "and" → plural verb.
• Indefinite pronouns (everyone, each) → singular verb.
• Collective nouns: singular if acting as one unit; plural if acting individually.
• Titles/amounts treated as singular: "Five pesos is enough."

Verb Tense Consistency Highlights

• Maintain one tense within a context unless timeline shift is required.
• Acceptable shift must be clear & purposeful (flashback, future action, etc.).
• Present simple = habitual/current; Past simple = completed; Future simple = planned.
• Example error: "The detective investigates and collected evidence." → keep both present or past.

Proper Use of Articles

• Definite article "the" → specific, known noun.
• Indefinite articles "a / an" → non-specific or first mention.
• Correct articles = precision, professionalism, avoidance of ambiguity.
• Consistency crucial when repeatedly referencing same item (e.g., "the evidence").

Pronoun–Antecedent Agreement

• Pronoun must match antecedent in number & gender.
  • Singular: "Each officer presented his report."
  • Plural: "All officers presented their reports."
• Clarity: ensure pronoun clearly points to one antecedent; avoid vague "it/they."

Grammatical Accuracy Components

• Syntax (word order), punctuation, verb tense, SVA, sentence completeness, precise vocabulary.
• Accuracy → clarity, professionalism, credibility.

Syntax Essentials

• English default word order: Subject–Verb–Object.
• Sentence forms:
  • Simple: one independent clause.
  • Compound: two independent clauses + conjunction/comma.
  • Complex: independent + dependent clause(s).
• Phrase types: noun phrase ("the experienced detective"), verb phrase ("has been investigating"), prepositional phrase ("at the crime scene").

Prepositions Essentials

• Place: in, on, at, under, between.
• Time: at $9\,\text{AM}$, on Monday, in 2024.
• Direction: to, into, toward, across.
• Manner/agent: by, with.
• Common pitfalls: wrong choice ("good in math" → "good at math"), omission ("responsible for"), overuse.

Pluralization Rules

• Regular: +$s$ (dog→dogs).
• Ends in s,x,z,sh,ch: +$es$ (box→boxes).
• Consonant + y: $y\rightarrow ies$ (city→cities); vowel + y: +$s$ (key→keys).
• $f/fe\rightarrow ves$ (knife→knives); some just +$s$ (roof→roofs).
• Irregular: man→men, child→children, mouse→mice.
• Compound: pluralize principal word (mother-in-law → mothers-in-law).

Common Sentence Errors

• Fragments: incomplete thought ("Because the suspect fled.").
• Run-ons: independent clauses merged w/o conjunction/punctuation.
• Comma splices: comma used alone between independent clauses.
• Fixes: add conjunction, period, semicolon, or revise clause.
