About This Case Study

This case study presents the QA review process applied to a 155-slide eLearning course Script covering food waste management for everday households. The script spanned 10 content sections — from definitions and taxonomy to practices and habits — and required a comprehensive quality check to ensure pedagogical soundness before production.

The Challenge

The first version of this AV script presented recurring structural, tonal, and alignment issues across multiple content sections. Without systematic QA intervention, these gaps would have reached production, affecting learner comprehension and course credibility.

The QA Specialist's Responsibility

As the Senior Instructional Design QA Specialist, my role was to ensure the AV script met the learning objectives, maintained pedagogical integrity, and was production-ready. This meant examining every slide for structural soundness, content accuracy, tonal consistency, and alignment with the course framework (AREL: Argument, Reasoning, Evidence, Link-back).

"Hi Samantha, Thank you for creating the Food Waste course! I've reviewed the AV script and have a few concerns. Could you please take a look at my comments? Let me know if you have any questions or need my assistance — I'd be happy to help."

— Siti Nuraeni, opening comment to the instructional designer

This framing — constructive, collaborative, and solution-oriented — reflects the core philosophy of high-quality QA: feedback should empower, not criticize. Every comment in this review was designed to guide the instructional designer toward a stronger output while preserving their creative contribution.

01

Full Script Read-Through

Read all 155 slides in context, cross-referenced against the Handover Document and Master File guidelines to understand the intended learning journey.

02

Learning Objective Mapping

Checked each section's content against its stated learning objective to verify that voice-over and slide text actively served learner outcomes.

03

AREL Framework Audit

Evaluated the structural flow of each argument — verifying that thesis, body, evidence, and conclusion slides followed a coherent pedagogical sequence.

04

Tone and Readability Check

Flagged casual phrasing, personal pronouns, and vocabulary that was too technical or too informal for the semi-formal eLearning register.

05

Positive Reinforcement

Identified strong examples of thesis writing and content flow to set a standard for the ID and encourage consistent quality across all sections.

Six Categories of Quality Feedback

Rather than offering ad hoc observations, the QA review was systematically organized around six recurring issue types. This approach gives instructional designers a clear, learnable framework for improvement.

🏗 Structural / AREL
~28

Slide Structure & AREL Flow

Comments flagging misplaced information across thesis, body, and evidence slides. Many body slides contained thesis-level content, and vice versa. Correcting this was the single highest-impact improvement needed.

📖 Clarity
~18

Readability & Coherence

Sentences that were too dense, choppy, or difficult to read as voice-over. Included requests to define key terms, improve sentence flow, and synthesize studies rather than listing them sequentially.

🎯 Alignment
~16

VO & Slide Text Alignment

Cases where slide text did not reflect the voice-over content, or where the content diverged from the course objective and handover research. Key for maintaining cohesion between what learners hear and see.

🎙 Tone
~12

Tone & Register

Requests to shift from casual to semi-formal phrasing — including removal of second-person pronouns ("you"), overly colloquial language, and informal transitions unsuitable for eLearning narration.

📚 Content
~10

Content Gaps & Suggestions

Proactive recommendations to add missing information — such as proposing an additional taxonomy on food waste management alternatives, requesting definitions for technical terms, or suggesting more detailed explanations of key concepts.

✅ Positive
~5

Recognition & Standards-Setting

Deliberate positive feedback that acknowledged strong thesis statements and effective body slides — setting a benchmark for the entire document and reinforcing what "good" looks like.

Selected Comments with Rationale

The following examples demonstrate the depth and specificity of the QA feedback — not just what to fix, but why it matters for learner outcomes.

🏗

Structural / AREL Feedback

Repositioning information for better pedagogical flow

Importance Section — Cost-Saving Body Slide
"The idea in this section feels fragmented and would benefit from a clearer flow aligned with the AREL structure. Please clarify why and how managing food waste contributes to household cost savings to strengthen the argument. Add one concise, relevant study or data point to support the claim."
Why this matters: The AREL framework requires body slides to be argumentatively structured, not just informational. Without a clear "why" and "how," learners cannot connect evidence to the course objective.
Benefits Section — Healthy Diets Slide
"Please combine the highlighted information and place it in the body slide after the thesis statement slide. It would be great to focus on clearly explaining why managing food waste can support a healthier diet, especially in terms of food quality, nutrition, and daily eating habits. This will help make the flow smoother and strengthen the overall message."
Why this matters: Distributing information across the correct slide types prevents cognitive overload and ensures the thesis is explained before evidence is introduced.
Taxonomy Section — Taxonomy 1 Introduction
"I suggest to add information about different types of food waste management as an additional taxonomy for this course — it can be very useful for the learners and more aligned with the CO. I imagine this taxonomy is based on alternatives of food waste management after individuals classify food waste."
Why this matters: QA is not only corrective — it is also developmental. Identifying content gaps from the source material and proposing meaningful additions elevates the instructional quality beyond the first draft.
📖

Clarity & Readability Feedback

Making content accessible and voice-over ready

Misconception 1 — Body Slide
"Presenting each idea with its relevant study may cause choppy flow. One technique is to focus on synthesizing and combining the results of these studies to explain the thesis. Example: 'As the appearance of food becomes less appealing, the likelihood of it being discarded increases. People often associate unattractive food with lower quality...'"
Why this matters: Voice-over scripts must read naturally when spoken. Itemized study citations disrupt narrative flow. Synthesis-first writing is a core skill for eLearning script production.
Challenge 1 — Body Slide (Expiry Labels)
"This body slide feels like the Evidence slide of AREL to me. Prior to this slide, I suggest adding another slide after the thesis to further elaborate on it... I found relevant information from the handover that can be synthesized: 'Misunderstanding food date labels leads to household food waste, causing financial loss and environmental harm...'"
Why this matters: Providing suggested content from the source document removes ambiguity and demonstrates mastery of both the pedagogical framework and the subject matter.
🎙

Tone & Register Feedback

Maintaining semi-formal eLearning voice throughout

Misconception Section — General Comment
"This is a general comment about how we refer to our students that will take this course. Please stick with 'individual/people'. Using 'consumers' can be relevant when narrating the result of a study."
Why this matters: Consistent learner address terminology builds rapport and avoids confusion. QA must catch micro-level language decisions that designers may overlook under deadline pressure.
Importance Section — Environmental Impact Slide
"Please let's be consistent with the action verb related to the element. Since the CO uses the term 'dealing with food waste', please use these terms throughout the course. Alternatively, define 'dealing with food waste' in the ILMS definition part."
Why this matters: Terminological consistency is a hallmark of professional course design. Inconsistency creates cognitive friction and weakens the link between the learning objective and course content.

Positive Recognition

Setting the benchmark through affirmative feedback

Benefits Section — Healthy Diets Thesis Slide
"This is a really strong and clear thesis—great job, Samantha! It would be wonderful to see this same level of clarity and structure carried consistently throughout the rest of the AV script.."
Why this matters: Naming what "good" looks like is as important as flagging what's wrong. This comment creates a replicable standard and motivates the designer without imposing a prescriptive formula.
Importance Section — Body Slide (Cost Saving)
"EXCELLENT! This is what I want to see throughout the benefits section."
Why this matters: Brief, enthusiastic affirmation signals quality clearly. In a long review cycle, positive anchors help instructional designers calibrate their revisions correctly.
