DIAGNOSTIC ASSESSMENT

DATA ANALYSIS & CRITICAL THINKING

CANDIDATE NAME:

DATE OF ASSESSMENT:

Instructions for the Candidate:
This assessment contains two sections designed to evaluate your ability to analyze quantitative data and formulate structured, abstract arguments, similar to the tasks in the IELTS Writing section. Read all instructions and source materials carefully. Write your answers clearly in the spaces provided.

SECTION 1: The Data Scientist's Mission (IELTS Writing Task 1 Style)

CONTEXT: The table below displays public satisfaction ratings for two new urban developments in 2025. The data represents the percentage of positive responses from a public survey across three key criteria.

Public Satisfaction Ratings for New Urban Developments (2025)

Percentage of Positive Responses

Criterion	Harbourfront Oasis	Skygardens Residence
Cost	45%	60%
Green Space	80%	75%
Transport Links	85%	55%

IELTS Task 1 Instruction: Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

Part A: Analyse the Data (The "Quantitative" Mission)

Your mission is to act as a data scientist. You do not give opinions; you report the facts locked inside the numbers with precision.

Identify the single highest satisfaction rating shown on the chart (i.e., which development and for which criterion).
Identify the single lowest satisfaction rating shown on the chart.
Identify the criterion with the biggest difference in satisfaction ratings between the two developments.
Write a single "overview" sentence (approx. 20-30 words) that summarises the most important trend or contrast shown in the data.

Part B: Structure the Report (The "Data-First" Template for IELTS Task 1)

Create a point-form outline for a report summarizing this data. Do NOT write full sentences for the body paragraphs; just state the key facts you would include. This outline helps you structure your thoughts, mirroring the planning phase for a full IELTS Task 1 report.

Introduction:
- Your overview sentence from Part A.
Body Paragraph 1 (Focus on Harbourfront Oasis):
- Key Feature 1 (e.g., its highest-rated aspect).
- Key Feature 2 (e.g., its lowest-rated aspect).
Body Paragraph 2 (Focus on Skygardens & Comparison):
- Key Feature 1 (e.g., its highest-rated aspect).
- A comparative statement (e.g., how it directly contrasts with Harbourfront Oasis in a specific area).

SECTION 2: The Critical Thinker's Matrix (IELTS Writing Task 2 Style)

TASK: This section tests your ability to analyse complex, abstract ideas. Do NOT write a full answer. Instead, use the provided framework to plan the core components of an answer to the following prompt.

IELTS Task 2 Prompt: "To what extent should the cultural heritage of a location influence the design of new buildings? Present a clear argument and support it with relevant reasons."

Part A: The 'Research' Mode (Analyse the 'WHY')

First, demonstrate your ability to think like a researcher by exploring the complexity of the question. In one sentence, acknowledge the two sides of the issue. (This forms the foundation of a balanced introduction, similar to IELTS Task 2).

Part B: The 'Design' Mode (Propose the 'HOW')

Now, pivot to your own "design"—your personal, decisive opinion. In one sentence, state your view clearly. (This is your thesis statement, crucial for IELTS Task 2).

Part C: The 'Justification' (Your Rationale)

Every strong opinion needs a rationale. Justify your Part B sentence by adding a "because" clause, explaining why you hold that view. (This outlines your core argument, demonstrating the depth of your critical thinking).

SECTION 1: MODEL ANSWERS

Part A: Analyse the Data

Highest Rating: Harbourfront Oasis for Transport Links (85%).
Lowest Rating: Harbourfront Oasis for Cost (45%).
Biggest Difference: Transport Links (a 30-percentage-point difference).
Overview Sentence: Overall, while Harbourfront Oasis received higher public satisfaction for its Green Space and particularly its Transport Links, Skygardens Residence was rated more favourably for its cost.

Part B: Structure the Report

Introduction:
- Overall, while Harbourfront Oasis received higher public satisfaction for its Green Space and particularly its Transport Links, Skygardens Residence was rated more favourably for its cost.
Body Paragraph 1 (Focus on Harbourfront Oasis):
- Highest rating was for Transport Links at 85%.
- Lowest rating was for Cost at only 45%.
Body Paragraph 2 (Focus on Skygardens & Comparison):
- Most popular feature was Green Space (75%).
- In direct contrast to Harbourfront Oasis, its rating for Transport Links was significantly lower at 55%.

SECTION 2: MODEL ANSWERS

Part A: The 'Research' Mode

While some argue that cultural heritage should strongly dictate new architectural designs to preserve identity, others contend that modern designs should prioritize functionality, sustainability, or global aesthetics.

Part B: The 'Design' Mode

Cultural heritage should significantly influence new building designs, but not at the expense of innovative architectural solutions.

Part C: The 'Justification'

...because integrating heritage respectfully creates a sense of continuity and belonging, enhancing the community's connection to its past while allowing for contemporary evolution.

SECTION 3: TEACHER-FACING ANALYSIS & PROFILING NOTES

1. Knowledge Points & Curriculum Links:

Quantitative Reporting (Curriculum Block D3) & IELTS Academic Writing Task 1: This is a direct test of the student's ability to engage in objective, quantitative analysis and structure a report. It assesses whether they understand that their role is to report, not interpret or give opinions, a core requirement for Task 1.
Pattern Recognition & Data Selection (Module 2): Can the student move beyond individual data points to see the bigger picture? Their choice of what to include in the overview and body paragraphs reveals their ability to identify "key" features, a core IELTS Task 1 skill.
Comparative Language (Module 2): The task design forces a comparison between the two developments, testing their ability to structure a comparative analysis rather than just a simple description.
Task 1 Report Structure (C1): Evaluates their understanding of the conventional Task 1 structure: Overview, followed by logically grouped details.
Critical Argumentation (Architecture & IELTS Academic Writing Task 2): This assesses the student's ability to analyze a complex prompt, identify different perspectives, form a clear personal opinion (thesis), and provide a concise justification, which are fundamental skills for IELTS Task 2 and architectural discourse.

2. Dissection of Student Logic & Thought Patterns:

Holistic vs. Detail-Oriented (Section 1): Does the student immediately see the main contrast (e.g., Oasis is good for transport, Skygardens is good for cost) and use that to frame their analysis? This is a holistic, top-down approach. A detail-oriented or bottom-up thinker might start by listing all the percentages and struggle to formulate a clear overview.
Comparative vs. Sequential Thinker (Section 1): In Part B, does the student naturally structure their second paragraph around a point of comparison ("In contrast to...")? Or do they just describe Skygardens in isolation, as if it were a separate chart? The former shows a higher-level analytical skill required for a high score.
Data Selection Priority (Section 1): What does the student identify as the most important information? The highest and lowest values are the most obvious. A more perceptive student will also spot the largest gap between the two developments (Transport Links) as a key feature worth mentioning.
Process Speed & Confidence (Section 1): Is the data extraction in Part A quick and accurate? Hesitation or errors here can signal a lack of confidence or experience with chart reading, which is a foundational skill.
Argumentative Structure vs. Opinion Presentation (Section 2): Does the student identify the need to acknowledge complexity before stating their own view? This indicates understanding of a balanced argumentative essay structure, crucial for IELTS Task 2. A weaker student might jump directly to their opinion without acknowledging nuance.
Depth of Justification (Section 2): How logically sound and specific is their 'because' clause? Does it offer a superficial reason or delve into a more profound implication related to cultural preservation, modernism, or community identity? This reflects their ability to construct a reasoned argument.

3. Common Hurdles & Anticipated Errors:

Error in Part A.4 (Weak Overview - Section 1): The most common error. The student writes an overview that is just a list of facts (e.g., "The chart shows ratings for Cost, Green Space, and Transport.") instead of a summary of the main trend (e.g., "Overall, the developments showed contrasting strengths...").
Error: Injecting Opinion (Section 1): The student adds their own thoughts, such as "The 45% for Cost is very bad because Hong Kong is expensive." This shows they have not grasped the objective nature of the task.
Error: "Number Dumping" (Section 1): In the Part B outline, the student plans to just list all six numbers without any logical grouping or sense of priority. This reveals a failure to synthesise the data.
Error: Inaccurate Comparisons (Section 1): The student might say "Skygardens has better Green Space," which is factually incorrect (80% vs 75%). This tests attention to detail.
Error: Unbalanced Opinion (Section 2): The student immediately takes a strong stance without acknowledging the complexity of the 'To what extent' prompt, which is common in IELTS Task 2 if not trained to present a balanced view.
Error: Vague Justification (Section 2): The 'because' clause is too general or relies on emotion rather than a logical principle (e.g., 'because it just looks better' or 'because culture is important').

SECTION 4: PROFILING RUBRIC

Dimension	Level 3: Perceptive Analyst	Level 2: Systematic Reporter	Level 1: Data Lister
1. Data Interpretation (Accuracy & Selection - Section 1)	Identifies not just the highest/lowest points but also the most significant comparison or contrast. The overview is a sophisticated summary of the data's main "story."	Accurately identifies the key data points (highs, lows). The overview is correct but may be a simple, mechanical summary of the main features rather than a true synthesis.	Makes errors in reading the data or selects less significant points to focus on. The overview is weak, often just rephrasing the title of the chart without summarizing the findings.
2. Structural Logic (Systematic Thinking - Section 1)	Creates a highly logical outline that groups data for clear comparison (e.g., groups by development, highlights a key contrast). The structure is designed to make the data easy to understand.	Creates a functional and correct outline. The structure is logical (e.g., Intro, Body 1, Body 2) but the grouping of data may be less effective for comparison than a Level 3 approach.	The outline is disorganized or simply lists data points in the order they appear on the chart. There is no clear logical grouping or attempt to structure an argument.
3. Language of Objectivity (Vocabulary - Section 1)	The overview sentence uses precise, neutral, and comparative language (e.g., "in stark contrast," "while the former excelled in..."). Demonstrates mastery of the quantitative reporting tone.	The overview sentence is factually correct and objective. The language is simple and clear but may lack the sophisticated comparative vocabulary of a Level 3 analyst.	The language used in the plan or overview is subjective ("is very good," "is disappointingly low") or is vague and imprecise. Fails to adopt the required analytical tone.
4. Critical Argumentation (IELTS Task 2 Prep - Section 2)	Acknowledges complexity succinctly, states a clear, nuanced opinion, and provides a concise, principle-based justification, demonstrating readiness for an extended essay.	Aknowledges different views but may not integrate them smoothly. States a clear opinion but the justification might be somewhat broad or less deeply reasoned.	Jumps to opinion immediately without acknowledging complexity. The opinion may be unclear, and the justification superficial or missing a clear logical link.
