Minister Chan Chun Sing’s interview highlighted several key shifts in Singapore’s education system that directly affect students. These changes aim to reduce academic stress, promote diverse strengths, and encourage lifelong learning. Here’s how students are impacted:

---

1. More Personalized Learning Experiences

• The introduction of Full Subject-Based Banding (FSBB) allows students to take subjects at different difficulty levels based on their strengths.
  • Impact:
    • Students are no longer limited by their overall academic performance—they can excel in subjects they are strong in while receiving extra support in weaker subjects.
    • Encourages students to focus on their individual strengths instead of trying to be good at everything.
    • Reduces the stigma associated with weaker subject performance, fostering a more inclusive learning environment.

---

2. Shift in Academic Culture: Less Stress, More Holistic Development

• Policies like “Learn More, Test Less” and the revamp of the PSLE scoring system aim to reduce unnecessary academic pressure.
  • Impact:
    • Students are no longer judged on a fine-grained numerical ranking but on broader achievement bands, reducing unhealthy competition.
    • More focus on developing soft skills, creativity, and problem-solving instead of just rote memorization.
    • However, some students and parents may still feel pressure to excel in other ways, such as through Direct School Admission (DSA) or co-curricular activities (CCAs).

---

3. Greater Exposure to a Diverse Peer Group

• FSBB mixes students of different academic abilities in the same class for common subjects.
  • Impact:
    • Students interact with a more diverse range of peers, promoting mutual respect and reducing social stratification based on academic results.
    • Encourages a collaborative, inclusive mindset rather than a “top vs. bottom” mentality.

---

4. More Independent and Self-Directed Learning

• Schools are incorporating technology and AI-driven learning tools, similar to gamification in video games.
  • Impact:
    • Students have access to personalized, AI-driven resources that adapt to their individual learning pace.
    • Encourages self-directed learning, preparing students for university and lifelong learning.
    • However, students must develop good time management skills as some learning models involve self-paced study with gaps in their school schedules.

---

5. Changing Definition of Success

• There is a stronger push for students to discover and play to their strengths rather than comparing themselves to others.
  • Impact:
    • Students are encouraged to develop a growth mindset, understanding that different people have different talents.
    • Less focus on relative performance (i.e., “Am I better than my peers?”) and more on individual progress (i.e., “How can I improve myself?”).
    • However, shifting away from a grade-centric mindset is still a work in progress, and some students may struggle with the transition.

---

6. More Career-Focused and Real-World Learning Opportunities

• Universities and polytechnics are emphasizing lifelong learning and skills-based education.
  • Impact:
    • Students are better prepared for real-world job expectations, as universities focus on skills like problem-solving, collaboration, and innovation.
    • More opportunities for internships, hands-on learning, and career-relevant projects.
    • Less emphasis on pure academic results in university admissions and job hiring—employers are looking for well-rounded graduates.

---

7. Tuition May Become Less Necessary for Some, But Shift in Focus for Others

• With more personalized and accessible school resources, some students may rely less on tuition.
  • Impact:
    • Students who struggle with certain subjects can get school-based support rather than depending on external tuition.
    • For high-achieving students, tuition may shift towards enrichment rather than remedial help(e.g., leadership programs, coding courses, entrepreneurship training).
    • Parental pressure may still exist, pushing students to pursue additional tuition in areas like CCAs, DSA prep, and interview coaching instead of just academics.

---

Conclusion: A More Flexible, Student-Centered Education System

• Positive Impact:
  • Students can learn at their own pace and focus on their strengths.
  • Less stress from high-stakes exams and competition.
  • More diverse and inclusive learning environments.
  • Stronger emphasis on lifelong learning and career readiness.
• Challenges:
  • Cultural shifts take time—some students and parents still feel pressure to “stand out” in other ways.
  • Increased independence means students need self-discipline and time management skills.
  • Some students may struggle with adapting to less structured learning environments.

Final Thoughts

Overall, the changes in Singapore’s education system aim to create well-rounded, lifelong learners rather than just top scorers. However, students will need to adapt to a less rigid, more self-directed learning culture.

Minister Chan Chun Sing’s interview highlighted several key aspects of how Singapore’s evolving education policies impact the tuition industry. Below are the main points:

---

1. Reduced Academic Stress Could Affect Tuition Demand

• The shift towards full subject-based banding (FSBB) and broader assessment methods (beyond just exam scores) aims to reduce excessive academic stress.
• By discouraging unhealthy competition and over-reliance on grades, there may be less pressure on parents to enroll their children in tuition classes.
• However, parents may redirect their focus to non-academic differentiators like Direct School Admission (DSA), co-curricular activities (CCAs), and enrichment programs.

---

2. Tuition Industry Quickly Adapts to Policy Changes

• Tuition centers adjust their marketing strategies in response to MOE’s initiatives.
  • Example: When FSBB was introduced, tuition centers rebranded their services to help students cope with taking different subjects at different difficulty levels.
  • Similarly, after MOE reformed the Gifted Education Program (GEP), tuition centers expanded their preparatory courses to target multiple entry points, despite MOE’s intent to reduce stress.
• Minister Chan criticized tuition centers that exploit parental anxiety, using tactics like guilt-tripping parents into signing up their children for extra classes.

---

3. Technology & Mass Customization May Reduce the Need for Tuition

• MOE is leveraging AI, data analytics, and online learning resources to provide more personalized education.
• Examples include:
  • AI-powered essay feedback systems in schools.
  • Online personalized math exercises that adjust to students’ learning levels.
• These initiatives could reduce dependence on tuition for remedial or advanced learning.

---

4. Possible Regulation of Tuition Advertising & Practices

• Some tuition centers:
  • Pre-select top students and claim credit for their success.
  • Use misleading marketing tactics to suggest that tuition is essential for academic excellence.
• MOE is in discussions with advertising regulators to establish ethical guidelines for tuition industry marketing.

---

5. Private Tuition May Go Underground if Over-Regulated

• Some countries have banned excessive private tuition, but this has led to an underground tuition industrywhere only the wealthy can afford elite private tutors.
• Singapore is unlikely to ban tuition but aims to reduce over-reliance by improving public education accessibility.

---

Conclusion: Tuition Industry Will Adapt, But Its Role May Shift

• While tuition will not disappear, demand for traditional rote-learning-based tuition may decline.
• The industry might shift focus to:
  • Skills-based and enrichment programs.
  • Preparing students for non-academic pathways like DSA and CCAs.
  • Providing support for students with special needs or weak subjects.
• MOE’s success in promoting lifelong learning and reducing academic pressure will determine whether tuition remains a necessity or becomes a supplementary choice.

To understand principal values of inverse trigonometric functions, let’s break it down step by step:

1. Why Do We Need Inverse Trig Functions?

Trigonometric functions (like \( \sin \theta \), \( \cos \theta \), \( \tan \theta \)) take an angle and give a number. Inverse trig functions (like \(\sin^{-1} x\), \(\cos^{-1} x \), \(\tan^{-1} x \)) do the opposite: they take a number and return an angle.

2. The Problem: Periodicity

Trig functions are periodic, meaning they repeat their values. For example:

• \( \sin 30^\circ = \sin 150^\circ = 0.5 \)
• \( \cos 0^\circ = \cos 360^\circ = 1 \)

This means there are infinitely many angles that give the same trig value. But a function can only have one output for each input. So, how do we define inverse trig functions?

3. Solution: Restrict the Domain (Principal Values)

To make inverse trig functions work, we restrict their range (the angles they can output) to a specific interval called the principal value. This ensures each input gives exactly one angle.

Principal Value Ranges:

Function	Principal Value Range	Why?
\( \sin^{-1}x \)	\([- \frac{\pi}{2}, \frac{\pi}{2}] \)	Covers all outputs from \(-1 \) to \(1 \) and is centred around 0.
\( \cos^{-1}x \)	\([0, \pi] \)	Covers all outputs from \(-1 \) to \(1 \) and includes all quadrants.
\( \tan^{-1}x \)	\( (- \frac{\pi}{2}, \frac{\pi}{2}) \)	Avoids vertical asymptotes and covers all real numbers.

4. Key Takeaways

• Principal values are the “main” angles returned by inverse trig functions.
• Calculators use these ranges to give a single answer (e.g., typing \( \sin^{-1}(0.5) \) gives \( \frac{\pi}{6} \)).

Express \( \frac{(x+2)^2}{x^2(x-2)} \) as the sum of 3 partial fractions.

Take note that \( x^2 \) is a repeated factor

\( \begin{aligned} \frac{(x+2)^2}{x^2(x-2)}=\frac{x^2+4 x+4}{x^2(x-2)} \\ \text { Let } \frac{x^2+4 x+4}{x^2(x-2)} =\frac{A}{x}+\frac{B}{x^2}+\frac{C}{x-2} \\ \quad x^2+4 x+4 =A x(x-2)+B(x-2)+C x^2\end{aligned}\)

Find values of \( A \) and \( B \) by substituting suitable values of \( x \)

To find \( B \), sub \( x = 0 \)

To find \( C \), sub \( x = 2 \)

Now that we know \( B \) and \( C \), sub \( x = 1 \) to find \( A \)

(i) Find the value of \(a\) and of \(b\) for which \(2 x^2+3 x-2\) is a factor of \( 2 x^4+3 x^3+a\left(x^2+x\right)+b \)

(ii) Using the values of \(a\) and \(b\) found in part (i), solve the equation \(2 x^4+3 x^3+a\left(x^2+x\right)+b=0 \)

(i) If \(2 x^2+3 x-2\) is a factor of \( 2 x^4+3 x^3+a\left(x^2+x\right)+b \), the factors of \(2 x^2+3 x-2\) are also factors of \( 2 x^4+3 x^3+a\left(x^2+x\right)+b \)

Factorise \(2 x^2+3 x-2\) to get \( (2x-1)(x+2) \)

Apply factor theorem

Let \( f(x) = 2 x^4+3 x^3+a\left(x^2+x\right)+b \) ,

\( f(0.5) =0 \) , since \( (2x-1) \) is a factor

\( 2 + 3a +4b = 0 \)

\( f(-2) =0 \) , since \( (x+2) \) is a factor

\( 8 + 2a + b = 0 \)

Solving simultaneously, \(a = – 6 \), \( b = 4 \)

(ii) To solve \(2 x^4+3 x^3-6\left(x^2+x\right)+4=0 \)

Perform long division

The quotient of \( \left(2x^4 +3x^3 −6(x^2+x)+4 \right) \div \left(2x^2+3x−2 \right)\) is:\(x^2−2 \)

Hence \( \left(2x^2+3x−2 \right) \left(x^2−2 \right) = 0 \)
