Introduction

Duration: 15-20 minutes

Emotional Warmup Activity

Guided Deep Breathing

The suggested emotional warm-up activity is Guided Deep Breathing. This practice is designed to encourage focus, mindfulness, and concentration among students, mentally preparing them for the lesson ahead. Deep breathing is effective in calming the mind and body, easing anxiety, and enhancing mental clarity—crucial for solving math problems.

1. Ask students to sit comfortably in their chairs, keeping their backs straight and feet flat on the floor.

2. Instruct them to close their eyes and place their hands on their belly.

3. Explain that they should take a deep breath in through their nose, allowing their belly to rise and counting to four.

4. Ask them to hold their breath for a brief moment, counting to two.

5. Instruct students to exhale slowly through their mouth, fully emptying their lungs and counting to six.

6. Repeat this deep breathing cycle for five minutes, encouraging students to focus solely on their breathing.

7. After the activity, invite students to slowly open their eyes and stretch if needed.

Content Contextualization

At first glance, quadratic equations might seem tough, but they actually pop up in various situations in our daily lives. For instance, when we consider the path of an object thrown into the air, the design of a bridge, or even in economics when figuring out compound interest, we're dealing with quadratic equations. Grasping this mathematical concept enables us to tackle practical problems and make informed decisions across different aspects of life.

Moreover, working with quadratic equations cultivates logical and structured thinking—skills that are valuable not just in math, but in any scenario that requires problem-solving. By understanding and solving these equations, students also develop patience, persistence, and the ability to handle frustrations—key skills for personal and professional development.

Duration: 60-75 minutes

Theory Guide

Duration: 20-25 minutes

1. Definition of Quadratic Equation: A quadratic equation is a polynomial equation of degree two, which can be formulated as ax^2 = b, where a ≠ 0.

2. Coefficients: In the equation ax^2 = b, 'a' represents the coefficient of the quadratic term (x^2) and 'b' is the constant term.

3. Solving ax^2 = b: To solve this equation, the key step is isolating x^2. First, divide both sides by 'a' to get x^2 = b/a. Then, take the square root of both sides to discover the solutions for x.

4. Example 1: 2x^2 = 8 -> Dividing both sides by 2: x^2 = 4 -> Taking the square root: x = ±2

5. Example 2: 3x^2 = 27 -> Dividing both sides by 3: x^2 = 9 -> Taking the square root: x = ±3

6. Importance of Solutions: The solutions of a quadratic equation can be real or complex, depending on the values of 'a' and 'b'. For ax^2 = b with real and positive 'a' and 'b', the solutions will indeed be real.

7. Practical Applications: Discuss how quadratic equations show up in everyday contexts, like area computations, physics (parabolic motion), economics (supply and demand curves), among others.

8. Analogies to Facilitate Understanding: Compare solving a quadratic equation to piecing together a puzzle, where every piece (step) needs to fit together correctly to achieve the final solution (values of x).

Activity with Socioemotional Feedback

Duration: 35-40 minutes

Collaborative Solving of Quadratic Equations

This activity encourages students to work in pairs to solve a series of quadratic equations of the form ax^2 = b. The objective is to reinforce theoretical knowledge while also developing social-emotional competencies like teamwork, responsible decision-making, and emotional regulation.

1. Pair students up, encouraging them to select partners they don't usually work with.

2. Give each pair a list of quadratic equations of the form ax^2 = b to tackle together.

3. Encourage students to follow the problem-solving steps discussed in theory, working collaboratively and sharing ideas.

4. Have each pair record their solutions and the steps they used to reach those answers.

5. Once they've solved the equations, each pair will present one of their solutions to the class, explaining their process and any challenges they faced.

6. During the presentations, prompt the class to ask questions and offer constructive feedback.

Discussion and Group Feedback

After solving the equations, lead a group discussion utilizing the RULER method to guide socio-emotional feedback. Recognize: Ask students how they felt during the activity. Were there any moments of frustration or achievement? Understand: Help students pinpoint the reasons behind their emotions. For instance, frustration might stem from a tricky equation, while satisfaction may arise from successfully solving a problem. Name: Encourage students to label their feelings appropriately, such as anxiety, joy, frustration, or confidence. Express: Discuss constructive ways to express these feelings—whether it’s asking for help or celebrating small wins. Regulate: Invite students to share strategies they used to stay calm and focused, like deep breathing or breaking the problem into simpler parts. This reflection process fosters self-awareness and self-control, along with better collaboration and social awareness.

Conclusion

Duration: 20 - 25 minutes

Reflection and Emotional Regulation

Encourage students to write a brief reflection on the challenges they encountered while solving quadratic equations. Prompt them to describe their feelings at different stages of the lesson and how they coped with both positive and negative emotions. Alternatively, facilitate a group discussion where each student shares their experiences and the strategies they employed to handle frustrations and celebrate triumphs.

Objective: The goal of this activity is to promote self-reflection and emotional regulation, helping students identify effective coping strategies for dealing with tough situations. By contemplating their feelings and actions, students can enhance their self-awareness and self-control, vital skills for lifelong learning and day-to-day interactions.

Glimpse into the Future

Emphasize the importance of setting personal and academic goals for ongoing growth. Invite each student to set a goal related to the lesson material, such as solving a quadratic equation on their own or assisting a classmate in understanding the concept. Encourage them to think about realistic short-term goals that will contribute to their personal and academic journeys.

Penetapan Objective:

1. Independently solve a quadratic equation.

2. Assist a classmate in understanding and solving a quadratic equation.

3. Practice solving quadratic equations daily for a week.

4. Identify and apply a new strategy for managing frustrations during math problem-solving.

5. Actively engage in group discussions about solving quadratic equations. Objective: This part aims to empower students with autonomy and practical application of their learning. By setting personal and academic goals, students are motivated to continue honing their math skills and developing their socio-emotional competencies, facilitating ongoing and meaningful learning.
