This stage aims to provide a hands-on, interactive opportunity for students to apply the concepts of independent event probability in scenarios relevant to their lives. Group collaboration cultivates teamwork, critical thinking, and creative use of technology.

Activity Suggestions

Activity Recommendations

Activity 1 - Social Media Roulette 🎰

> Duration: 60 to 70 minutes

- Goal: Understand and calculate the probability of independent events through a relatable scenario involving social media influencers.

- Deskripsi Activity: In this activity, students will explore independent events' probabilities using a digital roulette on social media. They will design a roulette featuring various challenges a digital influencer might encounter, such as reposting a story or liking a post. Using free roulette apps, they'll define the events and calculate the probabilities of the outcomes.

- Instructions:

• Group students into teams of up to 5.

• Have the groups select a digital roulette app, like 'Spin The Wheel' or something similar.

• Each group creates a digital roulette with 6 to 8 potential actions a digital influencer might take (e.g., posting a photo, liking a post, going live, etc.).

• Groups should spin the roulette twice and note the results.

• Students need to compute the probability of each combination of occurrences, treating them as independent events.

• Each group must prepare a short presentation (using Google Slides) to explain their calculations and findings.

Activity 2 - The Dice Challenge 🎲

> Duration: 60 to 70 minutes

- Goal: Explore the practical implications of the probability of independent events through dice experiments and theory comparison.

- Deskripsi Activity: Using virtual dice from various apps, students will perform experiments involving dice rolls to delve into the probability of independent events. They will assess potential outcomes and calculate the probability of achieving specific results in consecutive rolls, comparing these to theoretical probability.

- Instructions:

• Split students into groups of up to 5.

• Instruct each group to download a virtual dice rolling app, like 'Dice Roller' or similar.

• Groups must carry out 30 pairs of rolls using the virtual dice, recording each roll's results.

• Students will compute the observed frequency of results and compare it to the theoretical probability, discussing any discrepancies.

• Each group should prepare a digital report (using Google Docs) showcasing their calculations, frequency charts, and analysis of the differences found.

• Groups must share their reports with the entire class via a digital platform like Google Classroom.

Activity 3 - Interactive Probability Stories 📖

> Duration: 60 to 70 minutes

- Goal: Implement the concept of independent event probability through interactive storytelling, fostering critical analysis and fun contextualization.

- Deskripsi Activity: Students will craft interactive stories using the digital platform 'StoryLab'. Each narrative must incorporate decision points where characters face independent probabilistic events. The class should collectively discuss the probabilities linked to each decision and how it shapes the story's outcome.

- Instructions:

• Form teams of up to 5 students.

• Guide each group to access 'StoryLab' to construct their interactive tale.

• Each group must create a story with at least three decision points featuring independent events (e.g., selecting paths in a forest where each option boasts a different likelihood of encountering diverse animals).

• Students will calculate and debate the probabilities of each independent event related to their choices.

• Groups must share the link to their interactive story with the class, allowing everyone to experience their peers' narratives.

• Each group should then present a brief analysis of the different narrative branches and their associated probabilities.

Feedback

Duration: 20 to 25 minutes

This stage is designed to consolidate learning through reflection and an exchange of experiences. Group discussions enable students to share their insights, reinforcing learned concepts. The 360° feedback process enhances interpersonal and collaborative skills, crucial for success in both academics and professional settings.

Group Discussion

Once the activities are wrapped up, steer a group discussion with all students. Use the following outline to ignite the conversation:

1. Kick-off: Ask students about their experiences using digital tools to calculate probabilities regarding independent events.
2. Results Sharing: Invite each group to summarise their findings, emphasizing key challenges and breakthroughs.
3. Comparison and Analysis: Encourage students to contrast methods and results from different groups, discussing possible reasons for observed variations.
4. Wrap-up: Prompt students to contemplate how probability concepts might be relevant in other aspects of their lives and studies.

Reflections

1. What were the main hurdles you encountered while calculating the probability of independent events? 2. How do you envision applying the concepts learned in real-life scenarios? 3. Did using digital tools enhance your understanding of independent events? Why or why not?

Feedback 360º

Instruct students to participate in a 360° feedback session where each learner receives insights from fellow group members. Highlight the importance of constructive and respectful critique. Guide students to adhere to this feedback structure:

1. Strengths: Recognise what went well in the peer's work and teamwork.
2. Improvement Areas: Point out where the peer could advance their skills or approaches.
3. Thanks: Express gratitude for their contributions during the activity, reinforcing the value of collaboration.
