Activity Suggestions

Activity Recommendations

Activity 1 - The Journey of the Digital Influencer 📈

> Duration: 60 - 70 minutes

- Goal: Apply concepts of geometric progression in relatable and practical contexts, fostering comprehension through an engaging digital approach.

- Deskripsi Activity: Learners will simulate the follower growth of a digital influencer using geometric progression. The activity consists of creating a timeline that illustrates the exponential growth of followers over a number of weeks.

- Instructions:

• Divide the learners into groups of up to 5 members.

• Each group must select a fictional 'digital influencer' to represent for the activity.

• Groups should create a social media profile for the influencer using a digital tool like Canva or a hypothetical Instagram account.

• They'll need to determine a geometric progression formula to model follower growth. For example, if the ratio is 2, with an initial 10 followers, the sequence would be 10, 20, 40, 80, etc.

• Learners must create a visual timeline showcasing the influencer's growth over the weeks, using graphs and digital presentations.

• Each group will present its timeline and explain how they applied geometric progression to calculate the follower growth.

Activity 2 - Unpacking the World of Viral Videos 🎥

> Duration: 60 - 70 minutes

- Goal: Develop skills in calculating geometric progressions and applying this understanding to real-world scenarios of exponential growth within the digital platform.

- Deskripsi Activity: Learners will examine the growth of views on a viral video online, using geometric progression to project view counts over time.

- Instructions:

• Split the learners into groups of up to 5 members.

• Each group should choose a recent viral video (they can use their social media or platforms like YouTube).

• Learners need to find initial view data and identify a daily growth rate.

• Using the growth ratio discovered, they will calculate the predicted view count for the upcoming days, weeks, or months with the geometric progression formula.

• Groups must present their forecasts in the form of graphs, tables, or digital presentations, explaining their calculations and the reasoning behind them.

• If possible, groups can compare their predictions with actual data to validate their calculations.

Activity 3 - Gamification: The Race of Numbers 🚀

> Duration: 60 - 70 minutes

- Goal: Foster collaboration, a spirit of friendly competition, and the practical application of geometric progression concepts through a gamified experience.

- Deskripsi Activity: Learners will engage in a gamified competition, tackling challenges related to geometric progressions to advance in the game.

- Instructions:

• Divide the learners into groups of up to 5 members.

• Explain the game rules: each correctly solved challenge allows the group to move up one 'level' in the competition.

• Present a set of challenges involving geometric progressions, such as determining the nth term of a given sequence or finding the ratio of a specified GP.

• Learners will use their devices to tackle the challenges and submit their answers via a digital platform, like Google Forms or Kahoot.

• With each level, the challenges increase in difficulty, promoting collaboration and critical thinking.

• At the end, the group that completes the most levels is declared the winner and can receive a small token prize.

Feedback

Duration: (15 - 20 minutes)

This stage is designed to encourage in-depth reflection on the activities undertaken, allowing learners to consolidate their understanding and benefit from shared perspectives. The group discussion and 360° feedback encourage critical thought, collaboration, and the development of interpersonal skills, which are vital both academically and in the digital landscape.

Group Discussion

Encourage a whole-class discussion where groups reflect on what they learned during the activities and share their insights. To guide this discussion, follow a brief outline:

1. Start: Begin by thanking everyone for their participation and commending the groups for their efforts.
2. Sharing: Invite each group to present a brief overview of their activities, emphasizing the key challenges and conclusions drawn.
3. Interaction: Motivate students to ask questions of each other, fostering an environment conducive to sharing ideas and reflections.

What could have led to those variations?

Feedback 360º

Guide the class to engage in a 360° feedback session, where each learner should receive feedback from their group members. Offer these guidelines to ensure constructive and respectful feedback:

1. Respect: Remind learners of the importance of maintaining respect during the feedback exchange.
2. Specificity: Encourage students to be specific in their comments, addressing both strengths and areas for improvement.
3. Constructiveness: Instruct that the feedback should be constructive, focusing on how peers might enhance their skills and future collaborations.
