They will tackle challenges relating to optical isomers and chiral carbons to progress through the game. The objective is to comprehend the concepts through a gamified and collaborative approach.

- Instructions:

• Divide the class into groups of up to 5 students.

• Indicate a specific online educational game that simulates challenges of optical isomerism (e.g., ChemCollective, the 'Isomer Maze' game).

• Each group should register and collaborate while playing, discussing answers and strategies to complete the challenges.

• As they progress, they should take note of the most challenging questions and how they approached solving them.

• At the end, each group will summarize their key learnings and share advice for overcoming the challenges.

Activity 3 - 📱 Science in Action: Optical Isomerism and Augmented Reality

- Instructions:

• Divide the class into groups of up to 5 students.

• Guide students to download a chemistry AR app (e.g., Molecule Viewer AR) on their phones.

• Each group will employ the app to visualize 3D models of optical isomers and examine different spatial arrangements.

• Students will create a video where they explain the concept of chiral carbon, methods for identifying optical isomers, and their properties.

• Videos should be shared on a platform of the teacher's choice for everyone to view and comment.

Feedback

Duration: 20 - 25 minutes

The purpose of this stage is to encourage critical and constructive reflection on the activities undertaken, promoting collaborative learning and continuous improvement. Through group discussions and 360° feedback, students gain the opportunity to share their insights, learn from their peers' approaches, and receive specific guidance to enhance their understanding of optical isomerism.

Group Discussion

Facilitate a group discussion where all students share what they learned from the activities and their conclusions. Use the following script to introduce the discussion:

1. Introduction: 'Now that everyone has completed their activities, let's share our discoveries and thoughts. Each group will have about 5 minutes to present their work and key learnings.'
2. Sharing: 'Please start by presenting your created content, clarifying the major points about optical isomerism and the significance of chiral carbons.'
3. Discussion: 'After each presentation, other groups can pose questions and provide constructive feedback. Let's focus on how each group approached the topic and what insights we can gain from each other's experiences.'
4. Conclusion: 'To wrap up, let's consider how these activities improved our understanding of optical isomerism and its real-world applications.'

Reflections

1. What was the greatest challenge you faced while creating content about optical isomerism? How did you navigate this obstacle? 2. What aspect of the practical applications of optical isomerism stood out the most for you? Why was it significant? 3. How did the incorporation of technology (augmented reality, social media, gamification) aid in your comprehension of the concepts discussed?

Feedback 360º

Encourage students to engage in a 360° feedback session, where each student will receive reflections from their peers in their group. Guide the class to follow these rules for constructive and respectful feedback:

1. Be Specific: 'When providing feedback, zero in on particular aspects of the work and behavior. For instance, 'I appreciated how you clarified the concept of chiral carbon with a clear analogy.''
2. Be Positive and Constructive: 'Begin with positive feedback and mention areas for improvement in a constructive way. Example: 'You did a fantastic job editing the video. Perhaps next time, you could include more practical illustrations.''
3. Be Respectful: 'Honor your peers' opinions and feelings. The goal is to aid in everyone's growth, not to offer destructive criticism.'

After the session, ask students to reflect on the feedback received and how they can use these suggestions in their future projects.
