Introduction

Duration: 10 to 15 minutes

The purpose of this stage of the lesson plan is to provide an engaging and interactive start that connects students to the topic in a dynamic and digital way. By encouraging the use of cell phones to search for information and share interesting facts, students become the protagonists of their own learning, introducing the theme in a contextualized manner with the digital reality they live in.

Warming Up

Explain to the students that today we will explore the concept of linkage in genetics, something they have already studied at home. Linkage refers to genes that are located close to each other on the same chromosome and therefore tend to be inherited together. Ask the students to use their cell phones to find an interesting fact about genetic linkage, such as a specific example of linkage in plants or animals, and share it with the class.

Initial Reflections

1. What is linkage and why is it important in genetic transmission?

2. How does linkage differ from independent assortment?

3. What are some examples of linkage in living organisms?

4. How can linkage affect the expected outcomes in a genetic cross?

5. What modern tools are used to study linked genes?

Development

Duration: 70 to 80 minutes

The purpose of this stage of the lesson plan is to deeply and practically engage students with the concept of linkage in genetics. By working in groups to solve complex problems and create digital content, students apply their knowledge creatively and collaboratively, contextualizing their learning in the modern digital environment they experience.

Activity Suggestions

It is recommended that only one of the suggested activities be carried out

Activity 1 - Genetic Detectives in Action

> Duration: 60 to 70 minutes

- Objective: Apply the concept of linkage and solve genetic problems in a practical and collaborative manner.

- Description: Students will be challenged to solve a 'genetic crime' using their skills in understanding the concept of linkage. They will work in groups to analyze a series of digital clues and find the relationship between linked genes that led to a specific biological 'crime'.

- Instructions:

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

• Provide each group with a fictional genetic crime case available on an online platform (Google Classroom, for example).

• Each case will contain a series of digital clues, such as images of chromosomes, genetic crossing data, and genetic reports.

• Groups must use this data to identify which genes are linked and how this influenced the outcome of the 'crime'.

• Students must create a digital report detailing how they reached the conclusion, including diagrams and justifications based on linkage.

• Groups will present their conclusions to the class using digital tools such as slides or infographics.

Activity 2 - Digital Influencers of Genetics

> Duration: 60 to 70 minutes

- Objective: Communicate complex scientific concepts in an accessible and engaging way, using social media as an educational tool.

- Description: Students will transform into 'digital influencers' specialized in genetics. They will create posts for social media (simulated) explaining the concept of linkage and its importance in an attractive and informative way.

- Instructions:

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

• Guide students to choose a popular social network (Instagram, TikTok, etc.) and a post format (short video, infographic, image carousel).

• Each group must create content explaining the concept of linkage, types of linkage, and examples in nature, using accessible language and attractive visuals.

• Students can use editing and graphic design apps (such as Canva) to create the posts.

• After completing, groups must present their posts to the class, simulating a scientific outreach campaign.

• Promote a vote among students to elect the best 'digital influencer of genetics' based on clarity, creativity, and scientific accuracy.

Activity 3 - Genetic Gamification: Digital Escape Room

> Duration: 60 to 70 minutes

- Objective: Reinforce the understanding of the concept of linkage through problem-solving and gamification, promoting collaboration and critical thinking.

- Description: Students will participate in a digital escape room themed around genetics and linkage. They will need to solve a series of puzzles and challenges related to the topic to 'escape' the virtual environment.

- Instructions:

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

• Set up a digital escape room using a platform like Google Forms or a gamification tool (Genially or Classcraft).

• Each group must access the digital escape room and solve challenges involving linkage diagrams, genetic crossings, and data interpretation.

• Each puzzle solved will provide a clue for the next challenge until students can 'escape'.

• Establish a timer to add an element of urgency and friendly competition.

• At the end, promote a discussion about the strategies used and revisit the linkage concepts explored during the activity.

Feedback

Duration: 15 to 20 minutes

The purpose of this stage of the lesson plan is to consolidate learning, promote critical reflection on the activities carried out, and strengthen the sense of community and collaboration among students. By sharing their experiences and receiving constructive feedback, students have the opportunity to deepen their understanding of the topic and improve their communication and teamwork skills.

Group Discussion

Promote a group discussion with all students, where each group shares what they learned and their conclusions during the activities. Use the following script to introduce the discussion:

1. Ask students about the experience of working in teams and solving genetic problems in a digital environment.
2. Ask each group to present a brief summary of their findings and the approach used to solve the challenges proposed during the activities.
3. Encourage students to comment on the posts created as 'digital influencers' and the effectiveness of their scientific communication strategies.
4. Prompt a reflection on how gamification and the use of digital technology influenced engagement and understanding of the concept of linkage.

Reflections

1. What were the biggest challenges faced during the activities and how did you overcome them? 2. How did the use of digital tools help in understanding the concept of linkage? 3. How did the experience of becoming a 'digital influencer' help effectively communicate a complex scientific concept?

360° Feedback

Conduct a 360° feedback session, where each student must provide and receive feedback from their group peers. Guide students to use a constructive and respectful approach, highlighting positive aspects and suggesting areas for improvement. Use the following questions to guide the feedback:

1. What specific contributions from a colleague were most helpful to the group?
2. How could teamwork be improved for future projects?
3. What did each student learn about themselves and their own skills during the activity?

Conclusion

Duration: 10 to 15 minutes

The purpose of this stage of the lesson plan is to consolidate the acquired knowledge, relating it to the current world and its practical applications. This fun and creative review reinforces learning, showcasing the relevance of the studied content and inspiring students to see genetic science as an area full of possibilities and direct impact on society.

Summary

Let's take a quick trip through what we learned today! 🌟 The concept of linkage explained how genes close to each other on the same chromosome tend to be inherited together. We differentiated the types of linkage and solved genetic problems, all while becoming genetic detectives, digital influencers, and escaping from a virtual room full of puzzles! 🚀🧬

World Connection

In the current world, understanding linkage is crucial for advances in modern genetics and biotechnology, areas that have a direct impact on our lives, such as in the development of genetically modified foods and research on hereditary diseases. The connection with digital tools and social networks showed how science can be communicated accessibly and engagingly, reflecting the modern dynamics of information. 📱🌐

Practical Application

Understanding linkage is vital for various areas of our daily lives, such as medicine, where this knowledge helps in identifying genetic predispositions to certain diseases, and in agriculture, where it is applied in the genetic improvement of plants to increase production and resistance to pests. 🌾🔬
