Lesson Plan | Teachy Methodology | Research: Sampling

Objectives

Duration: 10 - 15 minutes

The purpose of this stage is to prepare students for the understanding and application of the skills necessary to plan and conduct sample surveys. This includes the appropriate selection of samples, the justification for choosing between sample surveys and census surveys, as well as the calculation and interpretation of measures of central tendency. These concepts are fundamental for understanding how to efficiently collect and analyze data, reflecting practices and real-life scenarios, especially in the digital context.

Main Objectives

1. Empower students to plan a sample survey by selecting the appropriate type of sample.

2. Teach how to justify the choice between a sample survey and a census survey.

3. Enable students to calculate and highlight measures of central tendency in sample surveys.

Introduction

Duration: 10 - 15 minutes

The purpose of this stage is to introduce the topic in an engaging way, speeding up the connection of students with the content they have previously studied. By using their phones to find information and share with the class, students begin to actively engage in the topic, setting the stage for deeper discussions and activities.

Warming Up

🟡 Warm-up: Start the class by briefly explaining what a sample survey is and its importance in data collection. Mention that, instead of asking everyone in a population (census survey), a sample survey involves asking only a smaller, representative group. Ask students to use their phones to find an interesting fact about sample surveys. It can be a practical application, a curiosity, or a relevant statistic. Students should share their findings with the class.

Initial Reflections

1. 🔍 What is a sample survey?

2. 🔍 When is it more appropriate to use a sample survey instead of a census survey?

3. 🔍 What are the main types of sample selection?

4. 🔍 Why is it important for a sample to be representative of the population?

5. 🔍 What are the measures of central tendency and how are they calculated in sample data?

6. 🔍 How can the use of technology facilitate the conduct of sample surveys?

Development

Duration: 70 - 80 minutes

The purpose of this stage is to allow students to practically apply the concepts previously studied. By engaging them in contextual and current activities using digital technologies, the lesson promotes active and meaningful learning, developing analytical, communication, and cooperation skills.

Activity Suggestions

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

Activity 1 - 📊 Creating a Viral Survey on Instagram

> Duration: 60 - 70 minutes

- Objective: Empower students to plan and conduct a sample survey using digital platforms, strengthening data analysis and result communication skills.

- Description: Students will create and share a sample survey on Instagram Stories to collect data on a popular topic among teenagers, such as study habits or musical preferences. They must carefully plan the sample, ensure the questions are clear and representative, and collect the results for later analysis.

- Instructions:

• Divide students into groups of up to 5 people.

• Each group should choose a relevant and interesting topic for the survey.

• Plan the sample: discuss and decide how to select a representative sample (friends, followers, specific hashtags, etc.).

• Create clear and objective questions, limiting themselves to 3-5 questions to avoid overwhelming respondents.

• Publish the survey on Instagram Stories using the poll or questions feature.

• Collect data throughout the day and record the responses.

• Analyze the collected data, highlighting measures of central tendency (mean, median, mode).

• Prepare a brief presentation with graphs and insights to share with the class.

Activity 2 - 🎮 Gamification: Research Challenge with Online Games

> Duration: 60 - 70 minutes

- Objective: Engage students through gamification, introducing them to the process of creating, administering, and analyzing sample surveys, developing analytical and communication skills.

- Description: Students will participate in a gamified competition where they create a sample survey related to online gaming preferences and collect data for analysis. The activity will be conducted through an educational gaming platform that allows creating quizzes and interactive competitions.

- Instructions:

• Divide students into groups of up to 5 people.

• Choose an educational gaming platform that allows quiz creation (e.g., Kahoot!, Quizizz).

• Define the survey topic, such as preferred types of games, daily gaming time, etc.

• Each group must plan the sample and create a questionnaire with 5-7 questions.

• Launch the questionnaire on the chosen platform and invite other students to participate.

• Collect and record the received responses.

• Analyze the collected data, calculating measures of central tendency (mean, median, mode).

• Create a visual report with graphs and insights from the collected data.

• Present the results and discuss the insights obtained with the class.

Activity 3 - 🛒 Market Researchers: Youth Consumption Trends

> Duration: 60 - 70 minutes

- Objective: Develop skills in planning and executing sample surveys, data analysis, and identifying consumption patterns, using digital tools for data collection and presentation.

- Description: Students will become market researchers, using social media to collect data on consumption trends among young people, such as fashion items, technology, or food. They must plan the sample and create a digital questionnaire to collect data and analyze the identified trends.

- Instructions:

• Divide students into groups of up to 5 people.

• Choose a topic related to youth consumption trends, such as technology, fashion, or food.

• Plan the sample: discuss and decide how to select a representative sample (followers of a specific social network, friends, interest groups, etc.).

• Create a questionnaire with clear and objective questions about the chosen topic.

• Use an online questionnaire creation tool (e.g., Google Forms, SurveyMonkey) to design and distribute the survey.

• Collect data over a specified period and record the responses.

• Analyze the collected data, highlighting measures of central tendency (mean, median, mode) and identifying consumption patterns.

• Prepare a presentation with graphs and insights about the identified trends.

• Share and discuss the results with the class.

Feedback

Duration: 20 - 25 minutes

The purpose of this stage is to consolidate learning through the exchange of experiences and reflections, in addition to promoting the development of social skills and constructive feedback. By discussing and reflecting on the challenges and successes of the activities, students reinforce their understanding of sample surveys and enhance their analytical and collaborative capabilities.

Group Discussion

💬 Group Discussion: After completing the activities, organize a collective discussion where each group can share their experiences and conclusions. Use the following outline to introduce the discussion:

'Today, we had the opportunity to apply sample surveys in different contexts. We would like each group to share the following points: The survey topic and how the sample was selected. Main challenges encountered during the development and implementation of the survey. Results obtained and the measures of central tendency calculated. Conclusions and insights that could be drawn from the collected data.'

Reflections

1. 🤔 How did the sample selection influence the survey results? 2. 🤔 What difficulties were encountered when calculating the measures of central tendency? 3. 🤔 How did the use of digital tools facilitate or complicate the survey process?

360° Feedback

🔄 360° Feedback: Instruct students to conduct a 360° feedback session, where each group member receives feedback from other peers. Guide the class to ensure that the feedback is constructive and focused on aspects such as participation, collaboration, clarity in communication, and organization of information. Use phrases like:

'I liked how you...' 'I think you could improve on...' 'It was helpful when you...'

Ensure that the environment remains respectful and positive, emphasizing that the goal is the growth and improvement of everyone.

Conclusion

Duration: 10 - 15 minutes

🎯 Purpose: The purpose of this stage is to reinforce learning and connect the concepts of the lesson with students' reality. By making a fun recap and contextualizing practical applications, we solidify the importance of what was learned and motivate students to use these skills in their daily lives. 👩‍🏫✨
