The Influence of Social Media in Campaigns
Analyzing how digital platforms are used for micro-targeting and mobilization.
Key Questions
- Analyze how algorithmic sorting affects the information voters receive.
- Justify whether social media companies should be responsible for fact-checking political ads.
- Explain how the 'permanent campaign' has changed the way politicians govern.
Common Core State Standards
About This Topic
Population models and sustainability use exponential functions to examine global trends and resource management. Students learn about the Malthusian growth model, which predicts that population grows exponentially while food production grows linearly, potentially leading to a crisis. This topic connects Common Core math standards to environmental science and social policy, providing a powerful cultural context for algebraic modeling.
Students explore the concept of 'carrying capacity' and how real-world factors like technology and conservation can shift the curves. This topic comes alive when students can engage in 'sustainability simulations' or collaborative investigations where they use actual global data to predict future resource needs. Structured discussions about environmental policy help students see math as a tool for making informed decisions about the future of the planet.
Active Learning Ideas
Simulation Game: The Island Resource Challenge
Groups are given an 'island' with a fixed amount of resources that grows linearly. They start with a small population that grows exponentially. They must calculate when the population will exceed the resources and propose a 'sustainability plan' to prevent a crash.
Inquiry Circle: Global Population Trends
Students use actual UN population data for different countries. They must determine which countries are growing exponentially and which have 'leveled off,' discussing the social and economic factors that might be influencing the math.
Formal Debate: The Malthusian Dilemma
Students debate whether Malthus's 18th-century prediction of a population crisis is still relevant today. They must use data on agricultural technology (linear growth) and population (exponential growth) to support their arguments.
Watch Out for These Misconceptions
Common MisconceptionStudents often assume that a population will continue to grow exponentially forever.
What to Teach Instead
Use 'The Island Resource Challenge.' Peer discussion about 'limiting factors' like food, space, and disease helps students understand that in the real world, exponential growth eventually turns into 'logistic' growth as it hits a ceiling.
Common MisconceptionThinking that 'sustainability' just means stopping growth entirely.
What to Teach Instead
Use the 'Global Population Trends' activity. Collaborative analysis shows that sustainability can also involve changing the 'rate' of growth or increasing the efficiency of resources, which can be modeled by changing the variables in their equations.
