Logarithmic Functions as Inverses
Students will understand logarithms as the inverse of exponential functions and graph basic logarithmic functions.
Key Questions
- Explain how logarithmic functions 'undo' exponential functions.
- Compare the domain and range of an exponential function to its inverse logarithmic function.
- Construct the graph of a logarithmic function by reflecting its corresponding exponential function.

About This Topic
Media literacy and bias focus on developing the skills to identify perspective and bias in international news sources. For 11th graders, this is a critical skill for navigating a world filled with misinformation. Students analyze how different news outlets frame the same global event and learn strategies for detecting bias in their own feeds. This aligns with ACTFL standards by using interpretive communication to analyze diverse media sources.
Media literacy is a skill that is best learned through practice. By engaging in collaborative investigations and gallery walks of different news sources, students can see for themselves how bias works. This active approach helps them develop a 'critical eye' and encourages them to seek out multiple perspectives before forming an opinion. It also helps them understand how cultural bias can influence the stories that media chooses to tell, making them more informed global citizens.
Active Learning Ideas
Inquiry Circle: News Comparison
Small groups choose a recent global event and compare how it was reported by three different news outlets (one from the US, one from the target culture, and one international). They identify differences in headlines, images, and tone.
Gallery Walk: Spotting Misinformation
The teacher sets up stations with examples of real and fake news stories. Students rotate through the stations, using a checklist of 'red flags' to determine which stories are reliable and why.
Think-Pair-Share: The Power of Framing
Pairs look at two different headlines for the same story and discuss how the wording changes the reader's perception. They then share their findings with the class, creating a list of 'loaded words' to watch out for.
Watch Out for These Misconceptions
Common MisconceptionStudents often think that 'bias' means a story is a lie.
What to Teach Instead
Teachers should explain that bias is often about what is included or excluded, and the tone used, rather than just factual errors. Analyzing two factual but differently-toned stories side-by-side helps students see this nuance.
Common MisconceptionThere is a belief that some news sources are completely objective.
What to Teach Instead
Discuss how every source has a perspective, even if it's just in the choice of which stories to cover. Active discussion about the 'editorial voice' of different outlets helps students recognize that objectivity is a goal, not always a reality.
