Performance and Interpretation
Evaluating how different artistic choices in performance (vocal, physical) change the meaning and impact of a dramatic text.
Key Questions
- How does a change in vocal inflection alter the meaning of a line?
- In what ways can lighting and sound design emphasize the internal state of a character?
- Compare the experience of reading a script versus watching a live performance.
Common Core State Standards
About This Topic
Box plots (or box-and-whisker plots) provide a visual summary of a data set's distribution based on a five-number summary: minimum, first quartile (Q1), median, third quartile (Q3), and maximum. In 9th grade, students use these plots to compare different data sets and identify variability. This topic is central to the Common Core standards for summarizing and comparing data distributions.
Students learn to use the Interquartile Range (IQR) to measure the 'spread' of the middle 50% of the data, which is a more stable measure than the full range. This topic comes alive when students can create 'human box plots' where they physically stand in a line and divide themselves into quartiles, making the abstract concept of '25% of the data' a visible reality.
Active Learning Ideas
Simulation Game: The Human Box Plot
The whole class stands in order of their birth month or height. Students are then 'divided' into four equal groups to find the median and quartiles. They use a long rope to create the 'box' and 'whiskers' around the students standing at the key positions.
Inquiry Circle: Comparing the Leagues
Groups are given the heights of players from two different sports (e.g., NBA vs. MLB). They create box plots for both on the same scale and must write a report comparing the 'typical' height and the 'consistency' (spread) of the two groups.
Think-Pair-Share: Outlier Detectives
Give students a data set with one extreme value. Pairs must use the 1.5xIQR rule to mathematically determine if that value qualifies as an outlier and discuss whether it should be included in a final report.
Watch Out for These Misconceptions
Common MisconceptionStudents often think a longer 'whisker' or a wider 'box' means there are more data points in that section.
What to Teach Instead
Use the 'Human Box Plot.' Peer discussion helps students realize that each of the four sections contains the SAME number of people; a wider section just means those people's values are more spread out.
Common MisconceptionConfusing the median (the line in the box) with the mean.
What to Teach Instead
Have students calculate both for a skewed data set. Collaborative analysis of the box plot shows that the median is a physical 'middle' of the sorted list, which may not be the same as the 'balance point' (mean).
