Diversity in the Classroom: Equity & Access
• Rigorous Courses can open the door to Academic Success
• AP Potential: Free, web-based tool to help schools identify qualified students for AP courses.
“One of the best standard predictors of academic success at Harvard
University is performance on Advanced Placement Examinations.”
William Fitzsimmons, Dean of Admissions & Financial Aid, Harvard University
Expand AP Access and Opportunities
Expanding access to more schools is needed, but if every school with an existing AP program focused on finding its own “missing students,” we could
almost entirely eliminate participation gaps.

Expectations Series, June 2013
AP Biology Exam• Exam organization
• 2016 Exam Results
• Student Performance Question & Answer - “Chief Reader Report”
“What can you do (science practices) to infer about what you know about Biology”
…Chief Reader on Key to New Exam (2013)
AP Exam Organization• Section 1:
63 Multiple Choice + 6 Grid-In Questions 90 minutes 50 % of exam weight
• Section 2: 8 Free Response Questions
2 long free response questions (one is lab based) 6 short free response questions
10 minutes required reading time + 80 minutes response time 50% of exam weight *Practice Exam available for AP Teachers
Sample Multiple Choice QuestionTwo flasks with identical medium containing nutrients and glucose are inoculated with yeast cells that are capable of both anaerobic and aerobic respiration. Culture 1 is then sealed to prevent fresh air from reaching the culture; culture 2 is loosely capped to permit air to reach the culture. Both flasks are periodically shaken.
Which of the following predicts which culture will contain more yeast cells after one week, and most accurately justifies that prediction?
A. Culture 1, because fresh air is toxic to yeast cells and will inhibit their growth B. Culture 1, because fermentation is a more efficient metabolic process than
cellular respiration C. Culture 2, because fresh air provides essential nitrogen nutrients to the culture D. Culture 2, because oxidative cellular respiration is a more efficient metabolic
process than fermentation
Sample Grid-in QuestionsThe data below demonstrates the frequency of tasters and non-tasters in an isolated population at Hardy-Weinberg equilibrium. The allele for non-tasters is recessive
How many of the tasters in the population are heterozygous for tasting?
Tasters Non-
Tasters
8235 4328
Sample Single Part Question The role of tRNA in the process of
translation was investigated by the addition of tRNA with attached radioactive leucine to an in vitro translation system that included mRNA and ribosomes. The results are shown by the graph.
In a short paragraph, describe how this figure justifies the claim that the role of tRNA is to carry amino acids that are then transferred from the tRNA to growing polypeptide chains

FRQ Review #1, 2, 3, 4, & 5
Math in Biology• Truth, Lies, and Statistics: An Intro to
the Quantitative Skills Guide - Handout
• Variability, Standard Deviation, etc….Handout
• Data Analysis Practice - Pasco Handout
• An Introduction to Statistics - Little Handout
• Evolution in Action: Statistical Analysis (HHMI)
• Chi-square and M & M’s
Quantitative Skills• AP Biology Quantitative Skills Manual
• Incorporate into curriculum: • Introduce skills early • Include in every lab activity • Warm Up Scenarios • Unit Exams include Grid In Response
Questions • Bozeman Videos • Practice - “Trial & Error” • Key is that it is a “Skill”. Must teach like a
skill • Gradual Release Model: Model the Skill,
Practice Together, Practice Alone • Start second semester with reteaching of
the skills
HHMI - Mathematics & Statistics in Biology
• Application in Biology - Example 2 - Page 15
• Great Activity for the first weeks of school
• Use to Introduce: • Standard Deviation
• Standard Error of the Mean
• 95% Confidence Interval
M & M Statistics - A Chi Square Analysis
• Chi-Square
• Probability
• Null Hypothesis
• Degrees of Freedom
