Teaching Strategies
The following are the strategies I employ to create a
relatively low stress
community of learners in my AP chemistry class:
- I give six problem sets covering chapters 1-3 as
summer assignment to be turned in to me twice during the summer. In
addition, students outline the three chapters. During the first week of
school, I go over the high points of these chapters such as writing formulas
and nomenclature, dimentional analysis, problem solving strategies, based on
my analysis of their summer work.
- On the first day of school, I give my students a
handout titled “Lessons of the Geese”. This is to emphasize the advantage
of a community in which members work together and help one another to
succeed. Like the geese, those who understand concepts must pull those who
are slow to understand along so that everybody passes the AP exam with a
minimum score of 3. I encourage them to form study groups and this has
worked extremely well
- I limit my lectures to briefly explaining the
essential points of the concepts. I spend a lot of time on group
discussions, solving example problems on the board, usually past AP
questions. I teach them how to analyze a question and break it down to
solvable steps. Students take turns to solve problems with prompt and hints
from me.
- During second semester the first 5 minutes of class is
spent on the “Net Ionic Equation of the Day” taken from past AP questions.
We analyze, classify the reaction, review the applicable solubility rules,
the correct molecular and/or ionic formulas as well as balancing the
equation.
- For each chapter, I assign 20-25 problems on “Webassign”,
a web based program with multiple submissions for questions. The questions
are from the required textbook. Students outline each chapter to include
essential points and equations.
- I give short quizzes(10-15 minutes), project the
solutions and have students grade themselves. This allows them to see model
answers, identify their weaknesses and build confidence. Honesty is
emphasized in this activity.
- I assign topics that relate chemistry to every day
life (Ex. Alternative energy sources, greenhouse gases and global warming,
indoor air pollution, Benefits and Risks of Nuclear Energy) to students for
them to research, make Power Point slides and make presentations to the
class at different times during the year.
- I give major tests on two chapters at a time to
include multiple choice and free response sections. Most of the questions
are past AP questions.
- I do demonstrations and also use animations to clarify
some points and make the atmosphere lively.
- Students turn in ten abstracts of current articles
related to chemistry during the fall semester. Periodically, I pick the
articles that have strong relevance to the topics we cover for class
discussion.
- Three weeks are spent on structured review for the AP
exam.
- All my AP students must take the ACS Local Chemistry
Olympiad exam in March. This enables students to identify their weaknesses.
