Are you part of an AP Chemistry professional learning community?

The research says the best way to make your school better is to encourage teachers to participate in professional learning teams that unpack the standards to determine what each student should learn and how the learning will be measured, build a useful warehouse of evidence that learning is occurring, and critically review data collected to determine useful instructional strategies versus ineffective strategies.

Straight Talk from AP Chemistry Students about College Board's "AP Insight: Chemistry" Teaching Tools and Assessments

The College Board offers the opportunity to have access to guided inquiry "Building Block" performance tasks, "Building Block" digital assessments, and FRQ-style end of "Building Block" assessments directed specifically at nine "challenge areas." The "challenge areas" are organized according to the AP Chemistry six big ideas. I have used most of the resources available in AP Insight this year with my honors and AP chemistry students. Today, post-AP exam, I asked the students to provide me with feedback about the usefulness of those resources.

Do you have a favorite acid-base titration lab?

HCl and NaOH, a strong acid - strong base titration? Citric acid and NaOH, a weak, triprotic acid - strong base titration? Do your students standardize the NaOH solution as a first step?

Excellent Resource for Teaching Chemical Kinetics

Chemical kinetics is one of the five challenge areas in AP Chemistry. My students and I have been working our way through one of the teaching and learning activities called Concentration vs. Time. The graphical analysis, guided-inquiry questions, and application to past and future content are seriously challenging, and my students report higher levels of understanding than in past semesters.

Supporting Individual Lab Accountability in Large Science Classes

Lab practicals

How do teachers encourage building individual lab skills in classes of over 30 students where labs are done in groups of five or six students? My science department collaborates daily, and we have been discussing this concern for a few years now. Many trials and errors have occurred. 

NO MORE UNIT TESTS...What do you think?

My students are bright and motivated. Most work hard and prepare for class and tests. They perform extremely well on district-wide tests and my own classroom tests. However, I see real weaknesses on cumulative assessments requiring high levels of application. My students simply do not retain the content knowledge. I want to restructure my course to exclude "unit tests" and include only cumulative assessments. I'll share my early ideas here, and I would love to hear your experiences.
