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?

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.
Teachers are accustomed to implementing new learning standards developed by state or national leaders. My state, Georgia, chose not to adopt the newest national standards. State leaders wrote the “Georgia Standards of Excellence” instead. Full implementation of the GSE begins in the 2017-2018 school year.
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.
College Board offers an excellent online resource for teachers and students. It's not free, but my school district pays the bill. AP Insight provides curriculum outlines, teaching ideas and resources, student handouts, and digitally-graded assessments.
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.
On June 20, 2016 at 6:34 P.M. E.S.T., our sun achieves the most northern point in its journey and stops. The summer solstice marks the moment when the sun stands still; a Latin derivative from the words sol, meaning ”sun”, and sistere, meaning “to come to a stop.” Imagine the wonder and curiosity associated with such a phenomenon in the ancient world!
Our new administrative team now strongly encourages all core content teachers to provide a summer assignment to prepare students for the first day of school. Outside of the summer reading for literature classes, we’ve never done this. I see the potential for class time-savings and improvement of student understanding. Will the students see the possibilities? What should I assign? Is it realistic to expect next year to begin differently?
