As high school teachers, we know that understanding how measurement works is crucial for lab skills and for understanding significant figures. We think measurement should be an easy topic for students to learn; especially because we know that teachers begin working with students in elementary school to teach these skills. However, I, and many other teachers, have spent countless hours teaching and reteaching a seemingly simple skill.

A couple of days ago on Twitter, the ever-lasting debate between lecture and active learning reignited due to some talks at an Educational Research Conference held in Dublin. These talks stated direct guidance (which includes lecture) was superior in terms of student learning due its reduction of students’ cognitive load. The main citation used for this argument was an article by Kirschner, Sweller, and Clark published in 2006. So, let’s dive into what this article says.

Want to heat up a department meeting? Just propose that all courses have an on-line option and watch as some colleagues have strong opinions about it- be it on one side or the other. What overlooked component can be distilled from a normal in-person course into an online that could have a significant impact? Perhaps the face-to-face “live” interaction.

The flipped-classroom approach to education is undoubtedly popular, with consistent growth in the number of related books, conference sessions, and educator network memberships. Although active-learning may not be any more beneficial in a flipped classroom compared to a traditional classroom, it is clear that a flipped class can increase the frequency of active-learning opportunities.

Once one knows about Critical Pedagogy (with respect to Critical Thinking, as was covered in the ), how is that knowledge used? Can strategies be implemented that embrace Critical Pedagogy while not sacrificing content coverage? What are some ways to build criticality in students while maintaining expected requirements for classroom rigor?

The first unit in my sequence for AP Chemistry covers stoichiometry and reactions. The new AP Chemistry Course and Exam Description has identified Learning Objectives which need to be taught and practiced to ensure students perform well on the AP Chemistry Exam. I will identify and describe activities I use to teach students some of the Learning Objectives that I tie into this unit.

As teachers, we know how important it is for students to practice what they are learning and we are ever aware of the limited class time we have to provide those opportunities. We also know that our students have a full schedule of classes, are involved in extracurricular activities, work after-school jobs and may not have a strong support system and structure at home. That leaves us with the difficult question of “what do we do about homework?”
