This post addresses what ungrading is and why do it.

As a chemistry teacher considering the switch to standards-based grading, you might be wondering how lab reports work in a system that is not based on points. With lab reports, you just need to decide whether you are grading chemistry content skills, scientific communication skills, or both.

High School Teacher Opportunity: Summer is the ultimate time to recharge the teaching batteries. Professional development during the summer can be a great chance to stop and reflect. It provides time that does not exist during the school year to develop new and better ideas to help students.

Flipped classrooms are a popular pedagogical technique, delivering lectures before class so that students can engage in active learning and problem-solving activities during class. Although the response from students and teachers is mostly positive, the approach is not without its challenges. This post outlines some common challenges and how teachers might work through them.

 In this lesson, students are offered a variety of alternative versions of the periodic table. Students will identify trends that are consistent from one table to the next in order to understand why the tables they are working with and Mendeleev's version are organized in the manner that they are. This lesson was designed to fit the NGSS performance expectation HS-PS 1.1 but can be used for any first year chemistry course or modified at your discretion.
