Posts to PS21 - Project for the Study of the 21st Century Dear all, we are very sorry to inform you all that unfortunately we have had to take the decision to postpone Thursday's event on 'Africa in the 21st century: change, challenges and hopes' until further notice due to the growing concerns about Covid-19. Physics for the 21st Century was designed for adult learners, including high school teachers, undergraduates, and the interested public—college graduates who were non-science majors. For teachers, the course will look at advances in physics that have occurred since they took their college physics classes.

Our authentic problem-solving tasks encourage students to meet the criteria of our Standards-Based Math Rubric, based on the NCTM Process Standards. To meet the Exemplars standard, students must do more than find the correct answer. They must also communicate to justify their thinking and reasoning, use formal math language, create representations to show conceptual understanding, and make math connections.

Using our performance tasks over time in concert with our rubric expectations, students develop solutions that look like this:

21st Century Equipment

  • Grade 1 student work sample. The typed text represents teacher scribing, which helps capture a student's thinking. This student meets the Exemplars standard.
  • Grade 3 student work sample. This student uses a strategy of a labeled number line and clear math reasoning to develop justification for their solution. This student meets the Exemplars standard.
  • Grade 5 student work sample. This student justifies their solution with two different representations and clear mathematical reasoning. This student meets the Exemplars standard.
