Activity 5.5: Systems and Scale Unit Posttest (20 min)

Students retake the pretest that they took at the beginning of the Unit to assess what they have learned about materials and combustion.

Materials You Provide

  • Pencils (1 per student)

Resources Provided

Setup

Print one copy of the 5.5 Systems and Scale Unit Posttest for each student. If you are administering the pretest on the computer, register the class on the NREL website in advance, and prepare one computer with an Internet connection per student.

Directions

1. Describe the unit posttest.

Explain the purpose of the unit posttest to students:

  • It will help you as a teacher understand how students think about what happens when ethanol burns.
  • It will help them think about what they learned and how their ideas changed over time.

Assessment

Students should be able to answer the questions correctly, so it is reasonable to grade them at this point. Use 5.5 Grading the Systems and Scale Unit Posttest to check student answers. If you administer the test online, you will receive an analysis of your students’ responses that includes (a) the responses themselves, (b) grading of true-false and multiple-choice responses, and (c) estimates of the learning progression levels of your students. If you administer the test online (http://carbontime.org/Teaching/TeacherDashboard.php) you can use the My Students’ Answers feature to interpret your students’ ideas.
