The Lawson Classroom Test of Scientific Reasoning (LCTSR) is a 24-question, multiple-choice test designed to assess students’ scientific reasoning ability. The test consists of 12 scenarios, each of which focuses on testing a specific reasoning pattern. Each scenario is followed by two questions; the first question assesses a student’s ability to apply the specific reasoning pattern being tested, whereas the second asks the student to explain the reasoning behind his or her response to the first question. This dual question approach is designed to verify that students are employing the correct reasoning patterns to reach the correct answers.
