Book Chapter
The purpose of this assessment probe is to elicit students' ideas about pairs of forces that fit Newton's third law. The probe is specifically designed to reveal whether students can identify third law force pairs as involving different objects. The ...
Book Chapter
The purpose of this assessment probe is to identify how students interpret a motion diagram and whether they have an operational understanding of the concept of speed. The probe is designed to show whether students can interpret the intervals (i.e., ...
Book Chapter
The purpose of this assessment probe is to elicit students' ideas about circular motion and forces. The probe is designed to reveal whether students understand that turning requires a force toward the center of the curve....
Book Chapter
The purpose of this assessment probe is to elicit students' ideas about weight and mass when a property of an object changes. The probe is especially designed to determine whether students recognize that although weight and mass are different, both t...
Book Chapter
What Will Happen to the Weight?
The purpose of this assessment probe is to elicit students' ideas about weight. The probe is designed to determine whether students recognize that the gravitational force on an object, and thus its weight, is the same whether an object is floating in...
Book Chapter
The purpose of this assessment probe is to elicit students' ideas about gravity. The probe is designed to reveal whether students recognize that gravitational force is universal and that it works on every object in the universe regardless of what the...
Book Chapter
The purpose of this assessment probe is to elicit students' ideas about how objects with different masses (or weights) behave in free fall where air resistance is negligible. The probe shows whether students can relate their beliefs about how objects...
Book Chapter
The purpose of this assessment probe is to elicit students' ideas about gravity. The probe is designed to reveal whether students recognize that objects closer to the center of Earth's mass experience the greatest gravitational force. The probe also ...
Book Chapter
The purpose of this assessment probe is to elicit students' ideas about Earth's gravity. The probe is designed as a thought experiment to determine whether students recognize that Earth's gravity pulls falling objects toward its center....
Book Chapter
The purpose of this assessment probe is to elicit students' ideas about pulleys. The probe is specifically designed to find out whether students think the size of a pulley has an effect on how much easier it is to lift an object (mechanical advantage...
Book Chapter
The purpose of the assessment probe is to determine whether students can translate a motion diagram into a graph—a position versus time graph—to represent the motion of a moving object....
Book Chapter
The purpose of this assessment probe is to elicit students' ideas related to pulleys and mechanical advantage. The probe is specifically designed to investigate student intuition about tension, which is another name for the force exerted by ropes or ...
Book Chapter
The purpose of this assessment probe is to elicit students' ideas about center of mass. The probe is specifically designed to see if students recognize that when an object is balanced on a fulcrum, it does not mean that the parts on either side of th...
Book Chapter
The purpose of this assessment probe is to elicit students' ideas about balancing. The probe is specifically designed to see if students recognize that objects with different weights (or masses) can be balanced using a simple mathematical rule....
Book Chapter
The purpose of this assessment probe is to elicit students' ideas about levers and fulcrums. The probe is specifically designed to determine whether students can differentiate between the concept of force and the concept of energy in the context of l...
Book Chapter
The purpose of this assessment probe is to elicit students' ideas about gears. The probe is specifically designed to determine whether students use the concept of gear ratios....
Book Chapter
One of the primary difficulties that students experience in determining the speed of a moving object is differentiating between quantities and changes in quantities. The purpose of this probe is to examine students' use of ratios that express displac...
Book Chapter
The purpose of this assessment probe is to determine whether students recognize that there is a variety of measurement units, described as ratios, that can be used to express average speed, even though some units may not be practical for the situatio...
Book Chapter
The purpose of this assessment probe is to elicit students' ideas about gravity. The probe is designed to reveal whether students recognize that gravitational force is a pull by the Earth, toward the Earth, regardless of whether an object is falling ...
Book Chapter
The purpose of this assessment probe is to elicit students' ideas about pendulums. The probe is specifically designed to find out what variables students think affect the time it takes a pendulum to swing back and forth. In addition, if students have...
Book Chapter
The purpose of this assessment probe is to see whether students recognize that units of distance traveled must be measured with a measurement device from the starting point to the ending point. The probe reveals whether students take into account the...
Book Chapter
The purpose of this probe is to examine how students interpret a graphical representation of motion. The probe is designed to reveal whether students interpret a motion graph pictorially or mathematically....
Book Chapter
The purpose of this assessment probe is to elicit students' ideas about comparing motions. The probe is designed to see if students differentiate between the concept of position and the concept of speed. The probe will also help to see if students un...

Case Study: A Question of Responsibility—Whose Asbestos Caused Her Lung Disease?
This actual lawsuit, tried in 2006 in Madison County, Illinois, provided the inspiration for a case used in a Physical Geology course. The case is used to teach mineralogy as well as touch on the complexities of melding science and policy. ...
