This resource set describes how to implement "direct measurement videos" for active learning in introductory physics and/or physical science classes. These high-resolution short videos feature tools that allow students to easily analyze physical situations: including grids, rulers, frame-counters and other screen overlays for making precise measurements. They allow analysis of quantities such as position and time without requiring additional video analysis software. This material includes best practices for using these videos, a library of videos, example class activities, and a set of model lesson with teaching tips, activity sheets, and answer keys.

This material is part of Pedagogy in Action, a library of resources for educators provided by SERC, the Science Education Resource Center. See Related Materials for a link to the portal for the main library site.

Please note that this resource requires Quicktime.

Editor's Note: These materials are highly recommended by the editors for giving students a context for conceptual understanding, and to help them visualize a physical process prior to performing calculations. Very easy to use, flexible to integrate into classroom instruction.

4. The Physical Setting

4F. Motion

9-12: 4F/H1. The change in motion (direction or speed) of an object is proportional to the applied force and inversely proportional to the mass.
9-12: 4F/H2. All motion is relative to whatever frame of reference is chosen, for there is no motionless frame from which to judge all motion.
9-12: 4F/H4. Whenever one thing exerts a force on another, an equal amount of force is exerted back on it.
9-12: 4F/H7. In most familiar situations, frictional forces complicate the description of motion, although the basic principles still apply.
9-12: 4F/H8. Any object maintains a constant speed and direction of motion unless an unbalanced outside force acts on it.

9. The Mathematical World

9B. Symbolic Relationships

9-12: 9B/H1b. Sometimes the rate of change of something depends on how much there is of something else (as the rate of change of speed is proportional to the amount of force acting).

11. Common Themes

11B. Models

6-8: 11B/M1. Models are often used to think about processes that happen too slowly, too quickly, or on too small a scale to observe directly. They are also used for processes that are too vast, too complex, or too dangerous to study.

12. Habits of Mind

12B. Computation and Estimation

9-12: 12B/H2. Find answers to real-world problems by substituting numerical values in simple algebraic formulas and check the answer by reviewing the steps of the calculation and by judging whether the answer is reasonable.
9-12: 12B/H9. Consider the possible effects of measurement errors on calculations.

Common Core State Standards for Mathematics Alignments

Standards for Mathematical Practice (K-12)

MP.4 Model with mathematics.

MP.6 Attend to precision.

High School — Algebra (9-12)

Seeing Structure in Expressions (9-12)

A-SSE.1.b Interpret complicated expressions by viewing one or more of their parts as a single entity.

Creating Equations^? (9-12)

A-CED.4 Rearrange formulas to highlight a quantity of interest, using the same reasoning as in solving equations.

Reasoning with Equations and Inequalities (9-12)

A-REI.3 Solve linear equations and inequalities in one variable, including equations with coefficients represented by letters.

High School — Functions (9-12)

Interpreting Functions (9-12)

F-IF.6 Calculate and interpret the average rate of change of a function (presented symbolically or as a table) over a specified interval. Estimate the rate of change from a graph.

Linear, Quadratic, and Exponential Models^? (9-12)

F-LE.1.b Recognize situations in which one quantity changes at a constant rate per unit interval relative to another.
F-LE.1.c Recognize situations in which a quantity grows or decays by a constant percent rate per unit interval relative to another.
F-LE.5 Interpret the parameters in a linear or exponential function in terms of a context.
