MouseLab takes an unusual approach to the study of kinematics as it explores the relationship betwen displacement, accleration, and velocity. Users can manually sketch a graph wiht the mouse showing the time history of one of these variables, and the program will calculate the other two quantities automatically. Or, you can move an object directly on the screen and MouseLab will plot the function and its derivatives for you. This form of graph manipulation encourages students to predict an objects behavior based on newly acquired learning, and it allows for exploration of functions and scenarios without the encumbrance of algebraic calculations. MouseLab is excellent for interpreting word problems in terms of motion graphs and for constructing graphs on the basis of verbal description. It is also ideal for mathematical activities like manipulating space-time diagrams and functional graphs. The program contains several model that can be used to show diferent types of manipulation: an elevator, a car, a rocket, and a falling body. By working through the various scenarios, students will begin to clearly see the distinction between constant velocity versus constant accleration. The MouseLab format creates a valuable learning environment for students. The manual graphing guarantees direct feedback from the hand to the eye (to the brain) as the curves change dynamically. When one graph is manipulated, the others are immediately updated. When the motion is replayed, a cursor line moves, underscoring the corespondence between the motion and the curve. In addition, this program is an effective activity for team labs, and it works well in conjunction with MBL assignments. 45 pp.
