VECTORS: graphical addition before algebraic manipulation by Mr. Kley Feitosa, candidate for MNS degree with concentration in physics
NEXT MONDAY, July 22, 2013 Time: 2:10 to 3:20pm Place: Bateman Physical Sciences Center, F wing, room 462 (next to main physics dept. office) Arizona State University, Tempe
Abstract: While vectors play a significant role in understanding basic concepts in physics, most high school and college students demonstrate only rudimentary working knowledge of vectors even after taking a yearlong physics course. In developing the force
model, careful consideration to the vector concept and its operations is necessary, yet studies have shown that most instructors and textbooks hastily introduce students to abstract orthogonal decomposition of vectors when solving force problems. The purpose of this study was to evaluate how students¹ understanding of vectors and forces were impacted by introducing them to graphical addition of vectors before algebraic manipulation of vector components. The research did not find any substantial
positive correlation between graphical methods of vector addition and improved understanding of forces and vectors. However most students, particularly students who struggle with math, benefited from the geometrical approach and consequently improved their
ability to solve dynamics questions. Likewise, students who have learned how to add vectors graphically increased their problem-solving skill and added another useful ³tool² to their repertoire.
LOCATION OF CLASSROOM 462 IN THE F-WING: The Bateman Physical Sciences Center is on University Drive, west of Rural Road and east of College Avenue. It's just east of the pedestrian bridge, on the south side of the street, just east of the Student Health Center. The F wing is at the southeast.
Take the elevator to the 4th floor.
If you're driving on Loop 202: Get off at Rural Road (Scottsdale Road). Turn south.
