Designing Videogames to Instruct and Assess Conceptual Understanding of Fractions Rebecca E. Buschang Girlie C. Delacruz, Gregory K.W.K. Chung, Terry Vendlinski California Educational Research AssociationAnnual Meeting Day 1, Breakout Session 2: 2:15 p.m. to 3:45 p.m.San Diego, CA – November 18-19, 2010
Learning Goals of Game • The size of a rational number is relative to how one whole unit is defined. Behr, Harel, Post, & Lesh, 2003; Fuson, 2003; Lamon 1999
Learning Goals of Game • The size of a rational number is relative to how one whole unit is defined. Behr, Harel, Post, & Lesh, 2003; Fuson, 2003; Lamon 1999 0
Learning Goals of Game • The size of a rational number is relative to how one whole unit is defined. Behr, Harel, Post, & Lesh, 2003; Fuson, 2003; Lamon 1999
Learning Goals of Game • Only identical units can be added to create a single numerical sum. De Corte & Verschaffel, 1987; Kilpatrick et al., 2001; Mack, 1990 + + = ? + + = ? + + = ?
The Game • Instructional game (not practice game) • Assess student understanding in game • Opportunities for individualized feedback
Types of Assessments • Pre/posttest • In game • Size of coils added • Number of coils added • Size scrolled to
Types of “items” • Selected response • Open-ended
Pre/post ItemsSelected response + = • 10 • 5 • 25 • 15
Pre/post ItemsSelected response 2/5 + 3/10 = ? • 5/15 • 5/10 • 6/50 • 6/10
The figure below shows Pre/post Items Open ended The figure below shows of a whole unit shaded. Complete the figure to show where the whole unit ends. Be sure to draw lines (“|”) to show where each piece is.
Testing the Game with Students • July (pilot test) 2009 • December 2009 • March 2010 • June 2010
Types of Errors Students Make • Use resources in order • Don’t think ahead (resources) • Don’t define unit appropriately • Count dots instead of spaces • Don’t take unit end into account
Lesson Learned • Design of game impacts inferences that can be made • Order of levels • Resources given • Diagnostics and feedback depends on inferences
