Jaber, Lama Z.; Hammer, David – Journal of the Learning Sciences, 2016
Most accounts of affect and motivation in the science education literature have discussed them as relevant to, but distinct from, disciplinary pursuits. These include Pintrich's seminal work on affective and motivational factors in learning science (P. R. Pintrich, 1999, 2003; P. R. Pintrich & E. De Groot, 1990; P. R. Pintrich, R. W. Marx,…

Hammer, David; Berland, Leema K. – Journal of the Learning Sciences, 2014
We question widely accepted practices of publishing articles that present quantified analyses of qualitative data. First, articles are often published that provide only very brief excerpts of the qualitative data themselves to illustrate the coding scheme, tacitly or explicitly treating the coding results as data. Second, articles are often…

Hammer, David; Gupta, Ayush; Redish, Edward F. – Journal of the Learning Sciences, 2011
The authors appreciate Professor Slotta's responding to their critique (Slotta, this issue). For their part, they believe that Professor Slotta has misinterpreted aspects of their position. In this commentary, the authors clarify two particular points. First, they explain their use of "static ontologies," which they maintain applies. Second, they…

Gupta, Ayush; Hammer, David; Redish, Edward F. – Journal of the Learning Sciences, 2010
In a series of well-known papers, Chi and Slotta (M. T. H. Chi, 1992, 2005; M. T. H. Chi & J. D. Slotta, 1993; M. T. H. Chi, J. D. Slotta, & N. de Leeuw, 1994; J. Slotta & M. T. H. Chi, 2006; J. D. Slotta, M. T. H. Chi, & E. Joram, 1995) have contended that a reason for students' difficulties in learning physics is that students…

Rosenberg, Seth; Hammer, David; Phelan, Jessica – Journal of the Learning Sciences, 2006
Research on personal epistemologies (Hofer & Pintrich, 2002) has mostly conceptualized them as stable beliefs or stages of development. On these views, researchers characterize individual students' epistemologies with single, coherent descriptions. Evidence of variability in student epistemologies, however, suggests the need for more complex…

Hammer, David; Elby, Andrew – Journal of the Learning Sciences, 2003
Explores connections between naive epistemology and everyday instructional practice. Reviews examples of naive epistemologies as made up of fine-grained, context-sensitive resources. Presents strategies designed to help students tap those resources for learning introductory physics. Reflects on this work as an example of interplay between two…
