In prior studies, we examined Collective Classroom Efficacy (CCE) through the role of teacher and through the voices of students in a diverse classroom developing CCE. One participant exhibited an element of hope that added to her learning experience. Through Lara's telling case, we illustrate how she accomplished her goals through interactions…

Studies have shown an association between argumentative discourse in science class, better understanding of science concepts, and improved academic performance. However, there is lack of research on how argumentation can increase student motivation. This mixed methods concurrent nested study uses Bandura's construct of motivation and concepts of…

Existing evidence suggests that high stakes exams result in little increased learning among students. Yet, given the federal mandates for greater accountability, such as No Child Left Behind (NCLB) legislation and Race to the Top policies, and the "pervasive testing culture," the use of high-stakes tests is presently an accepted…

Modeling is a core practice in science and a central part of scientific literacy. We present theoretical and empirical motivation for a learning progression for scientific modeling that aims to make the practice accessible and meaningful for learners. We define scientific modeling as including the elements of the practice (constructing, using,…
