Improving Scientific Learning and Supporting Civic Engagement for Undergraduate Non-science Majors

Description: In prior research focusing on teaching and learning science, a definitive trend toward a new approach for undergraduate non-major science courses has emerged. Instruction should be refocused from information-transfer to giving students experiences that allow them to explore and engage in their new knowledge and find ways to integrate it into their everyday lives. One technique is to focus class material on real issues of interest and relevance. Course development that allows for civic engagemen… more

Lines by Someone Else: the Pragmatics of Apprompted Poems

Description: Over the last sixty years, overtly intertextual poems with titles such as “Poem Beginning with a Line by John Ashbery” and “Poem Ending with a Line by George W. Bush” have been appearing at an increasing rate in magazines and collections. These poems wed themselves to other texts and authors in distinct ways, inviting readers to engage with poems which are, themselves, in conversation with lines from elsewhere. These poems, which I refer to as “apprompted” poems, explicitly challenge readers to… more

Synchrotron Radiation X-Ray Diffraction of Nickel-Titanium Shape Memory Alloy Wires During Mechanical Deformation

Description: Shape memory alloys (SMAs) are a new generation material which exhibits unique nonlinear deformations due to a phase transformation which allows it to return to its original shape after removal of stress or a change in temperature. It shows a shape memory effect (martensitic condition) and pseudoelasticity (austenitic condition) properties depends on various heat treatment conditions. The reason for these properties depends on phase transformation through temperature changes or applied stress. … more

Do contingency-conflicting elements drop out of equivalence classes? Re-testing Sidman's (2000) theory

Description: Sidman's (2000) theory of stimulus equivalence states that all positive elements in a reinforcement contingency enter an equivalence class. The theory also states that if an element from an equivalence class conflicts with a programmed reinforcement contingency, the conflicting element will drop out of the equivalence class. Minster et al. (2006) found evidence suggesting that a conflicting element does not drop out of an equivalence class. In an effort to explain maintained accuracy on program… more
