Effects Of Instructor Attractiveness On Classroom Learning, Richard Shane Westfall

UNLV Theses, Dissertations, Professional Papers, and Capstones

Although there have been multiple studies examining the effects of physical attractiveness on a variety of human interactions, one domain has been largely overlooked. The current thesis examined the effect of teacher attractiveness on a learning task. Specifically participants were exposed to a photograph that they believed was their instructor while listening to an audio lecture. Upon completion of the lecture participants then completed a forced choice recognition task covering material from the lecture. I hypothesized that participants would perform significantly better on the learning task when they perceived their instructor to be high in physical attractiveness. Neither the gender …

Implicit Theories Of Intelligence And Learning A Novel Mathematics Task, Nathan Oehme Rudig

UNLV Theses, Dissertations, Professional Papers, and Capstones

The social-cognitive model of motivation states that students adopt a theory of the nature of intelligence that guides their goals in academia and their responses to academic setbacks. Students who believe intelligence is an unchanging entity within them are more likely to adopt goals to display high ability, hide low ability, and respond helplessly to failed schoolwork. Conversely, a student who believes intelligence is a measure of effort and persistence will be motivated to gather knowledge and acquire new skills. The current study investigated the role theories of intelligence play in the field of mathematics understanding. In two experiments, participants …

The Formation Of Situation Models In Multimedia, Kris Gunawan

UNLV Theses, Dissertations, Professional Papers, and Capstones

When people read traditional text-based stories, they construct mental representations of the described state of affairs, called situation models, to connect various details of events (e.g., time, space, entity) in memory (Zwaan & Radvansky, 1998). According to the cognitive theory of multimedia learning (Mayer, 2005; 2011), stories presented as pictures and text generate independent channels of mental representations that can work hand-in-hand or separately to acquire and remember the materials presented. This dissertation consisted of two experiments that were used to further explore how the two modalities affect what is being mentally represented in memory. In Experiment 1, participants were …

Second Language Gesture And Acculturation In Study Abroad Contexts, Christie Marie Gardner

UNLV Theses, Dissertations, Professional Papers, and Capstones

Motivationis an integral part of learning; Gestures are an important aspect of human communication, and culture plays a significant role in shaping all of these human elements. This study explores the relationship betweensocial, cultural-historical activityand second language(L2) gesture acquisitionas student motivations both drive, and emanate from, the L2 learning process. Six American students participating in a study-abroad program in Chile were evaluated at three different levels of L2 proficiency (beginning, intermediate, and advanced) for L2 gesture articulations and motivational developments. During the semester-long investigation, three audio-video recorded interviews were conducted to observe L2 gestural behaviors, and two e-mail logs were …

Examining The Testing Effect Using The Dual-Process Signal Detection Model, Nicole Jessica Bies-Hernandez

UNLV Theses, Dissertations, Professional Papers, and Capstones

Taking a test can lead to enhanced long-term retention compared to not practicing the information or simply restudying, a finding known as the testing effect (Roediger, Agarwal, Kang, & Marsh, 2010). The current study examined whether the dual-process signal detection (DPSD) model (Yonelinas, 1994) offers an approach for investigating the testing effect across two experiments. Experiment 1 investigated if the DPSD model could be used to examine the testing effect, and it also examined a factor (i.e., the number of practice sessions) that influences the magnitude of the testing effect. Experiment 2 investigated whether making the final test dependent on …

Interactive Effects Of Working Memory Self-Regulatory Ability And Relevance Instructions On Text Processing, Nancy Jo Hamilton

UNLV Theses, Dissertations, Professional Papers, and Capstones

Reading is a process that requires the enactment of many cognitive processes. Each of these processes uses a certain amount of working memory resources, which are severely constrained by biology. More efficiency in the function of working memory may mediate the biological limits of same. Reading relevancy instructions may be one such method to assist readers in utilizing working memory resources more efficiently.

This study examines the relationship between perspective relevance instructions and participants' ability to regulate their working memory resources. In a 3 x 2 x 2 design the study extended the literature by utilizing a measure of fluid …

Processes Of Disposition Development In K--5 Teachers, Deborah A. Obara

UNLV Theses, Dissertations, Professional Papers, and Capstones

Educators concur that teacher competency requires more than teaching knowledge and skills; competency requires appropriate professional dispositions. The development of professional dispositions is an expected outcome of teacher education programs. Since 2002, program accreditation has been contingent on documentation that prospective teachers have met national standards for dispositions. The body of educational research on disposition assessment has been growing. Research on disposition learning and development, however, has been impeded by the prevailing conceptualization of dispositions as fixed traits resistant to change. The present study conceptualized dispositions as malleable constructs within a theoretical framework that synthesized a cognitive model of thinking …
