Predictors Of Anticipated Parenting Efficacy In Younger Adults, Danielle K. Tomczewski
Predictors Of Anticipated Parenting Efficacy In Younger Adults, Danielle K. Tomczewski
Graduate Theses, Dissertations, and Problem Reports (ETD)
Prior research has indicated that anticipated parenting efficacy, the degree to which individuals perceive that they will be an effective parent, predicts their later parenting competency (Coleman et al., 2002; Teti & Gelfand, 1991). Although additional correlates of parenting efficacy have been identified, such as knowledge of childhood development (Conrad, Gross, Fogg, & Ruchala, 1992) and prior contact with children (Coleman & Karraker, 2000; Williams et al., 1987), little research has examined the predictors of anticipated parenting efficacy. The current study examined anticipated parenting efficacy in a sample of 481 younger adults. Participants completed self-administered on-line surveys related to their …

How Do College/University Teacher Misbehaviors Influence Student Cognitive Learning, Academic Self-Efficacy, Motivation, And Curiosity?, Sara R. Banfield
Graduate Theses, Dissertations, and Problem Reports (ETD)
The purpose of this research was to examine the relationship between teacher misbehaviors and a variety of outcome variables, including cognitive learning, motivation, curiosity, and academic self-efficacy. Research has yet to directly address how teacher misbehaviors affect cognitive learning. It is important to assess actual learning as opposed to perceived learning to truly measure how a students' learning is influenced by the negative behaviors. Motivation, curiosity, and academic self-efficacy have been found to have a positive relationship with learning. When misbehaviors were present cognitive learning and motivation were not found to be significantly influenced by misbehaviors. Academic self-efficacy and curiosity …
Measuring And Changing Negative Stuttering Stereotypes In Adolescents, Timothy W. Flynn
Measuring And Changing Negative Stuttering Stereotypes In Adolescents, Timothy W. Flynn
Graduate Theses, Dissertations, and Problem Reports (ETD)
Stuttering is known to carry stereotypes, e.g., that people who stutter are nervous, anxious, and shy. Research has shown that negative stereotypes about people who stutter exist within the general population. Moreover, negative stereotypes exist among teachers, students, speech-language pathologists, and even the parents of people who stutter. While public opinion of stuttering does not vary dramatically between populations, the ways in which we might change it does. Research has shown that educational videos, books, and classes about stuttering do not appear to significantly alter public opinion positively.;This study compared the effectiveness of two forms of advocacy, a live presentation …

An Experimental Analysis Of Preference For Rate Building, Andrew R. Lightner
An Experimental Analysis Of Preference For Rate Building, Andrew R. Lightner
Graduate Theses, Dissertations, and Problem Reports (ETD)
Educational research suggests that rate-building procedures produce superior academic performance and are preferred by participants when compared to traditional methods. However, these studies have not controlled for critical variables, such as practice, that might influence preference and performance. The current study compared two conditions using behavioral performance and preference measures; one condition had a correct response rate criterion and the other had an overall correct response criterion. Reinforcement and feedback were held constant across conditions. Most participants preferred the condition that did not have a rate criterion. Performance outcomes produced by the two conditions were not substantially different. This implies …
