Impact Of The Engineering Design Process On Rural Female Students’ Achievement And Self-Efficacy, Whitney Lowery Oberndorf Oct 2023

Impact Of The Engineering Design Process On Rural Female Students’ Achievement And Self-Efficacy, Whitney Lowery Oberndorf

Theses and Dissertations

Nearly one-fifth of U.S. children attend rural schools; however, these students have fewer opportunities for high-quality STEM learning. Rural students are also less likely to attend college and less likely to enroll in STEM majors than their urban and suburban peers. In conjunction with these factors, female students are also less likely to pursue STEM degrees and work in STEM fields. Broadening access and exposure to these areas, as well as improving female perceptions about STEM fields, is critical to closing the gap.

Social Network Attributes Associated With Conversations About Smoking And Cessation And Differences By Socioeconomic Status, Victoria Catherine Lambert Oct 2023

Social Network Attributes Associated With Conversations About Smoking And Cessation And Differences By Socioeconomic Status, Victoria Catherine Lambert

Theses and Dissertations

Conversations about smoking and cessation in response to cessation messages appear to encourage quit attempts, yet there is some evidence that smokers with lower income and education have these conversations less often than their counterparts with higher income and education. No research has investigated the social network characteristics that encourage smokers to have these conversations or the mechanisms for SES differences in these conversations. Because social factors play a role in SES disparities in smoking and cessation as well as other health behaviors and outcomes, social network characteristics likely explain some SES differences in conversations about smoking and cessation.

Meditations On Modern America: The Ambiguous Worldview Of Transcendental Meditation, 1967-1979, Grant William Wong Oct 2023

Meditations On Modern America: The Ambiguous Worldview Of Transcendental Meditation, 1967-1979, Grant William Wong

Theses and Dissertations

Transcendental Meditation [TM], a form of silent mantra meditation pioneered by the Indian holy man Maharishi Mahesh Yogi in 1957, took the United States by storm as over two million Americans learned its meditative technique between 1968 and 1978. At once a spiritual movement and a lifestyle, TM was a countercultural movement that went mainstream. I argue that TM was appealing because of its ambiguity and consequent malleability, as its teachings and practice came to reflect the aspirations and anxieties of its followers. By tracing their varying interpretations of the practice across periodicals, movement literature, memoirs, and contemporary scholarship, I …

How Do The Students Feel? Long-Term English Learners And Their Experience Under The Esl Label, Molly M. Staeheli Oct 2023

How Do The Students Feel? Long-Term English Learners And Their Experience Under The Esl Label, Molly M. Staeheli

Theses and Dissertations

Far too many English learners in my district enter elementary school as non-native speakers, gradually developing skills only to plateau at early intermediate levels as determined by the annual proficiency exam. As these students become long-term English learners (LTELs) in junior high, the pattern of failing and retaking the test wears on them, likely exacerbated by the district-mandated curriculum for English language development (ELD) classes. Unit topics such as money matters and U.S. national monuments at advanced levels fail to tap into students’ lived experiences. I responded to this problem of practice through mixed-methods action research, beginning with a quantitative …
