Effects of Motivational Beliefs and Instructional Practice on Students' Intention to Pursue Majors and Careers in Engineering

Tendhar, Chosang 24 April 2015 (has links)
This dissertation examined the differences in group mean scores of traditional and pilot groups on the students' motivational beliefs and their intention to pursue majors and careers in engineering. The difference between the two groups was in terms of instruction techniques used. The instructional techniques used for the traditional group was that of traditional engineering design (TED), while the technique used for the pilot group had more features of an active learning approach. Further, it tested the tenability of the domain identification model. The domain identification model was used to understand students' decision-making processes in committing to engineering majors and engineering careers. The data for this study was collected via online survey from first-year engineering students enrolled in an introductory engineering course at a research-intensive university located in southeastern US. The sample sizes of the traditional group and pilot group at the beginning of the semester were 875 and 188, respectively. The sample sizes of the traditional group and pilot group at the end of the semester were 812 and 242, respectively. The mean differences between the two groups were computed using t-tests via SPSS version 22.0. The causality hypothesized among variables in the domain identification model were tested using structural equation modeling (SEM) techniques. The measurement and structural models were estimated using LISREL version 9.1. This study followed the two-step SEM approach that Anderson and Gerbing (1988) suggested. A measurement model with an acceptable fit to the data was obtained followed by an estimation and evaluation of structural models. All the independent sample t-tests were not statistically significant indicating that the mean scores of students in the two groups did not differ significantly on any of the motivational and intention variables. The hypothesized measurement and structural models provided a good fit to the data. A few post-hoc revisions were made to the models. This study brought empirical evidence that the domain identification model can be used to understand students' major-and career-decision making processes. Engineering identification was a better predictor of major intention and career intention compared to engineering program utility, engineering program belonging, and engineering program expectancy. / Ph.

Learning Analytics: Understanding First-Year Engineering Students through Connected Student-Centered Data

Brozina, Stephen Courtland 03 December 2015 (has links)
This dissertation illuminates patterns across disparate university data sets to identify the insights that may be gained through the analysis of large amounts of disconnected student data on first-year engineering (FYE) students and to understand how FYE instructors use data to inform their teaching practices. Grounded by the Academic Plan Model, which highlights student characteristics as an important consideration in curriculum development, the study brings together seemingly distinct pieces of information related to students' learning, engagement with class resources, and motivation so that faculty may better understand the characteristics and activities of students enrolled in their classes. In the dissertation's first manuscript, I analyzed learning management system (LMS) timestamp log-files from 876 students enrolled in the FYE course during Fall 2013. Following a series of quantitative analyses, I discovered that students who use the LMS more frequently are more likely to have higher grades within the course. This finding suggests that LMS usage might be a way to understand how students interact with course materials outside of traditional class time. Additionally, I found differential relationships between LMS usage and course performance across different instructors as well as a relationship between timing of LMS use and students' course performance. For the second manuscript, I connected three distinct data sets: FYE student's LMS data, student record data, and FYE program survey data that captured students' motivation and identity as engineers at two time points. Structural equation modeling results indicate that SAT Math was the largest predictor of success in the FYE course, and that students' beginning of semester engineering expectancy was the only significant survey construct to predict final course grade. Finally, for the third manuscript I conducted interviews with eight FYE instructors on how they use student data to inform their teaching practices. Ten themes emerged which describe the limited explicit use of formal data, but many instructors use data on an informal basis to understand their students. Findings also point to specific, existing data that the university already collects that could be provided to instructors on an aggregate, class-level basis to help them better understand their students. / Ph.

The mediating effects of family resilience processes in the context of paternal incarceration: A structural-equation analysis of the Family Inequality Framework among Danish families with school-aged youth

Morgan, Amy Alida Audrey 10 March 2020 (has links)
Approximately 63% of all incarcerated individuals in the U.S. identify as a parent (Glaze and Maruschak, 2010), with as many as 7% of children experiencing parental incarceration at some point in their lives (Murphey and Cooper, 2015). Historically, much of the parental incarceration literature has relied on between-groups comparison research, highlighting risks and determinants of pathology for youth with an incarcerated parent. However, significantly less research has attempted to understand resilience processes in the context of parental incarceration from a within-group resilience perspective. The overall goal of this dissertation research was to empirically test the theoretical Family Inequality Framework (Arditti, 2018) and better understand how family resilience processes influence the relationship between material hardship and child outcomes within the context of parental incarceration. Structural equation modeling was used to perform a mediational cross-sectional analysis. Results of these analyses suggest that parental mental health processes play an important role in mitigating adverse outcomes for families by mediating the effects of material hardship on youth academic adjustment in the context of parental incarceration. Theoretical, clinical, and policy implications, as well as future research directions are discussed. / Doctor of Philosophy / Approximately 63% of all incarcerated individuals in the U.S. identify as a parent (Glaze and Maruschak, 2010), with as many as 7% of children experiencing parental incarceration at some point in their lives (Murphey and Cooper, 2015). Historically, much of the existing research on parental incarceration is problem focused, painting these families in a negative light. In contrast, there is very little research highlighting the unique strengths and resiliences of families impacted by parental incarceration. The goal of this dissertation research was to better understand how family resilience processes, such as social support, parenting practices, and parental mental health, might reduce the negative impact of parental incarceration. Results suggest that parental mental health processes play an important role for overall family wellness during parental incarceration. In particular, the more a parent says they are doing well from a mental health perspective the better their kids appear to be doing in school. In this way, parental mental health wellness appears to provide a buffering effect against the common risks parental incarceration can introduce into a family. Theoretical, clinical, and policy implications, as well as future research directions are discussed.

The relationship among middle school students' motivation perceptions of science class, science identification and career goals

Sun, Wei 04 June 2018 (has links)
This dissertation examined the extent to which pre-high school students' motivation-related perceptions of their science class affected their science identification, which sequentially affected their future science-related career goals. The MUSIC® Model of Motivation (Jones, 2009, 2018) includes five components (i.e., eMpowerment, Usefulness, Success, Interest, and Caring) and is designed to help teachers design instruction to promote students' motivation. Domain identification (Osborne and Jones, 2011) is a concept closely related to students' motivation and academic outcomes. In this study, data was collected from 311 pre-high school students and Structural Equation Modeling (SEM) analysis was conducted to test the structure pattern among the MUSIC model components, science identification, and science-related career goals. Results indicate that with three of the MUSIC model components (i.e., usefulness, success, and interest) significantly related to students' science identification, students' science identification was highly correlated to their science career goals. Moreover, this study demonstrated the structure patterns among the MUSIC model components and science identification varied by gender by conducting multi-group SEM analyses for a separate female sample (N = 161) and male sample (N = 150). Consistently, students' science identification was a strong predictor of their science career goals in both female and male groups. These findings are important for STEM educators because they indicate that it may be possible for teachers to impact students' science identification and career goals by focusing on students' perceptions of the MUSIC model components in science class. Moreover, these results contribute to the study of the large gender gap in STEM careers. Teachers can focus on specific teaching strategies and help female students develop their science identification in ways that lead to their long-term science-related career goals. / Ph. D.

Causality analysis of media influence on environmental attitude, intention and behaviors leading to green purchasing

Trivedi, Rohit, Patel, J.D., Acharya, N. 06 June 2018 (has links)
Yes / This research provides a comprehensive delineation of the process that leads to the formation of green behavior by including the role played by media and attitude towards environment-friendly packaging, along with ecological concern and perceived consumer effectiveness. The study offers a parsimonious framework that measures the major antecedents of environmental attitude divided into inward and outward orientation. Moreover, it also measures the effects of these environmental attitudes and attitude towards green packaging on green purchase intention. A total of 308 usable questionnaires were obtained from Indian consumers and data analysis was conducted using confirmatory factor analysis and structural equation modeling. The results show that inward environmental attitude and attitude towards green packaging play a pivotal role in shaping green purchase intention. Surprisingly, outward environmental attitude was found to be non-significant. Findings offer implications for marketing managers and public policy makers, as well as reveal fruitful avenues for further research.

The Influence of Institutional and Conductive Aspects on Entrepreneurial Innovation: Evidence from GEM Data

Arabiyat, T, Mdanat, M, Haffar, Mohamed, Ghoneim, A, Arabiyat, O January 2019 (has links)
Yes / Purpose – The main purpose of this study is to improve the understanding of how different aspects of the national institutional environment may influence the level of innovative entrepreneurial activity across countries. Several institutional and conductive factors affecting a country’s capacity to support innovative entrepreneurship is explored. Design/methodology/approach – Institutional theory is used to examine the national regulatory, normative, cognitive, and conducive aspects that measure a country's ability to support innovative entrepreneurship. A cross-national institutional profile is constructed to validate an entrepreneurial innovation model. The impact of country-level national institutions on innovative entrepreneurial activity as measured by Global Entrepreneurship Monitor (GEM) data is assessed through structural equation modeling (SEM). Findings – Knowledge about the influence of specific institutional aspects on innovative entrepreneurship, and hence of institutional structures within and across countries, is enhanced. For new innovative enterprises, conductive and regulatory aspects seem to matter most. All conductive factors have a significant and positive impact on entrepreneurial activity rates. Research limitations/implications – Results could support policy makers and practitioners in evaluating government policies’ effect on innovative entrepreneurship. Interventions should target both individual attributes and context. Future research could include longitudinal designs to measure the direction of causality. Practical implications – Aspects such as regulatory institutions, and conductive factors such as ICT use and technology adoption, are important for innovation entrepreneurship development. / The full text will be made available when the article is officially published.

Blockchain technology for supply chains operating in emerging markets: an empirical examination of technology organization-environment (TOE) framework

Chittipaka, V., Kumar, S., Sivarajah, Uthayasankar, Bowden, J.L., Baral, M.M. 02 August 2022 (has links)
Yes / Organizations adopt blockchain technologies to provide solutions that deliver transparency, traceability, trust, and security to their stakeholders. In a novel contribution to the literature, this study adopts the technology-organization-environment (TOE) framework to examine the technological, organizational, and environmental dimensions for adopting blockchain technology in supply chains. This represents a departure from prior studies which have adopted the technology acceptance model (TAM), technology readiness index (TRI), theory of planned behavior (TPB), united theory of acceptance and use of technology (UTAUT) models. Data was collected through a survey of 525 supply chain management professionals in India. The research model was tested using structural equation modeling. The results show that all the eleven TOE constructs, including relative advantage, trust, compatibility, security, firm’s IT resources, higher authority support, firm size, monetary resources, rivalry pressure, business partner pressure, and regulatory pressure, had a significant influence on the decision of blockchain technology adoption in Indian supply chains. The findings of this study reveal that the role of blockchain technology adoption in supply chains may significantly improve firm performance improving transparency, trust and security for stakeholders within the supply chain. Further, this research framework contributes to the theoretical advancement of the existing body of knowledge in blockchain technology adoption studies.

Amirkiaee, Seyede Yasaman 05 1900 (has links)
This manuscript includes an investigation of decision making in alternative modes of transportation in order to understand consumers' decision in different contexts. In essay 1 of this study, the motives for participation in situated ridesharing is investigated. The study proposes a theoretical model that includes economic benefits, time benefits, transportation anxiety, trust, and reciprocity either as direct antecedents of ridesharing participation intention, or mediated through attitude towards ridesharing. Essay 2 of this study, focuses on self-driving vehicles as one of the recent innovations in transportation industry. Using a survey approach, the study develops a conceptual model of consumers' anticipated motives. Both essays use partial least square- structural equation modeling for assessing the proposed theoretical models.

Students' attitude to educational loan repayments : a structural modelling approach

Ismail, Sharinar January 2011 (has links)
Educational loan defaulting is a problem increasing on a worldwide scale. In Malaysia, the default rate is almost 50% in the case of loans advanced to students in higher education. With this in mind, for the first time, this study analyses this chronic problem in-depth with consideration to primary data collected from a cross-section of students currently studying in public universities in Malaysia. With help from the Theory of Planned Behaviour, the empirical analysis establishes that loan defaults are influenced by a complex interaction of personal-, social- and psychology-related variables: students’ attitude, intention to repay loan, parental influence, perceptions that loan repayment will affect quality of life after graduation, perceptions towards loan agreement, and an awareness of loan repayment issues created by the media. This study succeeds in disentangling the precise impact of such variables in regard to loan defaults. The findings are of great relevance to government-funding agencies, which can better plan the loan advancement and recovery process once they understand the true reasons behind defaults. The novel method utilised for the first time with the objective to study the default issue should also be useful to academic researchers seeking to conduct similar studies in the context of other countries. This study should also assist policy makers in planning long-term strategies in terms of assessing, designing and evaluating new loan schemes. Developing countries, such as Malaysia, face competing demands on their limited financial resources. An increase in the recovery rate will bring in funds that can be lent to additional students or used for strengthening educational infrastructure. These measures add useful value to the social and economic set-up of the country.

"Sport as a resource caravan" : examining the role and efficacy of sport as a resource provider for adults in transition

Walsh, David William 19 September 2014 (has links)
Sport development is an emerging discipline in sport management due in part to the popular, normative associations between sport and its beneficial outcomes. However, concerns on how sport is used and designed as well as the miscomprehension of the word development cloud sport's utilitarian prospectus. Although research has started to address these concerns in youth and adolescent forums, research on adults using sport for developmental purposes is widely ignored. With life expectancy growing, the pressure to sustain living quality in late adulthood has become almost unmanageable. Maintaining quality of life in late adulthood is difficult. Drawing from human development and aging literature, quality of life is still possible in light of the challenges presented by multiple developmental forces. Developmental trajectories are the products of net gains and losses over the life course and are influenced by transitional events and the ability in people to adapt to them. In addition, development is both cumulative and innovative, which affirms that people in later stages of life can still develop. In order to do this, gerontological and psychological research argue that resources are key in the achievement of positive outcomes. However, research understanding mechanisms that affect resources that produce positive gains is still in its infancy. Hence, I constructed a dissertation with two studies using a multi-method approach to ascertain the role and efficacy of sport participation on the transitional process that undergirds the developmental trajectory. The impetus for this approach was to examine the utility of sport as a developmental force adults could consider in improving their overall quality of life. Study 1 used a life-history, qualitative method that reveals sports' role as an influential resource provider during life event transitions across a person's life. Data show that sport was believed to aid in the adaptation process that provided distinct benefits that other activities or support structures could not match or replicate easily. Study 2 used structural equation modeling to specify the magnitude of sport's role on resources during a specific transitional event that most adults will experience: retirement from the workforce. Quantitative evidence from this study yields support that sport participation can positively impact resources and retirement well-being directly. Both studies supply substantiation for the argument that sport participation can act as a positive developmental force for adults by assisting with the recruitment of resources and acting as a resource provider which affords adaptation assistance in transitions. The combined results demonstrate how sport may be viewed as a developmental tool which has practical implications for sport development and managers wishing to design sport for this purpose. In addition, the common assumption that sport development programming should be geared exclusively toward youth and adolescents is dismissed. This dissertation provides theoretical and empirical justification for creating positive adult developmental programming in sport. / text
