    Andragogy vs. Pedagogy: Comparing Adult and Children's Learning Preferences

    Get PDF
    [iii], 58 leaves. Advisor: Thomas S. Westbrook.The Problem: Andragogy and pedagogy have been regarded as two completely separate methods of teaching for many years. After much debate, the two methods have become opposite ends of a continuum used to describe the extremes of interactions occuring between a teacher and students. The purpose of this study was to explore the extent to which there are differences and similarities in adults' and children's learning preferences. Procedures: The study included both a review of the literature comparing andragogy and pedagogy, results from a questionnaire developed by the author and interviews of adults and children as to how they learn best, their learning preferences, and what they perceive to be effective learning environments and instructors. Findings: Results of the study found that adults and children prefer to learn in the same general manner. In addition, no significant differences were found in the methods used to teach adults and children. The results indicate that individuals prefer hands-on activites combined with guided practice from the teacher, interaction with others, positive environments, and relevant materials and topics to their lives. Conclusions: The conclusions of this research are: fundamentally, children's preferences for learning are smiliar to adults, teaching methods using andragogical and pedagogical procedures are situational and should be used based on the needs of the learner, results neither support no dismiss Knowles' notion of pedagogy and andragogy serving as two ends of a teaching methods continuum. Results from the sample group indicate children's learning preferences favor andragogical approaches rather than pedagogical approaches and children are more concerned with technology and access to it that adults. Recommendations: It is recommended that others repeat the study with a larger group of individuals, including greater diversity among the adults' educational level, to further recognize similiarities and differences between adults and children and teach adults and children with those methods we would like them to use throughout their lives

    [x], 121 leaves. Advisor: Janet McMahill.The problem: The purpose of this study was to determine the computer literacy and word processing skill level of central Iowa high school seniors. Computer literacy was defined as computer terminology, troubleshooting, and appropriate use of technology, legal and ethical issues in technology, and Internet research and evaluation. Word processing was defined as the ability to create documents using word processing software and incorporate tables and graphs from other applications (TekXam Manual, 2001) Procedures: The study employed 113 central Iowa high school seniors, randomly selected from a stratified sample of districts by size, during the spring semester of their graduating year. Several questions were asked to determine if differences existed in test scores between students with various levels of access to computers at school and home, gender, and school size. Students and administrators completed demographic sheets to gain insight regarding computer usage and availability. Student demographic variables included gender, computer availability at home, and computer courses taken beyond the basic keyboarding. Administrator demographic variables included technology money available for each building and district, student: computer ratio, number of computers in the building with access to the Internet, and the comfort and skill level of teachers with various computer applications. Findings: The findings included statistically significant results on the General Computing Concepts module for those students who had access to a computer to complete schoolwork and those who did not and the Word Processing module between medium and large and non-public schools. No statistically significant differences were reported in regard to gender, having a computer at home, or taking a computer course beyond basic keyboarding. Seven of 113 students passed the general computing concepts module; while forty-one of 113 students passed the word processing module. Conclusions: The findings reject conclusions that central Iowa high school seniors have the necessary computer literacy and word processing skill to pass the TekXam assessment evaluation. Recommendations: Recommendations for future research include: expanding the study to include a larger sample; conducting a study on the type of technology and connectivity available to the various districts; conducting a study to ask employers if a passing score on the TekXam assessment evaluation would make a difference in hiring an employee and conducting a study of the comfort and skill level of teachers teaching technology skills

    This document is the Accepted Manuscript version. The final publication is available at Springer via http://dx.doi.org/10.1007/s12208-013-0112-xGreece has high rates of obesity and non-communicable diseases owing to poor dietary choices. This research provides lessons for social marketing to tackle the severe nutrition-related problems in this country by obtaining insight into the eating behaviour of young adults aged 18–23. Also, the main behavioural theories used to inform the research are critically discussed. The research was conducted in Athens. Nine focus groups with young adults from eight educational institutions were conducted and fifty-nine participants’ views towards eating habits, healthy eating and the factors that affect their food choices were explored. The study found that the participants adopted unhealthier nutritional habits after enrolment. Motivations for healthy eating were good health, appearance and psychological consequences, while barriers included lack of time, fast-food availability and taste, peer pressure, lack of knowledge and lack of family support. Participants reported lack of supportive environments when deciding on food choices. Based on the findings, recommendations about the development of the basic 4Ps of the marketing mix, as well as of a fifth P, for Policy are proposedPeer reviewe

    Are adolescents with high socioeconomic status more likely to engage in alcohol and illicit drug use in early adulthood?

    <p>Abstract</p> <p>Background</p> <p>Previous literature has shown a divergence by age in the relationship between socioeconomic status (SES) and substance use: adolescents with low SES are more likely to engage in substance use, as are adults with high SES. However, there is growing evidence that adolescents with high SES are also at high risk for substance abuse. The objective of this study is to examine this relationship longitudinally, that is, whether wealthier adolescents are more likely than those with lower SES to engage in substance use in early adulthood.</p> <p>Methods</p> <p>The study analyzed data from the National Longitudinal Survey of Adolescent Health (AddHealth), a longitudinal, nationally-representative survey of secondary school students in the United States. Logistic regression models were analyzed examining the relationship between adolescent SES (measured by parental education and income) and substance use in adulthood, controlling for substance use in adolescence and other covariates.</p> <p>Results</p> <p>Higher parental education is associated with higher rates of binge drinking, marijuana and cocaine use in early adulthood. Higher parental income is associated with higher rates of binge drinking and marijuana use. No statistically significant results are found for crystal methamphetamine or other drug use. Results are not sensitive to the inclusion of college attendance by young adulthood as a sensitivity analysis. However, when stratifying by race, results are consistent for white non-Hispanics, but no statistically significant results are found for non-whites. This may be a reflection of the smaller sample size of non-whites, but may also reflect that these trends are driven primarily by white non-Hispanics.</p> <p>Conclusions</p> <p>Previous research shows numerous problems associated with substance use in young adults, including problems in school, decreased employment, increases in convictions of driving under the influence (DUI) and accidental deaths. Much of the previous literature is focused on lower SES populations. Therefore, it is possible that teachers, parents and school administrators in wealthier schools may not perceive as great to address substance abuse treatment in their schools. This study can inform teachers, parents, school administrators and program officials of the need for addressing drug abuse prevention activities to this population of students.</p

    <p>Abstract</p> <p>Background</p> <p>Consistent with global trends, the prevalence of obesity is increasing among Norwegian adults. This study aimed to investigate individual trends in BMI (kg/m<sup>2</sup>) by age, gender, and socio-economic status over an 11-year period.</p> <p>Methods</p> <p>A cohort of 1169 adults (n = 581 men; n = 588 women) self-reported BMI during a general health interview twice administered in two regions in Norway.</p> <p>Results</p> <p>Average BMI increased significantly from 23.7 (SD = 3.4) to 25.4 (SD = 3.8), with equivalent increases for both genders. Proportion of obesity (BMI ≥ 30) increased from 4% to 11% for women and 5% to 13% for men. Of those already classified as overweight or obese in 1990, 68% had gained additional weight 10 years later, by an average increase of 2.6 BMI units. The greatest amount of weight gain occurred for the youngest adults (aged 20–29 years). Age-adjusted general linear models revealed that in 1990, women with a lower level of education had a significantly greater BMI than more educated women. In both 1990 and 2001, rural men with the highest level of household income had a greater BMI than rural men earning less income. Weight gain occurred across all education and income brackets, with no differential associations between SES strata and changes in BMI for either gender or region.</p> <p>Conclusion</p> <p>Results demonstrated significant yet gender-equivalent increases in BMI over an 11-year period within this cohort of Norwegian adults. Whereas socio-economic status exerted minimal influence on changes in BMI over time, young adulthood appeared to be a critical time period at which accelerated weight gain occurred.</p

    The impact of corporate volunteering on CSR image: a consumer perspective

    Get PDF
    Received: 29 June 2013 / Accepted: 15 January 2014Abstract Corporate volunteering (CV) is known to be an effective employee engagement initiative. However, despite the prominence of corporate social responsibility (CSR) in academia and practice, research is yet to investigate whether and how CV may influence consumer perceptions of CSR image and subsequent consumer behaviour. Data collected using an online survey in Australia show perceived familiarity with a company’s CV programme to positively impact CSR image and firm image, partially mediated by others-centred attributions. CSR image, in turn, strengthens affective and cognitive loyalty as well as word-of-mouth. Further analysis reveals the moderating effect of perceived leveraging of the corporate volunteering programme, customer status and the value individuals place on CSR. The paper concludes with theoretical and managerial implications, as well as an agenda for future research.Carolin Plewa, Jodie Conduit, Pascale G. Quester, Claire Johnso

    Economics, Psychology, and Social Dynamics of Consumer Bidding in Auctions

    With increasing numbers of consumers in auction marketplaces, we highlight some recent approaches that bring additional economic, social, and psychological factors to bear on existing economic theory to better understand and explain consumers' behavior in auctions. We also highlight specific research streams that could contribute towards enriching existing economic models of bidding behavior in emerging market mechanisms.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/47034/1/11002_2005_Article_5901.pd
