Globalization affects many aspects of American society, including higher education. Many institutions of higher education realize the need to help students become global citizens and thus require an international perspectives course as part of their undergraduate curriculum. The goal of this research was to evaluate the Horticulture Travel Course (Hort 496), which includes an international travel component, to determine whether it meets the university and College of Agriculture's expected learning outcomes and competencies in international and multicultural awareness. A 23-question survey instrument consisting of open- and close-ended questions was mailed to 116 former Hort 496 participants. Forty-three percent of ...

It Only Takes Once: Influence Of Sexual Risk Status, Social Comparison, And A Public Service Announcement On Absent-Exempt Cognitions, Michelle Leigh Stock Jan 2007

It Only Takes Once: Influence Of Sexual Risk Status, Social Comparison, And A Public Service Announcement On Absent-Exempt Cognitions, Michelle Leigh Stock

Retrospective Theses and Dissertations

The current study is an extension of an ongoing program of research, based on the Prototype/Willingness Model (Gibbons, Gerrard, & Lane, 2003), which suggests that peer-based prevention messages may reinforce absent-exempt thinking, rather than reduce it (Stock et al., 2007). Absent-exempt thinking is the belief that if one has not experienced negative health consequences, in spite of having engaged in risky behavior, then one is unlikely to do so in the future (Weinstein, 1984, 1987). The present study provided an experimental demonstration of how social comparison prompted by a health message influences health cognitions (endorsement of absent-exempt thinking, willingness to engage in risky sex, prevalence estimates of risky sex on campus, favorability of risky sex prototypes, and perceptions of vulnerability to STDs). College students (N = 222) at either high or low risk of contracting STDs were randomly assigned to: (a) listen to a social comparison target who was a STD-positive student, despite engaging in low-risk sexual behavior (i.e., sex with one partner only a few times without a condom); (b) to hear a Public Service Announcement (PSA) that emphasized "it only takes one time" or (c) to hear no information about STDs. Participants then completed a questionnaire that assessed their risk-promoting cognitions and were then given the opportunity to read information on an STD.;It was predicted that high-risk participants in the social comparison group would report the highest levels of risk cognitions, whereas high-risk participants in the control condition would report lower levels of the risk promoting cognitions ...


The Effectiveness Of Using Wimba Voice Tools In Foreign Language Instruction, Lingli Yao Jan 2007

The Effectiveness Of Using Wimba Voice Tools In Foreign Language Instruction, Lingli Yao

Retrospective Theses and Dissertations

In the past two decades, text-based synchronous and asynchronous communication tools have been used as teaching tools in foreign language classes and have been researched intensively for their pedagogical implications. Although their benefits have been identified in foreign language instruction, these benefits are mainly limited in affecting learners' reading and writing skills due to the tools' text-based nature. Since listening and speaking skills are also essential to language learners, studies on implications of newly emerging audio-based communication tools are needed. This paper describes an action research project conducted in a Chinese course at Iowa State University (ISU) where an audio-based ...

Development Of An Immersive Game-Based Virtual Reality Training Program To Teach Fire Safety Skills To Children, Emily R. Ericson Jan 2007

Development Of An Immersive Game-Based Virtual Reality Training Program To Teach Fire Safety Skills To Children, Emily R. Ericson

Retrospective Theses and Dissertations

Injuries from residential fires are often overlooked as a dangerous safety concern for children. While lectures and classroom learning techniques can be effective in mitigating this risk, studies have shown that kids retain information better if they are allowed to practice escape techniques. Virtual Reality (VR) has been used both to simulate situations that are too dangerous to practice in real life and as a tool to help children learn. This thesis presents the two stage development of the Fire Safety Project, a game-based VR training environment to increase children's understanding of fire safety. In the first iteration students ...

The Effects Of Digital Audio Files And Online Discussions On Student Proficiency In A Foreign Language, Krista Stutzman Jan 2007

The Effects Of Digital Audio Files And Online Discussions On Student Proficiency In A Foreign Language, Krista Stutzman

Retrospective Theses and Dissertations

One of the biggest struggles a foreign language teacher faces is moving her students from reading and writing in the target language to speaking and listening in the target language. This study focuses on how the use of digital audio files (e.g. Podcasts), online discussions and student anxiety can affect a student's ability to comprehend and speak in a second language. Students gained experience with native speech in the foreign language by listening to weekly audio files and held weekly discussions both in the traditional face-to-face format as well as in online discussions. Students also participated in pre- ...

Native English Speakers' Perceptions Of Intelligibility In The Extended Discourse Produced By Non-Native Speakers, Jiyon Michelle Im Jan 2007

Native English Speakers' Perceptions Of Intelligibility In The Extended Discourse Produced By Non-Native Speakers, Jiyon Michelle Im

Retrospective Theses and Dissertations

In pronunciation, segmental accuracy has been recognized as an important aspect in contributing to a non-native speaker's intelligibility. Nonetheless, there has been a lack of research focusing on the role of segmental errors in understanding extended discourse. Furthermore, previous research studies on intelligibility have largely been conducted in a controlled condition where a listener's cognitive process is more limited than in a real-life setting. In addition, proficiency level has not been considered as one of the factors contributing the intelligibility of non-native speech. This thesis uses a think-aloud methodology to investigate how native English speakers perceived how segmental ...

Program Theory Of A Usda Grants Program For Use In Evaluation Based On Quantitative Content Analysis And Oral History Narrative Analysis, Elena Yu Polush

Retrospective Theses and Dissertations

This research was conceived on the premise that a good evaluation plan for a program begins with explicating the program's essential conceptual underpinnings, namely the program theory. Theory-based evaluation is generally recognized as enhancing the quality of evaluation. However, the theory-based approach remains underutilized in evaluation of federal competitive grants programs. The goal of the research was to depict a coherent description of program theory for the Higher Education Challenge (HEC) grants program grounded on core aspects of theories developed in two studies. The research used quantitative content analysis to systematically study the texts of Request for Application (RFA ...
