This doctoral dissertation explores diverse facets of online research and comprehension among college students with English as a second or foreign language (L2 students). The research involves three distinct investigations within this overarching theme. Firstly, the study delves into the online reading and writing practices employed by Korean L2…

Sense-making theory involves a sociological/communications science approach to the need of students to make sense of their environment and the information they are seeking to find. With many digital resources to choose from, non-traditional students often have difficulty finding the best resource for their assignments, opting for the easiest path…

The field of game-mediated L2 learning has grown exponentially, and much has been discovered about the potentials of game-mediated interactions for L2 development, yet the fine-grained dynamics of player-game interactions and how they come to facilitate and afford L2 development are still largely underexplored. To address this gap in the…

This study aims to investigate users' search tactic application and system support in using digital libraries. A user study was conducted with sixty digital library users. The study was designed to answer three research questions: 1) How do users engage in a search process by applying different types of search tactics while conducting different…

This study examined L2 (German) awareness in intermediate American college learners of German through their judgments of 15 texts that had been authored by either native speakers (NS) or non-native speakers (NNS) or had been created through Web-Based Machine Translation (WBMT). The specific objectives sought to investigate: (a) how learners…

The present study built upon an earlier study by Ebner and Ehri (in press), which examined the Internet's potential as a learning tool for enhancing college students' vocabularies. The current research sought to extend that study by determining how to make online vocabulary learning more effective. An experiment was conducted to investigate a…

Students who harbor misconceptions often find chemistry difficult to understand. To improve teaching about the dissolving process, first semester introductory chemistry students were asked to complete a free-response questionnaire on writing balanced equations for dissolving ionic compounds in water. To corroborate errors and misconceptions…

Reading comprehension of school-aged students is an important topic of research; however, research on the reading comprehension of adult foreign/second language learners whose first language is English is limited, especially studies investigating the reading comprehension strategies that readers of different proficiency levels use when they…

Since the mid-1990s, the link between recasts and L2 development has been extensively tested, and the results from those studies have largely demonstrated that recasts have a positive effect on L2 learning. With this firm support from previous empirical evidence, studies have begun to focus on how recasts assist learning and under what conditions…

In this study, the effectiveness of worked examples that emphasizes problem features (data type, number of groups, purpose of analysis) associated with specific problem types (t-test, chi-square, correlation) were examined on students' construction of problem schemata compared to traditional solution-only worked examples. A sample of 96 students…

This study reports the results of the first systematic investigation into Astro 101 students' conceptual and reasoning difficulties with cosmology. We developed four surveys with which we measured students' conceptual knowledge of the Big Bang, the expansion and evolution of the universe, and the evidence for dark matter. Our classical test theory…

The purpose of this study is to explore ways of incorporating web-based concordancers for the purpose of teaching English collocations. A mixed-methods design utilizing a case study strategy was employed to uncover four specific dimensions of corpus use by twenty-four students in two classroom sections of a writing course at a university in…

Effective listening comprehension skills are important as the world becomes increasingly global and television, radio, and the Internet become forums for English communication. However, many countries, such as Tunisia, do not use English as a first or second language, but as a foreign language. Therefore, realizing the importance of English, the…

Women in the U.S. and all over the world are more vulnerable to HIV/AIDS because of both behavioral and contextual factors. HIV/AIDS prevention education on government health websites plays an important role in reducing this health inequality for women. However, contrary to the assumption of Rimal and Real's (2003) Risk Perception Attitude…

The main purpose of this study was to compare the strategies used by Chinese-speaking students when confronted with familiar versus unfamiliar topics in a multiple-choice format reading comprehension test. The focus was on describing what students do when they are taking reading comprehension tests by asking students to verbalize their thoughts.…
