Computational risk detection holds promise for shielding particularly vulnerable groups from online harm. A thorough literature review on real-time computational risk detection methods revealed that most research defined 'real-time' as approaches that analyze content retrospectively as early as possible or as preventive approaches to prevent risks…

Since socioscientific issues (SSI) are scientific issues situated in the larger society, it is important for many students to understand and effectively communicate information surrounding them. In-class small groups have been used by science instructors to provide students the opportunity to discuss and negotiate difficult SSI. However, learning…

Online learning is increasingly prevalent in higher education. The current study explores how learning takes place in online discussions; an activity often found in online courses. Activity Theory is used to understand the contributions of individuals to the process of socially constructing knowledge within small groups. The Community of Inquiry…

This qualitative case study explored how course context, such as course design, facilitation, and community, supports students' basic psychological needs and thus shapes their situational motivation to participate in asynchronous online discussions in different course contexts. Three upper-level undergraduate courses in different disciplines were…

Studies of interaction in speaking assessment have highlighted problems regarding the unequal distribution of interaction patterns in interviews versus paired formats (Van Lier, 1989; Young & He, 1998). These studies, however, only looked at verbal interaction features, and no attempts in these studies were made to investigate both verbal and…

The present study investigated The Mixxer language exchange site (https://www.language-exchanges.org/) as a typical informal online community of self-directed language learners with a focus on how learners interact with each other. Learners' perception was also studied regarding how their language learning was impacted by their participation in…

A Massive Open Online Course (MOOC) is a course that is offered fully online and is usually open for enrollment by any individual, with no limit on the number of participants. MOOCs are a popular resource for learning worldwide with over 23 million new learners registering for MOOCs in 2017 alone. Coursera, the most popular MOOC platform, has…

This study identified predictors of student perceptions of personal civic responsibility (civic-mindedness) among undergraduate students at the University of Kansas (KU). Using KU-specific data from the 2015 Multi-Institutional Study of Leadership (MSL), relationships between student interaction with specific components of the KU institutional…

Exponential increases in the number of learners receiving instruction through online learning, and institutions using various online modalities for instructional delivery, make salient the need for distance learning policies in higher education, as well as K-12 domains, that focus beyond teacher presence (or student/learner-instructor) and…

Skills associated with collaborative problem solving (CPS), especially in STEM-related disciplines, are increasingly regarded as essential for success in work and life. In the last decade, simulation-based games have emerged as rich environments for the situated learning of such skills, and are instrumental in the study of CPS because they provide…

The dissertation, with a collected papers approach, focused on evaluating the implementation of MI curriculum in high school Biology I classes in south Florida. The dissertation included the development and validation of the Biology Identity and Persistence Survey (BIPS), the connection of instructors' teaching practices with students' biology…

Discourse analysis of literature circles can lead educators to understand the different types of interactions taking place as students talk about text. Social and academic interactions exist in both face-to-face and online discussions of reading material. This study examines two different settings of literature circles and compares interactions of…

This year-long ethnographic study examined teacher and student discourse when interpreting text in a children's philosophy club. Specifically, the study investigated how the opportunities for learning a new discussion form, philosophical conversation, were acted, talked, and written into being as students and their teacher interacted with each…

This dissertation work entails three related studies on the investigation of Peer-Led Guided Inquiry student discourse in a General Chemistry I course through argumentation. The first study, "Argumentation and participation patterns in general chemistry peer-led sessions," is focused on examining arguments and participation patterns in…

This qualitative study explored the experiences of an online learner at a community college. The purpose of the study was to investigate community college students' perception of online courses through an examination of their experiences with online learning. The community of inquiry theory was used as a guide to better understand the importance…
