The United States government is perennially in need of employees with proficiency in critical foreign languages to communicate with foreign counterparts and maintain relationships worldwide. In order to fulfill this need, the government devotes significant resources training federal employees to advanced levels of language proficiency through…

Epistemic beliefs, epistemic cognitions, and self-regulation processes have a significant role in students' learning. Through this study, I investigated the role of mechanical engineering students' epistemic beliefs and epistemic cognitions involved in self-regulation processes while working on tasks with different difficulty levels. In this…

Computer-supported collaborative learning (CSCL) presents postsecondary educators with a conundrum: how to design and support small-group activities without stifling deep and meaningful learning. The literature indicates that students are not consistently practicing higher-order cognitive activities, educators are not reliably designing or…

This dissertation describes an experiment to investigate how learners with different levels of background in computer science learn core concepts of computer science, in particular, algorithms. We designed a study to focus on cognitive task analysis for eliciting the empirical mental elements of learning two graph algorithms. Cognitive workload…

Two people in the same situation may ascribe very different meanings to their experiences. They will form different awareness, reacting differently to shared information. Various factors can give rise to this behavior. These factors include, but are not limited to, prior knowledge, training, biases, cultural factors, social factors, team vs.…

The purpose of this study was to explore the cognitive adaptation processes of African immigrant women who are professionals. Theories of transformational learning and social cognitive theory were employed to examine cognitive restructuring motivated by learning among women immigrants. The research investigated underlying agentic perspectives and…

People with acquired brain injury (ABI) present with impairments in working memory and executive functions, and these cognitive deficits contribute to difficulty self-regulating the production of expository writing. Cognitive processes involved in carrying out complex writing tasks include planning, generating text, and reviewing or revising text…

Research is not clear on how to address the difficulty students have conceptualizing geologic processes and phenomena. This study investigated how animations coupled with seductive details effect learners' situational interest and emotions. A quantitative quasi-experimental study employing an independent-measures factorial design was used. The…

Cognitive load theory (CLT) (Sweller 1988, 1998, 2010) provides us a guiding framework for designing instructional materials. CLT differentiates three subtypes of cognitive load: intrinsic, extraneous, and germane cognitive load. The three cognitive loads are theorized based on the number of simultaneously processed elements in working memory.…

Communities, also called clusters or modules, are groups of nodes which probably share common properties and/or play similar roles within a graph. They widely exist in real networks such as biological, social, and information networks. Allowing users to interactively browse and explore the community structure, which is essential for understanding…

New technologies and Internet resources are becoming more and more integral to 21st century writing. To write well in the 21st century requires the coordination of new technologies, new skills, and new information. The central challenge to coordinate these new elements of contemporary writing is the deictic influence they have on writing.…

The purpose of this study was to investigate the instructional effectiveness of animated signals among learners with high and low prior knowledge. Each of the two treatments was presented with animated instruction either with signals or without signals on the content of how an airplane achieves lift. Subjects were eighty-seven undergraduate…

Recasts are one type of corrective feedback that reformulates all or part of a learner's erroneous utterance during communicative interaction without changing the meaning. Categorized as implicit and input-providing corrective feedback, recasts have become the focus of debate in the area of interaction research in recent years. The debate…

This research sought to add to a body of knowledge that is severely underrepresented in the scientific literature, reading comprehension in secondary students. Chapter 1 examines the current state of literacy in the nation's public schools and the consequences that arise if students leave high school with inadequate reading skills. It discusses…

Building on previous studies of multiple text reading in history, this study aimed to contribute to that body of work by focusing on non-traditional multimodal sources. In an age of rapidly increasing access to and use of multimodal sources and a demand for reading and comprehending increasingly complex and specialized texts, it appeared there was…
