An Adaptive Computational System For Automated, Learner-Customized Segmental Perception Training In Words And Sentences: Design, Implementation, Assessment, Manman Qian Jan 2018

An Adaptive Computational System For Automated, Learner-Customized Segmental Perception Training In Words And Sentences: Design, Implementation, Assessment, Manman Qian

Graduate Theses and Dissertations

Segmental perception training is important as many phonemic errors are common in second language pronunciation and the perception of foreign phonemic contrasts is often difficult to acquire without instruction (Best & Tyler, 2007; Birdsong, 1992, 2006; Flege, 1988, 1995). Numerous computer-assisted programs exist that provide training for segmental perception, but few of them have made effective use of already-existing language resources. There has been a call for the creation of a computer-assisted pronunciation teaching (CAPT) program that provides individualized needs-based training based on first language and learner proficiency (Levis, 2007; Munro, Derwing, & Thomson, 2015). A perception training model is yet to be developed that takes into account the major components important to intelligibility, the use of technology, and the state-of-the-art research findings on perception training. Specifically, the ideal training model first needs to account for learners’ L1 backgrounds since L2 segmental errors are often L1-specific (Swan & Smith, 2002). Second, the training model should also be tailored to individual needs as not everyone sharing the same L1 will certainly have the L1-predicted errors (Munro, 2018; Munro, Derwing, & Thomson, 2015). Third, the functional load theory (King, 1967) suggests that not all phonemic errors affect intelligibility equally and that perception training should not target all errors as if they had an equal impact on intelligibility. Fourth, the training model should leverage a high-variability phonetic training design, defined as a technique of using multiple voice models for perception training (Pisoni & Lively, 1995), which has been found to be efficacious in improving perception (Thomson, 2012; Wang & Munro, 2004) as well as production (Thomson, 2011).

This study introduces an innovative online perception training system that uses computational approaches to deliver high variability phonetic training designed to improve learners’ ability to discriminate and identify segmental contrasts. The system was designed with five major features. First, the system was developed with intelligibility-driven goals by only focusing on high functional load segmental errors. Second, the system offered training customized to individual learners’ pre-training diagnostic performance and then adapted the training content and intensity based on individual learners’ errors during real-time learning. Third, in recognition of the efficacy of multi-voice models for perception acquisition (Thomson, 2011, 2012; Wang & Munro, 2004), the system utilized high-variability phonetic ...


Teaching Structural Analysis With A Mobile Augmented Reality Application, Suhan Yao Jan 2018

Teaching Structural Analysis With A Mobile Augmented Reality Application, Suhan Yao

Graduate Theses and Dissertations

Structural analysis is a core course taught in every undergraduate civil engineering program and most architectural and construction engineering programs. Despite the critical role of this subject matter in engineering education, students usually have difficulty in grasping the abstract concepts, visualizing the deformed shape of simple structures, and relating basic structural members to more complex structural systems such as buildings and bridges. To help students to visualize the structural behaviors as well as linking structural representations with physical structures, a mobile augmented reality (AR) application, iStructAR, was developed. Through the application, a real campus building is superimposed with a virtual ...

Modes Of Feedback In Esl Writing: Implications Of Shifting From Text To Screencast, Kelly J. Cunningham Jan 2017

Modes Of Feedback In Esl Writing: Implications Of Shifting From Text To Screencast, Kelly J. Cunningham

Graduate Theses and Dissertations

For second language writing (SLW) instructors, decisions regarding technology-mediated feedback are particularly complex as they must also navigate student language proficiency, which may vary across different areas such as reading or listening. Yet technology-mediated feedback remains an underexplored realm in SLW especially with regard to how modes of technology affect feedback and how students interact with and understand it. With the expanding pervasiveness of video and increased access to screencasting (screen recording), SLW instructors have ever-growing access to video modes for feedback, yet little research to inform their choices. Further, with video potentially requiring substantial investment from institutions through hosting ...

The present study seeks to expand the existing literature on video game effects by focusing on a rarely-tested outcome: creative production.

As a game with few rules and a high amount of player freedom, Minecraft exemplifies a game that fosters players’ abilities for creative expression. This experimental study compares the ...


Developing Interactive Learning For Environmental Issues, Meriesa C. Elliott Jan 2016

Developing Interactive Learning For Environmental Issues, Meriesa C. Elliott

Graduate Theses and Dissertations

The environment is being negatively affected by the behavior of human beings. Climate change, while a natural occurrence, is happening at an unnatural pace, sped up by human actions. Even with these things in mind, it seems an impossible task to get people to move toward positive environmental impacts. While many people are aware of environmental issues, they don’t fully understand what actions are contributing to the problems, what alternative options they have, or how they can help alleviate the problem. With that in mind, I examine how effective interactive design can be at creating a learning environment by ...

A Systemic Functional Perspective On Automated Writing Evaluation: Formative Feedback On Causal Discourse, Aysel Saricaoglu Jan 2015

A Systemic Functional Perspective On Automated Writing Evaluation: Formative Feedback On Causal Discourse, Aysel Saricaoglu

Graduate Theses and Dissertations

Making explanations is a very important communicative function in academic literacy; several disciplines including science are dominated by causal explanations (Mohan & Slater, 2004; Slater, 2004; Wellington & Osborne, 2001). For academic success, students need to write about causes and effects well with the help of their instructors, which means that formative assessment of causal discourse is necessary (Slater & Mohan, 2010). However, manual evaluation of causal discourse is time-consuming and impractical for writing instructors. For this reason, automated evaluation of causal discourse, which current automated writing evaluation (AWE) systems cannot perform, is required. Addressing these needs, this dissertation aimed to develop an automated causal ...

Understanding The Role Of The Modality Principle In Multimedia Learning Environments, Amy Marie Oberfoell Jan 2015

Understanding The Role Of The Modality Principle In Multimedia Learning Environments, Amy Marie Oberfoell

Graduate Theses and Dissertations

The modality principle was first addressed in 1989 by Mayer and Moreno. The modality principle asserts presenting words as speech, rather than on-screen text, is more effective for the learner. The modality principle states that learners are more successful with understanding information that uses narration than on-screen text because the on-screen text may produce a cognitive overload if it is accompanied by other visual elements. This overload may occur due to the learner needing to give attention to the visual graphic/image as well as provide visual attention to the on-screen text. However, if the on-screen text is narrated, the ...
