For this master's thesis, a unique set of cognitive prompts, designed to be delivered through a teachable robotic agent, were developed for students using Tangible Activities for Geometry (TAG), a tangible learning environment developed at Arizona State University. The purpose of these prompts is to enhance the affordances of the tangible learning environment and help researchers to better understand how we can design tangible learning environments to best support student learning. Specifically, the prompts explicitly encourage users to make use of their physical environment by asking students to perform a number of gestures and behaviors while prompting students about domain-specific knowledge. To test the effectiveness of these prompts that combine elements of cognition and physical movements, the performance and behavior of students who encounter these prompts while using TAG will be compared against the performance and behavior of students who encounter a more traditional set of cognitive prompts that would typically be used within a virtual learning environment. Following this study, data was analyzed using a novel modeling and analysis tool that combines enhanced log annotation using video and user model generation functionalities to highlight trends amongst students.

The purpose of this study, originally, was to contribute to the completion of a meta-analysis conducted by Mara Wierstra from the University of Virginia. Wierstra had requested individual participant data from two separate studies conducted in our lab: "Acute bouts of assisted cycling improves cognitive and upper extremity movement functions in adolescents with Down syndrome" and "Assisted Cycling Therapy (ACT) improves inhibition in adolescents with autism spectrum disorder." From the data requested, the participants were required to complete three separate tests (i.e., Tower of London, Trail Making Task and the Stroop Test). After compiling the data and sending it to her, we decided to conduct a small meta-analysis of our own, drawing connecting conclusions from the data from the two studies. We concluded that observationally our data suggest an advantage for ACT over voluntary cycling and no cycling across two separate populations (i.e., Autism Spectrum Disorder and Down syndrome), and across different measures of executive function (i.e., Stroop Test, Trail Making Test, and Tower of London). The data suggest that the ACT interventions may promote the upregulation of neurotropic factors leading to neurogenesis in the prefrontal cortex of the brain.

In this study, the oppositional processes theory was proposed to suggest that reliance on semantic and episodic memory systems hinder originality during idea generation for divergent thinking tasks that are generally used to assess creative potential. In order to investigate the proposed oppositional processes theory, three experiments that manipulated the memory accessibility in participants during the alternative uses tasks were conducted. Experiment 1 directly instructed participants to either generate usages based on memory or not from memory; Experiment 2 provided participants with object cues that were either very common or very rare in daily life (i.e., bottle vs. canteen); Experiment 3 replicated the same manipulation from Experiment 2 with much longer generation time (10 minutes in Experiment 2 vs. 30 minutes in Experiment 3). The oppositional processes theory predicted that participants who had less access to direct and unaltered usages (i.e., told to not use memory, were given rare cues, or were outputting items later in the generation period) during the task would be more creative. Results generally supported the predictions in Experiments 1 and 2 where participants from conditions which limited their access to memory generated more novel usages that were considered more creative by independent coders. Such effects were less prominent in Experiment 3 with extended generation time but the trends remained the same.

Many English Language Learner (ELL) children struggle with knowledge of vocabulary and syntax. Enhanced Moved by Reading to Accelerate Comprehension in English (EMBRACE) is an interactive storybook application that teaches children to read by moving pictures on the screen to act out the sentences in the text. However, EMBRACE presents the same level of text to all users, and it is limited in its ability to provide error feedback, as it can only determine whether a user action is right or wrong. EMBRACE could help readers learn more effectively if it personalized its instruction with texts that fit their current reading level and feedback that addresses ways to correct their mistakes. Improvements were made to the system by applying design principles of intelligent tutoring systems (ITSs). The new system added features to track the student’s reading comprehension skills, including vocabulary, syntax, and usability, based on various user actions, as well as features to adapt text complexity and provide more specific error feedback using the skills. A pilot study was conducted with 7 non-ELL students to evaluate the functionality and effectiveness of these features. The results revealed both strengths and weaknesses of the ITS. While skill updates appeared most accurate when users made particular kinds of vocabulary and syntax errors, it was not able to correctly identify other kinds of syntax errors or provide feedback when skill values became too high. Additionally, vocabulary error feedback and adapting the complexity of syntax were helpful, but syntax error feedback and adapting the complexity of vocabulary were not as helpful. Overall, children enjoy using EMBRACE, and building an intelligent tutoring system into the application presents a promising approach to make reading a both fun and effective experience.
