Description
With the overall health of the environment rapidly declining \u2014 mostly due to human behaviors, solving the problem of nature deficit disorder and getting more children interested and aware of nature could be paramount to improving the environmental health of our planet. In this study, the relationship between children's learning and emotion is explored. Pre- and post-tests were given to children attending a week-long summer freshwater ecology camp; their knowledge of and emotional connection to different ecological concepts were measured. Two separate ecosystems were tested \u2014 a freshwater ecosystem that was taught over the course of the week, and a marine ecosystem for comparison. Increases in knowledge and emotion were seen in every freshwater ecosystem concept. Additionally, the knowledge and emotion scores were correlated, suggesting a positive relationship between them. The marine ecosystem did not show improvements in concrete knowledge, but showed increases in abstract learning, indicating that the abstract concepts learned about the freshwater ecosystem were able to transfer to the marine. Overall results show the ability of a hands-on learning experience to foster an emotional connection between a child and the subject matter. However, long-term studies are needed to track the relationship between children and their knowledge of and emotional connection to the subject matter.

Description
Education plays a key role throughout many different fields of study. My question has to do with not what we are learning, but how we are learning it, therefore focusing more on the teaching and instructional design aspect of the learning process. Specifically, the goal of my thesis is to theoretically define collaborative learning and develop a framework that demonstrates how collaboration and interactivity can be successfully implemented in a language learning classroom. Language learning is essential in schools because it enables students to be culturally aware. According to the Modern Language Teachers' Association of South Australia, language learning plays a significant role in 21st Century learning. It assists students in being more community engaged as well as culturally diverse. They state that "knowing additional languages and cultures involves connecting, engaging, and interacting with others and negotiating boundaries based on diverse ways of understanding the world." (MLTASA) Collaboration can be very beneficial in the human learning process. According to Webb, students that collaborate with each other engage in challenging conversations and produce joint solutions whereas students that don't collaborate engage in conversation about practical rather than abstract matters (Webb, 2009). The success of collaboration is defined by the content of the dialog, groups won't necessarily engage in beneficial dialogue without help and facilitation by the teacher. It's important for teachers to keep groups on task and monitor their progress throughout the lesson. Through collaborative learning the student is able to take more from the lesson and view each concept from an alternate perspective. With teacher facilitated group discussions, students preform knowledge construction and challenge individual thoughts in order to come up with a joint solution that's takes everyone's point of view into perspective (Nastasi, 1999). Many researchers have concluded that collaborative learning, is a very beneficial learning method when it comes to challenging thoughts and concepts between students. Because each individual has a different thought process and ideas, each student brings a different concept that can be challenged and discussed among the group. Many researchers have previously studied the benefits of collaborative learning as well as the teacher's role in correctly facilitating and implementing it. Webb, highlights the importance of teachers actively pushing students to collaborate and challenge ideas. She states "In classrooms in which teachers pushed students to make explicit the steps in their mental processes (whether students' answers and strategies were correct or incorrect), collaborative groups engaged in frequent explaining and provided explanations that were correct and complete" (Webb, 2009, pg.18). Similarly, researchers such as Rijkje Dekker and Marianne Elshout-Mohr argue that collaboration in classrooms is especially important in terms of the type of work that is assigned. Assignments that require collaboration generally go more in depth and are considered more challenging than those given in individual assignments "Collaborative learning tasks are in general designed as complex, challenging and authentic problems. Such problems motivate students to attempt different strategies and co-construct and justify solutions" (Elshout-Mohr and Dekker, 2000, pg.40). Collaboration in language learning classrooms is beneficial and quite easy to implement (Elshout-Mohr and Dekker, 2000).

Description
Distributed self-assessments and reflections empower learners to take the lead on their knowledge gaining evaluation. Both provide essential elements for practice and self-regulation in learning settings. Nowadays, many sources for practice opportunities are made available to the learners, especially in the Computer Science (CS) and programming domain. They may choose to utilize these opportunities to self-assess their learning progress and practice their skill. My objective in this thesis is to understand to what extent self-assess process can impact novice programmers learning and what advanced learning technologies can I provide to enhance the learner’s outcome and the progress. In this dissertation, I conducted a series of studies to investigate learning analytics and students’ behaviors in working on self-assessments and reflection opportunities. To enable this objective, I designed a personalized learning platform named QuizIT that provides daily quizzes to support learners in the computer science domain. QuizIT adopts an Open Social Student Model (OSSM) that supports personalized learning and serves as a self-assessment system. It aims to ignite self-regulating behavior and engage students in the self-assessment and reflective procedure. I designed and integrated the personalized practice recommender to the platform to investigate the self-assessment process. I also evaluated the self-assessment behavioral trails as a predictor to the students’ performance. The statistical indicators suggested that the distributed reflections were associated with the learner's performance. I proceeded to address whether distributed reflections enable self-regulating behavior and lead to better learning in CS introductory courses. From the student interactions with the system, I found distinct behavioral patterns that showed early signs of the learners' performance trajectory. The utilization of the personalized recommender improved the student’s engagement and performance in the self-assessment procedure. When I focused on enhancing reflections impact during self-assessment sessions through weekly opportunities, the learners in the CS domain showed better self-regulating learning behavior when utilizing those opportunities. The weekly reflections provided by the learners were able to capture more reflective features than the daily opportunities. Overall, this dissertation demonstrates the effectiveness of the learning technologies, including adaptive recommender and reflection, to support novice programming learners and their self-assessing processes.

Description
Previous research has showed that auditory modulation may be affected by pure tone
stimuli played prior to the onset of speech production. In this experiment, we are examining the
specificity of the auditory stimulus by implementing congruent and incongruent speech sounds in
addition to non-speech sound. Electroencephalography (EEG) data was recorded for eleven adult
subjects in both speaking (speech planning) and silent reading (no speech planning) conditions.
Data analysis was accomplished manually as well as via generation of a MATLAB code to
combine data sets and calculate auditory modulation (suppression). Results of the P200
modulation showed that modulation was larger for incongruent stimuli than congruent stimuli.
However, this was not the case for the N100 modulation. The data for pure tone could not be
analyzed because the intensity of this stimulus was substantially lower than that of the speech
stimuli. Overall, the results indicated that the P200 component plays a significant role in
processing stimuli and determining the relevance of stimuli; this result is consistent with role of
P200 component in high-level analysis of speech and perceptual processing. This experiment is
ongoing, and we hope to obtain data from more subjects to support the current findings.

Description
Previous research demonstrated the overall efficacy of an embodied language intervention (EMBRACE) that taught pre-school children how to simulate (imagine) language in a heard narrative. However, EMBRACE was not effective for every child. To try to explain this variable response to the intervention, the video recordings made during the four-day intervention sessions were assessed and emotion was coded. Each session was emotion-coded for child emotions and for child-researcher emotions. The child specific emotions were 1) engagement in the task, this included level of participation in the activity, 2) motivation/attention to persist and complete the task, as well as stay focused, and 3) positive affect throughout the session. The child-researcher specific emotions were 1) engagement with each other, this involved how the child interacted with the researcher and under what context, and 2) researcher’s positive affect, this incorporated how enthusiastic and encouraging the researcher was throughout the session. It was hypothesized that effectiveness of the intervention would be directly correlated with the degree that the child displayed positive emotions during the intervention. Thus, the analysis of these emotions should highlight differences between the control and EMBRACE group and help to explain variability in effectiveness of the intervention. The results did indicate that children in the EMBRACE group generally had a significantly higher positive affect compared to the control group, but these results did not influence the ability for the child to effectively recall or moderate the EEG variables in the post-test. The results also showed that children who interacted with the researcher more tended to be in the EMBRACE group, whereas children who did not interact with the researcher more frequently were in the control group, showing that the EMBRACE intervention ended up being a more collaborative task.

Description
In the study of the human brain’s ability to multitask, there are two perspectives: concurrent multitasking (performing multiple tasks simultaneously) and sequential multitasking (switching between tasks). The goal of this study is to investigate the human brain’s ability to “multitask” with multiple demanding stimuli of approximately equal concentration, from an electrophysiological perspective different than that of stimuli which don’t require full attention or exhibit impulsive multitasking responses. This study investigates the P3 component which has been experimentally proven to be associated with mental workload through information processing and cognitive function in visual and auditory tasks, where in the multitasking domain the greater attention elicited, the larger P3 waves are produced. This experiment compares the amplitude of the P3 component of individual stimulus presentation to that of multitasking trials, taking note of the brain workload. This study questions if the average wave amplitude in a multitasking ERP experiment will be the same as the grand average when performing the two tasks individually with respect to the P3 component. The hypothesis is that the P3 amplitude will be smaller in the multitasking trial than in the individual stimulus presentation, indicating that the brain is not actually concentrating on both tasks at once (sequential multitasking instead of concurrent) and that the brain is not focusing on each stimulus to the same degree when it was presented individually. Twenty undergraduate students at Barrett, the Honors College at Arizona State University (10 males and 10 females, with a mean age of 18.75 years, SD= 1.517) right handed, with normal or corrected visual acuity, English as first language, and no evidence of neurological compromise participated in the study. The experiment results revealed that one- hundred percent of participants undergo sequential multitasking in the presence of two demanding stimuli in the electrophysiological data, behavioral data, and subjective data. In this particular study, these findings indicate that the presence of additional demanding stimuli causes the workload of the brain to decrease as attention deviates in a bottleneck process to the multiple requisitions for focus, indicated by a reduced P3 voltage amplitude with the multitasking stimuli when compared to the independent. This study illustrates the feasible replication of P3 cognitive workload results for demanding stimuli, not only impulsive-response experiments, to suggest the brain’s tendency to undergo sequential multitasking when faced with multiple demanding stimuli. In brief, this study demonstrates that when higher cognitive processing is required to interpret and respond to the stimuli, the human brain results to sequential multitasking (task- switching, not concurrent multitasking) in the face of more challenging problems with each stimulus requiring a higher level of focus, workload, and attention.

Description
Transcranial Current Stimulation (TCS) is a long-established method of modulating neuronal activity in the brain. One type of this stimulation, transcranial alternating current stimulation (tACS), is able to entrain endogenous oscillations and result in behavioral change. In the present study, we used five stimulation conditions: tACS at three different frequencies (6Hz, 12Hz, and 22Hz), transcranial random noise stimulation (tRNS), and a no-stimulation sham condition. In all stimulation conditions, we recorded electroencephalographic data to investigate the link between different frequencies of tACS and their effects on brain oscillations. We recruited 12 healthy participants. Each participant completed 30 trials of the stimulation conditions. In a given trial, we recorded brain activity for 10 seconds, stimulated for 12 seconds, and recorded an additional 10 seconds of brain activity. The difference between the average oscillation power before and after a stimulation condition indicated change in oscillation amplitude due to the stimulation. Our results showed the stimulation conditions entrained brain activity of a sub-group of participants.

Description
Introduction: The Eye to Eye mentorship program is a national program in which college or high school students with learning differences mentor middle school students with learning differences. There are 68 Eye to Eye programs around the country, but little research has been done on their effectiveness and how to improve it. We conducted and evaluated one program site at Arizona State University and implemented this mentorship program for the first time during 2019. We hypothesized the Eye to Eye mentorship program that paired college students who have learning differences with middle school students who have similar learning differences would improve the outcomes and socio-behavior skills of both mentors and mentees.
Methods: The Eye to Eye mentorship program assessed involved mentors and mentees who completed 12 in-person art sessions out of the normal 20 in-person sessions. The first main assessment was the BLD (Breger Learning Difference) Feedback Survey addressing one’s experience in the Eye to Eye program and which were completed at the end of the mentorship program and filled out by mentors, mentees, and mentees parents (one parent for each mentee). A total of 12 mentors, 6 mentees, and 6 mentee parents were included in the feedback survey final analysis. The second main assessments were the pre and post Behavior Assessment System for Child, Third Edition (BASC-3) provided to mentors, mentees, and mentees parents (one parent for each mentee). A total of 10 mentors, 5 mentees, and 5 mentee parents were included in pre and post BASC-3 final analysis. Fall 2019 (pre) and Spring 2020 (post) optional interviews involved 5 mentors and 3 mentees who showed interest and were comfortable participating with additional release forms.
Results: The program was generally positively rated in the feedback survey by mentors, mentees, and mentee parents. The highest responses for mentors, mentees, and mentee parents all incorporated average ratings of 4.0 or higher (out of 5.0) for perceived understanding of socio-emotional skills after Eye to Eye, experience in Eye to Eye, how having a mentor or mentee made them feel, and perceived change in self-awareness. All three groups reported fairly high ratings of improved self-awareness of 4.0/5.0 or above. No negative ratings were provided by any participants and the lowest response was no change. The BASC-3 evaluation found statistically significant improvement in mentors’ anxiety and atypicality and mentees’ sense of inadequacy.
Discussion: The Eye to Eye program was popular and well-rated despite only involving 12 in- person one-hour art sessions. The mentors, mentees, and mentee parents felt positive about the Eye to Eye program when answering the feedback survey. Some suggestions are made on how to improve this program to better enhance someone with learning differences future ability to succeed. Future research is needed to assess the true impact due to the COVID-19 epidemic and other limitations.

Description
The purpose of this project was to extend Whitehead 2016 to determine what neural substrates supported conflict-mediated learning. Unfortunately, as a result of the COVID-19 pandemic we were unable to address this. To repurpose the collected data, an analysis of which features of the Flanker task subjects were learning was conducted. Specifically, we wanted to know if subjects were learning by using the flanking stimuli to predict the central target or vice versa. Over 14 blocks comprised of 120 trials, we found that subjects made more stroop errors than flanker and target errors, indicating subjects were responding to stimuli in context of the flanker rather than the stroop effect.
