This study investigated the effects of concurrent audio and equivalent onscreen text on the ability of learners of English as a foreign language (EFL) to form associations between textual and aural forms of target vocabulary words. The study also looked at the effects of learner control over an audio sequence on the association of textual and aural forms of target words. Attitudes towards experimental treatments and reported level of cognitive load were also examined in the context of a computer-based multimedia instructional program. A total of 200 college students took part in the study. Participants were randomly assigned to experimental conditions in a 2 x 3 factorial design with level of learner control (learner-controlled vs. not-learner-controlled) and format of presentation of information (audio + no text vs. audio + full text vs. audio + keyword text) as factors. The subjects completed a pretest, a posttest, cognitive load questions, and an attitude questionnaire. The results revealed the following findings: (a) groups in the audio + keyword text conditions outperformed those in the audio + no text and audio + full text conditions on text-sound association, (b) within the audio + keyword text conditions, the learner-controlled group outperformed the not-learner-controlled group on text-sound association, (c) within the learner-controlled conditions, the audio + keyword group outperformed the audio + no text and audio + full text groups on text-sound association, (d) a redundancy effect was not found for any treatment condition, and (e) overall, participants had positive attitudes towards the treatments. Implications, limitations, and future directions are discussed within the frameworks of cognitive load theory and cognitive theory of multimedia learning.

This study aims to uncover whether English Central, an online English as a Second Language tool, improves speaking proficiency for undergraduate students with developing English skills. Eighty-three advanced English language learners from the American English and Culture Program at Arizona State University were randomly assigned to one of three conditions: the use of English Central with a learner-control, shared-control, and a no-treatment condition. The two treatment groups were assigned approximately 14.7 hours of online instruction. The relative impact of each of the three conditions was assessed using two measures. First, the Pearson Versant Test (www.versanttest.com), a well-established English-as-a-second-language speaking test, was administered to all of the participants as a pre- and post-test measure. Second, students were given a post-treatment questionnaire that measured their motivation in using online instruction in general, and English Central specifically. Since a significant teacher effect was found, teachers involved in this study were also interviewed in order to ascertain their attitude toward English Central as a homework tool. Learner outcomes were significantly different between the shared and learner conditions. Student motivation was predictive of learning outcomes. Subjects in the shared condition outperformed those in the learner condition. Furthermore, those in the shared condition scored higher than the control condition; however, this result did not reach statistical significance. Results of the follow-up teacher survey revealed that while a teacher's view of the tool (positive or negative), was not a predictor of student success, teacher presentation of the tool may lead to a significant impact on student learning outcomes.

This research study investigated the effects of high fidelity graphics on both learning and presence, or the "sense of being there," inside a Virtual Learning Environment (VLE). Four versions of a VLE on the subject of the element mercury were created, each with a different combination of high and low fidelity polygon models and high and low fidelity shaders. A total of 76 college age (18+ years of age) participants were randomly assigned to one of the four conditions. The participants interacted with the VLE and then completed several posttest measures on learning, presence, and attitudes towards the VLE experience. Demographic information was also collected, including age, computer gameplay experience, number of virtual environments interacted with, gender and time spent in this virtual environment. The data was analyzed as a 2 x 2 between subjects ANOVA.

The main effects of shader fidelity and polygon fidelity were both non- significant for both learning and all presence subscales inside the VLE. In addition, there was no significant interaction between shader fidelity and model fidelity. However, there were two significant results on the supplementary variables. First, gender was found to have a significant main effect on all the presence subscales. Females reported higher average levels of presence than their male counterparts. Second, gameplay hours, or the number of hours a participant played computer games per week, also had a significant main effect on participant score on the learning measure. The participants who reported playing 15+ hours of computer games per week, the highest amount of time in the variable, had the highest score as a group on the mercury learning measure while those participants that played 1-5 hours per week had the lowest scores.

This experimental pretest-posttest design study extended the field of media literacy research to pre-professionals in the entertainment industry. Specifically, it investigated the effects of lecture, film screenings and focused discussions on media literacy general awareness, comprehension, critical thinking and attitudes about filmmakers' responsibility after a unit of instruction on media violence designed specifically for university film majors.

Inherent in this process was an attempt to create a valid instrument for measuring media literacy awareness, comprehension, critical thinking and attitudes about social responsibilities among future media makers. Items were presented from the perspective of a creator of entertainment products. A demographic survey was used to collect data on past media literacy education and media viewing habits of this niche group, while evaluation data provided insights into the thought processes of students as they considered issues of media literacy -- sometimes for the first time -- in their own lives, in the lives of others, and in their future careers. Factorial analysis was used to test the effectiveness of the instrument. Analyses of variance were employed to measure pretest-posttest differences in treatment groups and Paired Samples T-tests to measure differences across the entire sample. Responses to open-ended evaluation questions were analyzed and coded and presented by item.

Results showed positive changes in comprehension and filmmaker responsibility attitudes across treatment groups and significant positive differences in media awareness and critical thinking among students across treatment groups. Results did not align with treatment groups: the students who watched film clips and participated in focused discussions gained knowledge but did not achieve significantly greater mean scores than those who did not participate in these treatments.

Findings support those in the research literature that holistic media literacy instruction, which incorporates aspects of creating as well as consuming entertainment products, can open new pathways of criticality about media issues. Media should be presented in context and with direction from the instructor. In eight evaluation items, some 90% of the young media makers agreed that the media violence lesson influenced their thinking and that they would consider material taught in this lesson when creating future media products.

This dissertation study quantitatively measured the performance of 345 students who received public speaking instruction through an online platform presented in one of six experimental conditions in order to explore the ability of online lectures to replicate the characteristics of instructor presence and learner interaction traditionally associated with face-to-face public speaking courses. The study investigated the following research questions:

RQ1: How does the visibility of an instructor in a public speaking video lesson affect students' perception of presence?

RQ2: How does the visibility of an instructor in a public speaking video lesson affect student learning?

RQ3: How do self-explanation (Constructive) and note-taking (Active) types of learning activities affect students' perception of presence compared to passive lessons when presented in a video lesson?

RQ4: How do self-explanation (Constructive) and note-taking (Active) types of learning activities affect student learning compared to passive lessons when presented in a video lesson?

Additionally, the study collected qualitative feedback from participants on their experience in order to improve understanding of how to effectively design lectures for public speaking courses.

Results of the study were unable to statistically distinguish between students assigned to treatments that varied in both modality and level of activity. However, a significant finding of this study is that learning gains and students' perception of instructor presence were positive across all conditions.

The lack of significant differences by treatment indicates that the design attributes at the center of the study may be unnecessary considerations for developing content for online learning. Consequently, the improved performance of participants regardless of their assigned treatment in this study identifies a limitation to the application of Media Equation Theory and the Interactive-Constructive-Active-Passive (ICAP) Framework for designing online learning content for public speaking students as well as identifies two key implications: 1) exposure to an online lesson can increase learning; and 2) exposure to an online lesson can serve as a cost-effective alternative for producing lessons in public speaking courses.

Unschooling is a child-centered educational philosophy that eschews teachers,

schools, curricula, grades and tests. Unschool practitioners have complete freedom to choose what they want to learn, when, to what level, and for how long. Unschooling families use the World Wide Web to provide a bespoke academic experience at home. This study compares qualitative data collected from questionnaires and semi-structured interviews conducted with 10 unschooling families with quantitative data collected from 5 children within these families using a tracking and monitoring software. The software captured the duration of use, keystrokes, mouseclicks, and screenshots for all programs and websites for 14 days. Children stated they used technology less than 6 hours a day, and parents stated children used them less than 8 hours a day. Quantitative data shows the children use technology at least 10 hours a day, suggesting usage self-reports may not be reliable. The study revealed hardware form factor was the number one determinate of application use. Almost exclusively social media was used on smartphones, internet browsing on tablets, and creative endeavors such as modding, hacking, fan fiction writing, and video game level building all took place exclusively on laptops and desktops. Concurrent use of differing hardware form factors was the norm observed. Participants stated YouTube, Wikipedia and Khan Academy were the websites most used for knowledge gathering. The tracking software verified YouTube and Wikipedia were the most used websites, however when accessed on the PC, those sites were used almost exclusively for video game related purposes. Over 90% of the total PC use was spent on video games. More traditional educational activities were done primarily on tablets and on parent smartphones with parental engagement. Khan Academy was not used by the

participants in the 14 day monitoring period. 90 day web browser logs indicated Khan Academy was used by individuals no more than 3 times in a 90 day period,

demonstrating the inherent risks in relying upon internet usage self-reports without

quantitative software for verification. Unschooling children spent between 30 and 60 hours a week using technology.

Writing instruction poses both cognitive and affective challenges, particularly for adolescents. American teens not only fall short of national writing standards, but also tend to lack motivation for school writing, claiming it is too challenging and that they have nothing interesting to write about. Yet, teens enthusiastically immerse themselves in informal writing via text messaging, email, and social media, regularly sharing their thoughts and experiences with a real audience. While these activities are, in fact, writing, research indicates that teens instead view them as simply "communication" or "being social." Accordingly, the aim of this work was to infuse formal classroom writing with naturally engaging elements of informal social media writing to positively impact writing quality and the motivation to write, resulting in the development and implementation of Sparkfolio, an online prewriting tool that: a) addresses affective challenges by allowing students to choose personally relevant topics using their own social media data; and b) provides cognitive support with a planner that helps develop and organize ideas in preparation for writing a first draft. This tool was evaluated in a study involving 46 eleventh-grade English students writing three personal narratives each, and including three experimental conditions: a) using self-authored social media post data while planning with Sparkfolio; b) using only data from posts authored by one's friends while planning with Sparkfolio; and c) a control group that did not use Sparkfolio. The dependent variables were the change in writing motivation and the change in writing quality that occurred before and after the intervention. A scaled pre/posttest measured writing motivation, and the first and third narratives were used as writing quality pre/posttests. A usability scale, logged Sparkfolio data, and qualitative measures were also analyzed. Results indicated that participants who used Sparkfolio had statistically significantly higher gains in writing quality than the control group, validating Sparkfolio as effective. Additionally, while nonsignificant, results suggested that planning with self-authored data provided more writing quality and motivational benefits than data authored by others. This work provides initial empirical evidence that leveraging students' own social media data (securely) holds potential in fostering meaningful personalized learning.

The purpose of this study was to investigate the impacts of visual cues and different types of self-explanation prompts on learning, cognitive load and intrinsic motivation, as well as the potential interaction between the two factors in a multimedia environment that was designed to deliver a computer-based lesson about the human cardiovascular system. A total of 126 college students were randomly assigned in equal numbers (N = 21) to one of the six experimental conditions in a 2 X 3 factorial design with visual cueing (visual cues vs. no cues) and type of self-explanation prompts (prediction prompts vs. reflection prompts vs. no prompts) as the between-subjects factors. They completed a pretest, subjective cognitive load questions, intrinsic motivation questions, and a posttest during the course of the experience. A subsample (49 out of 126) of the participants' eye movements were tracked by an eye tracker. The results revealed that (a) participants presented with visually cued animations had significantly higher learning outcome scores than their peers who viewed uncued animations; and (b) cognitive load and intrinsic motivation had different impacts on learning in multimedia due to the moderation effect of visual cueing. There were no other significant findings in terms of learning outcomes, cognitive load, intrinsic motivation, and eye movements. Limitations, implications and future directions are discussed within the framework of cognitive load theory, cognitive theory of multimedia learning and cognitive-affective theory of learning with media.

Online teacherpreneurs are current and former PreK-12 teachers who share their original classroom resources in online marketplaces where teachers download them for a small fee. Online teacherpreneurs’ resources are becoming prolific in classrooms today. Meanwhile, online teacherpreneurs stand to gain financially and professionally. This exploratory study drew on conceptual frameworks from entrepreneurship and teacher leadership to describe the practice of online teacherpreneurship in terms of the characteristics of the people who participate, the school environments in which they work, and the possible impacts they experience. An exploratory sequential mixed methods design was used. In phase one, 10 semi-structured interviews were conducted with online teacherpreneurs who ranked in the top 1% of sellers on TeachersPayTeachers.com for profits earned. In phase two, the results of the interviews were used to develop a quantitative survey, which was distributed to an international sample of 412 TeachersPayTeachers.com sellers with various levels of experience and sales success. Results from both phases were analyzed separately and together, indicating that online teacherpreneurs viewed themselves as helpful, hard-working, creative, and organized. While some online teacherpreneurs worked in supportive school environments, others worked in unsupportive or ambivalent schools. Most online teacherpreneurs kept their online business and classroom teaching separate. They reported that online teacherpreneurship involved a variety of practices including creating educational resources, collaborating with teachers, collaborating with fellow teacherpreneurs, and engaging in entrepreneurial endeavors such as marketing. They also believed they experienced impacts including improvements to teaching practice, teacher leadership opportunities, and some professional stressors. Implications for online teacherpreneurs and other stakeholders including teachers, school and district leaders, and teacher educators are considered.

The problem under investigation was to determine if a specific outline-style learning guide, called a Learning Agenda (LA), can improve a college algebra learning environment and if learner control can reduce the cognitive effort associated with note-taking in this instance. The 192 participants were volunteers from 47 different college algebra and pre-calculus classes at a community college in the southwestern United States. The approximate demographics of this college as of the academic year 2016 – 2017 are as follows: 53% women, 47% men; 61% ages 24 and under, 39% 25 and over; 43% Hispanic/Latino, 40% White, 7% other. Participants listened to an approximately 9-minute video lecture on solving a logarithmic equation. There were four dependent variables: encoding as measured by a posttest – pretest difference, perceived cognitive effort, attitude, and notes-quality/quantity. The perceived cognitive effort was measured by a self-reported questionnaire. The attitude was measured by an attitude survey. The note-quality/quantity measure included three sub-measures: expected mathematical expressions, expected phrases, and a total word count. There were two independent factors: note-taking method and learner control. The note-taking method had three levels: the Learning Agenda (LA), unguided note-taking (Usual), and no notes taken. The learner control factor had two levels: pausing allowed and pausing not allowed. The LA resulted in significantly improved notes on all three sub-measures (adjusted R2 = .298). There was a significant main effect of learner control on perceived cognitive effort with higher perceived cognitive effort occurring when pausing was not allowed and notes were taken. There was a significant interaction effect of the two factors on the attitude survey measure. The trend toward an improved attitude in both of the note-taking levels of the note-taking factor when pause was allowed was reversed in the no notes level when pausing was allowed. While significant encoding did occur as measured by the posttest – pretest difference (Cohen’s d = 1.81), this measure did not reliably vary across the levels of either the note-taking method factor or the learner control factor in this study. Interpretations were in terms of cognitive load management, split-attention, instructional design, and note-taking as a sense-making opportunity.
