Augmented reality offers a unique and innovative way to interact and connect with the natural world through the digital world. In an effort to better facilitate learning, this project makes use of web-based augmented reality. This project employs JavaScript libraries, AR.js and Three.js, to provide an augmented reality experience that better links real-world objects to information in a more digestible format. As well as discusses the many issues with technology and how to work around them and ultimately solve them.
Bad actor reporting has recently grown in popularity as an effective method for social media attacks and harassment, but many mitigation strategies have yet to be investigated. In this study, we created a simulated social media environment of 500,000 users, and let those users create and review a number of posts. We then created four different post-removal algorithms to analyze the simulation, each algorithm building on previous ones, and evaluated them based on their accuracy and effectiveness at removing malicious posts. This thesis work concludes that a trust-reward structure within user report systems is the most effective strategy for removing malicious content while minimizing the removal of genuine content. This thesis also discusses how the structure can be further enhanced to accommodate real-world data and provide a viable solution for reducing bad actor online activity as a whole.
The purpose of this study was to investigate the relationships between cognitive engagement and learning performance on an instructional module about misinformation on social media. A total of 133 undergraduate students participated in the study. They were surveyed for demographic characteristics, social media activity, and self-efficacy before being randomly assigned to one of four instructional conditions (passive, active, constructive, control). Additional measures included a pre-test, post-test and an instrument measuring users’ satisfaction with their instructional experience.
The study produced several statistically significant differences: (a) in the ability of demographic factors encompassing age, gender and years in college to predict the prior knowledge of misinformation on social media; (b) between the means of the three treatment and one control groups and their scores on the post-test assessment controlling for prior knowledge; and (c) between the means of the three treatment and one control groups and time necessary to complete instruction. Using a regression analysis, no significant differences were found with respect to information-focused self-efficacy factors being able to predict prior knowledge of misinformation on social media. The findings from this study can contribute to the basis of support for the use of the Interactive, Constructive, Active, Passive (ICAP) framework in assessing the use of cognitive engagement in designing instruction.
The similarity attraction hypothesis posits that humans are drawn toward others who behave and appear similar to themselves. Two experiments examined this hypothesis with middle-school students learning electrical circuit analysis in a computer-based environment with an Animated Pedagogical Agent (APA). Experiment 1 was designed to determine whether matching the gender of the APA to the student has a positive impact on learning outcomes or student perceptions. One hundred ninety-seven middle-school students learned with the computer-based environment using an APA that matched their gender or one which was opposite in gender. Female students reported higher program ratings when the APA matched their gender. Male students, on the other hand, reported higher program ratings than females when the APA did not match their gender. Experiment 2 systematically tested the impact of providing learners the choice among four APAs on learning outcomes and student perceptions. Three hundred thirty-four middle-school students received either a pre-assigned random APA or were free to choose from four APA options: young male agent, older male agent, young female agent, or older female agent. Learners had higher far transfer scores when provided a choice of animated agent, but student perceptions were not impacted by having the ability to make this choice. We suggest that offering students learner control positively impacts student motivation and learning by increasing student perceptions of autonomy, responsibility for the success of the instructional materials, and global satisfaction with the design of materials.
