The Impact Of Guided Notes Intervention On Learning Achievement, Quality Of Notes, And Perception, Bryan Richard Biggers

STEMPS Theses & Dissertations

Guided notes in the form of teacher-prepared materials that guide students through the lesson with cues and space have been recommended as a possible aid to support student learning. The present study investigated the results of guided notes on the students’ learning achievement, the quality of the students’ notes, and the students’ perceptions of note-taking. Sixty students were enrolled in an eight-week, asynchronous, online, general education course and were divided into nonintervention and intervention groups where the nonintervention groups took notes without support while the students in the intervention group took notes with guided notes during weeks two through seven. …

Mapping The Older User’S Journey: Building Ux With Theories Of Cognitive Aging, Aichatou Diaw

CMC Senior Theses

The aging global population represents a pressing consideration for user experience (UX) designers. The field of cognitive aging research focuses on characterizing and explaining changes in cognitive functions, such as memory, attention, perception, and problem-solving that occur as people age. Understanding these changes is vital for crafting interfaces that cater to a broader demographic. With the hope of creating more inclusive digital interfaces, this thesis explores the application of three cognitive aging theories, Cognitive Reserve, Cognitive Load Theory, and Controlled Processing, in order to examine their implications for UX design. By integrating insights from these theories, designers can make digital …

Reduction Of Cognitive Load In Immersive Virtual Reality With Multisensory Cues, Daniel Wilson

Theses

This study investigated the effects of multimodal interfaces and immersive virtual environments on cognitive load. Participants played a first-person target shooting game with either a virtual reality headset or on a monitor, using visual, auditory-visual, and a haptic-visual interfaces. Performance and self-reported data about cognitive load and spatial presence were collected for each interface. The study found that both immersive environments and multimodal interfaces reduced cognitive load. Additionally, an interaction was seen such that multimodal interfaces were more effective at reducing cognitive load in immersive environments. These findings indicate that the addition of more modalities into interfaces, especially in highly …

Investigating Division Quest: A Text-Based Adventure Narrative Game For Overcoming Difficulties Of Mitosis Learning, Amanda G. Conner

Electronic Theses and Dissertations

Mitosis learning is a source of struggle for many introductory biology students. Much of this difficulty stems from an overwhelming amount of terminology and moving pieces as well as the abstract nature of cellular processes. Game-based learning (GBL) has been used in other contexts to reduce cognitive load and provide relatable experiences upon which students can construct their mental models. However, commercial GBL is often expensive and difficult to align with individual instructor teaching preferences and learning objectives. In this study, we use a mixed methods approach to explore the use of a GBL tool made in Twine to overcome …

Using Dynamic Task Allocation To Evaluate Driving Performance, Situation Awareness, And Cognitive Load At Different Levels Of Partial Autonomy, Viraj R. Patel

Theses and Dissertations

The state of the art of autonomous vehicles requires operators to remain vigilant while performing secondary tasks. The goal of this research was to investigate how dynamically allocated secondary tasks affected driving performance, cognitive load, and situation awareness. Secondary tasks were presented at rates based on the autonomy level present and whether the autonomous system was engaged. A rapid secondary task rate was also presented for two short periods regardless of whether autonomy was engaged. There was a three-minute familiarization phase followed by a data collection phase where participants responded to secondary tasks while preventing the vehicle from colliding into …

Interactive Computer-Based Simulations As Exploratory Learning Activities., Derek Mcclellan

Electronic Theses and Dissertations

Typical college lectures follow a direct instruction framework, where instructors deliver a lecture, followed by an activity. Exploratory learning flips this routine by providing students with an activity prior to instruction. Research suggests that this inversion benefits students’ conceptual understanding and ability to transfer their knowledge. The majority of exploratory learning tasks in the literature are problem-solving activities. The current work investigates the use of computer-based simulations during exploratory learning, and whether manipulating the cognitive load of the activity impacts learning. In Experiment 1, undergraduate students (N=66) were randomly assigned to explore a simulation-based circuit construction activity prior …

Leveraging Simulation To Understand Nursing Student Learning In Technologically Complex Environment, Deborah Rojas

UNLV Theses, Dissertations, Professional Papers, and Capstones

Introduction The adoption of simulation technologies in schools of nursing has increased significantly over the last 5 years. Results regarding the use of simulation technology have been positive. The use of simulation technologies has been developed to include complex nursing situations that resemble real clinical settings. Research has demonstrated that memory recall is better in an environment that is the same or similar to the environment in which the learning took place (Krokos et al., 2018). For this reason, educators have used simulation technologies to create realistic environments where students can learn. However, learning outcomes in simulations are affected by …

Impact Of Applying Visual Design Principles To Boardwork In A Mathematics Classroom, Jennifer Rose Canizales

Theses and Dissertations

Though black boards and white boards have been a fundamental tool in the classroom for over a century, little research has been done on how to best design and present information using these boards. My study takes visual design principles and applies them to boardwork in a mathematics classroom to better organize and clarify the content. This research shows that students notice boardwork, have strong opinions on what makes boardwork good, and that the application of design principles on boards has a significant impact on students and the teacher. Students felt their cognitive load was lightened and that they were …

Untraining Gender Bias: An Eye-Tracking Study, Ripujit S. Bamrah

Master's Projects

In recent years, social cognitive theory has emphasized the role of cognitive processes in shaping perceptions and behavior related to gender bias. By examining the impact of targeted training interventions, this study seeks to better understand the influence of such processes on decision-making in the context of character selection. This human-computer interaction study explores the potential of intervention-based training to untraining gender bias in character selection. With an increasing need to address gender bias in various domains, understanding the impact of gender-based training becomes crucial. According to our hypothesis, exposure to masculine characters would boost people’s preference for female- intellectualized …

Identifying Self-Regulation Strategies Students Use When Cognitive Load Occurs, Linyu Luo

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

When the amount of information to process exceeds students’ capacity to do so, that indicates a problem in the learning environment that will hinder students’ successful learning. This study found that students use a variety of strategies to help them manage their own learning when they felt overwhelmed by the amount of information they needed to process. Further, these strategies differed from those typically expected of students when they are not overwhelmed.

Are All Pictures Worth 1,000 Words? An Investigation Of Fit Between Graph Type And Performance On Accounting Data Analytics Tasks, Shawn Paul Granitto

USF Tampa Graduate Theses and Dissertations

The usefulness of accounting data is directly dependent on the presentation and interpretation of the data (DeSanctis and Jarvenpaa 1989; Brown-Liburd et al. 2015; Cao et al. 2015). While both corporate accounting and public accounting have a large focus on data analytics and visualizations, accountants in both fields have reported to have minimal experience creating visualizations and observe a growing use of visualizations within their role (Krumwiede 2019; Buchheit et al. 2020; Gibson et al. 2020). Vessey (1991) finds that the appropriateness of a visualization can impact a user’s decision-making performance. Although prior studies have provided suggestions of when to …

How Do We Represent Possibilities In The Visual World? — An Analysis Of Amodal Completion Under Cognitive And Perceptual Load., Camden Parker

Dartmouth College Undergraduate Theses

How do cognitive and perceptual load affect the way we experience the world when the visual scene is incomplete or partially occluded? The present study seeks to answer this question with a series of experiments based on primed matching, amodal completion, and load theory. In Experiment 1, we replicated results that amodal completion is automatic and supports multiple possible completions. In Experiment 2, we found that working memory load decreases the priming effects of both partially occluded and fully visible shapes. In Experiment 3, we found that perceptual load decreases the priming effect of partially occluded shapes more so than …

A …

Cognitive Resources Are Recruited Consistently Across People During Story Listening, Matthew T. Bain

Electronic Thesis and Dissertation Repository

Degraded speech encoding as a result of hearing loss increases cognitive load and makes listening effortful. Standard hearing assessment does not capture this cognitive impact of hearing impairment. Speech-in-noise testing measures intelligibility for isolated sentences that are typically not engaging and lack meaningful context. These materials may not capture the processes involved in everyday listening situations, in which people are often intrinsically motivated to comprehend the speech they are hearing. The current study explored a novel approach using natural, spoken stories. We first characterized time courses of executive load during story listening in young individuals with normal hearing using a …

Counterfactual Thinking And Racial Bias When Judging Crime Scenarios, Megan M. Capodanno

Psychology Theses

Counterfactual thinking has been described by researchers as imagining alternative outcomes to a previous event (i.e., how that event could have turned out differently). Research has shown susceptibility towards systemic biases in this thought pattern. Specifically, these biases can include racial prejudices, such as decision-making favoring one race over another, and attribution errors, such as blaming a victim for an unfortunate circumstance. Research suggests that factors that increase the use of heuristics lead to increased victim blaming, racially biased decisions, and counterfactual thinking. The current studies suggest that counterfactual thinking has a positive relationship with blame assignment and that both …

Cognitive Load Detection For Advanced Driver Assistance Systems, Prathamesh Ayare

Electronic Theses and Dissertations

In this thesis, we investigate cognitive load detection and classification based on minimally invasive methods. Cognitive load detection is crucial for many emerging applications such as advanced driver assistance systems (ADAS) and industrial automation. Numerous studies in the past have reported several psychological measures, such as eye-tracking, electrocardiogram (ECG), electroencephalogram (EEG), as indicators of cognitive load. However, existing physiological features are invasive in nature. Consequently, the objective of this study is to determine the feasibility of non-invasive features such as pupil dilation measurements low-cost eye-tracker with minimal constraints on the subject for cognitive load detection. In this study, data from …

Electronic Thesis and Dissertation Repository

Balance is an important determinant of physical function and falls risk. This study sought to determine the effect of unilateral and bilateral perturbations, with and without cognitive load, on leg muscle activity in healthy young and older adults, as well as identify the influence of ankle power on postural and functional performance. Using a split-belt treadmill system, participants experienced unilateral and bilateral accelerations of the treadmill, without and with the Stroop test. Surface electromyography (EMG) from eight lower limb muscles was recorded from the right leg. EMG onset latency following perturbation onset, and root mean square of the muscle bursts …

Effects Of Difficult-To-Read Materials On Learning, Kala Lane Taylor

Doctoral Dissertations

Some researchers have found difficult-to-read, disfluent materials can improve learning. Thus, this dissertation is comprised of three studies investigating the effects of difficult-to-read materials on learning. In Study I, we used an adapted alternating treatments design to compare sight-word learning in three students with intellectual disability when flashcards were presented in easy-to-read (i.e., fluent) and difficult-to-read (i.e., disfluent) fonts. All students learned words presented in both fonts; however, two learned more words presented in fluent font, and the third experienced no differences between conditions. Another area where difficult-to-read material could affect learning is multicultural reading curricula, which often include diverse …

Use Of Pope Engagement Index To Measure Cognitive Load Of Physical Modeling Activities In Organic Chemistry, Jenifer Calvert

Master of Science in Chemical Sciences Theses

Understanding how students learn and process information is critical to developing physical modeling activities that facilitate student learning by decreasing cognitive load in the working memory. Optimizing cognitive load during physical modeling activities in organic chemistry is the key to effective and efficient learning. Using EEG (electroencephalogram) and eye tracking technologies, researchers measured and recorded the cognitive processing of participants while they completed a chiral physical modeling activity. Analysis of the data using the Engagement Index developed by Pope et al provided information necessary to develop curriculum that does not undermine student learning due to excessive cognitive load.

Conformity And Cognitive Load In An Asch-Like Paradigm Study, Kaylee Baker

CUP Undergraduate Research

Objective: Conformity is an important phenomenon to examine as it has the potential to influence a vast majority of people in everyday life, especially with the current technology of social media available. Factors that affect conformity rates have had little examination in the past, but are important to note in order to fully understand this behavior of conformity. I designed this study to observe the potential effects of one such factor, cognitive load, on conformity rates in an online setting with the goal of generalizing results to the effects of social media in our contemporary society. Design: I devised an …

Visual And Animated Response Formats In Web Surveys: Do They Produce Better Data, Or Is It All Just Fun And Games?, Duncan Rintoul

University of Wollongong Thesis Collection 2017+

The way in which a survey question is presented to a respondent can make a considerable difference to how they understand what is being asked of them, how they think about the question, and ultimately the answer they give. The rapid and widespread uptake of web surveys in market and social research has made it possible for researchers to start using a range of visual, colourful and interactive response formats that had never previously been possible – or at least practical – on paper. Advocates of these new response formats have argued that they offer significant benefits for respondent engagement …

Developing And Validating A Quality Of Delivery Scale And Assessing Adult-Trainees’ Cognitive Load, Motivation, And Compliance, Kelsey P. Moore

Theses and Dissertations--Communication

Effective communication is crucial for successful behavior change. However, despite much research in training and development, instructional communication, and public health surrounding communication, it is still unclear what constitutes such effective delivery behaviors, especially for an adult learner population (those over 25 years old). Using cognitive load theory and cognitive-affective theory of learning with media as theoretical frameworks, this dissertation proposes a quality of delivery scale for measuring effective communication across instructional settings with an adult learner audience. Informed by public health, training and organizational communication, as well as adult education and instructional communication, the final valid and reliable QD …

Learning Chinese Characters And German Words Using Multimedia, Cheuk Yue Fung

Master's Theses

This study applies cognitive theory of multimedia learning and cognitive load theory to foreign language learning and examines in what conditions English-speakers benefit most from multimedia instruction. Sixty-four English-speaking college students learned either German words or Chinese characters. The reason for comparing these two languages is to assess the differences between low-knowledge and high-knowledge learners. We assume English-speakers have a better linguistic knowledge for learning German words than Chinese characters, because of the closer relationship between English and German languages than between English and Chinese languages. There were four cue conditions in which participants received either no cue, a verbal …

Teachers Learning To Teach: A Phenomenological Exploration Of The Lived Experience Of Cognitive Load For Novice Teachers, Mark Hebert

CUP Ed.D. Dissertations

Cognitive load is a relevant phenomenon experienced by novice teachers moment-to-moment in complex classroom environments. Teachers learning to teach within the classroom daily encounter mental workload, but the latter has played little part in learning design for teachers, although other professions demanding complex performanes have made use of Cognitive Load Theory and Cognitive Task Analysis for learning design and for the reduction of cognitive load. Exploration of the lived experience of cognitive load was the focus of this study. The purpose of this phenomenological study was to describe the limits of mental capacity and the mental liberty experienced by teachers …

Decision Making In The Sciences: Understanding Heuristic Use By Students In Problem Solving, Elizabeth Csikar

STEMPS Theses & Dissertations

The purpose of this study was to examine the use of heuristics by students and gain insight into the thought process behind their problem-solving skills. The study used an adaptive narrative as the information delivery medium. An adaptive narrative was chosen because it could be designed to simulate decision making processes encountered in real world situations. Students enrolled in an introductory biology major class were chosen for the study because their fields of interest all require complex problem solving and decision-making skills. It was of interest to investigate what decisions were made when heuristics were given and how that may …

The Truthiness Effect: The Influence Of Nonprobative Photos On Truth Judgments, Laura N. Mangus

Seton Hall University Dissertations and Theses (ETDs)

Truthiness is used to describe a person’s instinctive and rapid judgment about the truth of a claim, with no regard to logic or fact. Recent research has shown that a photo can influence a person to believe a claim is true, even if the photo used is non-probative. This effect is hypothesized to occur because photographs make claims easier to process while also enabling one to retrieve related thoughts and images to mind, which can then be mistaken for familiarity and truth (Newman, Garry, Bernstein, Kantner, & Lindsay, 2012). Cognitive load and response time manipulation were factors that had not …

Human Systems Integration Of An Extravehicular Activity Space Suit Augmented Reality Display System, Paromita Mitra

Theses and Dissertations

During an extravehicular activity (EVA), the role of an astronaut involves a multitude of complex tasks. Whether that task is a science experiment aboard the International Space Station, or traversing extraterrestrial terrain – attention, communication, and instruction are essential. As an aid, augmented reality (AR) can portray suit informatics and procedures within line-of-sight while minimizing attentional loss. Currently, there exists little research highlighting the human systems considerations to qualify AR systems for space suit applications. This study quantifies user interface (UI) and human performance measures for an AR prototype on the Mark III space suit. For user testing, 21 military …
